26-pin 2.54 mm NXP ColdFire
|
This debug adapter is used to connect the iC5000 BlueBox to NXP ColdFire based target featuring a 26-pin 2.54 mm pitch target debug connector with the ColdFire pinout.
|
This debug adapter is supported by the iC5000 BlueBox only. |
The debug adapter connects to the 25cm 40-pin ribbon cable coming from the BlueBox and to the target debug connector on the other side. Refer to the BlueBox User Manual for more details on connecting the debug adapter.
The following pinout is valid on the target side:

26-pin ColdFire target pinout
Blue colored signals are trace signals.
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. |
26-pin 2.54 mm NXP ColdFire Debug Adapter features resettable fuses on pins 2, 4, 7, 8, 9, 10, 24 and 26. These protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away. Signals on pins 1, 12-19 and 24 are protected via 47 ohm serial resistors.
The debug adapter connects to the target via a 26-pin 2.54 mm connector, for example Yamaichi FAS-26-17. A target should feature a matching part, for example WÜRTH ELEKTRONIK 61202621621.
