We have flashed the Evo Xavier with the latest firmware supplied by Miivii Tech and realize that no HDMI display works anymore.

After booting the "dmesg" system log keeps displaying "powerdown".

Any idea what could be the reason? We have tried several monitors and several cables and the monitor doesn't show anything ...

By check the youtube vedio, it looks like the eMMC full to make HDMI display flash.
There are three ways to do the debug:
1. SSH by using network to the EVO Xavier, check if Xavier has enough space.
2. Re-flash EVO Xavier to your old image version, to make sure the hardware has no problem.
3. Re-download the image and bootloader from our data center, to make shure the image has no problem.
