Empty Content in SECTIONS of link.xdt

Hi,

My problem was unable to get a valid link.xdt for universal_codec copy after using genpackage wizard.

I was following instructions at http://processors.wiki.ti.com/index.php/C64x%2B_iUniversal_Codec_Creation_-_from_memcpy_to_Canny_Edge_Detector#Building_the_Linux_Application .

 

I wanna integrate my codecs to a new server.

 

Unfortunately, I got an error which pointed to link.xdt. I checked link.xdt. Nothing between braces.

SECTIONS

{
}

That was the problem.

 

Then, I checked the example at dvsdk_1_11_00_universal_codecs_ccsv3_3/codecs_1_10_new/packages/ti/fae/codecs/universal_copy/link.xdt,

SECTIONS

{

% if (this.UNIVERSAL_COPY.codeSection) {

    .text:algAlloc  > `this.UNIVERSAL_COPY.codeSection`

    .text:algFree  > `this.UNIVERSAL_COPY.codeSection`

    .text:algInit  > `this.UNIVERSAL_COPY.codeSection`

    .text:algProcess  > `this.UNIVERSAL_COPY.codeSection`

    .text:algControl  > `this.UNIVERSAL_COPY.codeSection`

%}

}

There is something in SECTIONS.

 

Actually, I was using genpackage wizard to create a codec package. But in Step 6 (Generate Linker Template), nothing appear in the box. I tried different .a64P for codec of universal_copy, such as one in codec_engine_2_23/examples/xdais/dm and dvsdk_1_11_00_universal_codecs_ccsv3_3/codecs_1_10_new/packages/ti/fae/codecs/universal_copy.

 

Same results.

 

Any solution? I am using DVSDK_2_00_00_22 with xdctools_3_10_05_61.

 

Thanks.

    Vincent,

    Did you get this problem solved as your other post was for a later linker error?

    Hi Iain,

     

    The problem was not solved. This is a different case, as it occurred when calling genpackage. In the other post, I just copyed sample codec package, then created a server based on the codec. I didn't build the codec myself.

     

    In this case, I tried to build the codec package from the very start(universal_copy.a64p). In the link.xdt, nothing existed between SECTIONS{}. This finally led to an error in building server.

    //===================================================================

    package/cfg/universal_copy_ires_unitserver_evmdm6467_x64P.xdl, line 78:   error:
    //===================================================================

    However, I checked the link.xdt in the sample codec, where there was something between SECTIONS{}.

     

     

    How to handle this?

     

    thanks.

    Vincent,

    I think the problem is a typo in the instructions. When you create the codec with xs ti.sdo.codecutils.genpackage

    at step 4 can you leave the Check to update section info box ticked. This being unticked was only way I could reproduce your problem.

    So I've changed the wiki article to now read

    Step 4

    Browse for the appropriate executables:

    cg_xml: C:/dvsdk_1_11_00_00/cg_xml_2_10

    ofd6x: C:/CCStudio_v3.3/C6000/cgtools/bin/ofd6x.exe

    nm6x: C:/CCStudio_v3.3/C6000/cgtools/bin/nm6x.exe

    Tick the "Check to guess GetStackSize()" tick box.

    Stack Size Pad %: 20

    Leave ticked the "Check to update section info:" tick box.

    Select "Next"

    Hi Iain,

     

    Unfortuantely, I still got the same problem.

     

    Actually, I am developing on Linux with dvsdk_2_00_00_22. I mean, I was building the codec and unit server on Linux.

     

    Does it matter?

    Ah, I got it.

     

    I was stupid to use ceutils 1.06. That's the problem.

     

    Now, no problem with ceutils1.07.

     

    Thank you for your help,Iain.
