Hi WayneWWW,Could you say more detail about the two output of HDMI.im a newer.
1.I dont know how to config the device tree of HDMI and the form device tree of HDMI .
2.After configing the device tree of HDMI ,how to modify the kernel source,and what is the specific file name.thank you very much!

Thank you for your reply!
When I use nv_Jetson-TX2-Series-Pinmux-Template.xlsm this file ,and click the button of Generate DT file ,but there is no file to generate .What should I do,thanks a lot!
I konw some devicetree texts ,such as /Documentation/devicetree/bindings/gpio/nvida,tegra186-gpio.text.In this text there is a example to how to config GPIO.But I dont find the text is about how to config HDMI.
I mean I dont konw how to modify the dts files about HDMI, I find the devicetree files but I dont konw how to config .Such as GPIO there is a example in the Documentation’s text ,but I dont find the example about HDMI in the Documentation’s text
Thank you very much !
On Win10 ,when I click the button of Generate DT File ,the system shows error. The error is that the macro is disabled.When I clear the error ,the dts files are generated.
Dear WayneWWW:
Generate three files by using this file of nv_Jetson-TX2-Series-Pinmux-Template.xlsm.
They are tegra18x-jetson-tx2-config-template-gpio-default.dtsi
tegra18x-jetson-tx2-config-template-padvoltage-default.dtsi
tegra18x-jetson-tx2-config-template-pinmux.dtsi three files.
But I found that they are change this part of the devicetree
host1x {
sor {
status = “okay”;
nvidia,active-panel = <&sor0_hdmi_display>;
dp-display {
status = “disabled”;
};
hdmi-display {
status = “okay”;
};
};
sor1 {
status = "okay";
nvidia,active-panel = <&sor1_hdmi_display>;
hdmi-display {
status = "okay";
};
dp-display {
status = "disabled";
};
};
nvdisplay@15200000 {
status = "disabled";
};
What should I do .
tegra18x-jetson-tx2-config-template-gpio-default.dtsi
tegra18x-jetson-tx2-config-template-padvoltage-default.dtsi
tegra18x-jetson-tx2-config-template-pinmux.dtsi three files.
Please do not put device tree change in these files. The only thing you need to do on these 3 files are using the python script to convert these dtsi files into “.cfg” files.
After this step is done, it indicates you finishes “2. Configure the pinmux through pinmux spreadsheet.”.
Then, find the correct dts files in kernel source tarball and put your change in #16 into those files.
To know which one is the “correct dts file”, please find what is the dtb file flashed into your board when running flash.sh script.
How to use the python script to convert these dtsi files into “.cfg” files.Do you have some reference files about the python script to convert these dtsi files into “.cfg” files or some examples? thank you very much !
