OpenOCD is a software project started by Dominic Rath several years ago. It is now a open source project and can be downloaded from here. It now connects to several target machines through many debug/programming interfaces. A list of supported targets can be found in chapter 6 of the documentation (although the documentation list lags behind the targets that are supported). Below are programming/debugging interfaces that mention OS X compatibility. View the OpenOCD Google+ pages here.

Instructions here:

Install instructions are here:

gdb is the debugger that is typically used under OSX for embedded debugging if the semiconductor supplier doesn’t offer a OS X solution for their part. A little background on gdb is here.


If you are new to building your own tools, you might want to look at my Command Line Tips page.

Bus Pirate

The Bus Pirate is accessed from a command line in a OS X terminal. When powered up all I/O lines are high impedance. From there, a bus mode can be selected to use the Bus Pirate with a specific protocol. Bus modes : 1-Wire, UART, I2C, SPI, raw 2-wire, raw 3-wire, HD44780 LCDs, MIDI, PC keyboard, DIO, JTAG.

USB to Chip Adapters compatible with OpenOCD

All FTDI Based Adapters

Many evaluation boards use a FTDI chip for USB to JTAG communications. FTDI makes two kinds of drivers, the VCP version for serial port emulation, and the D2XX version which are more general and designed for dynamic libraries. To use the JTAG features you need the D2XX version. There are compatibility issues between the two, see the FTDI read me here.

Download the D2XX version: http://www.ftdichip.com/Drivers/D2XX.htm
