RPI4 Raspbian 64 bit & LinuxCNC

try isolcpus=2,3 as well

when i run cat /sys/devices/system/cpu/isolated
it returns: 1-3

should it be changed to 2-3?
newbie question: where/how does one change that setting?

elovalvo, please see the attachments for the hal and ini files

thanks!

As a first step, can you try with rx-usecs set to 0?

this might've done the trick--i've run the gcode through 3 times in a row without the "error finishing read" popping up again, although i did have a couple of following errors show up...   

i'll run it a few more times, but this seems to have been a big improvement, thank you!

You might check this for following errors:

interesting--so, for reasons i don't understand, my rpi 4 doesn't seem to find my mesa board when wifi is on, so i have to disable it when
running linuxcnc, so any of the following errors have been happening when disconnected from the internet...

that being said, i did the ntp install and verified its running and will run my gcode again (without internet)...

can anyone tell me how to set the rpi 4 to allow both wifi and ethernet simultaneously?

thanks!
