Rigado nrf51822 debug session not halting

[matt_b]

Hardware: Rigado BMD-200 B using the nRF51822_xxAB Softdevice: S110_nRF51_8.0.0 Base project: ble_app_hrs_s110_with_dfu_pca10028 Project Device: nRF51922_xxAB Project Target: IROM1: [Start: 0x18000 Size:0x23000]; IRAM1:[Start: 0x20002C00 Size: 0x537F]

My goal is to port the ble app hrs with dfu project from the nrf51422 device to the nrf51822 device. So far the project builds as expected and can be uploaded either via Keil or nRFgo Studio with out error. However, when I start the debug session the session does not stop in main. When I halt the debug session the disassembly window shows the target off "in the weeds" some place.

I looked into some forum posts that seem to concern this issue and so far had no luck:

Help debugging nRF51822

nRF51822 iRAM and iROM settings for S110 SD?

debug session doesn't stop at main

What am I missing when I am converting this project to the nrf51822?

I discovered that if I do not leave the bootloader in flash I am able to properly debug. What could be causing the bootloader to corrupt the app I'm trying to debug?

Have you turned of optimization, i.e. set it to -O0?

This was answered above. Thank you for following up though.

No problem,I was notified that there were changes to the question and I thought you were still experiencing issues. Turns out that it was just another user that edited your answer.
