Script accepts two parameters: 
    - build* 
        build catalog, it will accept any catalog with "build" in name
    default: ${BIN_DIR} is taken

    --gdb PARAM
        parameter to full gdb path, for gcc9 you can pass i.e.
        ~/gcc-arm-none-eabi-8-2019-q3-update/bin/arm-none-eabi-gdb-py
    default: gdb from your PATH

    --product PARAM
        product to run [PurePhone|BellHybrid]

examples:
./run.sh --product PurePhone  build-purephone-rt1051-RelWithDebInfo/ --gdb ~/gcc-arm-none-eabi-8-2019-q3-update/bin/arm-none-eabi-gdb-py // full specification
