Yes, I believe it could be a flash config problem. I have tried it but
with no success. I am still having the same behavior. The flash was
written (I'm sure because i can dump and see the ip address
server/mask/gateway) but seems that Redboot don't    take this
configuration from flash at boot up.

I also change it. Should I see the differences at fis list command? I
choose -4 as example and the Redboot config remains at 0x407FF000. It
should be at 0x407FA000. Did i understand the cdl_option right?

Any help is welcome. No excuses, only thanks.
