154TODO: need someone with a Beagleboard C4 to verify these instructions. 155The Beagleboard C4 has NAND, while the xM does not. For the sake of simplicity,
156these instructions assume you have erased the NAND on the C4 so its boot
157behavior matches that of the xM. To do this, issue the following commands from
158the u-boot prompt (note that the unlock may be unecessary depending on the
159version of u-boot installed on your board and only one of the erase commands
160will succeed):
155 161
156Due to the lack of NAND on the xM, the install and boot process varies a bit 162 # nand unlock
157between boards. The C4 can run the x-loader and u-boot binaries from NAND or 163 # nand erase
158the SD, while the xM can only run them from the SD. The following instructions 164 # nand erase.chip
159apply to both the C4 and the xM, but the C4 can skip step 2 (as noted below), 165
160and may require modification of the NAND environment. 166To further tailor these instructions for your board, please refer to the
167documentation at http://www.beagleboard.org.
