[beagleboard] Re: Problems reading PRU data RAM from host side on beaglebone black

For the pure asm part of this You can look at the FPP PRU code: https://github.com/FalconChristmas/fpp/tree/master/src/pru and the sh scripts in there used to compile the asm.The FPP PRU code is all hand tuned assembly and does NOT use the C runtime/stack at all. Thus, the entire me
