async-red-v

This is (will be) a proof of concept Rust async runtime for the SparkFun RED-V RedBoard

If you have one, you can try this program for yourself.

How to

In order to build and upload the program, you will need Rust (of course), cargo, and platformio with the sifive platform installed. You will also need a rv32imac compiler. Build and upload the program with one of these commands (for debug or release versions):

cargo run

cargo run --release

If it gives you an error about firmware.elf not having any section, re-run the upload command. I have not the time/energy to define a proper custom platform, and this is the only way to have our own build script when using platformio.
