I just bought a Olimex JTAG TINY programmer.

I plug it into my PC, the PC finds a Olimex OpenOCD JTAG TINY.

BUT windows cannot auto install a driver, and when I point to the Open OCD driver directory, windows responds with 'Cannot install hardware - cannot find driver'

This is not helping me!

WinXP

Thanks

Where did you get your OpenOCD your and what version is it?

I suggest getting your OpenOCD from :- http://www.yagarto.de/

Good Luck.

Hi,
before you plug the ARM-USB-TINY you should have run the install CD

I did run the install CD first before I plugged it in, it was supplied with the programmer.

Considering it was supplied with the device I would expect it to work.

I dont know what to do next. I have tried removing drivers and software, re-installing software and plugging it in again. Still says cannot install hardware. My Atmel ISP works fine in the same USB port.

I managed to install the drivers (by using a different PC).

But I still havent worked out how to use it yet.

When I try to run OpenOCD Tiny, I get errors (unable to find ftdi device)

This is anoying, because USB VIEW can see the dongle, and Hyperterminal can see it as COM7.

I tried editing the config for the OpenOCD Tiny as it had wrong VID/PID. It made no difference.

"Info: openocd.c:82 main(): Open On-Chip Debugger (2006-10-12 18:00 CEST)

how come VID/PID values are wrong?
can you tell us your "correct" VID/PID values you set?

The ft2232_vid_pid setting is only used on Linux/BSD/etc., but not on Windows. On Windows the VID/PID is determined by the driver during installation.

Try setting the ft2232_device_desc to "Olimex OpenOCD JTAG TINY A"

Hi all,
I have the same problem on Windows Vista. I'm using openOCD 204, ARM-USB-TINY. Here's what I get:

Error: ft2232.c:1341 ft2232_init_ftd2xx(): unable to open ftdi device: 2
Error: ft2232.c:1356 ft2232_init_ftd2xx(): ListDevices: 2

Error: ft2232.c:1358 ft2232_init_ftd2xx(): 0: Olimex OpenOCD JTAG TINY B
Error: ft2232.c:1358 ft2232_init_ftd2xx(): 1: Xš:

This is the part of the config that matters:
#interface
interface ft2232
ft2232_device_desc "Olimex OpenOCD JTAG TINY A"
ft2232_layout "olimex-jtag"
ft2232_vid_pid 0x15BA 0x0004

jtag_speed 20

What is the solution?

Thanks,
Gil
