[U-Boot] Issue with running commands
hi, While testing on hawkboard with the latest commit, i hit an issue of commands not being accepted.
hawkboard > reset Unknown command '�����' - try 'help' hawkboard >
Running git bisect showed that this is caused due to commit 054ea170f271: cmd_mem: cmp: unify size code paths. Has anyone seen this issue -- i don't think this is board/arch specific.

You must have a different kind of problem with your board. Commit 054ea170f271 is only changing the code of common/cmd_mem.c, which is not used in any way by the reset command or by the command handler or so - this cannot be causing such an effect; it could only trigger another problem by changing code size or alignment or such.
Best regards,
Wolfgang Denk

I tried to reproduce this on the calimain board (AM1808 SoC), but without success. The reset command works fine with current mainline u-boot.

Thanks for testing this. This looks to be some kind of an alignment issue on my board, which is getting introduced due to the commit i mentioned. The said commit is not directly responsible for the problem, but it introduces some kind of misalignment. I am looking into this -- at such times i so dearly wish i had a jtag debugger :)

I may be totally off track, but I saw a patch recently 'arm: armv7: add compile option -mno-unaligned-access if available' - I wonder if its related

The SoC on my board uses a armv5 based core(arm926ejs), so this patch won't apply for my board.

Tested on Logic Pd's OMAPL138, and found no issues as you mentioned.
Thx, --Prabhakar Lad

I was trying to debug the issue, and i found different behaviour with different toolchains.
Codesourcery(gcc - 4.5.2, binutils - 2.20.51)
With commit 211e47549b668c7, which is the top of master, i don't hit the issue anymore.
ELDK-5.2(gcc - 4.6.4, binutils - 2.22)
With this toolchain, i never hit the issue. But enabling DEBUG in board.c, i get a hang after nand initialisation. I am not able to use debug messages, as the board starts to boot with inclusion of even a single debug message.
I am not sure now if this is something specific to my board, as i see different results with different toolchains. It'd be great if this change(DEBUG enabled in board.c with an eldk toolchain) can be checked on other boards(preferably davinci boards). Thanks.

Worked with my friend during the last week to figure out the issue. That he had a jtag debugger with him actually helped us track down the issue. The issue was that the board was using the wrong version of the nand_read_page function in spl -- we are supposed to use the page read version with oob read first, while the other version was being used. This resulted in corruptions being introduced in the u-boot image that was being copied from the nand.
