The chip as such is detected. If the DoC is accessed correctly then the flash chip has id 0xA5. This id is not in the table of NAND IDs in the file nand_ids.c. The cvs MTD drivers has 0xA5 assigned to a SAMSUNG 2 GiB chip. But as far as I know the Doc MilPlus 16MB uses a Toshiba flash. Any suggestions what's wrong here. How would I verify that access to the DoC is correct? At which address would I read? and what to expect? If this would work, how do I proceed? I read something about nftl_format? The documents/books I found so far (Building embedded linux; Linux MTD, JFFS Howto ..) mostly concentrate on using some kind of pluggable DOC chips that can be inserted in a computer that has Windows or Linux running. Then everything can be done with some tools. But how really to do it on an embedded linux with a soldered DoC ? -- Ruediger Haertel
