AM3352 Ethernet

Other Parts Discussed in Thread: AM3352

I'm looking at the AM3352 features at a high level. It is unclear to me whether the Ethernet peripheral can be configured either as a 3-port switch (one internal port with an IP address + 2 external ports) or as two independent MACs with individual IP addresses. If so, which control register sets it up?

    Hi Jean,

    AM335x devices can be configured with dual MAC, so that both ethernet ports can be used to communicate with two differet networks.
    Following threads might be of help:

    For configuring the CPSW kernel driver to work in dual mac mode refer to the following wiki: http://processors.wiki.ti.com/index.php/AM335x_CPSW_%28Ethernet%29_Driver%27s_Guide

    Hope this helps.

    Best Regards,
    Yordan

    Hi Jean,

    Yes, both modes are possible. See section 14.3.2.10.2 in the AM335X TRM Rev. K for details on switching to Dual MAC mode.
