LinuxCNC + Orange Pi (allwincnc)

Thanks for the reply.

I forgot to mention that I did try editing both the /boot/armbianEnv.txt and /etc/fstab files to no avail. The UUID in both of those files matches the result of the 'blkid' or "lsblk -O" commands. There is only one UUID in each of those files and it is the same. I also tried generic on the attempted edits and replaced UUID=############### with /dev/sda1. still no boot. The message at failure changes to "ALERT! /dev/sda1 does not exist. Dropping to a shell!"

Still hoping for a solution.

Did some more online research and on the Armbian forum there is talk about this problem occurring because of a switch from i2c to RSB. I'm not even sure if what they are talking about is related to my problem but it sounds like it could be. Frankly the discussion (link) and implementation of the patch (link) are above my head. It apparently rolls back from RSB to i2c. If anyone could point me in the right direction of implementing this patch, I would be more than willing to try to do it and report back.

Are you not updating packages? They don't need to be updated!

I have tried both ways, updating and not updating. So far no luck. I pretty much gave up until my new Orange Pi board arrives. I had the O-Pi in the house to do the backup, but when I couldn't get it to work I just restored the image I already had and put it back to work on the mill. Once the new board comes I'll try again.

Hello, I bought a Orange PI 5 16Gb and I successfully installed (thanks to some users of this forum..) Armbian RT and linuxcnc.
Well, last step missing is connect GPIO to a interface board I self made and it's currently used with a RPI4.
Orange PI5 is much more performant so I would like to use in place of RPI.
With RPI I used the specific driver included in Linuxcnc 2.9 but I don't have an idea on how to do for OPI5.
I read about ARISC driver but seems not updated for OPI5.
Any hints? ARISC seems not included in default Linuxcnc installation, in order to try, what I have to do?

I've tried to install ARISC on OrangePi prime, with newest Armbian and RT-patched kernel, but failed. In fact I also tried to load any program to RISC core (even very simple test program), and that also did not worked - every time I've had a system freeze on boot. I'm afraid, that old methods will not work on new system, and it will require some work to get ARISC driver running again.

ARISC driver is a rather deep hack to a OrangePi, that uses more or less undocumented features of the processor. I don't think it will ever be included to mainline. To install it manually You need a compiled binary for a RISC core and u-boot script both placed in a /boot/ directory on SD card. I can help if You wish to try (I gave up and bought mesa ).
