![]() ![]() There are cases where it is simply more practical to download the linux kernel source and headers for the version you're interested in directly from (a pretty reliable URL/site that isn't going away ) See "Obtaining the kernel sources for an Ubuntu release using git" in Ubuntu Wiki Kernel Source Code. You can get the version you want from git, but you're in for a big download.Put them in a new directory, unpack with dpkg-source -x *.dsc.Scroll down, click the "Source:" link, you're on the Package Source Page now. That should give you the Launchpad Package Page for that version. Say you need kernel source for 3.19.0-58 :Īpt-get source linux-image-3.19.0-58-generic will get the source for the latest kernel in the series: 3.19.0-80 in this case, which is not what you asked for.ġ) Give up, install kernel 3.19.0-80 and use apt-get source Deploy the Toradex Easy Installer Image: You may now use the above prepared Toradex Easy Installer package with the Toradex Easy Installer.Strangely enough everyone recommends apt-get source which doesn't work most of the time if you're looking for a specific kernel version:.You may, of course, also change any of the other properties as documented in the Toradex Easy Installer article on our developer website. Adjust image.json: Now adjust the image.json to your linking (e.g., change at least the name and description for you to distinguish it from our original package).Integrate Artifacts: Integrate the above-built artifacts into the downloaded embedded Linux image by replacing the kernel binary and device tree(s) in the archive.Choose the appropriate image for your SoM in the Reference Images for Yocto Project Software Downloads Start from a Existing Sample Image: Download and extract one of the Toradex prebuild images.Deploying the Kernel to an Image įollow the steps below to update your Kernel using Toradex Easy Installer. Run depmod on the target after deploying new or changed kernel modules. Upstream-based Kernel SoCīuilding Linux Kernel Download the Linux Kernel Source The development of the Kernel is made in the master branch for the upstream-based modules and the tags represent versioning checkpoints where we ensure the functioning of builds and features. There you will find the version information of the Linux kernel, U-Boot, Yocto/OpenEmbedded, the Toradex BSP, and Linux images, along with release dates. The required git branch and Linux binaries to be used depend on module type and BSP version, as we will explain in this article.įor a high-level overview of the BSP Versions, check out our Embedded Linux Release Matrix. You can follow the U-Boot building instructions as explained further in this article, and after that, include it in PATH. Select the correct one from the tabs below:Īlternatively, mkimage tool is also built during the U-Boot compilation. You have to choose to download either the 32 bit or 64 bit Arm cross-toolchain, according to the architecture of your Computer on Module SoC. Use version 9.2 of the Arm releases binary toolchains to cross-compile software for Toradex modules: Prepare the Host Machine for Cross-Compilation Install the necessary tools and dependencies as explained in the section Install Tools and Dependencies.Follow the steps in the section Install the GNU Toolchain for Hard Float Calling Convention.Follow the steps described in the article Build U-Boot from Source Code (optional).This content is available at BSP Layers and Reference Images for Yocto Project Software. Understand the basic concepts of Toradex Embedded Linux offerings, such as release cycles, distributions and images. ![]() Build Device Tree Overlays from Source Code.Check the following articles if you are looking for information about: This is the second article of a three-part series about building from source code. The Linux kernel is available on our Git server at. If this is the case, see the specific article Kernel Driver Backports Integration. You might also need to compile the Linux kernel driver backports. We provide OpenEmbedded recipes that build U-Boot and Linux as part of a complete BSP image hence if you plan to build a full BSP image, follow the Build a Reference Image with Yocto Project/OpenEmbedded article. ![]() This procedure mostly makes sense during Linux development. ![]() This article describes how to build the Linux kernel without using a higher-level build system such as the Yocto Project/OpenEmbedded.
