Requirements
To install a Digi Embedded Yocto toolchain, you need a development machine with at least:
- 
Linux 64-bit system (Ubuntu 18.04) 
- 
4 CPU cores 
- 
4 GB of RAM 
- 
Between 2 GB and 10 GB of free disk space, depending on platform 
| 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
| If you already installed a toolchain with the Digi Application Development Environment, you do not need to download and install it again. | 
Digi Embedded Yocto provides a pre-compiled C/C++ toolchain that matches the default image artifact. 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. (You can also use your own pre-compiled toolchains.) ~$ wget https://ftp1.digi.com/support/digiembeddedyocto/3.0/r4/sdk/ccimx8mm-dvk/xwayland/dey-glibc-x86_64-dey-image-qt-xwayland-aarch64-ccimx8mm-dvk-toolchain-3.0-r4.sh
- 
Give execution permission to the installer and install the toolchain on your host PC. ~$ chmod +x dey-glibc-x86_64-dey-image-qt-xwayland-aarch64-ccimx8mm-dvk-toolchain-3.0-r4.sh ~$ ./dey-glibc-x86_64-dey-image-qt-xwayland-aarch64-ccimx8mm-dvk-toolchain-3.0-r4.sh
