This is my toy implementation of ChibiOS on a RISC-V processor, the SiFive FE310.
The following was implemented and somewhat working:
- CLINT Interrupts
- Tickless using MTIMECMP
- GPIO
- UART
KarlK90 took over from here and has upstreamed GD32VF103 code to ChibiOS-Contrib.
I'm not planning on pursuing this any further.
