Populate eSDK
image build
MACHINE=turris source meta-turris/setup-environment
bitbake rdk-generic-broadband-image -c populate_sdk_ext
|
The generated eSDK installer resides under the directory build-<MACHINE>/tmp/deploy/sdk/rdk-glibc-x86_64-arm-toolchain-ext-2.0.sh of the Yocto workspace.
Note: The generated eSDK installer script usually occupies 1.5 to 2.5 GB
eSDK Installation
The installer can be done on any x86_64 Linux machines.
Host Configuration
Refer to the RDKCentral's credential configuration to setup RDK Central's credentials in the machine where eSDK to be installed. This is to access repositories by the RDK Yocto recipes that reside in the eSDK installer.
Installation
./rdk-glibc-x86_64-arm-toolchain-ext-2.0.sh

Build from eSDK
This section covers how to use the eSDK for component build and image build
Environment Setup
The installer can be run on any x86_64 Linux based machines.
cd ~/rdk_sdk
source environment-setup-armv7ahf-neon-rdk-linux-gnueabi
|
New Components
Add Component
Modify Component
devtool modify <recipe_name> <new URL>
|
Edit Component's recipe
devtool edit-recipe <recipe_name>
|
Build Components
devtool build <recipe_name>
|
Build Image
A complete RDK image can be generated from the eSDK installer.
Note: The same image where the eSDK populated can be generated here.
devtool build-image <IMAGE>
|
Note: Stabilized image is generated in Phase2
Known Issues
- Taskhash mismatch error may appear while generating image from sdk, but that would not break the build.
