Test Setup
The TIDA-00204 TI design has been tested at the testing laboratory of CSA Group Bayern in
Strasskirchen, Germany.
The TIDA-00204 with the test equipment is shown in the below picture. Each of the TIDA-00204 Gigabit
Ethernet ports 1 and 2 are connected to a PC or Laptop with an external Gigabit Ethernet to USB3
adapter. Two different test programs ran of the laptops.
The first test program "tida-00204_udp_throughput_test.exe" transmits and receives continuous UDP
packages with a payload size of 1472 bytes, yielding the maximum 1514 bytes per IPv4 packet. The
firmware of the Sitara AM3359 receives the UDP packets and echoes them back. Each of the two
Ethernet ports used around 20% of the network.
The second test program "tida-00204_udp_packet_error_test.exe" implements a UDP packet tester. It
compares the transmitted packet with the received packet (echoed back from Sitara AM3359) for the
corresponding Gigabit Ethernet port on the TIDA-00204. If a packet error is detected, it prints the number
of the packet to the console. The maximum bandwidth/network utilization achievable with this test software
was around 5% due to limitation on the PC test software "tida-00204_udp_packet_error_test.exe".
