Lattice Diamond crashes in Linux with MACHX03LF Starter Kit

[SOLVED] Diamond crashes when FTDI based serial interface exists on a Lattice starter kit

Page 20 of the May 2017 Lattice Diamond 3.9 Installation Notice for Linux document describes how to manually configure udev for the FTDI-based serial driver but naming the udev rule as explained in that document does not work. Below are instructions that work.

  1. Find your username which is given in /etc/group file. Log out if required. For example :

username:x:1000:

  1. Create a working file called 51-lattice.rules.

  2. Add the following information to the 51-lattice.rules file:

# Lattice - from Lattice Diamond 3.9 Installation Notice for Linux p.20 and https://github.com/jandob/lattice-diamond-archlinux showing a higher number used for the .rules file
SUBSYSTEM=="usb",ACTION=="add",ATTRS{idVendor}=="1134",ATTRS{idProduct}=="8001",MODE="0660",GROUP="username:x:1000:",SYMLINK+="lattice-%n"

# FTDI
