DS90UB954-Q1EVM: tpg is not streaming

Prodigy 45 points
Part Number: DS90UB954-Q1EVM

I am using Nvidia Jetson Xavier to capture the TPG

but I am getting error err_intr_stat_ph_ecc_multi_bit_err

output package lack the ECC package

How to send ecc along with tpg packet

I have written the following register to find and getting mipi data 

i2cset -f -y c240000.i2c 0X0030 0x0033 0x01 also use 0x021 since i am using 2 lane mode

i2cset -f -y c240000.i2c 0X0030 0x00B0 0x00

    Hello Varum,

    are you trying to enable the Pattern generator on the 954 ?

    Hi 

    Yes I am trying to generate pattern in 954 after sending the data in i2c to the respective registers i mentioned above I am getting mipi data(I checked it with a oscilloscope ) but I am unable to receive it.

    I am getting an error : err_intr_stat_ph_ecc_multi_bit_err

    I think the output package from the 954 lack the ECC package

    Kindly help me fix this issue.

    Why are you writing some extra lines after 0x1F ?

    Hi

    I finally got the Pattern for the Registers you gave Thank you.

    Please let me know does it only produce Single color. If there is a way to change color can you tell how to do it?

    Hello Varum,

    the script I provided shall generate 8 different color bars. You need to double check your timing parameters to find why the colors look like this!

    hi

    Okay Thank you I will check on it.

    Can you let me know what is the line length of the Register settings you gave?

    Please also confirm that the data is in RAW10 format.

    Hi   

    Can you also tell me what is the pixel format ?

    My code needs to Receive BGGR

  • 0 in reply to Varun Pandithurai
    TI__Guru** 103215 points

    Varun,

    This actually looks as expected. The colors you are getting are based on your ISP conversion from RAW to RGB and the reason that you have non-uniform distribution of bars is based on the block size and the number of bytes per pixel for RAW10. I provided an explanation in this other thread as to why the patterns look this way: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/975823/ds90ub954-q1-how-to-set-pgen_colorx-registers-to-get-at-least-3-color-bar-in-rgb-by-raw12-format

    There is no concept of "BGGR" in this type of pattern as the serializer doesn't pack data in this way when generating patterns. The mode you are configuring is basically sending fixed bytes of the same value based on the configured block size for each bar. The 8 bars correspond to the CSI-2 reference pattern from the CSI-2 spec. 

    X bytes of 0xAA (high-frequency pattern, inverted), X bytes of 0x33 (mid-frequency pattern), X bytes of 0xF0 (low frequency
    pattern, inverted), X bytes of 0x7F (lone 0 pattern), X bytes of 0x55 (high-frequency pattern), X bytes
    of 0xCC (mid-frequency pattern, inverted), X bytes of 0x0F (low-frequency pattern), and Y bytes of 0x80 (long 1
    pattern).

    The "X" above is based on the block size so for RAW10 it would be 5 since RAW10 uses 5 bytes per 4 pixels. So set indirect register 0x02 = 0x35 instead of 0x33 above. 

    Best Regards,

    Casey
