S32K142 EVB RevC. LIN Phy errata.
•Errata: the LIN phy on S32K142EVB is connected to S32K142’s pins 32/31 which don’t support
LPUART.
•Workaround: Connect MCU’s pin 29 to LIN Phy’s LIN_TX trace and MCU’s pin 30 to LIN Phy’s
LIN_RX trace at PCB level. This can be done by removing R131 and R130, connecting pad 1 of
R132(DNP) to pad 2 of R131 and pad 2 of R130 to MCU’s pin 30 via, as shown below.
Note: this errata is already fix on
newest EVB version.

Step 1: Power up the Board –EVB Power Supplies
•The S32K142-EVB evaluation board powers from a USB
or external 12V power supply. By default USB power is
enabled with J107 (check slide 5)
•Connect the USB cable to a PC using supplied USB
cable .
•Connect other end of USB cable (microUSB) to mini-B
port on S32K142-EVB at J7
•Allow the PC to automatically configure the USB drivers if
needed
•Debug is done using OpenSDA through J7

Introduction to OpenSDA:1 of 2
OpenSDA is an open-standard serial and debug adapter. It bridges serial and debug communications between a USB host and an
embedded target processor. OpenSDA software includes a flash-resident USB mass-storage device (MSD) bootloader and a
collection of OpenSDA Applications. S32K142 EVB comes with the MSD Flash Programmer OpenSDA Application preinstalled.
Follow these instructions to run the OpenSDA Bootloader and update or change the installed OpenSDA Application.
IMPORTANT NOTE: Follow the “Load an OpenSDA
Application” instructions to update the MSD Flash
Programmer on your S32K142 EVB to the latest
version.
Enter OpenSDA Bootloader Mode
1. Unplug the USB cable if attached
2. Set J104 on position 1-2.
3. Press and hold the Reset button (SW5)
4. Plug in a USB cable (not included) between a
USB host and the OpenSDAUSB connector
(labeled “SDA”)
5. Release the Reset button
A removable drive should now be visible in the host
file system with a volume label of BOOTLOADER.
You are now in OpenSDABootloader mode.
Load an OpenSDA Application
1. While in OpenSDA Bootloader mode, double-click
SDA_INFO.HTML in the BOOTLOADER drive. A web
browser will open the OpenSDAhomepage containing the
name and version of the installedApplication. This
information can also be read as text directly from
SDA_INFO.HTML
2. Locate the OpenSDA Applications
3. Copy & paste or drag & drop the MSD Flash Programmer
Application to the BOOTLOADER drive
4. Unplug the USB cable and plug it in again. The new
OpenSDAApplication should now be running and a
S32K142 EVB drive should be visible in the host file
system
You are now running the latest version of the MSD Flash
Programmer. Use this same procedure to load other OpenSDA
Applications.

Introduction to OpenSDA: 2 of 2
The MSD Flash Programmer is a composite USB application that provides a virtual serial port and an easy and convenient way to
program applications into the S32K142 MCU. It emulates a FAT file system, appearing as a removable drive in the host file system with
a volume label of EVB-S32K142. Raw binary and Motorola S-record files that are copied to the drive are programmed directly into the
flash of the KEA and executed automatically. The virtual serial port enumerates as a standard serial port device that can be opened with
standard serial terminal applications.
NOTE: Flash programming with the MSD Flash Programmer is
currently only supported on Windows operating systems.
However, the virtual serial port has been successfully tested on
Windows, Linux and Mac operating systems.
Using the MSD Flash Programmer
1. Locate the .srec file of your project , file is under the
Debug folder of the S32DS project.
2. Copy & paste or drag & drop one of the .srec files to
the EVB-S32K142 drive
The new application should now be running on the
S32K142 EVB. Starting with v1.03 of the MSD Flash
Programmer, you can program repeatedly without the
need to unplug and reattach the USB cable before
reprogramming.
Drag one of the .srec code for the S32K142. the S32K142
EVB board over USB to reprogram the preloaded code
example to another example.
Using the Virtual Serial Port
1. Determine the symbolic name assigned to the EVB-S32K142
virtual serial port. In Windows open Device Manager and look
for the COM port named “PEMicro/Freescale –CDC Serial
Port”.
2. Open the serial terminal emulation program of your choice.
Examples for Windows include Tera Term, PuTTY, and
HyperTerminal
3. Press and release the Reset button (SW5) at anytime to
restart the example application. Resetting the embedded
application will not affect the connection of the virtual serial
port to the terminal program.
4. It is possible to debug and communicate with the serial port
at the same time, no need to stop the debug.
NOTE: Refer to the OpenSDA User’s Guide for a description of a known
Windows issue when disconnecting a virtual serial port while the COM
port is in use.
