Hi fellow T3+ owners. I have the same situation; Armbian Bionic for T3+ panics right after boot, probably the memory config has changed.
However... if you use the T3 (non plus) armbian image I can not only boot but can flash it to eMMC (I am not saying this is a perm solution).
WiFi works, haven't tried camera but looks stable enough for development.
The only issue I have is the usable memory is 1Gb instead of 2Gb. Where does armbian get the available memory from, is it auto detect or is there something like a boot.txt ?
