Well, I'm fighting with openOCD, it seems to be very nice, i've installed drivers from FTDI, when i plug the module it sounds great, peripheral seems to be right installed.

But when i start the tool, it manage to list device but can't open it :(

openocd-ftd2xx -f str7xx_jtagkey.cfg

Error: ftd2xx.c:717 ftd2xx_init(): unable to open ftdi device: 2

Error: ftd2xx.c:732 ftd2xx_init(): ListDevices: 2

Error: ftd2xx.c:734 ftd2xx_init(): 0: DLP2232M A

Error: ftd2xx.c:734 ftd2xx_init(): 1: DLP2232M B

if you've got an idea, i would appreciate.

you need the following in your config script:

interface ftd2xx

ftd2xx_device_desc ''DLP2232M A''

ftd2xx_layout usbjtag

The openocd also has a forum which would be a better place to ask any related questions.

By the way, the latest version of IDEaliST from Anglia has openocd built in, so your do not have to worry about the command line options.
