I have a project from 3 years ago (2018) that I'm trying to make a simple update to the application code. The code downloads via the Segger Embedded Studio and runs correctly. However, when I use my release batch file (attached below) and load via nRF Go Studio (same process used 3 years ago), it the application code fails to run. My phone's Bluetooth menu shows a "dfu" device which makes me think the device is stuck in the bootloader and not jumping to the application code. Can someone help me understand why?
More details:
-Our bootloader is custom. I don't recall what is custom about it, but I believe the changes were minimal. Either way, we're still using the exact same bootloader hex image we used 3 years ago.
-The release batch file merges the Application, SoftDevice, and Bootloader together. When I update this file to exclude the Bootloader and then flash via nRF Go Studio, it runs application code correctly.
-I've never used the PC app of nRF Connect before now, but when I do and load our output hex image, it complains about "Overlapping data around address 0x40a24". It complains about anything I build now (App + SD + Boot AND ALSO App + SD), but does NOT complain when I load in our old release HEX image from 3 years ago.
-We're using Rigado 320-00040 module which has nRF52832 onboard
-We're using SoftDevice "s132_nrf52_6.0.0_softdevice.hex"
-Looks like we used SDK 15.0.0...
-Maybe it's due to updated nrfutil tools?
-Here are the Bootloader settings reported by the release batch file:
Bootloader DFU Settings:
* File: boot_setting.hex

The production team is on hold waiting on me to get this released, but I'm stuck here. Please help!!
