I have compared with the boot up process of other people. They usually have the CFI recongising but we don't have, i.e. CFI: Found 4*8 device.... We use the on-board flash AMD29LV014B x 4 Bank#0 & Bank#1 Could you please give us a hand to find out why? Thanks and regards, Jimmy Boot Log: physmap flash device: 4000000 at 8000000 CFI: Found no Physically mapped flash device at location zero SC520 CDP flash device: 800000 at 8800000 CFI: Found no SC520CDP Flash Bank #0 device at location zero request_module[jedec]: Root fs not mounted mtd: Giving out device 0 to SC520CDP Flash Bank#0 SC520 CDP flash device: 800000 at 9000000 CFI: Found no SC520CDP Flash Bank #1 device at location zero request_module[jedec]: Root fs not mounted mtd: Giving out device 1 to SC520CDP Flash Bank#1 SC520 CDP flash device: 80000 at 9800000 CFI: Found no SC520CDP DIL Flash device at location zero request_module[jedec]: Root fs not mounted mtd: Giving out device 2 to SC520CDP DIL Flash Compare with the others: SC520CDP Flash Bank #0: Found 4 x8 devices at 0x0 in 32-bit mode Amd/Fujitsu Extended Query Table v1.0 at 0x0040 SC520CDP Flash Bank #0: JEDEC Device ID is 0xC8.
