Hi,

Same issue as #3297 but the solution there (for vim) does not seem to work for vs code on windows unfortunately.

Here is my setup:

.cargo\config file:

[build]
target = "thumbv7m-none-eabi"

.vscode\settings.json file:

{
    "rust.target": "thumbv7m-none-eabi",
    "rust.all_targets": false
}

src\main.rs file:

#![no_std]
#![no_main]

#[entry]
fn main() -> ! {
  loop {}
}

rust-analyzer version: 0.2.108
vs code version: 1.43.2
operating system: Windows 10
rustc 1.42.0 (b8cedc004 2020-03-09) stable
