Bootloader upgrade

[Paul Eggleton]

Hi there,

I just updated the bootloader on my Neo by doing the following via the USB 
u-boot console (bootloader image was downloaded from 
http://buildhost.openmoko.org/tmp/deploy/images/, as suggested in the 
Neo1973_Phase_0 wiki page):

----------------------------------------
GTA01Bv3 # ext2ls mmc 0
<DIR>       1024 .
ry (de      1024 ..
01Bv3      12288 lost+found
          196252 u-boot-gta01bv3-r3_0_0_1321.bin
        25100288 openmoko-devel-image-fic-gta01.jffs2
GTA01Bv3 # ext2load mmc 0 0x32000000 u-boot-gta01bv3-r3_0_0_1321.bin

NAND write: device 0 offset 0x0, size 0x40000
 262144 bytes written: OK
----------------------------------------

After a short while it powered off by itself (is there a way to disable this? 
it's somewhat annoying). I powered back on to find that the OpenMoko splash 
screen was replaced by a small tux icon and message, and the automatic boot 
did not occur. Powering off and then on again with the aux button held down 
gave me a menu with no option to enable the USB console, only "Boot" 
and "Factory restore". Selecting boot flashes some error messages up on 
screen briefly and then powers down (something about bad magic).

Any suggestions? Was it a bad idea for me to try to do this?

Cheers,
Paul
