TUMPA - OpenOCD

vancv

Hi,
I bought TUMPA yesterday, now it's on the way.

I would like to know how to debug uCs (ARMv7) with TUMPA using JTAG. I can't find any information about it, nor config file for OpenOCD. But it should be fully supported. Can anybody explain to me how to use OpenOCD with TUMPA?
Ragards,

Hi, thanks for purchasing TUMPA.
This is the openocd file:
Here you go:

ft2232_device_desc "TUMPA TIAO USB Multi-Protocol Adapter"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0x8A98

EDIT by volkan-k on June 27, 2013;
Using a config file for jtagkey can result in a permanent damage for your TUMPA. Please get the current OpenOCD version from git instead, build with ./configure --enable-maintainer-mode --enable-ftdi; make; make install and use "-f interface/ftdi/tumpa.cfg" when running openocd.

I bought the TUMPA and would like to use it with OpenOCD, but did not understand where should I put the configuration file mentioned in the topic:
http://www.tiaowiki.com/forums/index.php/topic, 4016.0.html
I get the error "Unable to open FTDI device: device not found"
I saved a file in the folder named tumpa.cfg board. I find no file named ftdi.cfg folder interface.
What is the detailed procedure for using TUMPA with OpenOCD?

do you see it in device manager?
Thanks

I am also having some trouble detecting the device in Ubuntu.
Using lusb the device shows up as
Bus 001 Device 004: ID 0403:8a98 Future Technology Devices International, Ltd
But when i run
sudo openocd -d 1 -f tumpa.cfg -f board/ti_beagleboard.cfg
openocd with the posted tumpa.cfg file above i get:

Try following config if your device pid is 0x6010 .;
