10-pin Custom CoreSight (1.27mm) Debug Adapter
|
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to the Cortex based target. It’s used to connect to the embedded target featuring a 20-pin 1.27mm target debug connector with the custom CoreSight 10 pinout. Optionally, connecting the RTCK or the JTAG TRST to pin 7 (KEY pin otherwise) via a jumper makes this debug adapter distinct from the 10-pin 1.27mm CoreSight Debug Adapter (Ordering code IC50116-2).
The following pinout is valid on the target side:

ARM Coresight 10 Custom pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
Jumper J1
Jumper position 1-2: pin 7 = JTAG-TRST
Jumper position 3-2: pin 7 = RTCK
Jumper position floating: pin 7 = KEY (default)
The debug adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10. These fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away.The debug adapter connects to the target via a 10-pin 1.27mm connector, for example SAMTEC FFSD-05-01-N. A target should feature a matching part, for example SAMTEC: SHF-105-01-L-D-TH.

Make sure this adapter fits on your target connector - check Cross Table. |
