6.What problems are you experiencing?
Hi, I’m using two OV2311 mipi cameras with Jetson NX connected on develop kit(with R32.4.3) mipi port. I want to get two camera frame by hardware trigger at same time. I used C++ and python with OpenCV 4 and threading to get frame.

I can set every config I want and is working fine with program start in free run.

But when I set trigger mode to the Hardware trigger, I saw something error.

First, after I change mode to HW trigger, it will get last frame after timeout.(I think is OpenCV buffer issue, because your website mentions that.), so I used OPenCV cap.read() func serval times to clear buffer before I start trigger. It’s workaround but is there any solution to solve that because the buffer count is not same every time.

Second, after serval times hardware-trigge about 10 Hz and trigger 20 times on one loop. Got frame fine at start but failed after about 50 times loop. The error message shows
