Can't get Keil to break at Main

[mac]

I have a custom board utilizing an RF51822aa device. To test connectivity to the board I built blinky_s110_pca10028. Using Keil 5.12 I tried to debug the program simply expecting to break in main thus verify I can talk to the M0 on the RF51822. My setup uses, as i mention 5.12 and Keil's ULINK2. When I start debug I can see the download occur, then Keil opens a Disassembly window.

I was expecting to have main.c opened and a break point hit. Instead, I have the Disassembly window open and a pointer to address 0x000114CC. Not sure what address that is.

Any thoughts?

Mac - I'm fairly new to Nordic myself, and have been through the issues you're describing. When I can't break at main, it's either because I didn't have the stack programmed, or in Keil under Project/Options, C/C++ I didn't have the IROM1 and IRAM1 memory correct. I'm not sure what they should be for the PCA10028 - It has more RAM than the older PCA10003 board that I'm using.

To program the stack the easiest thing is make sure you have a current version of nRFgo Studio, the current softdevice stack's hex file. Plug your board into the USB port of you PC, and start nRFgo Studio. Left side of the opening screen is a Device Manager Pain. You should see your board labelled Seggar (s/n on seggar chip). Double click on you board. The large right area of studio's window should have a window with 3 tabs, the left labelled "Program Softdevice" Choose that tab, browse to you S110 hex file. and click program. You should be good to go.
