Description David NewHamlet 2017-07-20 08:28:37 UTC

Compiling aarch64 kernel for raspberry pi 3 with following configure:

options         MD_ROOT
makeoptions     MFS_IMAGE=/usr/src/sys/arm64/conf/initrd.img

Throw error:

# --- embedfs_initrd.o --- 
# objcopy --input-target binary  --output-target   --binary-architecture aarch64  /usr/src/sys/arm64/conf/initrd.img embedfs_initrd.o
# objcopy: --binary-architecture: invalid target name
# *** [embedfs_initrd.o] Error code 1

As we can see, command 'objcopy' missed one arg after --output-target.
The correct command line should be 'objcopy --input-target binary  --output-target elf64-littleaarch64 --binary-architecture aarch64  /usr/src/sys/arm64/conf/initrd.img embedfs_initrd.o'.

This small patch will fix the issue. It works for me.
