The Microchip SAMA5D3 Ethernet Development System board (EDS) board is an MPU-based platform for evaluating Ethernet switch and PHY products. Compatible switch and PHY evaluation boards connect to the EDS board via either an RGMII connector or an RMII connector. These daughter boards are available separately. The EDS board is not intended for stand-alone use and has no Ethernet capabilities when no daughter board is connected.
The SAMA5D3 EDS board comes with pre-installed Linux and Ethernet drivers. When mated to a switch evaluation board, the included software can run protocols, such as RSTP, DHCP, and PTP (1588). Users can also access registers and statistics counters in the PHY or switch, set up VLAN and other configurations in a switch, and perform traffic testing to/from the MCU. Source code is available for download from the website for this board, and users may modify and append to it for their needs.
This board is built around a Cortex®-A5-based processor on-board SDRAM and Flash memory, two Ethernet MACs (one gigabit and one 100 Mbit), three USB ports, an SD card slot, and a Serial UART interface. It is similar to the SAMA5D3 Xplained Evaluation Board (SAMA5D3-XPLD), but with the PHYs removed and replaced by the RMII and RGMII connectors. The two boards share the same development environment.
