Hi,

is there any chance to get a Hitex STM32-comstick working with openOCD ?

If not, any hints how to write a openOCD Interface for this device on my own are welcome.

I’ve already got the usb sniffer working :slight_smile:

Thanks for any answers.

Regards buffalo.

P.s. Here’s how all i know about the JTAG now.

there’s already support for the ft2232-based stm32 performancestick (according to the manual).

You may have to ensure that you have permissions on the device.

interface/stm32-stick.cfg

board/hitex_stm32-performancestick.cfg

this works for me:

sudo openocd -f board/hitex_stm32-performancestick.cfg

The STM32-comstick is not ftdi based as you can see from the usb log.

It is a hid based device and so a proprietary format, very unlikely to be supported unless Hitex release the info.

You are probably thinking of the STM32-performancestick that is ftdi based.

Ah, you’re right. I guess I have a performancestick.
