Other Parts Discussed in Thread: TPD12S015
I have a AM5728 custom board.
I use ti-processor-sdk-linux-am57xx-evm-06.03.00.106-Linux-x86-Install.bin
There is no output from the vout1 interface on my custom board
This is my device tree

Originally HDMI can be displayed, but after adding lcd0, hdmi and lvds can not be displayed
Is there a problem with my device tree? How can i modify?
this is my schematic
