build kernel_imx fail with "make O=../$(KERNEL_OUT)"

[xingruizhu]

Dear supporter

We want to redirect the kernel build output to $(TARGET_OUT_INTERMEDIATES)/KERNEL_OBJ

But the below error info occur:

add more info:

Another guy suffer the same issue:

http://boundarydevices.com/new-linux-kernels-for-i-mx6/

quote:

"

It doesn’t seem to be a problem with the source tree, bur rather the makefile rules.

The error only occurs if I build into a separate build tree using ‘make O=’

If I build directly in the Linux source tree, it works fine.

I’ll see if I can figure out why and propose a patch.

Hi Xingrui zhu,

Me too face similar Issue. Finally, I  have built my kernel @ out_dir with small tweak OR change mentioned as bellow...

Check if it works for you..

@ my  ./build_kernel.sh

---------------------------------------------------------------------------------------------------

# copy sdma-imx6q-to1.bin  to out directory before you compile kernel

cp --parents firmware/imx/sdma/sdma-imx6q-to1.bin $OUT_DIR/

make -j8 ARCH=arm imx6_android_defconfig O=$OUT_DIR

make uImage O=$OUT_DIR

---------------------------------------------------------------------------------------------------

Thanks,

Rajucm

Thank you.

It does work.
