Description HiFiBerry (Daniel) 2019-08-30 07:37:46 UTC 
When trying to build a Pi Zero W image with the latest release candidate, build stops when trying to install the DTB file for the Pi Zero:

>>>   Executing post-image script board/raspberrypi0w/post-image.sh

Makefile:84: recipe for target '_all' failed
make: *** [_all] Error 2

Seems to me that the filename should be bcm2708-rpi-0-w.dtb instead of bcm2708-rpi-zero-w.dtb

Commands to reproduce the error:

make raspberrypi0w_defconfig
make

Are you sure this is a clean build? I cannot reproduce it here:

INFO: vfat(boot.vfat): adding file 'bcm2708-rpi-0-w.dtb' as 'bcm2708-rpi-0-w.dtb' ...
INFO: vfat(boot.vfat): cmd: "MTOOLS_SKIP_CHECK=1 mcopy -bsp -i '/home/peko/source/buildroot/output-rpi/images/boot.vfat' '/home/peko/source/buildroot/output-rpi/images/bcm2708-rpi-0-w.dtb' '::'" (stderr):
INFO: vfat(boot.vfat): adding file 'rpi-firmware/bootcode.bin' as 'rpi-firmware/bootcode.bin' ...

And the file is there as it should be:

(In reply to info from comment #0)
But the defconfig USES bcm2708-rpi-0-w.dtb:

grep DTS_NAME configs/raspberrypi0w_defconfig                                                                                                                                                                                                                            
BR2_LINUX_KERNEL_INTREE_DTS_NAME="bcm2708-rpi-0-w"

Did you perhaps edit raspberrypi0w_defconfig locally?
Comment 3 HiFiBerry (Daniel) 2019-08-30 10:55:03 UTC 
Just did a fresh extract of the buildroot tar file. Works now. Looks like something was messed up on the system.
