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: This command accepts bin (binary), ihex (Intel hex), elf (ELF file), s19 (Motorola s19), mem, or builder formats. All application notes are in PDF format and require a PDF reader such as Adobe Acrobat or similar before they can be viewed. It took me some time to understandhow to make OpenOCD work and flash my MCU, and I hope this tutorial will be a good and complete reference.
Note: Some time ago, the OpenOCD development team decided not to provide any official binaries anymore. They only offer the source code, expecting the vendor of the JTAG hardware to build the binaries. Ensure the binary you use supports your JTAG hardware. 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." 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. To use the FT_PROG programming tool from FTDI you might need to erase the EEPROM of the FT232H to put it into a state where FT_PROG can detect the device. To do this you can use a small eeprom command line tool from libftdi by following the steps below. Note that these steps are for Windows users (since FT PROG is only usable on Windows). libftdi is a nice open source alternative to FTDI's binary drivers. You can find more details here about interacting with the FT232H at a low level using libftdi.Asynchronous serial UART interface option with full hardware handshaking and modem interface signals. 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 The adapter can support more than one transport protocol, so OpenOCD allows you to select the transport protocol: Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design. I chose my breakout with EFM32G200F32, an ARM Cortex-M3-based microcontroller (MCU), but any other supported MCU will work.
What can the FT232H chip do? This chip from FTDIis similar to their USB to serial converter chips but addsa 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I2C, serial UART, JTAG, and more! There's even a handful of digital GPIO pins that you can read and write to do things like flash LEDs, read switches or buttons, andmore. The FT232H breakout is like adding a little swiss army knife forserial protocols to your computer! Learn how to make flashing your ARM-based MCU easy by using OpenOCD debugger with an FT2232H adapter. Here is the printout from the tutorial you suggested. Again, thank you for exploring this issue for me. 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.D4 - DTR or data terminal ready pin. Another optional pin for flow control in RS-232 serial connections. To communicate with our target chip, we need a program on the hostand hardware as a bridge between the host and the chip. In this tutorial, we will use OpenOCD as the program on the host to send commands and communicate using SWD. We'll use an FT2232H as the bridge to translate signals from the USB port to the SWD interface. Or you can build it from source code, the hard way! This is the route I chose to go, personally. You can find useful guides on how to do this,like the one from Dangerous Prototypes (for Windows), or eLinux(for Linux). You can also read compilation instructions from OpenOCD source code ( README.Windowsand README). Once the installation is done you might need to reboot your machine if the installation program tells you to do so. To make OpenOCD run, you just need a correct configuration file (.cfg) supplied to OpenOCD. This configuration file has commands which are extensions to Jim-Tcl. Jim-Tcl is a programming language that provides a simple and extensible command interpreter.
Other FTDI usb devices I have are found by ftd2xx: however, the FT232H device from Adafruit is not found, DeviceError: DEVICE_NOT_FOUND. Default debuggers embedded into evaluation boards (like STM32, EFM32, and otherMCUfamilies) by silicon vendors The OpenOCD directory file has a folder called “scripts”. In this folder, you will see "interface", "board", and "target" folders. And these are pretty much the only folders you need.Wouldn't it be cool to drive a tinyOLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduinoor Trinketto talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakoutboard! 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. First, we need to tell OpenOCD the type of adapter that it will work withby using an interface command. This error could be caused by using libusb driver in windows while new versions of OpenOCD use WinUSB driver.
