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 JTAG header you need a adapter. As example the Lauterbach one:
