[U-Boot] NAND booting of MPC8313 based Custom board
Hi all,
I am using u-boot version 1.3.0 included in freescale LTIB released for MPC8313ERDB custom board. I tried NAND booting of MPC8313ERDB board using this u-boot and it worked fine.
Using similar procedure i tried NAND boot on my custom board but it dint work :(
My board has large page NAND where as MPC8313ERDB has small page NAND. I have modified all the parameters required for Large page NAND. It prints initail debug message as shown below and then while copying u-boot code from NAND to DDR it detects NAND blocks as bad block and continuously prints 'B' on Console.
NAND SPL - U-Boot 1.3.0 (Jul 30 2009 - 06:33:05) MPC83XX Loading from NAND : BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
Can any one please tell what could be going wrong? Am i missing something in large page NAND initialization?
thanks Rupesh

Please try the current upstream u-boot rather than the BSP version. Large page support in the mpc8313erdb BSP is likely broken.

Hi, I used latest version of u-boot (U-Boot 2009.08-rc1) for NAND booting of my board. Still, it didn't work. Board starts booting and then says read failed and hangs there. It prints following message on console
"NAND boot... read failed (ltesr)"
I am using 2.1 silicon MPC8313 based custom board with large page NAND.
Can any one tell how shall i proceed for booting successfully from large page NAND ?
Thanks in advance Rupesh

You most likely got an uncorrectable ECC error reading the data; did you also program the image from current u-boot, or are you trying to boot an image written by the old u-boot? There could be a mismatch on ECC layout.
Is your board file overriding FMR with CONFIG_FSL_ELBC_FMR (it should not)?

Dear Rupesh Kumar,
In message OF532B0371.E31EB889-ON65257602.0059777C-65257602.005A0A76@lntemsys.com you wrote:

U-Boot 1.3.0 is very old. Please try top of tree (v2009.08-rc1).
Best regards,
Wolfgang Denk
