Profinet® Quick Start Guide on Linux®

Go to the board-specific section below and connect the components as described in the following steps:

SAM9X75 Curiosity LAN Kit

• LAN8840 EDS2 Daughter Card to Gigabit Ethernet J17 connector
• Ethernet cable to RJ45 connector on the LAN8840 EDS2 Daughter Card
• The other side of the Ethernet cable needs to be plugged into the Windows PC
• SD card programmed and inserted into the SD Boot J14 slot
  • The procedure for programming an SD card is provided in a later part of this guide
• Serial to USB dongle to UART DEBUG J35 header on one side and to the PC on the other side
• USB Type-A to Micro-USB cable to J2 Micro-USB port for power
• Jumpers J9 and J10 opened to avoid booting from NAND and QSPI Flash

SAM9X60 Curiosity Kit

• Ethernet cable to RJ45 connector J6
• The other side of the Ethernet cable needs to be plugged into the Windows PC
• SD card programmed and inserted into the SDMMC0 J3 slot
  • The procedure for programming an SD card is provided later in this guide
• Serial to USB dongle to UART DEBUG J11 header on one side and to the PC on the other side
• USB Type-A to Micro-USB cable to J1 Micro-USB port for power
• Jumper J4 opened to avoid booting from NAND Flash

On the PC, open a serial terminal with the following settings:

• Baud Rate: 115200
• Data: 8-bit
• Parity: None
• Stop: 1-bit
• Flow Control: None

Download the ZIP file from SW70F56A and unzip it.

Install the image on the SD card.

Press the RESET button on the board to force a reset.

The Linux image will be booted and a login prompt will be shown in the serial terminal. If not automatically logged in, enter "root" as the login with no password.

The Profinet demo application runs as a systemd service. The status of the application can be checked with the following command:

The console log can be checked with the following command:

Download PRONETA BASIC 3.8 (or higher) from Siemens™ after logging in with a free account. Download the zip file under the downloads section and extract it.

Run PRONETA.exe. If a pop-up asks you to install the Npcap™ driver, click yes. Once the PRONETA window is opened, click on Settings.

Go to the Network Adapter window and select the adapter to which the Profinet device is connected.

Go to the Network Analysis window and select the Online tab. The PC running PRONETA and the device running Profinet demo application will be visible. Both will be connected by a line if the Profinet device already has a valid IP address. The procedure to set an IP address for the Profinet device is explained below. Click on the device to view the Device Details.

Right click on the device and select Start Flashing LED. The LED on the development kit will blink three times at a frequency of 1 Hz. It will continue to do so with a short break each cycle until you right click on the device and select Stop Flashing LED.

Right-click on the device and select Set Network Parameters to change the device’s name and IP address.  To persist the change across reboot, select Apply settings permanently.

Install the following packages on the Linux PC:

Clone the necessary repositories.

Create an empty directory to hold the workspace:

Use the repo tool to fetch all the required repositories:

Edit the EXTERNALSRC path in SW70F56A/meta-pnet/recipes-pnet/pnet-demo/pnet-demo_1.0.bbappend to point to the absolute path of SW70F56A/src.

Copy SW70F56A/meta-pnet to yocto-dev.

Initialize the build environment.

The meta-mchp repository provides sample configuration templates that help set up BitBake™ layers and key configuration files in the Yocto Project build directory.

Set the TEMPLATECONF environment variable to point to the appropriate configuration template before initializing the build environment:

 Go to the yocto-dev directory and initialize the Yocto Project build environment:

To enable the meta-pnet layer during the build, edit yocto-dev/build/conf/bblayers.conf to add the meta-pnet layer.

To add the Profinet demo application and SNMP server to the image, add the following line at the bottom of the file yocto-dev/build/conf/local.conf.

Set the target machine and build the image.

Depending on the target machine, execute any one of the following commands:

Go to the yocto-dev directory. Build the project:

The SD card image with the wic extension can be found in yocto-dev/build/tmp-glibc/deploy/images/ folder.

Install the following packages on the Linux PC:

Clone the necessary repositories:

Fetch the required repositories:

Checkout the latest release branch:

Copy SW70F56A/pnet-br to buildroot-external-microchip/package.

Add the following line to buildroot-external-microchip/Config.in:

Initialize the build environment:

Go to the buildroot-mchp directory. Setup BR2_EXTERNAL.

 Run the defconfig for your board by executing any one of the following commands:

Now, open the Buildroot configuration menu:

Enable the following packages:

• p-net: Navigate to External Options > pnet and press y. This will expose the "pnet repo path or URL" option. Add the full path to the SW70F56A/ folder.
• snmp: Navigate to Target packages > Networking applications > netsnmp and press y.

Save and exit the configuration.

Build the project:

The SD card image can be found in folder buildroot-mchp/output/images/sdcard.img
