hi,A_VIJAYA7

You can find the LIN demo in the RTD.  The RTD demo installed to the S32DS IDE as the shown following picture.

I am working with the S32G-VNP-RDB3 Reference Board using the Yocto-based Linux BSP (penEmbedded/Yocto Linux BSP for NXP Auto platforms). I would like to:

Linux is up on my board, I want to Develop a userspace application to communicate through LIN interface on Linux.
Could you please help with the following:

What are the required Linux APIs or interfaces (e.g., character devices, ioctl, sysfs, etc.) to access and control the LIN interface from userspace?
Are there any example codes or reference applications available for LIN communication in userspace on this platform?
Any specific device tree configurations or kernel modules that need to be enabled for LIN support?
Thank you for your support.

hi，A_VIJAYA7

Thank you for your reply.

Refer to the BSP User Manual, Linux BSP can configure LINFLExD channels to be used in UART mode exclusively, you should modify the n <builddirectory>/conf/local.conf file to do it as the shown the following picture.

You also can find some document and drivers in Kernel.
