Today I got my DE0-Nano FPGA development board. The first thing I wanted to do was get the linux connectivity setup; so I plugged it in. The device was recognized as character devide by linux right away.
Next, I checked Altera to see if anything special was needed for getting
USB-Blaster setup in linux. They recommend some
udev example rules
to make the device file world writable, I guess that is ok. I dropped the
udev rules into
/etc/udev/rules.d/51-usbblaster.rules and unplugged
then replugged the device but nothing happened.
I havent setup udev rules for a while, so right away I wasn’t able to spot the problem. I was able to test the rules using udevadm as below.
It complained that
SYSFS matchers were not valid. They were
removed in 2011 according to the udev changelog.
udevadm we are also able to see the proper attributes that we should
be matching. Below is what I have come up with to properly setup USB-Blaster
in linux. I am using Fedora 18.
My USB-Blaster udev Rules
Note, since my device is a
6001 I setup a symlink which will make it easily
Hopefully this will be helpful to other people.
