Upload the firmware to the MCU

cargo xtask mightybuga_bsc example blink # use 'cargo xtask help' for a complete list of options

Set the environment variable UPLOAD_TOOL (default is openocd) to use your prefered tool for uploading the firmware to the flash memory of the MCU:

tools	UPLOAD_TOOL	notes
OpenOCD + STLink-v2 probe	openocd	This is the default.
BlackMagicProbe	blackmagic	BMP_PORT variable to set the device where the BMP is connected (default is /dev/ttyACM0).

Example to use BMP:

export UPLOAD_TOOL=blackmagic
cargo xtask run app hello_world

Use GDB debug

You need runner = "gdb-multiarch -q -x openocd_debug.gdb" in mightybuga_bsc/.cargo/config , then start a openocd instance:

sudo openocd -f openocd.cfg

and:

cargo run
