bdiGDB for BDI2000 (PowerPC 7440/7450/86xx) User Manual 3

1 Introduction
bdiGDB enhances the GNU debugger (GDB), with JTAG/COP debugging for PowerPC 7440/7450/
86xx 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 be-
tween 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 con-
figuration program. The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target sys-
tems with Rev. B).
