[U-Boot-Users] fsload questions
by Charles Krinke 21 Dec '06

21 Dec '06

I have a setup with u-boot-1.1.6 with the nand/jffs2 subsystem enabled and I have a flash that has been formatted with 'flash_eraseall -j /dev/mtd0' in Linux. Additionally a PPC uImage for this 8241 target has been put on the flash. At this point, I reboot, set the mtdids and mtdparts and try an fsload and here is the result. I8000E> setenv mtdids nand0=atx-0 I8000E> setenv mtdparts mtdparts=atx-0:16M@0M(rootfs1) I8000E> fsload ### JFFS2 loading 'uImage' to 0x100000 Scanning JFFS2 FS: - ... read_nand_cached: error reading nand off 0xdfe200 size 8192 bytes read_nand_cached: error reading nand off 0xdfe000 size 8192 bytes read_nand_cached: error reading nand off 0xdffe00 size 8192 bytes off = 0xdffff8 magic 0x0 type 0x0 node.totlen = 0 . done. ### JFFS2 load complete: 936990 bytes loaded to 0x100000 I8000E> md 0x100000 00100000: 27051956 6ed7fc8a 4587f48c 000e4bde '..Vn...E.....K. 00100010: 00000000 00000000 dd803a34 05070201 ..........:4.... 00100020: 4c696e75 782d322e 362e3137 2e313100 Linux-2.6.17.11. ...

Why does the load appear to complete successfully, the bootm start, but then there is a GUNZIP error and the board reset? Charles

So check values of __got_start, __got_end, CFG_MONITOR_BASE and TEXT_BASE. And make sure that you give -msep-data option to GCC to support GOT (through a5 register).

[U-Boot-Users] i2c_init - is this a bug?
by Michael 20 Dec '06

20 Dec '06

Hi, guys. Here is something suspicious about i2c_init(int speed, int slaveadd), in i2c.c and fsl_i2c.c - the speed parameter passed to it is never used, instead the value is hard-coded. /* set clock */ writeb(0x3f, &I2C->fdr); Sets the speed. Shouldn't it be writeb(speed, &I2C->fdr); , with speed being the divider value? Regards, Mic

[U-Boot-Users] a little advice
by Charles Krinke 19 Dec '06

19 Dec '06

I am trying to get the 8555EP running with u-boot-1.1.6. I had previously received a u-boot-1.1.4 from Freescale with functioning 8555EP support, but when I put the 8555EP bsp into the 1.1.6 source, although it compiles and runs a bit, it does a bad trap at d00 (DataTLBError) when running. The trap occurs in env_relocate when malloc() is run. It appears to be the second or third malloc, not the first and I have looked at the bins in the malloc area and they are all just below the top of the 64Mb of ram nead 0x03ffffff. I wonder if someone could offer a spot of advice on where to look for troubles with malloc working in this environment as to where I might go looking next. Charles p.s. I apologize if this comes out html as I am using VPN back to the company webmail as I needed to head for home to cloister myself for a couple of days.

Users, I'm working on a MPC5200 based product and would like to add ethernet support at the u-boot level. Has anyone added (or attempted to add) Davicom DM9000A support to U-Boot? I see support for DM9000, but the interface to this part is significantly different. If not, can anyone point me to a good starting point for porting and existing driver?

Re: [U-Boot-Users] MPC8360E & Large DDR Capacities
by Russell McGuire 19 Dec '06

19 Dec '06

All After digging around it would seem that U-boot is resetting after the first direct access to DDR memory. I placed a number of statements and installed a 'memory test' function. I think the DDR init is failing due to the udelay(200) function early in the MPC8360E-MDS board files. The delay does not seem to be operational, so I 'think' the DDR gets enabled before the specked 200us delay that the MPC8360 manual requires. Anyone have any ideas what might cause the udelay function to not 'delay' as advertised. <My core clock is setup at 533 Mhz, but 200us should be will within the non-overflow capability>. -Russ -----Original Message----- From: Timur Tabi [mailto:timur@freescale.com] Sent: Monday, December 18, 2006 7:53 AM To: rmcguire(a)videopresence.com Cc: u-boot-users(a)lists.sourceforge.net Subject: Re: [U-Boot-Users] MPC8360E & Large DDR Capacities Russell McGuire wrote: > Does anybody know if there are any issues with using DDR capacities above > 256MB?

