Flashing

Windows

Copy the ST-LINK utility to the Tools/st-link directory.

make boot_flash
make flash

Linux

Make sure to install the udev rules, so you can flash without root privileges.

st-flash --reset write obj_boot/f00b00t.bin 0x08000000
st-flash --reset write obj_app/drquad.bin 0x08010000

Debugging

GDB may complain that auto-loading has been declined. If this is the case, just create a .gdbinit in your home directory:

$ nano ~/.gdbinit
set auto-load safe-path /

Afterwards,

$ arm-none-eabi-gdb obj_app/drquad32.elf

should do the trick.
