Howdy folks,
I'm trying to enable the PRUs on my BBB, and I'm struggling to understand what I need to do.
A lot of the information I'm finding out in the wild is outdated, going as far back as kernel version 3.8. I have a fresh install of Archlinux ARM on my board and I'm running kernel 4.18.9-1. I assume things haven't changed overly much from kernel 4.14, but if I need to change to an older version I can.
I've read through this thread and this thread and found the answers from summers to be particularly helpful, but even they are a few months old and rely on older kernels, and most importantly neither one seems to focus on enabling the PRUs to be used as MCUs.
Can anybody help me? Are there resources I've missed? Will I need to revert to an older kernel? Will I need to write a custom device tree blob?
Any help would be greatly appreciated,
