Hi Geoffroy,

I assume you wan to do the update for nRF52840 instead of nRF52832. I believe it should be quite similar, you only need to update the flash location I think.

But first please clarify that you can do DFU update from a PC to a nRF52840 without a problem ?

Have you looked at the DFU_SPI_readme.docx file I provided in the blogpost ?

You don't load the .zip file but you need to unzip the .zip file and use the .bin file. Then you use loadbin application to load the image to a location on the nRF52832 or nRF52840.

The location is hardcoded but you can change it in the DFU master code.
