Re: [Arm-netbook] A20 deadline

I think you read this: >well, thanks to some questioning last month we worked out a way to >increase (negotiate) power up to 10W, and i am working on a proposal / >concept to get an 8-core 64-bit RISC-V SoC produced. And, didn't read this thread: RK3288 PCB first prototype assembled. I hate to add, because it seems Luke was sufficiently crass, but I'd like to explain why it was justified and appropriate, even if it comes off as insult to injury, it is only meant to explain so truly harmful stress can be avoided in the future. When you are communicating on this mailing-list, you are not contacting customer support and you are not engaging with a corporation, a corporate entity, or any type of public relations entity. When/If you backed this project you did not back any person or organization. We are the organization, you included even if you are the metaphorical equivalent to a lazy employee just like I am [at least, I admit it]. By messaging on this mailing-list, you are not messaging to this organization, but-rather as a part of it, because this is an internal communication channel where we [this organization] are collaborating the planning and design of our thing. Luke, being the one whom holds the funds we have gathered to build our things, is simply a very pro-active member of this organization that has existed long before this campaign has, whom has become a trusted agent of this organization with the sole purpose of performing our grande finale in this epic. Once that role is complete Luke will ultimately return to being like the rest of us until the certification mark is registered, that is to say hopefully if it is successfully registered. We owe a lot to Luke, being the still unconventional and still unfortunately somewhat amorphous segment of the Linux community dedicated to hardware that we are, [and, that is the only definition for organization I will provide here] Luke certainly seems on the path to fulfilling such prerequisites as would complete the mandate of such temporal authority, and perhaps deserving it, as only history can tell. This organization will still exist even after this grande finale which now should seem as ever impending as it ever has been, and as such it is only natural that we talk about the hereafter of this whole project. Luke, making mention of a proposal to build a RISC-V SoC was not supposed as recommendation for this project as even a "Lazy Employee" such as yourself [please excuse the metaphor] can obviously see that wouldn't work. There are still many more epics to be written after this one, and, with the temporal authority supposed to be placed in Luke's hands shortly hereafter [re-read that until you get the pun and can laugh, because you won't understand the sentence until you get the pun; it happens with the word suppose], I can trust that it will be a great one with great OpenCores. Yes, Luke must be accountable being trusted with these funds that the fellow is, but this type of questioning now is an insult because we are supposed to be doing this for ourselves. Luke's deadline is soon, but we, being that we are doing this project for ourselves, have no deadline especially being that the sooner we rush this the less work and the more likely to fail we are. The deadline here is partly on us to help Luke build these boards the best we can remotely, and, if Luke were to fail to create a board soon after we develop a promising prototype, then we question Luke and hold accountable thereof. That very clearly hasn't happened and, in fact, the opposite has very clearly happened and, if Luke, in celebration of completing part of the trust we had in him, sings song of the next epic we shall write and you question it in this way that you have, you are not only insulting Luke severely, you are identifying yourself very opaquely as the colloquial "Lazy Employee". Please pay attention.

New Eoma68 housing idea
by HeadsUpHigh 18 Feb '17

18 Feb '17

Hi, I think this indiegogo project has a very interesting form factor. https://www.indiegogo.com/projects/gpd-pocket-7-0-umpc-laptop-ubuntu-or -win-10-os-laptop--2#/ I think this kind of form factor would be ideal for a new Eoma68 housing. Especially if there is an m.2 slot inside the housing for extra storage( via usb 3.1 to sata3), this would make for a really good extremely portable computer with the added bonuses of the upgradability of the eoma68 standard as well as no space wasted for active cooling( like that machine has).

http://rhombus-tech.net/rock_chips/rk3288/news/ 2 updates from crowdsupply in the pipeline, i'll cf them later. also will update the latest news tomorrow when i have a chance to swap the USB cable over. all rather hilarious: i wired the OTG pins to the 2nd USB port and vice-versa. whoops. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

