BeagleBoard JTAG Adapter by TI
From eLinux.org
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:
