[U-Boot] Can't start Linux if U-Boot built with CONFIG_WATCHDOG
by Matthew Lear 26 Aug '15

26 Aug '15

Hello all, I've added watchdog support based on U-Boot (git) for the m68k coldfire mcf54455evb platform. I've fed the patch to the maintainer to help in development. However, I am unable to start my m68k w/MMU coldfire Linux kernel from U-Boot if U-Boot is built with CONFIG_WATCHDOG regardless if the watchdog_enable(), watchdog_reset() and watchdog_disable() functions touch hardware or not. I initially thought this was a problem with enabling the watchdog somehow (ie when Linux started, some hw configuration in the device was getting upset or corrupted etc resulting in the failure), but when I commented out the code from the above functions that actually accesses the hw (ie to enable, kick and disable the watchdog timer hw block), Linux is still unable to start. In fact, I don't think Linux actually gets started! That's the problem. If I rebuild the same U-Boot code base with CONFIG_WATCHDOG undefined, Linux can start just fine. As far as I can tell, there are no functional differences in building U-Boot with or without CONFIG_WATCHDOG enabled when the functions above are stubs and do absolutely nothing at all. If I build U-Boot with debug, what I see is as follows: ## Transferring control to Linux (at address 40020000) ... BIV ...and then the board is dead. I occasionally see something like the following from U-Boot: *** Unexpected exception *** Vector Number: 4 Format: 04 Fault Status: 0 PC: 4fdbfdc8 SR: 00002700 SP: 4fd72a64 D0: 00000004 D1: 000003f9 D2: 4fdb4202 D3: 004fa3da D4: 00000000 D5: 4fdc7c8c D6: 122c0034 D7: 4fd82f76 A0: 4033cb98 A1: 4025aa39 A2: 40020000 A3: 4fdbfdc8 A4: 00000000 A5: 4fdc5800 A6: 4fd72afb *** Please Reset Board! *** The 'BIV' is relevant because in my 2.6.29 kernel src arch/m68k/include/asm/bootinfo_mm.h, BOOTINFOV_MAGIC is defined to be 0x4249561A which is BIV^Z. This ascii text is located in the kernel image header info: >From arch/m68k/coldfire/head.S: .section ".text.head","ax" ENTRY(_stext) bras 1f /* Jump over bootinfo version numbers */ .long BOOTINFOV_MAGIC .long 0 And from U-Boot itself: -> md ${loadaddr} 40010000: 27051956 97342d7d 4a54afd5 00300000 '..V.4-}JT...0.. 40010010: 40020000 40020000 8a006fc1 050c0200 @...@.....o..... 40010020: 4c696e75 78204b65 726e656c 20496d61 Linux Kernel Ima 40010030: 67650000 00000000 00000000 00000000 ge.............. 40010040: 60084249 561a0000 00004ef9 40304000 `.BIV.....N.@0@. I suspect that the failure of starting Linux is caused by some mismatch in data structures (or versions there of) shared/copied between Linux and U-Boot and that this data has somehow changed when U-Boot is built with CONFIG_WATCHDOG #defined. However, I can't find any evidence of this in the U-Boot code base. The bras instruction above must be key and I suspect that this is the area causing the problem. Can anybody offer any advice / explanation of what exactly could be going on and why? I wouldn't have expected that defining CONFIG_WATCHDOG would change anything as fundamental as this. Apologies for the cross-post (U-Boot and m68k kernel dev) but I hope to get opinions/feedback/help from both communities. Any assistance very much appreciated indeed. Many thanks, -- Matt

[U-Boot-Users] minimum bdi config to read flash on 85xx
by robert lazarski 28 May '13

28 May '13

Hi all, On our custom 8548 board, we can't read our flash correctly. We have one 1Gb bank of spansion S29GL01GP flash and we get: atum>mdh 0xf8000000 0_f8000000 : f9f7 f9f7 f9f7 f9f7 f9f7 f9f7 f9f7 f9f7 The big problem we have now: is this a hardware issue or a bdi config issue? Aside from the flash we have 1GigaByte of DDR ram. Can anyone help us track our flash issues down to be hardware, config file, or some combination? The hardware guys think the board is fine. We've been deep into the manuals of both the 8548 and the bdi and can't find anything wrong.

