1 Introduction
bdiGDB enhances the GNU debugger (GDB), with Background Debug Mode (BDM) debugging for
MPC8xx/MPC5xx 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 BDI3000 interface is connected between the host and the target:

1.1 BDI3000
The BDI3000 is the main part of the bdiGDB system. This small box implements the interface between the JTAG pins of the target CPU and a 10/100Base-T Ethernet connector. The firmware of the
BDI3000 can be updated by the user with a simple Linux/Windows configuration program or interactively via Telnet/TFTP. The BDI3000 supports 1.2 – 5.0 Volts target systems.
