Hi Xingxing,

Please see below register assignments required:

0x1F=0x00 # set 1.6Gbps speed
0x21=__ # change forwarding method if desired, otherwise can skip step
0x33=0x61 # 2 lane, non continuous clock, CSI output enabled, initial skew cal enabled
0x20=0x00 # enable forwarding of port 0 and 1

Best,

Zoe

Any register can set deskew length? I tried above setting, but can not work on my side.

Hi Xingxing,

In the UB954 there is not an option for flexible skew calibration sequence length. The skew calibration sequence length should be 2^15 bits.

Best,

Thomas
