DS90UB954-Q1: MIPI in RAW10 mode

Hi TI Team,

 I have DS90UB954 in our platform.

I have a camera connected to 954 which has PCLK of 94MHz, 30FPS,1280x800, 16bpp

If  DS90UB954 is configured  for 2 lanes with 800Mbps capture of  frames from camera is working.

If  DS90UB954 is configured  for 4 lanes with 800Mbps capture of  frames from camera does not work

SoC is capable of receiving 2.5Gbps/lane.

Do you say that if camera of PCLK 84Mhz and if 954 configured for 800Mbps with 4 lanes, does capture work???

    Hi,
    if 2lanes CSI2 port with 800Mbps/lane can work, the 4lanes setting should also work. can you check what is the issue:
    1. pls measure the CSI2_CLK output after UB954?
    2. pls check the error detection in the SoC when UB954 is set as 4lanes output.
    3. pls check UB954's reg. setting when change to 4lanes, and the SoC's CSI2 port setting as well.

    regards,
    Steven
