For flashing firmware to blank device (without bootloader) use `make flash`,
or `make flash STLINK_VER=v2-1` if using a ST-LINK/V2.1 interface.
You need to have OpenOCD installed.
## Building for debugging and hacking in Emulator (Unix port)
Build the debuggable unix binary so you can attach the gdb or lldb.
This removes optimizations and reduces address space randomizaiton.
Beware that this will significantly bloat the final binary
and the firmware runtime memory limit HEAPSIZE may have to be increased.
```sh
DEBUG_BUILD=1 make build_unix
```
