RISC-V-Guide VS ch32v103

I know RISC-V has a been around for several years now and companies like Western Digital use it for their NAS products and even Apple has hired a few RISC-V engineers in the past year. Though, what are other peoples experiences with RISC-V engineering and development? Also, for those that haven't heard of RISC-V here some some helpful Tools, Projects, and Learning Resources.

Useful Tools & Resources for RISC-V development.

A useful set of Tools and Learning for RISC-V.

I found a useful list of Tools, Programs, and Resources for RISC-V. Looks like it covers RISC-V models, RISC-V Operating systems, RISC-V Tools, 5G, and Machine Learning. I thought I'd share it for anyone that's interested. https://github.com/mikeroyal/RISC-V-Guide

WCH CH32V203 (approx. $0.50) with RT-Thread? There are no examples for it on Github but you can use the V307 and V103 repos.: https://github.com/openwch/ch32v103

https://github.com/openwch/ch32v103 and https://github.com/openwch/ch32v307 For those tracking such things (Bruce), they are using Qingke V4F core in '307, V4C in '208, V4B in '203 and V4A in '103 and the older, more dedicated parts like the BLE parts like CH57x and CH58x. Source I know of no other parts using those cores, so they may be focusing on the Chinese market or even an internal brand.
