What is FT2232H?
The FT2232H is FTDI’s 5th generation of USB devices. The FT2232H is a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces. The FT2232H is available in Pb-free (RoHS compliant) 64-pin LQFP/QFN and 56-pin QVFN packages.
How do you use a JTAG connector?
To use JTAG, a host is connected to the target’s JTAG signals (TMS, TCK, TDI, TDO, etc.) through some kind of JTAG adapter, which may need to handle issues like level shifting and galvanic isolation. The adapter connects to the host using some interface such as USB, PCI, Ethernet, and so forth.
Does OpenOCD support SWD?
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.
What is Mpsse?
FTDI’s Multi-Protocol Synchronous Serial Engine (MPSSE) provides a flexible means of interfacing synchronous serial devices to a USB port. By being “Multi-Protocol”, the MPSSE allows communication with many different types of synchronous devices, the most popular being SPI, I2C and JTAG.
How do I stop OpenOCD?
Close the OpenOCD server, disconnecting all clients (GDB, telnet, other). If option error is used, OpenOCD will return a non-zero exit code to the parent process. If user types CTRL-C or kills OpenOCD, either the command shutdown or its replacement will be automatically executed before OpenOCD exits.
How do I use OpenOCD on Windows?
To run OpenOCD, navigate to openocd-0.5. 0/tcl in the command console and run OpenOCD as above. You can also create a new folder anywhere on your system, and copy openocd.exe and the contents of openocd-0.5. 0/tcl to the new folder.
What is the ft2232hl?
The FT2232HL is dual high-speed USB to UART/FIFO device, and similar FTDI devices are used on many boards as UART to USB converters. With OpenOCD these devices can be turned into inexpensive JTAG debug probes.
How do I use the usb-2-serial port on the FT2232 board?
The FT2232 board has two USB-2-Serial ports. While using one for JTAG debugging, the second one can be still used as an extra serial port which is a cool extra feature. For this, connect pin 0 and 1 of the CDBUS plus GND:
Where does the ft2232h MINI module connect to the CN?
In most cases, the FT2232H pin is connected directly to the associated pin on CN2 or CN3. The FT2232H Mini Module allows configuration with both USB Bus-powered and USB Self-powered designs:
How do I connect my FT2232 to my OpenOCD device?
The FT2232 shows up with two USB serial ports in the Windows device manager: FT2232HL in the device manager For OpenOCD, use the SysProgs USB Driver Tool on Windows to load the WinUSB Driver for the FT2232HL chip. Notice that it shows up here as ‘USB Serial Converter A’ and ‘USB Serial Converter B’.
