Hello,

The FlexRay controller's message RAM (and other memories) are not accessible by the CPU and are not CPU memory-mapped. This is done in order to avoid conflict between the CPU accesses and the FlexRay controller message reception/transmission state machines.

CPU accesses to the message RAM are handled through input and output buffers.

Regards,
Sunil

Thanks Sunil ! But is it possible to view the IBF and OBF during Transmission and Reception of Flexray frames?
