AHi,
I have a bricked GTA02v7 and the Debug Board v3.
I left it for quite some time and now I would like to
revive it.
I think there is a problem with the NAND Bad Block Table.
But also could be I have flashed something wrong in the past.
Anyway.
The phone boots, but the display never activates, and the dfu-utils
doesn't see the attached gta02.
Using the debug board I can see the serial console spitting bootloaders
messages.
The NOR bootloader (I'm quite sure I never flashed it, so it should be
the same shipped with the phone) says:
######### BEGIN console output ################
\
######### END console output ################
Also I cannot get to the uboot prompt (the NOR one or the RAM one), where I
would issue the
various "nand" commands to erase nand and recreate the bad block table.
from wiki this should be the sequence:
nand bad
nand scrub
nand createbbt
dynpart
dynenv set u-boot_env
saveenv
Can anybody help me? I don't know how to get to the prompt of uboot.
Or maybe there is another solution to clear the nand and recreate
the bbt.
Greetings.
Leonardo
I did something like this years and years ago. I broke the screen on my
GTA02 and SDG systems sent me a 'broken' gta02 so I could use the
screen. I played a little with the broken one and found that the bbt
had almost every sector in it.
I was able to rebuild the bbt and I still use that gta02 when my gta04
isn't working well.
Sorry I can't remember the specifics, but I know I was able to do it
without a debug board and almost certainly from the NOR u-boot.
I vaguely remember a u-boot option to switch console output between
serial and USB. If serial (debug board) isn't working for you, maybe
try USB?
Good luck,
Ben
