Introduction
This document was written and tested with the software/hardware combination described in the history table above. However, it contains general concepts that can be adapted on any DAVE Embedded Systems' Linux platform.
{{ImportantMessage|text=The following programming examples are intended for <b>laboratory usage</b> or for ''preliminary deployment strategy''.<br><br>A complete deployment strategy has to be carefully identifiyed identified taking into account the overall arguments like: boot speed, safe boot, recovery mechanisms, watchdog supervisor, etc.}}
We'll explain how Generally speaking, it is possible to program and configure a <SOM> to boot in standalone mode, without the need of a system microSD card or an NFS server, for example, with threee three options:
* booting with NOR and NAND internal storage
** in this configuration the primary boot images will be fetched from NOR flash storage, while the root file system will be fetched from NAND flash
** in this configuration the whole system will boot without the need of a NOR flash storage, all images and the root file system will be fetched from NAND flash
* booting with eMMC only
** in this configuration the whole system will boot without the need of a NOR/NAND flashes storage, all images and the root file system will be fetched from the eMMC flash
{{ImportantMessage|text=In the following paragraphs, we will take into account a real case using an embedded eMMC mounted in the [[ORCA SOM | ORCA]] or [[MITO 8M Mini SOM |MITO 8M Mini]] SOMs}}
