Hi I'm getting the below error
the file they mention with fatal error is definatly missing.

I see there is a make file called makefile.dtbinst in the build_dir scripts folder is this the file that creates/copys the dtb file into the target directory?

rm -f /home/professor_jonny/openwrt/build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-ipq40xx_generic/glinet_gl-b1300-fit-uImage.itb
