From the project

eSPI protocol decoding accessory

This project contains open hardware design files for a debug board based on Microchip MEC1723 embedded controller which includes ARM Cortex-M4 core and eSPI physical interface. The board is designed to aid development, bring-up and integration of eSPI-based data link between servers (HPMs) and Data Center Secure Control Modules (DC-SCMs). The board has a 0.1 inch pin header connector which allows to connect it to the eSPI bus in the system under development. The board provides USB-accessible UART and JTAG interfaces, Port 80 status display and local flash storage for the MEC1723 firmware.…
