I dreamed since 2010 to be able to make a custom image, once for all, that I could reflash from my PC but it seemed impossible to do. I am wrong?
$ 0xFFFF -M image.fiasco -u
$ 0xFFFF -m RX-51:2101,2102:1.0:xloader:xloader.bin -m RX-51:2101,2102:1.0:secondary:nolo.bin -m 2.6.28:kernel:zImage -m rootfs -g image.fiasco
