L.S. Just put some thoughts to paper. http://imgur.com/a/z98zJ Just a mock-up, nothing thoroughly engineered Notes: 1. Make the battery exchangeable. 2. Reuse cheap cellphone batteries (mass produced) in adapter sleeves. 2. Make the network interface exchangeable. 3. Make adapter sleeves for the most common cellphone batteries. Some benefits: - Batteries have differing lifespans than screens/cpu's/network systems. - Battery technology evolves rapidly. - Every new cellphone has a different battery format. Cheap sleeves can be made to accommodate the cheapest available battery. - Wireless/Wired network technologies are abundand and evolve rapidly. - The wifi dongle can be exchanged with a wired variant - The wifi dongle can be exchanged with an new network technology bg/n/ac 5ghz channels etc - The wifi dongle can be exchanged with an roaming network service, 2G, 2.5G, 3G, 4G. - The wifi dongle does not need to be pre bundeled. User can choose his/hers own - The wifi dongle can be exchanged with a usb camera low or highend The bottom USB slots can be used as a connector for charging stations, docking stations, keyboard docks, dual screen, etc. P.S. It's been awfully quite around here..... Kr, Mike

ICE xPC Modular Computer
by Jean-Luc Aufranc 19 Jan '14

19 Jan '14

There's a project whose concept is somewhat similar to EOMA-68, but they are using Intel bay trail CPUs for now. That's the Indiegogo page with all details: http://igg.me/at/icecomputer/x/1760545 For a summary, you can check my blog: http://www.cnx-software.com/2014/01/19/ice-xpc-modular-x86-computer-is-as-s… The campaign perks may be delivered too late in the future to be successful, but it's yet another project with modular CPU boards.

Hello everybody step by step informations are coming out from this new "player". informations I could obtained from them are: for the LAN chip it is :AR 8035 for the WIFI chip is: RTL 8188EUS the "schematic" of the platform can be found here: http://www.tbsdtv.com/download/document/tbs2910/TBS2910-Matrix-ARM-mini-PC-… and how to install the O.S on it is here: http://www.tbsdtv.com/download/document/tbs2910/How-to-burn-a-new-OS-into-e… and about the GPIO, I've put a copy here: http://www.fishspirit.org/TBS2910MatrixARMminiPC/ and the other informations about the GPIO I've obtained are: [root@matrixtv ~]# ls /sys/devices/virtual/gpio/ gpiochip0 gpiochip160 gpiochip32 gpiochip96 gpiochip128 gpiochip192 gpiochip64 it's a bit "light" for the moment. so we'll see... I have a question about the miniPCie port included on this platform, what kind of interfaces/extensions can we find for it? (I googled about it, and most of them are SATA but there is already one on it, so ?...) is there someone to open my eyes?

AllWinner A31 and PowerVR Driver Development Kit
by Jean-Luc Aufranc 17 Jan '14

17 Jan '14

Somebody from Imagination Technologies left a comment on my blog: http://www.cnx-software.com/2014/01/10/a80-optimusboard-features-allwinner-… The part related to this mailing list is: "Secondly, the links below contain DDK (Driver Development Kit) source packages distributed through our customers: ..... Rhombus Tech (1.10 onwards) http://git.rhombus-tech.net/?p=linux.git;a=tree;f=modules/eurasia_km;hb=163… " This repo points to something called eurasia_km for A31 Android 4.2. This is clearly related to the PowerVR GPU A31, but I don't really understand what can be done with this source. Would it be possible to use it with a Linux distribution, or the binary part still relies on the Android drivers? I've also seen Mele play 4K videos in Linux on AllWinner A31. Does that mean a Linux port with GPU and VPU support is technically feasible with what is available today?

