The following items are supported in the Gateworks U-Boot for Malibu:

  • eth0 (RGMII)
  • USB Host mode (USB Mass Storage and USB Networking for various USB Ethernet adapters supported by U-Boot
  • eMMC / microSD

The following items are not currently supported in the Gateworks U-Boot for Malibu:

Restoring defaults

The Malibu boot firmware has a copy of the original U-Boot env that was created during build time.

To restore default bootloader environment variables:

  • At the "Hit any key to stop autoboot:" prompt press any key.
  • Execute the following command:
    run restore_env && reset

Editing the environment

If you would like to modify the default environment you can edit the malibu.env in the Malibu BSP.
