Hi,

I have a question about AM335x Ethernet.

I want to use AM335x Ethernet subsystem as Hub.

Is this hardware able to function as Hub?

I want to connect 2 port of Ethernet by daisy-chain.

If it can't support by hardware, is there any way to support by software?

best regards,

Hi g.f,

The AM335X CPSW supports packet forwarding. See this wiki for details: http://processors.wiki.ti.com/index.php/Linux_Core_CPSW_User%27s_Guide

Hi Biser,

Thank you for the reply.

I'm sorry but can you please explain little bit more?

Do you mean that AM335x Ethernet Subsystem can function as Hub because CPSW supports packet forwarding.
Is it correct?

Ether Port1 and Port2 can be connected via CPSW and if packet data come into Ether port1,
this packet will move into Ether port2 by hardware(CPSW), am I right?

best regards,

The AM335x contains a store and forward switch which is quite different from a hub. Depending on how the ALE is configured packets will be forwarded based on the ALE learning where the destination port is.
