New page

== Linux BSP Version ==

We have two versions for rk3288 series.

'''V2.1 :'''

Debian 9 stretch Linux version 4.4.143

'''V230 :'''

Debian 10 buster Linux version 4.4.194

== Get Docker Image ==

If you don't have docker in your system, then you can follow the below  steps to install docker and run it first.

'''To install Docker Engine on your platform'''

Please refer to [https://docs.docker.com/engine/installation/ Docker Installation Guide] for details

'''To pull [https://hub.docker.com/r/advrisc/u16.04-rk3288lbv1/ ubuntu 16.04 image from Docker Hub] '''
<pre>$ sudo docker pull advrisc/u16.04-rk3288lbv1
$ sudo apt-get update
$ sudo apt-get install binfmt-support qemu-user-static</pre>

== Config Docker ==
<pre>$ mkdir -p ~/work/code/rk3288_debian
$ sudo docker run -it --name rk3288_linux --privileged -v ~/work/code/rk3288_debian:/home/adv/code:rw advrisc/u16.04-rk3288lbv1:latest /bin/bash
$ exit //This command run in dock workspace. It means exit dock workspace to host workspace.
</pre>

'''Note :''' 

The above commands only need run in the first time .

== Start Docker ==
<pre>$ sudo docker start rk3288_linux
$ sudo docker attach rk3288_linux</pre>

'''Note :''' 

After run the above two commands, you will work in docker workspace .

You can get debian source code and build them in docker workspace.

== Getting Debian Source Code ==

'''V2.1 :'''
<pre>$ cd ~/code
$ sudo git clone https://github.com/rockchip-linux/repo.git
$ mkdir rk3288_debian
$ cd rk3288_debian
$ git config --global user.name "Your Name"
$ git config --global user.email you@example.com
$ ../repo/repo init -u https://github.com/ADVANTECH-Rockchip/linux-manifest.git -b rk3288_linux_v2.0 -m default.xml
$ ../repo/repo sync
$ ../repo/repo forall -c git checkout -b local --track advantech-github/rk3288_linux_v2.0
$
$ sudo dpkg -i rootfs/ubuntu-build-service/packages/*
$ sudo apt-get install -f</pre>

'''V230 :'''
<pre>$ cd ~/code
$ sudo git clone https://github.com/rockchip-linux/repo.git
$ mkdir rk3288_debian
$ cd rk3288_debian
$ git config --global user.name "Your Name"
$ git config --global user.email you@example.com
$ ../repo/repo init -u https://github.com/ADVANTECH-Rockchip/linux-manifest.git -b rk3288_linux_v230_risc -m default.xml
$ ../repo/repo sync
$ ../repo/repo forall -c git checkout -b local --track advantech-github/rk3288_linux_v230_risc
$
$ sudo dpkg -i rootfs/ubuntu-build-service/packages/*
$ sudo apt-get install -f</pre>

== Build U-boot ==

=== Build RSB-4680 U-boot ===

'''V2.1  :'''
<pre>$ export TOP=`pwd`
$ cd $TOP
$ cd u-boot/
$ ./make.sh rsb4680a3-2G-rk3288

</pre>

'''V230 :'''
<pre>$ export TOP=`pwd`
$ cd $TOP
$ cd u-boot/
$ ./make.sh rk3288_rsb4680a3_2G

</pre>

== Build Kernel ==

=== Build RSB-4680 Kernel ===
<pre>$ cd $TOP
$ cd kernel/
$ make ARCH=arm rk3288_adv_defconfig
$ make ARCH=arm rk3288-rsb4680-a3.img -j12
</pre>

=== ===

== Build Recovery ==
<pre>$ cd $TOP
$ rm buildroot/output/rockchip_rk3288_recovery -rf
$ source envsetup.sh rockchip_rk3288_recovery
$ ./build.sh recovery
</pre>

'''NOTE：''' For recovery.img includes kernel and recovery tools， kernel MUST be built before recovery.

== Build Rootfs ==

'''V2.1 :'''
<pre>$ cd $TOP
$ cd rootfs/
$ sudo ARCH=armhf ./mk-rootfs.sh
$ sudo ARCH=armhf ./mk-adv.sh
$ sudo ./mk-image.sh</pre>

'''V230:'''
<pre>$ cd $TOP
$ sudo BUILD_IN_DOCKER=TRUE ./mk-debian.sh
</pre>

== Creating the ext4 image ==
<pre>$ cd $TOP
$ source envsetup.sh rockchip_rk3288_recovery
$ sudo ./mkfirmware.sh
</pre>

'''NOTE：''' If there is no error, the following ten files will be found in $TOP/rockdev/ : boot.img  MiniLoaderAll.bin  misc.img  oem.img  parameter.txt  recovery.img  rootfs.img  trust.img  uboot.img  userdata.img

== How to do about update RK3288 Platform? ==

There are two ways to update images : 

=== Android Tool ===

[[Update_image_through_AndroidTool_for_RK3288|Update image through AndroidTool]]

=== SD card ===

[[Update_image_through_SD-Card_for_RK3288|Update image through SD-Card]]

'''NOTE : '''

This way only support Linux(Debian9) upgrade to Linux(Debian9) 、 Android6.0 upgrade to Android6.0 or Android8.1 upgrade to Android8.1.

If the device is in Android, you want to upgrade to Linux(Debian9), please use Android Tool.

== User and password ==

Here are default user and password:

linaro 123456

root 123456

=== Build toolchain ===

To build a toolchain
<pre>$ cd ~/RSB4680_CODEBSAE/
$ source buildroot/build/envsetup.sh rockchip_rk3288
$ make
</pre>

The toolchain will be generated here
<pre>$ ~/RSB4680_CODEBSAE/
buildroot/output/rockchip_rk3288/host/arm-buildroot-linux-gnueabihf/
</pre>

== Initramfs ==

1). Get a sample inittamfs rootfs
<pre>$ git clone https://github.com/TeeFirefly/initrd.git </pre>

2). Make a cpio format gziped file
<pre>$ cd initrd
$ find . | cpio -o -H newc | gzip > ../initramfs_data.cpio.gz
</pre>

3). Copy "initramfs_data.cpio.gz" to ~/KERNEL_SRC/usr/

4). Add config CONFIG_INITRAMFS_SOURCE="usr/initramfs_data.cpio.gz" on rk3288_adv_defconfig

5). Rebuild boot image

If you'd like to modify initramfs rootfs
<pre>$ zcat initramfs_data.cpio.gz | cpio -i -d -H newc --no-absolute-filenames </pre>

You can point CONFIG_INITRAMFS_SOURCE to a folder directly also

1). Get a sample inittamfs rootfs
<pre>$ git clone https://github.com/TeeFirefly/initrd.git </pre>

2). CONFIG_INITRAMFS_SOURCE="../../initrd/"

3). Rebuild boot image

PS :

1). Find a init in the initramfs is not thing to do with kernel cmdline "root=".

2). This init inside the initrd.git will be triggered and boot the system completed. You may add anything you want to this rootfs.
