==Standalone boot==
 
=== 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 to any DAVE Embedded Systems' Linux platform.
** in this configuration the primary boot images and rootfs will be fetched from NAND flash storage
=== Program boot images into internal storage ======= Program the Quad-SPI NOR flash ====
This chapter is compatible with ''Bora''[[BORA SOM | BORA]], ''Boralite'' [[BORA Xpress SOM | BORA Xpress]] and ''BoraX'' [[BORA Lite SOM | BORA Lite]] platforms, but below there is log for ''BoraX'' platformBORA Xpress SOM.
First 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-xz-l/ mirror] and install it on microSD or into <code>tftpboot</code> directory in your host device.

==== Program the NAND flash ==== This chapter is compatible with [[BORA Lite SOM | BORA Lite]] SOM.
This chapter is compatible First of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project| here]] with ''Boralite'' platform<code>config_boralite_nand_usd</code> configuration file, and install <code>wic</code> binary on microSD. Then create artifact to install on NAND flash with <code>config_boralite_nand</code> configuration file, as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project| here]], and save the <code>BOOT.BIN</code> and <code>dave-image-devel-zynq-generic.tar.gz</code> artifact into the first partition of microSD.

In this case <code>BOOT.BIN</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.
In this case Then, install the following files into the microSD first partition of microSD you need to install the following file:
* <code>BOOT.BIN</code>. This binary come from to <code>config_boralite_nand_usd</code> configuration file, and need to install on uSDmicroSD
* <code>boot.scr</code>
* <code>desk-xz7-l-1.0.1_boralite_nand_BOOT.BIN.EXTENDED</code>. This binary come from to <code>config_boralite_nand</code> configuration file, and need has to install be installed on NAND flash
* <code>desk-xz7-l-1.0.1_boralite_nand_dave-image-devel-zynq-generic.tar.gz</code>
* <code>image.ub</code>
