| <p><strong>Q</strong>: 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?</p> |
| <p><strong>A</strong>: Elfs have a lot of extra information. newt size will show the are in flash that is used which better matches the |
| <code class="docutils literal notranslate"><span class="pre">blinky.elf.bin</span></code> file. Try <code class="docutils literal notranslate"><span class="pre">running</span> <span class="pre">newt</span> <span class="pre">-ldebug</span> <span class="pre">build</span> <span class="pre">-v</span> <span class="pre"><your-target></span></code> and you will see something like this:</p> |
