I read through your README, and it's a lot better than most of the other docs I've found so far!

I must be missing something, because when xargo rustc --target=msp430-none-elf --release is done, there aren't any binaries in the target directory. (xargo appears to have succeeded)

Full run:

$ xargo rustc --target msp430-none-elf --release

@trainman419 I think you forgot to pass --examples flag. or --example=timer2

[chernomor]

@trainman419 I just copy examples/timer.rs to src/main.rs and than build :)

[trainman419]

That worked! Thanks!

(now I'm running into https://github.com/pftbest/msp430-rt/issues/2 on rust-nightly, but that seems like a different issue)
