| ``newt size`` Command vs. Elf File Size |
| --------------------------------------- |
| |
| **Q**: I did a test build of blinky for nrf52 and got an elf-file of size 295424 bytes. If I use the newt size command for |
| the application it says something like: 18764 bytes. What does this mean? |
| |
| **A**: Elfs have a lot of extra information. newt size will show the are in flash that is used which better matches the |
| ``blinky.elf.bin`` file. Try ``running newt -ldebug build -v <your-target>`` and you will see something like this: |
| |
| .. code-block:: console |
| |
| arm-none-eabi-objcopy -R .bss -R .bss.core -R .bss.core.nz -O binary ... |
