SDK 2.0 for ls1043ardb failed to recognize NOR flash on kernel start up

[hoanguyen]

I rebuilt sdk 2.0 for the ls1043ardb without any change. I noticed that the NOR flash was not recognized as follows:

[    0.232235] scsi host0: ahci-qoriq

[    0.235739] ata1: SATA max UDMA/133 mmio [mem 0x03200000-0x0320ffff] port 0x100 irq 30

[    0.245089] of-flash 60000000.nor: do_map_probe() failed for type cfi_probe

[    0.252104] of-flash 60000000.nor: do_map_probe() failed

Executing the following command got:

root@ls1043ardb:~# cat /proc/mtd

dev:    size   erasesize  name

mtd0: 20000000 00020000 "7e800000.flash"

mtd1: 01000000 00010000 "spi0.0"

the entire startup log is attached!

Do anyone know how to fix this problem?

thanks,

Hoa

Usually u-boot provides NOR Flash configuration. Linux uses configuration from u-boot.

Is there problem for using NOR Flash under u-boot on your board.

U-boot configuration file is located in the u-boot source folder: /include/configs. This folder contains the .h files for the different boards.

Have a great day,
