i.MX6 - Ethernet Multicast testing

[Ansari]

Hi,

We are using imx6Q sabresd platform for our development with Linux 3.10.17_1.0.0-GA BSP.

We would like to test the Ethernet multicast testing in our target board.

Please let us know, what are the packages has to be included in the yocto file system.

In addition, please provide the steps to do the Ethernet multicast testing.

Thank You,

Regards,

Ansari

Hi Ansari

Did you get multicast working? Whenever I try to send to udp video to 239.0.0.1 I get an error. However ifconfig shows MULTICAST on the i.mx

Thanks

There is not a multicast demo or documentation for it specifically that I know of. That being said the Ethernet driver available as part of the BSP does support multicast. You can confirm if it’s enabled by looking at the information shown by ifconfig where you can see the flag MULTICAST if it’s enabled.

You may want to look at the code available on the i.MX6 SDK (link below) regarding Ethernet and RTP.

There are some examples on the web on multicast that may be of help as well. You can even find some information from other users in our communities like in the link below:

Hopefully someone on the communities can share their experience with it.
