    Hi, guys. I need some help in understanding of usage AR100 (OpenRISC) coprocessor inside H3 SoC for the own real-time tasks. Now i'm using mainline kernel built with RT-PREEMPT patch. I'm using it with Machinekit (LinuxCNC) software to control stepper drivers/motors via GPIO step/dir pulses. But step pulses frequency is too slow (about 17 kHz) because the RT kernel latency is about 30 us. I think we can use the built-in coprocessor for the realtime GPIO toggling. The AR100 and main Cortex-A7 can talk to each other with built-in MSGBox. And the question is - how to launch my own firmware on the AR100 core?
