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 … Read more
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 … Read more
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 … Read more
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, … Read more
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 … Read more
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 … Read more
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, … Read more
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.
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 … Read more

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 … Read more
Bus Blaster v2 is back in stock at Seeed Studio. You can get a Bus Blaster v2 for $34.95.
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 … Read more
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. … Read more

Bus Blaster v2 is a pain to test at the factory. That is likely holding up the supply. A simple Windows test application would help things along. It’s a very basic app if you’re already setup to work with FTDI … Read more
Piotr built a free Bus Blaster v2.1 PCB. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer. … Read more
Tanukifu successfully built a free Bus Blaster v2.1 PCB. It was uneventful build, except for a few bridges on the PCB. Be sure to inspect the Bus Blaster board if you’re building a free PCB. There have been a lot … Read more
rubi posted a picture of a fully constructed Bus Blaster v2 free PCB. If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code … Read more
A couple more Bus Blaster v2 JTAG debugger boards are in stock at Seeed Studio. This is probably the tail end of the first batch. More are on the way, probably in a few weeks. Something that would help significantly … Read more
