QUESTION

I've got an LPC4088 Development Kit connected to my computer via a Segger J-Link.

It is possible to flash new software to the LPC4088 board, but as soon as I start the Debugger, I get an error message:

Cannot Access Memory

What do I have to do to overcome this error?

CAUSE

Presumably, the Debug configuration is causing the problem.

RESOLUTION

• uncheck: Options For Target-Debug-J-Link Settings-Verify Code Download

MORE INFORMATION
