Hot wire to make a C4 boot from MMC or USB.

Hi,

  I have a C4 whose nand is corrupted. Upon booting, I get the message
saying:
"u-boot.bin starting from NAND
ECC failed"

upon using the user(S1) button and trying to boot from MMC, I still am
getting the same error messages.

I tried using the beagle-recovery script from

http://beagleboard.googlegroups.com/web/beagle_recover.tar.bz2

and tried to boot from USB, even that failed. Upon suggestion from a
friend I hot-wired the user button to always boot from MMC, did not
work.

Please help me out to boot and clear the nand.

Thanks in advance.

-Vinay.

Follow the instructions here http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidationv3

Except make sure you format the card as FAT not FAT32. There are cases where FAT32 does not work. This should allow you to boot form the SD card. Then use the erase command to erase the NAND.
