Sorry but I have sent this thread as a new thead, so I will intend to send

PD: I have included a "define CONFIG_XILINX_FLASH_START 0xff000000 (not
used)" in my auto_config.in file to avoid an error. I have a COMPACT FLASH
(ScanDisk 2GB) but it cannot be used by uclinux as a Flash Memory. Isn't it?


My best regards
