Resolution change of the video output in Openelec on Orange PI PC (Part1)

In the Orange PI Openelec image the default video output resolution is 1080p60. If our tv works with a different resolution we’ll have no image on the television.

To overcome this problem it is possible to change the resolution and fps  for the video output.

The micro sd has two partitions. We have to work in the vfat partition

schedasd

We have to modify the script.bin file.

contenutoschedasd

In the home partition of the debian user (sviluppo in our case) create a folder orangepi; inside this folder create another folder called  sunxi. Go into sunxi folder

Follow the instructions available from linux-sunxi site in order to modify the script.bin file. As first step install the required tools

Sunxi Tools

We have to install the libusb package, as described below

Install git and pkg-config

Now using git download the tool sources

Go into sunxi.tools folder

Execute the tools compilation

We are now able to modify the Orange PI PC parameters available in the script.bin file.

Create a folder under sunxi, for example scriptfile

Add to th ePATH variable the sunxi tools folders executables

Now in next article we can modify the parameters of video output in the script.bin file

Debian envinronment for embedded systems development

In this article we describe Debian 8.5 installation we’ll use to compile Openelec for Orange Pi PC, Enigma2 images and other operations for embedded devices.

Download  AMD64  Debian 8.5 iso

Debian X86_64

Proceed with the operating system installation on your system. It is recommended  to use a virtual machine like VirtualBox. Use at least  4 GB of ram and 50 GB of hard disk.

VirtualBox

Using VirtualBox it is possible the virtual disk creation with dynamic space allocation. After the operating system installation log on into the system with the user created during the installation; we used the “sviluppo” user id. It is possible to log on to the linux system using the graphical interface or through ssh to the IP address of the Debian system.

Add to sudo group the user created in the Debian installation; open a shell command window and execute

In our case we have the following output

sviluppo user doesn’t belong to sudo group. Execute the command

Enter the root password when required and execute

In our example

Reboot the system

At the reboot log on into Debian and proceed to add the packages repositories, if not already present.  Go to the /etc/apt folder

Backup the original file

Edit the file using for example the vi editor

It is possible to comment out the lines positioning at the beginning of the line, press i to go in editing mode and add the # character. Pressing the ESC key we go into reading mode and it is possible to move in the file using the  arrow keys. In case of errors in editing mode it is possible to avoid the last change using the key ESC+u.

Comment out the  lines

Add the following lines

To add the lines press o keys to go into writing mode with an empty new line; with copy and paste we can add all the lines or proceed manually for each of them.

To save the file and quit press ESC+:wq.

It is possible to use one of the text editors available in Desktop Envinroment on which we logged into to edit and save the file.  For example to use pluma editor open a shell command windows and execute

From pluma open the file /etc/apt/sources.list, make the changes described above and save the file.

Update the repository lists  and the packages

Install the development packages

Install an ftp server to use for files transfer

After the installation open the file  /etc/vsftpd.conf and uncomment the following parameter

Open the file with vi or pluma as superuser

With vi editor search the string with the command

Delete the # character positioning the cursor on it and pressing the x key.

Save and quit with ESC+:wq.

Restart the ftp server using the command

We have now the envinronment to compile, modify, develop  our embedded systems.

SD card setup for Orange PI PC Armbian in Linux

As already described in the previous article

Openelec SD card setup

also for the Armbian distribution we have to prepare an sd micro card.It is advisable to use a micro SD class 10 to gain better performances. As first step  we proceed to the Armbian  image download from Armbian web site

Download Armbian Orange PI PC

We choose for example the Debian Jessie Desktop Image.

We install 7zip package. In Debian we can use the following command
