s5p6818
by Luke Kenneth Casson Leighton 21 Oct '16

21 Oct '16

i've met with zhongweisemi (nexell's authorised agent in shenzen), really nice people, i've got access to the s5p6818 and am doing a conversion of one of their reference designs to eoma68. this board will ***NOT*** be available as a replacement for eoma68-a20 crowd-funded pledges, the pricing and MOQs had been set and may not be renegotiated without significant loss of future business due to an obviously adverse impact (reneging on promised orders). l.

http://rhombus-tech.net/community_ideas/micro_desktop/news/Microdesktop_Rev… http://rhombus-tech.net/allwinner_a10/news/ briefly, mike very kindly took these photos, we're sorting out the components to get them populated, i'll be back in shenzen on tuesday for the rest of the 2nd 30-day china visa period, hopefully we can get these populated, tested, and approved for 1k production run of the A20 board and 500 for the microdesktop. we can then start testing and shipping, get them out to people. lots to do... l.

Some Pine64 Experiences (via Planet Debian)
by Paul Boddie 12 Oct '16

12 Oct '16

Hello, I saw this on Planet Debian today: "Once more this is where, once again, the story turns bleak. We find a very pretty website but no obvious link to the software (hint scroll to the bottom and find the "support" wiki link) once you find the wiki you will eventually discover that the provided software is either an Android 5.1.1 image (which failed to start on my board) or relies on some random guy from the forums who has put together his own OS images using a hacked up Allwinner Board Support Package (BSP) kernel." http://vincentsanders.blogspot.com/2016/10/the-pine-stays-green-in-winter- wisdom.html I wonder what the licence compliance situation is with the vendor's own software. And some of the other experiences, particularly involving reliability, give a depressing sense of déjà vu to anyone with any moderate amount of experience with ambitious single-board computer efforts where the vendor shipped hardware without proper software support, arguably to get "bottoms on seats" and to drum up business. The author also makes some pertinent remarks about form-factor proliferation which seems appropriate to mention here, too. :-) Paul

routing vpns over ssh
by Luke Kenneth Casson Leighton 12 Oct '16

12 Oct '16

i can't quite believe that i'm having to route my vpn access over an ssh tunnel in order to then put HTTP proxy over the VPN in order to get frickin internet access to my email and anything at all. the IP address of my server has been blocked *not* by the china government but by the cisco equipment where i'm currently located... ... which is in the lobby of allwinner's headquarters in zhuhai :) well done cisco! :)

looks like a great processor. interesting to see what happens with it. ---------- Forwarded message ---------- From: Christopher Barry <cbarry(a)symbiaudix.com> Date: Tue, 11 Oct 2016 16:05:49 -0400 Subject: anyone here running unstable on i.MX7?

crowdsupply updates
by Luke Kenneth Casson Leighton 09 Oct '16

09 Oct '16

for those people who are interested, i've sent an update to crowdsupply and another one today about shenzen. joe, you're right: internet connectivity between china and the rest of the world is massively-truncated. the effect is quite dramatic and goes a long way to explaining the entire economic situation here. businesses can't do business, basically. have found some parts suppliers, they're documented here http://rhombus-tech.net/suppliers/shenzen/ --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Future case idea: subnotebook/PDA with QWERTY keyboard
by Sam Pablo Kuper 04 Oct '16

04 Oct '16

It would be great to have a housing for the EOMA68 that is of a similar form factor to one of these devices: - DragonBox Pyra [1] - Openbox Pandora [2] - HTC Universal [3] or even: - HTC Dream [4] That is, an enclosure that can fit in a pocket, and has: - Hardware QWERTY keyboard - Touchscreen (resistive, ideally) that opens out from the keyboard - TRRS audio I/O - USB OTG Something like a miniature tablet PC, essentially. Bonus points if it is also "ruggedized": waterproof, shockproof, etc. Likewise if it incorporates a trackpoint or similar, for using the mouse cursor without needing to touch the screen.[5] Goes without saying that it should be licensed as a Free Cultural Work[6], i.e. under GPLv3 or suchlike. Why would it be great? Well, traditionally, people using a PDA had to synchronise their information between their desktop or laptop and the PDA, e.g. via a cable or IrDA[7] or Bluetooth. Now lots of people do this via "the cloud", but that just means going via someone else's computers, so unless that system is implemented on a zero-knowledge basis using client-side encryption basis, then whoever else's computers are being used also gets to see the information. That might be really private stuff, like contacts and appointments and correspondence. With EOMA68, that problem would be solved: while out and about where a laptop would be too bulky but a PDA wouldn't, just have the EOMA68 card in the PDA housing. When at a desk, put it in the desktop or laptop housing. No need to sync! That means: - No loss of privacy - Less need for energy-intensive data centres - No need to have two computers when one would do (less e-waste) - No worries about race conditions due to data getting updated on desktop and PDA before syncing. - No headaches, essentially! Is anyone working on such an enclosure and PCB? spk [1] https://en.wikipedia.org/wiki/Dragonbox_Pyra [2] https://pyra-handheld.com/boards/threads/the-day-the-pandora-goes-even-more… [3] https://en.wikipedia.org/wiki/HTC_Universal [4] https://en.wikipedia.org/wiki/HTC_Dream [5] https://www.youtube.com/watch?v=d4t9Ys8wI6k#t=4m45s [6] http://freedomdefined.org/ [7] https://en.wikipedia.org/wiki/Infrared_Data_Association

shenzen extremely poor internet connection
by Luke Kenneth Casson Leighton 04 Oct '16

04 Oct '16

apologies i believe it may actually be better for me to try using GPRS here in shenzen, it would be faster and more reliable. i will try to find ways to get better connections. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

C++ features
by FaTony 02 Oct '16

02 Oct '16

Hi. I'm making a C++ game engine and interested in supporting the A20 board. I wonder what features are available there. What's the gcc/g++ version? Is there a std::uint64_t type defined? Can it do 64 bit floating point?
