Bounty for a Bus Blaster v2 self-test app
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 chips, but we’re not. To speed things along, we’re offering a bounty for a test […]
Bus Blaster v2.1 free PCB build
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. You can get a Bus Blaster v2 for $34.95.
Bus Blaster v2.1 (v2.6) free PCB build
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 of bridge issues, we probably messed up the fill or gerber settings. v2.1 is actually […]
Bus Blaster v2 free PCB build
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 for the free PCB drawer. You can get a Bus Blaster v2 for $34.95. (Well, […]
Bus Blaster v2 back in stock
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 is a self-test program for the Bus Blaster v2. We’ll integrate a test mode into […]
Bus Blaster v2 back in stock
A few reserve Bus Blaster v2 JTAG boards are in stock at Seeed Studio. A new batch is on the way too. Get one for $34.95
Lib(X)SVF: A library for implementing SVF and XSVF JTAG players
libxsvf is an open source library for ‘playing’ SVF and XSVF JTAG programming files. It supports a number of programmers, including the Bus Blaster v1 and v2.
NEW PROTOTYPE: Bus Blaster v2
It’s finally here! The Bus Blaster v2 JTAG debugger is now in stock and shipping at Seeed Studio. Read the full hardware design article There’s a ton of JTAG debuggers out there, what makes the Bus Blaster v2 so special? V2 has a reprogrammable logic chip (CPLD) that sits between the FT2232H USB chip and […]
Bus Blaster v2: JTAG Serial Wire Debug support
A KT-link buffer clone supporting JTAG Serial Wire Debug is now available for Bus Blaster v2 pre-release testers. This should support the new 2-wire SWD debugging protocol when available in OpenOCD and urJTAG. The KT-link is the first FT2232-based JTAG debugger with support for the new SWD and SWV JTAG interface used on low pin […]
LibSWD: JTAG serial wire debug library
libswd is an open source library for the new 2-wire JTAG protocol called Serial Wire Debug. The developer is currently working to integrate it with OpenOCD and urJTAG. Most open source projects supporting SWD seem to be standardizing on the KT-link style FT2232 programmer. The CPLD on Bus Blaster v2 can imitate the KT-link buffer, […]
PROTOTYPE: Bus Blaster v1 JTAG debugger
The Bus Blaster is a high-speed JTAG debugger/programmer that works with many ARM processors, CPLDs, FPGAs, and flash chips. It’s compatible with the most popular open source JTAG utilities such as OpenOCD and urJTAG. After almost a year of on-and-off development the first Bus Blaster v1 prototype is available. This initial batch is offered to […]
Bus Blaster v2 inspired JTAG debugger
irrenhaus posted a JTAG debugger design inspired by the Bus Blaster v2: I was developing my own version of a JTAG programmer with the FT2232H as I saw this project here. I liked the Idea with the CPLD very much and I’d love to play with CPLD’s or FPGA’s so I decided to adopt this […]
Bus Blaster v2 testing
We’ve just completed verification of the Bus Blaster v2 JTAG debugger. V2 is much more flexible than v1, and uses a programmable logic chip (CPLD) for the buffer. The logic chips in v1 were expensive to source and place, but v2 uses a $1 CPLD with a bunch less pins to solder and inspect. Bus […]
Bus Blaster v2 development
We got a big box of PCBs from Seeed this week. This is an update of the Bus Blaster (in test production now) with a CPLD instead of discrete logic buffer chips. The CPLD is connected to the secondary JTAG B port of the ft2232. This should make it like a mini CPLD development board, […]
Debugging the Bus Blaster
Bus Blaster is getting really close.
Bus Blaster power up test
Soldering and power up test for the Bus Blaster board complete. The FT2232H enumerated properly as a USB device with two virtual serial ports.
mini-Blaster and Bus Blaster boards
A big box of boards came today. Here’s the PCBs for the FT232 inexpensive programmer and the Bus Blaster JTAG programmer. The first draft of these boards are white.
Preview: Bus Blaster update
A newly updated Bus Blaster design is posted in the forum. The Bus Blaster is a high-speed JTAG debugger and flash ROM programmer based on the FT2232H USB chip. Development started in the spring, but stalled because we couldn’t find the right buffer chip. We wanted to support targets from 2.0volts to 5.0volts, but we […]
Bus Blaster: High speed USB to JTAG, SPI, UART
The Bus Pirate can program flash chips with flashrom and debug JTAG devices with OpenOCD, but it doesn’t do these things very fast. It was designed for human-speed interaction. The Bus Pirate is a good way to learn an EEPROM chip, but you eventually integrate the chip in a real circuit with actual code. In […]
