Boot Image build Fail

[nishad_kamdar]

Hello All,

I followed the recently updated procedure to build the AOSP and Kernel from source.

Step 1: Download the AOSP source:

$ repo init -u https://android.googlesource.com/platform/manifest -b master
$ git clone https://github.com/96boards-hikey/android-manifest.git -b hikey970_v1.0 .repo/local_manifests
$ repo sync -j$(nproc) -c
$ source build/envsetup.sh
$ lunch hikey970-userdebug

Step 2: Build Kernel

1. Build ramdisk
2. copy ramdisk to tools folder
3. Modify the compilation script.
4. build kernel

While building the kernel, I get the following error:

  LD [M]  net/netfilter/xt_LOG.ko
  LD [M]  net/netfilter/xt_addrtype.ko
 Kernel Image build success! 
  CHK     scripts/mod/devicetable-offsets.h
  DTC     arch/arm64/boot/dts/hisilicon/kirin970-hikey970.dtb
 Hikey970 dtb build success! 
 Image-dtb build success! 
./build_kernel.sh: line 62: mkbootimg: command not found
 Boot Image build fail!

It seems that neither the Image.gz-dtb is being created nor the boot.img.

Can anyone please let me know where the problem might lie?

Thanks and regards,
Nishad

Thanks,

I used the same to build the images.
I found this post here as well to build the Image.gz-dtb.

No Image.gz-dtb after building kernel for Hikey970

I built Hikey970 kernel and then I expected to get Image.gz-dtb because Adnroid document for Hikey970 ( https://www.96boards.org/documentation/consumer/hikey/hikey970/build/aosp.md.html ) says “Copy the Image file (arch/arm64/boot/Image.gz-dtb) to the device/linaro/hikey-kernel directory as file: Image.gz-hikey970-4.9”. But I couldn’t find Image.gz-dtb only I can see Image.gz. Please let me know how to get Image.gz-dtb for Hikey970. I tried to use Image.gz for Image.gz-hikey970-4.9, built andr…
