Hi Jerry, thx for answering > After you erase the sector/chip, is it all 0xFF (especially the second > location)? (I expect it is, but it is good to start with the fundamentals.) No, it is not. I would say, the first byte is OK (I don't have the board with me right now). > If so, I would speculate your flash chip configuration isn't right.

The Flash chip is a SIMM with 4 LH28F016SCT chips. When I try to use a 32 bits wide bus, it does not work.
