The ICprog OpenOCD is a USB JTAG adapter for OpenOCD. It drives every ARM board from In-Circuit and carries a TTL UART on a second pin header alongside the JTAG connector — programming and listening on one cable.

Drivers on Windows

On Windows the matching libusb-1.0 (WinUSB) drivers are needed:

1. Go to zadig.akeo.ie and download the current Zadig release.
2. Plug in the adapter.
3. Run zadig.exe — confirm the User Account Control prompt.
4. If the device is not in the list, enable Options › List All Devices.
5. Select Dual RS232 in the list.
6. Choose the WinUSB driver in the right-hand selector.
7. Click Install Driver or Replace Driver and confirm.

The adapter reports two interfaces (interface 0 and interface 1); the driver must be set for both. If one is left without a driver, OpenOCD detects the device but cannot address the JTAG interface.
