I try to diagnose the flash from U-Boot. When I e.g. try to read from the
flash I get:
NAND read: device 0 offset 0x1, size 0xfffffff
Skipping bad block 0x00000000
Skipping bad block 0x00020000
Skipping bad block 0x00040000
<cut>
Skipping bad block 0x0ffa0000
Skipping bad block 0x0ffc0000
Skipping bad block 0x0ffe0000
NAND read from offset 10000000 failed -22
0 bytes read: ERROR
-> nand
I am really stuck here, and don't know how to proceed. Is it normal that
the flash can suddenly go totally bad? At one moment in Linux the device
just had a few bad blocks and after a reboot, all went bad. I am really
worried about this issue!
Do I need to replace the device?
Any comments on this is appreciated.
Thanks and regards,
- Lars
