Das byteENGINE AM335x Custom ist ein leistungsfähiges Industrial Computing Modul, das höchsten Ansprüchen gerecht wird und individuell bestückt werden kann. Es ermöglicht eine kurze time-to-market bei gleichzeitiger Reduzierung der Entwicklungskosten. Unter Berücksichtigung spezifischer Anforderungen sind ebenfalls Designrisiken erheblich reduziert.

Das System-on-Module (SOM) verwendet den industriellen Anwendungsprozessor AM335x von Texas Instruments mit wahlweise 300/600/800/1000 MHz. Darüber hinaus verfügt das AM335x Custom über eine PowerVR™ SGX-3D-Grafikbeschleunigung.

Das integrierte SDRAM ist mit bis zu 512 MB verfügbar. Zusätzlich kann das Modul mit 8 GB eMMC oder 256 MB NAND ausgestattet werden.

Die programmierbare Real-Time Unit und das Industrial Communication Subsystem (PRU-ICSS) ermöglichen einen unabhängigen Betrieb des ARM® Cortex®-Prozessors. PRU-ICSS ermöglicht Echtzeitprotokolle wie EtherCAT, PROFINET, EtherNet / IP, PROFIBUS, Ethernet Powerlink und Sercos.

This section describes briefly the advantages of the compatible operating system (OS) Yocto Project. Furthermore, you will find information about how to create a bootable SD-Card with a prebuilt image by bytesatwork, how to install the prebuilt toolchain with an example and delivers links to the provided Yocto-layers.

  4. Yocto Layer
  1. Supported OS

The Yocto Project (YP) is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture. Bytes at work is part of the Yocto Project and provides specific solutions for your specific applications. bytesatwork provides furthermore the necessary tools for a quick and productive test run.
Here are some highlights for the Yocto Project:

  • Provides a recent Linux kernel along with a set of system commands and libraries suitable for the embedded environment.
  • Makes available system components such as X11, GTK+, Qt, Clutter, and SDL (among others) so you can create a rich user experience on devices that have display hardware. For devices that do not have a display or where you wish to use alternative UI frameworks, these components need not be installed.
  • Creates a focused and stable core compatible with the OpenEmbedded project with which you can easily and reliably build and develop.
  • Fully supports a wide range of hardware and device emulation through the QEMU Emulator.
  • Provides a layer mechanism that allows you to easily extend the system, make customizations, and keep them organized.
  1. Creating SD-Card

To accelerate the starting process bytesatwork provides a prebuilt image. This allows you to start a complete Yocto System from a microSD-Card. Here you will find information about how to write the prebuilt image to a microSD-Card in order to create a bootable image:

* Windows *
- Unzip the <file.wic.gz> (e.g. with 7-zip)
- Write the resulting <file.wic> to the uSD-card with a tool like Roadkil's Disk Image[https://www.roadkil.net/program.php?ProgramID=12]

* Linux *
- gunzip -c <file.wic.gz> | dd of=/dev/mmcblk0 bs=8M conv=fdatasync status=progress
- To improve write performance, you could use bmap-tools:
  bmaptool copy <file.wic.gz> /dev/mmcblk0
  1. Initial SDK / Toolchain

In the Yocto Project development environment, toolchains are used to build the image and applications that run on the target hardware. You can install a prebuilt toolchain with just a few commands:

1) Download the Toolchain and install it
# sudo ./poky-bytesatwork-glibc-x86_64-devbase-image-bytesatwork-armv7at2hf-neon-bytepanel-toolchain-3.0.1.sh

2) Source the Toolchain
# source /opt/poky-bytesatwork/3.0.1/environment-setup-armv7at2hf-neon-poky-linux-gnueabi

3) Check if Cross-compiler is available in environment:
# echo $CC
# arm-poky-linux-gnueabi-gcc -march=armv7-a -mthumb -mfpu=neon -mfloat-abi=hard --sysroot=/opt/poky-bytesatwork/3.0.1/sysroots/armv7at2hf-neon-poky-linux-gnueabi

4) Crosscompile the source code, e.g. by:
# $CC helloworld.c -o helloworld

5) Check generated binary:
# file helloworld
# helloworld: ELF 32-bit LSB pie executable, ARM, EABI5 version 1

6) Copy the binary to the target, e.g. by scp:
# scp helloworld root@<ip of bytepanel>:

7) Login to target by user root, password rootme:
# ssh root@<ip of bytepanel>

8) Run helloworld on target:
root@bytepanel:~# cd /root; ./helloworld
  1. Yocto Layers

Layers support the inclusion of technologies, hardware components, and software components. bytesatwork provides on GitHub the according layers to build a Yocto Based operating system (OS) efficiently. You can find the layers at the following links:

Generic layer:
Yocto branch zeus: https://github.com/bytesatwork/meta-bytesatwork.git

Platform specific layer:
Yocto branch zeus: https://github.com/bytesatwork/meta-bytesatwork-ti.git

Build your own image by using the repo tool:
Yocto branch zeus, https://github.com/bytesatwork/bsp-platform-ti/
