How do I enter bootloader menu?

I want to enter the bootloader menu in order to to enable the debug output. I followed the instruction provided on this website. I pressed the “space”-key but the boot process was not stopped to enter the bootloader menu.

Make sure you considered the following points:

  • Press the “space”-key on the serial terminal, not on keyboard you have attached to your Toradex device.
  • Some terminal Tools do not send the characters fast enough. We made good experience with TeraTerm.
  • Make sure you have set up the correct baud rate.
