==Introduction==
From the software standpoint, [[Bora Embedded Linux Kit (BELK)|Bora Embedded Linux Kit (BELK)]] and [[BoraX_Embedded_Linux_Kit_(BXELK)|BoraX Embedded Linux Kit (BXELK)]] are built on top of Zynq Linux BSP released by Xilinx. Customization Customizations are added to support for the Bora and BoraX platforms, in particular at bootloader and Linux kernel levels. BELK and BXELK share the '''same''' software modules, even if they are based on different hardware platforms.
Reading of [[Host_setup_and_development_flow_(BXELK)|this document]] is strongly recommended to understand the logical structure of the kits and how the software components are related.
The following table details the software modules of BELK/BXELK releases.

*an <code>ext3</code> partition (<code>mmcblk0p2</code>) containing the root file system for the target.
bootscript and root file system are used to boot the target as described in [[BoraX_Embedded_Linux_Kit_(BXELK)BELK/BXELK_Quick_Start_Guide#Target_setup_and_first_boot|this section]].
It is worth remembering that the microSD card is [[System boot and recovery via microSD card (BELK/BXELK)|bootable]] and U-Boot environment is retrieved from (and stored to with <code>saveenv</code>) into the FAT partition as <code>bora.env</code>
