For my H96 Max 4GB 64GB box, the Debian Buster minimal - legacy kernel (Built date 2021-04-16) boots up fine after burning it to the emmc using the multitool image. Wired connection works fine, but the wifi does not work (the interface shows up, but nmtui is unable to connect to access point).
But other images (Debian Buster minimal - mainline kernel, and Ubuntu Focal desktop [xfce], built date 2021-05-30) does not boot (I think). Specifically, after burning to emmc with multitool image, when I plug the box in, HDMI output remains dark.
I saw on the forum that some people managed to get the exact same box to boot.
I'll appreciate any help with trouble shooting to figure out what I am doing wrong.
