U-Boot version issue

Hello again,


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 lower 
versions.
But, using u-boot-xlnx-xilinx-v14.7 or higher results in serious CPU 
errors:

uboot> fatload mmc 0 0x00ffffc0 bootstrap.uimage

Unfortunately, the DIFF between v14.6 and v14.7 is 60'000 lines...

Is there any chance to fix that?




Have nice day,
