Setting up the FPGA
All DAG cards have at least one Field-Programmable Gate Array (FPGA). The FPGA contains the firmware
for the installed DAG card. The firmware defines how the DAG card operates when capturing data and
contains the specific configuration.
For the FPGA on the DAG 9.2X2 there are up to four firmware images stored in ROM:
•
The factory image - contains fixed basic functionality for operating the DAG card. It cannot be
overwritten by the user.
•
The user images in slots 1 to 3 - User image #1 is programmed at the factory. Other user images
may or may not be pre-programmed. User images can be updated by the user either to update to a
new release, or to load an user image with different functionality than that originally shipped from
the factory.
By default, the DAG 9.2X2 card boots using the
user image in slot 1
, unless the Force Factory jumper
is fitted. For more details on the Force Factory jumper, see
Boot jumper settings
(page 11).
Booting from the factory image is only required if the DAG card cannot boot from any of the user images
as a result of a ROM programming error.
