TERES DIY Laptop / Flexible flat cable Maniplation

« Last post by Charles Sabourdin on November 19, 2018, 08:51:35 PM »

Hi,

I bought Olimex Teres, and assemble it, but I had very hard time with the small FCP (Flexible flat cable) specially the power fcp (https://www.olimex.com/Products/DIY-Laptop/SPARE-PARTS/TERES-028-FPC-Pwr-Main/ TERES-028-FPC-Pwr-Main) I wonder if anyone as a suggest tool to manipulate the FFC.

I look at https://www.olimex.com/Products/Tools/HandTools/ but I don't have a clue to select the best tool.

PS: That you very much for this project it's great.

I have tested the performance of the rev.K board and noticed the performance issue with the uplink:

The same behavior is repeatable with the official firmware release #115, with the Armbian Stretch and with Buildroot (fixed u-boot 2018.09, CONFIG_GMAC_TX_DELAY=4). Does anyone have the same issue?

Yes I saw but I wanted be sure. Because I am so new this subject.

Actually I work for a project. I need play video and transparent shape. This video and shape should run on console(Same Rpi's hello_pi code). I did on Rpi with omxplayer and openmax library. I did play video and run some text and shape(I use hello_font code). And I controlled transparent(I think Aliasing) of this shape Without using x11(or any desktop). I don't know how can I do this on Olinuxio A13 board.

I search Gstreamer and VPU now. I want use GPU because otherwise the CPU so sweat. Any different suggestion on this subject?

From the schematic they appear to use different CPU pins (GPIOnn) so should be OK.

I'm a bit worried why you ask - did you try it and it didn't work?

A web search shows it is specifically for RPi, so if that is right then no.

Does A13 has omxplayer? Can I use it?

I understand. My problem this: I am new this platform. Actually I am new in world of linux. So sometimes I need help of system and prepared program. Because I don't have deep information about linux. And I need time to able do something. I will search some and I will decide for desktop. Thanks your information

Those are the desktop environments currently loaded onto that system. GNOME is another popular desktop environment, for example. LXDE is a popular stripped-down desktop environment where all the default applications require relatively few system resources to run. Openbox technically isn't a desktop environment at all but is actually just a window environment. An X server and not a whole lot else. In the standard configuration, you may run commands in a terminal and see the graphical output. This is the working environment I use myself because it is extremely customizable and requires very few system resources to operate.
