ERROR :
the image is
A20-OLinuXino-buster-base-20210127-100834.img
Probably it boots but the video output is not set for HDMI per default. This can be edited via:
olinuxino-overlay
navigate down and disable
micro-lcd-olinuxino.dtbo LCD-OLinuXino PnP panel
Save and reboot. Now HDMI should work.
SSH should work. Double check the addresses. If this problem remains best idea is to use USB-serial cable over the debug lines.
