Error: W0011-CORE: Access attempt to unimplemented RAM memory.

Hi,
I am writing a project for a PIC32MX450F256L (a processor I know well from previous projects) but it is my first use of the Harmony framework. I am using
MPLAB.X v3.00.02 beta
Harmony c1.04.02
XC32 v1.34
 
I am using the Simulator in MPLAB.X to try out the Harmony code to see what it does but I keep getting an exception occurring with the report:
W0011-CORE: Access attempt to unimplemented RAM memory.
 
I've never seen this before and wonder if it is some effect of the Simulator?
Perhaps the Simulator gets mixed up about how much RAM a particular processor is supposed to have
 
Has anyone else had an error like this?
I haven't tried the code on an actual processor yet so I don't know if the exception would occur on real hardware.
 
regards
PhilipJ

    Have you stepped through the code to the instruction that causes this to see what it thinks it's doing?

    Yes, I have tried , my project isn't very complex but being Harmony based it is calling a lot of code that I didn't write and single stepping through it doesn't really tell me much. I haven't yet found that one line where the exception occurs. I've tried setting breakpoints at different places to see how far it runs without causing the exception but nothing conclusive yet.
     
    My problem is that I don't know if this is my mistake in setting up part of the Harmony framework or something going wrong in the Simulator.

    This is definitely a simulator warning.  Fortunately, you can tell the simulator to break on individual warnings and errors.  Go to the project properties

    May be off-topic but I hadve similar problem with MPLAB SIM v3.00.02-beta with dsPIC33EP512GP504 chip. My case is worse because accessing normal RAM which is allowed in gld file throwing math exception with unasked interrupt. I've rechecked the device memory map and confirmed the address is OK. The same project simulates in MPLAB X v2.35 without an exception.

    Edit: not math but address exception.

    P.S. As workaround I've choose smaller chip same series.

    Hi,
    I have gotten the same warning. Is there an option to break it in command line. I am doing some unit test with MDB.  
    Hence no MPLAB in my situation.
    Link below has no information about this:

    Edit:
    Found option in user guide of MDB, add set line in instruction file as below: 
    ...
     
    set breakoptions.corewarnings Ignore
    Hwtool SIM
    ...
     
    But it seems no effect to the output. Tried with Break/break/ignore. What is missing?

    Try
     
       set warningmessagebreakoptions.W00011_CORE_SIM32_UNIMPLEMENTED_RAMACCESS break
