This is absolutely correct except for the word "only".
The BDM4GDB project at sourceforge (see bdm4gdb.sourceforge.net)
provides all necessary information to build a home-made parallel port
adapter (schematics, source extension to GDB) which allows to do the
same. If you cannot build a simple PCB yourself, we offer BDM4GDB
adapters at production cost ($ 50, including a CD-ROM with sources
and binary for the modified GDB) as a service to the Linux community.
The main differences between the BDI2000 and BDM4GDB:
* BDI2000 connects to the Ethernet, BDM4GDB needs a parallel port on
* BDI2000 has support for many CPU types, BDM4GDB restricted to
MPC8xx (so far)
* BDI2000 has support for all comon flash types, BDM4GDB needs some
more work in that area (but you can adapt it yourself when needed -
it's Open Source)
* BDI2000 is much faster for code download / flash programming
* The BDI2000 costs around $ 2,500, BDM4GDB $ 50.
I will give a presentation "Debugging of Linux Kernel and Device
Drivers Using Low-Cost BDM Interface" featuring the BDM4GDB on May 4
