Virtual UART Usage

1. Launch ISD tool with an Intel® DCI debug connection

2. There are two ways to enable the virtual console:

   1. Enable the virtual console in the target connection configuration by selecting the “Enable Virtual Console” checkbox as shown below:

   

   2. Alternatively, the virtual console can be started from the command line with the following commands:

      cons = tca.TcpConsole(8,4, "localhost", "8282")
      cons.start_async()
      

   Note:

   Parameters of “tca.TcpConsole”: - 1st and 2nd parameter: read & write mailbox of the OpenIPC - 3rd : IP address of debug host or use “localhost” - 4th: TCP port number

3. Run the terminal emulator (e.g. Putty)

• Give the localhost in “Host Name” and 8282 as the port number

• Select a Telnet as the “Connection Type”

4. Open the “Options controlling the terminal emulation” under the “Terminal” category and select the Force Off for the “Line discipline” of both local echo & line editing

5. To use special characters on the terminal emulator:

• Open the “Keyboard” option under the “Terminal” group

• Select Control-H for the “Backspace key”

• Select SCO for the “Function keys and keypad”

6. Open the “Window” to adjust the column of the emulator

• Change the “Columns” field to 80 and “Rows” to 20 (It is default for BIOS setup in a screen and please adjust those values according to your BIOS screen resolution)

7. Select “Open” at the bottom of the configuration and use virtual UART with Putty terminal

• The following screenshot is a typical view of “EFI Shell” over virtual UART

Note:

User can use another terminal emulator that would open the specific TCP port. Please check if the BIOS has a DCI-IO driver which conveys UART message over Intel® DCI.