[U-Boot-Users] NAND boot from file
by Charles Krinke 18 Dec '06

18 Dec '06

I have been able to perform a nand boot with nand read and write.jffs2 like this: Write uImage Uboot> tftp 0x1000000 uImage Uboot> nand write.jffs2 0x1000000 0 0x100000 (reboot) Read uImage & boot from it Uboot> nand read 0x1000000 0 0x100000 Uboot> bootm 0x1000000 This works fine, but I am trying to understand how to boot from a uImage previously written on a formatted jffs2 flash by Linux-2.6.17.11 or if it is possible. I see some hints that this may be possible with mtdids, mtdparts, fsinfo and ls and would like to do something like Write uImage with Linux using 'cp uImage /mnt/flash' # flash_eraseall -j /dev/mtd0 # mount -t jffs2 /dev/mtdblock0 /mnt/flash0 # cp uImage /mnt/flash0 (reboot) Read uImage Uboot> setenv mtdids nand0=atx-0 Uboot> setenv mtdparts mtdparts=atx-0:16M@0M(boot) Uboot> <commandToDetermineImageOffset> <uImageOffset> Uboot> nboot <uImageOffset> There are a few issues. One is that I don't know the offset of the uImage as written by Linux. Another is I don't know if this is the right recipe or whether I am going in the right direction. Could you offer a couple of suggestions. Charles

[U-Boot-Users] MPC8360E & Large DDR Capacities
by Russell McGuire 18 Dec '06

18 Dec '06

Does anybody know if there are any issues with using DDR capacities above 256MB? I am attempting to use a 512MB DIMM at the moment, and am not sure if I am getting a SDRAM init issue that is causing U-boot to continuously reset, <Yes I have read the U-boot FAQ on this>, or whether I have hosed over the BAT setup trying to cache all 512MB. I see in the code there is a single CONFIG_VERY_BIG_RAM setting, and in the board.c file that 'may' effect the position of the final stack location. As well I have a question regarding a MAXIMUM supportable RAM by U-boot. I.e. could it go as high as 2 GB? And if so, what would the BAT settings look like. I am assuming that each bat on the E300 core can only map 256MB, so would it require all 8 BATS just to map the DDR? Or can the BATS just be enabled for the lower portions, or is there some nifty way to link them to span higher ranges than 256MB? As well I have mapped the DDRLAW0 to span a single 512MB range. Each CS0 and CS1 is mapped to handle 256MB. See my current BATS below: My Laws are using /* DDR: cache cacheable, first 256MB, should be 0x0000_0000 to 0x0FFF_FFFF*/ #define CFG_IBAT0L (CFG_DDR_SDRAM_BASE | BATL_PP_10 | BATL_MEMCOHERENCE) #define CFG_IBAT0U (CFG_DDR_SDRAM_BASE | BATU_BL_256M | BATU_VS | BATU_VP) #define CFG_DBAT0L CFG_IBAT0L #define CFG_DBAT0U CFG_IBAT0U /* DDR: cache cacheable, second 256MB, should be 0x1000_0000 to 0x1FFF_FFFF*/ #define CFG_IBAT1L ((CFG_DDR_SDRAM_BASE+0x10000000) | BATL_PP_10 | BATL_MEMCOHERENCE) #define CFG_IBAT1U ((CFG_DDR_SDRAM_BASE+0x10000000) | BATU_BL_256M | BATU_VS | BATU_VP) #define CFG_DBAT1L CFG_IBAT1L #define CFG_DBAT1U CFG_IBAT1U -Russ

[U-Boot-Users] closer to nboot
by Charles Krinke 18 Dec '06

18 Dec '06

I'm definitely getting closer so will answer part of my own question, but propose the next one. The following is working (mostly) uboot> tftp 0x1000000 uImage (its slightly smaller then 1Mbyte) uboot> nand write.jffs2 0x1000000 0x0 0x1000000 uboot> setenv bootdevice 0 uboot> nboot 0x1000000 At this point, I see: Loading from NAND 256MiB 3.3V, 8-bit, offset 0x0 Image Name: Linux-2.6.17.11 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 937470 Bytes Load Address: 00000000 Entry Point: 00000000 And then I get the uboot prompt back. I had thought that giving the address to the nboot command would get me a bit further, but apparently not. Also, I should note that I dont have mtdids or mtdparts defined at this stage. My assumption is that we are doing a raw write and read from the flash and that the .jffs2 argument just deals with the oob (out-of-band) bytes in a jffs2 manner. Charles

