[U-Boot] i.MX53 SPI NOR
by Thomas Besemer 13 Mar '13

13 Mar '13

I am working with a board derived from mx53loco. We have SPI NOR on ECSPI1, and are using U-Boot u-boot-2013.04-rc1. I appear to be having some trouble mapping the device in correctly. I am able to use 'sf probe 0', and using a logic analyzer, we can see the SPI transaction run correctly to ID the device; the command is sent out, CS remains active, and then we see the device ID stream back. However, the read FIFO for SPI controller always reads zero. I have "debug" enabled in <mxc_spi.c>, as well as many of mine own printf()'s, and the end result shows that read FIFO to be zero after we see the correct transaction on the wire. Does anyone have an example, or tips, of how to map in SPI NOR with this version of U-Boot on i.MX53? Thanks, tom

[U-Boot] [PATCH v1 0/1] Get rid of R_ARM_ABS32 relocation records
by Albert ARIBAUD 13 Mar '13

13 Mar '13

R_ARM_ABS32 relocation records cause symbol references to be zero before relocation, and become correct only after relocation. On the other hand, R_ARM_RELATIVE records make references correct before as well as after relocation. This patch series aims at removing all R_ARM_ABS32 relocations from ARM targets. the main contributor of R_ARM_ABS32 relocations is the support code for linker-lists, aka Linker-Generated Arrays. This is due to the fact that LGA start and end symbols, used for ranging these arrays, are linker- generated symbols, which always relocate as R_ARM_ABS32 even though they are supposed *not* to be absolute. V1 of this patch 'series' fixes LGAs so that start or end symbols are actually compiler-generated, and thus their references are relocated using R_ARM_RELATIVE. This V1 is provided for all to test and make sure that no ill-effect arises from LGA changes; V2 will integrate any feedback on LGAs and also remove any remaining R_ARM_ABS32 relocations. Albert ARIBAUD (1): Refactor linker-generated arrays Makefile | 6 +- arch/arm/cpu/arm920t/ep93xx/u-boot.lds | 2 +- arch/arm/cpu/arm926ejs/mxs/u-boot-spl.lds | 2 +-

[U-Boot] [Question][i.MX6q] Is it possible to configure and use the USB-OTG as EHCI host only?
by Rafał Fabich 13 Mar '13

13 Mar '13

Hi All, I am Rafal and this is my first post here, so I would like to say hello to everyone :) I have been using the Sabrelite board (i.MX6Q) from Boundary Devices for some time and now I have been working on U-Boot. The code I use is based on the mainline U-Boot. The current implementation supports USB Host1 only, but I would like to use OTG configured as host (I do not need support for device mode). I wanted to implemet the lowest layer for the EHCI driver like it is done for Host1 (in fact the offset of the USB controller's registers set is different and few things like GPIOs) but it does not seem to work. The result is that the U-Boot creates the EHCI hub, but no device is detected on Port 1. I am expecting something like "Port 1 Status 503 Change 1" but I get "Port 1 Status 502 Change 0". I suppose it is possible to use USG-OTG instead of Host1 as EHCI host in U-Boot somehow. Is there something I am missing? By the way, the device is connected via special adapter and the power (5V) is provided to it. Kind regards, Rafal

[U-Boot] Upgrading PowerPC 4xx to v2013.01
by tx co 13 Mar '13

13 Mar '13

I've been tasked with porting U-Boot from v1.1.5 to v2013.01 for a custom board based off PPC460SX (AMCC Eiger board which is no longer supported). I'm trying to understand what's going on with my current setup. I'm able to load the u-boot.bin and can see that it's in the correct address location. But I'm running into problems when trying to debug using gdb. After I telnet to my BDI2000, I can reset and see that I'm moving memory locations with "ti" like so: rare>i Core number : 0 Core state : debug mode Debug entry cause : JTAG stop request Current PC : 0xfffffffc Current CR : 0x82ca2e28 Current MSR : 0x00000000 Current LR : 0xfffff18c rare>ti Core number : 0 Core state : debug mode Debug entry cause : single step Current PC : 0xfffff000 Current CR : 0x82ca2e28 Current MSR : 0x00000000 Current LR : 0xfffff18c rare>ti Core number : 0 Core state : debug mode Debug entry cause : single step Current PC : 0xfffff004 Current CR : 0x82ca2e28 Current MSR : 0x00000000 Current LR : 0xfffff18c rare>ti Core number : 0 Core state : debug mode Debug entry cause : single step Current PC : 0xfffff008 Current CR : 0x82ca2e28 Current MSR : 0x00000000 Current LR : 0xfffff18c rare> On the BDI, I've build gdb for the powerpc and added -ggdb as well as -fno-schedule-insns -fno_schedule-insns2 #omit-frame-pointer -g to config.mk. >From gdb I run the following: 1. >dir/powerpc-440-linux-gnu-gdb 2. (gdb) set arch powerpc:common 3. (gdb) file u-boot 4. (gdb) target remote ipaddr:2001 (reset via BDI) 5. s or si My initial step through will get me to "tlbtab_start" in board/dir/init.S. and fail like this: tlbnxt () at start.S:483 483 tlbnxt: addi r4,r4,1 /* Next TLB */ (gdb) s 484 bdnz rsttlb (gdb) s 504 bl tlbtab /* Get tlbtab pointer */ (gdb) s Cannot access memory at address 0x3f (gdb) s tlbtab () at init.S:43 43 tlbtab_start Cannot access memory at address 0xfffff1f8 If I reset via BDI and step through again I'll receive the "Cannot access memory at address " at what seems to be random spots. I'm new to software development, especially at such a low level. Any advice you may have would be greatly appreciated, I feel like I'm just spinning my wheels at this point. Thanks, Greg

[U-Boot] [PATCH v2] env: don't generate callback list entries for SPL
by Scott Wood 13 Mar '13

13 Mar '13

SPL doesn't write to the environment. These list entries prevent the functions from being garbage-collected, even though nothing will look at the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to break due to size limitations and/or unresolved symbols. A static inline function is used to provide a context in which we can consume the callback, and thus avoid unused function warnings.

[U-Boot] Correcting ext4write syntax
by Tom Rini 13 Mar '13

13 Mar '13

Hey all, We have a problem with the syntax of 'ext4write'. For fatload, fatwrite, ext2load and ext4load the format is: command interface device:part system-memory-addr filename But ext4write is: command interface device:part filename system-memory-addr Crap. This has been the published interface since May 2012, so 3 releases going on a fourth. I guess we've got two options: 1) Break and correct the order. 2) Correct the order, add a silent fixup if filename and address are backwards and note we'll remove that in a few releases. Thoughts? -- Tom
