Could you provide two the picture clearly to us?
Thank you very much!

Hi, @kayccc :
OK, thanks.

In the other hand, the document mention to tca9546@70 in the GSML device tree programming part(tegra194-p2822-0000-camera-imx390-a00.dtsi).
But I can’t find the tca9546 driver code in the L4T driver package.
Could you release the GMSL code patch?

I had found the TCA9546 driver code in

Suppose the i2cmux is design on the camera board. Have a check the camera design guide from download center.

Ok, Thank you


In the other hand, I see the GMSL reference module in online document.
But what’s the module number of GMSL reference module(include MIPI adapter board, MIPI white cable, MAX9296 deserializer board, GMSL coax cable, IMX390 sensor, MAX9295 serializer pair modules)?
How to buy it?

Looks like this design is from camera partner Leopard.
Maybe consult with Leopard would be better.

Could you check for this HW design.
