Required Hardware

1 Required Hardware
• One Linux computer, or a virtual machine running Linux
• One microSD (2GB+)
• One BeagleBone black board
• One TMDSPLCKITV4 kit
• One FTDI-RS232 bridge
2 Step-by-Step Description
This walkthrough will enable users to build a G3 PLC network with one node. Users can build up a PRIME
PLC network in a similar fashion. Users will also learn how to configure and compile a Linux kernel
required for this task.
Create a Standard Image on an SD Card
The base for this DC image will be the default image provided by the TI SDK. To modify the image:
1. Install the latest SDK on your Linux machine (or virtual machine).
(a) Download the latest SDK, here “ti-sdk-am335x-evm-07.00.00.00-Linux-x86- Install.bin” from
http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html.
(b) Install the package on the Linux machine using a console window.
./ti-sdk-am335x-evm-07.00.00.00-Linux-x86-Install.bin
Use the suggested directory, for example /home/user/ti-sdk-am335x-evm-07.00.00.00/.
NOTE: The abbreviation through the guide for this path is $SDK.
2. Make an SD card (2GB or more) available to the Linux machine and install the standard (pre-built)
image on it.
cd $SDK/bin
sudo ./create-sdcard.sh
Options: Create two partitions and use the pre-built image.
3. If necessary, remove and insert the SD card to mount it properly to the Linux environment.

Step-by-Step Description
Change and Compile the Kernel
You need to change the kernel to add certain components not included in the standard kernel:
1. Make the SDK tool chain path available (Remember $SDK is just an abbreviation and needs to be
replaced with your SDK installation path).
export PATH=$SDK/linux-devkit/sysroots/i686-aragolinux/ usr/bin:$PATH
2. Change to Linux kernel top folder.
cd $SDK/board-support/linux-<ver>
3. Clean kernel directory.
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihftisdk_ am335x-evm_defconfig
4. Configure kernel.
A comfortable GUI easily allows adding of components.
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
The GUI will appear. Add following components to the kernel:
(a) IPv6 functionality
Networking support→Networking options→The IPv6 protocol <*>
(b) Virtual tunnel networking
Device drivers→Network device support→Universal TUN/TAP device driver support <*>
(c) FTDI USB driver to recognize the TMDSPLCKITV4 hardware
Device drivers→USB support→USB Serial Converter Support <*>→USB FTDI Single Port Serial
Driver
(d) Enable USB port on the beagle bone (used as host)
Device drivers→USB support→Inventra Highspeed Dual Role Controller <*>→Platform Glue Layer
<*>→[Separate window]: TI DSPS platforms (x)→Enable support for AM335x devices <*>
Save configuration and exit.
5. Compile kernel
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LOADADDR=0x80008000 zImage
Copy Created Files to the SD Card
The new kernel must be copied to the default installation on the SD card:
1. Remove old kernel and copy new kernel to SD card (assuming you are still in directory kernel top
directory).
sudo rm /media/rootfs_/boot/zImage
sudo ./arch/arm/boot/zImage /media/rootfs_/boot
Enable PLC Modem to Act as DC PHY
The PHY hardware of a DC and the service nodes are exactly the same, which means the
TMDSPLCKITV4 can be used as PHY for the DC:
1. Flash image sysbios_g3_plc_dc_F2806x_AFE031_CRC16_MSB to the PLC modem, which is provided
in the G3 DC software package. See the TMDSPLCKITV4 manual for a description.
2. Connect BeagleBone (P3 [USB]) and TMDSPLCKITV4 (J3 [USB]).
The DC application accepts a UART connection to the PLC PHY hardware by using a virtual com port.
3. Power up the TMDSPLCKITV4.
D2 of the PLC SoM module should blink with a frequency of 1 Hz.
Boot the BeagleBone Black with the SD Card
1. Remove the SD card from Linux computer and insert in BeagleBone board.
2. Connect FTDI USB-RS232 bridge to J1 of the BeagleBone board. The USB connector connects to
your host computer (Linux or window).
3. Open a new console on your host and start a terminal program (for example, minicom). Make sure the
FTDI bridge is tied to it.
4. Apply power to BeagleBone board through the USB socket P4. Press and hold S2 while powering up
the board. The BeagleBone board should boot now. Check the minicom output.

Step-by-Step Description

Copy PLC Software to System
Until now, the BeagleBone software would not recognize PLC software at all. A convenient way is to
connect the BeagleBone board to the Ethernet and copying the data using FTP tool like Filezilla
(assuming the host computer is also connected to the Ethernet).
1. After BeagleBone powers up, log in to BeagleBone board.
am335x-evm login: root
2. Get the IPv4 address of the BeagleBone board.
ifconfig
3. Build a connection from host computer to BeagleBone board using an FTP program.
4. Create a directory, for example G3, in the /home/root directory of your BeagleBone environment.
5. Copy all binaries from the G3 DC software package to the /home/root/G3 directory.
The standard PLC package has a folder SW/bin where all files for the AM335X should be copied. Copy
all files with fragment “AM335x” in the file name to the BeagleBone directory. The latest G3 DC
software package is available for download at http://www.ti.com/tool/TI-PLC-G3-DC.
Running the G3 DC Application
1. Back in the BeagleBone terminal window of your host machine, go to directory G3 and allow execution
of all copied files.
cd G3
chmod +x *
2. Start the G3 application.
./g3_dc_AM335X_aes_msb_loadng.exe –d –c /dev/ttyUSB1
3. You can always check whether the application is running with the command.
ps
4. Now, an SN can join the network using another PLC modem with service node software installed. See
the TMDSPLCKITV4 manual on how to join a network.
Perform a Data Transfer over the Network
Once the SN has joined, you can trigger simple data transfer by using application udpIPv6App_AM335X
./udpIPv6App_AM335x –l 32 –s 0x1
The packet length is 32 bytes and the short address is 0x1. The short address will be assigned to each
joining node starting at 0x1.
The G3 network should now run. These steps will work as well for PRIME standard.
