We use a custom board implementation based on nrf52840 that makes use of a proprietary host transport protocol.
I am trying to implement FOTA using our transport. We can successfully download the app_update.bin file that is created when using NCS to create the boot images.
I would like to confirm that by using the DFU Target Library I can update the image slot and reboot to the new image.
Is there anything special I need in order to do this?
Second question:
The app_update.bin image is downloaded to external flash. Could you possibly provide me with suggestions as to the external flash configuration should I wish to specify the secondary slot for DFU. We are using QSPI with an MX25R6435FM2IL0 flash chip. The image is downloaded to an offset of 0x300000.
Thank you
