I am trying to get input from TC358743 Toshiba HDMI to CSI converter on Jetson ORIN NX.
I have installed the driver using buildKernelAndModules:
tc358743-orin.zip (25.0 KB)
I want to know what files and lines should I change in the device tree to get the video in stream. As I don’t have a result for:
sudo dmesg | grep tc358743
hello emadomari40,
there’re some popular topics for your reference.
I am trying to add the device tree file dtsi, I am getting a syntax error, my dtsi file

hello emadomari40,
may I also know what’s the syntax error reported.
it seems there’re couple of issue by went through your code quickly,
for instance,
(1) since you’re developing on Orin NX, this looks an incorrect clock definition.
(2) it’s also an incorrect GPIO API for toggle a pin.
I have actually changed the dtsi file to:
#include <dt-bindings/media/camera.h>
#include <dt-bindings/gpio/gpio.h>

I will see if it will work now!
Should I add dts file or just to include the dtsi file?
Is this still an issue to support? Any result can be shared?
I found the solutions by changing the device tree files so I am using the correct one now:
