some questions about the image_processing demo

Hi,

I tried to modify the demo in mcsdk_2_01_02_06\demos\image_processing\ipc\evmc6657l, so I created a new project in my own workspace and the copied all files form the demo to the new project. However, the new project couldn't compile and show: 

I checked the differences between the two projects, and found the demo's platform is demos.image_processing.ipc.evmc6657l.platform while my project's platform is ti.platforms.evm6657. I tried to change my platform but failed. How can I use demos.image_processing.ipc.evmc6657l.platform ?

    Besides, the resourcemgr.c file in the demo contain these codes:

    /* PASS RL file */
    #include <ti/csl/cslr_pa_ss.h>

    /* Firmware images */
    #include <ti/drv/pa/fw/classify1_bin.c>
    #include <ti/drv/pa/fw/classify2_bin.c>
    #include <ti/drv/pa/fw/pam_bin.c>

    I noticed these header files are only valid for C6670 and C6678, why can the demo compiled?

    Yuxin Yuan,

    When you create new project should be choose the relevant device or board family correctly. And also check the dependent packages. Please compare the original project settings with your newly created one. I can suggest you, instead of creating new one, just take the copy from an original project and add the source files to local folder for modification if needed.

    Here, Master project does not use the resourcemgr.c file, you can see that file is excluded from the project.

    Here, you can see the location of the platform

     

    Refer the excluded file, right click on the source file and find the options.

    Pubesh,

    Thank you for your suggestions and I have followed them.

    I also wonder what are the functions of Cache_inv and Cache_wb, what the parameters mean, and when should I use them?

    Yuxin Yuan,

    Please find the details for Cache_inv and Cache_wb APIs.

    Void Cache_inv(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait);

    • Invalidate the range of memory within the specified starting address and byte count.
    • The range of addresses operated on gets quantized to whole cache lines in each cache.
    • All lines in range are invalidated for all the 'type' caches.

    Void Cache_wb(Ptr blockPtr, SizeT byteCnt, Bits16 type, Bool wait); 

    • Writes back the range of memory within the specified starting address and byte count.
    • The range of addresses operated on gets quantized to whole cache lines in each cache.
    • All lines within the range are left valid in the 'type' caches and the data within the range will be written back to the source memory.

    blockPtr  -  start address of range to be invalidated. 
    byteCnt    -  number of bytes to be invalidated. 
    type          -  bit mask of Cache type. 
    wait          -  wait until the operation is completed.

    Please have a look at the section "Cache Interface Functions" in the TI SYS/BIOS Real-time Operating System

    User's Guide.

    I used the following codes to test NDK transport time:

    ts1 = (Int32) Timestamp_get32();

    /*
    * Read in the data. We should probably read this in little chunks in case ContentLength was a lie or
    * there is an error...
    */
    len = 0;
    while (len < ContentLength ){
    /* This is a work around for IE 7.0 and 8.0 */
    len = recv( htmlSock, gRxBuffer, ContentLength, MSG_WAITALL );
    }
    // printf("get image!\n");
    ts2 = (Int32) Timestamp_get32();
    ts2 = ts2 - ts1;
    processing_time = ((double)ts2 / (double)freq.lo) * 1000;
    printf("NDK time = %f\n",processing_time);

    Why I got different result each time since the code and data never changed? And sometimes the result was below zero?

    Yuxin Yuan,

    Please check the sequence as per below,

    Types_FreqHz freq;
    Int32 ts1, ts2;

    double * processing_time;

    Timestamp_getFreq(&freq);

    ts1 = (Int32) Timestamp_get32();

    ----------------------

    ----------------------

    ts2 = (Int32) Timestamp_get32();
    ts2 = ts2 - ts1;
    *processing_time = ((double)ts2 / (double)freq.lo) * 1000;

    Note: If you have new query, create the new thread.

    I wanted to do malloc in slave core, but the console show that:

    ti.sysbios.heaps.HeapMem: line 307: out of memory: handle=0x81edc0, size=2568

    I thought maybe the size of heap is too small, refer to the .cfg file in master core, I changed the heap configuration in slave core:

    var heapMemParams = new HeapMem.Params;
    heapMemParams.size = 0x800000;
    heapMemParams.sectionName = "systemHeapSlave";
    var heap0 = HeapMem.create(heapMemParams);
    Memory.defaultHeapInstance = heap0;

    ........

    Program.sectMap["systemHeapSlave"] = "DDR3";

    When I rerun the project, the Core0 aborted and the console printed:

    The Core0 aborted around MessageQ_creat(), how to correct it?

    Yuxin Yuan,

    What is the status of your  issues posted previous. We gave the solution, is it ok?. Your are keeping on jumping to next issue and not relevant with the old one. Please make sure when you are getting new issue, please post new thread instead of previous issue discussion. The multicore navigator initialization calls are supported on Core0 only.  Your issue is related with memory, what are the changes made by you.  Do the power cycle for the EVM and run the suitable project on core0 and other project on core1, core2.

    Pubesh ，

    I have taken your solution and copied the demo to make some changes. Thanks very much.

    Since my new issue is about the image processing demo, so I posted it here. I'm so sorry to trouble you. I will create a new thread to illustrate it.

    Regards.
