Kernel build is failing for arpi-5.10

[mse6cob]

@peyo-hd :

I got the below error while building the kernel with arpi-5.10.

$ build/build.sh
build/build.sh: line 424: nproc: command not found
build/build.sh: line 425: readlink: command not found
build/build.sh: line 426: readlink: command not found
build/build.sh: line 427: readlink: command not found
build/build.sh: line 472: rm: command not found

Because of that, I followed the below commands for building the kernel arpi-5.10.

$ cd common
$ ARCH=arm64 scripts/kconfig/merge_config.sh arch/arm64/configs/bcm2711_defconfig kernel/configs/android-base.config kernel/configs/android-recommended.config kernel/configs/android-recommended-arm64.config kernel/configs/android-base-conditional.config
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make Image.gz
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- DTC_FLAGS="-@" make broadcom/bcm2711-rpi-4-b.dtb
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- DTC_FLAGS="-@" make overlays/vc4-kms-v3d-pi4.dtbo
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- DTC_FLAGS="-@" make broadcom/bcm2711-rpi-400.dtb

Build was successful.

Could you please let me know whether it is correct.

Thanks

Hi @mse6cob ,

You can try this:
under the build folder and use git command: git reset --hard f8ae8a9be8b018ba90a0f576488833fabb3fda74

also make sure you don't have these files or directories:

1. $(srctree)/.config
2. $(srctree)/include/config
3. $(srctree)/arch/$(SRCARCH)/include/generated

To avoid this issue, put the kernel source under aosp tree :
source build/envsetup.sh
lunch 66
.cd android-kernel/
./build/build.sh

Hi @mse6cob,
I experienced the same issue and was able to work around it by using the following command:
HERMETIC_TOOLCHAIN=0 build/build.sh
That way you can build in a separate directory outside the AOSP tree.
Also see my pull request that fixes an issue with the prebuilt toolchain.

After checking PR of @icedieler ,
Rebased arpi-5.10 to common-android12-5.10-lts.
You can check if build works with this change.

Hi @peyo-hd ,

Thanks for the input. I have re based again with latest arpi-5.10.
But still i facing the below error.

merged configuration written to android_kernel/common/arch/arm64/configs/arpi_defconfig (needs make)

set +x
cd common
make LLVM=1 LLVM_IAS=1 DEPMOD=depmod DTC=dtc O=android_kernel/out/arpi-5.10/common arpi_defconfig

So I have tried with (https://github.com/MaJiu/kernel_manifest) . Build is successful.

Thanks.

Hi @peyo-hd @icedieler ,

I am able to run android 12 on Raspberry Pi4.

But NOT able to connect adb over USB..

Could you please let me know the steps for connect adb over USB.

Thanks.

[icedieler]

Hi,
unfortunately that is not possible because the USB ports on the Raspberry Pi 4 do not support device mode. You can use ADB via network though.

[mse6cob]

Hi @icedieler,

We are not able to navigate through Developer options while selecting is redirected to Home screen.
Could you share the steps to enable ADB via network without using USB.

Thanks.

[icedieler]

Hi @mse6cob ,
what kind of Android build do you have? If it is an engineering build then adbd is started by default. You don't need to do anything on the device. Just plugin an ethernet cable and from your host you can connect via adb connect <ip addr> && adb shell

[mse6cob]

Hi @icedieler ,

I am building the android source using the below repository. I think it is an engineering build.

https://github.com/android-rpi/local_manifests

Android12 build is successful and it is up and running . But I am not able to get the ip address of the Pi4.

Please find the ifconfig output of Pi4.

console:/ $ ifconfig

If I set the IPAddress, "Operation not permitted" message is seen in console.

Could you please let me know how to set the IPAddress.

Note: Also I have tried another variant of android 12(omnirom) using the below repository. In this I am able to connect adb over USB.

https://github.com/omnirom/android_device_brcm_rpi4

Thanks.

[icedieler]

Yes, you cannot manually configure an IP address as a non-privileged user. The easiest thing would be to have a DHCP server on your network that just assigns an IP address to your Pi. Alternatively you can achieve that with manual ip commands setting the IP address, gateway etc. in a custom init.rc.

[mse6cob]

Hi @icedieler @peyo-hd,

I have checked the services which are running in Pi board.

DHCP service is NOT running

Could you share the steps of manual ip setting in init.rc file.

Thanks.
