Hi, I can't get my RB5 board to work. I'm working on an Ubuntu 18.04 system. I have created a code image that seems to have been created correctly, downloaded and flashed but the board doesn't seem to be able to communicate with the laptop using adb. Adb doesn't find any devices. I have also tried connecting to the micro USB serial debug port but no data came through. Green LED1 turns on only after the power and the USB C are plugged in. The LED continues to stay on permanently afterwards. An HDMI display was also attached and the 8 cores could be seen but signal was quickly lost afterwards.
Any advice would be really appreciated. Thanks.
