At least I know the uart clock is not what it should be...Yes overlays can fix the clock, so playing with clock dividers directly won't help you a lot. For the PI5, midi-uart0-pi5 does the job.Still I'm not sure if Os overlays take over and fluctuates the clock, need to learn this part way better to deal with it...
It refuses to accept 38400 as baud...
This is my new Pi4B with Bullseye 64 bit, I managed to reinstall TTymidi and Piscope as I did on the Pi2.
I don't know exactly how to check midi uart5.dtbo is the right one... errh... midi-uart0.dtbo Pi4??
I installed the bullseye ttyimidi from your repo.
I hope with the Pi4B to have better chances at reading out the pins state at least...
too much stress configuring Pi5 Bookworm besides Zynthian...
yes, ther is active midi in going into the Pi4B being sent from the SQ64, Piscope is set to rt and pins are high but flat...
notice the frequency in the terminal...
