34-pin ERF8 MPC5x/SPC5x target pinout
Blue colored signals are Aurora trace signals.
The JCOMP is an optional pin. Some microcontrollers don’t have this pin. Internally, this is actually the JTAG TRST, which resets the JTAG TAP state machine. Because the JTAG TAP state machine can be reset also by the TMS and the TCK, this pin is optional also for the debugger. If the microcontroller has the JCOMP pin but it is not connected to the target debug connector, it must be set to the non-active state in the target via a pull-up resistor. If not, then the JTAG TAP state machine remains in reset and debugging is not possible.
Signal direction definition:
O - Output from the Active Probe to the target microcontroller
I - Input to the Active Probe from the target microcontroller
B – mDIO port marked as TRIG on the housing
mDIO port provides two digital signals, which can interact with the embedded target. Each can be configured either for input or output operation.

C – The indicator light provides the status of the Active Probe as follows:
|
Permanently green – Powered on and ready to use. |
|
Blinking green – Establishing connection with the BlueBox. |
|
Blinking blue – Reprogramming SPLASH. |
|
Permanently magenta – Golden image loaded and ready to use. |
D – FNet connector, that connects the Active Probe to the iC7max or iC5700. The FNet cable is delivered with the Active Probe.
|
When powering on the system, switch the BlueBox on before powering on the target. When powering down the system, power off the target before powering off the BlueBox! Use only original accessories for powering and connecting with the BlueBox. Consult with technical support before attempting to use any other accessory. |
Target connector
The target should feature a matching part, for example, Samtec part number: ASP-137973-01.
