Linux/DS90UB933-Q1: 964 + 933+AR0143 Can't receive any sensor data.

Tool/software: Linux

Hello,

We use ub964 + 933+ar0143 automotive solution. SOC can't receive any sensor data There is no mipi signal on ub964 mipi bus, but sensor ar0143 outputs pclk and data at the same time. And also, ub964+913+ov0143 solution is OK. We can get sensor data.

1 We don't know if there is something wrong with 933+ar0143 hardware module. Can we know camera modue hardware problem by the 933 or 964's register?

2 if we need to configure 933's register?

B.R.

Sorry, Here is wrong. "And also, ub964+913+ov10640 automotive solution is OK. We can get sensor data."

ar0143 I2C communication is OK, but we can't get sensor data.

Hello,
Do you see this problem if you swap out the camera module for a different one? This can help isolate if the problem is with a specific camera module. You can also look the CRC error registers on the 964. Refer to the datasheet for additional details.

ub933 and UB913a are p2p compatible, also reg. setting is compatible.

if the link ub964 + module with ub913a can work, the link ub964 + same module with UB13a but with UB933 as replacement also should be ok.

so for your issue, I think the module with UB33 is NOT same as the module with UB913a, correct?

if yes, please check the module UB933 hardware design firstly. TI has refer. EVM design guide, please follow up it, thanks.

regards,

Steven
