3.1 Set Up Jumpers

3.2 Plug In the Power Supply

The S32K148-EVB evaluation board powers from a USB or external 12 V power supply.
USB power can be enabled with J8 (2-3) and J18 (2-3).

1. Connect the USB cable to a PC using supplied USB cable.
   
2. Connect other end of USB cable (microUSB) to micro-B port on S32K148EVB at J24.
   
3. Allow the PC to automatically configure the USB drivers if needed.
   

Debug is done using OpenSDA through J24.

When powered using the USB, LED D10 should light green and LEDs DS2 and DS3 light orange.

Note: Once the board is recognized, it should appear as a mass storage device in your PC with the name S32K148EVB.

4.1 Communicate with Debugger

1. Launch the FreeMASTER application.
2. Configure the communication port through OpenSDA with a 115200 b/s speed rate:
   • To do this manually, go to Project > Options > Comm.
   • To do this automatically, go to Tools > Connection Wizard.

Create an Example from the SDK

The S32 Design Studio IDE includes a software development kit (SDK) for quickly developing applications on S32K1xx devices.

1. To get started, go to File > New > S32DS Project from Example.
2. Go to the S32K14x EAR SDK v0.8.6 Example Projects section and select the example you want to use. (in this case, the “hello_world” example is selected). Then click Finish.
3. The new project is created in the workspace. Click the generate code icon and then click the debug icon.

Note: If run correctly, the LED should start blinking red and green.

The complete documentation of the SDK can be found in:

C:\NXP\S32DS_ARM_v2018.R1\S32DS\S32SDK_S32K14x_EAR_0.8.6\doc\Start_here.html

Check Enabling Technologies: Hands-On Workshop: S32 SDK for S32K for more information about the use of the SDK.

Debug Basics

Debug configuration is only required once. Subsequent starting of debugger does not require these steps.

There are three options for starting the debugger:

• If the debug configuration is still open, click Debug on the bottom right.
• Select Run > Debug

• Press (F11)

  

Note: This method currently selects the desktop target (project.elf) and gives an error. Do not use until this is changed.

Recommended: Cpck the down arrow on the bug icon and select … _debug.elf target

Step, Run, Suspend and Resume

• Step Into (F5)

  

• Step Over (F6)

  

• Step Return (F7)

  

• Run

  

• Suspend

  

• Resume (F8)

  

• View Variables

Click the Variables tab.
To enter different values, click in the Value field.

View and Alter Registers

To see CPU registers, click the Registers tab. To enter different values, click in the Value field.

"Click on a value to allow typing in a different value."
To see peripheral registers, click the EmbSys Registers tab.

Introduction to OpenSDA

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.

S32K148 EVB comes with the MSD Flash Programmer + Debug OpenSDA application preinstalled.

Follow these instructions to run the OpenSDA Bootloader and update or change the installed OpenSDA application.

The MSD flash programmer + Debug is a composite USB application that provides a virtual serial port, a debug interface and an easy and convenient way to program applications into the S32K MCU. It emulates a FAT16 file system, appearing as a removable drive in the host file system with a volume label of S32K148EVB.

Raw binary and Motorola S-record files that are copied to the drive are programmed directly into the flash of the S32K148 and executed automatically. The virtual serial port enumerates as a standard serial port device that can be opened with standard serial terminal applications.

Using Ethernet on the S32K148EVB

Different from the rest of the devices on the S32K1xx family, the S32K148 has the ENET module, which offers the possibility to use Ethernet communication protocol. This enables this device for applications such as small Gateway (LIN-CAN-ETHERNET) or Audio Amplifier.

The software development kit (SDK) for the S32K1xx devices offers a middleware Ethernet stack (LwIP), that allows the user to develop applications faster.

Default Configuration

Get Started with the S32K148EVB - PT3A

Get Started with the S32K148EVB - PT3A

There is no Ethernet PHY on the board. In order to use ENET, you must get S32K148EVB-KIT, including both S32K148EVB-Q176 with ADTJA1101-RMII Ethernet Adapter in order to use ENET, as there is no Ethernet PHY on the board.

Running ENET

The TCP/IP ENET example is available in the S32K1xx SDK only in version EAR 0.8.6 and higher.

In order to get the example working, you need:

• S32K148EVB-KIT = S32K148EVB + ADTJA1101-RMII
• Media converter: automotive Ethernet to 10/100 Base-TX
• SDK version "S32K_SDK_EAR_0.8.6" or higher
• Any program able to set up a TCP client, like SocketTest

Before trying the example, change the IP of your computer to a static IP address. To do this, go to the network adapter settings of the computer, right click the local area network and select Properties.

Select the option Internet Protocol Version 4 (TCP/IPv4) and click Properties.

The SDK example assigns an IP value of 192.168.0.200 to the S32K148.
The computer must have an IP in the same network. Fill out the values and click OK.

Once the PC setup is done, import the SDK example into the S32DS.
Go to File > Create new project from example option:

Compile the example and download it to the S32K148 EVB with the ADTJA1101-RMII connected.
The media converter should also be connected between the board and the computer:

Once you have everything connected, run the example. It should not have any issue. There are two ways to verify that the example is correctly running:

• Ping the board. using the windows command of the windows console.
  Use the command ping 192.168.0.200 and the board should answer:

• Use the SocketTest program to echo the board at a TCP level.
  Open the SocketTest (or the TCP client program you are using), using IP address: 192.168.0.200 and Port: 7.

The connection should be established without any issue.
Once the computer is connected with the S32K148, you can send any message and the S32K148 will make an echo of anything you send.

Using SPI on the S32K148EVB

Different from the rest of the devices on the S32K1xx family, the S32K148 has the QuadSPI module, which offers the possibility to communicate with external devices (mostly memories) that allow QuadSPI protocol.

The S32K148 EVB has a MX25L6433F external memory mounted on the board.

The software development kit (SDK) for the S32K1xx devices offers an example for communicating with the external memory mounted on the board. Just run it and start testing the module.
