NAND: No NAND device found!!!

Hello,
I am currently experiencing some erors with my BeagleBoard
(devkit8000).
I tried to update the filesystem of my board, but I think something
went wrong...

Now when I power on the board, this is what i have on my console :

Texas Instruments X-Loader 1.41
Starting OS Bootloader...
NAND: No NAND device found!!!
0 MiB

And that's all...

So, i Tried to do all, the recovery (USB, UART, and MMC) but it
does'nt seem to work..
I tried to boot from the memory card, but it doesn't want to !
Do you have an idea someone ?

Thanks !

This can be a hardware issue.

With a properly formatted and loaded (with MLO and u-boot) SDcard it
should boot from the card
if you press "user" button during reset.

As such NAND is not mandatory for beagle board to work IMO.

Thank your for your reply, but I'm still stuck.

Well, my SD card is FAT formatted, and I have copy the MLO and u-
boot.bin file on it, but when I try to boot from the SD card (this the
User button pressed), I have this message error :

40W

Does'nt sound good, no ?

u-boot for the not-XM version does not start if NAND is not detected. 100%

1.41 is *really* old, use the MLO from http://www.angstrom-distribution.org/demo/beagleboard/ that is up to date and works.

Thanks for your reply...

Ok, I have tried to use the new MLO on the SD card, but that doesn't
seems to work neither... still the same error message..

If the u-boot for the not-XM version does not start if NAND is not
detected, do I have a way to update the u-boot on my card, or to force
the boot from the sd card without looking at the NAND ??

Thanks in advance !

Am I the only one in this case ??

Stéphane,

are you pressing the “user” button during reset? that is what forces the board to use the bootloaders on the card rather than NAND.

Yes, I am pressing the user button during the reset...
and my card is FAT32 formatted with MLO, u-boot.bin files copied on
it..

Why do you say that so emphatically? It does indeed sound like there
is a problem in his MLO/u-boot, but he should be able to boot from his
SD card. Given that his statement was simply "my SD card is FAT
formatted" leads me to believe he likely has NOT formatted it in the
necessary way. mkcard.sh is probably the easiest way to get a SD card
formatted properly.

FAT32 does not always work. I suggest you format it as FAT16.

Aha! I think Jason was on the right track in his last comment.

Try formatting that first partition with FAT16. You can do this using parted on Linux (on Windows, someone else will have to chime in). Seriously - on rev B and C boards, I have had cards that would not work with FAT32 that worked perfectly with FAT16.

I suggest you use 'mkcard.sh'!

Greetings:

I used mkcard.sh on my Linux desktop to format the SD flash. In
addition to MLO and uBoot, I also had the uImage (Linux kernel) file
in the FAT partition.
