Introduction Welcome to Enea Linux Enea Linux is based on the open source configuration system Yocto which is becoming the de facto standard for building and configuring embedded Linux. Yocto development is coordinated by the Yocto Project which was initiated by the Linux Foundation. The Yocto-based development environment of Enea Linux allows you to build embedded Linux kernels and tool chains on a Linux host. It aids you in customizing embedded Linux kernels for a specific hardware architecture, and in building and troubleshooting embedded Linux applications on targets or emulated in QEMU. Enea Linux also provides verified and easily installed board support packages (BSP) for a number of hardware architectures. Each BSP includes a Linux kernel and a root filesystem (rootfs), plus a number of packages that can be extended on request. Providing true open source Linux with customer interests in mind, is the cornerstone for Enea when supplying Enea Linux. We provide: A Yocto compatible environment, familiar for those who have used Yocto from any other distribution. The Enea Linux environment is fully independent from hardware vendor leverage and does not push for a particular hardware architecture. Enea has initiated and contributes the ptest package test framework to the Yocto Project. Enea also uses ptest to verify the packages on target. By using, testing Yocto and sharing Linux patches with upstream projects, Enea assists the open source community in providing mature software in less time. As an Enea Linux user, you are welcome to contribute to the global development of Linux by propagating your Linux patches through Enea. Enea can also assist a customer by analyzing source code and producing valid open source reports, as required by the community when open source components are used.
