DS90UB954-Q1: CSI_CLK0 has signal but CSI D0-D3 have no signal.

Part Number: DS90UB954-Q1

Hi Team,

Now my customer use 2*933+954, there is CLK in 954 output but no data.

The LOCK signal is normal and CSI_CLK0 has signal but CSI D0-D3 have no signal.

The following is the only thing customer configure:

write(0x4c, 0x01); //RX0

write(0x33, 0x23); //2 lane, Enable CSI output, Enable continuous clock mode

write(0x20, 0x20); //Enable RX0, Disable RX1

  • Hello Amelie,

    please in the 954 configure register 0x7D[1:0] = 1 and then check register 0x4D, which value do you see there?

    Also reading the following register would help to understand what is going on:

    0x35, 0x73, 0x74, 0x75, 0x76, 0x7A, 0x7C
