Hello there, I am have developed new platform for Nuclei RISC-V processor, if you are interested in using it, you can take a look at this issue Add support for Nuclei RISC-V Processor development platform · Issue #3340 · platformio/platformio-core · GitHub.
About Nuclei, please visit this site .
This platform for Nuclei RISC-V processor not only support Nuclei N/NX evaluation core running on the HummingBird FPGA Evaluation Board, also support the first RISC-V MCU GD32VF103, if you have a GD32VF103 evaluation board or HummingBird FPGA Evaluation Board, you can take try with it.
For GD32VF103 evaluation board, we recommend you to use jlink debugger to upload or debug application, it will be much faster than its default gd-link debugger.
Thanks