[U-Boot-Users] booting from nand/jffs2
by Charles Krinke 18 Dec '06

18 Dec '06

I am trying to understand how to boot a uImage contained on a NAND flash in JFFS2 format in u-boot-1.1.6. It looks like there are two choices. The first is to format the flash in linux and write a uImage from Linux to the flash, then use the flash as a file system and boot from the uImage file on the NAND/JFFS2 flash as shown by an 'ls' command. This one seems to be heading towards a black hole, but perhaps someone could help me understand the recipe a bit more. The second may be to use nand write.jffs2 to the flash from u-boot-1.1.6 and then use the nboot command. This one also seems to be heading towards a different black hole, with "NAND read error" being the end result (after a succesful write), but perhaps this has to do with the recipe again. Some advice would be greatly appreciated. Charles

[U-Boot-Users] ls of nand jffs2 flash
by Charles Krinke 17 Dec '06

17 Dec '06

I got past my malloc troubles this morning. It was the use of the u-boot.lds file from u-boot-1.1.4. Once I accomodated the changes to the linker script, things worked out fine with malloc. It turned out that the av_[] array was linked in as the first item after __u_boot_cmd_start. Now, on to the next issue. I am trying to setup so I can boot from a jffs2/NAND flash image that has been previously formatted using 'flash_eraseall -j' in linux-2.6.17.11. The flash does mount in u-boot-1.1.6, and I can do both a 'fsinfo' and 'ls' on it. The 'ls' does find the dozen or so files, but it takes about 10 minutes for the 'ls' to complete. I have one partition currently, and it is 16Mbytes. I could see that when linux copied files to the flash it started at the top (highest address) and worked its way down. When u-boot accesses the flash it starts at the bottom (lowest address) and works its way up. I am wondering if there is a notion of super-block that is not quite compatible between u-boot-1.1.6 and linux-2.6.17.11. Can you offer a spot of advice as to why it might take 10 minutes to complete an 'ls' on a formatted jffs2/nand flash? Charles

[U-Boot-Users] 8555EP malloc trouble
by Charles Krinke 17 Dec '06

17 Dec '06

I'm trying to get the Embedded Planet 8555 board running with u-boot-1.1.6. It has been running with 1.1.4. The current issue seems to the the av_ arrays in dlmalloc.c. Somehow, the first element (av_[0]->prev_size is initialized with gd->reloc_off and not zero as I believe it should be. Can someone tell me how or where any elements of the mbinptr array are manipulated before the calls to mem_malloc_init and malloc_bin_reloc in lib_ppc/board.c. There must be some other subroutine writing into this memory array area and I need a bit more understanding of what routines from board_init_f before malloc_bin_reloc might be involved. Charles

One aspect of our being is agony as Christ bore it, the other is triumph as Christ did after the cross, and we are in total identification from suffering to freedom in Christ. Never force suffering on yourself for attention, this does not glorify God, only yourself! What and where is you primary purpose and love directed too? That is who Christ is, and what His will is the "what". If we are left out on our own, we would never accept His precious gift. Bob stated many times that A.

Hi people, I still trying to start U-Boot from flash on M5282Lite, now I am setting the PC to 0xFFE00400 as said at M5282EVBUM.pdf (M5282EVB flash base is the same to M5282LITE). >From M5282EVBUM.pdf: "If using BDM via a wiggler cable, download first, then start ROM Monitor by pointing the program counter (PC) to 0xFFE00400 and run." But it don't work to M5282LITE, I receive SIGGRANT see below. I found a guy whom got the same problem, but none response to your question: http://mailman.uclinux.org/pipermail/uclinux-dev/2006-March/037661.html I already read a lot of documentation and search about the process to start U-Boot over BDM. Bernhard Kuhn do it, but he used a external pre-loader, I don't want it. Please, someone here already started U-Boot from Flash using GDB/BDM ?

[U-Boot-Users] 8560 based board: CPM I2C, 2 DDR slots
by Dig Dis 15 Dec '06

15 Dec '06

Hello, I have two issues with my MPC8560 based board, which I'm not sure whether they can be answered by the current U-boot: 1. All our I2C components (RTC, ID EEPROM, DDR EEPROM) are connected to the 8560 CPM I2C controller, and not to the 8560 I2C controller. As far as I've seen, U-boot only supports the 8560 hardware I2C controller. Am I correct? If so, it seems that I can port the 82xx I2C driver (which is CPM based) to the 85xx without too much problems, and say add a CONFIG_CPM_I2C flag for this. Do you know if there's any planned support for this before I go ahead with this patch? 2. Our board can have up to two DDR modules, whose slots have different I2C addresses. It seems that spd_sdram doesn't support this (as it only addresses one preconfigured I2C address). Questions are the same: Is this scenario supported in U-boot; If not - is there any planned support for it? Cheers, D.
