Hi Jananisubraveti,
AN2103 is really very old, it is published in 2000, I don't have that LIN stack now, even find that driver, we still don't have the integration manual to KEA series.
KEA64 is recommended to use LIN stack "FSL_LIN_2x_STACK_PACKAGE_4.5.9", about LIN 2.X usage, you can refer to this document:
https://community.nxp.com/docs/DOC-276876
And the LIN_User_Manual.pdf in C:\nxp\FSL_LIN_2.x_STACK_Package_4.5.9\Documentation
Sorry for the inconvenience we bring you.
Have a great day,
Kerry
