Hi,
I have Jetson Xavier nx .
In L4T 35.5.0 I used ArduCAM driver : GitHub - ArduCAM/MIPI_Camera
By installing this driver on my board I can recording 12Mpixel. after installing this driver, device tree is changed to support 12Mp resolution.
But I want work by L4T 35.6.0 .
In 35.6.0 must be change device tree to add support 12Mpixel 4032x3040 resolution.
Please Help me.
Thanks.
You need to add the mode in driver and device tree for it.
Thanks
Hi,
I wrote new device tree overlay to support 12M pixel.

but to adding 12M pixel in driver, I need to know the camera registers value for this mode.
I google for IMX477 full datasheet, but I can’t find a document describe imx477 registers.
Are Nvidia have a solution to capture 12M pixel from imx477 cam?
Are you have a complete datasheet or technical reference for imx477?
Thanks.
Please consult with Sony.
Thanks
