uniJTAG
The uniJTAG is a Universal JTAG programming and debugging tool for your embedded development.
The uniJTAG can be used with a broad range of microprocessors, FPGAs, Flash etc. including most of the ARM family. As long as your device supports the JTAG programming protocol it is most likely to be supported by the uniJTAG.
The board works by installing a set of Open Source drivers and afterwards installing either our JTAG programming tool or one of the supported Open Source tools. We decided to support both urJTAG and the well known OpenOCD out of the box.
OpenOCD is a very common used JTAG programming software for both Linux, Windows and MAC. The tool integrates very nicely with the free and Open Source IDE called Eclipse
So if you are looking for a very inexpensive JTAG programmer and debugger you should think about buying the uniJTAG.

Technical details
The board itself is 5 by 5 cm with a USB B connector at one side and JTAG and IO headers at another.
The JTAG port supports a wide range of voltages, as it is connected to a couple of voltage translators (74LVC2T45). This makes the uniJTAG even more universal, as you can use it together with any JTAG’able device, running at 1.2V to 5.5V.
The IO header can be used as 8 single controllable IO’s, or it can be used as a full standard UART port. With a jumper you can chose whether the IO’s should be at a 5V level, or a 3.3V level.
The board has also an onboard EEProm for storing the FT2232 configurations, so the uniJTAG is a plug and play solution, and it automatically enumerates as a JTAG and a Serial device.
