Forum Post: Some Linking Warning of HeapMem Setting

Hi,

   I managed to get an xDM verified on C674x DSP in DM8168.  I could successfully connect to the Platform via CCS and run a testing program.  Since the non-volatile memory such as NAND is not available now, I decide to load my Test Vector to the RAM manually, by using the XDS100v2 Emulator.  After processing, I could also dump the data from RAM to file in my computer.  Thus, I modified the cfg file in my project, creating 2 Heaps @0x9000_0000 and 0x9800_0000 as below:

Program.sectMap[".InHeapMap"] = new Program.SectionSpec();
Program.sectMap[".InHeapMap"].loadAddress = 0x90000000;
Program.sectMap[".InHeapMap"].runAddress = 0x90000000;
Program.sectMap[".OutHeapMap"] = new Program.SectionSpec();
Program.sectMap[".OutHeapMap"].loadAddress = 0x98000000;
Program.sectMap[".OutHeapMap"].runAddress = 0x98000000;

Memory.defaultHeapSize = 4096;
var heapMem0Params = new HeapMem.Params();
heapMem0Params.instance.name = "InHeap";
heapMem0Params.size = 120800;
heapMem0Params.buf = null;
heapMem0Params.sectionName = ".InHeapMap";
Program.global.InHeap = HeapMem.create(heapMem0Params);
var heapMem1Params = new HeapMem.Params();
heapMem1Params.instance.name = "OutHeap";
heapMem1Params.size = 30200;
heapMem1Params.sectionName = ".OutHeapMap";
heapMem1Params.buf = null;
Program.global.OutHeap = HeapMem.create(heapMem1Params);

   Actually, it does run well, as I could load, dump and get my algorithm tested in the next procedure.  However, when I tried to rebuild the project, I find there are some warning issues cast on the console:

<Linking>
"./configPkg/linker.cmd", line 157: warning #10083-D: LOAD placement ignored for ".InHeapMap": object is uninitialized
"./configPkg/linker.cmd", line 158: warning #10083-D: LOAD placement ignored for ".OutHeapMap": object is uninitialized
"./configPkg/linker.cmd", line 157: warning #10096-D: specified address lies outside memory map
'Finished building target: TestG722Enc.out'

   I have no idea with them.  Since I don't know much about the cfg file and the C6x compiler, I could only post the issue in this forum.  Could you help me with these issues?

Ps.  I have raised the same problem in BIOS forum.  Here is the link:
