Hi, The board imx53 board which we are having is imx53 QSB(Quick Start Board) Board in which cpu core is of cortex-A8.

While trying to compile linaro4.3 SDK for imx53QSB using below command,throws an error : command: make TARGET_TOOLS_PREFIX=prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8-linaro/bin/arm-linux-androideabi- TARGET_PRODUCT=imx53 systemtarball userdatatarball boottarball

Error: ============================================ bionic/libc/Android.mk:425: TARGET_CPU_VARIANT is not defined bionic/libc/arch-arm/arm.mk:32: *** "TARGET_CPU_VARIANT not set or set to an unknown value. Possible values are cortex-a9, cortex-a15, krait. Use generic for devices that do not have a CPU similar to any of the supported cpu variants.". Stop. ============================================

Later added TARGET_CPU_VARIANT variable as cortex-a8 in in device/linaro/iMX53/BoardConfig.mk file.

But cortex-a8 folder is not there in "bionic/libc/arch-arm/ " path. so Error is still there, ================================= bionic/libc/arch-arm/arm.mk:32: *** "TARGET_CPU_VARIANT not set or set to an unknown value. Possible values are cortex-a9, cortex-a15, krait. Use generic for devices that do not have a CPU similar to any of the supported cpu variants.". Stop. ==================================

Please help us what we have to do next ,how to resolve above error?

Thanks & Regards, Sowmya

Hi, don't use generic-eng.

Try skipping lunch altogether and using

make TARGET_TOOLS_PREFIX=prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8-linaro/bin/arm-linux-androideabi- TARGET_PRODUCT=imx53 systemtarball userdatatarball boottarball

That's what we used for the last working builds (minus the 4.8 part, 4.8 is a lot newer than the last imx53 build).

Hi, We just added TARGET_CPU_VARIANT:= generic in device /linaro/iMX53/BoardConfig.mk file. Then we got error saying no uboot diectory, as of now uboot was not required as we already have uboot image for imx53. So commented below line in "device/linaro/common/tasks/kernel.mk" file #BOOTLOADER_DEP := $(PRODUCT_OUT)/u-boot.bin

So JellyBean 4.3 code got compiled successfully for imx53 with no other errors, But Out target(out/target/product/imx53) directory doesn't contain "userdata.tar.bz2 ,system.tar.bz2, boot.tar.bz2 " any of these tarball .

Command used for compilation:

make -j4 TARGET_TOOLS_PREFIX=prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8-linaro/bin/arm-linux-androideabi- TARGET_PRODUCT=iMX53 systemtarball userdatatarball boottarball

I've just committed a (completely untested) fix for this. http://review.android.git.linaro.org/#/c/4342/

Later added TARGET_CPU_VARIANT variable as cortex-a8 in in device/linaro/iMX53/BoardConfig.mk file.

But cortex-a8 folder is not there in "bionic/libc/arch-arm/ " path.

There is no support for cortex-a8 in 4.3 (no current device uses A8 anymore), and 4.2 didn't have CPU specific optimization bits. So the correct variant for cortex-a8 in 4.3 (unless you want to go an extra step and push optimized functions for A8) is "generic".

I've pushed a patch that should fix this, but it is completely untested, while it should fix this problem, you might run into another one. If you want to be on the safe side, try building the 4.2 branch (that has been done successfully before - nobody else has tried building 4.3 for imx53 before).
