This does not mean anything. I haven't seen a single case  where  the
network  speed  was  the limiting factor. Shuffeling the data through
the JTAG is usually much slower.

What would you want to extend or scale?

In other words: The  BDI2000  fits  seamlessly  into  a  Linux  based
development  environment.  You  can  use exact the same tools and and
user interface for low level stuff (boot loader,  OS  and  drivers  -
using the BDI) and for application code (using gdbserver).

Question: does the Lauterbach reliably handle issues like  relocating
the symbol table as needed für U-Boot?

Another pro for the BDI: they have  *excellent*  support.  I  know  a
couple  of vendors of hardware and tools etc. Some of them are really
good, but Abatron beats them all.
