So far, H-JTAG does not work with ARM SDT2.51 either, so it's problem
is not JUST with Keil. Using an Olimex LPC2148 board and an Olimex
Wiggler clone, the H-JTAG server reports "Unable to find target", so
in this case, it can not work with ANY debugger. Earlier in this
thread Tsvetan said "the H-JTAG as is will not work with our ARM-JTAG
as it doesn't handle the JTAG-ENABLE pin we have on our JTAG".  If
that is the ONLY problem with H-JTAG it should be simple fix to get it
going with the Olimex hardware??

FWIW, the H-JTAG.sys driver that provides direct port access under
Windows seems to be working fine.  It is a derivative of Dale Robert's
GiveIO.sys driver, so I tested it with Dale Robert's TestIO code, and
it played the test tune on the PC speaker correctly.
