TMS320F28388D: Use EtherCAT to achieve switch function in Mac layer

Part Number: TMS320F28388D
Other Parts Discussed in Thread: AMIC110, C2000WARE

hi expert

I have a customer want to use F28388 and AMIC110 in their servo system.

F28388 to drive the power board and AMIC110 to expand IO.

They do not run standard EtherCAT, but uses its own protocol, and only needs the switch function at the MAC MAC layer.

And the structure looks like below:

-->(port1)[F28388](port2)-->(port1)[AMIC110](port2)-->(port1)[AMIC110](port2)-->(port1)[AMIC110](port2

)

about 5 to 6 AMIC110 in their use case. And they already achieve that in AMIC110.

The reason they use this method is fast forwarding. The standard switch judges whether to forward if it receives a complete network packet. In practice, it only needs to determine whether the destination MAC address in front of the network packet is itself. If not, it can start forwarding.

here are my questions:

I want to know whether F28388 can achieve this function.

I also need to check is there an example of the switch function of the two network ports of F28388.
