Hello,
I read there is possible to use HDMI as console output on rk3399, but I
do not find any documentation about this, only Google AI give some
hints, but mostly mix up rockchip and sunxi stuff.
I have a Giada DN74 which is based on rk3399 but I am not able to enable
HDMI output in u-boot.
I check in which defconfig is use necessary configs (|example:
CONFIG_VIDEO_ROCKCHIP|) and which one is similar to my board, I choose
nanopi-m4-rk3399_defconfig and build u-boot but no output.
Is the HDMI output in some rk3399 board enabled by default?
There is documentation about HDMI output in u-boot?
If not documentation, someone could please write a sort advise how to
enable HDMI output.
Regards.
Tamás
