Hello!
I'm trying to update the bootloader of a nRF52 device OTA. We are using SDK 12.3. The device has our own application flashed, along with what is essentially the bootloader example, and we are able to update the app OTA. However, we're failing to update the bootloader...
We are using the hex of the bootloader, compiled with the correct keys, and without merging the bootloader settings (should we merge them?), and then creating the zip file using the following command
nrfutil pkg generate --hw-version 52 --sd-req 0x8C --sd-id 0x8C --bootloader-version our_version --bootloader our_bootloader.hex --key-file our_key.pem our_new_bl.zip
However, when we try to flash the bootloader using nRF Connect, it fails.
The last part of the log retrieve in nRF Connect states the following:
... [DFU] Notification received from 8ec90001-f315-4f60-9fb8-838830daea50, value (ox): 60-04-0A [DFU] Remote DFU error: OPERATION FAILED
Is it possible to extract any error information from the notification value?
Here is the bootloader log from the same transaction (I added some more prints to help debugging). Notice how it hangs after starting the crc check for the second time.

Could you please help shed some light on this matter? Thanks!
