AM6411: Does it support TSN?

Bart

Part Number: AM6411

Hello,

we need a processor with 1x Gigabit ETH mac, and support for TSN. Looking for the lowest cost options currently.

Does the AM6411 support TSN (perhaps on CPSW2G)?

Thanks.

    Yes, all part numbers in the AM64x family support 1G TSN, AM6411 is the entry point device. Specific TSN features supported in CPSW3G of AM64 family are:

    Dual Multi MAC mode, traditional 2x Ethernet port 10M/100M/1G

    Multi port Switch mode, IEEE 802.1Q-2018 VLAN aware wire rate 1G switch, 2 external ports. Cut-through supported, configurable per queue (VLAN priority). Ethernet LAN will look like 1 MAC port to Linux, same commands as with a virtual bridge in Linux, just the bridging is offloaded to hardware.

    802.1AS-2011 using Common Platform Time Sync (CPTS) module and linuxptp. 802.1AS-2020 can also be supported by the HW, stack is not included in SDK.
    802.1Qbv Enhancements for Scheduled Traffic (EST) Offload
    802.1Qbu / 802.3br Intersperse Express Traffic (IET) Frame Preemption offload
    802.1Qav Forwarding and Queuing Enhancements for Time-Sensitive Streams (FQTSS, 802.1Qav)

    Further some capabilities for 802.1Qci filtering are supported.

    Linux documentation is at:

    R5 freeRTOS support coming in later releases.
