As a side note, it took 74 seconds to flash. Is it normal or is there something that could be improved somehow? It was way faster with GDB.

We are trying to make the `riscv` ecosystem more flexible by allowing custom, non-standard interrupt sources in [this PR](https://github.com/rust-embedded/riscv/pull/211). There is still some work to be done, but I would...

Hey! any news on this? I'm now trying to compile ROS2 for RISC-V and having this package available for RISC-V would make my life way easier :D

@ziyao233 please, could you open a PR on https://github.com/ros2/Mimick ? Looks like ROS 2 uses that fork

In [`riscv`](https://github.com/rust-embedded/riscv/blob/master/.github/workflows/riscv.yaml) we use `rust-toolchain` with different targets, features, etc. So far, it works pretty fine.

Did you have to check them one by one? I haven't found a "check all" button. Therefore, the "all in one" job is still handy. Also, do you have optional...

Looks good to me!! I'd update the `riscv-rust-quickstart` repo to align it with a RED-V clone for now. I have a couple of RED-V boards, so I can take a...

Thanks for your contribution! LGTM, let's wait for the CI to finish. I guess you also need to change the trap handler routine. Is it OK if I leave the...
