{{ImportantMessage|text=In For [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#XUELK_software_components|XUELK releases]] 1.1.3 and older, in order to boot Linux from SD card files, '''the binary files must be renamed''' as follows:
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'''.
====How to create a bootable microSD card====
The following script can be used Please refer to create a bootable microSD cardthis [[How_to_create_a_bootable_microSD_card_(XUELK)|this page]]. Is has been tested with 16 GB microSD cards. In case you have a different size, you'll need to change the <code>sfdisk</code> parameters accordingly. The resulting card is partitioned as depicted in the previous section.<pre>#!/bin/bash

==== XUELK 1.1.3 ====
This chapter describes how to quickly start working with the XUELK kit. The following paragraphs will guide you through the setup and installation procedures.
===Kit registration===
{{ImportantMessage|text='''Customers are strongly recommended to register their kits'''. Registration grants access to reserved material such as source code and additional documentation.}} To register the kit, please send an email to [mailto:support-lynx@dave.eu support-lynx@lynx.eu], [[Development_Kits_Identification_Codes|providing the kit P/N and S/N]].
Please register your development kit by sending an email If you also wish to access git repositories containing source code, please follow the procedure described [[mailto:support-lynx@dave.eu support-lynx@dave.euAccessing_DAVE_Embedded_Systems_restricted_git_repositories|here]], providing the kit P/N and CODE.}}
===Target setup and first boot===
This section describes how to quick start SBC Lynx board delivered along with XUELK kit(see also the following image):
*connect a TTL/USB serial cable to J42 connector; J42 pinout is:
** 1: TX data
* change dir to the ext3 SD card partition
* delete previous files and extract new files from tarball archive as described [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#Update_rfs_on_target|here]]
===Developing the software for the target===
Please refer to [[Developing the software for the target (XUELK)|this page]].
