The xM adds a +faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes +the NAND flash. The beagleboard MACHINE is tested on the following platforms: + + o Beagleboard xM + +TODO: need someone with a Beagleboard C4 to verify these instructions. + +Due to the lack of NAND on the xM, the install and boot process varies a bit +between boards. The C4 can run the x-loader and u-boot binaries from NAND or +the SD, while the xM can only run them from the SD. The following instructions +apply to both the C4 and the xM, but te C4 can skip step 2 (as noted below), +and may require modification of the NAND environment. + + 1.
