1. Connecting S32K344 Evaluation Board to the NAVQ+ Kit
The following hardware setup is required for installing and running a Zephyr sample on the NXP S32K344 Evaluation Board:
...
Pin Function | S32K344 Connector | NAVQ+ Kit Connector |
+5V | P27.1 | J6.1 |

2. Connecting S32K344 Evaluation Board to a Linux PC
The following hardware setup is required for installing and running a Zephyr sample on the NXP S32K344 Evaluation Board:
...
The SEGGER J-Link is connected to the P26 connector (this is a 10 pin 0.50” space JTAG with the standard pinout used by standard Arm debuggers). Ensure pin 1 on the PCB silkscreen is aligned with pin 1 on the debugger (refer to the picture above).
The Ethernet connection to the local network using the RDDRONE-T1ADAPT Ethernet media converter connected to the P9 100Base-T1 Ethernet Connector.
The power is to be supplied at the 5 pin P27 connector at the top left corner of the board (Pin 1-2 power, Pin 3 NC, Pin 4-5 ground). The input voltage range is from 5V to 40V.
