HDMI output for EKH-01 (1)

We have display device (Adafruit 7" 800x480), and a micro-hdmi to HMDI cable to connect it with our EKH-01. It doesn’t seem to work out of the box after connecting it, neither it shows under /dev/. Any idea how to get this working?

try using tvservice -s and see if anything pops up.

Enable HDMI after boot on Raspberry Pi4 - Installing and Using OpenWrt - OpenWrt Forum might be useful.

I’ve never tried - always in UART land here if I need access.

Sorry I forgot to power it on using the micro-usb connection. Now its working
