[U-Boot] [PATCH] flash: Add optional verify-after-write feature
by Stefan Roese 22 Apr '13

22 Apr '13

Sometimes it might make sense to verify the written data to NOR flash. This patch adds this feature. To enable this verify-after-write, you need to define CONFIG_SYS_FLASH_VERIFY_AFTER_WRITE in your board config header.

[U-Boot] [PATCH 1/3] ppc4xx: Add SPL support
by Stefan Roese 22 Apr '13

22 Apr '13

This patch adds SPL booting support (NOR flash) for the PPC4xx platforms. This SPL booting (Falcon mode) will be used by the upcoming lcd4_lwmon5 board port (lwmon5 variant).

[U-Boot] [PATCH 1/3] iomux-v3: Place pad control definitions into common file
by Fabio Estevam 22 Apr '13

[U-Boot] [PATCH] imx: Add support for the SabreSD shipped with i.MX6DL
by Pierre Aubert 22 Apr '13

22 Apr '13

The SabreSD platform is available with i.MX6Q or i.MX6DL. This patch adds the support of the i.MX6DL. The config file and the board directory are renamed to remove the reference to the MX6Q.

[U-Boot] USB detection in u-boot oin our custom board
by amit 22 Apr '13

22 Apr '13

Sir, We are having our own custom board based on the FDI design,on which we are not able to mount USB. In the eaboard configuration files support for usb in the u-boot is there and we have commands to check the usb inserted. But this was not the case with FDI board,there were no commands for usb in uboot. So we inserted the files from the eaboard to our code and we were able to check USB command in u-boot. my query are Do fdi board support USB? When i am executing the below command following errors are coming: [code] uboot> usb reset [code] [Quote] (Re)start USB...

[U-Boot] [PATCH v5] add support for the palm treo 680 board
by Mike Dunn 20 Apr '13

20 Apr '13

A quick overview of u-boot implementation on the treo 680... The treo 680 has a Diskonchip G4 nand flash chip. This device has a 2k region that maps to the system bus at the reset vector in a NOR-like fashion so that it can be used as the boot device. The phone is shipped with this 2k region configured as write-protected (can't be modified) and programmed with an initial program loader (IPL). At power-up, this IPL loads the contents of two flash blocks to SDRAM and jumps to it. The capacity of the two blocks is not large enough to hold all of u-boot, so a u-boot SPL is used. To conserve flash space, these two blocks and the necessary number of subsequent blocks are programmed with a concatenated spl + u-boot image. That way, the IPL will also load a portion of u-boot proper, and when the spl runs, it relocates the portion of u-boot that the IPL has already loaded, and then resumes loading the remaining part of u-boot before jumping to it. The default_environment is used (CONFIG_ENV_IS_NOWHERE) because I didn't think that having a writable environment was worth the cost of a flash block, although adding it would be straightforward. I abuse the CONFIG_EXTRA_ENV_SETTINGS option to specify the usbtty for the console (CONFIG_SYS_CONSOLE_IS_IN_ENV). Support for the LCD is included, but currently it is only useful for displaying the u-boot splash screen. But if u-boot is built without the usbtty console, it does display the auto-boot progress nicely.

