Embedded module TQMaRZG2x - YOCTO Linux BSP documentation

• BSP built according to quickstart guide
• Built Yocto SDK based on the current RootFS configuration, installed on the development host. See Build Yocto SDK how to build it.
• Configured SSH login on target. See setup ssh connection
• Configured Network connection to the development host

The following has to be added to the local.conf file in the build directory or to your custom image recipe:

EXTRA_IMAGE_FEATURES = " eclipse-debug"
IMAGE_INSTALL_append = " openssh-sftp-server" 

This guide uses a password based authentication for the ssh target connection. The password can be setup with the passwd command on the target. The password can also be defined in the local.conf file or your custom image recipe. Below you will find a an example to add the password password to the user root.

INHERIT += "extrausers"
EXTRA_USERS_PARAMS = "usermod -P password  root;"

The Eclipse IDE requires the following packages installed on the development host:

• build-essential
• gdb
• gdb-multiarch
• git
• default-jre

On a Ubuntu based development host, they can be installed by the following commands:

sudo apt-get install build-essential gdb gdb-multiarch git default-jre
