If you want you can try it
But have not yet added checks for needed packages and failure checks yet. I have all packages installed…if you have a nearly basic host system you can report me errors and needed packages.
Just call buildimg.sh as written in README.md
What is missing is at least
- wifi.sh and wmt-tools/firmware for r2
- no hdmi config for r2/r2pro
- Wifi firmware for r64/r3
But you should get a bootable system till linux userspace which you can access via debug-uart and hopefully ssh (wan dhcp,lan-ports bridged with static ip 192.168.1.1/24)
