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:
uboot> fatload mmc 0 0x00ffffc0 bootstrap.uimage reading bootstrap.uimage 6139968 bytes read in 528 ms (11.1 MiB/s) uboot> go 0x01000000
What is that bootstrap program? Maybe you need to turn off the cache before starting it with the 'dcache off' command?

I checked autoconf.mk of both version, but none uses Thumb mode.
I already posted this in a similar context. In that thread i thought the different platform was the reason for failure. But now i'm convinced it is the U-Boot version making trouble. The platform in the other thread uses a new xilinx U-boot. http://lists.denx.de/pipermail/u-boot/2015-September/228940.html
Now i use the same platform and the same uimage but another U-Boot.
Unfortunately, the DIFF between u-boot-xlnx-xilinx-v14.6 and u-boot-xlnx-xilinx-v14.7 is 60'000 lines...
Why is there a special Xilinx U-Boot? Can this not be removed in favour of upstream?
Thank u & have nice day,
