XC164CM program cannot run under debug mode of uVision3

Owen Senmeis

Hello,

I'm using uVision3 and ULINK to develop programs for XC164CM.

While compiling a program there is a warning:

*** WARNING L5: SECTION LOCATED OUTSIDE CLASS AREA SECTION: ?ND0?DLLMAIN
CLASS: NDATA0

This code is still downloaded into the device, but cannot run in debug mode with this error:

*** error 65: access violation: addr=0x0000C000

The referred line is:

0000C000 0000      ADD      R0,R0

My project uses two CAN interfaces. I don't know if this is the reason.

Best Regards,
Senmeis

    To be honest, at first I didn't think this warning is so important. But the application doesn't work even everything looks fine besides this warning (A CAN message is expected to be transmitted after power up). So I made a change in
    'Options for Target -> Target'
    from
    'Small: 'near' functions and data'
    to
    'HCompact: 'huge' data, 'near' funcs'.
    This time the application works! The warning now is changed to

    *** WARNING L5: SECTION LOCATED OUTSIDE CLASS AREA SECTION: ?HD0?DLLMAIN CLASS: HDATA0

    Could anybody tell me why this setting is so important and if I can ignore this L5 warning?

    Thanks
