Should be fixed by #380.
Taken from the LPC user manual:
If P2.10 is sampled low and the watchdog overflow flag is set, the external hardware request to start the ISP command handler is ignored.
ISP is the In-System Programming feature. Since the watchdog wasn't initialized before, whenever the watchdog caused the ARM to reset, it would just ignore the bootloader pin. However, `arm_reset()` uses the watchdog to reset the CPU and get called, for example, by the data abort handler. Thus, after a data abort the node will remain unflashable over the BSL.
