On-chip Debugging
The increasing complexity of today's
software and hardware designs is
leading to some fresh approaches to
debugging Silicon manufacturers
offer more and more on-chip debug-
ging features for emulation of new
processors.
This capability, implemented in
various processors under such
names as Background Debug Mode
(BDM), JTAG and on-chip emula-
tion, puts basic debugging functions
on the chip itself. With BDM or
JTAG debug port, you control and
monitor the microcontroller
solely through the stable on-chip
debugging services. This debugging
mode runs even when the target
system crashes and enables devel-
opers to continue investigating the
cause of the crash. You won't waste
time and target resources with a
software ROM monitor, and you
eliminate the cabling problems
typical of ICEs.
Capitalizing on this technology,
Abatron offers the high-speed
BDI2000 BDM/JTAG interface with a
comprehensive support for debug-
gers from leading vendors.
BDI2000 allows communication via
RS232 or 10 BASE-T Ethernet
between the development computer
and the BDM/JTAG interface of the
target system.
Excellent Performance
The BDI2000 communicates with the
target system with up to 16 Mbit/s and
allows very fast program download rates
of up to 320 Kbytes/s.
In most cases, the BDI2000 and the
associated software packages eliminate
the need for expensive hardware such as
an in-circuit emulator. Even better, the
BDI2000 accesses the on-chip emulation
capabilities of today's newest processors
which aren't supported by traditional
ICEs.
Advanced Hardware Technology
As a result of consistent implementation
of latest technology, the BDI2000 is
optimally prepared for further
enhancements.
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 target systems from 1.8 Volts
to 5.0 Volts.
Typical Application
The following example shows BDM/JTAG
debugging via 10 BASE-T Ethernet
connection.
