App note on FTDI’s FT2232 USB bridge migration, with full detailed list of capabilities on the newer FT2232H. PDF link can be found here This Application Note details the differences between the FT2232D and FT2232H to help customers design with FT2232H as this newer, high speed USB device has better performance.

JTAG debugging the ESP32 with FT2232 and OpenOCD
Erich Styger has written an article on how to use an inexpensive FTDI evaluation board as JTAG debug interface to debug ESP32 based devices: In “Eclipse JTAG Debugging the ESP32 with a SEGGER J-Link” I used a SEGGER J-Link to debug an ESP32 device with JTAG. I looked at using one of the FTDI FT2232HL […]
NEW PRODUCT: FT2232H breakout board
We have a new breakout board for the FT2232H USB2.0 high-speed IO IC. Breakouts are in stock and shipping now for $27. Read a complete overview of the design on the wiki. This board has the latest 5th generation FTDI FT2232H USB 2.0 IO chip. The FT2232 is a USB to serial converter like the […]
Preview: Bus Blaster update
A newly updated Bus Blaster design is posted in the forum. The Bus Blaster is a high-speed JTAG debugger and flash ROM programmer based on the FT2232H USB chip. Development started in the spring, but stalled because we couldn’t find the right buffer chip. We wanted to support targets from 2.0volts to 5.0volts, but we […]
Bus Pirate OpenOCD walk-through
Jrt posted some notes about using the Bus Pirate with OpenOCD: It does work – but it’s not slick or fast. If you want a cheap JTAG adapter for remote debugging or big flash writes, get an FTDI-2232 based one. But, it’ll be fine for fiddling with bootloaders or just interrogating hardware. We agree that […]
Bus Blaster: High speed USB to JTAG, SPI, UART
The Bus Pirate can program flash chips with flashrom and debug JTAG devices with OpenOCD, but it doesn’t do these things very fast. It was designed for human-speed interaction. The Bus Pirate is a good way to learn an EEPROM chip, but you eventually integrate the chip in a real circuit with actual code. In […]
