To enable the ECall service, run either of the following commands to compile the TelAF
            simulation image under the TelAF root directory.

    # In Dev PC Host
    make simulac IMPORT_SDK_SIMULATION=y sdk_rootfs=<path/to/your/generated/rootfs> TELAF_SIMULATION_ENABLE_ECALL=yCopy to clipboard

    # In Dev Container
    cat >> simulation/.simulation.build << EOF
    export IMPORT_SDK_SIMULATION = y
    export sdk_rootfs=/path/to/your/generated/rootfs
    export TELAF_SIMULATION_ENABLE_ECALL = y
    EOF
    
    echo "make simula-c" > simulation/workstation/.simula.dev.action.sh
    make simula-xCopy to clipboard
