About Debian

Debian is a Unix-like operating system consisting entirely of free software.

Debian is one of the earliest operating systems based on the Linux kernel. The project's work is carried out over the Internet by a team of volunteers guided by the Debian Project Leader and three foundational documents:

Unordered List ItemUnordered List Itemthe Debian Social Contract,
Unordered List Itemthe Debian Constitution and
the Debian Free Software Guidelines.

New distributions are updated continually, and the next candidate is released after a time-based freeze.

Download Debian image

Download Debian from this link or via following command

$ wget https://static.grinn-global.com/liteboard-debian-stretch-lite-2019-04-12.img.tar.gz

Extract image

$ tar xf liteboard-debian-stretch-lite-2019-04-12.img.tar.gz

Install firmware on SD card

$ sudo dd if=liteboard-debian-stretch-lite-2019-04-12.img of=/dev/<SD card> bs=4M
$ sync

Where <SD card> points to your SD card device.

Some distributions are automatically mounting all hot-plugged disks. In such situation please unmount SD card before dd … command.

Make certain that of=… points to your SD card. In case of mistake (when of=… points to your system disk) you can damage data on your system disk.

Show how to find SD card

Method 1

Insert SD cart to PC and check last lines from dmesg command output. Name assigned to the detected SD card will be presented as in the following example.

[ 6163.014768] mmc0: new high speed SDHC card at address 1234
[ 6163.024433] mmcblk0: mmc0:1234 SA16G 14.6 GiB 
[ 6163.025749]  mmcblk0: p1
[ 6163.375207] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)

Method 2

lsblk command will list all detected block devices where your SD card will be displayed.

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 232.9G  0 disk 
└─sda1   8:1    0 232.9G  0 part /home
sdb      8:16   0 223.6G  0 disk

└─sdb2   8:18   0 223.1G  0 part /
sdc      8:32   0 931.5G  0 disk 
├─sdc1   8:33   0     1K  0 part 
├─sdc2   8:34   0 903.6G  0 part /srv
└─sdc5   8:37   0    28G  0 part [SWAP]
sde      8:64   1   3.7G  0 disk 
├─sde1   8:65   1    16M  0 part 
└─sde2   8:66   1   3.6G  0 part

Device name

In both examples SD card was detected as sde so valid dd … command syntax is

sudo dd if=liteboard-debian-stretch-lite-2019-04-12.img of=/dev/sde bs=4M

Boot Debian on liteboard

Insert programmed SD card to the liteboard card socket.

Configure boot switches to boot liteSOM from SD card.

Connect your liteboard to your PC via USB ↔ micro USB cable.

liteboard will be automatically powered-up and on debug console you should see starting Debian as presented below.
