Strompi3 do not work with Leap15.3 on Pi4
Hello, I have issues to get the Strompi3 working on Leap. It works on on the Debian buster 64bit image -so the hardware is OK so far. I use a Raspberry Pi4 with 4GB, booting from USB. The problem is, that the serial communication via /dev/ttyS0 is not working. I disabled the serial console on the kernel command line and rebuild the initrd. I also changed the /boot/efi/config.txt to have dtoverlay=miniuart-bt enable_uart=1 core_freq=250 in it. But I cannot start the serial communication if I connect via minicom to the /dev/ttyS0 port. Any hints ? Karsten

Not sure whether this applies -- you already specified core_freq=250. But I'm not familiar enough with RPi clocking to tell whether that is enough to prevent it. https://x-tech.online/2022/01/dont-use-dev-ttys0/ Torsten
