Hi again Dave,
    H-JTAG is now working with ARM SDT2.51 debugger!! 
Congratulations for twentyone.
You need to disable semihosting and vector catching.
Click on View->Debugger internals
On semihosting enable put 0x00000000
On vector_catching change the string 
%RUsPDAifE to %ruspdaife

     I am using a very simple home made wiggler.
See schematic on files area.

1. Put a jumper from pin 8 to pin 15 of DB25 connector.
2. Use 74HC244 chip.
     Good luck and happy new year.
