C6748 DSP UPP DSP/BIOS test example memory issues.

Other Parts Discussed in Thread: OMAPL138

Hi,

I have working on UPP DSP/BIOS driver to get Data from ADC. I am using upp_dvr_test.pjt  which is in loopback mode.

I have modified it to work in Receive mode. everything works fine for very less number of sample captures, but as i increase the number of samples, processor halts, and I can,t run it even through the debug is working.

 

I feel it has memory issues because all of data and program is used in IRAM as per cmd file. I am trying to chnage heap size and work with DDR memory also but I can,t modifiy the cmd comand and if i modify the tcf file it will not allow me.

I ma using DSP core of omapL138

Let me knwo you need furthure information?.

 

Also my Board is custom, i tried to run PSP drivers but it would not work also.

    Hi Fahed,

     

    Firstly, I would like to ask you a very basic question. Which version of PSP are you using?.

     

    Secondly, How have you configured your Upp application(Configuration parameters)?

    For example, number of samples, buffers, etc. It would be better if you share your application code snippet which can help us in analyzing your configuration and initialization sequence.

     

    And coming to modifying the (.tcf) file, I do not think that the CCS would allow you to change it. You need to use any text editor to modify the required parameters. I believe increasing the Heap size and appropriate memory parameters would solve your problem.

     

    Let me know the result.

     

    Thanks & regards,

    Raghavendra

    Hi,

     

    Thank you for your reply. Actually i have solved the problem.Issue was with project legacy migration from 3.3 CSS to CSSv4.

     

    When i made new project in CSSv4 and included all files and libraries. .*tcf file is now being updated and working fine.

    Regards,
