iMX8 QuadMax ADB connection unreliable

[mt_android]

Hi,

I have android running iMX8 QuaMax board that connects to my laptop, however ADB connection is unreliable. When plugin usb, the device is shown by running adb devices, and I can use adb shell/push for a while, and then the device is offline. I need to reconnect usb cable to get the device back.

Is it a common issue? And how to fix it?

Thanks a lot.

Possibly UART connection is weak and the connection drops by some glitch.
Please try to change cable, etc.

I changed the cable, and it is the samething. The ADB connection gets lost in several minutes after plugged in.
