==Boot configuration==
As described [[Boot_process_and_bootstrap_configuration_(AXELULite)|here]], ''GPIO ovverride'' mode is extremely helpful when it comes to select different boot configuration options. AXELULite adapter provides a bank of switches that allows to change both <code>BOOT_MODE</code> and <code>LCD1_DATAx</code> signals affecting boot configurations. When the switch is in ON position, "10" logic level is selected.
The following table lists all the switches in detail.
