How to install EtherCAT and linuxcnc on Orange Pi 4B?

I have an Orange Pi 4B which uses rk3399 chip. In this topic, I saw someone install EtherCAT and linuxcnc in raspberry pie. I would like to ask if anyone has experience to guide me to install EtherCAT on Orange Pi. Thank you.

There is no progress at present. I don't know where I should start. I hope you can give me some suggestions

If the Orange is truly Pi compatible, I would start with one of these images
raspi.debian.net/tested-images/
Don't panic if you don't get a  GUI desktip. Just type
sudo tasksel (may not need the sudo)
Then at a terminal prompt try typing:
sudo apt-get install linuxcnc-uspace linux-image-rt-arm64
to install preempt_rt
then:
sudo apt install linuxcnc-uspace
Then to install Ethercat, follow the sticky I have written in the Ethercat section. Watch the notes about installing the correct linux headers. You should be good on latest reports. I have not tried it for a while
Good Luck!
