Write the system resources over the serial console of a running firmware. A development kit needs this the first time it is flashed, on boards whose runner cannot write resources itself.

```
pbl image_resources --tty /dev/ttyACM0
```

The transfer uses sftool on SF32LB52 boards and PULSE flash imaging elsewhere; `--force-pulse` forces the latter.

## Options

```
pbl image_resources [-h] [-b DIR] [--dry-run] [--tty TTY] [--force-pulse]
```

`--tty TTY`

tty for serial imaging

`--force-pulse`

Force PULSE-based imaging even where sftool would be used
