[U-Boot] [patch 0/2] Some more USB-OHCI bugfixes [V2]
by Remy Bohmer 01 Feb '10

01 Feb '10

This is version 2 of these series! Only patch 1 of 2 has changed, some pedantic Coding Style issues updated that were not detected by Linux/scripts/checkpatch.pl. The USB OHCI init procedure sets the maximum message length the wrong way. A max of 64 bits should not be done by writing '64' in maxpacketsize, but '3'. While fixing this problem it turned out that there is more wrong here in this code it turned out that the wrong bits were checked to determine if the pipe was of type PIPE_INTERRUPT. This series fixes those errors also. I made it 2 seperate patches. The 1st of this series is fully tested and correct on at least the AT91SAM9261 cores. The 2nd patch, however, is created by search-for-the-same-errors-and-replace. I am not able to test that patch, I do not have the boards, so that needs to be done by others or by review. It is clear that code there is buggy in the first place. These patches require my previous series called 'Improve stability USB memory sticks for the common OHCI USB layer.' to be applied before this series. So they should apply on the u-boot-usb git tree. --> git://git.denx.de/u-boot-usb.git I want to mention also, that everytime I look deeper into this code, I find new bugs. It appears that several parts of this code is written with interrupt handling in mind, while we have no interrupt handling at all. Assumptions are done that a interrupt handler does things asynchronous, causing long loops that have no real use at all... So, no guarantees that _all_ problems are solved by now... --

Hi Stefan, I'm trying to get u-boot 2009.03 on coldfire to boot on flash part M29W128G. I think I am getting hit by this bug in the flash chip http://lists.infradead.org/pipermail/linux-mtd/2008-July/022252.html The debug output is as follows: U-Boot 2009.03dvl-00087-gd53876a-dirty (Apr 09 2009 - 19:00:37) CPU: Freescale ColdFire MCF5270 rev. 1, at 150 MHz Board: Ruggedcom MCF5270 I2C: ready DRAM: 8 MB Top of RAM usable for U-Boot at: 00800000 Reserving 172k for U-Boot at: 007d4000 Reserving 256k for malloc() at: 00794000 Reserving 58 Bytes for Board Info at: 00793fc6 Reserving 56 Bytes for Global Data at: 00793f8e Reserving 64k for boot parameters at: 00783f8e Stack Pointer at: 00783f68 Start relocate of code from ff000400 to 007d4000 Now running in RAM - U-Boot at: 007d4000 FLASH: flash detect cfi fwc addr ff000000 cmd f0 f0f0 16bit x 8 bit fwc addr ff000000 cmd ff ffff 16bit x 8 bit fwc addr ff0000aa cmd 98 9898 16bit x 8 bit is= cmd 51(Q) addr ff000020 is= ff00 5151 [snip] Note that we suffer from the same bug, where QRY is not being setup properly. The notes there offers a remedy by sending ff before f0. (or skipping ff altogether). Am I on the right track here and if so, how can I make the same fix in u-boot?

[U-Boot] u-boot fails to uncompress a "gzip'ed -9" kernel
by N. van Bolhuis 30 Sep '09

30 Sep '09

A certain powerpc 2.6.28 kernel (which is by default compressed with gzip -9) fails to load with u-boot v2008.10. It results in a machine check stop. I'm testing on a MPC8313-RDB. Btw. the linux-2.6.28/arch/powerpc/boot/wrapper script takes care of compressing with "gzip -9". On my host linux pc I'm using gzip 1.3.5 (2002-09-30). If I manually compress that same kernel with "gzip -8" and generate a uImage, it *does* work. As far as I know my start/load memory addresses are ok. If anybody has any clues, please let me know. more details follow. Here's the full output of when the problem occurs: U-Boot 2008.10 (Jan 19 2009 - 12:21:43) MPC83XX Reset Status: Software Hard, External/Internal Soft, External/Internal Hard CPU: e300c3, MPC8313E, Rev: 1.0 at 333.333 MHz, CSB: 166.667 MHz Board: Freescale MPC8313ERDB I2C: ready DRAM: 128 MB Top of RAM usable for U-Boot at: 08000000 Reserving 307k for U-Boot at: 07fb3000 Reserving 520k for malloc() at: 07f31000 Reserving 68 Bytes for Board Info at: 07f30fbc Reserving 104 Bytes for Global Data at: 07f30f54 Stack Pointer at: 07f30f38 New Stack Pointer is: 07f30f38 Now running in RAM - U-Boot at: 07fb3000 FLASH: 8 MB NAND: 32 MiB In: serial Out: serial Err: serial U-Boot relocated to 07fb3000 Net: TSEC0, TSEC1 [PRIME] => run tird Speed: 100, full duplex Using TSEC1 device TFTP from server 10.10.4.142; our IP address is 10.10.77.77 Filename 'uImage'.

I also applied this patch: http://www.mail-archive.com/u-boot@lists.denx.de/msg04544.html it makes no difference either. Using "bzip2 --best" gives: Uncompressing Kernel Image ... BUNZIP2: uncompress or overwrite error -3 - must RESET board to recover Using "bzip2 --fast" works, but it takes a long time for u-boot to uncompress the kernel. What's also strange is that some other 2.6.28 kernels (compressed with gzip -9) do work. I probably have some kind of memory error, I don't see it though. Unfortunately the problem doesn't occur when I start debugging it with a jtag debugger (lauterbach). if anybody has any clues, please let me know.
