This sounds very similar to problems I initially had.  Odds are your are
burning you LP NAND with the ECCM (FMR[23]) set incorrectly.  So the NAND
read is failing because it is reading the correct ECC from the wrong
offset, hence making it incorrect and uncorrectable.  Double check that and
see if it helps.

Hi
Thanks for reply.
I changed ECCM bit and it fixed "NAND boot... read failed (ltesr)" 
problem. 
However, now it again stuck after printing transferring control.
It lookes like it is able to copy u-boot image to RAM but not able to run 
from there.
What could be problem in this ?

Thanks
Rupesh

This probably means that the NAND is being read appropriately, but is
not able to run the code from the location to where the data is being
transferred.  To what address is your code being transferred?  Is it a
valid region?

Hi

Thanks for the reply.

I get 
NAN DSPL - U-Boot 1.3.0-S600-Ver1.1 (Aug  8 2009 - 02:24:03) MPC83XX
NAN DSPL - U-Boot 1.3.0-S600-Ver1.1 (Aug  8 2009 - 02:24:03) MPC83XX
Loading from NAND : 
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

I have changes the code like below nand_boot.c 


   char str[5] = { 1 }
 for (ctr = CFG_NAND_PAGE_SIZE / sizeof (unsigned int); ctr; ctr--) {
                                ptr = (char*)src;
                                *(dst++) = *(src++);
        str[0] = *(char*)ptr++;
        str[1] = *(char*)ptr++;
        str[2] = *(char*)ptr++;
        str[3] = *(char*)ptr;
        str[4] = 0;
                                puts(str);

                        }
                }
 
I get the continuos 000000 printing on the console .

I think the boot loader0 is failing to read the nand properly and it is 
readig zero's.
Can u please tell is there something i am missing.

Thanks

Why did you go back to the old BSP u-boot?

We're missing a lot -- the rest of the source to that file, since it's
not part of mainline u-boot.

If you want to try something similar with mainline, the file to look at
is nand_spl/nand_boot_fsl_elbc.c.

I believe that there was a slight issue with reading of the large page flash
with version 1.3.x.  I believe it was reading the wrong oob bytes to check
for bad NAND blocks.  I can't remember when it was fixed, but I know that it
is resolved in the most current u-boot.  Try the most current u-boot and
report back if the issue persists.

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)?

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

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

Dear Rupesh Kumar,

U-Boot 1.3.0 is very old. Please try top of tree (v2009.08-rc1).

page support in the mpc8313erdb BSP is likely broken.

[U-Boot] NAND booting of MPC8313 based Custom board

[Rupesh Kumar]

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
