Hi,
I am working on programming a bootloader on a NRF52840 DK using a different NRF52840 DK. Currently I have them connected via the debugger and have been successful in programming the application, softdevice and bootloader onto the NRF52840. However, part of my project is wanting to DFUs via UART. I have been testing this by programming the bootloader and softdevice onto the device and do dfu to update the application. However, I have been getting the following error and I do not know how to go about solving this error. Does anyone have any ideas?
$ nrfutil pkg generate --hw-version 52 --sd-req 0xAE --application ble_app --application-version 2 --key-file priv.pem app.zip
$ nrfutil dfu serial -pkg app.zip -p COM3
