Connecting the Abatron BDI2000 JTAG Debugger to your host
The Abatron BDI2000 JTAG Debugger enhances the GNU debugger with JTAG debugging for
The following illustration shows how the Abatron BDI2000 JTAG Debugger is connected
to your host:
Architecture for connecting the Abatron BDI Debugger to your host machine.
The BDI2000 box implements the interface between the JTAG pins of the target CPU and
the Ethernet connector. Later, you'll install the specific Abatron firmware, and
configure the programmable logic of the BDI2000 Debugger device.
To physically connect the Abatron BDI2000 Debugger to your host machine:
Connect one end of an Ethernet cable into the RJ45 jack of the Abatron BDI2000
Debugger, and the other end into a network switch connected to your LAN.
Connect the female end of a serial cable to the serial port of the Abatron
BDI2000 Debugger device, and then connect the other end to a COM port on the
Note: Don't connect a JTAG debug cable into the Abatron BDI2000 Debugger.
The debugger shouldn't be connected to the target until after you've
updated the Abatron firmware for that architecture.
Connect the power adapter to the Abatron BDI2000 device, and then plug it in.
At this point, the BDI2000 module should visibly power on.
Note: The flash memory of the Abatron BDI2000 JTAG Debugger stores the IP address of the
debugger as well as the IP address of the host, along with the configuration file
and the name of the configuration file. Every time you turn on the Abatron BDI2000
JTAG Debugger, it reads the configuration file using TFTP (TFTP is included with the
