RE: nRF Connect Dektop Application "Enable MCUBoot" button application

Hi Marte,

Thank you for your response.

CDC ACM interface is already integrated in my existing application. The device is able to upgrade using Jlink serial using the mcumanager utility and Over nRF USB using dfu-utils. Both command line utility able to update over serial and USB respectively.

However, as I mentioned earlier in my post, I am more curious about device update/flash using the nRF USB port through the NRF Connect Desktop application. Here are the basic question, I have for the Enable MCUboot and nRF connect desktop application.

1. What is the exact use case for the "Enable MCUboot" button in the nRFProgrammer application?

2. How to perform DFU of USB DFU supported nRF5340 using nRFProgrammer(Part of nRF Connect Desktop application)?

Best Regards,

Neel

Hi Neel Oza,

MCUboot and dfu-util are two different things, and the Programmer app does not use dfu-util. In order to be able to update the device through nRF USB in Programmer you must enable MCUboot in your application instead.

See this example by a colleague of mine for how to get MCUboot over USB: MCUBoot Serial Recovery Sample over USB CDC.

Best regards,

Marte
