[Gta04-owner] Hints for installing QtMoko on recently delivered GTA04 boards

Hi Nikolaus,

since some weeks I'm the proud owner of a GTA04 and yesterday my new 
microSD card arrived as well. So I tried to install QtMoko -
I should have read this post before starting to install it yesterday. 
This would have saved me some time as I ended up restoring u-boot in 
NAND from SD card with a "flash_eraseall /dev/mtd2".

Here's a short description of what happened (with my interpretations - 
don't know if they are accurate):

I followed the instructions at


Trying to boot from SD card after that, I ended up in a reboot loop 
(u-boot menu, then splash screen, no kernel output, reboot) and trying 
to boot from NAND didn't work either (ending up in showing the kernel 
tux, then freezing). As I haven't got a RS232 adapter cable, I couldn't 
debug the boot sequence any further.

After that, I made an SD card with Debian/LXDE root file system from 
unstable and forced a NAND reflash from SD card (and installed the 
system in NAND with the flash-nand script). After that, I could boot 
from SD again. But I could not get QtMoko to boot until now.

The qtmoko-fat-v48.tar.gz has vanished from the download section of 
QtMoko - which is a good thing to prevent problems for new users (as 
me). And the README has been updated. Following the new instruction 
while keeping the actually installed boot files from the debian root 
file system I end up in a reboot loop again (as described above).

Am I doing something wrong? Are there instructions for how to install 
QtMoko from scratch that are known to work with the currently delivered 
batch of GTA04?
