One Build to Rule Them All: Building FreeRTOS & Linux Using Yocto
Talkat Open Source Summit Europe + Embedded Linux Conference Europe 2019 · on Tuesday, 2019-10-29· at 11:30· Forum 3·
summary
Claims a single Yocto/OpenEmbedded workflow builds FreeRTOS and Linux together by adding a meta-freertos layer, a FreeRTOS app class/recipes, and multi-config wiring so one bitbake invocation produces both artifacts. Uses bitbake, OpenEmbedded test-image infrastructure, multiconfig builds, QEMU (versatilepb and x86_64), and the ARM cross toolchain with newlib and libgloss. Demonstrates building a FreeRTOS ELF, running it in QEMU, and passing automated tests (counts periodic task runs), proving the setup works end-to-end.
