## Debugging
Connect SWDIO/SWCLK/RST/GND to a programmer such as ST-Link v2.1. Run OpenOCD:
```shell
openocd -f interface/stlink-v2-1.cfg -f target/stm32f4x.cfg
```
You may need to power up the programmer before powering the device.
Leave OpenOCD running. Run the GNU debugger:
```shell
gdb target/thumbv7em-none-eabihf/release/thermostat
(gdb) source openocd.gdb
```
## Flashing
```shell
openocd -f interface/stlink-v2-1.cfg -f target/stm32f4x.cfg -c "program target/thumbv7em-none-eabihf/release/thermostat verify reset;exit"
```
