Using Bus Blaster + openOCD on OSX Mavericks
Alvaro wrote an article on using a Bus Blaster + openOCD on OSX Mavericks: I’ve been using the Dangerous Prototypes Bus Blaster along with openOCD to program/debug my LPC1769 microcontroller. It’s been a while since I did anything, so when I tried again last week and couldn’t get it to work, I was slightly confused. The […]

PROTOTYPE: Ethernet JTAG debugger for OpenOCD
We’re releasing a stalled or abandoned prototype every few days while Seeed Studio is on break. We put a lot of work into these projects, but they’re still missing major components and testing. If an abandoned project sparks your interest, we may have PCBs to get you started. The goal of this project was to […]
Debugging the Bus Blaster
Bus Blaster is getting really close.
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 […]
Bus Pirate OpenOCD JTAG how-to
Michal Demin posted a tutorial for the OpenOCD JTAG debugging support he added to the Bus Pirate. Some time ago, I have added support to OpenOCD to be able to use Buspirate as JTAG interface. This how-to will show you, how to setup all the things necessary. Things you will need: – Buspirate – Computer […]
Bus Pirate OpenOCD support update
robots, a new contributor to the Bus Pirate OpenOCD support effort, has taken charge and produced the first working toolchain. A patch for OpenOCD 0.3.0 that adds Bus Pirate support is here. The latest compatible OpenOCD firmware for the Bus Pirate is here, bootloader v4 required. JTAG programming speed is a paltry 1.4kb/s, about a […]
Bus Pirate: OpenOCD (JTAG) firmware port v00
A Bus Pirate v2go/v3 port of the OpenOCD JTAG debugger source code from USBPROG is complete. You can download the source and latest compile from the OpenOCD folder in the project SVN. Firmware is only half of the equation though, OpenOCD doesn’t yet support the USBPROG protocol over a (virtual) serial port like the Bus […]
Bus Pirate OpenOCD (JTAG) support update
OpenOCD is a popular open source JTAG utility. Zach Welch, a regular contributor to the project, has offered to help add Bus Pirate support.You can follow the progress in his git repository. The current plan is to port the excellent work done by the USBPROG project to the Bus Pirate. Here are some tentative goals: […]