Thanks. + + +Intro +===== + +Yes, you can program u-boot onto the flash of your Palm Treo 680 so that u-boot +(then Linux, Android, ...) runs at power-up. This document describes how, and +gives some implementation details on this port of u-boot and describes how the +Treo 680 boots from reset. + +But first, I probably don't need to tell you that after doing this, your phone +will no longer run PalmOS. You *may* be able to later restore your phone to its +original state by creating a backup image of the flash before writing u-boot +(details below), but this is not heavily tested and should not be relied upon. +There is also the possibility that something may go wrong during the process of +programming u-boot, leaving you with a bricked phone. If you follow these +instructions carefully this chance will be minimized, but I do not recommend +that you program u-boot onto a phone that you can not afford to lose, and +certainly not one that contains important data that is not backed up elsewhere. +I AM NOT RESPONSIBLE FOR THE LOSS OF YOUR PHONE. DO THIS AT YOUR OWN RISK. +Having said that, feel free to send me a note cursing me out if something does +go wrong, but please tell me what happened exactly. For that matter, I'd love +to hear from you if you succeed. + + + +Details on the SPL +================== + +The docg4 features a 2k region at the start of its address space that interfaces +to the system bus like a NOR flash. This allows the docg4 to function as a boot +ROM. The Treo 680 uses this feature. The contents of this 2k region are +write-protected and can not be reprogrammed. Fortunately, the code it contains +does what we need to do, at least partially. After some essential hardware +initialization (like the SDRAM controller), it runs an IPL (initial program +loader) that copies 128K (no more, no less) from flash to a fixed address in +SDRAM (0xa1700000) and jumps to it. 128K is too small for u-boot, so we use it +to load a u-boot secondary program loader (SPL). But since our SPL only +occupies a little over 1k, we can economize on flash usage by having the IPL +load a portion of u-boot proper as well. We let the IPL load the first 128k of +a concatenated spl + u-boot image, and because the SPL is placed before u-boot +proper, the IPL jumps to the SPL, which copies the portion of u-boot that the +IPL has already loaded to its correct SDRAM address, and then loads the +remainder of u-boot and jumps to it. + + + +The docg4's "reliable mode" +=========================== + +This is a special mode of operation of the docg4's integrated controller whereby +consecutive pairs of 2k regions are used in parallel (in some fashion) to store +2k of data. In other words, the normal capacity is halved, but the data +integrity is improved. In this mode, the data is read or written from pages in +even-numbered 2k regions (regions starting at 0x000, 0x1000, 0x2000, ...). The +odd-numbered 2k regions (regions starting at 0x800, 0x1800, 0x2800, ...) are +transparently used in parallel. In reliable mode, the odd-numbered 2k regions +are not meant to be read or written directly. + +Reliable mode is used by the IPL because there is not enough space in its 2k +footprint to implement the BCH ecc algorithm. Data that is read while reliable +mode is enabled must have been written in reliable mode, or the read fails. +However, data written in reliable mode can also be read in normal mode (just not +as reliably), but only from the even-numbered 2k regions; the odd-numbered 2k +regions appear to contain junk, and will generate ecc errors. When the IPL and +SPL read from flash, the odd-numbered 2k regions are explicitly skipped. The +same is true for the flash_u-boot utility when it writes the u-boot image in +reliable mode. + +The docg4 Linux driver supports writing in reliable mode (it is enabled by the +module parameter), but not reading. However, the u-boot docg4_spl driver does +read in reliable mode, in the same fashion as the IPL. + + + +Details on the IPL and its data format +====================================== + +Starting from block 5 and counting upward, the IPL will search for and load the +first two blocks it finds that contain a magic number in the oob of the first +page of the block. The contents are loaded to SDRAM