Arty-A7 board

The Arty-A7 board allows testing its on-board DDR3 module. The board is designed around the Artix-7™ Field Programmable Gate Array (FPGA) from Xilinx.

The following instructions explain how to set up the board.

Board configuration

Connect the board USB and Ethernet cables to your computer and configure the network. The board’s IP address will be 192.168.100.50 (so you could e.g. use 192.168.100.2/24). The IP_ADDRESS environment variable can be used to modify the board’s address. Next, generate the FPGA bitstream:

export TARGET=arty
make build

Note

This will by default target Arty A7 with the XC7A35TICSG324-1L FPGA. To build for XC7A100TCSG324-1, use make build TARGET_ARGS="--variant a7-100"

The results will be located in: build/arty/gateware/digilent_arty.bit. To upload it, use:

export TARGET=arty
make upload

Note

By typing make (without build) LiteX will generate build files without invoking Vivado.

To save bitstream in flash memory, use:

export TARGET=arty
make flash

Bitstream will be loaded from flash memory upon device power-on or after a PROG button press.
