Hi!
I have Arm-usb-tiny and arm-jtag-swd. I need to debug/flash nrf51822 chip using SWD. I'm using openocd 0.9.0, windows 8.1 x64. I tried WinUsb driver from zadig. SWD did not work. I tried different d2xx drivers and ftdi profile and I received LIBUSB_ERROR_NOT_FOUND. So which drivers do I need to use with openocd 0.9.0 and SWD?
Thanks
Stay away from d2 stuff and only use recent ftdi (if any), not older ft stuff.
Other than that, if no luck post details on oocd ML.

I don't think so.
oocd goes via USB packets. You "just" have to keep Windoze out of the way (I'm on Linux, much simpler).

The problem is solved. I used Zadig WinUsb drivers and ftdi driver in openocd. The problem was in lenovo 3g modem (ericson f3507g) that conflicts with libusb. The same problems I had with st-link v2. I'v just disabled modem in device manager. That's a dirty workaround, I don't know what to do if I need 3g internet the same time.
