I thought we disabled the HDM in the first place... it's disabled in my uENv.
"Note that you can access almost as many PRU0 pins (11 out, 10 in) without needing to disable either eMMC or HDMI." Unfortuantely I need both processors. If I could even find two inputs on PRU1 I would just move that core over to it and make PRU0 the talkative one. What's the deal with STC/LFC? Its in the AM18xx instruction list but they talk about depreciating it. If one core could write to the other's R30 it's a wasted cycle but if I could free up the LCD pins and have all of the other PRU's excess pins I could definitely use that.
