Hi Thomas,
Thanks for your reply.
I'm working on a beagle bone black wireless board with a custom config
based on "beaglebone_defconfig".
Indeed, I was not able to reproduce it from the buildroot directory also...
It seems the problem comes only when I build outside of it.
To avoid changing something in the buildroot tree and make it easier to
update it later, I made a wrapper script that change to buildroot dir and
use all the configs/packages/... a directory level below it.
A short example:
root-project
|- buildroot/
| |- arch/
| |- configs/
| |- ...
|- output/
|- beaglebone_defconfig
|- uboot.fragment
....
So, to reproduce that problem, I did the following:
mkdir test && cd test
git clone git://git.buildroot.net/buildroot.git buildroot
cd buildroot && git checkout 2018.05-1 && cd ..
make -C buildroot O=$PWD/output defconfig
BR2_DEFCONFIG=../beaglebone_defconfig
make -C buildroot O=$PWD/output menuconfig
changed:
BR2_TARGET_UBOOT_BOARD_DEFCONFIG="am335x_boneblack"
BR2_TARGET_UBOOT_CONFIG_FRAGMENT_FILES="../uboot.fragment"
uboot.fragment:
CONFIG_MULTI_DTB_FIT=y
CONFIG_OF_LIST="am335x-boneblack"
make -C buildroot O=$PWD/output uboot
make: Entering directory '/home/ddg/test/buildroot'
/usr/bin/make -j1 O=/home/ddg/test/output HOSTCC="/usr/lib64/ccache/gcc"
HOSTCXX="/usr/lib64/ccache/g++" silentoldconfig

If I remove the uboot.fragment, all is building well up to the end.
Moreover, why do he use ./scripts/dtc/dtc ? It should use
$(HOST_DIR)/bin/dtc at the moment host-dtc is build, no ?
Regards,
David
