An experimental, high-speed JTAG debugger Compatible with many different JTAG debugger types ships with JTAGkey compatible buffer image pre-programmed Support Serial Wire Debug when available Open Source

Bus Blaster v4 is an experimental, high-speed JTAG debugger from Dangerous Prototypes.

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)

    • Bus Blaster Manual

    • Bus Blaster design overview

    • Bus Blaster forum

    • CPLD buffer logic overview

    • 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

    • ŸSWV 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

Updates in v4:

Each unit is tested before it ships.
