Configuration

After power-on, the

FPGA on the Atlys

board must be

configured (or

programmed) before it

can perform any

functions. The FPGA

can be configured in

three ways: a USB-

connected PC can

configure the board

using the JTAG port any

time power is on, a

configuration file stored

in the SPI Flash ROM

can be automatically

transferred to the FPGA

at power-on, or a

programming file can be transferred from a USB memory stick attached to the USB HID port.

An on-board mode jumper (JP11) selects between JTAG/USB and ROM programming modes. If JP11

is not loaded, the FPGA will automatically configure itself from the ROM. If JP11 is loaded, the FPGA

will remain idle after power-on until configured from the JTAG or Serial programming port.

Always keep JP12 loaded (either on 3.3V or 2.5V). If JP12 is not loaded, bank 2 of the FPGA is not

supplied, and neither are the pull-ups for CCLK, DONE, PROGRAM_B and INIT_B. The FPGA is

held in the Reset state, so it is not seen in the JTAG chain, neither can be programmed from the serial

FLASH.
