3.2.3.8. TSN with CPSW

3.2.3.8.1. Introduction

TI Common Platform Ethernet Switch (CPSW) supports TSN features such as:

1. PTP (Precision Time Protocol) [IEEE-1588, IEEE-802.1AS]
2. EST (Enhancements for Scheduled Traffic) [IEEE-802.1Qbv]
3. FQTSS / CBS (Credit Based Shaper) [IEEE-802.1Qav]
4. IET (Interspersing Express Traffic) [IEEE-802.3br, IEEE-802.1Qbu]

3.2.3.8.2. Testing Details

• The tests have been performed on TI’s J7VCL with CPSW5G in QSGMII/SGMII modes and on TI’s AM625-SK with CPSW3G in RGMII mode.
• TI’s AM64-SK with CPSW3G in RGMII mode has been used to assist in the testing process.
• TSN testing has been done in MAC mode as well as SWITCH mode.
• The test setup and the scripts are documented in this page to help replicate the tests with appropriate changes if required.
• The outputs for each of the performed tests have also been documented.
• For all the tests, CONFIG_TI_K3_AM65_CPTS has to be enabled in kernel config.
• For additional information, refer Common Platform Time Sync (CPTS) module
• For tuning the TSN features in Switch Mode, refer TSN Switch Tuning Guide
