![]() I've tested ARM-USB-OCD-H with the WinUSB drivers and this release of OpenOCD compiled by Freddie Chopin: – you can test the setup directly via OpenOCD initially as described in ARM-USB-OCD-H's user's manual. Try with these versions:įinally, make sure that you use the configuration file "olimex-arm-usb-ocd-h.cfg" for ARM-USB-OCD-H found in FTDI subfolder (".openocd-0.9.0\scripts\interface\ftdi"). It would depend where you got OpenOCD from. run installers from NVIDIA Driver Downloads). The recommended way to install drivers is to use the package manager for your distribution but other installer mechanisms are also available (e.g. Yes, WinUSB drivers are recommended now but you can also compile OpenOCD with the option to work with the older LibUSB drivers. Before you get started, make sure you have installed the NVIDIA driver for your Linux distribution. Note that OpenOCD can be compiled with different driver support. Make sure that both these interfaces have WinUSB driver installed (there is an option in Zadig to show all devices, make sure that both interfaces of ARM-USB-OCD-H have the same driver). It is possible that you installed the driver only for the COM port, leaving the JTAG interface without a driver. However, note that ARM-USB-OCD-H has two serial interfaces –> one interface for the COM port near the USB connector, and another one for the JTAG interface. It seems that you installed the WinUSB driver for OpenOCD. This seems like driver mismatch or error. ![]()
