Nothing is programmed to nRF51 ?

[Texton]

Hi All,

I've got a nRF51-DK development kit, and I just compiled and downloaded my first example to it through Keil uVision. Problem is that nothing happens when the program should be running. And with good reason, because if I run a debug session the whole disassembly is 0xFFFFFFFF.

What am I doing wrong? When I download the program to the target, it says that 9540 bytes are used? Also, if I look directly at the memory something IS programmed at address 0x18000 and forward?

The chips come from the factory unprogrammed to use any project that expects BLE to work, you first must load the Nordic BLE stack known as the Soft Device Stack. I typically program that onto my development boards using the nRFGO studio program.

When i loaded the softdevice, and after that loaded my program, it says :- Error: Flash Download Failed - "Cortex-Mo". Please help
