Ok, so the problem is really that the MTD layer does not know how to talk to your spi flash. I will not be of much help here, I'm afraid, so I'll advise to find a mailing list closer to the problem... > Seems I quoted text in previous mail which annoyed you. Sorry for > being naive. I hope I will not repeat the same. Well if one reads lots and lots of messages, it is basically important that everybody uses an e-mail style allowing efficient processing.
