LinuxCNC + Orange Pi (allwincnc)

I have successfully installed Linuxcnc on Orange pi pc2 H5.
But running in terminal, endless waiting for component 'arisc' to become ready...............
help me out please

Hello Dolence,
Have you tried over H5.
Is arisc working ?

I noticed that you said that RISC cores can be used on H2+, but you did not provide corresponding support ~
The minimum requirement seems to be H3. I already have an orange pi zero（H2+）, now I have to buy an orange pi plus 2 and am on the way...

well I have had no success instaling on H5.  kernel seems to install well but rebooting after install just halts.
Gave up waiting for root file system
ALERT!! UUID=(bunch of characters) does not exist.  Dropping to a  shell
(initramfs) _

very great project. Very much hope to continue development. I'm from China, and the orange pie single-board computer with H3 processing is abundant and easy to buy. It may not be easy to buy in other countries affected by the epidemic.

This project just needs a good kernel and a proper u-boot config.

It's not so much countries outside of China but due to the way the pandemic is being handled in China it can be difficult at times for boards to be shipped from and within China.

 
Hi folks, may I ask? 
I am using an Orange Pi PC and stepper drivers TMC2160, open loop system. Yesterday I got many times joint X or Y or Z following errors. I ran the program, machine milling and suddenly the machine stopped and one of the axes had an extremely big position number. I don't understand why, because I have used this control system for about half a year. (it may have happened to me before but maybe 2-3 times?!) 
And my question is how to solve/fix this problem? I tried changing MIN_FERROR and FERROR but this did not help me. (I am not sure if I did it well)

Machine config files and picture of my control board in attachment.

Thank you Martin.
 

Has the area where the Opi operates suddenly gotten warmer?

Which version Opi are you using? How much RAM?

"one of the axes had an extremely big position number." please clarify this. If this was an error, please post the error.

Hi Bari,
Heatsink on OPi have stable temperature about 40degree celsius.
I am using Orange Pi PC with 2GB RAM.
This suddenly happened to me. And the milled part have dimensions about 40x40mm and my working place is 400x500mm. Picture in attachment. Can it affect Gcode? Because yesterday I was milling some another part and machine worked without errors. And I used same milling speeds. 

Do you have any sort of axis position feedback? Or is this an open-loop stepper system?
