Boot modes can be selected by S1 DIP-switch which act acts directly on BOOT_MODE[02..20] configuration pins.

S1 switches are mapped connected to [[ETRA_SOM | ETRA]] BOOT_MODE[2:0:2] pins allowing different boot modes.

The different [[File:ETRA_SBC-S1-boot modes can be found in the following table:-switch.png | 400px|thumb|center| S1 boot switches]]

'''DA RIVEDERE'''where S1 switches are mapped as the following table: {| class="wikitable" ! latexfontsize="scriptsize" | BOOT_MODE! latexfontsize="scriptsize" | S1! latexfontsize="scriptsize" | Note|-| BOOT_MODE0 || S1.1 || |-| BOOT_MODE1 || S1.2 || |-| BOOT_MODE2 || S1.3 || |-| - || S1.4 || USB OTG settings|-|}
