Other Parts Discussed in Thread: ALP

Hi Team,

We want to verify the pattern from DS90UB954 to our SOC, we have connected CSI-2 x2 lane to DS90UB954 from SOC, below is the setting we are doing for pattern generation and using gstreamer to stream video to HDMI, please confirm the below settings are fine or we need to modify the registers,

    Hi Pradeep, 

    Based on what I saw: 1280x720 active resolution, YUV422 8-bit. 

    What is the FPS that you are looking to achieve? 

    Thanks, 

    Sally

    Hi Sally,

    We need 30FPS to check pattern.

    Please verify below register configuration for UB954 Deserializer, alias address for serializer is 0x74 and camera alias address is 0x10 in 7bit format

    i2cset -y 2 0x38 0x4C 0x01
    i2cset -y 2 0x38 0x6D 0x7c
    i2cset -y 2 0x38 0x58 0x5E

    Hi Sally,

    Anyhow now no need of serializer or camera alias address to be set in the register for pattern generation in the deserializer

    Hi Pradeep, 

    Here are the registers to set for 1280x720 (active), 30 fps, yuv422 8bit, vbp = 33, vfp = 10, vsync = 2, 8 bars with block size 4. (I noticed in your old code you had the total lines set at 800, but that didn't seem to match with the rest of the things you programmed. Let me know if I didn't get the settings right.

    0x01 0x00 PGEN_CTL
    0x02 0x34 PGEN_CFG
    0x03 0x1E PGEN_CSI_DI
    0x04 0x0A PGEN_LINE_SIZE1
    0x05 0x00 PGEN_LINE_SIZE0

    We are getting GRAY color stream but its not proper stream

    Hi Pradeep, 

    Is it just the wrong color or is something else wrong? Could you be a little more specific.

    Thanks, 
    Sally

    Hi Pradeep, 

    Can you tell me what the issue is or explain what is wrong with the output  so I can check these over? Without really knowing the issue, it's not easy to discern if something is set wrong for your setup.

    Hi Sally,

    We have configured Deseriliazer for pattern generation and capturing the frames and displaying the frames over HDMI in our processor, the issue here is we are not able to get the colour pattern with current settings of Deserializer,  We are using GStreamer for streaming the video to hdmi

    gst-launch-1.0 v4l2src  device=/dev/video12 ! 'video/x-raw,format=(string)YUY2,width=1280,height=720' ! autovideosink

    How we can identify the frames are generating in Deserializer, any debug registers are available to check or dump, 

    Issue:

    When we capture the video from deserializer we are getting GRAY video over HDMI, when we dump frames we are not getting any frames in dump

    If you are running patgen on the 954, check the port pass status in register 0x35. Are you getting port pass or no?

    Hi Sally,

    We are reading 0x35 register in 954 we are getting 0x00 always, i think we are not getting the port pass

    Hi Pradeep, 

    Do you have local I2C access? Can you connec tthe board to our ALP and run a pattern from the pattern generator tab?

    Hi Sally,

    We don't have local I2C connection exposed in board, is APL available in Linux, Can you show us how you connect your board to APL and execute pat gen

    HI Pradeep, 

    It is not in linux. You can download it on our TI website, but it requires local I2C access. Can you try just these 4 lines and tell me if you get an data output and check 0x36 please.
