This isn't acceptable as it breaks the point of defconfigs, and will break our Travis-CI testing of defconfigs. We need to either make the internal toolchain work with Cortex-M3, or alternatively, make the external toolchain logic support the OSELAS toolchain. I *think* I tried the latter option, but ran into troubles, but I can't remember which ones. > +BR2_TOOLCHAIN_EXTERNAL_GCC_4_9=y > +BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_16=y > +# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS is not set > +BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y Why? > +BR2_TARGET_ROOTFS_INITRAMFS=y > +BR2_GLOBAL_PATCH_DIR="board/stmicroelectronics/stm32/stm32f469-disco/patches/" > +BR2_ROOTFS_POST_IMAGE_SCRIPT="board/stmicroelectronics/stm32/stm32f469-disco/post-image.sh" > +BR2_LINUX_KERNEL=y > +BR2_LINUX_KERNEL_LATEST_VERSION=y > +BR2_LINUX_KERNEL_PATCH="board/stmicroelectronics/stm32/stm32f469-disco/patches/kernel" Not needed since you have BR2_GLOBAL_PATCH_DIR.

Unfortunately, the toolchain built with Buildroot does not currently support this platform. Thus, the tested-working one is being referenced instead. Once the Buildroot toolchain works, this will be swapped out.
