aorus x3 plus v6
by Luke Kenneth Casson Leighton 12 Dec '16

well, i have a new development laptop, one that i'm actually happy will last several years and be up to the challenge of being absolutely hammered without even coming close to going beyond its design spec. it's an 8 core 3.2ghz i7 which can be overclocked to 4ghz. RAM maxes out at 32 GB of 2400mhz DDR4 RAM. it can take *two* PCIe NVMe SSDs, which i've confirmed can run at 485 MEGABYTES per second write speed and a whopping 2100 MB / sec read speed. who designs this stuff?? it's so bonkers i'm having a hard time getting my head round the specs... which continue with a hybrid graphics setup: the Intel skylake HD 5500 normally controls the LCD, but there's a headless co-processor (using "optimus" or "primus" - apt-get install bumblebeed) in the form of a GTX 1060 with SIX gigabytes of DDR5 RAM. 3200 x 1800 14in LCD just tops off the list of insane specs. oh, and as long as you use the 4.7.8 linux kernel under debian, *all* the hardware works. there's a few niggles but i can sort those out as things progress and become more confident with it. full report's at http://lkcl.net/reports/aorus_x3_plus_v6.html and yes, i used angband.pl "nosystemd" packages. i considered it to be better to be using debian with all dependence on systemd and libsystemd removed than it would be to try to convert to devuan, where they've clearly established themselves as a "Reaction Against" systemd yet their charter says "we are inclusive of all init services". i can't endorse or live with that kind of lack of integrity, despite loving everything else that they're doing and achieving (warts and all: thank you phil for sending privately that evaluation report you did of their work). the only real niggle about using this machine: god is it way too recent hardware. 4.8.* kernels don't work fully, 3.16 kernels don't work fully, i had to go with the 4.7.8 kernel and compile it up myself from source. i also haven't had to actually use debian/sid in a long, *long* time. have to keep an eye on that.... l.

Failed upstream port on the "Hercules eCAFE Slim HD"
by Denis 'GNUtoo' Carikli 07 Dec '16

07 Dec '16

Hi, Yesterday I bought a "Hercules eCAFE Slim HD", which is a small netbook with: - An IMX51 SOC and 512M of RAM (probably the maximum supported by that SOC) - A 1024x600 glossy display (sic[1][2]). - a 8G eMMC with the system - 2xSD slots - A switch that is under a trap that switches the SOC boot modes. Flipping that switch permits to boot from an external SD card (for recovery or for booting the system) It could be used as a computer that is impossible to persistently compromise assuming that the switch is always set to boot on an external SD card or that the internal eMMC is destroyed or removed. It was also interesting for me as I'm familiar with the I.MX SOCs, and that I was looking for a device to port parabola to. This would have been a fast port. Unfortunately the device bought was already opened, and the keyboard connector was dammaged. I failed to notice that. So I prepared a dts for it and compiled a kenrel to test, but the keyboard wasn't working properly since the last time I opened it, so I decided to fix that first. Unfortunately I broke it while messing with the broken keyboard connector. Probably a short circuit. The SOC doesn't enumerate anymore on USB and the device doesn't react when I press the power button. The DTS is pretty minimal and was intended to get a shell on it trough g_serial. It was produced by looking at the differences with the "imx51-babbage" board on the vendor provided kernel, and re-applying the lack of differences in a DTS. So I publish it in case someone wants to test or to continue the port. As I have a hard time finding such devices in France, the port will probably be abandoned.

t-firefly RK3399 in crowdfunding
by Mike Leimon 05 Dec '16

05 Dec '16

Since as I understand it, the people at t-firefly have been pretty helpful towards getting the RK3288 EOMA board put together, I figured I would point out that they have just launched a crowdfunding campaign to build a RK3399 development board. https://www.kickstarter.com/projects/1771382379/firefly-rk3399-six-core-64-… I'm not sure if that rk3399 processor would be able to work for a future EOMA68 design however, if it did, it would bring some cool advantages. It looks like it supports USB 3.0, it is a 64-bit processor, and like the RK3288, it can support 4 GB of memory.

RK3288 EOMA68 PCB
by Luke Kenneth Casson Leighton 04 Dec '16

04 Dec '16

http://hands.com/~lkcl/eoma/rockchip_rk3288/ http://rhombus-tech.net/rock_chips/rk3288/firefly/ for anyone who's interested, i've published the PDFs of both the 8-layer PCB and the schematics. i'm also documenting resources for installing mainline u-boot and linux kernel on the RK3288 firefly (t-firefly kindly sent me a developer board). apparently there are people who have installed debian stable on the firefly (for headless use) out-of-the-box, which is a really good sign. the RK3288 because it's a slightly older SoC which was used in the Asus C201 chromebook, it seems to have extremely prolific "HOWTOs" out there, as well as stable support in the official chromium kernel releases and a stack-load more. the only thing which is a complete utter pain: the 2nd USB controller (not the one that provides both 1 USB and 1 OTG port) has at least two known hardware bugs. first is: it doesn't support USB 1.1 devices (argh...) and second it doesn't come back up on resume. fortunately the *other* USB controller - the one that has 1 USB2 Host and 1 OTG port - works perfectly. on the firefly rk3288, i tried the OTG Host converter cables i have, plugged in a USB keyboard, up it came first time. i think the RK3288 would be an awesome choice for EOMA68, not least because it can do 4GB RAM. l.

CE markings
by pelzflorian (Florian Pelz) 01 Dec '16

01 Dec '16

A colleague of a friend of mine had problems getting some electronics without CE marking through customs. Let me ask just to be on the safe side: I presume the EOMA68-A20 and casings will have CE markings as appropriate? Regards, Florian
