bdiGDB for GNU Debugger, BDI2000 (ARM11/Cortex-A8) User Manual 4

1 Introduction

bdiGDB enhances the GNU debugger (GDB), with JTAG debugging for ARM11 and Cortex-A8 based targets. With the builtin Ethernet interface you get a very fast download speed of up to 200 Kbytes/ sec. No target communication channel (e.g. serial line) is wasted for debugging purposes. Even bet- ter, you can use fast Ethernet debugging with target systems without network capability. The host to BDI communication uses the standard GDB remote protocol.

An additional Telnet interface is available for special debug tasks (e.g. force a hardware reset, program flash memory).

The following figure shows how the BDI2000 interface is connected between the host and the target:

1.1 BDI2000

The BDI2000 is the main part of the bdiGDB system. This small box implements the interface be- tween the JTAG pins of the target CPU and a 10Base-T ethernet connector. The firmware and the programable logic of the BDI2000 can be updated by the user with a simple Windows / Linux config- uration program. The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target systems with Rev. A/B).
