Hi Casey,

Thank you for your reply. Is there any update about this question? Or if we have the registers configuration information for reference of demo board.

Many customers have the same question about the register configuration and hope to provide the examples for reference.

Best regards

Hi Kailyn,

Which sensor are you using? Please let me know if you are using the sensor that came with the 953 demo board.

Hello Casey;

Thank you for your reply, he used IMX385. Now his question is that the port1 could link normally, but port0 couldn't. I suggest him to do the BIST test and didn't give me feedback. Then I would confirm with the customer.

Hi Kailyn,

It is strange that port1 is working but not port0. Is it possible to share the customer schematic? I'd like to see if there are any differences in the schematic between the two ports.

Also, can you confirm the customer is able to speak with the sensor using port1 with no issues?
