'''TBD: rifare tutti i dump con le versioni corrette ''' '''TBD: eliminare eventuali sezioni non pertinenti (es. eMMC) per il SOC '''  === 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 to any DAVE Embedded Systems' Linux platform.

We'll explain how to program and configure a <SOM> to boot in standalone mode, without the need of a system microSD card or an NFS server, with threee 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* booting with NAND only** 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 eMMC flash === Program boot images into the Quad-SPI NOR flash ===

Update to the latest uFirst of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project#Petalinux_build | here]]. Alternatively you can download binaries from [https://mirror.dave.eu/desk-boot version allows usage of uxz-boot environment variables availablel/ mirror] and install it on microSD or into <code>tftpboot</code> directory in your host device.

* Format and initialize ''nand-ubi'' partition, which in our case This chapter is <code>mtd7</code>, using compatible with [[Memory Tecnology Device (MTD)#UBIBORA Lite SOM |UBIBORA Lite]] with:SOM.

First of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project| here]] with <precode>ubiformat config_boralite_nand_usd</devcode> configuration file, and install <code>wic</mtd7ubiattach code> binary on microSD. Then create artifact to install on NAND flash with <code>config_boralite_nand</code> configuration file, as described [[DESK-XZ7-m 7ubimkvol L/Development/devCreating_and_building_the_Petalinux_project| here]], and save the <code>BOOT.BIN</ubi0 code> and <code>dave-image-devel-N rootfs zynq-mgeneric.tar.gz</precode>artifact into the first partition of microSD.

EIn this case <code>BOOT.gBIN</code> binary that came from to <code>config_boralite_nand_usd</code> and <code>config_boralite_nand</code> are different, so save it with different name. Alternatively you can download binaries from [https://mirror.dave.eu/desk-xz-l/ mirror] and install on microSD.
