NRF TOOLKIT + dfu_application.zip

[Perre]

Hi

Want to OTA update my nrf5340

dfu_application.zip is built in my build/zephyr folder.

I try to use this file with the nrf toolkit(nRF Device Firmware Update).

but when issue the update(start) all failed with logg saying, 

content of my zip file

Should I be able to use the zip file without modification and use it in nRF toolkit(android 12) ?

"The build system will automatically place both the application core and the network core update binaries (app_update.bin and net_core_app_update.bin) into a container package named dfu_application.zip. This container package can be used by update tools to pass both images during the simultaneous update of multiple images."

Hello,

Could you share the SDK version you are using? Are you working with Android or iOS? Do you have any logs to share, in order to get a bit more idea on what's happening on the image side? Are you giving "Test and confirm" or "Confirm only" to the image for swapping?

Kind Regards,

Abhijith

Just as info.. issueing the ticket I used connect SDK 2.2.0 version. 

After some struggle I have now upgraded to SDK 2.4.0 and now the DFU works well. 

I changed my .config to get all code compiled on new SDK version(2.4.0). Dont really know exactly what did it. 

Anyway, I am happy!
