JTAG debugging the ESP32 with FT2232 and OpenOCD

Erich Styger has written an article on how to use an inexpensive FTDI evaluation board as JTAG debug interface to debug ESP32 based devices: In “Eclipse JTAG Debugging the ESP32 with a SEGGER J-Link” I used a SEGGER J-Link to debug an ESP32 device with JTAG. I looked at using one of the FTDI FT2232HL […]

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 […]

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 […]
