Hello,
i have an issue with different U-Boot versions, and i have no clue what's the problem. Maybe someone's got an idea?
Working on Xilinx' ARM Platform i use U-Boot version u-boot-xlnx-xilinx-v14.6.01, and it's all good with that one and even lower versions. But, using u-boot-xlnx-xilinx-v14.7 or higher results in serious CPU errors:
This issue shouldn't be discussed in this mailing list as Simon pointed out. It is related to Xilinx and pretty ancient version.

What is that bootstrap program? Maybe you need to turn off the cache before starting it with the 'dcache off' command?
yes, likely this is a problem. There is one related problem to this which is also in mainline u-boot. When you load stuff from non volatile memories sometimes u-boot does cache flush and sometimes not. I am not sure if all RAW accesses (e.g. MMC, Sata) have cache flush but reading from FS doesn't have it.
I would try what Simon suggested which is disable dcache and also load image via tftp for example.
Thanks, Michal
