Here are instructions for restoring your BeagleBoard Rev C4 bootloader into NAND flash.
Assumptions
-
Your dual-partitioned SD card is /dev/sde. If not, follow the LinuxBootDiskFormat instructions to create one and pay careful attention to the FAT boot partition steps.
-
You mounted your FAT partition to the /media/boot directory
Flash the Bootloader
Follow these steps to flash the bootloader into NAND
$ wget http://github.com/downloads/liquidware/liquidware_beagleboard_linux/Beagle-uboot-nand-7Oct2010.tgz
$ tar xvf Beagle-uboot-nand-7Oct2010.tgz
$ cd Beagle-uboot-nand
$ sudo ./copy_files_to_sd.sh /media/boot #use your mount location
$ sudo umount /dev/sde1 #use your device
$ sudo umount /dev/sde2
Make sure to have a terminal ready and open @ 115200 baud to observe output messages.
Insert the SD card into the BeagleBoard and apply power. The restore should continue automatically without user intervention. Once the uboot restore is complete, your BeagleBoard should boot using the supplied angstrom test image. The output will look similar to the following:
.-------. | | .-. | | |-----.-----.-----.| | .----..-----.-----. | | | __ | ---'| '--.| .-'| | | | | | | | |--- || --'| | | ' | | | | '---'---'--'--'--. |-----''----''--' '-----'-'-'-' -' | '---'

Once complete, use a different SD card with the latest uImage and rootfs. Download ones for the BeagleTouch and extract them to your SD card.
