Even with this mod, my Olimex is still acting strangely under the recent
OCD Commander.  Anything other than speed 8 gives me the dreaded:
"Error Response from INITIALIZE: 0x03 initialize_target : cable
disconnected  (10 : 03)".

Speed 8 appears to work, but it is horribly slow.  Some of the older
versions seem to work better, in that I can do the initial connect at speed
8, then switch to speed 2 or 3.  But even then, I'm seeing a lot of unknown
opcodes during single stepping, and stepping through a BL doesn't show the
link register updating.

I think I'll try your circuit next.  This Olimex jtag
'almost-a-wiggler-clone' cable is terribly frustrating.
