The electrical connections are identical to the Bus Blaster v2. Get a Bus Blaster v2 for $34.95. In version 3 we moved the Bus Blaster […]
Bus Blaster with FTjrev
jrev automates the reverse engineering of JTAG connections. The Bus Blaster v2+ with the PicoTap buffer installed works with the FTjrev version for FTDI chips. Via the forum. You can get a Bus Blaster v2 for $34.95.
Bus Blaster v2 back in stock
Bus Blaster v2 JTAG debugger is back in stock at Seeed Studio.The cool thing about the Bus Blaster is that it uses a programmable logic chip as a buffer. It can imitate different types of programming hardware with a simple USB update. You can get a Bus Blaster v2 for $34.95.
Test buffer logic for Bus Blaster v3
A test buffer for the CPLD on the experimental Bus Blaster v3 is now available in the forum. The self test passed, but it needs more real-world testing. If you built a Bus Blaster v3 free PCB please give it a try and report how it went. Bus Blaster v3 is a small update to […]

Bus Blaster v4 free PCB build
Skot built a free Bus Blaster v3 v4 PCB, a high-speed JTAG debugger for ARM processors, FPGAs, CPLDs, flash, and more. v3 v4 is a small update to v2/v2.5 with symmetrical connector placement to make it fit a case. If you build a free PCB we’ll send you another one! Blog about it, post a […]
Using Bus Blaster v2 to debug STM32s from CooCox
Arhi needed to do some debugging on an ET-STM32F103 board. He whipped out his Bus Blaster v2 and got it working with the CooCox IDE, a free tool for working with ARM Cortex M0 and M3 32bit microcontrollers. To summarize, if you want to program Cortex M0 or Cortex M3 on windows CooCox works perfectly […]
Workshop video #04: Bus Blaster v4 solder and assembly
Today is the second half of the Bus Blaster v4 workshop video. We solder the board, including two big TQFP chips and a bunch of 0603 passives. The Bus Blaster is our inexpensive, open source JTAG debugger based on the FTDI FT2232H USB->serial chip. Bus Blaster v4 adds a support for a new type of […]
Workshop video #03: Bus Blaster JTAG debugger history
In this video Texas Instruments gets the Big Box award, and we discuss the evolution of the Bus Blaster JTAG debugger. The Bus Blaster is our inexpensive, open source JTAG debugger based on the FTDI FT2232H UBS->serial chip. This chip has 2 JTAG interfaces and can program/debug two separate JTAG targets. Bus Blaster v1 used […]
Bus Blaster: Programming the STM32F4 DISCOVERY
Nabil programed the STM32F4 DISCOVERY development board using the Bus Blaster JTAG debugger and open source OpenOCD software: My initial research lead me to texane’s github where he created a linux version of ST-LINK. It doesn’t support the STM32F4 yet, but there is a fork which is making good progress. I couldn’t get either to […]
Programming the STM32F4 DISCOVERY with the Bus Blaster
Nabil wrote to say, “I’ve had success programming and debugging using the Bus Blaster. In this post I will show you how to program and debug the Discovery board using open source hardware and software.” Via the contact form.
Bus Blaster hack: Flashing a PC BIOS chip
Zougloub modified the Bus Blaster V2 somewhat and successfully flashed a PC BIOS chip. By using the onboard FTDI FT2232H chip in SPI mode, and slightly modifying the CPLD logic, he successfully established a link to the BIOS chip. He was now able to update his BIOS and use a processor with his motherboard that […]

Bus Blaster v2 JTAG debugger is back in stock at Seeed Studio.The cool thing about the Bus Blaster is that it uses a programmable logic chip as a buffer. It can imitate different types of programming hardware with a simple USB update. This batch is a new revision (v2.5). It includes a button and LED […]
Forked Bus Blaster FT2232H + CPLD JTAG programmer
irrenhaus finished his forked Bus Blaster v2 design. Like the BBv2, this board has a FT2232 USB->JTAG chip and a CPLD buffer. It uses a bigger 100pin CPLD, with enough IO to connect to every pin of the FT2232. The extra connections are used to supports the SWO feature of the new 2-wire SWD JTAG […]

Bus Blaster: goJTAG via new PicoTAP-compatible buffer
Bus Blaster v2 now supports goJTAG via a new PicoTAP-compatable buffer. goJTAG is an open source GUI for experimenting with JTAG devices: goJTAG software allows users to study boundary-scan techniques, to carry out their own experiments, to perform diagnosis, and much more. The software environment comes with a built-in example project, and users can create […]
Bus Blaster release package v2.0
Over the last few weeks we did a massive cleanup and reorganization of our SVN code repository. Most projects now follow a standard directory structure. All our in-progress and stalled project files are now completely open and available to anyone. We also included all the manufacturing resources used to initiate production at Seeed, and the […]
