I encountered two problems when building the raspberrypi-64 system:

First. As shown in the attached "log.do_install.20063",
in the "do_install" process, There is no "kernel/arch/arm64/boot/dts/broadcom/../overlays" directory in "build/tmp/work/raspberrypi3_64-agl-linux/kernel-devsrc/1.0-r0/image/usr/src",
but in "build\tmp\work\raspberrypi3_64-agl-linux\kernel-devsrc\1.0-r0\image\usr\src\kernel\arch\arm64\boot\dts\broadcom\Makefile" has such a sentence: "dts-dirs += ../overlays",
and there is no prompt to download the error when downloading this source.

Second. As shown in the attached "log.do_rootfs.5642",
it seems that the source code is missing some files, which also causes me to continue to build the system.

The commands I built are as follows:
Source meta-agl/scripts/aglsetup.sh -m raspberrypi3-64 -b build agl-all-features agl-ci-snapshot-features agl-audio-soundmanager-framework agl-demo-soundmanager
Bitbake agl-demo-platform-crosssdk
