Hi Martin, The SAME51-CNANO from Microchip uses a Cortex-M4F core which it licenses from ARM. Yes I would be adapting 'appl/launchpad-arm' (done things like this before). It (SAME51) runs at 120Mhz having 256kb ram and 1024kb flash, it would be a good benchmark against the CH32V307 which should outperform the Cortex-M4F. For me it is knowing that the 32 bit code framework appears to work. The CH32X033/35 runs at 48Mhz which compares to UNO M4 at 48Mhz in performance, from the research I have done generally speaking the RISCV will outperform ARM at the same processor clock rate.
