- Disable incremental compilation. It doesn't work for embedded development. You'll hit nonsensical linker errors if you use it.
$ unset CARGO_INCREMENTAL
- Build the application
# NOTE this command requires `arm-none-eabi-ld` to be in $PATH
$ xargo build --release
- Flash the program
# Launch OpenOCD on a terminal
$ openocd -f interface/stlink-v2-1.cfg -f target/stm32f4x.cfg
# Start a debug session in another terminal
$ arm-none-eabi-gdb target/..
NOTE As of nightly-2017-05-14 or so and cortex-m-quickstart v0.1.6 you
can simply run cargo run or cargo run --example $example to build the
program, and immediately start a debug session. IOW, it lets you omit the
arm-none-eabi-gdb command.
$ cargo run --example hello
> # drops you into a GDB session
