Trying to enable PRUs and set P8 45,46 to output just to test some IO
toggle using R30 on PRU1

Just saying I would expect these to be set to 0x05 instead of 0x00,
Stranger yet, I'm sure there is some kind of non-obvious reason that in the
overlay file, you reference the pin as offset 0x0a0/0x0a4 when their real
offsets are 0x44310800... wait, i see it there.. nevermind.
anyway should pins be showing the value of 8 instead of 5?
