It should be ignored: your NAND is not 'ONFI compatible', the datasheet just says that it supports the' ONFI command set', which is not the same :). The trace you're seeing here is just notifying that the core failed to detect an ONFI NAND, which is expected in your case. > [ 0.886068] nand: Could not find valid ONFI parameter page; aborting > [ 0.892571] nand: device found, Manufacturer ID: 0xad, Chip ID: 0xd7 > [ 0.898917] nand: Hynix NAND 4GiB 3,3V 8-bit > [ 0.903198] nand: 4096 MiB, MLC, erase size: 2048 KiB, page size: 8192, > OOB size: 640 > [ 0.911908] Bad block table found at page 524032, version 0x01 > [ 0.918534] Bad block table found at page 523776, version 0x01 > [ 0.972112] 5 ofpart partitions found on MTD device 1c03000.nand > [ 0.978116] Creating 5 MTD partitions on "1c03000.nand": > [ 0.983477] 0x000000000000-0x000000200000 : "boot0" > [ 0.988803] 0x000000200000-0x000000400000 : "boot0-rescue" > [ 0.994692] 0x000000400000-0x000000600000 : "uboot" > [ 0.999944] 0x000000600000-0x000000800000 : "uboot-rescue" > [ 1.005763] 0x000000800000-0x000100000000 : "main" > > > > > -- > > Boris Brezillon, Free Electrons > > Embedded Linux and Kernel engineering > > http://free-electrons.com > > -- Boris Brezillon, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
