Linux kernel 4.12 branch

xlazom00 · June 30, 2017, 1:49pm

You will need latest bootloader from
‘’'https://github.com/96boards-hikey/tools-images-hikey960
run recovery-flash.sh to update bootloader

and one 4.12 kernel
‘’'https://github.com/96boards-hikey/linux/tree/hikey960-upstream-rebase
branch “hikey960-upstream-rebase”

then
export DTB=hi3660-hikey960.dtb
export ARCH=arm64
export BOOT=arch/arm64/boot
export CROSS_COMPILE=aarch64-linux-gnu-
export OUT=out_v8
export RAMDISK=/home/misko/image_out/ramdisk.gz
mkdir out_v8
make defconfig O=$OUT
if you want to enable/disable some drivers in my case usb network adapter
make menuconfig O=$OUT
make ${UIMAGE} -j8 O=$OUT

make boot.img

and dt.img

root@linaro-developer:~# uname -a
Linux linaro-developer 4.13.0-rc6-linaro-hikey960 #1 SMP PREEMPT Tue Sep 5 09:20:37 EDT 2017 aarch64 GNU/Linux

I also installed the kernel modules into /lib/modules/ .

Can you post here all the steps to get this kernel into the Hikey board ?
Which version of the UEFI did you used ?

domi · September 8, 2017, 1:08pm

This is without UEFI .
