Problem with P&E ParallelPortCable - Sourcery g++ Lite 4.2-8

[Christof Frey]

I am working with the P&E parallel cable and have installed the supplied
drivers from CodeSourcery.
Unable to debug.
Getting the following:
 
C:\Projects\helloworld_mcf523x\src>m68k-elf-sprite -i
CodeSourcery ColdFire Debug Sprite (Sourcery G++ Lite 4.2-8)
pe: [speed=<n:0-31>&memory-timeout=<n:0-99>] P&E Adaptor
  pe://CycloneProMaxSerial:1 - COM1 : Serial Port 1
  pe://ParallelPortCable:1 - LPT1 : Parallel Port 1 (Address $0378)
ccs: [timeout=<n>&speed=<n>] CCS Adaptor
  ccs://$Host:$Port/$Chain_position - CCS address
 
When I try to debug:
 
C:\Projects\helloworld_mcf523x\src>m68k-elf-gdb hello.elf

(gdb)
 
(gdb) target remote | m68k-elf-sprite pe: m5235evb

m68k-elf-sprite:Opening P&E CycloneProMaxSerial port 1 (COM1 : Serial
Port 1)
Ignoring packet error, continuing...
warning: unrecognized item "timeout" in "qSupported" response
Ignoring packet error, continuing...
 
Why is the sprite trying to open the P&E CycloneProMaxSerial port 1 ?
(instead of the known ParallelPort on address $0378)
Additionally I get a dialog box indicating that there is a driver update
for the CycloneProMaxSerial  going on (and finally fails)!!
 
so, trying to configure the correct adapter with the whole descriptor
instead of just pe:
 
(gdb) target remote | m68k-elf-sprite pe://ParallelPortCable m5235evb
Remote debugging using | m68k-elf-sprite 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...
 
here things are getting even more wired. I get a dialog box saying "The
instruction at "0x004037c5" referenced memory at "0x00000000". The
memory could not be "read"."
Looks like a null pointer access in the driver.
 
Any ideas / suggestions welcome
 
Christof