starting at address +0xa1700000. After two blocks have been loaded, it jumps to 0xa1700000. The +number of blocks loaded and the load address in SDRAM are hard-coded; only the +flash offset of the blocks can vary at run-time (based on the presence of the +magic number). + +In addition to using the docg4's reliable mode, the IPL expects each 512 byte +page to be written redundantly in the subsequent page. The hardware is capable +of detecting bit errors (but not correcting them), and if a bit error is +detected when a page is read, the page contents are discarded and the subsequent +page is read. + +Reliable mode reduces the capacity of a block by half, and the redundant pages +reduce it by half again. As a result, the normal 256k capacity of a block is +reduced to 64k for the purposes of the IPL/SPL. + +For the sake of simplicity and uniformity, the u-boot SPL mimics the operation +of the IPL, and expects the image to be stored in the same format. + + + +Instructions on Programming u-boot to flash +=========================================== + +To program u-boot to your flash, you will need to boot the Linux kernel on your +phone using a PalmOS bootloader such as cocoboot. The details of building and +running Linux on your Treo (cross-compiling, creating a root filesystem, +configuring the kernel, etc) are beyond the scope of this document. The +remainder of this document describes in detail how to program u-boot to the +flash using Linux running on the Treo. + + + +Hardware Prerequisites +====================== + +A Palm Treo 680: + (dugh) + +A Palm usb cable: + You'll need this to establish a usbtty console connection to u-boot from a + desktop PC. Currently there is no support in u-boot for the pxa27x keypad + (coming soon), so a serial link must be used for the console. + These cables are still widely available if you don't already have one. + +A Linux desktop PC. + You may be able to use Windows for the u-boot console if you have a usb driver + that is compatible with the Linux usbserial driver, but for programming u-boot + to flash, you'll really want to use a Linux PC. + + + +Treo-side Software Prerequisites +================================ + +Linux bootloader for PalmOS: + + Cocoboot is the only one I'm aware of. If you don't already have this, you + can download it from + https://download.enlightenment.org/misc/Illume/Treo-650/2008-11-13/sdcard-b… + which is a compressed tar archive of the contents of an sd card containing + cocoboot. Use mkdosfs to create a fat16 filesystem on the first primary + partition of the card, mount the partition, and extract the tar file to it. + You will probably need to edit the cocoboot.conf file to customize the + parameters passed to the kernel. + + + +Linux kernel: + + The kernel on the Treo 680 is still a little rough around the edges, and the + official kernel frequently breaks on the Treo :( A development kernel + specifically for the Treo 680 can be found on github: + http://github.com/mike-dunn/linux-treo680 + The master branch of this tree has been tested on the Treo, and I recommend + using this kernel for programming u-boot. As of this writing, there may be a + bug in the docg4 nand flash driver that sometimes causes block erasures to + fail. This has been fixed in the above tree. + + If you choose to use the official kernel, it must contain the docg4 driver that + includes the reliable_mode module parameter. This was a later enhancement to + the driver, and was merged to the kernel as of v3.8. Do not try to use an + earlier kernel that contains the docg4 driver without support for writing in + reliable mode. If you try to program u-boot to flash with the docg4 driver + loaded without the reliable_mode parameter enabled, you *will* brick your + phone! + + For the purpose of programming u-boot to flash, the following options must be + enabled in the Treo kernel's .config: + + CONFIG_MTD=y + CONFIG_MTD_CMDLINE_PARTS=y + CONFIG_MTD_CHAR=y + CONFIG_MTD_NAND_DOCG4=m + + Note that the docg4 nand driver is configured as a module, because we will + want to load and unload it with reliable_mode enabled or disabled as needed. + + You will also need to specify mtd partitions on the kernel command line. In + the instructions that follow, we will assume that the flash blocks to