The following table reports available boot options differ depending on the connector's pinoutAxel 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" |-+!Pin# !Pin name!Function!Notes|-|1 ||SD1_DAT2||| DATA[rowspan="2] |" | -Axel Lite type|-|! colspan="2 " ||SD1_DAT3||| Card Detect/DATA[3] || -|-|3 ||SD1_CMD||| CMD line || -|-|4 ||ADP_3S1.3V||| Power Supply || -|-2|5 ||SD1_CLK||| Clock || -|-|6, 9, 10, 11, 12 ||DGND||| - || -position

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 mode selection ==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.
S1 is a 2-way dip switch for the boot mode selection. The following table reports the available configurations: {| class="wikitable" |-+!Switch rowspan="2" |Axel Lite type!Position!Functioncolspan="2" |S9.2!Notesposition
