Hi,all,
We are using our own carrier board connected to an AGX Orin 64G module running JP6.2;
We have connected an 8MP + 2MP camera via a MAX9296. When configuring MIPI 2-lane, the 8MP camera works normally, but when both the 8MP and 2MP cameras are enabled simultaneously, the data rate is insufficient, resulting in frame drops;
We considered switching to MIPI 4-lane to accommodate the data transfer requirements of the 800W + 200W cameras. However, after configuring 4-lane MIPI, we found that when the 800W camera was enabled alone, the kernel produced consistent error messages. Furthermore, when testing with different baseboards, the camera sometimes failed to start at all;
The system logs are as follows:

We have already implemented the following modifications in the code:
Code modifications for 4-lane MIPI:
Additional information is provided below:
The MAX9296 has a 0x320 register; we configured it to 0x35 by default, but frame drops occurred during 4-lane MIPI reception on the Orin side;
When configured to 0x3a, frame drops no longer occurred during 4-lane MIPI reception on the Orin side.
What troubleshooting steps or modifications can be performed on the Orin side to ensure no frame drops occur?