which + u-boot will be programmed are defined by the second partition on the device. + The u-boot config file (include/configs/palmtreo680.h) places the u-boot image + at the start of block 6 (offset 0x180000), which is the first writable + (non-protected) block on the flash (this is also where the PalmOS SPL starts). + The u-boot image occupies four blocks, so to create the u-boot partition, pass + this command line to the kernel: + mtdparts=Msys_Diskonchip_G4:1536k(protected_part)ro,1024k(bootloader_part),-(filesys_part) + This will create three partitions: + protected_part: the first six blocks, which are read-only + bootloader_part: the next four blocks, for the u-boot image + filesys_part: the remainder of the device + The mtdchar kernel device driver will use device nodes /dev/mtd0, /dev/mtd1, + and /dev/mtd2 for these partitions, respectively. Ensure that your root file + system at least has /dev/mtd1 if you are not running udev or mdev. + + +Userspace Utilities: + + In addition to everything necessary to provide a useful userspace environment + (busybox is indispensable, of course), you will need the mtd-utils package on + your root filesystem. I use version 1.5.0 of mtd-utils, and I suggest you use + this version as well, or at leat a version very close to this one, as + mtd-utils has tended to be fluid. + + Note that busybox includes a version of mtd-utils. These are deficient and + should not be used. When you run one of these utilities (nanddump, etc), + ensure you are invoking the separate executable from mtd-utils, and not the + one built into busybox. I recommend that you configure busybox with its + mtd-utils disabled to avoid any possibility of confusion. + + You will also need to cross-compile the userspace Linux utility in + tools/palmtreo680/flash_u-boot.c, which we will run on the Treo to perform the + actual write of the u-boot image to flash. This utility links against libmtd + from the mtd-utils package. + + + +Desktop PC-side Software Prerequisites +====================================== + +Terminal emulator application: + minicom, kermit, etc. + + +Linux kernel: + Compiled with CONFIG_USB_SERIAL enabled. Build this as a module. + + + +Recommended (Not directly related to u-boot) +============================================ + +Working directly on the Treo's tiny screen and keypad is difficult and +error-prone. I recommend that you log into the Linux kernel running on your +Treo from your desktop PC using ethernet over usb. The desktop's kernel must be +configured with CONFIG_USB_USBNET, CONFIG_USB_NET_CDCETHER, and +CONFIG_USB_NET_CDC_SUBSET. The Treo's kernel will need CONFIG_USB_ETH, and its +init script will need to start an ssh daemon like dropbear. Note that the usb0 +network interface will not appear on the desktop PC until the Treo kernel's usb +ethernet gadget driver has initialized. You must wait for this to occur (watch +the PC's kernel log) before you can assign usb0 an ip address and log in to the +Treo. If you also build the Treo's kernel with CONFIG_IP_PNP enabled, you can +pass its ip address on the kernel command line, and obviate the need to +initialize the network interface in your init script. + +Having the Palm usb cable connected to the host has the added benefit of keeping +power supplied to your Treo, reducing the drain on the battery. If something +goes wrong while you're programming u-boot to the flash, you will have lots of +time to correct it before the battery dies. + +I have encountered a situation where the kernel is sometimes unable to mount a +root filesystem on the mmc card due to the mmc controller not initializing in +time, (and CONFIG_MMC_UNSAFE_RESUME doesn't seem to help) so I recommend that +you build a minimal root filesystem into the kernel using the kernel's initramfs +feature (CONFIG_BLK_DEV_INITRD). If you want your root filesystem on the mmc +card, your init script can mount and switch_root to the mmc card after a short +sleep. But keep in mind that in this case you won't be able to use an mmc card +to transfer files between your desktop and the Treo once Linux is running. +Another option for transfering files is to mount an nfs filesystem exported by +the desktop PC. For greatest convenience, you can export the root filesystem +itself from