Hi,

It seems the hex file is corrupt. There was an issue with merghex before which made it sometimes generate corrupt hex files with overlapping data. Can you try updating to the latest nRF Command Line Tools?

Hi,

The bootloader will not know that you have a valid application unless you also generate and flash the bootloader settings page. So in other words, when you have a system with SoftDevice and bootloader you need to flash 4 hex files (which you can merge beforehand if you like):

SoftDevice
Bootloader
Application
Bootloader settings page

PS: nRFgo Studio is now legacy software and I recommend you use nRF Connect Programmer instead, though that is not related to what you are seeing.
