About AM437x EtherCAT master

g.f.

Hi,

I have a question about Sitara AM437x.

AM437x will act as EtherCAT master.
It will communicate with many EtherCAT slaves in the system.
I want the final EtherCat slave line to be return to EtherCAT master(AM437x).
In this case which peripheral can be used in AM437x?
Please see the attached file to know what I want to do.

best regards,
g.f.

Hi,

CPSW IP available on AM437x is not a GMAC but a switch, it has 2 physical ports and 1 host port and can be configured in DUAL MAC mode for EtherCAT master with redundancy support.

Hi Pratheesh,

Thank you for the reply.

So, it is possible to do what I want if I use DUAL MAC mode.
By the way, is there any sample program for EtherCAT Master?

best regards,
g.f.