your desktop PC and switch_root to it in your init script. This +will work if your initramfs init script contains a loop that waits for you to +initialize the usb0 network interface on the desktop PC; e.g., loop while a ping +to the desktop PC returns an error. After the loop exits, do the nfs mount and +call switch_root. (You can not use the kernel nfsroot feature because the +network will not be up when the kernel expects it to be; i.e., not until you +configure the usb0 interface on the desktop.) Use the nfs 'nolock' option when +mounting to avoid the need to run a portmapper like rpcbind. + + + +Preliminaries +============= + +Once Linux is running on your Treo, you may want to perform a few sanity checks +before programming u-boot. These checks will verify my assumptions regarding +all the Treo 680s out there, and also ensure that the flash and mtd-utils are +working correctly. If you are impatient and reckless, you may skip this +section, but see disclaimer at the top of this file! + +Load the docg4 driver: + + $ modprobe docg4 ignore_badblocks=1 reliable_mode=1 + +We tell the driver to use the docg4's "reliable mode" when writing because this +is the format required by the IPL, which runs from power-up and loads the first +portion of u-boot. We must ignore bad blocks because linux mtd uses out-of-band +(oob) bytes to mark bad blocks, which will cause the blocks written by PalmOS to +be misidentified as "bad" by libmtd. + +Check the kernel log to ensure that all's well: + + $ dmesg | tail + <... snip ...> + docg4 docg4: NAND device: 128MiB Diskonchip G4 detected + 3 cmdlinepart partitions found on MTD device Msys_Diskonchip_G4 + Creating 3 MTD partitions on "Msys_Diskonchip_G4": + 0x000000000000-0x000000180000 : "protected_part" + 0x000000180000-0x000000280000 : "bootloader_part" + 0x000000280000-0x000008000000 : "filesys_part" + +Ensure that the partition boundaries are as shown. (If no partitions are shown, +did you remember to pass them to the kernel on the command line?) We will write +u-boot to bootloader_part, which starts at offset 0x180000 (block 6) and spans 4 +256k blocks. This partition is accessed through the device node /dev/mtd1. + +The docg4 contains a read-only table that identifies blocks that were marked as +bad at the factory. This table is in the page at offset 0x2000, which is within +the partition protected_part (/dev/mtd0). There is a slight chance that one or +more of the four blocks that we will use for u-boot is listed in the table, so +use nanddump to inspect the table to see if this is the case: + + $ nanddump -p -l 512 -s 0x2000 -o /dev/mtd0 + ECC failed: 0 + ECC corrected: 0 + Number of bad blocks: 0 + Number of bbt blocks: 0 + Block size 262144, page size 512, OOB size 16 + Dumping data starting at 0x00002000 and ending at 0x00002200... + 0x00002000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff + <... snip ...> + +The format of the table is simple: one bit per block, with block numbers +increasing from left to right, starting with block 0 as the most significant bit +of the first byte. A bit will be clear if the corresponding block is bad. We +want to use blocks 6 throgh 9, so both of the two least significant bits of the +first byte must be set, as must the two most significant bits of the second +byte. If this is not true in your case (you are very unlucky), you should use +the first contiguous set of four good blocks after block 6, and adjust the +partition boundaries accordingly. You will also have to change the value of +CONFIG_SYS_NAND_U_BOOT_OFFS in include/configs/palmtreo680.h and recompile +u-boot. Because the two blocks loaded by the IPL do not have to be contiguous, +but our SPL expects them to be, you will need to erase any good blocks that are +at an offset prior to CONFIG_SYS_NAND_U_BOOT_OFFS, so that the IPL does not find +the magic number in oob and load it. Once you have done all this, the +instructions in this file still apply, except that the instructions below for +restoring the original PalmOS block contents may need to be modified. + +Next, use nanddump to verify that the PalmOS SPL is where we expect it to be. +The SPL can be identified by a magic number in the oob bytes of the first page +of each of the two blocks containing the SPL image.

