## 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"
```

**Caveat:** This logging does not flush its output. Doing so would
hang indefinitely if the output is not read by the USB host. Therefore
output will be truncated once buffers are full.
