MPLAB SIM Error with FreeRTOS PIC24 Port

Posted by Wayne Richardson on December 4, 2008
Hi all,

I am having a problem with the port for the PIC24 running under MPLAB. I have got the FreeRTOS downloaded and expanded. I then go to the PIC24_MPLAB directory and bring up the RTOSDemo_PIC24 project and build it. The build goes fine. When I set a breakpoint at the vTaskStartScheduler(); I can run to this line, but when I try to step over or run, I get the following error:
CORE-E0004: Trap due to unimplemented FLASH memory access, occurred from instruction at 0x001d08

Any clues as to what I need to do?
I have also verified this in the dsPIC demo.
I am running the free version of the C30 compiler.

Thanks in advance.
Wayne

This just in simulator or on Explorer 16?

This occurs in the simulator. I don't have an Explorer 16 board. I have developed my own prototype board, and am trying to establish a base port that work in the simulator and then modify this to accommodate my prototype board. However, I can't get the base port "right out of the box" to run in the simulator. I am not sure if I am missing a setting, or if it is the free C30 compiler that is causing me problems.

Thanks in advance,
