| <h2>Description<a class="headerlink" href="#description" title="Permalink to this headline">¶</a></h2> |
| <p>This library accepts incoming image management commands from newtmgr and |
| acts on them.</p> |
| <p>Images can be uploaded, present images listed, and system can be told to |
| switch to another image.</p> |
| <p>Currently the package assumes that there are 2 image slots, one active |
| one and another one in standby. When new image is uploaded, it replaces |
| the one in standby slot. This is the model for scenario when MCU has |
| internal flash only, it executes the code from that flash, and there is |
| enough space to store 2 full images.</p> |
| <p>Image manager interacts with bootloader by telling it to boot to a |
| specific image. At the moment this has to be done by writing a file |
| which contains a version number of the image to boot. Note that image |
| manager itself does not replace the active image.</p> |
| <p>Image manager also can upload files to filesystem as well as download |
| them.</p> |
| <p>Note that commands accessing filesystems (next boot target, file |
| upload/download) will not be available unless project includes |
| filesystem implementation.</p> |
