Hello,
I have a custom board with 1 i.MX27 microcontroller and 1 Numonyx NAND
256MiB 1,8V 8-bit connected on the nfc port.
I manage to read and write in that nand flash from redboot but not from
Linux which crashes.
I tested with Linux stable 2.6.34.1 + board support modification.
I have tested with and without hw_ecc = 1 and get the same crash at
send_cmd+0x20/0x34.
Could you give me any advise to debug this ?
Best regards,
Alexis RODET
Here is the full console printout from redboot start to seg fault:

I would start with enabling CONFIG_MTD_DEBUG and setting
CONFIG_MTD_DEBUG_VERBOSE=3.

I have set only CONFIG_MTD_DEBUG_VERBOSE=0 with "mxc_nand_command ( ..."
log because others are too noisy.
I got that writing in nand flash crashes Linux for every page address >
0x800. (see log bellow)
Read access is OK as RedBoot partition is well scanned, which is in the
last nand flash page, and all blocks are well scanned during boot (see
attached file).
Is there anything to configure in the platform to allow write access to
bigger nand flash than 4Mb (mine is 256Mb) ?
Best regards,
Alexis RODET
