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

Step 1: Power up the Board – Is it powered on correctly ?

• When powered through USB, LEDs D2 and D3 should light green

• Once the board is recognized, it should appear as a mass stor age

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 Bootloaderand 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 dr i ve 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 Bootloadermode, double-click
SDA_INFO.HTML in the BOOTLOADER drive. A web
browser will open the OpenSDAhomepag e contai ning t he
name and version of the installed Application. 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 v er s ion of the M SD Flash
Programmer. Us e 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 wit h v1.03 of the M SD Flash
Programmer, you can progr am repeate dly w ithout 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 as si g ned 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 y our 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. Reset ting the embedde d
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.
