Hello, You are also correct. You can't get a chip select active on both NAND and NOR at the same time. The point I was trying to make Is that if you were trying to program the NAND and J4 Was set to the wrong mode (i.e. NOR) the NOR flash may Get corrupted (in my case did get corrupted.) Thanks Rudy
