Why are you trying to compile the ch32v003fun example using the RISC-V Linux toolchain rather than the RISC-V bare-metal toolchain?

[Plaque-fcc]

Why are you trying to compile the ch32v003fun example using the RISC-V Linux toolchain rather than the RISC-V bare-metal toolchain?

I am new and had no specific intention to prefer one instead of the other. All I did was I followed the instructions provided with the project.

What should I additionally change or set up?

[TommyMurphyTM1234]

You should use the RISC-V bare-metal toolchain:

• https://github.com/cnlohr/ch32v003fun?tab=readme-ov-file#getting-started
  • https://github.com/cnlohr/ch32v003fun/wiki/Installation

Thanks so much, by bad, I didn't evaluate the situation right. And yes, most of the time environments at least complain when don't find required means. Seems like the compiler in my case totally doesn't do the job.

Building the proper toolchain, expect it to solve this issue.

[TommyMurphyTM1234]

You can probably use the latest xPack binary toolchain to avoid having to build your own...
