512M DDR configuration for DM816x VS2 Demo

Hi All,

I am working on DM816X EVM. By default VS2 demo is running with 1GB DDR and I am able to compile it and run it.

I want to run my demo with 512MB DDR. So I had done some changes in omx_05_00_00_11.

My changes are as below to migrate to 512MBDDR.

1) omx_05_00_00_11/packages/ti/omx/build/config.bld

 set   var platFormMem = "512M";

2) omx_05_00_00_11/packages/makerules/build_config.mk

  set PLATFORM_MEM = 512M

And try to compile omx_05_00_00_11 package and getting compilation error at linking time.

Below is errors which are coming.

"/home/sweta/install/release/vs2/obj/ti816x-evm/m3vpss/debug/vs2_configuro/linker_mod.cmd", line 696: error:
   run placement fails for object ".bss:extMemNonCache:display", size 0xbaf2c

make[1]: Leaving directory `/home/hitesh/ezsdk_5_11/omx_05_00_00_11/packages/ti/omx/demos/vs2'
make: *** [vs2dm3] Error 2


So what can be the issue over here. Is there any configuration missing?

Please reply me. If you need more details than let me know.


Thanks,

    Hello Hitesh,

    You might want to look at a forum post I ran into while researching a problem our team's been

    having trying to light up the video subsystem's CortexM3s on an alpha board using only 512MB

    or RAM instead of a full 1 GB.

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/119202.aspx

     

    The reply to that post indicates that a 512MB RAM setup will run into problems under the current

    [ti-ezsdk_dm816x-evm_5_01_01_80] when trying to talk to the Ducatis/CortexM3(s).

     

    I haven't had a reply from TI yet to my post requesting confirmation of this.

    We're trying ourselves to work on a procmgrapp loading issue for the M3 that we think is being caused

    by using only a 512MB memory map.

    [See http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/123276.aspx  for that description].

     

    Hope this helps or gives you some ideas for investigation.

    Please update the E2E community if you find out anything specific about this.

    Good Luck.
