Thanks to a reprogrammable buffer a simple update over USB makes Bus Blaster compatible

with many different JTAG debugger types in the most popular open source software.

• Based on FT2232H with high-speed USB 2.0
• Buffered interface works with 3.3volt to 1.8volt targets
• Reprogrammable buffer is compatible with multiple debugger types
• Compatible with 'jtagkey' 'KT-link' programmer settings in OpenOCD
• urJTAG and more
• ships with JTAGkey compatible buffer image pre-programmed
• Should support Serial Wire Debug when available
• Mini-CPLD development board: self programmable extra CPLD pins to header
• Open source (CC-BY-SA)

Updates in v4:

• V4 uses a larger CPLD than previous versions. It can now support the SWV feature of Cortex microcontroller for advance debugging when software support is available
• SWV is little used and not currently supported in software most users will be better off with Bus Blaster v3 available here
• Fitted in a DP9056 (90x56 mm) standard PCB
• Added series resistors to input and output pins to protect against damage and noise

Each unit is tested before it ships.
