The adapter can support more than one transport protocol, so OpenOCD allows you to select the transport protocol: All of the suggested tutorial works as one would expect, see below. This is actually where I started. However, when trying to use the FT232H with other programs that specify the drivers from FTDI, i.e., FTD2XX drivers, those programs can not find the FT232H device Information. A standard call for .getDeviceInfo() fails. I believe it is because this (������) is what is read instead of the actual device information. Therefore an error is thrown:

Operation configuration mode and USB Description strings configurable in external EEPROM over the USB interface. FT2232H is dual high-speed USB to multipurpose UART/FIFO IC. This means it is a single-chip USB with dual ports.

In conclusion, if you don’t have much budget, time, or patience, OpenOCD with FT2232H will be a great choice for you. Requirements USB High Speed Power Delivery Series are now available here. With added Power Delivery(PD) functionality to the existing High Speed Series.

Connect TDI to SWDIO via a suitable series resistor (220-470 Ohm or so depending on the drive capability of the target and adapter) connect TDO directly to SWDIO.”

FT232H – Hi-Speed Single Channel USB UART/FIFO IC

Once the installation is done you might need to reboot your machine if the installation program tells you to do so. Other FTDI usb devices I have are found by ftd2xx: however, the FT232H device from Adafruit is not found, DeviceError: DEVICE_NOT_FOUND. Every port is equipped with an engine called aMulti-Protocol Synchronous Serial Engine (MPSSE) to simplify asynchronous serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design. This allows users to configure the channel with the desired protocol. MPSSEs are available on channel A and channel B and can be configured to allow any synchronous serial protocol. Be Aware Before Selecting OpenOCD I chose my breakout with EFM32G200F32, an ARM Cortex-M3-based microcontroller (MCU), but any other supported MCU will work.

Note:Defining the SWD_EN signal is important for makingOpenOCD work, even though we didn’t connect it physically. If we don't, an error will appear: First, we need to tell OpenOCD the type of adapter that it will work withby using an interface command.Inside device manager look under the Ports (COM & LPT) node and you should see a USB Serial Port (COMx) device, where x is a number like 5. This COMx is the COM port assigned to the FT232H serial UART, and what you should use when connecting to the serial port in the Arduino IDE or with a serial terminal program.
