TDA4VM: TSN support on TDA4 Ethernet Switch

Jon Bilbao

Part Number: TDA4VM

Hi,

Which TSN normative does the integrated TDA4 Ethernet Switch comply with or which TSN components does it include? We would be interested, if the following are supported

Timing and Synchronization [802.1AS-2020] (gPTP)
Credit Based Shaper [802.1Qav]
Scheduled Traffic [802.1Qbv]
Frame Replication and Elimination [802.1CB]
TSN Configuration [802.1Qcc]

These are not supported.

You can refer to this documentation for more details on how to use different TSN components with CPSW.

Hi Tanmay,

thank you for the support. Additional question related to how can we configure the GCL(Gate Control List)?

Is there any tooling support from TI side or any "standard" format you support to read our configuration tables? Or should we just follow the example in the documentation? (see: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/08_04_00_11/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSW2g.html#enhancements-for-scheduled-traffic-est-offload)

Hi Jakob,

Currently we only use taprio qdisc to configure the GCL. We don't have other standards.

Can you give me a reference to this standard you are looking for so that we can see if its better to implement it or not?
