As in I sent them an email very cool. here, i am tempted to suggest riding on EOMA68 (and the much smaller miniature version, EOMA50) and that LibreSOC simply be put into Card form as part of a *range* of eco-conscious products. the reason for that is that the long-term environmental justification and e-waste savings for EOMA-compliant products is pretty clear cut and well understood, and the cost savings and benefits for endusers are also clear and easy to understand. http://rhombus-tech.net/whitepapers/ecocomputing_07sep2015/ LibreSOC *on its own* is just one component (a tiny one) that is below 5 percent of the BOM of any given eco-conscious product, and, in addition, LibreSOC processors can equally be used in eco-oblivious products. therefore as a minority component it has very little actual reduction in e-waste per-se.... *unless included in eco-conscious products*. and that's where the EOMA strategy comes in. l. (note: EOMA50 because it is based on re-use of 3.3mm CompactFlash Cards is much smaller and can fit into smartphones. EOMA68 which is creditcard size is just that little bit too big) -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

MNT Reform Campaign
by Paul Boddie 14 May '20

14 May '20

Hello, It got mentioned about two-and-a-half years ago on this list, but the MNT Reform campaign has finally begun: https://www.crowdsupply.com/mnt/reform Of potential relevance to those following EOMA68-related efforts might be various resources that the MNT Reform effort has made available: https://source.mntmn.com/MNT/reform Things like the PCB layouts, microcontroller firmware and case designs are published, although people have previously noted that Autodesk Fusion isn't a particularly libre-friendly format for the case designs. One could envisage adaptations of this for EOMA68-related purposes or something with similar objectives. Certainly, user-upgradeable functionality via an externally accessible PCMCIA-style slot (or similar, rather than the internal SO-DIMM slot) would surely be worthwhile exploring. Paul

Deja vu
by David Niklas 26 Mar '20

26 Mar '20

Hi luke, Linus (not Torvalds), mentions every project but yours when discussing this "lap dock", a laptop without internals to which you dock a device, such as a phone, or raspberry PI. It's known as the Nextdock2. https://www.youtube.com/watch?v=SIJAEcOL6sI It never ceases to amaze me how many copies of your project I come upon online. I almost think it is a great idea. :D Sincerely, David

How about an opensource nuclear reactor?
by David Niklas 11 Mar '20

Dear luke, Such a project might not be ligament (I'm not a physicist), but people seem to be taking it seriously. As of this writing 2 of the files are still missing "PRIMARY LOOP" and "STEAM TURBINE". https://www.open-100.com/ David

$ available: python programmers needed on LibreSOC
by Luke Kenneth Casson Leighton 05 Mar '20

05 Mar '20

hi folks i need some help with the chip layout, it would particularly well suit a student or someone needing part time income. the actual layout is quite straightfoward to do, if you have ever done PCB Layout it is pretty much exactly that... except it is done as a *python* program. you call a *function* to place an adder block, rather than use a GUI, and then view the results *in* a GUI in order to review them. here is one of the experiments, which will need significant tidying up: https://git.libre-riscv.org/?p=soclayout.git;a=blob;f=experiments5/doAlu16.… it is however "functional" and demonstrates the principle of routing smaller blocks then placing them and routing the larger block. this hierarchy needs to be about 2 maybe 3 levels deep, around 100 "blocks" which will need careful discussion. no *actual* "hardware" experience is required, it is simply "call this function to put stuff here, call the routing function, save the file, move on to the next block". anyone interested or know anyone who might be, do get in touch or pass this on to them. thx! l. -- --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Could you explain the details of the 3D mesa driver you need?
by David Niklas 05 Mar '20

05 Mar '20

Dear luke, I've been very curious about this, but I've waited until you were stuck in some place before asking so as not to busy you. I'm not arrogant enough to say I'll create the 3D mesa driver or even go beyond theorizing, but I'm very eager to learn. 1. How do we know when it works? Is there HW or an emulator system we can use? 2. How do we know it's fast enough? What do we benchmark it with? 3. What exact APIs do you want implemented? 4. Do you want it in assembly with C and/or C++ bindings or in one or both of C/C++? 5. Are there any special assembly instructions that this will need? If there's anything else you think would be useful, do tell. Thanks, David

Is everything okay?
by zap 02 Mar '20

haven't seen updates for a while and I wondered if its still being released, the eoma68 laptop. :/ I would appreciate some updates you know. If its okay. Sorry, if this sounds demanding, I am sure your running into your share of barriers.

EOMA68 Computing Devices Update: Measurements and a Hypothesis
by Paul Boddie 24 Jan '20

24 Jan '20

Hello again, I saw the latest update when it was issued a few days ago, with these details being particularly important: "PCBs are etched with acid, and when the tracks or pads are particularly close together (such as with BGA balls), not enough acid gets in to eat away the copper, and (in a very indirect way) the BGA pads end up being far larger than they should be. This, in turn, means that when the IC is put on the PCB and heated up, the BGA balls (which are made of solder) will spread out much farther, and potentially even spread so far that they contact each other and short out." https://www.crowdsupply.com/eoma68/micro-desktop/updates/measurements-and-a… >From what it says, it rather sounds like same (or a similar) problem is being encountered as the one which happened with the Ingenic JZ4775 boards: "When the first 6 samples were done, only one was found to be working: for some reason the DDR3 BGA solder balls had spread and caused short circuits. One of the samples was still with the factory, and that too was found to have shorts. Mike has been extremely helpful, and this is the first time that he's been involved with BGA, where his uncle's factory has been the one that assembled the samples." http://rhombus-tech.net/ingenic/jz4775/news/EOMA68-jz4775_XRay_Photos/ At that point in time, I don't remember any more news about resolving the matter, and with the campaign being finalised the priority was no longer to get these boards working. But perhaps one of these situations informs the other, or maybe they inform each other somehow. Thanks in any case for keeping us updated! Paul
