1 Introduction
bdiGDB enhances the GNU debugger (GDB), with COP debugging for PowerPC 6xx/7xx/82xx/83xx
based targets. With the built-in Ethernet interface you get a very fast code download speed. No target
communication channel (e.g. serial line) is wasted for debugging purposes. Even better, 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 between the JTAG pins of the target CPU and a 10Base-T Ethernet connector. The firmware and the
programmable logic of the BDI2000 can be updated by the user with a simple Windows based configuration program. The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target systems with Rev. B).
Note for 1.8V / 2.5V I/O voltage:
Some PowerPC designs work with 1.8V or 2.5V I/O voltage. This is not supported by the BDI2000
Rev. B. You need level shifters when using the BDI2000 Rev. B together with such a system.
