We'll explain how to program and configure a <SOM> to boot in standalone mode, without the need for a system microSD card or an NFS server, with 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* booting with SD only** in this configuration the whole system will boot without the need for a NOR/NAND flashes storage, all images and the root file system will be fetched from the SD card === 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.