This is +a consequence of reading pages that were written in reliable mode, and is +expected (these should all occur on pages in odd-numbered 2k regions; i.e., +0x800, 0xa00, 0xc00, 0xe00, 0x1800, 0x1a00, ...). The size of the file +bootloader_part.orig should be 1081344, which is 2048 pages, each of size 512 +plus 16 oob bytes. If you are using initramfs for the root filesystem, don't +forget to copy the file to permanent storage, such as an mmc card. + +If all of the above went well, you can now program u-boot. + + + +Programming u-boot +================== + +Our u-boot includes a small SPL that must be prepended to u-boot proper. From +the base u-boot source directory on your desktop PC: + + $ cat spl/u-boot-spl.bin u-boot.bin > u-boot-concat.bin + +cd to the tools/palmtreo680/ directory, and cross-compile flash_u-boot.c for the +Treo: + + $(CC) -o flash_u-boot $(CFLAGS) $(INCLUDEPATH) $(LIBPATH) flash_u-boot.c -lmtd + +Substitute variable values from your cross-compilation environment as +appropriate. Note that it links to libmtd from mtd-utils, and this must be +included in $(LIBPATH) and $(INCLUDEPATH). + +Transfer u-boot-concat.bin and the compiled flash_u-boot utility to the Treo's +root filesystem. On the Treo, cd to the directory where these files were +placed. + +Load the docg4 driver if you have not already done so. + + $ modprobe docg4 ignore_badblocks=1 reliable_mode=1 + +Erase the blocks to which we will write u-boot: + + $ flash_erase /dev/mtd1 0x00 4 + +If no errors are reported, write u-boot to the flash: + + $ ./flash_u-boot u-boot-concat.bin /dev/mtd1 + +You can use nanddump (see above) to verify that the data was written. This +time, "BIPO" should be seen in the first four oob bytes of the first page of all +four blocks in /dev/mtd1; i.e., at offsets 0x00000, 0x40000, 0x80000, 0xc0000. + +Shutdown linux, remove and re-insert the battery, hold your breath... + + + +Enjoying u-boot +=============== + +After you insert the battery, the u-boot splash screen should appear on the lcd +after a few seconds. With the usb cable connecting the Treo to your PC, in the +kernel log of your PC you should see + + <6>usb 3-1: New USB device found, idVendor=0525, idProduct=a4a6 + <6>usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 + <6>usb 3-1: Product: U-Boot 2013.01-00167-gd62ef56-dirty + <6>usb 3-1: Manufacturer: Das U-Boot + +Load the usbserial module on your desktop PC: + + $ modprobe usbserial vendor=0x0525 product=0xa4a6 + +and run your favorite terminal emulation utility (minicom, kermit, etc) with the +serial device set to /dev/ttyUSB0 (assuming this is your only usb serial +device). You should be at the u-boot console (type 'help'). + +There is not much that is unique about using u-boot on the palm treo 680. +Kernels can be loaded from mmc, flash, and from the desktop PC via kermit. You +can expand the size of the second partition on the flash to contain a kernel, or +else put the kernel(s) in their own partition. + +Nand commands work as expected, with the excepton that blocks not written by the +linux mtd subsystem may be misidentified by the u-boot docg4 driver as "bad" if +they contain data in the oob bytes. This will be the case for the blocks +containing the u-boot image, for example. To work around this, use 'nand scrub' +instead of 'nand erase' to erase these blocks, and 'nand read.raw' to read them +to memory. (It would be useful if u-boot's nand commands provided a way to +explicitly ignore "bad" blocks, because read.raw does not perform ecc.) The +'nand dump' command will read these "bad" blocks, however. + +Currently u-boot itself can only be programmed to flash from Linux; there is no +support for reliable mode in u-boot's docg4 flash driver. This should be +corrected soon. + + + +Customizing +=========== + +If you change u-boot's configuration significantly (adding or removing +features), you may have to adjust the value of CONFIG_SYS_NAND_U_BOOT_SIZE. +This is the size of the concatenated spl + u-boot image, and tells the SPL how +many flash blocks it needs to load. It will be rounded up to the next 64k +boundary (the spl flash block capacity), so it does not have to be exact, but +you must ensure that it is not less than the actual image size. If it is larger +than the image, blocks may be needlessly loaded, but if too small, u-boot may +only be partially loaded, resulting in a boot failure (bricked phone), so better +to be too large. The flash_u-boot utility will work with any size image and +write the required number of blocks, provided that the partition is large +enough. + +As the first writable block on the device, block 6 seems to make the most sense +as the flash offset for writing u-boot (and this is where PalmOS places its +SPL). But you can place it elsewhere if you like. If you do, you need to +adjust CONFIG_SYS_NAND_U_BOOT_OFFS accordingly, and you must ensure that blocks +preceeding the ones containing u-boot do *not* have the magic number in oob (the +IPL looks for this). In other words, make sure that any blocks that previously +contained the u-boot image or PalmOS SPL are erased (and optionally written with +something else) so that the IPL does not load it. Also make sure that the new +u-boot starting offset is at the start of a flash partition (check the kernel +log after loading the docg4 driver), and pass the corresponding mtd device file +to the flash_u-boot utility. + +The u-boot built-in default environment is used because a writable environment +in flash did not seem worth the cost of a 256k flash block. But adding this +should be straightforward. + + + +Restoring PalmOS +================ + +If you backed up the contents of bootloader_part flash partition earlier, you +should be able to restore it with the shell script shown below. The first two +blocks of data contain the PalmOS SPL and were written in reliable mode, whereas +the next two blocks were written in normal mode, so the script has to load and +unload the docg4 driver. Make sure that the mtd-utils nandwrite and flash_erase +are in your path (and are not those from busybox). Also double-check that the +backup image file bootloader_part.orig is exactly 1081344 bytes in length. If +not, it was not backed up correctly. Run the script as: + + ./restore_bootpart bootloader_part.orig /dev/mtd1 + +The script will take a minute or so to run. When it finishes, you may want to +verify with nanddump that the data looks correct before you cycle power, because +if the backup or restore failed, your phone will be bricked. Note that as a +consequence of reliable mode, the odd-numbered 2k regions in the first two +blocks will not exactly match the contents of the backup file, (so unfortunately +we can't simply dump the flash contents to a file and do a binary diff with the +original back-up image to verify that it was restored correctly). Also, +nanddump will report uncorrectable ecc errors when it reads those regions. + +#!/bin/sh + +if [ $# -ne 2 ]; then + echo "usage: $0: <image file> <mtd device node>" + exit 1 +fi + +# reliable mode used for the first two blocks +modprobe -r docg4 +modprobe docg4 ignore_badblocks=1 reliable_mode=1 || exit 1 + +# erase all four blocks +flash_erase $2 0 4 + +# Program the first two blocks in reliable mode. +# 2k (4 pages) is written at a time, skipping alternate 2k regions +# Note that "2k" is 2112 bytes, including 64 oob bytes +file_ofs=0 +flash_ofs=0 +page=0 +while [ $page -ne 1024 ];

