LinuxCNC + Orange Pi (allwincnc)

thanks ill try

owe this was the link to use from Bari from the last page

"H3 has a Mali400 so try to use the Panfrost/Lima drivers.

You need to run a heatsink and you don't want the CPU core speeds to change/throttle. So you need a good heatsink and to the lock the CPU speed governor at ONE speed."

This is what im running
 
 

No matter what, I always end with joint following error. Fresh install, isolcpus, cpu=idle, max freq locked, governor=performance, default conf filles and the error persists. Tried on AXIS and the TK one.

Someone using the 1GB Orange PI PC with success can upload his current ISO, please? I'm considering some kind of hardware flaw, because I've tried everything... Different armbian versions, iI just can't make this work without throwing joint following errors while running the file.

I perfectly run on OPi ONE Armbian which is the link above! No problem.)))

By run you mean you can open an ngc file and run it from the start to finish or just manually move the axis?

Hi Forks,
I upload the Image clone from what I currently using to below
Feel free to try it if you need it.

I did change the setting below:
Set the CPU speed to max

Axis gui already been modify to suit the 1024 X 700 touch screen by using the method below:

Try to install GPU driver has been replace by the method below, but seem like not working well, system still using the software acceleration.

Notice Issue:
setp arisc.gpio.PG6-pull -1 # pull down PG6 to the GND not fouction correctly.
I can't pull down the input pin for ENCODER which is PG6 AND PG7, so the ENCODER would keep counting when the program start.
If that cause troble to you, remove the parameter from the .HAL file.

O pen browser will lead to realtime error.

Not asking anyone in particular BUT can you post your config files if you are having issues?

.INI and .HAL

Open loop stepping real time errors are all about bad configuration files since there is no closed loop.

Just FYI, the Allwinner devices with the current u-boot have difficulty keeping low latency along with running memory intensive apps such as a browser. The latency test may stay under 70,000 when just running LCNC, but jump to well over 100K when a browser is started. Let us know if you get the real time following errors when you are running LCNC on its own or when you start up other applications such as a browser.

isolcpus, cpu=idle, max freq locked, governor=performance. runs without errors but slower than before takes a minute to open a file in Axis before maybe 15 sec. runs chunks unless i click on dro mode... no problem for me just wonder why the load times are x4 now. but it runs with no errors.

isolcpus, cpu=idle, That mean you set to only use one of your cpu core, other 3 just doing nothing.

I'm not sure "isolcpus, cpu=idle" on this project is a good idea, If there's not anything connent to the base-thread, Why we still need to care about the latency for base-thread?
You will lose much of cpu power that already being weak.
