Cannot connect using adb

Chip Platform Rockchip
1

We have two RK3399 boards. Once is a 2GB version running Android 6, which I can connect using adb no problem. However, we just received another board which is 4GB and is running Android 7. I am not able to connect to it using adb. The driver loads and reports no errors, but “adb devices” shows nothing.

Thanks for the response. Is this change something that was made to the released images? I have been using other boards that don’t have this issue. I have not yet tried re-flashing this board with the latest image.
