Armbian for Rock 3A (unofficial build) with mainline kernel

I can’t see any problems from your info. Here is what I did to start the fan:
1, install overlay using armbian-add-overlay command just like you did
2, create a shell script /usr/local/bin/

echo 0 > /sys/class/pwm/pwmchip0/export
echo 10000 > /sys/class/pwm/pwmchip0/pwm0/period
echo 3000 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
echo normal > /sys/class/pwm/pwmchip0/pwm0/polarity
echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable

sudo chmod +x /usr/local/bin/
3, add /usr/local/bin/ to /etc/rc.local

yeah the only difference is your fan is working and mine isn’t
it does do the boot spin so its not the fan or power it juts wont work during normal use

rookie error - forgot to attach the cable to the main board

Note: I was seeing the fan run at boot and that was what made me think there was nothing else amiss

all good now though

Thanks for doing this. Armbian still does not support panfrost on 6.0.y kernel. I’m not sure why they are not configuring it in, but they aren’t. This little cpu just isn’t enough to be used with any graphical display without that gpu being used.

Still can’t use this though because wireguard can’t be installed because it requires linux-image-rt-6.0 or something and that won’t install for some reason. Then apt completely breaks because of this, needing to dpkg -r --force-depends wireguard or something. I don’t know, but there are some major incompatibilities with using the apt sources provided.

armbian edge should have panfrost built as module:

I downloaded directly from their site, the debian minimal image and it did not have panfrost. I really don’t want to build a custom image.

Installation might break because it tries to recompile module which already exists in the kernel.

Wireguard works OOB. You don’t need to do anything except configuring it.

Minimal image contains “nothing”, certainly there are no user-space libraries to support Panfrost. Try Jammy Gnome desktop image if you don’t want to build from scratch. Panfrost most likely works OOB.

Well I won’t use Ubuntu so I guess im SOL until Armbian releases a Debian XFCE version.

Armbian is a well maintained build framework. Build it on your own or just enable for next time:

Ok so I’m guessing the 3dsupport flag is what enables panfrost?
Adding this line would be sufficient to enable the build?

2 x yes. Also enable Gnome if you are doing this.

Why Gnome over XFCE? I prefer Gnome, but even with Panfrost wouldn’t this be a little much? RK3568 isn’t top tier.
I’m currently trying to build it now. I’ve had to setup a ubuntu jammy virtual machine and took a while to find the script that was causing the whole build to fail because my download speed wasn’t “fast enough”. (anyone that comes across this, it’s somewhere in the lib folder)

Well the build finished, but Panfrost is not being used. I checked 3dsupport and the final output was showing the flag 3dsupport as well. I’m getting llvm with no hardware acceleration and no panfrost. The build also seems to have defaulted to X11 instead of wayland for gnome, even though the wayland sesion is being chosen at login vs the x11 session.

Also, PCIe does not seem to work correctly. I have an AR9462 (QCNA222) m.2 wifi card. I enabled all ath9k settings in the kernel configuration because this card didn’t work on the Debian minimal image either. It still doesn’t work and is failing with the exact same error in dmesg.

I also enabled the ath9k debug but I’m not sure where to even begin using it. What I can see is that IRQ events are not being properly handled by the kernel. This card works perfectly fine on 2 of my other machines.

The echo 1 > /sys/bus/pci/rescan command does not change anything either. Nothing in dmesg, nothing gets loaded.

I’m currently downloading
instead. It’s from the github in OP I believe.
After install, it works with wayland and panfrost, but the same error for wifi shows up. it’s not handling IRQ properly.

To sum up, building this image for this board has not at all been worth it and does not work correctly and PCIe still needs a lot of work.

Relevance to this thread
PCIe does not work in this build, custom build, or Armbian official build with an AR9462 QCNA222 M.2 WiFi card. This card is the best open source blob-free wifi adapter so should have the highest compatibility, but on this board it doesn’t.

Hi, I hope this will be useful to enable hw 3d on debian bullseye. I think I’ve managed to build mesa with panfrost to enable hw, but need to perform more testing to confirm it. I used the newest image from armbian CLI bullseye with kernel 6.0.
Currently I’m on a clean new install with xfce, but tested earlier with wayland - KDE and GNOME were working fine. All the info and credit is to this thread, I’ve just changed a few lines in order for it to work with debian bullseye and rk3568.

This are the steps:

  1. download mesa 21.3 from github (with upper version I had dependency error for outdated package)
  2. install dependencies: sudo apt install meson ninja-build pkg-config zlib1g-dev libexpat-dev libdrm-dev libunwind-dev libwayland-dev wayland-protocols libwayland-egl-backend-dev libx11-dev libxext-dev libxdamage-dev libx11-xcb-dev python3-pip xcb* libx11-xcb-dev libxcb* libxshmfence* byacc flex libxxf86vm1-dbg libxxf86vm-dev libxrandr-dev libxrandr2 bison valgrind
  3. Additional dependencies: pip3 install setuptools mako
  4. Unzip mesa and cd into it
  5. Now build: mkdir build;
    meson build/ -Dgallium-drivers=lima,panfrost,kmsro,swrast -Dplatforms=x11,auto -Dvulkan-drivers= -Ddri-drivers= -Dllvm=false;
    ninja -C build/; ##(this could take a while)
    sudo ninja -C build/ install;
  6. If everything went fine need to install mesa-utils:
    sudo apt install mesa-utils
    After that check with glxinfo | grep render or glxinfo -B. It should still show software rendering. Reboot the system and check again with glxinfo. It should display this:
    glxinfo -B
    name of display: :0.0
    display: :0 screen: 0
    direct rendering: Yes
    Extended renderer info (GLX_MESA_query_renderer):

GL_OES_fbo_render_mipmap, GL_OES_get_program_binary, GL_OES_gpu_shader5,

Hope this helps someone. I still have to test it and unfortunately watching youtube was still very laggy in chromium. I don’t know if there is any difference and if this build is alright?

(As a side note, after installing mesa first time xfce changed font from the system to white and couldn’t get it back, switched to lxde and still was white theme but at least font was alright. Now xfce is fine but login screen font from text is white. Don’t know why)

Hello and respect
We have made a board with the RK3568 chip and it gives the following error when booting:
please help

DDR Version V1.13 20220218
unknown device

Maybe you have a wrong ddr bin.

I have designed the hardware of this board myself and the schematic is exactly similar to Nano Pi R5S.

How to generate bin file?

Somebody tested NPU on mainline kernel?
I tried, but it doesn’t worked
(latest kernel build config haven’t CONFIG_ROCKCHIP_RKNPU option enabled so it may cause that problem)

rock@rock-3a:~/npu$ cat /usr/src/linux-headers-6.1.50-current-rockchip64/.config | grep CONFIG_ROCKCHIP_RKNPU

I tried to run this test

sudo dpkg -i rknpu2-rk356x_1.5.2-3_arm64.deb
rm rknpu2-rk356x_1.5.2-3_arm64.deb
git clone
cd rknpu2/examples/rknn_yolov5_demo/
chmod +x
cd install/rknn_yolov5_demo_Linux/

Npu is not supported in mainline kernel.
