SD card insertion Please Insert the SD card into your device.
Power connection Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.
Power On Hold on the On/Off Power button - SW1 (as shown in the figure below)
SW1 - On/Off Button
Note: The system should turn on by default when the power is connected (without pressing the button).
Serial Connection Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows. Once you installed the necessary serial connection software, you should be able to see the following:
Enter “root” in the login like the above example and then you can move on to use the device.
The following stages need to be done in order to finalise the imaging:
Run fdisk /dev/mmcblk0 if using SD or eMMC.
Recreate the rootfs partition (mostly the second partition) by deleting it and then creating a new partition that starts at the next sector after the first one and extends to the end of the drive (or less depending on your needs).
Write the new partition, when prompt about ‘Do you want to remove the signature?’ then answer with Yes.
Run resize2fs /dev/mmcblk0p2 if using SD Card or eMMC.
In this stage the root partition should be big enough to start populating it; but first update the RTC clock.
Connect the RJ45 to your network with internet access (and DHCP server); and then run dhclient.
Update the RTC clock by running ntpdate pool.ntp.org and then hwclock -w.
Run apt-update commands below and then populate the root filesystem as you wish.
$ apt-get update && apt-get upgrade -y
Here is an example of the process until the 3rd step (include):
After those steps you should end the process in this way (step 4 to the end):
In the end you should see with “lsblk” that the partition size is in the required size.
