Hello everyone, We built a custom carrier board that connected four ov_5640 cameras via GMSL. We found that the system crashed under L4T R35.5 when executing test_camera.sh for the second time. test_camera.sh is a script that uses gstreamer to open the four cameras by using gstreamer. The system…

Have a check this attached. camera-rtcpu-t234-rce.img.r35.5.dbg.idac (519.4 KB)

Could you check if still have below error message after apply the RCE firmware. General error queue is out of sync with frame queue. Thanks

Hi ShaneCCC, We didn’t see that error messages after applying the patch and firmware. But the system still crashed. Please see the attached kernel log. putty.log (120.6 KB)

Looks like unable to capture from the GMSL and try to recover many times and crash finally.

Hi ShaneCCC , Here are some test result for your reference. FW version R35.4.1 vi5_fops.c R35.5 vi5_fops.c R35.4.1 Camera FW OK NG R35.5 Camera FW NG NG Async Camera FW NG NG

Hi ShaneCC, Here are the logs. r35-4-fw_r35-4.log (129.6 KB) r35-4-fw_r35-5.log (131.1 KB) r35-5-fw_r35-4.log (278.9 KB) r35-5-fw_r35-5.log (247.4 KB) Async-fw_r35-4.log (186.5 KB) Async-fw_r35-5.log (770.3 KB) I found that system didn’t crash if I use the vi5_fops.c from R35.4.1. But the ca…

No matter kernel crash or not both have capture failed. Do you try single camera instead of multiple cameras. Thanks

Hi ShaneCCC , The kernel would not crash if we only open one camera.

Does the log show the capture failed and timeout if open single camera only? Thanks

Please confirm on r35.4.1 for single camera if have failed and timeout message. If yes, I would suspect the camera timing or signal problem.
