disassembly includes not the user-code

Hi,

I've a very simple small programm, which is stored in an external flash memory connected to NCS0. I'm working with the AT91SAM9263 controller from atmel. The programm is stored in the flash device, but I'm not able to execute the programm. The processor is not able to start the programm.

When I start the debugger, keil starts always in the supervisor mode and not in the user mode. Moreover I couldn't see the c-code between the assembler lines in the disassembly. My small programm only turns on a led. So when I start the debugger and stopp it immediately, the led is on.

I don't know where I have to search for the error. Maybe you could give me some hints.

best regards
John
