| <p>You can enhance the functionality of your released embedded system by adding |
| ELF programs, which can be loaded from a file system. These programs can be |
| stored on an SD card or downloaded into on-board SPI FLASH, allowing for |
| easy updates or extensions to the system’s firmware.</p> |
| <p>There are two ways you can accomplish this:</p> |
| <section id="partially-linked"> |
| <h2>Partially linked<a class="headerlink" href="#partially-linked" title="Permalink to this heading"></a></h2> |
| <p>This describes building the partially linked, relocatable ELF program that |
| depends on a symbol table provided by the base firmware in FLASH.</p> |
| <p>Reference: |

| <h2>Fully linked<a class="headerlink" href="#fully-linked" title="Permalink to this heading"></a></h2> |
| <p>This describes building a fully linked, relocatable ELF program that does |
| not depend on any symbol table information.</p> |
