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

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.

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...

Thank u & have nice day,
