Facing some trouble replacing a SAMSUNG K9F1208U0M with an ST NAND512W3A. I know it is criminal, but we are still using the 2.4 kernel. The excuse is, it is impossible to port all our code/drivers to 2.6 within the project deadline.
Here is the story. We could successfully install JFFS2 on a Samsung K9F1208U0M NAND chip mounted on a board running linux-2.4.20 on a ppc852 processor. But when we replaced the Samsung chip with an ST NAND512W3A, creating a JFFS2 partition will no longer work. Raw read/write to the device is fine. We could even copy a squashfs image to one of the partitions and mount it without trouble. But whenever we create a JFFS2 partition, mount it, create a file on it, unmount it and mount it again the file goes missing. Attaching a screen-shot of the entire procedure. Note that, the same steps work fine with Samsung chips. Also, neither "eraseall" nor "eraseall --jffs2" is of much help in case of ST. We found some document on the ST site stating what to do to replace a Samsung chip with an ST one. The chips are claimed to be equivalent except that Samsung supports some additional multi-plane commands. But we could not see those commands being used anywhere in the mtd code. Are there anything special to be done for ST NAND chips? Any help will be appreciated.
