Hello Steve,

Maybe the following can help you.
I installed the Coldfire GNU toolchain on a machine that run under Windows XP professionnal SP2. 
I'm using Linux, but here goes...
I can connect to a M52235EVB using P&E USB Coldfire Multilink using the following operations: 

1) From the command line, execute GDB:
    m68k-elf-gdb <elf_file>

$  m68k-elf-gdb
GNU gdb (CodeSourcery Sourcery G++ 4.1-30) 6.5.50.20061105-cvs

This GDB was configured as "--host=i686-pc-linux-gnu --target=m68k-elf".

(gdb)

So far, so good.

2) From GDB, type:
    target remote | m68k-elf-sprite pe://USBMultilink m52235evb

(gdb)  target remote | m68k-elf-sprite pe://USBMultilink m52235evb
Remote debugging using | m68k-elf-sprite pe://USBMultilink m52235evb
m68k-elf-sprite:error:Cannot load P&E DLL
Remote communication error: Connection reset by peer.
(gdb)

Linux doesn't use DLL's, does it?

3) From GDB, type:
    load


Remark:
GDB seems to have a lot of difficulty when executing the "load" command. Most of the time the command will fail. It seem that waiting some time before doing a "load" command can help. Maybe there are some parameters that can be set in "sprite" that can resolve this issue. 

Claude.
