I want to be able to build the linux kernel for my LS2080A RDB manually from within the Yocto project.
Following the Freescale Yocto Project Quick Start Guide, if I do
bitbake -c cleansstate virtual/kernel
bitbake -c compile virtual/kernel
I get a directory tmp/work-shared/ls2080ardb/kernel-source which is filled with all the kernel source code, a Makefile and so on.
Within the kernel-source directory, normal kernel compilation would allow something like
make ARCH=arm64 CROSS-COMPILE=/path/to/cross/compiler/aarch64-fsl-linux- vmlinux
but this gives errors when I run it.
Can anyone point to how I can build the kernel manually? Better still, how can I build the kernel completely outside the Yocto project?
