Requirements

To install a Digi Embedded Yocto toolchain you need a development machine with at least:

Linux 64-bit system (Ubuntu 14.04 or Ubuntu 16.04)
4 CPU cores
4 GB of RAM
Between 2 GB and 10 GB of free disk space, depending on platform

Note Before starting development for your ConnectCore platform, make sure your device is correctly connected, powered, and running. See Step 2: Set up the hardware and Step 3: Program the Yocto firmware.

Download and install the toolchain

Digi Embedded Yocto provides a pre-compiled C/C++ toolchain that matches the default dey-image-qt image. You can use it to cross-compile applications to run on Digi embedded platforms, including graphical GTK or QT5 applications.

To install new Digi Embedded Yocto toolchains in your system, follow these steps:

Download the toolchain installer from the Digi support page.

wget ftp://ftp1.digi.com/support/digiembeddedyocto/2.2/r3/sdk/ccimx6ulsbc/x11/dey-glibc-x86_64-dey-image-qt-x11-cortexa7hf-neon-toolchain-2.2-r3.sh

Note You can also use your own pre-compiled toolchains.

Give execution permission to the installer.

chmod +x dey-glibc-x86_64-dey-image-qt-x11-cortexa7hf-neon-toolchain-2.2-r3.sh

Install the toolchain on your host PC.

./dey-glibc-x86_64-dey-image-qt-x11-cortexa7hf-neon-toolchain-2.2-r3.sh
