[00:22:48] <lukas2511> silver_hook: it always depends on what exactly you want to do with it. for light use as a owncloud server for calendar / contacts sync and a few photos it will be totally fine. there probably are better options but the lime2 is a nice device to begin with
[00:26:51] <silver_hook> lukas2511: ownCloud/Nextcloud, maybe add Spreed.ME and/or an XMPP server, static HTML blog (Pelican), ZNC, maybe MediaGoblin.
[00:26:56] <silver_hook> 5-10 users max.
[00:27:52] <silver_hook> I run most of that (ownCloud, ZNC, Pelican, backups) already on a DreamPlug, so the Lime2 should be an upgrade in any case.
[00:28:26] <lukas2511> that spreed.me sounds like it may be a bit heavy on the hardware, but i'm not sure. the rest should work fine
[00:28:43] <silver_hook> I was also looking at the 96boards’ LeMaker Cello, but paying 6x the price of a Lime 2 seems a bit hefty.
[00:28:46] <silver_hook> http://www.lenovator.com/product/103.html
[00:29:32] <lukas2511> well, it's a completely different league of boards
[00:29:56] <lukas2511> take the lime2, it's a nice and cheap board
[00:32:57] <silver_hook> lukas2511: Yea, I know …I’m torn between the two. Plus with the Lime2 I could simply use a LiPo battery for a UPS.
[00:33:12] <silver_hook> (I’d still need a proper UPS for the router and modem etc., but meh)
[00:34:16] <silver_hook> lukas2511: Is the difference between the Cortex A57 and the A7 so big? Or is it something else that makes the huge difference?
[00:34:33] <silver_hook> I know that AMD Opterons are intended for proper server use, but …
[00:34:37] <lukas2511> don't know, UPS for router and modem... if power on the street is out you are offline anyway, and if it's in the house you probably are near it to reset the fuse
[00:35:44] <lukas2511> i don't really know the difference, but i think a big part of the price is the brand name of the SoC on the Cello
[00:36:10] <silver_hook> lukas2511: True …but why do you need a UPS for the board then (HDDs?)(
[00:36:31] <silver_hook> You mean, simply because it’s an AMD Opteron?
[00:36:37] <lukas2511> to detect a power outage, syncing stuff to disk and shutting down without loosing data
[00:37:03] <lukas2511> yes, i think the brand "AMD" makes a huge difference
[00:37:35] <lukas2511> also it's a bit newer (64 bit and stuff), and probably has a few very cool features that you'll probably never (can) use anyway
[00:38:04] <silver_hook> That’s what I thoght. So it’s merely that routers in general don’t store stuff to disks.
[00:38:33] <lukas2511> yup, routers mostly read from disk, and most of them only write if you change configuration
[00:38:44] <silver_hook> true true
[00:39:10] <silver_hook> Anyway, I’ll most likely go for the Lime2 … but I think someone suggested a Micro or something else for server use for some reason.
[00:39:20] <silver_hook> s/someone/someone on this channel
[00:42:26] <lukas2511> http://pastebin.com/90phCfMV ¯\_(ツ)_/¯
[00:56:16] <silver_hook> lukas2511: Thought it was you :]
[01:12:51] <silver_hook> lukas2511: And AFAICR, it was said that the Lime2 could power two 2.5" HDDs from the LiPo battery, without any issues, correct?
[01:13:58] <lukas2511> i think you don't really want to power more than one 2.5" HDD from the board
[01:34:19] <dennis_> is there already an estimate how much the olinuxino a64 will cost?
[01:39:56] <silver_hook> lukas2511: Hmmm, poopies. Then I have to have another board for backups (or external power for the backup disk)
[01:41:24] <lukas2511> couldn't you use your old dreamplug thingie as a backup system?
[01:42:16] <silver_hook> Yea, that’s another option, but that means even more stuff running :P
[01:42:22] <lukas2511> i mean you can give it a try connecting two disks to the lime2, one over usb and one over sata or something, and see if that works fine. protection on those boards is rather good so you shouldn't blow anything with that
[01:42:32] <silver_hook> But, yes, that’s the plan B.
