Hi @mohanagv,
It is fine to use both AUTOSAR and non-AUTOSAR drivers in the project, but there are some limitations when mixing them:
1. It is forbidden to use the same hardware instance in HLD and LLD (E.g. if SPI1 is used in HLD context, it cannot be used also through IPL)
2. IP layer doesn’t provide Tresos configuration. It can be configured only on Design Studio (CT).
3. IP layer cannot be used in AUTOSAR applications, as it does not satisfy ASR compliance constraints (DEM, DET, Multicore). IP layer should not be seen as a CDD.
Best regards,
Julián
