## make targets for the Black Magic Probe
## See: https://github.com/blacksphere/blackmagic (Black Magic)
## See: https://github.com/blacksphere/blackmagic/wiki/Frequently-Asked-Questions (Black Magic udev rules)
##
## Provides the following targets:
##
## all: Wrapper for the elf binary
## flash: Uses GDB to flash the target via Black Magic
## debug: Flashes the target and allows for debugging using gdb and Black Magic
## debug-tui: Flashes the target and allows for debugging using gdb's TUI and Black Magic
##
