yulin Posted January 18, 2023 Share Posted January 18, 2023 Not sure if the rolling release includes the UART dtb yet, but when I build my own image (jammy xfce kernel 5.10.110) I don't have the UART dtbs in /boot/dtb/rockchip/overlay/ . As a result, I couldn't add uart0-m2 to /boot/armbianEnv.txt and get /dev/ttyS0 when I was following the official user manual to enable UART. After some researching I managed to solve this by copying the dtb file from orange pi's official ubuntu image to /boot/overlay-user and enable UART with user_overlays=rk3588-uart0-m2 in armbianEnv.txt . Rebooted and it works. However, I suppose it would be better to include the dts files in kernel patches? I'm posting this because I don't know what's the best practice for this. 0 Quote Link to comment Share on other sites More sharing options...
Efe Çetin Posted January 18, 2023 Share Posted January 18, 2023 I agree with you. Some of PWM, i2c and can DTBs also not included currently. Today or tomorrow i'll create a PR for that. 1 Quote Link to comment Share on other sites More sharing options...
