AM3354: Whether multicast and etherCAT can be supported at the same time

Ethan Tian

Part Number: AM3354

Hi experts

My customer cannot receive multicast packets on the A8 platform Ethernet port, and after the CPSW_dual_MAC_mode macro definition is canceled, they can receive multicast data, but the EthercatCAT port is not available at this time.

I want to ask if there is an Ethernet-driven configuration that supports multicast and EtherCAT at the same time

Hello Ethan,

Is your customer using the Linux SDK or RTOS SDK?

Thanks,

Jianzhong

Hi Jianzhong

RTOS SDK

They use one of the Ethernet port as etherCAT port, the other one is used for multicast data incoming.

If they remove the CPSW_dual_MAC_mode macro definition, multicast reception is normal

What should do to configure the two ports to work simultaneously?

Hello Ethan,

Jianzhong is on vacation until after Thanksgiving, so responses will be delayed.

To confirm, the customer is using CPSW Ethernet, right? Not PRU Ethernet?

Regards,

Nick
