Hi,

I got this error while I was debugging and tried to read a variable. Can Some one please tell me what the problem is. And if  it is possible to solve it.

 Thanks.

Edit:  the variable is a pointer to a pointer of a struct.

    There is a GEL file associated with your target configuration.  The file is specifying what memory is present on your board and what its properties are.  In this case you are trying to access 0xE9F40B04 on the Data page.  The memory map either doesn't have memory as being defined there or has it as non-readable.

    You can view the memory map when you are in a debug session by going to the Tools menu and selecting Memory Map.  This will open a new view.  In the memory map section you should see tabs for the Program, Data and I/O pages.

    In my case I have an F28027 and I can see there is no memory at 0xE9F40B04 on the data page.  Check and see what it says for your device.

    Regards,
