linux and USB JTAG at Spartan 3e starter

Hi,

I have here my brand new Spartan 3e starter kit, therefore I could test
my vhdl code in real, could ...

Anyway, I'm using ISE 9.1 Sp3 Webpack for Linux and  usr-driver.so from
http://www.rmdir.de/~michael/xilinx.

As mentioned in the README udev is configured right. Plugging the USB
got in /var/log/dmesg:

usb 4-5.4: new high speed USB device using ehci_hcd and address 4
usb 4-5.4: configuration #1 chosen from 1 choice
usb 4-5.4: USB disconnect, address 4
usb 4-5.4: new full speed USB device using ehci_hcd and address 5
usb 4-5.4: not running at top speed; connect to a high speed hub
usb 4-5.4: configuration #3 chosen from 1 choice

The green LED is on.

lsubs got:

Bus 004 Device 001: ID 0000:0000

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

There is nothing new. Calling impact using as root:
LD_PRELOAD=/opt/Xilinx91i/bin/lin/libusb-driver.so
/opt/Xilinx91i/bin/lin/impact

got:

After plug off and plug in again, the green LED is off.

Kernel is 2.6.21 (debian/testing), Impact 9.1.03i.

Compiling the xilinx stuff suffers/fails from wrong kernel version depency.

Hi,

did some more tries. Writing the Firmware to the USB Controller using
fxload got:

Writing the firmware on windows flash the USB LED red, at this LED off
for about 2 sec and green again. As I understood udev on linux this
should be called automatically if the vendor ID on bus appeared:

SYSFS{idVendor}=="03fd", SYSFS{idProduct}=="0008", NAME="windrvr6"
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd",
SYSFS{idProduct}=="0007", RUN+="/sbin/fxload -v -t fx2 -I
/opt/Xilinx91i/bin/lin/xusbdfwu.hex -D $TEMPNODE"
BUS=="usb", ACTION=="add", SYSFS{idVendor}=="03fd",
SYSFS{idProduct}=="0009", RUN+="/sbin/fxload -v -t fx2 -I

SYSFS{idProduct}=="000f", RUN+="/sbin/fxload -v -t fx2 -I
/opt/Xilinx91i/bin/lin/xusbdfwu.hex -D $TEMPNODE"

Something wrong?

Thanks

Yes, as the README says, the line
ACTION=="add", BUS=="usb", SYSFS{idVendor}=="03fd", MODE="666"
is required! Now it works, huray!

Thanks

Green on a S3E starter kit means that the cypress usb firmware is
running. Did you connect the board on windows and booted to linux
without power-cycling the board?

Did you connect the board to a hub? If so, try it without the hub.
It should show up the following when the green led is off:
Bus 002 Device 009: ID 03fd:000d Xilinx, Inc.

And when the firmware is loaded (green led on):
Bus 002 Device 012: ID 03fd:0008 Xilinx, Inc.

Impact is specifically looking for an USB device with the ID 03fd:0008
and can't find it.

The flashing with red led you described in your other post is
downloading the cpld image and should only happen when you upgrade
ISE and there is a new version available.

Should work.

> Compiling the xilinx stuff suffers/fails from wrong kernel version depency.

And won't help if you do not see the download cable in the lsusb-output.

Hello Michael,

now it works, the problem was I thought that the mentioned udev line in
the readme is optional, which isn't. After adding the line it works.

Thanks
Olaf
