Dear All,

                I am new to this STM microcontroller. I started working on with some of the few examples provided in keil 4 .Presently i am working on STM32F217IG controller for which I wrote a small program for just toggling the port pins. The Program which i wrote is compiled and  a Hex file is created. This toggling of the port pins I want to check in Debug Mode. When I an running in Debug mode i am facing a problem with an '' error 65. access Violation no Read Permission '', and i am not able to do debugging. Can any one sort out this problem. Thanks &r Regards Vidya

Information about the toolchain and the underlying OS would be helpful here.

... access Violation no Read Permission ... Under Linux, that could mean that you have no permission to access USB. If this is the case, you can try as root, and if this works, granting you (your user) the required access rights.

Are your debug settings actually downloading the code to the board, or are you ''simulating'' the target. Check the ''Debug'' tab under options.
