To adapt from standard 20pin header you need an adapter. As example the [http://www.lauterbach.com/frames.html?ord__7748.html Lauterbach] one:

Texas Instruments uses (e.g. on BeagleBoard) a variation on the standard ARM 2x7 JTAG header:

ARM PIN TI
Vcc 1 TMS
GND 2 nTRST
nTRST 3 TDI
GND 4 GND
TDI 5 Vcc
GND 6 NC
TMS 7 TDO
GND 8 GND
TCK 9 RTCK
GND 10 GND
TDO 11 TCK
nRST 12 GND
Vcc 13 EMU-0
GND 14 EMU-1


To adapt from standard 20pin header you need an adapter. As example the Lauterbach one:
