Fwd: Allwinner A33 Quad Core 2GB board in development
by Luke Kenneth Casson Leighton 05 Sep '14

05 Sep '14

this has gone out to debian-arm and fedora arm lists, if anyone else would like an A33 CPU Card let me know. l. ---------- Forwarded message ---------- From: Luke Kenneth Casson Leighton <lkcl(a)lkcl.net> Date: Fri, Sep 5, 2014 at 10:33 AM Subject: Fwd: Allwinner A33 Quad Core 2GB board in development To: Fedora ARM <arm(a)lists.fedoraproject.org> i'm doing an EOMA68-A33 CPU Card which will cost $5600 to complete the layout and 5 samples. i can cover that cost over a couple of months, so it is going ahead, and first (working) 5 samples should be done and received by Dec 2014. if there is anyone who would like to buy either one of the 5 samples (at a premium) or would like to be part of a group-buy please do contact me directly. specifications are: * Allwinner A33 Quad Core ARM Cortex A7 * 2GByte RAM on a 32-bit interface * 18-pin RGB/TTL up to 1280x800 resolution * on-board SMC9514 USB-Ethernet IC (10/100) * 2x USB2 (480mb/s) on EOMA68 interface * 1x USB-OTG (can be used to power CPU Card) * 1x Micro-SD note that unlike the A20 CPU Card this one does *not* have HDMI out (it's a lower-cost SoC) and the max resolution really is limited to 1280x800 because the A33 is a tablet SoC... albeit a quad-core one. news as it happens will be at http://rhombus-tech.net/allwinner/a33/news/ l.

thoughts about a set top box
by Simon Kenyon 02 Sep '14

02 Sep '14

i've been thinking about this over the last year to two. decided to put it out there to see if anyone a) had any comments b) knows of existing hardware or c) interested in collaborating the idea is for a device which can act as a set top box, either as a pure player of content stored or streamed from elsewhere or as a receiver of content using one or more DVB-S2/T2 tuners. design criteria: - linux - open source including all drivers and codecs - fast enough to render 1080p - hdmi out - bluetooth/wifi on board - all connectors on one edge of board so casework can be professional quality - tuners on board or pluggable. i had an idea to re-use the dimensions of a standard motherboard and instead of spci slots - have usb plugs instead. a tuner could then plug in like a pci card. - space on the pc for a 2.5" disk (see http://www.sinovoip.com.cn/ecp_view.asp?id=554) -- simon Simon Kenyon Managing Director.

discussion of operating systems on cpu cards
by Luke Kenneth Casson Leighton 28 Aug '14

28 Aug '14

after manuel asked if it was ok to have a specific CPU Card only support one OS, i had a bit of a think about that, and wanted to run an idea by everyone. the discussion is basically "should all CPU Cards work with all base units with all OSes?" meaning that we have a *three-way* (3D) matrix of options: a) CPU Cards b) base units c) OSes previously we had discussed the idea of OSes being able to auto-download (in some fashion) such that CPU Cards could adapt to the base unit. i have an alternative idea which i think may turn out to be more workable... at least slightly simpler. the idea is quite simple: * tie the OS to the CPU Card * have the OS adapt (as best as possible) to the base unit *without* needing OS updates (as best as practical) the implications are that, for example (manuel?) the Gaming OS should adapt so that if the CPU Card is plugged into a laptop base, it should go "oh, i am in a laptop base, i have no touch screen but that's ok i have a mouse, and oh look i have a joystick rather than a set of analog track-pads". given that most games have some form of in-game configuration options for keys/mouse/joystick etc. would this be workable at all? l.

eoma68-jz4775 cpu card
by Luke Kenneth Casson Leighton 28 Aug '14

ok so i contacted the people on linux-mips and the planned prototype cpu card was very well received, which was really nice. they pointed out however that creating 4 cpu cards is a leeetle ambitious :) well, it can't be helped, i've been waiting for some time to earn enough money to pay for them so there is quite a backlog! l.

microdesktop and eoma68-ic1t boards
by Luke Kenneth Casson Leighton 25 Aug '14

25 Aug '14

ok i've received a quote from a company that is recommended by ICubeCorp, it is only $750 for 5 micro-desktop PCBs and 5 eoma68-ic1t PCBs, which is very very good. probably something to do with them being tiny boards and only 4-layer. anyway i will send them the money at the beginning of september, will keep people posted. if they are good i will use them to do the eoma68-jz4770 boards as well. l.
