Hello Community!
I am developing an ISP board that connects to iMX8QM MEK.
The hardware configuration diagram is below.
The software uses Linux 6.1.22, and the sensor driver is created based on gmsl-max9286.c.
Below is the kernel driver log when one image is acquired from camera #0 using v4l2-ctl.
There is no interrupt in isi.0 (MIPI reception is not possible).
I have confirmed with an oscilloscope that the iMX8QM's MIPI pin contains a waveform with ISP output specifications.
Can someone please help me resolve this issue?
In the past, I created an ISP (TP2855) driver for an iMX8QM custom board and successfully streamed 4 cameras.
Using the same method, I changed the ISP to GEO GW5 and ran it with two cameras, resulting in the current state.
This is the same as the issue linked below, and is it due to the iMX8QM errata?

The kernel log when running v4l2-ctl is shown below.
