MEC1723 eSPI Debugger

The board is designed to aid development and bring-up of eSPI-based connections to Data Center Secure Control Modules (DC-SCMs). This debug board is based on the Microchip MEC1723 Embedded Controller.

The board connects to a DC-SCM interposer and provides USB-accessible UART and JTAG interfaces, Port 80 status display and local flash storage for the MEC1723 firmware. It can be used to develop, test and debug eSPI communication and related firmware before integrating the solution into a target server platform.
