Warning!
The switch configuration CFG B 1 OFF and CFG B 2 ON is not permitted, and may damage the Mars
EB1 base board and equipped Mars module.
Some of the configuration switches have different functions, on startup and after startup; these switches are
connected to the system controller, which reads the switch positions on startup and defines the behavior of
certain circuit elements accordingly.
When powering the system controller, the switch has the "On startup" effect; afterwards the switch can be
toggled to obtain the required hardware configuration.
Note that the system controller is powered when either a USB cable is attached, or when the main power
is applied. For example, if the application requires that BOOT_MODE1 is set to 1 and that the FTDI signal is
routed to the micro USB connector (front panel), the user should follow these steps:
Disconnect the power supply from the board
Disconnect all USB cables from the board
Configure the DIP switches for the desired boot mode
