This adapter provides a switch that allows selecting the boot device according to the following table. The available boot options differ depending on the Axel Lite type. In this regard, there are basically two types: those that are equipped with both NOR and NAND flash, and those that are equipped with NAND flash only.

It is worth remembering that, when using Axel Lite in combination with AxelEVB-Lite revision 0, the S5, S6, S7, S8, and S9 switches of the carrier board don't affect the boot options.

Revision A does not integrate any switch. To select the boot source, please use the S9.2 switch provided by the [[AxelEVB-Lite#Boot_configurations|AxelEVB-Lite rev. A]] board instead.

Introduction[edit | edit source]

Axel Lite requires a dedicated adapter to be plugged to the AxelEVB-Lite carrier board. This adapter:

  • provides the SODIMM socket for the AxelLite SOM
  • provides the following additional features:
    • microSD slot (for SD boot)
    • JTAG connector
    • dip-switch for boot mode selection
  • routes the signals from the AxelLite pins to the AxelEVB-Lite mating connectors

The following images show the top and bottom views of the AxelEVB-Lite-Adapter:
