nrf9160: DFU of user application over serial

[kk2mkk]

Hi

I am looking for a ways to perform DFU over serial, surprisingly i dont find any ways except this thread with no answers

https://devzone.nordicsemi.com/f/nordic-q-a/48154/9160---from-bootloader-updating-flashing-new-application-and-modem-firmware---how

This requirement is very critical for product where my device should be capable of performing firmware upgrade over serial.

Team NORDIC can you please elevate this case?

regards

Hi!

You can perform DFU over serial by using MCUBoot, please see the documentation here.

This guide on DevZone explains how you can use MCUBoot to update the application FW on your nRF9160 SiP. The guide focuses on the Thingy:91 but the same steps will work with the DK or a custom board.

Best regards,

Heidi
