Run OMX EZSDK Examples

Xavier
Genius 3180 points

Hello all,

I want to start my multimedia development as soon as quickly on the DM8168 evm board.

And i start  from running  omx ezsdk examples in /ti-ezsdk_dm816x-evm_5_02_02_60/component-sources/omx_05_02_00_15.

I follow " http://processors.wiki.ti.com/index.php/OMX_EZSDK_Examples#OMX_Examples_Provided_in_EZSDK" to start my work.

First i built my app in following steps.

 $ make components 
 $ make omx
Second i want to run the app,
 
•# /prcm_config_app s
-sh: /prcm_config_app: not found

 # insmod syslink.ko
insmod: can't read 'syslink.ko': No such file or directory

I think there are some steps i have missed, but i can not tell where?

As a newer to the linux add ti arm development , can you give me more details ,what 's problem is ?
Is there any help files to tell the user how to use the app and being familiar with the developing on EVM 8168?
I download uImage through tftp, and NFS is used for filesystem. How can i solve this problem?

Regards 
xavier

     $ make omx

    Dose this step will update the NFS filesystem automatically?
    Dose not omx need to  be installed by make install?
    Is there any difference that if arago-base-tisdk-image-dm816x-evm is used when developping?

    Second i want to run the app,
     
    # /prcm_config_app s
    -sh: /prcm_config_app: not found

     # insmod syslink.ko
    insmod: can't read 'syslink.ko': No such file or directory

    I think there are some steps i have missed, but i can not tell where?
    Just search all the files ,and copy them in one folder?     if so which syslink can be used, i found three different syslink.ko files ?

    As a newer to the linux add ti arm development , can you give me more details  ?

    Hi Xavier,

    Prebuilt OMX demo images can be found on your root filesystem.
    usr/share/ti/ti-omx/

    If you re-build any OMX application then you need to copy (A8 Linux) binary file to filesystem.
    You can search for syslink.ko on you file system then give path for insmod.
    lib/modules/2.6.37/kernel/drivers/dsp/

    Thanks!

    Hi Sathish,

    Thank you for your replay ! I've run the Decode_Display example successfully finally! And i am going to run the capture_encoder example.

    Because i have no r g b 1080p 60  video signal suits for input connectors labeled J5J6J7 on the EIO card, i have to change the capture configure.

    Where can i find the capture configure? I have seen  the Demo source of the Capture_Encoder(C File and H File).It seems the all the capture setting is default.

    And where can i find the information about using the video  input freely when developing ? Is it in the HVPSS driver guide ?

    Can you tell me ?

     

    Thank you in advance!
