[HELP]building kernel for Xperia V by source kernel

Hello, I’m computer software engineer and right now I’m work on Android Kernel. I bought a Sony Cellphone (Xperia V) in order to perform my project.

a part of my project is about modifying kernel therefore I want to debug kernel again (for that device), According to that demand I went to your website( downloaded all of the files but in step 5 that said “make” your own device configuration (blue_tsubasa_defconfig) there isn’t specific file in GitHub:kernel-copyleft/arch/arm/configs/  so I don’t know how to continue?


and after that when I want to compile the specific kernel with 


~~> make ARCH=<arch> CROSS_COMPILE=$CROSS_COMPILE -j <cpu_thread_number>


this command run, between 600 or 700 CPU-thread-number and after that my linux(Ubuntu) log out and can't create kernel.



I really appreciate if you help me to succeed.

Re: [HELP]building kernel for Xperia V by source kernel


you have to fill the parameters with your config

ARCH=<arch> and -j <cpu_thread_number>

in the make command

make ARCH=<arch> CROSS_COMPILE=$CROSS_COMPILE -j <cpu_thread_number>



ARCH=arm and -j2
