Udev fails to load correct Xilinx firmware

[Nils Ole Tippenhauer]

Binary package hint: udev

This is a bug report including workaround/fix taken from the Ubuntu forums (http://ubuntuforums.org/showthread.php?t=1307574)

I use a Xilinx platform cable 2 to talk to an FPGA. Before updating to 9.10, this worked based on libusb and the other components. After updating, the cable did not respond to my commands any more. Notice that all directly related configuration files were unchanged, as well as the firmware images to be loaded initiated by Udev. As suggested in the forum post, the following solved this problem: In /etc/udev/rules.d/xusbdfwu.rules, change $TEMPNODE to $tempnode. After this change, the cable behaved correctly.

I can only assume that this change was necessary due tochanges in Udev, and might affect other devices as well. This is why I am filing this bug report.

/etc/udev/rules.d/xusbdfwu.rules is listed as a custom rule file you have created, and as given in the Forums it is quite simply wrong.

[Scott James Remnant (Canonical) (canonical-scott)]

Without knowing more, it should probably look more like:

SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="03fd", ATTR{idProduct}=="0007", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusbdfwu.hex -D %N"

Thanks for the feedback Scott, I rtfm now and found it in the manpage as well. The reason why I asked was that (for me) it worked before with uppercase $TEMPNODE and after upgrading it does not any more. The original rule is provided by Xilinx, so I wanted to be sure it is their fault.
