Is it possible to upload over SWD a valid app so that the DFU can jump onto it ?

[Aurele]

Hello,

I'm very new with the DFU on nordic and I would like to know if it is possible to upload a valid application so that my DFY can jump onto it ?

Thank you in advance,

Best regards,

Aurélien

Hello Aurélien,

Yes, you can "validate" the app by generating a new bootloader settings page with nrfutil:

Hello,

Thank you very much for the reply. Is it possible to do it with Segger Embedded. I guess yes, i just need to call a script before uploader over SWD ?

Regards,

Hello,

Yes, you can create a script and automate this step, please have a look at this thread: https://devzone.nordicsemi.com/f/nordic-q-a/47481/mergehex-equivalent-in-ses/187925#187925
