Hi everybody. I designed and made a custom board with AT91SAM3U4E. Then I wrote a simple Blinky program and compiled it with Keil. When I want to download it to microcontroller with ULINK2 I get this error message: "Flash Download failed - "Cortex-M3""
In the output window Keil prompts me "Cannot access memory".
Does anybody know how I can solve this strange problem? Thanks in advance.
