Project Evaluation

Idea: See if a board/software under 10.euros, can be made for low cost commercially available FPGAS or CPLDs using as a base, the already known hacks done with FPGAs that allow to reuse LCDs that compply to the MIPI industry Standart.

REFERENCES:

The Digilent JTag uses FT2232, but its configuration EEPROM contains secrete data needed to be recoginzed by Xilinx ISE/Vivado. The following method only works on linux (tested on Ubuntu16.04), but the patched FT2232 doggle also works on Windows. Since WSL1 does not provide USB device access, the following method will not work for WSL1.

DONT use FT_Prog on offical Digilent cable, as it can trash the firmware! The offical eeprom contains secrete data that cannot be handled correctly by FT_Prog.

Here are steps to create a Digilent-like Jtag that can be used in Xilinx ISE and Vivado

Install softwares: sudo apt-get install libftdi1 ftdi-eeprom
Create a file "flash_digilent.conf" with the following content:

	#!/bin/bash -e

	router_ip="192.168.1.1"
	user="admin"
	password="<check_your_password_in_the_sticker_behind_your_router>"


	cookie_jar="$(mktemp)"
	cleanup() { rm -f "$cookie_jar"; }
	trap cleanup QUIT
