Hello everybody, I have a RaspberryPi 3b with OpenBSD 7.4 installed on it. Everything is working well except one thing that I am struggling a lot with.
I cannot find what /dev/tty* I can use to establish communication with the PL011 UART (Pin 8 and Pin 10). The main goal of what I am trying to achieve is to have a the RPI to communicate over UART with another device. I used to have Raspbian installed on that RPI before, and this UART interface was reachable either with /dev/ttyS0 or /dev/ttyAMA0. So I had a look at the dmesg output [1] of my OpenBSD 7.4 RPI and the only line I found that might be interresting is the following : pluart0 at simplebus0: rev 2, 16 byte fifo But I failed to find what /dev/* is linked to it. I believe pluart0 is used for the serial console but only when 'set tty com0' is defined in /etc/boot.conf. It is no longer the case for me as I now have 'set tty fb0'. I do not know where else to look but I guess there is a way to make it work since I did the whole installation of OpenBSD 7.4 over UART (booting with arm64/miniroot74.img) using pin 8 and pin 10. Would you please let me know if what I am trying to achieve is possible at that point ? [1] dmesg output => https://fabear.fr/arm_ml/dmesg.txt Thank you in advance for your help. Best regards, Fabien
