Issue with IMX93 MIPI CSI2: RAW10 custom camera hanged-up – no data captured

[caohieu]

Hello, I am currently deploying a system using the SB-UCM-iMX93-Compulab development board.
My project uses a custom camera (Onsemi-AR2020, 20MP, 5120×3840) with output format SBGGR RAW10.
The custom camera has its own clock, and does not require a reset or power-up trigger.

-  I am using Yocto-project to build a kernel module, which I forked from here:
https://github.com/compulab-yokneam/meta-bsp-imx9/blob/EVAL-UCM-iMX93-3.0/README.md

-  Previously, I used my camera on the RPi CM4. I then brought up the AR2020 on the i.MX93 after applying some fixes mentioned here:
https://www.virtanatech.com/blog/indoor-nano-drones-integrating-a-vio-capable-mipi-csi2-camera-on-th... 

-  And then, I modified Yocto-project with some patches, referencing here:
https://github.com/pleiades-br/meta-pleiades-canopus/tree/b58e3fcd92d0b502d0212208bc67da189b57243f/r... 

With my setup, I started the MIPI camera clock at a relatively low frequency to check whether it must be running. The value was-op_sys_clk_freq_mhz(MIPI_DATA_RATE): 149.4643 MHz.

However, it hung during image capture:

^C
--> So I had to cancel at this point.

Absolutely no data was captured.:

Any solution for this, or what can I do now to fix this issue?
I attached some Yocto-patches related to the project.
I would greatly appreciate any support or suggestions from you.
Sincerely, thank you everyone.

How can I convert SBGGR RAW10 to RGB/YUV on the i.MX93? Using bayer2rgb is very slow — 30 fps drops to 8 fps

[vprajapati]

Did you find any solution?

I am facing same issue and same log I am getting. Not able to capture frames from sensor.

Hello,
Downgrading the kernel image to version 6.1.55 fixed my issue.
