The Linux kernel running on the target can mount the root file system
from different physical media. For example, during the software
development, we strongly recommend using a directory exported via NFS
by the host for this purpose (see the example configuration called
net_nfs); however, for system deployed to the field, the root file system is
usually stored into a flash device.
7.2 XELK
AXEL Embedded Linux Kit (XELK for short) provides all the necessary
components required to set up the developing environment for:
● building the bootloader (U-Boot)
● building and running Linux operating system on AXEL-based
systems
● building Linux applications that will run on the target
The heart of AXEL SOM is NXP / Freescale i.MX6 Solo/Dual/Quad core
application processor. From a software point of view, NXP / Freescale
supports this processor family through so-called Linux BSPs. The Linux
BSP releases are published on a regular basis and the release packages
have a reference code as L<Kernel_version>_<x.y.z> (eg:
L3.10.17_1.0.0). For more details please refer to:

AXEL Embedded Linux Kit, in turn, is directly derived from
L<Kernel_version>_<x.y.z> BSP versions. Hence XELK documentation
often refers to L<Kernel_version>_<x.y.z> resources.
DAVE Embedded Systems adds to the latest BSP from NXP / Freescale
the customization required to support the AXEL/SBCX platform. For this
reason most of the documentation provided by NXP / Freescale remains
valid for the XELK development kit. However, some customization is
required, in particular at bootloader and Linux kernel levels.
