Performing USB-DFU to NRF9160 through NRF Connect Programmer app in a board other than Thingy:91

[ubieda]

Hello everyone,

I'd like to perform a DFU through the USB port on my custom NRF9160 board (DFU over UART) using the NRF Connect Programmer App.

I already did the Firmware setup to configure MCUBoot and have seen it working with command-line tools (mcumgr) fine.

My issue here is that I see the Programmer application not enabling the "Write" button even though:
- The Board is connected through USB and in DFU mode
- The MCUBoot checkbox is checked.
- The hex image is loaded.

Here is an image to illustrate better what I mean by "Enable Write button"

I also see this does not happen when you do the same procedure with the Thingy:91.

Could you provide some assistance on what alternatives I have in order to achieve this? 

Thanks in advance!

Try unchecking the MCUboot option, and then click "Read" memory, then "Write" the new FW.  Please advise if this fixes the problem.

Hi Kele,
I did un-check the box for "Enable MCUboot", but all the buttons are greyed-out. Here's a pic of what I see:

Is "Read" enabled? Could you double check by mousing over the button?

Confirmed: it is not enabled.