[U-Boot] Add new NAND flash
by Matthias Weißer 05 Mar '13

05 Mar '13

Hi I would like to add a new NAND flash type to u-boot and have some problems with it. The type is MT29F16G08CBABA – Page size x8: 4320 bytes (4096 + 224 bytes) – Block size: 256 pages (1024K + 56K bytes) – Plane size: 2 planes x 1024 blocks per plane – Device size: 16Gb: 2048 blocks The NAND subsystem is configured as follows #define CONFIG_NAND_MXC #define CONFIG_NAND_MXC_V1_1 #define CONFIG_MXC_NAND_REGS_BASE (0xBB000000) #define CONFIG_SYS_MAX_NAND_DEVICE 1 #define CONFIG_SYS_NAND_BASE (0xBB000000) #define CONFIG_MXC_NAND_HWECC #define CONFIG_SYS_NAND_LARGEPAGE The NAND is connected (8 bit wide) to an iMX25 which is booting from NOR. So the NAND is only a mass storage device. I am able to read the ID of the chip. 2Ch 48h 04h 46h 85h I then added the following entry to the nand_flash_ids[] table {"NAND 2GiB 3,3V 8-bit", 0x48, 0, 2048, 0, LP_OPTIONS}, Before getting to the u-boot prompt I get the following message: NAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0x48 (Micron NAND 2GiB 3,3V 8-bit) NAND bus width 8 instead 16 bit This is caused by bit 6 in id byte 4 which tells that the device is 16 bit wide organized and the iMX specific part of the NAND system which tells the generic system that the device is connected via a 8 bit bus which is obviously correct as the flash chip only has 8 data lines. Is there anything I am doing wrong here? Thanks, Matthias

[U-Boot] Read-only env variables
by Joe Hershberger 15 Jan '13

15 Jan '13

Hi u-boot, I see u-boot supports readonly serial# and ethaddr, but I have a few other variables that I need to be read-only. I'm planning to implement a generic list of variables that cannot be changed or deleted. I'm interested to know what sort of specification people would find most appropriate. My current thought is to follow the same delimiter as the env itself, i.e. null separated list with double null terminator. This list would then be defined in the board config header. It also seems that you should be able to specify simple access rules for each variable name perhaps using "=<val>" after each var name where <val> could have constants (probably numbers for performance, but could be string literals) to define modes. Right now I'm thinking read-only, create-only, change-default, and change-only (i.e no delete) are the modes that make sense. I'm also interested if anyone would be opposed to simply using this new specification of readonly vars to implement the serial# and ethaddr protection. The CONFIG_HAS_UID is a bit odd... should that be available in general for read-only vars? Comments? Thanks, -Joe

by mateer 22 Oct '12

22 Oct '12

Hi, when i run fw_printenv , its not working..It shows:- fw_printenv: line 1: syntax error: "(" unexpected error... Let me tell you what i did... 1) i copy the u-boot source code from my colleague and copy in my hard disk. 2) After then i set the environment through commnads. the commands which i run are # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm omap3_evm_config # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm 3) After then i go to /tools/env, where i configure the fw_env.config and then run make command. 4) After ruuning the command i got crc32.c and fw_printenv. 5)i copied the fw_printenv into the SD-Card and insert the card into the OMAP3EVM board. 6) after then when i use the command ./fw_printenv it throws the error fw_printenv: line 1: syntax error: "(" unexpected error.. Can u please help me what i have to do... I think i am doing something wrong... -- View this message in context: http://old.nabble.com/fw_printenv-is-not-working-tp29297562p29297562.html Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] [PATCH] Prevent malloc with size 0
by Kostaras Nikolaos 17 Oct '12

17 Oct '12

In case malloc is invoked with requested size 0, this patch will prevent the execution of the allocation algorithm (because it corrupts the data structures) and will return 0 to the caller.
