Issue with nRF52840 Dongle Recovery Mode

[DavidCarneros]

Hello everyone,

I'm having an issue with my nRF52840 Dongle. I can detect the device with nrfutil device list command, which shows:

> nrfutil device list
DC1D9FD62EC5
Product          Open DFU Bootloader
Ports               /dev/tty.usbmodemDC1D9FD62EC51
Traits              usb, nordicUsb, serialPorts, nordicDfu

However, when I try to recover the device using: 

> nrfutil device recover --serial-number DC1D9FD62EC5
 Failed to recover DC1D9FD62EC5, No plugins support device operation
Error: One or more recover tasks failed:
* DC1D9FD62EC5: No plugins support device operation (NotFound)

I get the error shown above indicating that no plugins support the device operation.

Interestingly, I can successfully upload firmware to the device:

> nrfutil device program --serial-number DC1D9FD62EC5 --firmware app.zip
[00:00:14] ###### 100% [2/2 DC1D9FD62EC5] Programmed

Does anyone know why I can't perform the recovery operation despite being able to program the device? Any suggestions on how to resolve this issue would be greatly appreciated.

Thanks in advance for your help!

Hi,

The Dongle is programmed via its bootloader.

The bootloader does not support the recovery operation.
For that you would need an external debugger.

What do you want to achieve by doing recover?
