LinuxCNC + Orange Pi (allwincnc)

What a pity! Can you give me some suggestions on using this board for development? It's my first time to use this board. I hope I can get some help. I now have an RK3399 board, which is Orange Pi 4B. I don't know if he is feasible.

You just need developer/s that are familiar with u-boot, ARM Linux, LCNC and how to program the Cortex M0 microcontrollers.

I think it's a great ARM SOC for running LCNC with a high speed integrated stepgen, and the boards are available and only ~$60ea. It's a few week project for someone that knows what they are doing. It also has a GPU capable of running a HD display at 30fps.

OK, thank you very much for your suggestions. I don't know how to start. For example, how can I install a real-time kernel on my system to run Linux CNC? I also have an H3 board here. I have his system image. All Linux CNC has been installed and can be used, but it does not meet my requirements. I need a lot of IO ports, which seems to be a little small, so I consider using EtherCAT to realize it. I don't know whether it is feasible.

The most simple way is to use Mesa FPGA cards with a RK3399 boards over Ethernet. How to build RT ARM Linux kernels for RK3399 is beyond the scope of this forum.

EtherCAT discussions are at: www.forum.linuxcnc.org/ethercat

I would like to ask how you installed the RT real-time kernel when using H3 card before? Can you give me some suggestions? I will be very grateful

I think this project started out using Armbian and there was a filesystem image that you could just dd onto an SD-card.
