Virtual UART over Intel® DCI

A typical debug connection of ISD is established using the OpenIPC over Intel® DCI (Direct Connection Interface)-based debug cable. Not only OpenIPC connections but many BIOS developers are also using UART connections to run UEFI shell or change BIOS settings with the BIOS setup menu. The virtual UART feature emulates this UART connection over an OpenIPC connection.

Prerequisites:

  • The BIOS has DCI-IO driver for redirecting UART messages over Intel® DCI(Direct Connection Interface) connection.

Note:

The DCI driver is included in Intel® reference BIOS of Panther Lake platform.

  • Terminal emulator which opens the TCP port to communicate with ISD and renders UART message with “Telnet” protocol.
