Hi @mayank_x30 ,
Based on the currently available information, it is not recommended to install S32K1xx SDK 4.0.x in S32DS 3.5, as we have no plans to integrate S32SDK S32K1XX 4.0.x on S32DS 3.5 or above version.
Instead, we recommend installing S32K1 RTD 2.0.x on S32DS 3.5., either online with S32DS Extensions & Updates or offline, HOWTO:offline install S32K1 RTD 2.0.0 in S32DS v3.5.
You can find this RTD version in S32K1 page >> Design Resources >> Software >>
Real-Time Drivers for S32K1 >> Automotive SW - S32K1_S32M24x - Real-Time Drivers for Cortex-M >> S32K1_S32M24x Real-Time Drivers AUTOSAR 4.4 & R21-11 Version 2.0.0
