==microSD layout==
The microSD card provided with BELK/BXELK is partitioned as shown in the following image:
[[File:BXELK-uSD-partitioning.png|thumb|center|600px|microSD card partitioning]]
TBD
Most of storage space is occupied by two partitions:
*a <code>FAT32</code> partition (<code>mmcblk0p1</code>) containing:
**U-Boot <code>bootscript</code>
**Linux kernel and DTB binary images
**XUELK virtual machine image in OFV format ([[Managed_Virtual_Machine_(MVM)|MVM]] basic version)
**7-zip Windows executable file
*an <code>ext3</code> partition (<code>mmcblk0p2</code>) containing the root file system for the target.
<code>bootscript</code> and root file system are used to boot the target as described in [[#AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)|this section]].
It is worth remembering that the microSD card is [[Booting_options_(SBC_Lynx)|bootable]], because U-Boot image is stored at address 0x400. However, even if U-Boot is run from the microSD card, '''the environment is retrieved from NOR flash'''.
