Default debuggers embedded into evaluation boards (like STM32, EFM32, and otherMCUfamilies) by silicon vendors After rebooting, plug in the FT232H breakot to your PC using a USB micro cable. You should see a message pop up that the device is recognized and a driver is being installed. 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. To flash an image to internal flash, we need to define internal flash banks. It could be one bank like our present target, “efm32.cfg” did for us. To make sure, type the following: Also, I advise anyone searching for debugging tools to choose wisely. For example, if you need a simple tool, I think OpenOCDmight not be the best choice for you!

BTW: When I am asked to specify the USB device as in the printout above, what should I try? I have already tried the serial number FTLD454D, the productID 0x6014, and the vendorID 0x403.Bitbang mode: toggling an I/O pin ‘bitbashing’ which FTDI call ‘bitbanging’, refers to driving the I/O pins directly, rather than using an I/O protocol embedded in the device." The table below lists all the currently available application notes and indicates which devices the documents are relevant to. Upgrading a passive DB9 RS232 Interface to an active USB Interface using an FTDI DB9-USB-RS232 Module Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.

openocd -f config1.cfg -f config2.cfg -f config3.cfg Understanding the Basics of Adapter Configuration You must also tell OpenOCD more information about your adapter (interface). For example, you need to specify the VID/PID, serial number, or the number of the channel you will use for FT2232H, since it has two channels. In our tutorial, we will use an adapter with FT2232H chip, so we will use an FTDI interface driver: D5 - DSR or data set ready pin. Like DTR, this is another optional pin for flow control in RS-232 serial connections. FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.

D0 - TX or transmit pin. This pin is the serial data output by the FT232H chip and should be connected to the RX or receive pin of a serial device. In addition to being free and open source, OpenOCD also has a good support community. BUT, as with any other open-source tool, you could face bugs you may need to fix by yourself. First connect your FT232H board to the machine and follow the Zadig tool steps here to enable the libusb-based driver for the FT232H board.

The FT232H I have seems to be unable to supply its information when using FTD2XX drivers, hence my original post to understand how I might correct this.
