41.9. tsn_stmid_frer_ingress

41.9.1. Overview

This example shows TSN frame identification and redundant transmission (IEEE802.1 CB)

• Observe the result of the frame identification

  • After frame passes a successful identification, a incremented sequence number will be generated by STMID module, and then a R-Tag will be added by FRER module.

• Redundant Transmission can be implemented by multi-cast mechanism

  • Due to the limitated hardware design of the development board, this feature is not shown (There is no frame splitting functionality in TSW peripheral. )

• At the receiving end, run the sample tsn_stmid_frer_egress on another development board and observe the results of frame recovery

41.9.2. Board Settings

• Connect a USB port on PC to the PWR DEBUG port on the development board with a USB Type-C cable

• Connect an Ethernet port on PC to a RGMII port on the development board with an Ethernet cable

41.9.3. Project Configurations

• None

41.9.4. Run Example

• Compiling and Downloading

• Running log is shown in the serial terminal as follows:
