Build friendlycore bootable SD card

git clone https://github.com/friendlyarm/sd-fuse_rk3328.git
cd sd-fuse_rk3328
sudo ./fusing.sh /dev/sdX friendlycore-arm64

You can build the following OS: friendlycore-arm64, friendlydesktop-arm64, lubuntu, eflasher.
Because the android system has to run on the emmc, so you need to make eflasher img to install Android.

Notes:
fusing.sh will check the local directory for a directory with the same name as OS, if it does not exist fusing.sh will go to download it from network.
So you can download from the netdisk in advance, on netdisk, the images files are stored in a directory called images-for-eflasher, for example:

cd sd-fuse_rk3328
tar xvzf ../images-for-eflasher/friendlycore-arm64-images.tgz
sudo ./fusing.sh /dev/sdX friendlycore-arm64

Build an sd card image

First, download and unpack:

git clone https://github.com/friendlyarm/sd-fuse_rk3328.git
cd sd-fuse_rk3328
wget http://112.124.9.243/dvdfiles/RK3328/images-for-eflasher/friendlycore-arm64-images.tgz
tar xvzf friendlycore-arm64-images.tgz

Now, Change something under the friendlycore-arm64 directory, for example, replace the file you compiled, then build friendlycore-arm64 bootable SD card:

sudo ./fusing.sh /dev/sdX friendlycore-arm64

or build an sd card image:

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

The following file will be generated:

out/rk3328-sd-friendlycore-bionic-4.4-arm64-yyyymmdd.img

You can use dd to burn this file into an sd card:

dd if=out/rk3328-sd-friendlycore-bionic-4.4-arm64-20181112.img of=/dev/sdX bs=1M
