Hello,

I am already followed your instruction, and using yavta, can see streaming from /dev/video0.

However, your example of SDK is hanging at the line of “arducam_set_mode(…)”.

Here are infos about my system.

uname -a

Linux raspberry pi 5.10.10+ #1397 Mon Jan 25 18:35:09 GMT 2021 arm6l GNU/Linux.

My guess is that ov9281 HW, settup, and streaming from /dev/video0 is OK,

but only thing of trouble is your SDK with hanging during set the mode of ov9281.

Thank you.

Hoyoung Lee.

arducam_set_mode seems to be incompatible with the kernel driver, from the link you posted, I assume you are using that one. Try to remove the dtoverlay=ov9281 entry and use the userspace driver which is sadly being closed source: https://github.com/ArduCAM/MIPI_Camera/tree/master/RPI
