Hi
I am trying to run the blinky.rs file from https://github.com/stm32-rs/stm32f4xx-hal/blob/master/examples/delay-syst-blinky.rs on STM32F439ZI board. I am new to embedded systems and RUST. When I use cargo run I get the following error:
source\repos\f4_t1\src> error[E0463]: can't find crate for testerror[E0463]: can't find crate for test STM32G081KBUx STM32G081KBUx
How do I resolve this?
If you type 'rustc --explain E0463' (as indicated in the error message you posted), it explains the error.
I suspect this may be the culprit:
- The crate is not present at all. If using Cargo, add it to `[dependencies]`
in Cargo.toml.
- The crate is present, but under a different name. If using Cargo, look for
`package = ` under `[dependencies]` in Cargo.toml.
In this case, it seems to not be able to find that crate (and I can't find anything like that in the git link you posted).
Not sure how to help you from here, but maybe that's enough information to keep researching?
test is the name of the crate that is the Rust test harness, which is implicitly used when you run #[test] tests. (It's also sometimes called libtest to distinguish it from other uses of the word.) It's not a Cargo dependency; it's part of the standard library that rustc already knows, like core, alloc, and std are.
If it's not found, that usually means you're trying to cargo test with a target triple that doesn't have std either. It shouldn't be required for cargo run, though.
If you are trying to run #[test] tests, then the answer is that you have to either:
runner command that knows how to take a binary and run it on your target hardware (whether emulated or via attached dev board).The linked repo already has a runner set up in .cargo/config.toml:
[target.thumbv7em-none-eabihf]
runner = 'probe-run --chip STM32F411CEUx'
That should be sufficient for cargo run (but not cargo test).
Consider to report the fix to the upstream project. ( Do more as just saying thank you )
