I have now done some tests on i.MX31 PDK:
- v2013.04 and v2014.04 works
- v2014.07 and "tip of tree as of this mail" does not work
To make it work (both v2014.07 and tip of tree) I only have to change the "ldr pc, _reset" to "b reset". I do not have to apply the nop-part of the patch.
Could you please submit this change as a formal patch to the list? Please Cc Albert Aribaud on it.
I would expect Helmut to create a formal patch then I can test that and add a Tested-by.
The problem is it does not work with only the 'b reset' change on my platform. Should I provide a patch with the nops and the question marks around them? It still could be a toolchain difference, mine is pretty old:
$ arm-angstrom-linux-gnueabi-gcc --version arm-angstrom-linux-gnueabi-gcc (GCC) 4.7.2 Copyright (C) 2012 Free Software Foundation, Inc.
When I objdump the elf file I can see the very same code in cpu_init_crit() as in start.S, whatever that might mean (objdump is from the same toolchain).
On a different note I noticed that I received a warning that the PDK board does not use "generic board", I will try to fix this but I don't know how much work that is and when I can submit a patch.
Just add "#define CONFIG_SYS_GENERIC_BOARD" into the board config file and give it a try.
If it works, please send this patch as well (with Stefano Babic on Cc).
That I can do.
Regards, Magnus
I tested the CONFIG_SYS_GENERIC_BOARD on TT-01 and it works fine.
