Brick! Help Me!

[[500mhz]]

I have a problem with gp2x.
At start stops on the green screen with an inscription "loading". At me suspicion on breakage of file system.
At attempt of installation firmware 2.0.0 :
1) boot it is put
2) kernel it is put
3) hangs at a format

What will advise to do?

format take long time, how long did you wait?

 

[[500mhz]]

I waited 1 hour)))

I waited 1 hour)))

And? Unbricking the full filesystem with the older 1.* firmware could take 12 hours .

Give it more then an hour if there are NAND issues, that said, do you have a BoB or serial lead so you can get a log of what is going on?

Unfortunately at me is not present BoB and there is no opportunity to receive log file through serial connections

hmm 2.0.0 you say the last step is formating of SD if i remember it right (would be pretty stupid to put kernel and firmware and then format nand)

read thoroughly and then follow the steps use CAUTION when flashing

Hm, again, sounds like a lot of bad blocks on the NAND.
That's the only reason I encountered that kind problems yet (and about 4 or 5 I got back for a reflash were suffering from that cause).

That's also why it can take up to 12 hours: The more bad blocks, the longer it takes.
Usually, it shouldn't take more than a few minutes.

You need a BoB to fix that, as you can only delete the bad blocks (yet) via JTAG...

how can I use JTAG to delete bad blocks? I've been googling around and found this but never having done anything with JTAG or NAND memory, I must ask, is it THE thing?

There exists a small program which you can run via JTAG, a serial port and a special U-Boot (command line via PC) which erases the as bad blocks markings.

I have it lying around on my harddisk somewhere.
