OS08A10 low FPS

VIM4
1

I have khadas vim4 with Fenix 1.7.5 Ubuntu 24.04.3 LTS Linux 5.15.137

I connected camera (OS08A10). But I can’t get 60 FPS.

I think you used the old VIM4 without NPU, right? Only the New VIM4 supports the 4K@60fps framerate.

3

I use khadas vim4 v12 2203. Is it not supported 4K@60fps?

4

Yes, only supports 4k@30fps.

Thanks for your answer!

It’s strange why I can’t get fps 60 at a lower frame resolution (1920x1080).
