Ethernet JTAG debugger
From DP
Contents |
Overview
- The goal of this project was to make a high-speed Ethernet and USB connected JTAG debugger for OpenOCD. It uses a PIC24FJ256GB106 with USB, and an ENC424J600 100MBPS Ethernet chip.
This project is currently stalled. We grew tired of messing with Microchips gratis-but-not-libre TCPIP stack, and lost interest in developing a new project with it.
