Now is working, I can read/write Redboot configuration from a linux
program. Before writing I use the ioctl MEMERASE and erase the whole
RedBoot config block.
Thanks Andrew for your suggestion.

But is /dev/mtd5 like any other device? Or do you need to erase it using
an ioctl call?
I don't know, but maybe you need to find out.
