Where is kirin970-hikey970.dtb?

Build doc says it is in arch/arm64/boot/dts/hisilicon/ kirin970-hikey970.dtb but it is not there after cloning. It is also not in 96boards-hikey970 git repo online.

Which build doc? (always better to put a link into questions like this)

It saying,

Copy Pre-Built Kernel Binaries

  • Copy kirin970-hikey970.dtb.dtb (arch/arm64/boot/dts/hisilicon/ kirin970-hikey970.dtb) to the device/linaro/hikey-kernel directory as file: kirin970-hikey970.dtb-4.9

Where can I find it???

I don’t think hikey970 repos contain pre-built kernel binaries so what this section really means is how to copy a self-built kernel into where the AOSP build system expects to find it (put another way, AOSP does not build the kernel itself… it assumes that it is pre-built before compiling AOSP).

It looks to me like the instructions on the web site were originally a single document and they have been split appart with hyperlinking them together properly. I have filed a bug about this:

For now the instructions to build the kernel yourself are found in the other document:

Right. Something is wrong on the documents.
I generate it using this build step.

  1. Download kernel from git ( git clone https://github.com/96boards-hikey/linux.git )
  2. build kernel and use it. When I need to use ramdisk.img, I get it from http://hihope.org/resource/hikey970_android_8_images.rar )
  3. Build Android

But for my case, I failed to use built android when I used it with master branch. I think something still missing. I don’t know which android version I should use to build. I didn’t feel Hikey’s software support is good.

When building kernel images the dtb can be built manually using:

make dtbs

that will create the dtb file arch/arm64/boot/dts/hisilicon/kirin970-hikey970.dtb

Hope that answers the question

Thank you all.
But we all stll wating perfect & verified build guild from “96boards.org”. Isn’t it?
They still no answer and no fix.

the dtb files will not be part of the github repository since they can be generated using ‘make dtbs’
The guthub repository is for sources and not for precompiled binaries

I have updated the instructions Build AOSP on HiKey970 - 96Boards

take a look now

I followed the instructions:

$ mkdir <ANDROID_TOP>
$ 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

But when I try to make ramdisk:

$ make -j$(nproc) ramdisk

I get the following error:

[ 29% 114/389] including device/linaro/hikey/Android.mk ...

#### failed to build some targets (20 seconds) ####

i have fixe this error by replacing eng by optional in device/linaro/hikey/Android.mk

But now i get the following errors
