I’ve had a missing MIDI IN port for some time now althou’ I get MIDI Thru lights.
Does anyone know what the following might mean?
uart0_pclk not registered
uart0_pclk alias not registered

“MIDI Thru” is completely hardware, aka, it will work without SD card in your RBPi
MIDI-IN is implemented with “ttymidi”, reading raw MIDI data from the RBPi’s UART and flowing jack-MIDI data as a Jack port.
Could you check if “ttymidi” is running?
systemctl status mod-ttymidi
You could also try to get the ttymidi logs with:
journalctl -u mod-ttymidi
Regards,
I have had several incidents of ttymidi becoming inoperable since I updated to Aruk RC1. ttymidi is still running and jack_lsp -c
shows that JACK knows about the port and that it is not routed. Attempting to route it with jack_connect ttymidi:MIDI_in ZynMidiRouter:main_in
gives the error cannot connect client, already connected?
. If I restart the RPi or restart the service with systemctl restart mod-ttymidi
then it starts to work again for some minutes but will fail after a while.
