5.1 Debug Basics

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

Three options to start debugger:

If the “Debug Configuration” has not been closed, click on “Debug” button on bottom right
Select Run → Debug (or hit F11)

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

NextProject and Tutorials: Introduction to OpenSDA

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 Firmware Apps. S32K146EVB-Q144 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.

Enter OpenSDA Bootloader Mode Load an OpenSDA Application

Unplug the USB cable if attached.
Set J104 on position 1-2
Press and hold Reset (SW5)
Plug in a USB cable (not included) between a USB host and the OpenSDA USB connector (labeled “SDA”)
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 OpenSDA bootloader mode.

Important Note: Follow the “Load an OpenSDA Application” instructions to update the MSD Flash Programmer on your S32K146EVB-Q144 to the latest version.

While in OpenSDA bootloader mode, double click SDA_INFO.HTML in the BOOTLOADER drive. A web browser will open the OpenSDA homepage containing the name and version of the installed application. This information can also be read as text directly from SDA_INFO.HTML
Locate the Firmware Apps
Copy and Paste or drag and drop the MSD-Debug-S32K146EVBQ144_Pemicro_v121.SDA to the BOOTLOADER drive
Unplug the USB cable and plug it in again. The new OpenSDA Application should now be running and a S32K146 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 Firmware Apps.

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 S32K146 MCU. It emulates a FAT16 file system, appearing as a removable drive in the host file system with a volume label of S32K146EVB-Q144.

Raw binary and Motorola S-record files that are copied to the drive are programmed directly into the flash of the S32K146 and executed automatically. The virtual serial port enumerates as a standard serial port device that can be opened with standard serial terminal applications.

Using the MSD Flash Programmer Using the Virtual Serial Port

Locate the .srec file of your project, file is under the Debug folder of the S32DS project
Copy and paste or drag and drop one of the .srec files to the S32K146EVB-Q144 drive

The new application should now be running on the S32K146 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 S32K146 EVB board over USB to reprogram the preloaded code example to another example.

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.

Determine the symbolic name assigned to the EVB-S32K146 virtual serial port. In Windows open Device Manager and look for the COM port named “PEMicro/Freescale - CDC Serial Port”
Open the serial terminal emulation program of your choice. Note: For Windows you can use Tera Term, PuTTY or HyperTerminal
Press and release Reset (SW0) to any time to restart the example application. Resetting the embedded application will not affect the connection of the virtual serial port to the terminal program
It is possible to debug and communicate with the serial port at the same time. There is no need

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
