µVISION 5 Debugger: error 65: access violation at 0x40048100 : no 'write' permission

I am using the µVision Simulator on a FRDM KL25z device.

When I start the simulator via the debugger, I get the following error:

      *** error 65: access violation at 0x40048100 : no 'write' permission

The debugger runs well with the FRDM KL25z device.

How can I configure the simulator to run?

Thanks

  • This is how I got the simulator to work:

    I created a simulator debug initialization file, and added the line:

              MAP 0x40000000, 0x400FFFFF read write

    I then updated the Initialization File: section of the Options for Target debug window, so that it will read my initialization file when it starts the simulator.

    I also commented out the following lines in the system_MKL25Z4.c  file:

       while((MCG->S & MCG_S_IREFST_MASK) == 0x00U) { /* Check that the source of the FLL reference clock is the internal reference clock. */

       }

       while((MCG->S & 0x0CU) != 0x00U) {    /* Wait until output of the FLL is selected */

       }
