Issues¶

Where is my video?

Have you written (via dd or otherwise) the *.img file to a micro-SD card (as opposed to a USB)?

It is a known problem that no video appears when outputting video through the HDMI connector. Try toggling your monitor/TV inputs and see if the video signal appears.

Is the blue LED blinking? If not, please diagnose the issue via UART interface (see the How-To page) for more detailed information.

If the operating system image was not flashed correctly, there will be no video output since these devices do not have a BIOS or POST step during boot.
