ATTENTION!!! I AM CURRENTLY UNABLE TO SHIP TO THE USA, AS THERE HAS BEEN A CHANGE IN TAXATION FOR IMPORTED PRODUCTS IN AUGUST, AND THEREFORE THE POST OFFICE IN MY COUNTRY IS NOT SHIPPING TO THE UNITED STATES DUE TO THE REORGANIZATION OF THE POSTAL SERVICE TO COMPLY WITH THE NEW US REGULATIONS. I APOLOGIZE FOR THE INCONVENIENCE.

What is it?

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.

Why did you make it?

Features:

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

What makes it special?

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

Fitted in a DP9056 (90x56 mm) standard PCB

Added series resistors to input and output pins to protect against damage and noise
