More learning I *Think* I managed to rebuild the kernel using the 3.8 source and info from here: http://elinux.org/Building_BBB_Kernel changing the dts files in the kernel before the rebuild. But now I am stuck as to how to get the new kernel onto the BBB
Is the only method with TFTP via the serial cable? Or is it possible to do via the uSD card? Running Angstrom on the eMMC currently.
