Build Android 9 boot.img problem

[yenchou]

Hi All,

When I used  imx-p9.0.0_2.2.0-ga to build boot.img, I met a problem.

I used google and other community, but did not find a solution.

The build log:

Did anyone meet the same problem?

How do I resolve the err?

Thank you for your help.

Hi Yen Chou,

No, you don't need to do the step $make clean every time.

Hi Yen Chou ,

Can you please try to build boot.img after clean it with $make clean. We are able to build boot.img with the steps provided in your comment.

Hi Radhika,

Sorry for reply late, I took leave last Friday.

I  used clean with  $make clean then it built  successfully.

Do I have to do the step "$make clean"  before I build boot.img every time?

Many thanks,

Yen Chou.

Hi Yen Chou,

It seems like you are building for i.MX 6Quad/6DualLite/6QuadPlus SABRE-AI Board. You can refer Table 1. Build names from Android User's Guide for android device name.

Please try once to build with the below steps:

         $ cd ${MY_ANDROID}

         $ source build/envsetup.sh
         $ lunch sabreauto_6q-userdebug
         $ make bootimage

Hi Radhika,

Thank you for your quick reply.

Sorry, I copied the wrong words, the correct words is "lunch sabresd_6dq-userdebug".

I want to build  image for imx6 DualLite SABRE-SD board.

Now I have to copy .config and zconf.lex.c files to out/target/product/sabresd_6dq/obj/KERNEL_OBJ.

But I think the method is not regular, I have to find other method.

Many thanks,

Yen Chou.

Hi Yen Chou ,

We are able to build boot.img with imx-p9.0.0_2.2.0-ga for i.MX 6Quad/6DualLite/6QuadPlus SABRE-SD Board and SABRE Platform. To build boot.img you can refer section 3.5 Building boot.img from the attached Android User's Guide. You can download the documents from the below link.

https://www.nxp.com/docs/en/supporting-information/android_p9.0.0_2.2.0-ga_docs.zip 

Can you please share the build steps which you have followed? 

Regards,

Radhika Somaiya.

Hi Radhika,

Thank you for your reply.

I already read the documents before build Android9 and followed the documents steps to do.

My steps is

$ export MY_ANDROID=~/android_build

$ cd ${MY_ANDROID}
$ source build/envsetup.sh
$ lunch sabreauto_6dq-userdebug
$ make bootloader -j4

$ cd ${MY_ANDROID}/vendor/nxp-opensource/kernel_imx

$ export ARCH=arm
$ export CROSS_COMPILE=${MY_ANDROID}/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androideabi-

$ make imx_v7_android_defconfig

$ make KCFLAGS=-mno-android

$ cd ${MY_ANDROID}

$ make bootimage

When I used the command "make bootimage", the error happened.

I found the path "android_build/out/target/product/sabresd_6dq/obj/KERNEL_OBJ" didn't have .config file, then I 

found other path "android_build/out/target/product/sabresd_6dq/obj/KERNEL_OBJ/scripts/kconfig/" also didn't have zconf.lex.c file.

But I didn't know what happend.

Do you have any ideas?
