I have an Orange Pi 5 pro - with a 256GB M.2 SSD drive - I have kernel 6.115 running . Booting from SD - root is mounted on nvme0n1p1 (the SSD). Armbian 25.8.0-trunk53.-bookworm. I have three issues with this - 1:- no audio out of the 3.5 inch jack. 2: No internal Bluetooth 3. Have to use the SD card for initial boot. PCI is working on that version.
I would like to use the RT-Pre-emptive kernel. It doesn't seem to be available. And the 6.1.2 kernel images do not find the SSD drive at all on orange pi 5 pro.
