Well, it's been a while huh. Apologies for the delay. I simply used the toolchain provided by the manufacturer and ported it, take a look at the github branch.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
I recently got a SiPeed Maixduino with RISC-V with Kendryte K210 cpu https://kendryte.com/downloads/
Can you give me some pointer on how to port the Espruino to the K210 cpu ??
Thanks
