Hello,
When I use opencv or ffmpeg to open /dev/video1 (camera yuv422 format)
I also find the error:
[ 16.663811] usb 2-1: WARN: Max Exit Latency too large
[ 16.668905] usb 2-1: Could not enable U1 link state, xHCI error -22.
[ 16.675867] usb 2-1: WARN: Max Exit Latency too large
[ 16.680960] usb 2-1: Could not enable U2 link state, xHCI error -22.
PS: usb3.0 Camera, 640x480 100fps yuv422 format
yocto: 4.9.88_2.0.0_ga
The system is normally use and display.
Anyone can help me?
Hello Alex,
You can use the ffmpeg and opencv with i.MX8 but you have an issue with your usb, try to see if this does not appear in a PC. The usb device is wrong.