[U-Boot] How do I use AM335x eth1 rather than eth0 ?
by Mark Jackson 20 Apr '13

20 Apr '13

We have a dual Ethernet board (based on the BeagelBone) but with both Ethernet ports connected. I'm wanting to use eth1 (rather than eth0), so in my board.c file, I changed:- static struct cpsw_slave_data cpsw_slaves[] = { { .slave_reg_ofs = 0x208, .sliver_reg_ofs = 0xd80, .phy_id = 0, }, { .slave_reg_ofs = 0x308, .sliver_reg_ofs = 0xdc0, .phy_id = 1, }, }; ... to ... static struct cpsw_slave_data cpsw_slaves[] = { { .slave_reg_ofs = 0x308, .sliver_reg_ofs = 0xdc0, .phy_id = 1, }, { .slave_reg_ofs = 0x208, .sliver_reg_ofs = 0xd80, .phy_id = 0, }, }; ... assuming that eth0 would now be ignored (as only 1 slave is configured). But (eg) dhcp still only responds on eth0 !?! What else do I have to change ? Cheers Mark J.

[U-Boot] [STATUS] v2013.04 released
by Tom Rini 20 Apr '13

20 Apr '13

Hey all, U-Boot v2013.04 has been released and uploaded to git and should be on the FTP server soon. The merge window is now open until May 4th and the next release, v2013.07 is scheduled for release on July 15th 2013 (the wiki is a bit off right now). Looking over the git log I see: - WARNING! ext4write syntax has been changed to match the other read/write commands. - Improved platform support for many ARM SoCs - Improved platform support on x86, PowerPC and MIPS too - More PowerPC targets migrated to the new SPL - global_data clean up and consolidation - Improved DFU support - Started work on generic board support (see common/board_*.c) - Added 'buildman' script. Like patman? You'll probably love buildman, give it a whirl and provide feedback. - And even more I've skimmed over! To repeat one thing and point out another: WARNING! ext4write syntax has been changed to match the other read/write commands. And: The mtest command is scheduled for removal in the next release. doc/README.memory-test explains the reasoning why. Thanks for all of your hard work everyone! -- Tom

