So you want to build an embedded Linux system?

It’s unfortunate that there’s not better examples of how to really leverage the TI PRU cores. They’re supremely powerful and can even replace the need for some FPGA implementations, that you can get them in such a cheap chip that also runs Linux is just great. Plus, each iteration of the TI AM-series SoC mostly keep backwards compatibility as the PRU abilities increase (AM18xx->AM335x->AM437x->AM57xx->etc all have PRU and the core concepts of how they work are very similar but the abilities and instruction set does evolve over generations).

Interesting comment about the PRU cores – I’ve not designed TI chips into projects for a long time (lately most projects have been i.MX). Does sound like a neat idea. You’re right though – tooling matters a lot – if stuff is a pain to use, no one will.
