Nothing is building and flashing on dev kit.

[YASH]

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?

and also when i flash the softdevice and then flashing my project, it says:- Error: Flash Download Failed : "Cortex-M0"

Which examples are you using? Which SDK version? How exactly you flash it to target? Only poor answers to poorly formulated questions...;)

Hi Verma. It may look like you are using an example that doesn't require a softdevice. You can try to erase the softdevice before flashing the example. But like endnode said, providing as much relevant information as possible is the key to getting good answers. (e.i Which board, SDK-version, softdevice, code snippets etc.)

SDK 12.2.0, nrf51422, s130, nrfgoStudio,

Although Thanks,i got the solution. Starting address of Flash and RAM were supposed to be changed.
