SEGGER Product Demo

This package offers two prebuilt binary files of a SEGGER product demo application to run on an ST STM32F746G-Discovery.

It is prepared for download into internal flash using J-Link without the need for an IDE. An embOS stack-check and profiling library is used.

Download demo

Content of the demo application:

embOS

Shows a list of all the tasks running and provides information about the different tasks.

emFile

This is a combination of emFile and emSecure. This application reads the images (*.bmp and *.jpeg) from the SD Card and displays those files.

Further the emSecure part tries to verify the images with the signatures (*.*.sig). On success the images are getting displayed. On fail the images are getting displayed with a watermark. To have this working properly, please copy the content from \SDCard to an SD card and plug it into the board.

Please make sure the image are in the proper size. The best size is 300x172 pixels. Anything above won't be displayed correctly.

emUSB

This application shows how to realize a touch pad (like known from a notebook) and makes it possible to control the host PCs mouse. To have this application working properly make sure the board is connected via mini USB cable on connector 'CN12 USB_HS'.

emNet

This application shows the network traffic related to the board. It displays received and send bytes. Of course this demo makes only sense if the VNC application is running and an Ethernet cable is connected. Further it shows the IP address of this board once a connection has been established.

VNC

If the 'VNC on startup' version is running, VNC is always on. Otherwise it needs to enabled by tipping on the appropriate button. To connect to the board use a VNC client of your choice and use either the IP address displayed in the emNet application or use 'STM32F746' as connection.

emWin

This application shows a simple user interface to control the color of light bulbs.

Screensaver

If the application without VNC is running a screensaver will be shown after short period of inactivity.

How to run the prebuilt application:

Per default the STM32F746 Discovery boards come with a ST-Link on board debugging probe. This needs to be upgraded to a J-Link OB. To do so please unzip the ST-Link reflash tool from STLinkReflash_161221.zip, start STLinkReflash.exe and follow the instructions.

The most recent version of this tool can be found here: https://www.segger.com/downloads/jlink/STLinkReflash

Once the ST-Link is upgraded follow the steps below.

Make sure power selection jumper on the back of the board is fitted to '5V link'
Connect your target to your host PC with a mini USB cable
Execute StartBinary.bat
Once the download is finished disconnect the USB cable
Set the power selection jumper to 'USB_HS'
Connect a micro USB cable to 'CN12 USB_HS'

Converting ST-LINK on-board into a J-Link

SEGGER offers a firmware upgrading the ST-LINK on-board on the Nucleo and Discovery Boards. This firmware makes the ST-LINK on-board compatible to J-Link OB, allowing users to take advantage of most J-Link features like the ultra fast flash download and debugging speed or the free-to-use GDBServer.

SEGGER SystemView

SEGGER SystemView is a real-time recording and visualization tool that reveals the true runtime behavior of an application, going far deeper than the insight provided by debuggers. This is particularly effective when developing and working with complex systems comprising multiple threads and interrupts: SystemView can ensure a system performs as designed, can track down inefficiencies, and show unintended interactions and resource conflicts.
