Hi,
for SDK SW32K1_RTD_4_4_1_0_1_D2202 you would need select right LIN stack version

after succesful intallation you shoul dsee stack added in RTD folder

and on example created in RTD 1.0.1 you will have option to add this stack in Middleware section

Or you can create new example from a demo one

BR, Petr
