Hi,
Have you been able to connect with the target at least once? You should verify the following:
- Target processor is properly powered.
- Debug connector from J-Link to target processor is properly mapped, oriented and connected.
- The PC have installed the drivers for J-Link debugger.
- Keil project configuration is properly set for the desired memory, included the related Flash driver file.
Hope this will be useful for you.
Best regards!
/Carlos
