Hi
Please download Multilink Universal/Universal FX Technical Summary Does the S32K3 debugger interface match Multilink Universal and Multilink Universal FX Pinouts - Ports A-H?
FX Note: The USB Multilink Universal FX is capable of providing power (5V or 3.3V) directly to the target processor via the TVCC pin. This removes the need for an external power supply for systems requiring 200mA of current or less. The TVCC pin should be connected even in cases when the target is self-powered.
If you use Multilink FX to power the S32K3 please note that the voltage should be 3.3v, but usually you should not need this feature.
7 Connecting To The Target
The following is the proper connection sequence to connect the PC to the target system via the Multilink interface:
1. Make sure the target power is OFF and the USB Multilink Universal or Universal FX is not connected to either the target or the PC
2. Open the Multilink and connect a ribbon cable from the correct Multilink port to the target. Make sure that the ribbon cable is plugged into the target with the proper orientation. PIN 1 is indicated by a 1 next to the port.
3. Connect the Multilink to the PC via a USB cable. The Blue LED on the Multilink should illuminate.
4. Turn the target power on. The Yellow LED on the Multilink should illuminate.
Before disconnecting the setup, turn the target power off.
Best Regards,
Robin
