Linux USB Blaster Installation

Hi BeeGeeA

It is possible to install the USB Blaster for Linux, but you will need to change some permissions to allow users access to the USB ports (and their are some differences between distro's).

I have only done this on RHE3 and 4, but it's a similar story for SUSE etc.

(I found some instructions in a NIOS II release)

Firstly you need to set up the permissions by adding and entry to the /etc/hotplug/usb.usermap. (before plugging in your USB-Blaster.)

#

# Altera USB-Blaster

#

usbblaster 0x03 0x09fb 0x6001 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0

usbblaster 0x03 0x09fb 0x6002 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0

Then add the following script as /etc/hotplug/usb/usbblaster

# !/bin/sh

# USB-Blaster hotplug script.

# Allow any user to access the cable

chmod 666 $DEVICE

This sets up your USB-Blaster permissions so that any user can access it.

Also do a 'chmod +x /etc/hotplug/usb/usbblaster' to make the script executable.

Now you will also need to and your users to a group with permissions to use the USB ports, or do a chmod -R 557 of /proc/bus/usb

Run a jtagconfig to confirm a happy installation

Enjoy :cool:
