[U-Boot] QorIQ P1020 NAND Flash 2k-Page-Size Problem

[Allan Fislor]

Hi all,

I have a custom Freescale QorIQ P1020 board, with a serial NOR Flash (eSPI
bus) and a NAND Flash (eLBC/FCM bus). Im booting from the NOR flash.

The old NAND (512 bytes page size) was working perfectly, so I swapped for
another with 2k bytes page size.

I changed in the config file:

   CONFIG_SYS_NAND_OR_PRELIM: added OR_FCM_PGS option

   CONFIG_SYS_NAND_BLOCK_SIZE: set to (128 * 1024)


But this new NAND flash does not work. If I enter the command "nand
erase.chip", all sectors appears with bad block.

The ID is read correctly (Micron MT29F2G08ABAEAWP):

NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V
8-bit), page size: 2048, OOB size: 64


NAND info also seems OK:

=> nand info

Device 0: nand0, sector size 128 KiB
  Page size      2048 b
  OOB size         64 b
  Erase size   131072 b


I tried to enable "#define CONFIG_SYS_NAND_ONFI_DETECTION", but the command
READ_ID at address 0x20 does not return "ONFI".

I tried U-Boot versions 2014.04 and 2014.07, same problem in both.

Any suggestions/ideas?

Best regards,
