PROCESSOR-SDK-TDAX: TDA2X

Part Number: PROCESSOR-SDK-TDAX
Other Parts Discussed in Thread: TDA2

Question 1:

Hello: when I was debugging the TDA2 driver, the file directory is as follows

"PROCESSOR_SDK_VISION_03_05_00_00 / vision_sdk/apps/SRC/hlos/adas/SRC/usecases/disp_dist_src_display"

The file

VDRM_CRTC = 26 chains_dispDistSrc_Display. C,

That is:

PUcObj - > DispDistSrc_westonPrm. VDrmControllerObjectId = VDRM_CRTC;

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * excuse me: VDRM_CRTC 26 here is how to determine?If HDMI LCD1, LCD2, and LCD3 are used, what should the vDrmControllerObjectId be assigned?

Question 1:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * excuse me: if the HDMI LCD1 LCD2 LCD3 used, that here I am in terminal execution "weston - flower", how to specify the HDMI, LCD1 one shown on the screen?

  • Hello, I just refer to the above link to do it. Now I output 4 channels, HDMI, lcd1/2, and adopt 4 independent VDRM.

    How do I specify weston-flower to be displayed in these 4 channels?Like HDMI, or LCD3? 

    The document above did not seem to say!!!!!

    The document above did not seem to say!!!!!

    Here is my video card device:

    root@dra7xx-evm:/dev# ls -al vdr*
    crw------- 1 root root 246, 0 Sep 25 10:00 vdrm-controller-0
    crw------- 1 root root 246, 1 Sep 25 10:00 vdrm-controller-1
    crw------- 1 root root 246, 2 Sep 25 10:00 vdrm-controller-2
    crw------- 1 root root 246, 3 Sep 25 10:00 vdrm-controller-3
    root@dra7xx-evm:/dev#

    The following is the command I executed, which is displayed on HDMI. Now I want to display it on LCD2. What should I do?

    root@dra7xx-evm:/dev#
    root@dra7xx-evm:/dev#
    root@dra7xx-evm:/dev# weston-flower

  • Hi,

    I have forwarded your question to DRM experts for further help.

    (note that some delay in response due to the holidays in India might be expected)

  • Do you see weston background on the LCDs?

    Can you provide me the the output of "ls -l /dev", "ls -l /dev/dri" and "ls -l /dev/dri/by-path"?
