== Boot mode selection ==
The following sections detail how to select the boot option depending on the adapter's revision.
S1 is a 2-way dip switch for the boot mode selection (PIN: BOOT_MODE_SEL). The following table reports the available configurations for the two Axel Lite models. For further details, please refer to [[Boot_options_(AxelLite) | Axel Lite boot optionsthis page]], which describes the available boot modes thoroughly. === Boot from SD/NAND Revision 0===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.{| class="wikitable" |-+!Switch rowspan="2" |Axel Lite type!Position!Functioncolspan="2" |S1.2!Notesposition

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===
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.
=== Boot from SD/SPI The selectable 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.
