Nothing is wrong here. As far as I know, the networking in U-boot is not running in background, i.e it's only on/enabled when u-boot itself issues a ping-command, tftp or something similar. > > Another strange thing is the nand driver.

The only i.MX31 NAND driver I've used in U-boot is the one I submitted to the list last year but it was rejected. Other people have sent updated drivers (I think there was a i.MX27 driver posted not long ago), but I haven't tried these. Even so, the CONFIG_SYS_NAND_BASE looks incorrect but I don't know if that's the only problem.
