Hikey970 Android won't boot


#1

I built boot.img as described on https://www.96boards.org/documentation/consumer/hikey/hikey970/build/linux-kernel.md.html.
But boot fail due to calling init failure.

I checked if there was init file. It was.

Android booting issue with hikey960 board using tools-images-hikey960/build-from-source/README-build-from-source.md

I think this is the same kind of issue as the one on dragonboard (Bootloop in db410c for Linaro AOSP using custom Kernel).

init is unable to find partition table to mount system part, which is supposed to be defined in the device-tree.
I found this patch for hikey960: https://android.googlesource.com/kernel/hikey-linaro/+/984ec0cd1188833c8ccac36c888a7524f916284e^!/#F0
but nothing for Hikey970.

Could you try to apply the same kind of change in hike970 dts and let me know.

Thank you very much for your help, Loic. Let me try it.


#4

After using ramdisk.img from official release http://hihope.org/resource/hikey970_android_8_images.rar , this booting problem fixed without any changes on dts file for Hikey970.

Previously, I had used ramdisk.img by building android instructed on https://www.96boards.org/documentation/consumer/hikey/hikey970/build/aosp.md.html.

I hope that official document for Hikey970/960 provide exact information.

Thanks again for your help Loic.