A suggestion why Systemd may be bad
by John Luke Gibson 16 Feb '17

16 Feb '17

Perhaps it is the idea that a linux machine should be wholly modular and attaching a library to a critical component of the system, shouldn't be a viable strategy for popularizing one's work. When a distro is forced to carry a package due to a dependency of a dependency, or any magnitude there of, it breaks a core separation of power there. The users depend on distro's to provide reliable packages, however if a package is intentionally interweaving files to make these dependencies simply a part of the file and therefore robbing the distro's the ability to choose a different dependency should another developer or team thereof prove more reliable or more suited for their distro. Systemd in this sense would be like microsoft robbing those wishing to distinguish themselves of the ability by increasing the magnitude of difficulty in doing so. Now, keep in mind, I am not fluent in any programming language and have not audited Systemd, nor do I know anyone who has. This is based on a compiled understanding of observations expressed in arguments both infavor and against Systemd.

Sorry, I just read your reply Mike. I think that answers any curiosity I had. I appreciate it very much. This is makes sense as I imagine it to be part of the problem GNU/Mach is trying to solve (separating components of the system better, and with more micro-managed permissions?). Anyway, above and beyond explaining, both Mike and Philip.. Thx!

Enough Space in the 15.6" laptop housing for an SSD?
by Mike Leimon 11 Feb '17

11 Feb '17

In light of all the recent discussions about journaling filesystems and system logging on systems with flash storage. I'm a feeling a bit curious to to know if there is enough space within that included "internal" usb cavity of the 15.6" laptop housing to be able to house a small M.2 42mm usb device. I'm thinking about a device like the following: https://www.amazon.com/Crest-NGFF-SATA-Enclosure-SY-ENC25040/dp/B0146DD6KM/ Perhaps if/when there is a rev 2 of the Laptop housing, it might be worth considering the creation and inclusion of an additional board which would both provide a built-in usb to SATA adapter as well as provide a location to install an M.2 SATA drive (with huge bonus points if it can support an 80mm drive). I might be an oddball but, I would also love to see the inclusion of a dedicated M.2 SATA board to the upcoming EOMA68 tablet design (even if there would only be room for a 42mm variant) to be a huge plus. I think that being able to use M.2 SATA drives would be a huge step up in quality from using uSD cards both from a reliability standpoint as well as speed. Also, if USB -> M.2 SATA board created was a USB3.0 device it would pretty much be able to run the SSDs at their full speed.

> So what happens on a violent poweroff? Just lose data? Sure, if you happened to be in the middle of writing to the card, but this isn't that big of a deal really.

passthrough card v0 quick status
by Luke Kenneth Casson Leighton 08 Feb '17

08 Feb '17

assembled here with my friend's equipment, i got the 9161A tab pin wrong (GND instead of power), and i managed somehow to reverse the order of the OTG pinouts 5-1, despite cut/paste from a known working board. after pulling up the 3.3v regulator and putting a top-mount OTG reversed in place of the mid-mount, powerup worked and the GL850G USB Hub came up. tomorrow i will test the tfp401a by... you'll like this... configuring an A20 board to do HDMI output, and wiring it to the passthrough card :) l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Re: [Arm-netbook] TIL: Intel's credit-card sized modular computer is "inspired" by EOMA68

It almost looks as if they don't have money to throw at everything any more. I'll bet they're tightening the strings in anticipation of AMD's comeback. ------ Original message------From: Paul BoddieDate: Tue, Feb 7, 2017 15:22To: Ralf-Peter Rohbeck;Linux on small ARM machines;Cc: Subject:Re: [Arm-netbook] TIL: Intel's credit-card sized modular computer is "inspired" by EOMA68 On Thursday 2.

Their embedded boards don't really seem to have been widely picked up, at least in the hacker/hobbyist mainstream (although maybe the Arduino 101 really has sold well), and what started with a higher-end Arduino competitor employing a Pentium-class CPU (Quark) became a 500MHz Atom-based product (second generation Edison) that has now led to this 1.5GHz Atom-based board (Joule).Paul
