I've a TOSHIBA 4KiB page NAND connected to the GPMI. (4KiB + 128 bytes OOB) I tested it using the following, 1) U-boot v2012.04 2) Freescale's U-boot for i.MX6 3) Freescale's Kernel 3.0.15 Result: 0x98 0xAC 0x90 0x26 (Correct) 4) Linux v3.5.4 stable Result: 0x98 0xA8 0x90 0x20 (Incorrect) When I issue a READID command, 1, 2 & 3 gives me correct results, whereas the 3.5.4 version gives me some different result. Any help would be very much appreciated. Regards, Vikram