[01:43:29] <silver_hook> lukas2511: Ideally that’s what I’d try to get, but the backup plan is running DreamPlug as simply a backup server.
[08:39:32] <azonenberg> Hi guys
[08:39:47] <azonenberg> Is Tsvetan from Olimex in this channel?
[10:41:19] <leon-anavi> morning
[10:50:50] <Tsvetan> hehe morning in 10.40 :)
[11:27:41] <leon-anavi> well... late morning :)
[14:03:46] <aleray> hi, I have an olimex a20 I bought about 2 years ago. It came with a debian image
[14:04:04] <aleray> I never really used it so far
[14:04:12] <aleray> because I couldn't boot it
[14:04:37] <aleray> today I'm trying again, this this with a screen with an hdmi adaptor
[14:04:42] <aleray> but still no luck
[14:04:56] <aleray> I have a red and a green led on, but no output
[14:07:03] <aleray> I mean no viedo output
[14:23:58] <leon-anavi> aleray, this could be a configuration issue
[14:25:01] <leon-anavi> either in script.bin (generated from FEX file) or in uenv.txt you should set screen0_output_type to type 3 for HDMI
[14:25:32] <leon-anavi> I assume that you are using Linux-sunxi kernel 3.4 and U-Boot that relies on script.bin generated from a FEX file
[14:26:16] <leon-anavi> aleray, it is a bit complicated if you do not have experience therefore I suggest you to read: http://linux-sunxi.org/Display#HDMI
[14:44:45] <aleray> leon-anavi, thanks
[14:45:08] <aleray> my main preoccupation now is to log in the system
[14:45:42] <aleray> if the screen doesn't work, is there any other means to do it? Maybe ethernet/ssh?
[14:48:04] <aleray> I should mention tha tI have the VGA adaptor and that my screen does not have native HDMI support (I'm using an adaptor)
[14:51:56] <aleray> so what you advise is to mount the system sd card and fix the boot settings right?
[14:55:11] <aleray> brb
[14:56:34] <leon-anavi> aleray, UART
[14:58:13] <leon-anavi> you need cable like this one: https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-Serial-Cable-F/
[14:59:00] <leon-anavi> read chapter 6.1.2 UART0, UEXT1, UEXT2 interface of A20-OLinuXino-Micro.pdf
[14:59:21] <leon-anavi> https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-MICRO-4GB/resources/A20-OLinuXino-Micro.pdf
[15:46:13] <aleray> leon-anavi, I managed to get a native hdmi screen. I gets a signal, but only displays a blue screen
[15:52:29] <leon-anavi> blue screen?
[15:52:43] <leon-anavi> aleray, what is your a20 board exactly and what image are you booting?
[15:52:56] <leon-anavi> are you booting it from microSD card or from NAND?
[15:53:01] <aleray> leon-anavi, when Iturn on the board the monitor catches a signal
[15:53:13] <aleray> from the microsd card
[15:53:21] <aleray> I don't know what is nand
[15:53:25] <leon-anavi> what image are you booting?
[15:53:42] <aleray> debian
[15:53:58] <leon-anavi> and what exactly is your board?
[15:54:20] <aleray> a20-olinuxino-micro
[15:54:29] <aleray> I got the micro sd from olimex
[15:54:37] <aleray> I didn't burn it myself
[15:54:53] <aleray> a20-olinuxino-micro rev E
[15:57:41] <leon-anavi> is this image configured to use HDMI as a display?
[15:57:56] <leon-anavi> it could be trying to use LCD touchscreen
[15:58:43] <aleray> leon-anavi, I don't know actually
[16:00:05] <aleray> I think this is the one I bought: https://www.olimex.com/Products/OLinuXino/A20/A20-Debian-SD/
[16:01:15] <aleray> the manual says "The default SD card setup is made with settings for HDMI 720p/50Hz."
[16:02:59] <aleray> my monitor says hdmi 720p/60Hz
[16:11:43] <aleray> I abandon for now
[16:11:51] <aleray> thanks for your help
