Exclave -- Factory Test Infrastructure
by Philip Hands 31 Jan '18

31 Jan '18

Hi, I just came across this: http://exclave.io/ as mentioned in this LCA2018 talk: https://www.youtube.com/watch?v=pcyuzB3qLVo and thought that it might be useful for testing EOMA boards. It's cute, as it lets you write tests in whatever works for you, and just pays attention to the last line of output, and the return code. You can knock up a shell script, say, and if you can run it on the command line and get it to work, then exclave can run it for you. This is what is used to run the factory test for Bunnie's chibitronics LoveToCode microcontroller boards, among other things. BTW The LCA talk includes some handy tips on how to make such tests work for factory workers who are not likely to read English, nor to have a lot of time/concentration spare.

Devicetree discussion
by Jonathan Neuschäfer 31 Jan '18

31 Jan '18

Hi, I've created a page on the wiki to collect some information about devicetree, so the exact scheme of devicetree support for EOMA68 housings can be worked out: http://rhombus-tech.net/devicetree/ Feel free to extend/correct/discuss it. Thanks, Jonathan Neuschäfer

New Economics Wikipage
by Jean Flamelle 29 Jan '18

29 Jan '18

I'm starting the new page to address ideas on how to incent more to support the project. Since cryptocurrency was a recent hot-topic and some appreciated my input there, I'll be starting with a brief rundown of why the topic is complicated and might one start if they want to deep dive into it. I don't want to give my opinion on which currencies we should accept, even standard ones, because the issue is so deep I'd rather help others break into the conversation. Mindshare is really crucial here, because this defines all-in-all the people the project supports, how much the project supports them, and who will be incent to support the project as a result. We don't want to goad people into spreading word, sharing references, and funding EOMA or FLOSS. We want to play nice and win their hearts then only after recognizing we've won them over convince them to do those things. The level of disclosure this mailing-list demonstrates such impeccable willingness to abide that principle, that is what really won me into participating. - Aside, I'm still going to be on and off contributing to the "proposed best practices" page. I would like to start with examples of what I consider pretty impressive projects. I am also interested in liberating CHIP, but I want to get a more thorough understanding of electronic circuit firmware before I move forward. As is important to say, I'd rather do well or have not done at all.

pyra computer

https://pyra-handheld.com/boards/threads/getting-closer.82436/ I cannot remember if I previously have posted about the pyra computer. You can notice some of the same problems you see about the pc card. It seems the pyra's cabinet has been made. The cabinet has no pc card port. Has lkcl been in contact with pyra? The cabinet has no pc card slot. Is the pyra's cabinet relevant to the pc card?

Libre RISC-V SoC
by Luke Kenneth Casson Leighton 24 Jan '18

ok so, from the anonymous benefactor (independent of the shakti team), the one who sponsored me with the zc706 FPGA developer board, he has just had an interesting meeting with MOSIS, and has confirmed that they have an LPDDR3 PHY, so in combination with the DDR3 *controller* that was developed and released by someone working at CERN, this would be the last major piece of the "interfaces" side of puzzle that, until then, blocked progress. so he asked, also, what would it take to get things ready within a year, to hand over the ASIC-based design to MOSIS, for them to turn it into an ASIC, and i said "a team of engineers would need to be paid for". he asked - and please note the question very carefully - "would USD 250,000 be enough?" to which i replied (genuinely) yes... if done carefully. software also has to be taken care of. please note: *that's as far as the conversation has gone so far*. it is still exciting, and the next phase would be to get a strong committment and then i can start finding people to do software bring-up and also develop the VLSI / VHDL which will put all this together - mostly that's glue logic for the interfaces (putting them onto a "Tile" interface if using the rocket-chip or BOOM architecture) but also designing a multiplexer GPIO bank. i'm also talking to jeff from nyuzi, he designed a software-driven "compute engine that happens to be reasonably good at 3D", the interesting bit being that he's focussed on working out which areas need performance improvements. this is something that's almost completely lacking in the published academic world... *because nobody in the academic world has designed and published a GPU!* we worked out that nyuzi is approximately 1/16th the speed of MALI400. roughly. although area-for-area it's quite hard to tell whether that's a fair assessment because you can't *get* die areas for MALI400 (anyone know anything better than these estimates? https://forum.beyond3d.com/posts/1176110/ ) and it's the performance / mm^2 / watt that's critical, we worked out that if you put in 2 nyuzi cores and managed to halve the number of instructions / pixel by replacing critical path blocks with hardware-rendering ones, you'd end up at about 25% the performance of MALI400 and that i feel would be "good enough" for a first version. i'd be interested to hear what people think, here. the *general-purpose compute* performance of nyuzi on the other hand is really good. anyway lots of planning to do. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

> Pičugins Arsenijs<crimier(a)yandex.ru> Thank you for your email. > computer card or a RK3399 mainboard If the pc card gets shipped, then I got one. I want to frame this enterprise a bit more. It must be a hobby thing. You are not obliged to anything and you can skip any time you want. I will not hold it against you. One reason why I will not put large money into it. That way it is not a big deal if we do not succeed. We should do without time frames. Shipping the pc card appears to lay months ahead. > would you be interested in a videocall > of some sorts? On forums I prefer to stay anonymous. If things turn ugly I can walk away. If required can we get by using an irc or another messenger? > drawing the PCB, I can show you > the basics of KiCad For preparation, maybe you could state some links I should have a look on? I should mention I have a solder iron and a multimeter. About my comments on the devices I wanted to express that I prefer less complicated solutions.
