Repository for rockchip yocto SDK

Yocto SDK for the Rockchip SOC boards

• wiki http://opensource.rock-chips.com/wiki_Main_Page.

Quick Start

1. Get the code using the Manifest and Repo tool:
   https://source.android.com/setup/develop/repo
2. Config your local config file (build/conf/local.conf)
   • You can create a local.conf manually, follow:
   • https://git.yoctoproject.org/cgit.cgi/poky/plain/meta-poky/conf/local.conf.sample
   • Or use the existing config files for demoing e.g.: rockchip-rk3326-evb.conf
3. Run "source ./oe-init-build-env" to setup bitbake environment
4. Run "bitbake core-image-minimal" to build the images
5. Flash the generated "build/tmp/deploy/<MACHINE>/update.img" to your device
6. Boot your device and enjoy it

Example: Build ROCK 5B Machine

Get source code

$ mkdir ~/yocto-rockchip-sdk && cd ~/yocto-rockchip-sdk
$ repo init -u https://github.com/radxa/yocto-manifests.git -b scarthgap
$ repo sync

Link the local.conf to the target board configuration file. Here we aim to build ROCK 5B machine, so the local.conf is linked to rockchip-rk3588-rock-5b.conf. You should change the link when you build the other machine.

$ cd ~/yocto-rockchip-sdk/build/conf
$ ln -sf rockchip-rk3588-rock-5b.conf local.conf
$ ls -al local.conf
lrwxrwxrwx 1 radxa radxa 28 Nov 21 14:44 local.conf -> rockchip-rk3588-rock-5b.conf

Start build

$ cd ~/yocto-rockchip-sdk
$ source ./oe-init-build-env
$ bitbake core-image-minimal

And you will get the target system image under build/tmp/deploy/images/rockchip-rk3588-rock-5b/.

There are two formats of system images. One is wic, core-image-minimal-rockchip-rk3588-rock-5b.rootfs.wic. And the othe one is rkupdate, core-image-minimal-rockchip-rk3588-rock-5b.rootfs.update.img.

Write the image

For eMMC

Choose image core-image-minimal-rockchip-rk3588-rock-5b.rootfs.wic. Choose one of the following flash ways:

• Install the system on the EMMC Module
• RKDevTool
• rkdeveloptool

For MicroSD Card

Choose image core-image-minimal-rockchip-rk3588-rock-5b.rootfs.update.img. You can refer to this guide, Write the image to MicroSD Card with SDDiskTool.
