Hi Waldemar, fw_printenv and fw_setenv can act on an ordinary file instead of a device if you want; their config file is normally /etc/fw_env.config . So for example, first you could create an empty 16K file uboot.env: dd if=/dev/zero of=uboot.env bs=1K count=16 then you could configure fw_printenv and fw_setenv to act upon that file by putting the following line in /etc/fw_env.config: uboot.env 0x0000 0x4000 0x4000 I hope that helps, B.R. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
