Hi Petr Stancik, I have one more doubt , In MPC5777M MCAN Message RAM.As the message ram is shared among all the nodes,how many Maxium Std/extended id filters and Tx Buffers/RxFIFOs I can configured for each node(M_CAN_1,2,3,4).


As there are 128std id ,64extended id filter elements and 32 tx buffers ,64 rxfifo -0 and 64 rxfifo -1 available in Message RAM. I am thinking to share the all elements among all nodes. i.e out of 128 std id 32 for can-1 ,32 for 32-can2 32-for 32 for can3 and remaining 32 for can4. and same configuration for tx/rx elemments


Is it like that or I can configure total elements for each node. Can you please rectify my doubt.
