Jumper Settings
The FT 5000 EVB contains multiple sets of jumpers that you can use to configure the board. The
following sections display the locations of the jumpers on the FT 5000 EVB, show the default settings
of the jumpers, and describe how to use the jumpers to enable and disable various connections on the
board.
External Serial Non-Volatile Memory Device Connection (JP1)
This set of jumpers is used to connect an external serial non-volatile memory device (EEPROM or
flash) to the FT 5000 Smart Transceiver on the FT 5000 EVB. The FT 5000 Smart Transceiver uses
external serial memory (EEPROM or flash) to store your application code, configuration data, and an
upgradable system firmware image (the FT 5000 Smart Transceiver has no user-accessible on-chip
non-volatile memory). When a device is reset, the application code and configuration data are copied
from the external non-volatile memory into the internal on-chip RAM, and the device application is
then executed.
The external serial non-volatile memory connection on the FT 5000 EVB is enabled by default, as
illustrated in the following figure:
If you need to recover the device running on the FT 5000 EVB because it has failed, you can
disconnect the external serial non-volatile memory from the FT 5000 EVB and then reload the
application image file. To do this, follow these steps:
1. Remove jumpers 1-2, 3-4, and 5-6 to disconnect the external serial non-volatile memory from the
FT 5000 EVB.
2. Ground pin 6 on JP1. To do this, connect pin 6 on JP1 to pin 7 on JP23.
