SSH, or Secure Shell, is a cryptographic network protocol used with client-server architecture for securely accessing and managing devices remotely. In the context of the Yocto Project and OpenEmbedded, SSH allows developers to interact with their embedded systems efficiently. To include SSH functionality in your Yocto-built image, you can add an SSH server by modifying the conf/local.conf file. Specifically, add the following line to the end of the file: EXTRA_IMAGE_FEATURES:append = " ssh-server-dropbear". This configuration ensures that the Dropbear SSH server is included in your image. To verify that EXTRA_IMAGE_FEATURES is correctly set, you can use the bitbake-getvar command. For example, running bitbake-getvar EXTRA_IMAGE_FEATURES will display its current value, helping you confirm that "ssh-server-dropbear" has been successfully added. The video demonstrates SSH on Raspberry Pi 5 with core-image-base built with the Yocto Project LTS release Scarthgap. Follow these steps to enable SSH as shown in the video:
* Enter the directory where core-image-base was built following the steps from episode 1.
* Initialize the build environment:
source oe-init-build-env
* Append the following line to the end of conf/local.conf:
EXTRA_IMAGE_FEATURES:append = " ssh-server-dropbear"
* Verify that the value of variable EXTRA_IMAGE_FEATURES contains ssh-server-dropbear:
bitbake-getvar EXTRA_IMAGE_FEATURES
* Build the image:
bitbake core-image-base
