I flashed the “VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_EMMC_V20191231.img”
I tried to power VIM3 with a socket power supply of 5v 1.35A, but nothing happened just the white led went on, then I tried with a power supply of 5V 10A still nothing happened just the white led went on.
I was expecting VIM3 to boot Ubuntu, but on the video I see nothing at all.
I did another trial and flashed an older image
I am using a monitor with multiple input HDMI / DVI-D , it is my main video, DVI-D is conneted to my home computer, and HDMI conneted , depending of the needs, to raspberry pi / Khadas.
HDMI is working correctly if I connect raspberry I see what raspberry is sending, if I connect Khadas the screen is completely black (no sign of activity at all).