[U-Boot] [PATCH v4 1/2] mx51evk: Update environment in order to allow booting a dt kernel
by Fabio Estevam 19 Apr '13

19 Apr '13

From: Fabio Estevam <fabio.estevam(a)freescale.com> Update the environment as done in other imx boards to allow easy switching between booting a non-dt kernel and a dt kernel. Change CONFIG_LOADADDR to 0x92000000, so that we can have the: - uImage at 0x92000000 - imx51-babbage.dtb at 0x91000000 ,which are adequate locations in RAM to avoid overlapping. Boot tested the following kernels: - 2.6.35 from FSL (11.09 branch) - 3.9-rc7 non-dt - 3.9-rc7 dt Signed-off-by: Fabio Estevam <fabio.estevam(a)freescale.com> --- Changes since v3: - None. Just make it part of a series now Changes since v2: - Mention the LOADADDR change in the commit log Changes since v1: - Do not remove mmcrootfstype - Fix typo in Subject - Improve commit log by adding the tested booted kernels include/configs/mx51evk.h | 42 +++++++++++++++++++++++++++++++++++++++--- 1 file changed, 39 insertions(+), 3 deletions(-) diff --git a/include/configs/mx51evk.h b/include/configs/mx51evk.h index cb3d938..4545a80 100644 --- a/include/configs/mx51evk.h +++ b/include/configs/mx51evk.h @@ -149,11 +149,15 @@ #define CONFIG_ETHPRIME "FEC0" -#define CONFIG_LOADADDR 0x90800000 /* loadaddr env var */ +#define CONFIG_LOADADDR 0x92000000 /* loadaddr env var */ #define CONFIG_EXTRA_ENV_SETTINGS \ "script=boot.scr\0" \ "uimage=uImage\0" \ + "fdt_file=imx51-babbage.dtb\0" \ + "fdt_addr=0x91000000\0" \ + "boot_fdt=try\0" \ + "ip_dyn=yes\0" \ "mmcdev=0\0" \ "mmcpart=2\0" \ "mmcroot=/dev/mmcblk0p3 rw\0" \ @@ -166,15 +170,47 @@ "bootscript=echo Running bootscript from mmc ...; " \ "source\0" \ "loaduimage=fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${uimage}\0" \ + "loadfdt=fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} ${fdt_file}\0" \ "mmcboot=echo Booting from mmc ...; " \ "run mmcargs; " \ - "bootm\0" \ + "if test ${boot_fdt} = yes || test ${boot_fdt} = try; then " \ + "if run loadfdt; then " \ + "bootm ${loadaddr} - ${fdt_addr}; " \ + "else " \ + "if test ${boot_fdt} = try; then " \ + "bootm; " \ + "else " \ + "echo WARN: Cannot load the DT; " \ + "fi; " \ + "fi; " \ + "else " \ + "bootm; " \ + "fi;\0" \ "netargs=setenv bootargs console=ttymxc0,${baudrate} " \ "root=/dev/nfs " \ "ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp\0" \ "netboot=echo Booting from net ...; " \ "run netargs; " \ - "dhcp ${uimage}; bootm\0" \ + "if test ${ip_dyn} = yes; then " \ + "setenv get_cmd dhcp; " \ + "else " \ + "setenv get_cmd tftp; " \ + "fi; " \ + "${get_cmd} ${uimage}; " \ + "if test ${boot_fdt} = yes || test ${boot_fdt} = try; then " \ + "if ${get_cmd} ${fdt_addr} ${fdt_file}; then " \ + "bootm ${loadaddr} - ${fdt_addr}; " \ + "else " \ + "if test ${boot_fdt} = try; then " \ + "bootm; " \ + "else " \ + "echo ERROR: Cannot load the DT; " \ + "exit; " \ + "fi; " \ + "fi; " \ + "else " \ + "bootm; " \ + "fi;\0" #define CONFIG_BOOTCOMMAND \ "mmc dev ${mmcdev}; if mmc rescan; then " \ -- 1.7.9.5
