Choosing the right Embedded Linux platform for your next project
summary
Qt 5.5/5.6 support expands multiple Linux backends but real projects hit platform-specific gaps: full‑screen eglfs works only with matching vendor backends (missing one causes “Could not create the egl surface” crashes), NVIDIA requires EGL stream extensions, multiple displays need DRM/KMS, and combo boxes can abort on non‑compositing systems. Input defaults to libinput in 5.6. Multimedia requires hardware‑accelerated video via GStreamer 1.0. Use Yocto/buildroot recipes and test on the actual board early.
