Hi there,

I am trying to follow your tutorial, however I cannot build using the current nightly.

   Compiling stm32-blue-pill-rust v0.3.2 (/home/daniel/Documents/stm32-blue-pill-rust)
error: linking with `rust-lld` failed: exit code: 1

error: Could not compile `stm32-blue-pill-rust`.

To learn more, run the command again with --verbose.

I do not think this is a problem with your workspace, but rather something with rust-lld. Any thoughts?

switching to the gnu linker yields this error.

You can modify .cargo/config to remove those arguments. I don't know what the equivalent are for rust-lld though :disappointed:

Please not that the resulting binary is way too big (1,3M).

I created a pull request (#2) for this bug. Fell free to use my fork until this is merged.
