3rd Party/Other Boards and Kits

[bast]

I wanted to try the digilent spartan-3e kit that on my linux machine. So I installed the complete toolkit (including drivers). But my machine doesn't recognize the board. After a bit of trial and error if found out that the idproduct changes.

When i turn the board off, plug it in to my linux machine and turn it on.

lsusb: Bus 001 Device 019: ID 03fd:000d Xilinx, Inc.

When i do the same on windows(on my laptop)

USB\VID_03FD&PID0008.

So windows sees 0008 and linux 000d.

If i swap from windows to linux, without toggleing the power, linux also sees

0008 Bus 001 Device 020: ID 03fd:0008 Xilinx, Inc.

The board works fine till i toggle the power. Then i first have to connect it to windows to get it running again.

I have almost zero experience with udev, so i don't really know where i have to look.

I fixed it.

There were some problems with the udev rules. The rules are for older versions of udev. The way i found out.

[code]

sudo udevadm control --log-priority=debug  # set the log to debug

sudo tail -f -n100 /var/log/daemon.log # tail the log

[/code]

The log file stated that there were some problemes with the udev rules.  The rules have to be like this:

SUBSYSTEM=="usb", ACTION=="add", ATTRS{idVendor}=="03fd", ATTRS{idProduct}=="0015", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xse.hex -D $tempnode"

instead of:

BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0015", RUN+="/sbin/fxload -v -t fx2 -I /usr/share/xusb_xse.hex -D $TEMPNODE"
