I'm not sure to understand the "At least" here. Also, why don't you want to use distroboot? We precisely try to encourage using distroboot in Buildroot defconfigs, instead of uEnv.txt stuff. So it's a bit going backward to use uEnv.txt here. Could you explain this? > diff --git a/configs/beagleboneai64_defconfig b/configs/beagleboneai64_defconfig > new file mode 100644 > index 0000000000..593c41625c > --- /dev/null > +++ b/configs/beagleboneai64_defconfig > @@ -0,0 +1,50 @@ > +BR2_aarch64=y > +BR2_cortex_a72=y > +BR2_GLOBAL_PATCH_DIR="board/beagleboard/beagleboneai64/patches" > +BR2_DOWNLOAD_FORCE_CHECK_HASHES=y Aren't we supposed to have BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_XYZ=y somewhere?
