RPI4 - Debian / LinuxCNC / EtherCAT / XFCE

I can set the install script to differentiate between distro versions too, if needed.

This is pretty awesome. Can't wait to try on a VM of BUllseye later today.
Note that the release version in debian are also referred to as 
unstable, testing, stable and oldstable
When a new version is released these roll down.

sid always ==  unstable
currently:
testing == bookworm
stable == bullseye
oldstable == buster

So at the moment there is no difference between bookworm and testing

Ah! Very nearly ready for you to try. The choot build system doesnot set up eth0 correctly so I'm sorting that out. Also seeing if i can add a first boot script to auto set the ethercat conf file with MAC etc. Save a job right?

Just check the comments in ethercat.conf. I think you can use eth0 as well as  the mac address which may be easier.

Might have been wrong. I think
/sys/class/net/eth0/address

contains the mac address. Works on my chromebook which runs bullseye

 

posix / bash has read function

read MAC </sys/class/net/eth0/address
echo $MAC

you beat me to it!

Now how to make a first boot script...

read MAC
write conf
restart services
