Hi,

I have been searching for the LT9211C driver for Jetson Xavier NX. I found the LT9211C driver for JetPack 6, but there is no driver for JetPack 5. Could you please direct me to the appropriate driver?

Please tell me this also, why are we integrating the driver under the DRM folder instead of the Media folder?

Thanks in advance.

Hi,
Jetpack 5 is Kernel 5.10. Please check with the vendor whether they have driver for the kernel version.

Hi,

They given driver for kernel 5.10. In that driver there is no parse_dt function and some other nvidia driver function informations are missing.
Is there any other way to find the driver which is compatible for nvidia?

Hi,
It seems like the driver is in upstream kernel. On Jetpack 6, the kernel version is 5.15. Please share path to the driver code.

Hi,
You have mentioned I found the LT9211C driver for JetPack 6. So if we follow the steps to extract kernel code:

Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation

Please share the path to the LT9211C driver. The kernel version of Jetpack 6 is 5.15 and would like to know where it is or how you enable it.

Hi,

I have shared the link given below.

But this is for different process. My application is LVDS to MIPI. It is different. If I take jetpack 6 also, How can i modify the driver characterisation?

Hi,
We would suggest check with the vendor for porting the driver to previous kernel. The driver code is new and it even does not exist in K5.15:
