I took the ble_app_hrs code and made changes to suit my application (increased number of peripherals, included bonding/pairing, included ble_nus, added code for button, led, etc). But as I keep adding code, at one stage, when I enter debug mode, the program flow does not even come to main. It goes to 0xFFFF FFFE. Following are my memory configs: IROM1: start: 0x1B000 size: 0x25000 IRAM1: start:0x200022D8 size: 0x4FC0. When I make IRAM1 to be 0x200012D8, I can get into main, but after sd_ble_enable, app_ram_base = 0x200022D8 and ram_start = 0x200012D8 and hence the program flow fails at softdevice_enable. I use 32kB RAM nRF51822 and SDK 12.3.0 and soft device s130v2. From my map file, this is my memory consumption:

I have attached my .map file herewith: nrf51422_xxac.map
Before entering main, the program flow goes to SystemInit - If I step through this, it comes out of SystemInit (but never gets into main). But, if I run using F5(short key press for continuous run), the program flow never exits SystemInit. Please advice as how to handle this situation.
