November 19, 2025Nov 19 I’m currently using the Armbian build system to generate images for the Orange Pi 5 Plus. To use the PREEMPT_RT kernel, I set the BRANCH to current, and with the PREEMPT_RT configuration on the 6.12 kernel I was able to successfully build the image and boot it. However, in this kernel version there are no dtbo files for peripherals like can0, i2c, etc., so I’m unable to use those interfaces. If I set the BRANCH to vendor, I can use the 6.1 kernel, but in order to use a PREEMPT_RT kernel I need to apply the RT patch. The RT patch currently provided is not compatible with the current BRANCH, so kernel build and image creation fail. My question is: while using the 6.12 current kernel, is there any way to copy and use the dtb and dtbo files from the 6.1 vendor kernel?
November 19, 2025Nov 19 Can you copy those dtbo's to /boot/user-overlays (maybe they will need renaming) Then activate them in armbianEnv.txt? https://docs.armbian.com/User-Guide_Armbian_overlays/