[EOMA68] RFC and Review: SD/MMC and SPI added to specification
by Luke Kenneth Casson Leighton 26 Dec '13

26 Dec '13

after some thought (and thank you for the comments), 1 SD/MMC and SPI interface have been added to the EOMA68 specification. as these pins are already brought out on the EOMA68-A20 CPU Card, there is no modification of the EOMA68-A20 CPU Card design required. only those people with the [first] A10 CPU Cards (of which there were only 5 made, and i have 2 here) would be affected. comments appreciated: http://elinux.org/Embedded_Open_Modular_Architecture/EOMA-68 l.

Help Taiwanese open-source GPS hardware a bit
by Paul Sokolovsky 25 Dec '13

25 Dec '13

Hello, Sorry for potential spam. There's a campaign at Indiegogo to develop a board with GPS MCU which would allow to run user programs alongside the GPS stack. It's unclear how open the GPS stack itself would be, but even if it will be a binary blob, it's still great progress comparing to current GPS chipsets. As an extra, MCU feature SPARC architecture, which alone worth to be present in every geek's personal computing museums. And early bird price starts at pretty low for 32bit "maker" scene figure of $15. So, please bid and spread the word - if it dies off, everyone talking of open source and open hardware should feel ashamed. http://www.indiegogo.com/projects/navspark-packing-32bit-features-and-gps-g… -- Best regards, Paul mailto:pmiscml@gmail.com

"[EOMA68] RFC: ADDITION OF SD/MMC TO STANDARD."
by Luke Kenneth Casson Leighton 24 Dec '13

24 Dec '13

i'm giving serious consideration, even at this late phase, to adding SD/MMC to EOMA68 by way of the GPIO pins as a multiplexing option. this would not have any impact on the EOMA68-A20 CPU Card: in fact, the only reason this can be considered at all is because the pins *happen* to be multiplexed as SD/MMC and GPIO *anyway*. this would also happen to give EOMA68 an SPI port as well. the idea came to me because it's something that's been forced on EOMA-26 due to the small number of pins (26) on EOMA-26. after looking at dozens of SoCs i don't think i've seen a single one these days which *only* has a [non-multiplexed] SD/MMC port. even if there was one that did (at an affordable price), a cross-bar buffer IC would take care of that. does anyone have any objections, and/or can think of any gotchas which would prevent SD/MMC from being added as a non-optional multiplexed option to EOMA-68? l.

Exynos 4412 quad core 1.7GHz with 2GB DDR built into chip: http://www.cnx-software.com/2013/12/23/hardkernel-unveils-59-odroid-u3-boar… Amazing board similar to cubie selling for USD 59. They use eMMC to gain 4x speed, runs Xubuntu 13.10 already. The heat sink requirement probably makes it a non-starter for EOMA unless a flat heat pipe could be slipped into to somehow :)

Interesting chip the LPC1343
by joem 23 Dec '13

23 Dec '13

Hi, I ordered this FPGA dev system: http://www.kickstarter.com/projects/1575992013/logi-fpga-development-board-… [Already over subscribed by x5 and still 24 days to go :) ] I found it has a $2 LPC1343 ARM cortex chip which has within it which has USB MSD or MSC (Media Storage Device/Class) driver built into the ROM of the chip! Just connect the USB and it will open as an attached mass storage device, and then drag and drop files into it to program it! It doesn't need a programmer http://dangerousprototypes.com/docs/LPC_ARM_quick_start The IDE is by Code-Red which is Eclipse and it is available for Linux. NXP have bought them out recently and now 256k of code generated by it doesn't require a license. I can't find any more such chips from NXP. (The ones that are available with USB require software to be developed and programmed into the device that turns it into an MSD - which is great if you got the time.) May be this chip useful to add on to MEB or other bits of hardware to to add features such as programmable switch mode power supplies or extend general purpose IO - because it simplifies software development for those chips and their programming, and easier to update firmware once a project has shipped.

how to get 4096-bit RSA private keys for free.
by Luke Kenneth Casson Leighton 18 Dec '13

