EVB configuration
This section provides information on how to configure the jumper settings on the EVB. Default settings
are marked as such.
4.1
Methods of operation
Power to the EVB is supplied by one of two options:
1.
The
MPC57XXXMB
main board generates the 5
V/3.3 V/1.25
V supplies and provides these to
the
EVB via the interface connectors.
2.
In standalone configuration, external 5
V/3.3
V/1.25
V supplies are provided to the EVB via the
terminal block. (This option provides minimal access to I/O)
4.2
Power source
The default jumper settings are configured for using the EVB with the
MPC57XXXMB
main board.
Power is supplied from the main board to the EVB via the two interface connectors.
The EVB can also operate as a standalone device, where power can be supplied from an external power
source.
