MIPI camera performs stably on Orin Nano Devkit (P3767-0005), but is unstable on the Commercial module (P3767-0003).
Test Conditions:
- Both use the P3768 carrier board.
- Use the same Nvme SSD, which contains the JP5.1.3 version system.
Test Method:
- The camera resolution is 5M@20fps, using
v4l2-ctlto capture images.
- Camera0
v4l2-ctl -d /dev/video0 --set-fmt-video=width=2592,height=1944,pixelformat=UYVY --stream-mmap --stream-count=-1 --stream-to=/dev/null
- Camera1
v4l2-ctl -d /dev/video1 --set-fmt-video=width=2592,height=1944,pixelformat=UYVY --stream-mmap --stream-count=-1 --stream-to=/dev/null
Problem Description:
- Using P3767-0005 and P3767-0003, if only one camera’s image is read at a time, it is stable.
- When reading images from both cameras simultaneously, it is stable using the P3767-0005 board; however, using the P3767-0003 board, errors occur quickly, as shown below:

My Attempts:
- I followed the camera bringup steps to trace the error logs. However, due to the excessive information from
cat /sys/kernel/debug/tracing/trace, the frame rate significantly drops, making it difficult to effectively debug. - I tried increasing
serdes_pix_clk_hz, but it was ineffective. - I attempted to boost the clock for debugging, but it was ineffective.
- I looked for hardware differences between P3767-0005 and P3767-0003. So far, I believe the only difference is that P3767-0005 has an SD card slot, but everything else is the same.
Request:
Do you have any debugging suggestions for me?
