    Get UART right after board reset

    Tom Cheng

      Hi friends,

       

      The situation I've got is:

       

      -- On my Intel Joule board, I can immediately get UART working after the board resets.  So I can even configure BIOS from my minicom.

      -- However, the above doesn't work on my aero board. The minicom won't be active until the Linux on the board finishes booting.

       

      I wonder:

      -- What makes this difference?

      -- I found an option in the BIOS: Setup Utility -> Advanced -> Console Redirection -> Terminal Type. The default value is VT_100. Should I change it to PC_ANSI? I hesitated to try this out coz I don't want to redirect my console to somewhere I don't have access to...

       

      Thanks a lot!

      Tom.
