Hi John, Thank you for the suggestion.
The reason I had tried that is because I didn't know about it. I've taken a look and noticed that there is no defconfig for the beaglebone black in arch/arm/configs/ Further, there is no uImage in deploy after running the build_kernel script. I think that can be remedied with proper application of mkimage from uboot but I haven't had time to try it yet. I'm concerned that an image built in this manner won 't have the propoer support for the beaglebone black hardware, the prus in particular, do you know if it would or not?
