eoma68 router (qca9531)
by Luke Kenneth Casson Leighton 10 May '17

10 May '17

okaaay so the plan is to restart the eoma68 router project, this time with a pre-existing reference design based on the QCA9531. that has a PCIe interface, USB2 and a 5-port GbE *and* a 2x2 2.4ghz WIFI antenna. full source is available for everything so it can be entirely libre and RYF Certified. the advantage of having an EOMA68 Card in the router should be clear: the Card will have considerably more resources: RAM, CPU cycles etc. meaning that VPNs can be done without high latency, yet take advantage of the LAN capabilities of the 5-port... you could put in a MiniPCIe Card (a *proper* one) e.g. a 3G/4G/LTE Modem, WIMAX, 802.11ac... blah blah. the tricky bit: connecting the EOMA68 Card to the QCA9531. now, i took a look at the Reference Design and i *really* do not want to touch the layout for the GbE, WIFI or PCIe. so i figured, why not connect the EOMA68 USB2 host interface back-to-back with the QCA9531's USB host? turns out that something called the Cypress AN2720 can do exactly that, and it comes up as a cdc_subset of the usbnet linux kernel driver. yay! quick search online: the datasheet is publicly available, easy to find on digikey. yay! so i would assume, because it's not an actual 10/100 ethernet, that it would run at (saturate) the full 480mb/sec of USB2. so not quite GbE speeds but pretty damn close. yay! anyway should be quite straightforward. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68

Please excuse my brevity. How can you make an arm gpu for 150000usd? How would you use it? Would you put it additionally on a bord and not use the gpu located on the processor socket? If you reverse engineer the latest mali gpu, what you hold against it is, that when next version of an arm socket is for sale it will have a new mali gpu and require a new reverse engineering? Lets say 50000 people would buy the filrefly rk3399. Same people would pay 3eu each for reverse engineering the gpu. Then we would have a source code arm computer? It takes a lot of coordination to provide gnulinux distributions I assume. It is unfortunate people are not able to coordinate such that we can get source code hardware.

I saw your recent update, Luke

Just one question, I am assuming since there will be internal sd cards that your replacing one or both of the internal usbs? or am I wrong? By the way, I have a suggestion if you feel up to it, Debian 9 seems to be very close to stable, if you feel like it, and anyone wants it, install it for them. Whenever I order it, probably that will be what I will want. Using Debian 9 right now to be honest. It seems more stable then Debian 8 to me. just a thought. I wish you the best of luck, not that you will need it. :) Hoping you don't get sick again also, I am glad you will be sticking the libre guidelines. Even if it is a pain in the butt to be putting it lightly I am sure.

Laptop Power Input?
by Alexander Ross 10 May '17

10 May '17

Not sure what the power input for laptop is? 5V i think but at how many amps? I seen 3A for the cpu card... So i guess a 2.4A usb power supply won’t be suitable? Cus if it will work well from 2.4A 5V input, then i was thinking of getting this usb power supply. 6port version, really nice, efficient : https://www.mymemory.co.uk/anker-powerport-6-2-4a-usb-desktop-charger-white…

What? I own one of those and I'm almost certain that the CPU is an A7. Let's boot the PocketCHIP up... The processor is detected as an A7. I'll attach the output, it would probably be interesting to see all of it... Done, it's compressed bzip2 since it's ~300KiB decompressed which is large for an email. <aside> I'm not too clever with gpg yet, so please tell me if the compressed file is also signed (I wanted to do that so that you could be certain that it was not infected en-route like happens to MS .cab files far to frequently (even though I don't have my key signed by anyone yet \me grumble grumble)). </aside> Unless your saying that the WiFi has a built in ARM R8 (Why)? which would really surprise me considering how large the processor chip is compared with the WiFi chip. > If you look at > https://getchip.com/pages/chip > > You'll see: > On the left image the RAM (Hynix) and Wifi+BT (Realtek) and Power module > (Allwinner AXP209) > On the right the SoC (R8/A13) and NAND (Samsung) > > The A13 does not need blob's to run anymore, the WiFi+BT chip does. > AFAIKT > > Display output needs some checking in Linux and U-boot mainline.

When I first considered purchasing a PocketCHiP I read about the GPU not having 3D capabilities because of a binary blob. So, the CHIP folks hired (I think it was an extended goal of the kickstarter campaign), a kernel dev to add support to the Linux kernel for the GPU. I was going to mention this on this list before, but it's been so active... Sincerely, David

PLA stands for Poly-Lactic-Acid and if they are selling you something else you can complain, if not sue for false advertising. That's why we label things, so that we know what they are, right? So one PLA aught to be the same as any other. Aluminum is aluminum, titanium is titanium, why is PLA not PLA? I own a Reach3D printer. It's an all aluminum housing and z axis gear printer. I'm still in the construction phase, but if me and my caliper (it's auto-calibrating but I want it perfect :) work well together then I should be printing sometime around the 21st. I could help you with my printer at limited expense (unless something big happens in my life :) Also, I bought on Amazon 2 spools of PLA and one of PC. The PLA cost ~$20 per KG while the PC was ~$30. It seems to me that you might be better off with PC if finding a good PLA supplier and making a case that is not flimsy with PLA is such a problem. Sincerely, David
