embassy/examples/boot/application/stm32l4/src/bin/a.rs
Ulf Lilleengen 161d3ce05c Add firmware updater examples to CI
CI was not building the a.rs application due to the requirement of b.bin
having been built first. Add a feature flag to examples so that CI can
build them including a dummy application.

Update a.rs application examples so that they compile again.
