Difficulty Compiling for STM32 #1466

Closed alexshirley closed 1 year ago

alexshirley commented 1 year ago

So a bit of a n00b, but I'm running into troubles creating a new project

Here are my dependencies

[dependencies]
stm32-metapac = "7.0.0"
cortex-m = { version = "0.7.6", features = ["critical-section-single-core"] }
cortex-m-rt = "0.7.1"
cortex-m-semihosting = "0.3.3"
panic-halt = "0.2.0"
embassy-executor = {version = "0.2.0", git = "https://github.com/embassy-rs/embassy", features = ["defmt", "integrated-timers"] }
embassy-time = {version = "0.1.0", git = "https://github.com/embassy-rs/embassy", features = ["defmt", "defmt-timestamp-uptime"] }
embassy-stm32 = {version = "0.1.0", git = "https://github.com/embassy-rs/embassy.git", features = ["defmt","stm32f070cb"]}

My kneejerk reaction is that embassy-stm32 and cortex-m-rt are missing additional dependencies, or some additional toml settings, which I've tried to remediate by pulling them into my dependencies as well. However, I have no idea what seems to be wrong with my current setup.

Quick update:

I decided to switch over to nightly, redownloaded the STM32 v6m compiler, and still got a very similar message, this time with the full context:

I updated

[package]
...
edition = "2021"
...

and that seemed to change something, which seems to indicate that the USB is not getting picked up

I completely removed the edition section, and that seems to have done something

Dirbaio commented 1 year ago

you need edition=2021 because it defaults to resolver=2. Otherwise it's merging dependency features across deps and build-deps. For example, invalid register r0: unknown register fails because it's trying to build ARM ASM for x86, and x86 has no r0.

First, make sure you're using exactly the Rust nightly version that's supported by Embassy. Put this file at the root of your project.

Second, if that still doesn't fix it: Can you change it to back when you were getting the USB-related error? and then please paste

alexshirley commented 1 year ago

Ok, I did put the rust-toolchain at the project root, and re-added the edition=2021, so now I'm back to the USB error
