DS90UB960-Q1: send data all failed though CSI-2 when paired with 933.

Part Number: DS90UB960-Q1
Other Parts Discussed in Thread: DS90UB933-Q1
Hi team,
We have four camera(with DS90UB933-Q1 inside) connect with one 960. They work well most of the time, but occasionally the 960 failed to send data, especially when running the app for the first time after power on. All the register values have been read out and put in the attachment(0x50-0x53 are the I2C address of DS90UB933-Q1).
My question is: What is probably the reason for this? Any clues are greatly appreciated.
Thanks!

Hi,
could you explain what is the " but occasionally the 960 failed to send data,"?
how do you detect that 960 has no data output?
regards,
Steven

Hi,
I can see the camera image on the screen if 960 works well. I can also see the registers in the 960.
The register value in 960 that I cannot understand is: 0x92-0x93 is always equal to 0x90-0x91. Does it mean that the data 960 sent via CSI-2 is wrong?

Hi, reg. 0x9x is used for debug.
for normal operation, pls check reg. 0x4c/0x4d/0x4e firstly, any error is reported here? pls read >=2times.

Hi,
We confirm with our camera FAE, it seems like camera problem(ti933 circuit problem). Already solved, thanks!

DS90UB960-Q1: send data all failed though CSI-2 when paired with 933.
