Linux/AM5728: Android build issues

TSRDM

Part Number: AM5728

Tool/software: Linux

Can you forward the following questions in regards to the latest Android (building the source) issue that I am seeing on my setup.

I have loaded the latest PROCESSOR-SDK-ANDROID-AM57X 04_02_00_09 (http://software-dl.ti.com/processor-sdk-android/esd/AM57X/latest/index_FDS.html)

Build SDK reference: http://processors.wiki.ti.com/index.php/Processor_SDK_Android_Building_The_SDK

The issue I am having is that I have run into several build issues when building the AOSP (I can build linux and u-boot successfully)

Compile Error #1 - ninja: error: '/arch/arm/boot/zImage', needed by 'out/target/product/am57xevm/kernel', missing and no known rule to make it

Workaround: exported TARGET_PREBUILT_KERNEL to point to the local kernel build I built successfully.

Compile Error #2 –

ninja: error: '/drivers/scsi/scsi_mod.ko', needed by 'out/target/product/am57xevm/recovery.img', missing and no known rule to make it

11:51:39 ninja failed with: exit status 1

Is there something missing in the steps provided in the TI wiki to build the AOSP successfully?

Thank you!

Hello Dave,

I am looking into it. What version of Linux are you running on your computer?

Regards,
Nick

Anthony,

The reason you see the error is because we removed the prebuilt android kernel image, we rely on building android kernel image now.

Ref patch which started this : git.omapzoom.org/

If you are building Oreo (Proc SDK Android Dec Release)

Please ensure ,

Step-1:

Build Android Kernel ( zImage modules dtbs)

Step-2

goto android source dir

export KERNELDIR=<kernel_source_path>

. ./build/envsetup.sh

lunch full_am57xevm-userdebug

make -jX ( Number of threads based on your build machine).

Nick,

If these details are not documented in wiki , can you please update accordingly.

for compile error 2:

Ensure, when you are building android kernel , Build with command

make ARCH=arm CROSS_COMPILE=<path> zImage modules dtbs

As you can see, from device/ti/am57xevm.git BoardConfig.mk android now expects built modules .
