I think the correct location is under /lib folder. That is the toolchain issue. BASELIB has to be set to 'lib64', so ld-linux-aarch64.so.1 is installed to /lib instead of /lib64.

Hello,

Hi Adrian,

Sorry for late answer. I though you will begin work few hours later.

   Building a core-image-minial with poky distro for a new aarch64 machine I found that the ld-linux-aarch64.so is stored under /lib64 folder into rootfs.
   Due to this issue the init process doesn't start. I think the correct location is under /lib folder.

That is the toolchain issue. BASELIB has to be set to 'lib64', so ld-linux-aarch64.so.1 is installed to /lib instead of /lib64. Please try patch attached that I redefined the dynamic linker position.

Regards,
Kai


Kernel panic - not syncing: No working init found.  Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

   Is there any configuration that need to be done or patch for this issue?

Thank you in advance,
Adrian
