Turn On or Off the Console

By default the Linux console is disabled to improve performance and to prevent any display artifacts between application transitions. To re-enable the console do the following:

  1. Connect a serial cable board

  2. Interrupt the U-Boot startup sequence

  3. env edit console

  4. Switch ttymxc1 to ttymxc0

  5. env save

To disable the console, repeat the above steps but instead switch ttymxc0 to ttymxc1.
