The rock pi 4 is no longer on the download page? https://www.armbian.com/download/?device_support=Supported&tx_maker=radxa&arch=aarch64 There is no rock pi 4 link any more?

Does the radxa distro have the same performance issue or does it work as expected there? You can download a image here https://github.com/radxa/debos-radxa/releases/tag/20230201-0944 My guess is that armbian is not using the correct GPU driver, and that results in CPU decoding. The device tree in the radxa is different than the one in the armbian distro but I have no idea how to fix it.

Sorry for the delay, and thanks for your help and patience Usual user, I'm not 100% sure My first idea was to look here https://github.com/armbian/linux-rockchip/tree/rockchip-sdk-5.10/arch/arm64/boot/dts/rockchip but that repo does not seem to have a rk3399-rock-4c-plus.dts for some reason. So my guess is that it uses the one in the linux repo? https://raw.githubusercontent.com/torvalds/linux/master/arch/arm64/boot/dts/rockchip/rk3399-rock-4c-plus.dts I managed to dump some content using dtc -I fs -O dts /sys/firmware/devicetree/base I have attached it to the post. From what i can see the armbian has some thermal stuff, but the one from radax has more. device-tree-armbian-bookworm.txt

usual user, not sure I follow 100%, but what I have found is that the rk3399-rock-4c-plus.dts and rk3399.dtsi files in the https://github.com/radxa/kernel/tree/linux-5.10-gen-rkr4.1/arch/arm64/boot/dts/rockchip repo are different than the same files in the linux repo. I'm not sure if both are used or if its just the rk3399-rock-4c-plus.dts Would it be safe to compile armbian with the rk3399-rock-4c-plus.dts from radxa? they use a old version of the linux kernel (4.4 if I remember correctly). If it is could you give me some instruction how I would go about replacing the file locally before building a new image? Edit: it looks like the rk3399-rock-4c-plus.dts uses rk3399.dtsi, rk3399-linux.dtsi and rk3399-t-opp.dtsi

Thanks Werner I ended up building it my self, and it seems to work, is there any place i can create a pull request so that it is included in future builds of armbian? I failed to find where the build target configuration is stored.

Usual user, when I run tmon on the armbian distro I get No thermal zones found, exit my guess is that the needed drivers or configuration is missing in armbian.

Thanks for the response, but from what I can see the 4C and 4C+ have almost the same configuration https://github.com/armbian/build/blob/main/config/boards/rockpi-4c.conf https://github.com/armbian/build/blob/main/config/boards/rockpi-4cplus.csc Why does one get a bookworm distro and not the other one? While I guess I could use the framework to build my self one I would prefer if I could download one from https://fi.mirror.armbian.de/dl/rockpi-4cplus/archive/ what settings need's to be changed for a build to go to the download page?

I ran hwinfo on the distro where things thermal monitoring works as expected and noticed rockchip-thermal: /devices/platform/ff260000.tsadc My guess is that this is the driver that adds the thermal's, but I have no idea what path it points to? Edit: I can confirm that the rockchip-thermal does not exist in armbian, and sadly I have no idea how to add it..

For some reason I'm not allowed to edit the question any more, so I will add additional content I found here instead... I tried to compare the loaded kernel modules of both distros but that didn't give me any information. So next I looked at the device tree using dtc -I fs /sys/firmware/devicetree/base the content has been attached. It has the following rockchip-system-monitor { compatible = "rockchip,system-monitor"; rockchip,polling-delay = <0xc8>; phandle = <0x15e>; rockchip,thermal-zone = "soc-thermal"; }; device-tree-radax-ubuntu.txt

Hi I just installed armbian on my rockpi 4c+ and wanted to check the temperature so I found that I should be able to run cat /etc/armbianmonitor/datasources/soctemp But that just gives the error cat: /etc/armbianmonitor/datasources/soctemp: No such file or directory It seems /etc/armbianmonitor/datasources/soctemp is a link to /sys/devices/virtual/thermal/thermal_zone0/temp but I have no /sys/devices/virtual/thermal/thermal_zone0 directory, under thermal I have ├── cooling_device0 │ ├── cur_state │ ├── max_state │ ├── power │ │ ├── autosuspend_delay_ms │ │ ├── control │ │ ├── runtime_active_time │ │ ├── runtime_status │ │ └── runtime_suspended_time │ ├── stats │ │ ├── reset │ │ ├── time_in_state_ms │ │ ├── total_trans │ │ └── trans_table │ ├── subsystem -> ../../../../class/thermal │ ├── type │ └── uevent └── cooling_device1 ├── cur_state ├── max_state ├── power │ ├── autosuspend_delay_ms │ ├── control │ ├── runtime_active_time │ ├── runtime_status │ └── runtime_suspended_time ├── stats │ ├── reset │ ├── time_in_state_ms │ ├── total_trans │ └── trans_table ├── subsystem -> ../../../../class/thermal ├── type └── uevent Guessing this is a bug? Both cur_state files yield 0 when cat them. https://paste.armbian.com/ekebicased I'm using the Armbian_v22.05.2_Rockpi-4cplus_bullseye_current_6.1.33_minimal.img image It seems I can find the same content under /sys/class/thermal/ as under /sys/devices/virtual/thermal/ I have also tried to install lm-sensors but it fails to find any sensors to read, after that i tried to use a rolling release, but it never fetched a IP, guessing the boot failed, but as I have no micro hdmi adapter I could not check what failed. Edit 2023-06-27 I downloaded the latest ubuntu server image from https://github.com/radxa/debos-radxa/releases/tag/20230201-0944 and there it seems to work, is there someway I can find what driver/process created the thermal_zone? After that I tested the latest armbian ubuntu minimal image, sadly it also lacks the /sys/devices/virtual/thermal/

Hi I found the following page https://www.armbian.com/rockpi4/ but I guess those files are for rock pi 4 and not rock pi 4 c? It has a link to 4 c plus images https://fi.mirror.armbian.de/dl/rockpi-4cplus/archive/ but they only contain bullseye? So are there any plans for rockpi 4 c plus to have a bookworm image? Are there any github pipelines that build them where I could send a pull request? (not that my c or c++ compilation skills are existing but I would be happy to give it a try).
