Based on
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwiYq4C71L7sAhURLKwKHSFhDtwQFjAAegQIBBAC&url=https%3A%2F%2Fwww.ti.com%2Flit%2Fpdf%2Fspruij2&usg=AOvVaw0nqU9tbqk5uktRGNNbV4go
(apologies for the ugly Google encoded link) the ONLY PRU instruction with
auto-increment/-decrement is MVIx (Move Register File Indirect) but the
documentation gives one the impression that it allows for incrementing
among the registers, not memory.
Might still be worth the effort of trying it... (Report back if it
works)
