No, there is no connection at all on my COM1 port

I have a Edgeport USB to 4x serial converter on a USB port connected for
getting terminal output from the board. May this cause the trouble ?

Did not get more logging information (as before):

(gdb) target remote | m68k-elf-sprite -v pe://ParallelPortCable m5235evb
Remote debugging using | m68k-elf-spm68k-elf-sprite:CodeSourcery
ColdFire Debug
Sprite (Sourcery G++ Lite 4.2-8)
rite -v pe://ParallelPortCable m5235evb
Ignoring packet error, continuing...
warning: unrecognized item "timeout" in "qSupported" response
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Ignoring packet error, continuing...

Get additionally a windows dialog box from application
m68k-elf-sprite.exe:

"The instruction at "0x004037c5" referenced memory at "0x00000000", the
memory could not be "read".
