How to build a dfu code for a nrf5340

[Nagajans]

I’m trying to build and flash a BLE Mesh DFU application for the nRF5340 DK board, but it isn’t working. I selected the nrf5340dk_nrf5340_cpuapp build target only. Could you please guide me with the correct build procedure for BLE Mesh DFU on the nRF5340?

Hi,

I am afraid Bluetooth Mesh DFU is not yet available for the nRF5340. The reason is we have not yet implemented Bluetooth Mesh support for multi-image DFU, which would be required for supporting both the net core and the app core. While it is possible to get DFU to work for the app core, you will not (as of yet) be able to update the net core.

For details on how to build for Bluetooth Mesh DFU for the app core only, please see the following DevZone ticket: Bluetooth Mesh DFU Target sample failing on nRF5340 DK - "Failed enabling advertiser" error.
