2.0.0 March 2017 TBD

Introduction[edit | edit source]

Several "distributions" are available for embedded Linux devices. Yocto and Buildroot are just two examples of the most common. Nevertheless, for some applications the use of a desktop/server distribution might be preferable. Since they are not conceived for embedded platforms, these distributions have to be carefully tailored, in order to match hardware resources.[1]

This application note shows how to run one of such distributions - Debian Jessie - on SBC Lynx. It is assumed that the reader if already familiar with AXEL ULite and SBC Lynx Embedded Linux Kit (XUELK), as it is the basis of this work.

The procedure was tested on a SBC Lynx with ConfigID=0x0000000C (PCB revision CS214515A), starting from XUELK 1.1.3 binaries.



[1] Non-volatile storage footprint is the typical example. Disk occupation of a desktop distribution is measured in GB or tens of GB, while many embedded platforms have less the 1 GB of flash memory.

Initial configuration[edit | edit source]

For the sake of simplicity, the same approach described 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 worth to remember that such a microSD card can be created following the instructions described here.

Starting from such a card, we need to do the following operations:

  • adding a modified version of the Linux kernel image [1]
  • replacing the default Yocto root file system delivered along with the XUELK, with the Debian one. [2]

The following box shows how to perform such operations once the card (mapped as /dev/TBD in the example) has been connected to a Linux host. 

TBD

You can now remove the card from the host, and plug it into the slot of SBC Lynx.

After powering it up, stop the automatic boot process, and edit the mmcboot variable as follows: 

=> edit mmc_loadk
edit: fatload mmc 0:1 ${loadaddr} xuelk-1.1.3_uImage.debian

Then start the Linux kernel by issuing the run mmcboot command. The Linux kernel should boot and mount the Debian root file system as shown in the following box (click on the Expand link to open it): 

=> run mmcboot

Debian GNU/Linux 8

DAVE Embedded Systems (www.dave.eu)
SBC Lynx

Architecture: armv7l
Hostname: arm
Linux kernel: 3.14.52-xuelk-1.1.3 #3 SMP PREEMPT Thu Mar 16 09:28:51 CET 2017

default username:password is [debian:debian]

arm login:

By default, two users are defined:

  • user debian, password debian
  • user root, password root


[1] The only difference with respect to the XUELK kernel image is related to the WiFi driver. To make it work with the Debian root file system, it has to be built as loadable module instead of statically linked driver.

[2] The provided root file system is derived from this one: https://rcn-ee.com/rootfs/eewiki/barefs/debian-8.7-bare-armhf-2017-01-14.tar.xz.

Adding packages[edit | edit source]

Of course, one of the greatest - if not the greatest - pros of having a desktop distribution, is the availability of a huge archive of pre-built packages. They can be installed very easily with tools such as apt and pip.

Before installing packages, the network interface has to be configured, as it is disabled by default. To configure it with a static IP address (192.168.0.80 in the example), nano text editor can be used: 

  GNU nano 2.2.6         File: /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
#source-directory /etc/network/interfaces.d
auto eth0
iface eth0 inet static
     address 192.168.0.80
     netmask 255.255.255.0
     gateway 192.168.0.254











                               [ Wrote 9 lines ]

Please note the these changes will take effect after rebooting the machine.

DNS server has also to be enabled, in order to resolve URLs. Again, nano comes to help: 

  GNU nano 2.2.6            File: /etc/resolv.conf

domain localdomain
search localdomain
nameserver 8.8.8.8
















                               [ Wrote 4 lines ]

You can finally install the desired packages, as shown in the following examples:

WiFi (client mode)[edit | edit source]

The procedure is similar to the one described here. However, as the WiFi driver is not statically linked to the kernel image, it is necessary to load the module first:
