    Hi Meng Ke, 

    Are any issues identified on the display side at this point in time? Some imagers may include embedded data lines which will be included in the vertical line count number. 

    In addition, registers 0x75-0x76 will read back in bytes not pixels. With the current readback of 2904 bytes, we do the following conversion to pixels: 2904*8/12 = 1936. Is this expected for the imager selected?  

    In the register readbacks that were provided it looks like there are CSI errors showing on the link. Would you be able to confirm if these errors are reoccurring by completing one complete register dump for the impacted RX port and repeating the process once more. CSI errors may occur during the link initialization process however, key item here is to understand if these errors only occur during the initialization or happen during run time. 

    Best,

    Zoe
