eoma and qimod

well, i must apologise to everyone, the effect that the situation with aaron has had on my associate is more severe than i thought, and that is actually a *good* thing rather than a bad one. the original goal - which is at the very top of the rhombus tech web site - is the one that i wish to see happen. my associates it turns out wish to make money as the absolute sole exclusive top priority and they are prepared to sacrifice all and everything - principles, ethics, relationships and more - in the pursuit of that absolute pathological goal. so the first thing that happened was that the rhombus CIC was shut down without my being informed. the second was that i was signed up as a Director of QiMod Ltd without my signature, then removed when the situation with aaron occurred. in between, the idea (suggested by aaron) was floated to use trademarking to protect the EOMA concept (and more importantly the end-users from being harmed) by mis-implementation. i've now received demands for cash up-front license fees for the EOMA concept that *i designed*, when i was planning to work profitably *with* the very people demanding those fees. this basically means that the very principles that i founded the original goal on [to bring together software libre developers with mass-volume hardware manufacturers at every stage of the product process in a mutually beneficial way] are being _completely_ violated by the associates i thought i could trust to help make them happen. so, aaron, thank you for helping to create a situation in which i found that out now, rather than later. so i'm now at a major decision point... but let me be absolutely clear: i *will not* be sacrificing any principles or ethics, and i *will* be carrying on the goal. i will be making one last attempt to make this clear to my associates over the next few days, but if they cannot understand how important those principles and ethics are then i will be forced to carry on without them. last but most important thing to say for now: to the people who have donated money over the past couple of weeks, if you would like it refunded now, please let me know. l.

New Micro Breakout Board? How To Quick & Dirty Expose Interfaces?
by Alexander Stephen Thomas Ross 23 Jun '14

23 Jun '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 while I wait for the micro desktop, I wonder howto connect to the rest of the interfaces on the board. stuff wires in the pin holes? hehe The err micro breakout board will need sata replacing with usb, so there might be a new batch? I wonder how hard it would be for me to make a ultra compact breakout board for my self, a quick and dirty one off.....? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTqHfbAAoJEOk7fWIzE1KNCNQIANlGwxjUp5dYapUsCSN5u3tU 5HegLe+vl1rwDFRdq1cpC1OtWoPzshuaHbKxcfceOLywXUAnRwBJsWKvAUaSOVNF 0ft5B7ywLk5Gy4wnolJ971QLoLV7XTmpomL/HmN4247kikUKYRpPu+0A/4ZAuDMN BGzviOZ+niM1uOAJlFnn7XoF/FriHXPWvSvxCR2zHUZ23i1WSUhh+8isB/XOylXd F8LyR1sbEVDgsCwzXfHx3xkzf7T4GQQv+9xd4++kgtXKj6UU/MQvTN/B1nm7zn0b 0Beq2cll4j9kKZbvXeURs3K7K1reDfoDgyc3I3rTc/V8Gmjl9XNSFOFzMqjIpEY= =tXfT -----END PGP SIGNATURE-----

[status] EOMA68-jz4775 CPU Card
by Luke Kenneth Casson Leighton 21 Jun '14

21 Jun '14

third one: in cooperation with ingenic we will be doing a JZ4775-based CPU Card, i have received the schematics and PCB EVB files just today, this is a dual-core 1ghz MIPS SoC with a dual 1Ghz X-Burst Vector Processor that can do i believe it's 720p video decode and 3D graphics. it's entirely software-based - no proprietary GPU or VPU - which means it will also be FSF Endorseable (hooray!). again we will follow their progress into next year's products, i would expect them to have a quad-core out that can do 1080p video decode which would be awesome if they did. power consumption is really low on the ingenic SoCs. i will put this one with 1gb of RAM. the layout of the EVB is quite spread out, but i have made some measurements and it is *just* (barely) possible to leave the DDR3 RAM layout untouched, the SoC will almost be hard up against one edge and the RAM against the other: it is going to be very tight, so there will be no extra interfaces except for an SD/MMC Card. it does however have GbE which is fantastic, and there are two USBs (one USB 480mbit/sec and one 11mbit/sec) - i will route these both to the EOMA68 interface just out of sheer peversity. more later as it happens. l.

ARM device - compiling linux software
by Michael Howard 21 Jun '14

21 Jun '14

Looking for another ARM device to assist in software builds, has anybody got any recommendations for a capable board/device available in the UK? I have some softwares/packages (not mine) that are just not cross-friendly. Cheers, Mike. --

jz4775 cpu card progressing, ddr3 crammed in, gigabit ethernet 80% done, about 25 components to still place, nand routing 95% done, PMIC 95% done, RGB/TTL routing 100% done, SD/MMC 98% done, planes/power lines 5% done. eoma68-a20, process initiated to get PCBs printed (handed over to someone else), likewise micro-desktop ic1 cpu card haven't looked at it in a week (busy with the jz4775), stands at about 60% done, needs a conversation with icubecorp. l.

If you previsouly used Axx Allwinner platforms in the past for making your packages I presume you're mainly using this platform as "production" platform. So if you are turning now to a Wandboard that has a FreeScale processor how will you manage? Are you going to use cross-compiling technic? If so, how/what do you think of the Radxa mini board on thes matters? What is your opinion? It looks cheaper than the Wandboard? http://radxa.com/specification/ Sorry in advance if I'm "out of subject". Thanks in advance for your comments. Regards Erix

[status] eoma68-a20 and micro-desktop
by Luke Kenneth Casson Leighton 13 Jun '14

13 Jun '14

ok thank you to two sponsors, we have enough to pay outright for the micro-desktop 1st prototype and part-way for the revised eoma68-a20 cpu card. one final check of the revised cpu card is needed (as well as waiting a little bit for some extra money) then it will be off to get the PCB checked and done etc. if anyone wants to take a punt on that they are more than welcome, i am planning to do just 5 but if anyone is happy to pay say.... $175 then you can have an early CPU Card with either 1gb or 2gb of RAM, it is your choice (and risk!). i will be getting 2 with 1gbyte and 3 with 2gbyte RAM done. l.

Doubt about USB in EOMA-68.
by Miguel Garcia 13 Jun '14

13 Jun '14

Hi all, I've been looking at this: http://elinux.org/Embedded_Open_Modular_Architecture/EOMA-68#Table_of_EOMA-… Are all EOMA-68 obliged to have 2 USB 2.0 (the first on pin 30 and 64, the second on pin 34 and 68)? If in the future there is a EOMA-68 compatible with USB 3.0, would this USB 3.0 be associated with the first USB 2.0 or the second USB 2.0? We want to use the USB 3.0 to create a USB 3.0 port (with the current EOMA-68 only be compatible with USB 2.0, but we want to be compatible in the future with USB 3.0) and use the other USB 2.0 to connect internally the WIFI, the BT, the USB IC audio .... And we do not want that, in the future, some new EOMA-68 be incompatible with this because we have chosen the wrong USB. Thank you.

quick update
by Luke Kenneth Casson Leighton 12 Jun '14

12 Jun '14

* jz4775 board layout looks feasible (just). have had to squash the DDR3 address lines as there are no wiggles, only straight routing on the dev-board, the DDR3 is hard against one edge and the CPU hard against the other,i have to ask ingenic to check * micro-pc needs another review * 2nd revision EOMA68-A20 still to go to PCB factory for gerber checks * IC1 PCB pretty much done component layout. v busy sorry short status. l.
