Hi everyone, i’m struggling on a apparently random issue: my tx2 disconnects from my wifi network during streaming of images from zed camera.
It happens no matter what the streaming resolution or framerate i use.
I looked in kernel logs and i found some strange behaviours of the ZED usb device like:

plus a
"(NULL device *): nvhost_channelctl: invalid cmd 0x80685600"
error just before the wifi disconnection.
I’m using Jetpack 4.2 on a tx2. The version of the ZED sdk is 3.0.
