I was hoping to be able to use the nRF52840 port on the Adafruit nRF52840 Feather (that uses the MDBT50Q module). I managed to successfully compile the .hex file using the attached board file that I based on a combination of the NRF52840DK.py and MDBT42Q.py files.

I don't have the tiny SWD cable on hand, so I was hoping to just use Adafruit's bootloader. I generated a DFU package using
```
adafruit-nrfutil dfu genpkg --dev-type 0x0052 --application espruino_2v09.134_nrf52840.hex dfu-package.zip
```
and then successfully flashed it using
```
adafruit-nrfutil --verbose dfu serial --package dfu-package.zip --port /dev/ttyACM0 -b 115200 --singlebank
```
Unfortunately I can't connect to the board over BLE afterwards, and it also doesn't mount over USB. Any chance that this could work, or should I just bite the bullet and get a J-Link with the right cable?
