I am trying to step through the code of an example of the nRF5_SDK_16.0.0 on the nRF52 DK board.
I downloaded the latest version of Segger Embedded Studio (v4.30c) and I can compile the project for both release and debug.
If I place a break-point on the first line of main (bsp_board_init(BSP_INIT_LEDS); in this case) it looks all normal.
I hit Debug->Go, it programs, but it seems like my break-point is now unavailable. I can hit pause, and see the dissemble. Seems like I can even use the step into button to move somewhat around in the dissembled code. But it fails to link the code with the actual c file somehow.
