Can not finish initial build

[eflukx]

New to Rust, but I surely like the idea to develop an application on the CC3200 with Rust. Exited to find cc3200-rs and can't wait to try it out 😄!

When running ./build.sh I got the following errors (about a dozen, but all similar):

error[E0220]: associated type `Err` not found for `Self`
