    1. Thanks for responding
    2. I used the SDK: nRF5_SDK_13.1.0_7ca7556
    3. Here is the sequence: I flashed the softdevice and verified after flashed it using nRFgo Studio, it sees the dev board (PCA10056 + 52840) - The file name is: s132_nrf52_4.0.4_softdevice.hex
    4. Run debugger uvision Keil 5.24.2.0, target: nRF52840_xxAA, IROM1(start/size): 0x22000/0xDE000 RAM (Start/size): 0x20002620/0x3D9E0, optimization set to 0.
    5. Set a break point in application main.c - it never got there but keep on looping (BR here!)
    6. This dev board/chip has 1MB of flash and 256KB RAM and these above settings added up correctly. Do I have to change these IROM and RAM settings? and when?
