Sorry, I'm not working with git much - after a few tutorials I'm still not sure how to create a valid pull request. Please check the patch files from this message.

I've added new output to HAL (period_ticks) for testing the ARISC code. It is pin A period in raw timer ticks. Then the hal driver calculates velocity from period output, until about 110kHz when it switches back to frequency. Of course this is rather poor, and we should use method described by PCW. Anyway this code seems to work orangePi H3 (the only board I have).

Successfully patched ;)

Hi All.
Orange Pi + 2E
Armbian Buster mainline based kernel 5.10.y from Armbian site.

Sd card boots fine, then I install the desktop from armbian-config.
I also updated the board firmware from armbian-config

sudo apt-get && update all groovey.

Run the allwincnc installer
All good!
Get Linuxcnc icons on desktop etc
“Reboot system to complete installation”

No go!
System will not boot!

Help please? What am I missing…
CPU speed settings for RT ??

Sometimes my test board fails to reboot (sudo reboot). Only full shutdown helps.

The SBC shuts down just fine. It just won’t start back up…
After running the script and rebooting the device wont boot. I don’t get any boot screen dialog. It’s like it is bricked.
Powercycle does not help either.
Only way to get it to work again is to start again with reflash the SD card.
Which is not the answer because it is excludes allwincnc…

It's possible that new armbian version (uboot + linux) isn't compatible with allwincnc's uboot script (firmware loader). Another possible reason - our version of the kernel (for H3) isn't compatible with Orange Pi Plus 2E board.

You can catch the detailed reason installing allwincnc's components one by one (script by script) with rebooting between the scripts.
git clone https://github.com/allwincnc/installer
cd installer 
./install_kernel.sh
sudo reboot # or shutdown now
./install_fw.sh
sudo reboot # or shutdown now
./install_sys_tweaks.sh
sudo reboot # or shutdown now
./install_linuxcnc.sh
sudo reboot # or shutdown now
./install_drv.sh
sudo reboot # or shutdown now
./install_cfg.sh
sudo reboot # or shutdown now

./install kernel.sh seems to work fine after reboot.
System loads
./install_fw.sh —> reboot

Brick…
Bummer

Mmm, I flashed an image form the mirrors.tuna.tsinghua.edu.cn
(Armbian_21.05.1_Orangepiplus2e_busterxxx) and it works…

Weird.

OK. It's time for the full replacement of uboot script (firmware loader) to the kernel module. Need some time to do that.

On a side note... Would it ever be possible to use some of the other Linuxcnc GUI options?

Specifically qtdragon or Probebasic? or any QTpyVCP types?

I tried, to install them but it seems VTK is not supported in Armbian.
