[beagleboard] Need Help In Recovering My Beagel Board C3 rev.

Hold the user button and boot the board with a SD card. In u-boot erase NAND

Thanks For that…but i tried the wy mentioned above…event though the while holding the user button the boot is done from the nand itself…
not able to boot from mmc.

Some people have issues with figuring this out or you could have NAND issues. You can request an RMA and they can do it in about 2 minutes or replace the NAND if needed…
