Hi
After doing

make -j4 zImage 
make -j4 modules 
make -j4 dtbs 

I get error at this step do you have idea what could be the issue
make -j4 modules_install

I'm not a professional in this area, but based on the error message, it seems that the current user does not have permission to create a directory in the /boot folder. As a straightforward solution, I would suggest manually creating the directory using the bash command console or installing the binary file as the root user.
