For the sake of simplicity, the same approach described [[AXEL_ULite_and_SBC_Lynx_Embedded_Linux_Kit_(XUELK)#Target_setup_and_first_boot|here]] will be used. In other words, a microSD card containing Linux kernel image, device tree blob, and decompressed root file system will be used. It is usedworth to remember that such a microSD card can be created following the instructions described [[How_to_create_a_bootable_microSD_card_(XUELK)|here]].

It is quite straightforward to prepare Starting from such a microSD card containing , we need to do the following operations:*adding a Debian minimal modified version of the Linux kernel image*replacing the default Yocto root file system that replaces the one delivered along with the XUELK, with the Debian one. To get The following box shows how to perform such an image, issue operations once the card (mapped as <code>/dev/TBD</code> in the following command on your example) has been connected to a Linux host machine:[1].

To verify You can now remove the card from the host, and plug itinto the slot of SBC Lynx. After powering it up, stop the automatic boot process, and edit the <code>mmcboot</code> variable as follows:

sha256sum debian=> edit mmc_loadkedit: fatload mmc 0:1 ${loadaddr} xuelk-81.7-bare-armhf-2017-01-141.tar3_uImage.xz159e1a6addc35bbfff03b5eafd5cb741086a8a016d5ab9572ab122ce64d63e5e debian-8.7-bare-armhf-2017-01-14.tar.xz

After inserting Then start the microSD card into the adapter connected to the host machine, it is possible to decompress Linux kernel by issuing the <code>.tar.xzrun mmcboot</code> command. The Linux kernel should boot and mount the Debian root file system as shown in the <code>ROOTFS</code> partitionfollowing box (click on the ''Expand'' link to open it):<pre class="board-terminalmw-collapsible mw-collapsed">unzip => run mmcbootreading xuelk-1.1.3_uImage.debian7139232 bytes read in 353 ms (19.3 MiB/s)reading imx6ul-lynx.dtb31436 bytes read in 20 ms (1.5 MiB/s)FDT: override 'som_uniqueid' with 'e6b3f362:393d61d4'FDT: override 'cb_uniqueid' with '00000000:00000000'## Booting kernel from Legacy Image at 80800000 ...
