List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi! I do software work on a board that is moving from the TE28F128 J3C150 to the TE28F128 J3D75 because the J3C parts are going obsolete. According to the Intel migration guide, the J3D part is a drop in replacement for the J3C with a couple of exceptions, such as a change when reading the block locking configuration identifier codes (J3D uses 0x0000/0x0001 versus J3C using 0xFFFC/0xFFFF) and some minor detail about the Enhanced Configuration Register (ECR). I am using the mtd driver from the 2.4.20 build of Linux and the problem I am seeing with the new flash is I getting IO errors during the write cycle, not as much when using cat /dev/mtd2 >/dev/mtd1 but using the program curl to load images into a mtd partition. Reading partitions and erasing partitions seem to work okay. The timings of the J3D are the same or faster than the J3C, so I don't think it is a chip select configuration issue. I appreciate any insight you all might have. Regards, Ron Kundla
