--- title: "What's next" --- # What's next The Embedded Linux functions that are not built yet, grouped by the vendor tool or area they replace. Everything below is **not built**. Nothing on this page can be used today. Beyond these, every built capability still has to run on Windows, against a real build server, on Wind River Linux and on real boards before it moves past modelled (see each page's state). ## Within the areas already built - Writing kas files (layer changes on a kas build are pointed to the kas file, not written there). - `bitbake-layers show-cross-depends`, `flatten`, `layerindex-fetch`, `save-build-conf` and `yocto-check-layer`. - Completion in BitBake recipes. - Resolving `KERNEL_FEATURES` (Wind River and Yocto kernel-cache `.scc` features); `menuconfig` embedded in the editor. - `devtool runqemu`. - `devtool sdk-update` for an extensible SDK; running `devtool ide-sdk` (its CMake preset is already read). - The LTTng Disk I/O and Kernel Memory views. - Buildroot `legal-info` in the licence review. - MISRA C++ checks. - Memory, disassembly and instruction breakpoints on 64-bit targets (the shared debug session writes 32-bit addresses). ## Wind River Linux, Workbench and Studio - Platform project setup with `setup.sh` (machines, templates, distros, layers); Wind River Linux is only recognised today. - Workbench Project Explorer for a platform project. - User Space Configuration: packages and package groups of the image. - Workbench-style application debug with several processes (gdbserver debug covers part of it). - Kernel-mode debug over KGDB. - On-chip JTAG debug with Wind River probes. - System Viewer event traces for Linux (the ftrace and LTTng views cover the Linux side). - Workbench's own Memory Analyzer, Performance Profiler and Code Coverage views (Valgrind, perf and gcov cover the Linux side). - Linux Assembly Tool (`appsdk`: `genimage`, `gensdk`, `genrpm`, `publishrpm`, `geninitramfs`, `gencontainer`, `genyaml`). - Binary distribution: RPM or DEB package feeds and OSTree-based images. - OSTree upgrade of a deployed target. - meta-wr-sbom SBOM generation run from the editor (reading it is built). - Wind River Scanning Tool: SBOM upload, CVE dashboard and team triage. - Rolling cumulative patch layer (RCPL) updates. - Wind River's per-package CVE database. - Out-of-tree kernel module projects. - The build properties dialog (build spec, defines, include paths, toolchain). - eLxr Pro, Wind River's Debian-derived distribution. - Import of Workbench's Eclipse keymap, perspectives, launch configurations and target connections. ## Yocto Project - `devtool menuconfig` for Kconfig-based recipes. - `devtool build-image`. - `devtool ide-sdk` per recipe. - Dependency graphs (`bitbake -g`): why a package is in the image. - Toaster's functions: projects and New Project; project configuration (machines, distros, layers, image and software recipes, variables); layer import and details; custom images by package selection; the build dashboard; recipes, packages and tasks of a build with shared-state reuse; build time, CPU time and disk I/O per task; image contents and why each package is there; recent and per-project builds; command lines of builds started outside it. - Extensible SDK workflows (`populate_sdk_ext`, `devtool sdk-update`, `sdk-install`, `build-sdk`). - Kernel metadata (`KERNEL_FEATURES`, `.scc` files). - Kernel patches and out-of-tree modules (reachable through devtool, not verified on linux-imx). - U-Boot recipe work (`UBOOT_MACHINE`, configuration, environment). - `oe-selftest`. - Error reports (`report-error` class). ## NXP i.MX - Config Tools for i.MX: the Pins tool (`.dtsi` output) and the DDR tool. - Secure boot: HAB and AHAB with `imx-mkimage` and the Code Signing Tool. - Cortex-M firmware beside Linux through remoteproc. ## TI Processor SDK Linux and Code Composer Studio - The Yocto build with TI's layer setup. - The SDK's top-level makefile for kernel, U-Boot and device trees. - SD card and flash writing (`create-sdcard.sh`, DFU, flash writers). - SysConfig pinmux to `devicetree.dtsi`. - Code Composer Studio's Remote Explorer, GDB setup and kernel debugging. - The R5F and M4F cores beside Linux. - Secure boot on HS-SE devices (signing, `binman`, OTP keywriter). ## AMD PetaLinux, EDF and Vitis - `petalinux-create` from a BSP or template, with apps and modules. - `petalinux-config -c kernel` and `-c u-boot` (the root file system configuration is built). - Application and module templates, `petalinux-devtool`. - Device tree: generated PL nodes from the XSA and `system-user.dtsi`. - Bootgen (`.bif` to `BOOT.BIN`, authentication and encryption). - Vitis Unified IDE: Linux applications, Target Connections, TCF agent remote debug (gdbserver debug covers part of it). - RPU (Cortex-R5F) applications with OpenAMP beside Linux. - XSDB and Vitis JTAG debug of FSBL, U-Boot and the kernel. - PetaLinux to EDF migration. ## ST OpenSTLinux and STM32Cube tools - The OpenSTLinux Developer Package (TF-A, OP-TEE, U-Boot and kernel built outside Yocto). - STM32CubeMX device trees for kernel, U-Boot and TF-A with user sections. - STM32CubeIDE MPU projects and Linux-side debug (gdbserver debug covers part of it). - Cortex-M coprocessor firmware loaded through remoteproc. -
