Hi,

As titled, customer use 933 with 960.

they want to achieve raw10 input mode with YUV422 CSI-2 output, is that OK? seems that 0X70 and 0X71 is right register, how to use that to achieve data format change?

thank you!

    Hi Yuan,

    If you are using RAW10, you will need to select the RX port (Reg 0x4C) and then configure register 0x70 RAW10_ID. You must configure the YUV422 data code in bits [5:0]:

    YUV422 8-bit = 0x1E

    YUV422 10-bit =0x1F

    You can find all of the data codes in the MIPI CSI-2 specification document.

    If you are using 8-bit mode, you will need to also configure 0x7C[7:6] to select whether the upper 8-bits or lower 8-bits is processed (see this E2E for details). You can also optionally change 0x70 bits [7:6] if you want to remap the virtual channel ID assigned to the port receiving RAW10 data. 

    Regards,
