Yes I checked spi status. There was no problem. I also added Blink module to check if firmware is flashed correctly and working. I too had octopus pro board. But I wanted tmc5160 drivers working so I bought skr3. I can see signals in hal meter, but in GUI I am getting No signals what ever

Don't know the answer to that question.

Linuxcnc is the execution of a number of halfiles by halcmd.
Check /usr/bin/linuxcnc for how it is done, it's a bash script.

You can execute the hal statements in the ec3a.hal file withMaybe you can puzzle something together.

So I attached a schematic with the pinouts in my previous post. I'm interested in learning what the process is for creating the firmware for a situation like mine where I do not have a daughter card. Do I load on of the provided files and modify the pinfile?
