Hi,
Thank you so much for your interest in our products and for using our community.
There is no more SDK updates. Now we provide Real Time Drivers (RTD). You can found them in the following way:
For S32K1, please go to Design Resources -> Software -> Real-Time Drivers for S32K1 -> Automotive SW - S32K1_S32M24x - Real-Time Drivers for Cortex-M
For S32K3, please go to Design Resources -> Software -> S32K3 Standard Software -> Automotive SW - S32K3/S32M27x - Real-Time Drivers for Cortex-M
The latest RTD version for S32K1 is the patch S32K1_S32M24X Real Time Drivers AUTOSAR R21-11 Version 2.0.0 P04, however you need to install the S32K1_S32M24X Real Time Drivers AUTOSAR 4.4 & R21-11 Version 2.0.0 before.
The latest RTD version for S32K3 is the S32K3_S32M27x Real-Time Drivers ASR R21-11 Version 5.0.0.
At the moment both of them are fully tested in S32DS 3.5. Please follow the installation flow of each RTD in its respective release notes.
Hope it helps you.
Have a nice day!
