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?
Indeed DCache is the problem.
The old u-boot had CONFIG_SYS_DCACHE_OFF=y.
Thanks, ba_f
