Hi all, I've been working on a project in educational technology for some time now, and it's been about three months since I started looking into arm-linux and Armbian. About me Goal: sub-$100 computers with 11"or better display. Modular, easy to repair. Successor to OLPC. We will do it better. Backstory: I was with an NGO teaching English and Maths to underprivileged kids in North-East India, and I found that progress was startlingly slow. We were able to spend only two hours a week with these kids, and it was simply not enough. I was aware at the time of apps like Duolingo which were extremely effective due to fact that the student can self-learn on theit OWN TIME. So I started developing an Arduino based audio based English teaching device, which quickly became an STM32 project. Then I saw that Allwinner SOCs were going for $4.50, which could provide these kids with a fully working computer. Now I'm at a junction where I need teemmates and/or advice. Progress: * Fully running, most peripherals working * Localization tested and working in LibreOffice and Firefox, but buggy in Armbian Desktop layer (missing translations) * Wide display compatibility (HDMI/Composite/VGA combination) for less than $3 achieved Challenges: * Funding (I have two possible solutions, PM me for details) * Teammates for forming a company Main point of this post: I'm looking for anyone interested in such a project, for co-founding an ed-tech startup. We will probably be working as a non-profit, and most of the large offices will be in developing countries (cutting costs without compromising on living situation). The areas of expertise that this movement is currently lacking: * A qualified Electronics Engineer who specializes in PCB and hardware * Public Relations and Marketing person(s) * Educators who are willing to raise awareness in the education space, and want to use computers in their classrooms * Someone with proven business experience People of any nationality may apply (visa allows NGO employment in foreign most countries). Please PM me if you fit the bill.

After much trial and error, I cross compiled opencv against a live armbian rootfs mounted via sshfs. I've documented the steps (including rationale and troubleshooting insights) on my blog: http://studiow.cf/blog/post/how-to-cross-compile-opencv-for-armbian-with-gtk

I recently managed to cross compile openCV against armbian live sysroot mounted over SSH. Full tutorial here http://studiow.cf/blog/post/how-to-cross-compile-opencv-for-armbian-with-gtk . The board was Nanopi M1 and Armbian (armhf) 5.23 Xenial Desktop.

Well I just wanted to put it out there. Bounty is a good idea, and perhaps more workable. As a side note, I figured out how to cross compile opencv against the armbian sysroot mounted over sshfs, and I'll be making a tutorial soon for others! It will work with gtk and qtembedded too.

(Update) The problem was the tv module. Enabled by adding "tv" in a new line, to /etc/modules on the sd image file system. In Armbian 5.23, the tv module is loaded by default, and you only need to enable the tv in fex. Details can be found in this github repo I made. You want to look at the [disp_init] and [tv_para] in the nanopim1.fex.tvmod file

What if there was a pay per use ($5 to $10) build server for building a custom armbian image, including the ability to select: which distro which kernel which kernel modules a choice of server, desktop and server with qtEmbedded (for single UI devices with no windowing) a selection of common software packages (VLC, OpenCV) to be cross compiled the ability to upload an image and cross compile new software against it It could be a web based UI calling the armbian build script, with the best toolchain already installed, and dependencies set to be pulled i automatically (so hard to set up on a case to case basis). Just an idea I had, and it could be a nice new revenue stream for armbian developers too.

I checked it too, and [disp_init] disp_mode = 1 screen1_output_type = 2 screen1_output_mode = 14 [tv_para] tv_used = 1 the resulting script.bin works with the Debian, Ubuntu mate and ubuntu core images provided by friendlyARM, but the same script.bin doesn't work with armbian. It may be because of a module not being loaded. Does anyone have more info on this "tv.ko" thing? I have no HDMI monitor so can't interact with a running instance of armbian.
