DRA722: IPU1 firmware load fail on Vision SDK

Part Number: DRA722

I build Vision SDK 3.08 on my custorm DRA722 board, when build ipu2 into vision sdk like:

PROC_IPU1_0_INCLUDE=no
PROC_IPU1_1_INCLUDE=no
PROC_IPU2_INCLUDE=yes
PROC_A15_0_INCLUDE=yes
PROC_DSP1_INCLUDE=yes

sample_app.out run ok , but it load firmware fail when enable IPU1 ( enable or disable IPU2 ) , linux startup log:

[   16.988346] remoteproc remoteproc0: powering up 58820000.ipu

and run sample_app.out it will print "SYSTEM: Attaching to [IPU1-0] ..." , I need help ,thank you!

  • Hi,

    in Vision SDK, if A15 is running Linux, you can only enable either IPU2 or IPU1_0 but not both. 

    Regards,

    Stanley

  • Thank you very much, Why IPU2 and IPU1_0 can not be enable both ?  but load firmware fail when IPU1_0 enabled only , I want to enable IPU1_0 for my custom image processing and using gsteamer ( IPUMM  ) as h.264 codec .

  • It is attaching IPU1_0 fail when I enable IPU1_0 only , sample_app.out print out :

  • You can't enable both IPU2 and IPU1_0 or IPU1_1 if IPU2 is set as the primary core. This is a limitation of the VSDK framework.

    Please refer to section 4.4 IPUMM based decode use-case using Gstreamer in ~/vision_sdk/docs/Linux/VisionSDK_Linux_UserGuide.pdf.

    You can enable IPUMM on IPU2 but make sure to have IPU1_0 set to primary core.

    Please do a clean build afterward so the change will take effect. Otherwise, you will have problem with IPC attach as shown in your log.

  • Thanks , but I tested cases:

    1. Enable IPU2 only and set IPU2 as primary core ;

    2. Enable IPU2 and IPU1_0 and set IPU2 as primary core (I know is should be fail) ;

    3. Enable IPU2 and IPU1_0 and set IPU1_0 as primary core;

    4. Enable IPU1_0 only and set IPU1_0 as primary core.

    Only  case 1 , The sample_app.out looks like ok , others , kenel logs "remoteproc remoteproc0: Failed to load program segments: -22" and sample_app.out print "SYSTEM: Attaching to [IPU1-0] ... " 

    When I enable IPUMM based on 4 cases above, gstreamer fail , it print out : 

    root@dra7xx-evm:~# ./decode_ipumm.sh

    Spinning.  Please run 'gdb gst-launch-1.0 795' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
    

  • Please review the build and run instructions in the User Guide again.

    You should use "apps.out", not "simple_app.out".

    simple_app.out doesn't have any demo. It is a barebone example for you to add your own apps.

    Regards,
    Stanley

  • Er , review and try many times !!!

  • Did you try "app.out" instead of "simple_app.out"?

    If yes, please share the log again from app.out.

  • Because my board is customized,  app.out is hardware depend , It need porting to my custom board .
