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 memory blocks are available to the pru assembly code.
You basically need to get the "ResourceTable.asm" included, set the "main" section text segment, and then pass the right flags to clpru. The results "out" can then be loaded via rproc.
