ADM-PCIE-8V3 User Manual
The Lockdown function of the Flash device is controlled via switch SW1-2. When SW1-2 is OFF, any blocks in
the Flash whose Lockdown flag is set are write-protected. The factory default for the Lockdown flag of all Flash
blocks is clear, so that any block in the Flash can be written.
3.10.1.1 Custom Flash Write Interface
Alpha Data's reference design bridge allows users to write images to the BPI configuration flash over the PCIE
interface. Other customers may want similar functionality built into their own IP. In order to enable this
functionality, users must reference the FLASH* pins in
Complete Pinout Table
and utilize the STARTUPE3
primitive to control certain dedicated configuration pins (i.e. D0-D3). Complete details on the STARTUPE3
primitive can be found in Xilinx UG570.
3.10.1.2 Building and Programming Configuration Images
Generate a bitfile with these constraints (see xapp1220):
•
set_property BITSTREAM.GENERAL.COMPRESS {TRUE} [ current_design ]
•
set_property BITSTREAM.CONFIG.EXTMASTERCCLK_EN {DIV-1} [current_design]
•
set_property BITSTREAM.CONFIG.BPI_SYNC_MODE {TYPE1} [current_design]
•
set_property BITSTREAM.CONFIG.UNUSEDPIN {Pullnone} [current_design]
•
set_property BITSTREAM.CONFIG.OVERTEMPSHUTDOWN Enable [current_design]
•
set_property CONFIG_MODE {BPI16} [current_design]
•
set_property CFGBVS GND [ current_design ]
•
set_property CONFIG_VOLTAGE 1.8 [ current_design ]
Generate an MCS file with these properties (write_cfgmem):
•
-format MCS
•
-size 128
•
-interface BPIx16
•
-loadbit "up 0x0000000 <directory/to/file/filename.bit>" (failsafe location)
•
-loadbit "up 0x2000000 <directory/to/file/filename.bit>" (default location)
Program with vivado hardware manager with these settings:
•
BPI part number: mt28gu01gaax1e-bpi-x16
•
State of non-config mem I/O pins: Pull-none
•
RS bits: 25:24
3.10.2 Configuration via JTAG
A micro-USB AB Cable may be attached to the front panel USB port. This permits the FPGA to be reconfigured
using the Xilinx Vivado Hardware Manager via the integrated Digilent JTAG converter box.
3.11 GPIO Option
The ADM-PCIE-8V3 has an optional GPIO feature. This feature is not fit by default and must be specified in the
part number. See
Order Code
for more details on ordering options.
The GPIO option consists of a versatile shrouded connector from Molex with part number 0878331220 that give
users with custom IO requirements multiple connectivity options. The connector houses two types of signal,
direct connect to FPGA signals and low speed serial communication signals.
Recommended mating plug: Molex 0875681273
