I have ordered a radxa-e54c for its 4 networking interfaces and IA functionality.
I am harvesting info on how to install and use it.
I have found https://github.com/radxa-build/radxa-e54c.
My conclusion, is that at the moment, there are no released os available for the device ;-(
Are those pre-release / test builds, which as mentioned are not supported, are safe to use ?
(It is mentioned: Only use when specifically instructed by Radxa support.)
Is there a general installation document describing how to install (no sdcard, no emmc) ?
