6.3 Setup Network Configurations

By default "eth0" is assigned an IP address obtained via dhcp. If you want to change the setting you need to change the following file:

vi /etc/network/interfaces.d/eth0

For example if you want to assign a static IP to it you can run the following commands:

auto eth0
iface eth0 inet static
    address 192.168.1.231
    netmask 255.255.255.0
    gateway 192.168.1.1

To change the setting of "eth1" you can add a new file similar to eth0's configuration file under the /etc/network/interfaces.d/ directory.

cd sd-fuse_rk3399
wget http://112.124.9.243/dvdfiles/RK3399/images-for-eflasher/friendlycore-focal-arm64-images.tgz
tar xvzf friendlycore-focal-arm64-images.tgz

8.3.2 Compile the kernel

Download the kernel source code and compile it. the relevant image files in the friendlycore-focal-arm64 directory will be automatically updated, including the kernel modules in the file system:

git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-v4.19.y kernel-rk3399
KERNEL_SRC=$PWDkernel-rk3399 ./build-kernel.sh friendlycore-focal-arm64

8.3.3 Compile the uboot

Download the uboot source code and compile it. the relevant image files in the friendlycore-focal-arm64 directory will be automatically updated:

git clone https://github.com/friendlyarm/rkbin
(cd rkbin && git reset 25de1a8bffb1e971f1a69d1aa4bc4f9e3d352ea3 --hard)
git clone https://github.com/friendlyarm/uboot-rockchip --depth 1 -b nanopi4-v2017.09
UBOOT_SRC=$PWD/uboot-rockchip ./build-uboot.sh friendlycore-focal-arm64

8.3.4 Generate new firmware

Repackage the image file in the friendlycore-focal-arm64 directory into sd card firmware:

./mk-sd-image.sh friendlycore-focal-arm64

After the command is completed, the firmware is in the out directory, you can use the dd command to make the SD boot card, for example:

dd if=out/rk3399-sd-friendlycore-focal-4.19-arm64-YYYYMMDD.img of=/dev/sdX bs=1M

8.4 Compile kernel and uboot for FriendlyCore-Focal OS in normal way

8.4.1 Compile FriendlyCore-Focal's Kernel-4.19 Source Code

git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-v4.19.y kernel-rockchip
cd kernel-rockchip
make distclean
touch .scmversion
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH
make ARCH=arm64 CROSS_COMPILE=aarch64-linux- nanopi4_linux_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux- nanopi4-images

After compilation is done a kernel.img and a resource.img will be generated.

8.4.2 Compile FriendlyCore-Focal's uboot-2017.09 Source Code
