Bus Blaster v4 design overview

From DP

Bus Blaster v4 is an experimental, high-speed JTAG debugger for ARM processors, FPGAs, CPLDs,

flash, and more. Thanks to a reprogrammable buffer, a simple USB update makes Bus Blaster v4

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

◾ Reprogrammable buffer is compatible with multiple debugger types

◾ Compatible with 'jtagkey', 'KT-link' programmer settings in OpenOCD

(http://openocd.berlios.de/web/) , urJTAG (http://urjtag.sourceforge.net/) , and more

◾ Should support Serial Wire Debug when available

◾ Mini-CPLD development board: self programmable, extra CPLD pins to header
