Hi everyone, I've just flashed barebox on my Mini2440. I have 2
questions/issues now

1) When trying to load the kernel from TFTP, everything is ok but when
it's trying to mount the rootfs something is not working, even though
I set the rootdelay param to 5 secs.

2) I tried also the boot from nand and is working just fine, but there
no is auto boot when reseting the board... it just give me the barebox
prompt each time, and if i run from there boot nand it works OK, but
no automaGically. :)

Any suggestions? Thank you very much
