[U-Boot] SUNXI : setenv video-mode not working

Fri Mar 1 11:59:37 UTC 2019

Version: u-boot-2018.09

With reference to 
https://github.com/u-boot/u-boot/blob/master/doc/README.video I've set 
the following :

video-mode=sunxi:800x480-24 at 60,monitor=hdmi,edid=0

I am would have expect that u-boot is always using 800x480 regardless 
the (higher) resolution of the attached HDMI monitor.

However, this is not working on the Orange Pi One. It is always using 
the highest resolution from the attached HDMI monitor.

Any thought's?

Many thanks in advance, Arjan
