Hi, I have finished the lathe with ethercat drivers. I'm posting my configuration. I am using a revolver head with asynchronous motor with carousel control. mesa reads the encoder and buttons. the machine is cast in steel.

I am currently working on a machine with two X axes 1500x3000mm, what should I do so that with the incremental encoder it can align the bridge if it moves a little in reset mode.

  Good afternoon, I think I managed to do what you asked me, but without results, still with the same error. Could it be my pyocd installation? I've tried with other versions of Debian, but always the same problem.

Best thing to do is think of an RPi running Linuxcnc as the ECU in an early 2000's car or bike, as long as it works there's no real need to upgrade.
I'd like to be able to count the amount of times I upgraded the ECU on my 1999 Toyota Echo on one hand, but I have all the fingers on each hand

On a normal daily driver or even server kernel upgrades are fine.
The issue in this instance is that the kernel used in the image is particular to the RPi and is custom built.
From playing around with various Arm devices the boards aren't as "generic" as the PC platform. Each Arm processor or SOC has it's own quirks as such. The device tree is a way to let the Linux kernel know which devices are available, device tree overlays are used to further customise the setup.
Then there are custom patches that are used to further "tune" a particular board.
I have 3 main machines at home running Linux, one desktop and laptop running Mint and a server running Ubuntu, kernel upgrades are not an issue on any of these 3.
Obviously I have an RPi5 & 4 for testing Linuxcnc images, so these don't see kernel upgrades unless testing new images.
The Orangepi PC that running my hacked together reflow oven doesn't get upgrades, it works and is left alone, but it does have a custom device tree has I needed some status LEDs and an off button on the front panel from the GPIO header. Now if I was to upgrade this kernel I would also have to rebuild the device tree file to suit.
Whilst the Arm platform is good, it's come along way in 20 years, it's not as generic as the PC platform, it's kinda like pre PC days.......but without the OS software issues.

Try been in the directory where the file is located. Before you run pyocd. Are you able to ping the board. 10.10.10.10 ??
