The datasheet of kirin970 mentions the existence of DisplayPort which can be used for second display.
How can we make use of the DisplayPort with the hikey970 board?
Can I make use of the DisplayPort by just soldering the DisplayPort connector on the respective pins of hikey970?
How can I make use of the second display as mentioned in the datasheet of kirin970?
I am not aware the DP port being made available. There is only HDMI and DSI (HS) made available through a switch.
Can we solder one DP port on the DislayPort lines?
Or do the USB-C ports support Alt mode for DisplayPort?
This boards only supports USB2.0 on TypeC, no DP lanes or USB3.1 supported.
hikey970 does not have dedicated DP lines as I mentioned previously.
DP support over USB TypeC (e.g. Alt mode) is not supported due to the AUX lines BA2/BB1 are NC - you can find this on the schematics.
