When I define kernel as 'works' means that it compiles and runs linuxcnc and will drive I/O Even the realtime kernels do not give great performance and this means a fast basethread and software step generation is not really possible. I thought maybe linuxcnc PiCNiC ?, or linuxcnc Raspberry PiCNiC ? as a fork although probably best not to fork as I doubt there is any need, but maybe a good name for interface boards etc.įirst realtime, there is a possibilty hard real time kernel may not be absolutely necessary if I/O is moved off to external hardware and handled properly with large prebuffering. configure -with-threads=posix -with-platform=raspberry -enable-drivers -enable-simulator -enable-run-in-place

Raspberry Pi will run linuxcnc but there are many problems still to overcome, I think maybe raspberry pi could be better in some respects than the beagleboneblack, but still too early to tell for certain. Okay brief revision and I hope a better overview of current state. 14Sep2018 news RPi3BPreemptRT prev version preserved for author
