Broken build android 10 for imx8mini

[e_kotsarev]

Hello, I m trying to build android Q for imx8mm. I downloaded BSP package Q10.0.0_1.0.0_ANDROID_SOURCE and synced the sources. I should say, that OS is already set up and I have successfully built android 9 Pie. Lets see error:

jenkins@build:~/nxp/imx-android-10.0.0_1.0.0/android_build$ make bootimage -j33

Hello Евгений,

the documentation has an explanation (Android_User's_Guide.pdf ):

The original purpose of this "imx-make.sh" is to build U-Boot/kernel before building Android images.
Google started to put a limit on the host tools used when compiling Android code from Android10.0. Some host tools necessary for building U-Boot/kernel now cannot be used in the Android build system, which is under the control of soong_ui, so U-Boot/kernel cannot be built together with Android images. Google also recommends to use prebuilt binaries for U-Boot/kernel in Android build system. It takes some steps to build U-Boot/kernel to binaries and put these binaries in proper directories, so some specific Android images depending on these binaries can be built without error. "imx-make.sh" is then added to do these steps to simplify the build work. After U-Boot/kernel are compiled, any build commands in standard Android can be used.

It is a natural fact that things change in our line of work.  Actually It is more susprising for me when things don't change :smileyhappy:

Hi Евгений,

the error says that the Linux kernel has not been compiled.  The documentation says that there is a shell script "${MY_ANDROID}/imx-make.sh" that should be run first to compile U-Boot/Kernel before compiling Android.  Did the script execute without errors?

Thank you, indeed, despite of Pie version building fine without any proprietary scripts. Just execute make bootimage | make | make systemimage | make whatever and it's fine as we get used to in AOSP| LineageOS | ALPS | etc

But in Q version I should execute ${MY_ANDROID}/imx-make.sh kernel before make bootimage. It's a little bit strange, isn't it?
