It's enabled by default. I believe that you have the wires swapped. There's a topic here about it where I also added a overlay to adjust what speed at which temperature. I'm not sure if the overlay is still compatible, but since you've already found the source you can change it accordingly.

There is usually only one or two images built per board. That's enough to make sure it compiles properly. All other combinations can be made DIY with the framework, check documentation. Continous Integration https://en.wikipedia.org/wiki/Continuous_integration

ok , so no special procedure exists. There is only minimal image is accessible for download for bpi pro. Does It mean all other failed or nobody tried to build them? Random images are accessible from archive too. What does "CI" stand for?

Our CI produces automated builds which are published here: https://github.com/armbian/community/releases If a build fails we will notice and fix if it doesn't much effort. Otherwise it's demoted to EOS and autobuilds disabled.

Hello everyone, I flashed the armbian into my tf cand and inserted it into my OrangePi 5 Plus, with my fans inserted to the specific socket on board (2pin, 1.25mm, 5V, PWM3_IR_M1). However, when I booted it, the fans was running constantly instead of controlled by temperature dynamically, like the official OS images that did only the fans running when the temperature over 50 celsius. I wanna know how to configure my OS to enable the temperature-controlled fans like the official images. The offical documents shows: Linux uses the default pwm-fan drivers to control thye fans and the device tree was defined in orange-pi-5.10-rk3588/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5-plus.dts Here is the code: fan: pwm-fan { compatible = "pwm-fan"; #cooling-cells = <2>; pwms = <&pwm3 0 50000 0>; cooling-levels = <0 50 100 150 200 255>; rockchip,temp-trips = < 50000 1 55000 2 60000 3 65000 4 70000 5 >; status = "okay"; }; Here are some descriptions regarding some columns: pwms = <&pwm3 0 50000 0>：The fans use pwm3. cooling-levels = <0 50 100 150 200 > 255>：Used to configure the speed levels (duty cycle of PWM). The number and magnitude of the levels can be customized. 6 levels are configured, with the speed range from 0 to 255. rockchip,temp-trips：Used to configure the correspondence between CPU temperature and fan speed levels. This can be adjusted according to actual needs. In the above configuration, 50°C corresponds to level 1, and 70°C corresponds to level 5. Thank you very much.
