DS90UB954-Q1: The change of Mipi channel leads to incomplete image

Part Number: DS90UB954-Q1

Sorry, it took a long time. We redesigned the MIPI CSI-2 hardware connection between the Imx8 and the 90ub954, but the problem was not solved.

Reg 0x4E = 0x4D

Reg 0x7A = 0x0E

“These errors could indicate an issue with the connection“

How to confirm that there is a problem with the connection of that part？

Hello,

Thank for your email. Let me ask some clarification email. Let'd debug a few things to understand the situation.

Once we have PATGEN working we can do the following debug.

Turn in 954 patgen --> SoC to detect any errors. If no errors, we will go to step 2
Turn on 953 patgen --> 954--> SoC

Please provide the system required video settings, to double check PATGEN is setup correctly.