18 Dec '13

http://www.cs.tau.ac.il/~tromer/acoustic/ including from secure "Tempest" servers. i find this hilarious. they're using power-fluctuation analysis using either a physical contact with the machine (skin-contact with the metal case is enough but an earth point on the VGA or USB cable is better), or, my favourite, is listening for the distinctive sound made by inductor-capacitor feedback loops in the power circuits. apparently some mobile phone microphones are just about good enough to hear the 20khz+ whine: that's enough to determine the power consumption during the RSA key calculations, and that's good enough to get any private key. takes a hell of a long time, but that's ok :) all those "secure servers" out there? all you have to do is lease space to put in your own co-located server with an ultrasonic microphone and it's game over for neighbouring web server certificates. absolutely hilarious. sorry i just had to share this with someone. l.

upstreaming the fex for the eoma
by Marco Martin 16 Dec '13

16 Dec '13

Hi all, I would like to upstream the script.fex file (or the files?) for the eoma68 into https://github.com/linux-sunxi/sunxi-boards my fex at the moment is: https://github.com/notmart/sunxi-boards/blob/master/sys_config/a20/eoma68_a… that seems to work correctly. however I'll forward some comments on it that were made on the linux-sunxi irc channel (oliv3r that i think he maintains the sunxi-boards repo): it has enabled several things that aren't available on the improv (wifi, touchscreen on i2c.so, enabled cameras) basically boils down to try to do a fex file that catches all the possible feature boards vs one fex file per feature board. Not knowing a lot about this in particular I can pretty much just refer what i was told and let you guys decide how we want the fex file, or the multiple fex files that would end up in that repository (at least i think it makes sense to put everything in that place) Cheers, Marco Martin

A bare image for booting from NAND
by Marco Martin 13 Dec '13

13 Dec '13

Hi all, so this is the first outcome of my quest for booting from the nand, and i tought it would be nice (and useful for others) to share: http://makeplaylive.com/~notmart/Improv/eoma68-A20-nand-bare.raw.bz2 This is a dd of the nand in the following situation: * it has two partitions: "boot" 16 megabytes long and "root" that is everything else * "root" only contains /lib/modules, all the rest is empty (nicely zero-ed, so it compresses nicely) * Boot0 and Boot1 come from https://github.com/hno/allwinner-boot , revision d29c34b , modified to *not* search for a "boot" partition starting with "ANDROID!" magic. An open issue here is that version will need to be GPL'd (latest and gpl revision won't work, i suspect is for a different kind of hardware) * U-boot comes from https://github.com/linux-sunxi/u-boot-sunxi/tree/lichee-dev-a20 , default boot arguments modified in sun7i.h * the kernel uImage and modules, as well as script.bin come from my Mer OBS repository: https://build.merproject.org/project/show?project=home%3Anotmart%3Anemo%3Ad… this image can just be dd-ed on /dev/nand then the kernel will boot. It won't do much else because there isn't any root filesystem, but that's kinda the point, this image can be used as a start for any distributin image Cheers, Marco Martin

Re: [Arm-netbook] Auto-discard notification
by luke.leighton 13 Dec '13

13 Dec '13

hi oliver, thanks for your support here. we'll get there. will have to see about FOSDEM. regarding linux-sunxi: what pissed me off was two things. the first was that i wasn't even told it was happening, wasn't consulted, and found out *months* after it had been set up. the second is that the decision was taken to use non-free proprietary hosting services when, if i *had* been consulted, i would have been able to point people in the direction of several the highly-experienced software libre sysadmins i know who would have immediately said "yes" if anyone had bothered to ask them if they could add domain names, mailing lists, or any number of software libre packages, and they would have helped run them at zero financial cost, because that's what these highly-experienced people do already, for dozens of custom project, and have done now for decades ... but you know this already: i've mentioned it a number of times. so, to repeat: if you would like me to be directly involved in the linux-sunxi community, *stop* using google's proprietary mailing list. subscribe it as a one-way archive if you want, and subscribe gmane.org as well to it (like arm-netbooks is) so that people can use a web browser to post and still maintain thread continuity. also i will not submit patches via github: i revoked my account on it because again that is a non-free proprietary service. so you neither have a means for me to notify the sunxi community of patches, nor do you have a means for me to push patches _to_ the sunxi community, because you didn't consult or involve me in the creation of the sunxi community and chose to use proprietary software services for quotes convenience quotes. if that's useful to you to continue to maintain that situation, please continue to do so - nobody, least of all i, will tell you what to do. i will however advise you each time this comes up what the consequences are of the decision that was made, and the consequences are that you will have to work harder and harder to keep track. l.

