If you look at the printenv ... to my understanding uboot does it on it's own:
x_bootargs=console=ttyS0,115200 mtdparts=orion_nand:1M(u-boot),1M at 1M(second_staw
x_bootcmd_usb=usb start 

but in any case I did that earlier along with fatls to see that the kernel could be seen by uboot.

Yes typo but can't see the kernel loading: no output on serial while kernel initializes things ... so something else is wrong too

fstab on miniroot is ok:
root at darkstar:~# cat /mnt/tmp/etc/fstab 
proc            /proc           proc    defaults        0       0
# tmpfs            /dev/shm         tmpfs       defaults         0   0
/dev/sda1       /boot           vfat    noatime,errors=remount-ro 0       1
/dev/sda2       /               ext2    noatime,errors=remount-ro 0       1
root at darkstar:~#

Does not look any better :-(

What next ?

Does it say invalid fat entry because I've vfat on first partition ?
