Now that you pointed it out, I just erased the sdcard to make it mbr and it worked.
Strange thing though, I had the feeling that the image itself would override the partition scheme, no?
Armbian for Rock 3A (unofficial build) with mainline kernel
The image partition type is DOS. It should overwrite the SD card partition type. I’ve made a test:
flash the image to the SD card after changing the partition type by running command like /sbin/parted -s /dev/sdb mklabel gpt. The SD card partition type will be DOS back. Maybe there’s something special on your SD card.
For that one I used macos to generate the image, that could be the reason 
I will add an entry on the wiki to make sure some other people don’t hit this again
@piter75 from armbian has found the root cause: https://forum.armbian.com/topic/12352-orange-pi-4/page/3/#comment-94322
If you use macos to generate the images, make sure you use the gnu utils instead of the macos bsd utils.
brew install coreutils
and add /opt/homebrew/bin to your PATH.
Update 20220626
Armbian has disabled the pwm patch from legacy kernel: https://github.com/armbian/build/pull/3928. To make our pwm fan overlay work, there should be some modification: https://github.com/armbian/build/pull/3935. We have to replace the active to default. So the pwm fan overlay file should be like:
/dts-v1/;
/plugin/;
/ {
compatible = "rockchip,rk3568";
fragment@0 {
target = <&pwm8>;
__overlay__ {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&pwm8m0_pins>;
};
};
};

Any ideas?
Which kernel do you use. What’s your output of uname -a?
Sorry I’ve been away and I don’t have access at the moment:
Linux rock3a 5.18.12-rk35xx #trunk.0071 SMP PREEMPT Fri Jul 15 09:43:22 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux
Updated to supported image instead of using one that I compiled to use AX210 card:

Linux rock-3a 5.19.5-rk35xx #22.08.1 SMP PREEMPT Tue Aug 30 07:09:39 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux
Still getting the same issue.
fan-control service is working:

but the fan is not on and even if i manually push the command it stays off
any ideas would be appreciated
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/start-pwm-fan.sh:
#!/bin/bash
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/start-pwm-fan.sh
3, add /usr/local/bin/start-pwm-fan.sh 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: https://github.com/armbian/build/blob/master/config/kernel/linux-rockchip64-edge.config#L6057
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. https://github.com/armbian/build/blob/master/config/kernel/linux-rockchip64-edge.config#L2662
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?