Flashing the NAND
by Marco Martin 13 Dec '13

13 Dec '13

Hi all, I have an A20 based eoma68 card. I have now an image based on the Mer distribution that can boot and runs fine from the microSD card (following http://rhombus-tech.net/allwinner/a20/boot/ and http://www.gplsquared.com/eoma_boot/eoma_boot.html) but the next necessary step is to flash a booting image to the internal NAND of the eoma68 (and in the end make an image that can be installed by default from the factory). I understand there have been some progress (I see drivers for it in https://github.com/linux-sunxi/linux-sunxi/tree/wip/linux-sunxi-3.4/cubiebo… but nothing that looks like it shows up in /dev?) I was wondering what is the procedure for it? did anybody managed to obtain a booting linux distribution from the nand? (seems a proprietary windows application is needed for the flashing?) Cheers, Marco Martin

Component sourcing guided trip to China
by joem 11 Dec '13

11 Dec '13

Hi Luke, Aaron, Chris, Neil, The company I work for is expanding and I'm in Far East sourcing components. If you come to Hong Kong on 2nd week of February with a China Visa I can take you on component sourcing shopping trip to Seg Electronics Market in Shenzhen and the electronics and metal markets in Guanzhou. SEG is so big, it need at least 5 days to crawl through all the factory shops. Guanzhou markets about two days. Absolute eye opener for all things that happen. Every conceivable types of components, modules, in all sizes, and items you have not yet seen are to be found there. Normally I buy samples and send them by post so that I don't weighed down. The factory that I'm seeing can arrange all that. (Anyone involved in deep end of manufacturing is welcome to tag along.)

How best to get touch working on EOMA?
by joem 10 Dec '13

10 Dec '13

How best to get touch working on EOMA? I'm thinking may be a better bet is to have a mouse like generic USB gadget built. Then you would connect the resistive or capacitive panel to it, and it would convert the signals to standard mouse signals. I've got touch signals being picked up by the drivers cubie but need to run some software to get it to cooperate with X - so a bit fiddly even if touch pins are available. EOMA doesn't have the touch pins brought out, so having such a modular unit could benefit EOMAs and other similar boards.

EOMA lapdock
by freebirds＠fastmail.fm 10 Dec '13

10 Dec '13

There has been much discussion on creating an EOMA laptop. In the meanwhile, an EOMA lapdock can be created by connecting an Improv board to a lapdock. A lapdock does not work well on a lap though. A lapdock needs to be on a desk or table. With a slight movement of my lap, the touchpad and keyboard freeze on my second Atrix lapdock while connected to a raspi. Sometimes pushing the Blackberry 900 Y splitter data cable tigher onto the lapdock's USB plug fixes the problem. Other times, it does not and sometimes causes shut down. I returned my first Atrix lapdock because slightly moving my lap caused the monitor to turn red and buzzing. I had to keep pushing the HDMI adapter tighter on the lapdock's HDMI plug. Matthew Ritchie manufactured custom HDMI and USB cables to insert inside an lapdock to replace the lapdock's plugs. I do not know whether his cables solves the wiggle problem. I watched videos on disassemblying a lapdock, but haven't tried it. There are four models of lapdocks. The 100 lapdock cannot be opened without breaking it. matthewjohnritchie(a)gmail.com http://www.raspberrypi.org/phpBB3/viewtopic.php?f=48&t=59033&p=443285&hilit… -- http://www.fastmail.fm - Choose from over 50 domains or use your own
