CouthIT’s 5-Port Learning Industrial Ethernet Switch is industry’s first such implementation on the TI Sitara AM572x platform. It has been successfully deployed on the field and has achieved PROFINET compliance.
- Uses 1 MAC and 1 IP address to implement the 5-port switch.
- Uses all the 4 PRU ports on the TI AM57xx Sitara platform.
- The 5th port is the ARM host core providing immense flexibility to develop custom applications as well as managing the 4 PRU ports.
- Supports 100 Mbps throughput across all the four ICSS PRU ports.
- PRU firmware compliant to IEEE 802.1 Ethernet Standards.
- Each port has dedicated queues thereby avoiding all queue contention related complexities resulting in improved performance.
- Support for storm-prevention.
Support for per-port statistics. - Support for learning on all 4 ICSS PRU ports.
- Can also be customized to work as two 3 Port Ethernet Switch with the ARM host core being the common port.
- Validated on the TI Sitara AM572x IDK
- Throughput testing for unidirectional and bi-directional traffic across all the 4 PRU ports.
- Tested using unicast, multicast and broadcast packets across all the four PRU ports.
- Tested for QoS by sending packets with different priority levels.
- Tested to verify learning on the host and PRU ports.
- Tested to verify the statistics generated by the PRU ports are correct.
- Tested to verify that the local-link frames are not forwarded by the switch.
