Most likely yes, but when I see the fragment, it indeed disables a lot of things, which is nice as it speed up the build. Just like on x86, you could build the full defconfig to have something that boots under qemu, but having a stripped down configuration is a lot more useful/practical; Thomas -- Thomas Petazzoni, co-owner and CEO, Bootlin Embedded Linux and Kernel engineering and training https://bootlin.com _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
