How to solve :NAND: Nand ECC error ???

[mikekgr]

Dear friends,
I am suffering from a "NAND: Nand ECC error".
Follow you can find the booting as well as what print command says...
Please instruct me what to do in order to solve the problem (is it hardware problem?)

Thanks

try running 'saveenv' and then 'reset'.
saving the environment variable should fix the ECC errors on the environment variables area.

[mikekgr]

Dear Rabeeh Khoury,
first of all thanks for your answer.
As you suggested me I did saveenv and then reset, but after the reset the result was not successful. I still get: NAND: Nand ECC error

Do you have any other idea/tip to test?

Best Regards,
Mike Kranidis

[Rabeeh Khoury]

Can you please print what 'nand bad' command on u-boot says?

BTW - Is it the original u-boot you got from Global? Or is it burned through openocd?

[Rabeeh Khoury]

I just checked U-Boot env variables, you probably have a messed up u-boot env variables.
For removing the diagnostics thing, you need to set 'run_diag' environment variable to 'no'.

You can do it by running the following on u-boot -

Code:

setenv run_diag no
saveenv

[mikekgr]

Dear Rabeeh Khoury,
thanks for your help. I really appreciate your tries to help me and to solve the problem I have.
Well follow, is the answers for your asked questions:

Can you please print what 'nand bad' command on u-boot says?

BTW - Is it the original u-boot you got from Global? Or is it burned through openocd?

1) {nand bad}
Marvell>> nand bad

Device 0 bad blocks:
  03280000
  18900000

2) Yest it is the original u-boot as I got it from Global

I did the above and the result is the following: (as you can see I have not any error on screen but is not booting and I am almost sure that I need to change the booting command but I am not sure what is the "correct command" in my case...)

Dear Rabeeh Khoury,
does make any sense or help the debugging this error:

The main problem with what you wrote is that -

Code:

setenv bootcmd=nand read.e 0x800000 0x100000 0x400000; bootm 0x800000

won't work because of the '='. Alternatively you should be doing -

Code:

setenv bootcmd 'nand read.e 0x800000 0x100000 0x400000; bootm 0x800000'

Seems that you u-boot factory environment variables are corrupted. Please refer to the following that might help -

Dear Rabeeh Khoury,
yes, you are absolute right, I corrected now again there is something wrong (although the start of booting progress now seems normal) see:

Any idea?
Many thanks

[Rabeeh Khoury]

hmm... looks your kernel is corrupted? (resides in offset 1MB (0x00100000))

how did you get into this situation? maybe if we you can roll back you can understand what happened?

I am not really sure how I got into this situation! The only question is: How can install the ubuntu 9.04 again (I mean the supplied ubuntu with the supplied kernel...). Is there anywhere step by step how to?
Thanks and I really appreciate your endless help

Have a look at:
http://openplug.org/plugforum/index.php?topic=67.msg1452#msg1452

you will need a tftp server, may need to rename one of the files, and the usb detection is flakey. You may need to reset the plug more than once.

If u-boot on NAND is programmed using OpenOCD (which is true during production), you will see NAND: NAND ECC error as OpenOCD somehow doesn't support flashing u-boot with ECC support; thus, 88F6281 SoC BootROM reads u-boot without ECC support.

Easier way to fix this issue - re-write u-boot on NAND using u-boot.  This can be done using

Marvell>> setenv ipaddr <ipaddress>
Marvell>> setenv netmask <subnet mask>
Marvell>> setenv serverip <serverip having tftp support>
Marvell>> bubt <uboot.bin file>
Marvell>> reset

Now, you should see no NAND error message during u-boot boot up, only if run_diag env is set to yes.

Thanks sir. I will try the proposed solution one of these days and I let you know
