DRA821U: How to add multiple multicast addresses to the cpsw9g switch of TDA4?

buaawkp

Part Number: DRA821U

Hello, TI expert.

According to the method in this post, we have successfully added the multicast function.

DRA821U: how to configure ALE policy to forward multicast packets from specific CPSW9G external port to A72 (Don’t need to send to other R5F’s)? - Processors forum - Processors - TI E2E support forums

But there are the following 2 problems:

1. After setting up according to this method, we cannot send and receive broadcast data;

2. If I want to add multiple multicast addresses, how can I do it? Can I call the CPSW_ALE_IOCTL_ADD_MCAST command twice to add 2 multicast addresses?

Hi,

Sorry for the delay.

Are you trying to send broadcast data to A72 ? Broadcast requires a separate entry. See this E2E for reference

Yes, create an entry for each Multicast
