Hi all,

 

I have a question about flexCAN message buffer on MCF548x.

flexCAN has 16 MBs for Tx and Rx.

 

I set 14 MBs(MB#0 ~MB#13) for Rx and 2MBs for Tx.

And, I set same ID(i.e. 0x4AA) to MB#2 and MB#7.

But, when a master send a packet data, flexCAN receive the packet data via only MB#2.

 

I want to know how I can use MB#2 and MB#7 on the same ID.

 

Thanks
