CCS/CC2640R2F: ROV error while running example code: Target memory read failed

Tool/software: Code Composer Studio

Hi,

I'm using the CC2640R2F launchpad running SDK 1.50.00.71. When I tried using the ROV, the same error was always occurring even though the application was running correctly:
"Error: java.lang.Exception: Target memory read failed at address: <addr>, length: <len> This read is at an INVALID address according to the application's section map. The application is likely either uninitialized or corrupt."

I have found similar threads regarding this problem but none of the fixes seem to be the solution to my problem.
I built my application around the simple_peripheral example. I tried running an unmodified version of the simple peripheral example, and got this same error (also when I run the host_test example from the same SDK).

Does anyone have a suggested action to overcome this issue?

Thanks in advance,

Gamli

I managed to fix this. If someone else is experiencing this, here is a workaround:

The following lines of code need to be added to the package.xs file (\kernel\tirtos\packages\ti\sysbios\heaps\package.xs)

    function init()
    {
        /* Add HeapMem's primaryHeap addresses range to ROV's memory sections */
        if (xdc.om.$name == "rov") {
            var HeapMem = xdc.module('ti.sysbios.heaps.HeapMem');
    //        if (xdc.om['ti.sysbios.heaps'].HeapMem.$used) {
                var Program = xdc.useModule('xdc.rov.Program');
                var HeapMemCfg =  Program.getModuleConfig(HeapMem.$name);
                if  (HeapMemCfg.primaryHeapBaseAddr != null) {
                    var base = Program.getSymbolValue(HeapMemCfg.primaryHeapBaseAddr.substr(1));
                    var end = Program.getSymbolValue(HeapMemCfg.primaryHeapEndAddr.substr(1));
                    /* Retrieve the MemoryImage java object. */
                    var Model = xdc.module("xdc.rov.Model");
                    var memReader = Model.getMemoryImageInst();

                    /* retrieve the sections list and add a new section */
                    var sections = memReader.getSections();
                    sections.addSection(base, end-base);
                }
    //        }

                /* Retrieve the MemoryImage java object. */
                var Model = xdc.module("xdc.rov.Model");
                var memReader = Model.getMemoryImageInst();

                /* retrieve the sections list and add a new section */
                var sections = memReader.getSections();
                sections.addSection(0x20000000, 0x20005000);
        }
    }
