This may(?) help
http://pandorawiki.o...ion_to_firmware See the bottom section with the code required in a boot.txt you place on the SD card and select by pressing R on start up, in order to get a console and debug the boot sequence.
Reproduced here :
Debugging broken firmware
If you have a problem booting the firmware, and want to investigate before just replacing (or need to try and rescue some data from the
NAND) you can boot into a console by doing the following: Make a file named
boot.txt in root of SD with this
[2]
Code:
:setenv bootargs ubi.mtd=4 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw rootflags=bulk_read console=tty0 vram=6272K omapfb.vram=0:3000K init=/bin/bashubi part boot && ubifsmount boot && ubifsload 0x80300000 uImage && bootm 0x80300000 && boot
then holding down the right shoulder button on boot and booting from the SD card. (It doesn't require an operating system on the SD card, but it will use the boot configuration specified there). This is a text mode boot to the shell, using the
kernel from the
NAND. This should provide a way of bypassing any broken startup scripts, adding in logging for a normal boot, etc. It does not start the full OS, just a basic shell.
------------------
------------------
Not sure about how to access the NAND though.
Perhaps create an SD Install of the latest HF final rather than Debian (manually as you cant use the SD installer) and in some way that can see it(?)
Hope the first bits of use at least
Good luck.
