Hi, everyone. We are developing a customized carrier board with TX2.The HDMI circuit of the customized mother-board was as same as that of the devkit.
We meet the HDMI & USB problem as somebody posted here before again.(https://devtalk.nvidia.com/default/topic/1027467/jetson-tx2/hdmi-problem-of-the-tx2/1)
The error message is
tegradc 15210000.nvdisplay: sanitize_flip_args: WIN 3 invalid size:w=0,h=0,out_w=0,out_h=0
We already tried to mod xorg.conf to use debugmode. and figured that the EDID was loaded correctly.
the log showed
[ 25.361] (II) NVIDIA(0): Setting mode "HDMI-0: nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0}"
[ 26.670] (EE) NVIDIA(0): Failed to set the display configuration.
We also read this article(https://devtalk.nvidia.com/default/topic/1027442/jetson-tx2/why-the-hdmi-can-t-display-gui-desktop-but-the-tty-console-is-ok-on-our-own-carrier-board-/)
and tried to pull-up and pull-down UART1-TX pin. nothing happens.
And for the USB3.0 part
nothing happened after insert a usb device.
For someone who interested in this problem we would love to share the schematic of HDMI part. Thanks
