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 
Our JTAG have the folowing pin assignments:

DB25.2 -> INVERSE -> JTAG.15 (NTRST) 
DB25.3 -> JTAG.7 (TMS) 
DB25.4 -> JTAG.9 (TCK) 
DB25.5 -> JTAG.5 (TDI) 
DB26.6 -> JTAG.3 (TRST) 
DB26.9 -> VCC for the Level shifter i.e. JTAG enable/disable 
DB25.11 <- JTAG.13 (TDO) 
DB25.13 <- Target VCC sense (only when JTAG is enabled i.e. DB26.9 = 1) 

H-JTAG doesn't set DB26.9 = 1 i.e. doesn't enable the ARM-JTAG, this 
can be easily fixed as the source is available.
One of our engineer works on it and I e-mailed twentyone about this.

Best regards
