Programming Interface

To program the Atlys board using Adept, first

set up the board and initialize the software:

 plug in and attach the power supply

 plug in the USB cable to the PC and to

the USB port on the board

 start the Adept software

 turn ON Atlys' power switch

 wait for the FPGA to be recognized.

Use the browse function to associate the

desired .bit file with the FPGA, and click on the

Program button. The configuration file will be

sent to the FPGA, and a dialog box will indicate

whether programming was successful. The

configuration “done” LED will light after the

FPGA has been successfully configured.

Before starting the programming sequence, Adept ensures that any selected configuration file

contains the correct FPGA ID code – this prevents incorrect .bit files from being sent to the FPGA.

In addition to the navigation bar and browse and program buttons, the Config interface provides an

Initialize Chain button, console window, and status bar. The Initialize Chain button is useful if USB

communications with the board have been interrupted. The console window displays current status,

and the status bar shows real-time progress when downloading a configuration file.

Flash Interface

The Flash programming application allows .bin,

.bit, and .mcs configuration files to be

transferred to the on-board SPI Flash ROM for

FPGA programming, and allows user data files

to be transferred to/from the Flash at user-

specified addresses.

The configuration tool supports programming

from any valid ROM file produced by the Xilinx

tools. After programming, board power must be

cycled to program the FPGA from the SPI

Flash. If programming with a .bit file, the startup

clock must be set to CCLK.

The Read/Write tools allow data to be

exchanged between files on the host PC and

specified address ranges in Flash.
