If it's possible to configurate two flexray key slot in MPC5748G/C?

To make sure an ECU with MPC5748G/C is able to wakeup a TT-L cluster(only two flexray node in the cluster, another node is a non-sync node) ,  pSecondKeySlotID and pTwoKeySlotMode should be supported by MPC5748G/C.

Hi,

I'm not FlexRay expert but the module on MPC5748G is designed according to FlexRay 2.1 Protocol Specification. This one talks only about pKeySlotId.

pSecondKeySlotID is specified in FlexRay 3.0.1 Protocol Specification.

So, the answer should be that this is not supported by MPC5748G.

Hope this helps.

Regards,

Lukas

Hi Lukas,

Thank you for your reply.

MPC5748G can be repalced in our project. But the new chip should be very similar to MPC5748.

Is there any other alternative chip that support FlexRay 3.0.1 ?

Only FlexRay 2.1 is available on current MPC5xxx and S32 devices.
