[02:09:02] <adj_> koz_, not box for A64
[02:09:52] <koz_> adj_: That's a bit unfortunate. I guess I can get a LIME instead.
[02:12:00] <adj_> koz_, In my opinion A20-Lime and A20-Lime2 are better options that A64
[04:16:11] <koz_> adj_: Why do you think so?
[04:17:36] <adj_> allwinner a20 has much better mainline support
[04:18:18] <adj_> koz_, http://linux-sunxi.org/Linux_mainlining_effort
[04:18:36] <koz_> adj_: Ah, OK.
[04:18:46] <koz_> Well, that gives me even more reason to get that one instead. Thanks!
[04:19:16] <adj_> lime2 has gigabit ethernet, if that is important for you
[04:19:22] <adj_> and also 1GB of RAM
[04:19:27] <koz_> Those are both very important.
[04:19:32] <koz_> Hence why I'd get a Lime2.
[04:19:43] <adj_> nice
[04:19:47] <adj_> :)
[04:19:51] <koz_> Also, another question: if I have four Lime2s, I'd need to plug in four things. Is there any way to run them off a single PSU of some kind?
[04:19:55] <koz_> I have no idea about these things.
[04:20:44] <adj_> it could be done
[04:21:23] <koz_> Is it easy or worth doing?
[04:22:43] <adj_> koz_, have you already bought it?
[04:22:51] <koz_> Not yet - I'm considering my options.
[04:23:12] <koz_> I wanted to ask here because probably someone here knows this stuff better than me.
[04:23:19] <adj_> I suggest not buying the 4GB NAND version, but without it
[04:23:32] <adj_> the emmc version is OK
[04:23:48] <adj_> there is no NAND mainline support
[04:23:58] <koz_> eMMC is OK though, right?
[04:24:14] <adj_> yes, emmc is like sdcard
[04:24:45] <adj_> the NAND support in old allwinner kernel is very bad, I don't recommend it
[04:24:54] <koz_> OK, makes sense.
[04:25:06] <adj_> look at linux-sunxi.com for more information
[04:25:14] <koz_> I will - it's a very useful resource.
[04:25:30] <koz_> But anyway, about the power supply - would you recommend me doing this, and if so, what should I get?
[04:25:37] <adj_> in fact there is support for NAND in mainline, but only for SLC NAND
[04:25:49] <koz_> I will keep that in mind.
[04:25:52] <adj_> but all boards use MLC NAND
[04:26:40] <adj_> I use an old plastic box for lime2, but new metal boxes should be better
[04:26:53] <koz_> I was going to use the one Olimex sells.
[04:27:22] <adj_> yes, the metal one, they previously sold a plastic one (that was also OK, but metal is better)
[04:27:40] <adj_> for software, armbian is very nice
[04:27:56] <koz_> I'm sorted for software, don't worry. :)
[04:28:03] <koz_> That's the part I _do_ understand.
[04:28:09] <koz_> The hardware part not so much.
[04:29:18] <adj_> by the way, I think that lime/lime2 are 5V only, DON'T connect anything higher
[04:29:25] <koz_> I wasn't planning on it.
[04:29:35] <koz_> But anyway, what could I use to power them instead of mains?
[04:29:50] <koz_> I've seen some of the power supplies Olimex sell, but I have no idea how I'd use them, or if they're the right ones.
[04:29:56] <koz_> I basically want something that can power four Lime2s.
[04:30:02] <adj_> I mean that olimex sells other power supplies with higher voltage, be careful
[04:31:05] <adj_> the right one is this one:https://www.olimex.com/Products/Power/SY0605E/
[04:31:24] <adj_> have fun!
[04:31:44] <koz_> I plan to.
[04:43:53] <koz_> If I power the Lime2 via OTG, will it have enough juice to run a SATA SSD connected to it?
[05:26:05] <adj_> koz_, read the lime2 manual, it recommends the external barrel connector if devices are connected
[05:26:43] <lukas2511> wasn't otg power limited (to 500mA)?
[05:28:52] <adj_> lukas2511, do you mean the OTG standard? I don't think so, and if true many devices allow much more current
[05:29:14] <lukas2511> no i mean in that exact configuration
[05:29:34] <adj_> that's probably the case
[05:29:48] <adj_> the power connector is recommended anyway
[05:29:55] <lukas2511> "The USB_OTG features Low Loss Power Distribution Switch SY6280 which protects the board in case
[05:29:57] <lukas2511> the devices you have plugged to the USB_OTG attempt to draw more current than 523mA combined. The
[05:29:59] <lukas2511> maximum current available on the 5V USB_OTG is exactly 523mA
[05:30:01] <lukas2511> "
[05:30:12] <lukas2511> oh no sorry
[05:30:14] <lukas2511> wrong direction
[05:31:10] <lukas2511> maybe i'm remembering that incorrectly
[05:31:26] <adj_> lukas2511, I also remember something like that
[05:31:47] <adj_> long story short, koz_ use the power connector
[05:32:33] <adj_> also, you can use a mechanical HDD, but only low power ones that don't need 12V supply
[05:32:35] <lukas2511> koz_: you can get usb to barrel connector cables cheaply, if you have a usb power supply those would be the perfect solution
[05:34:09] <adj_> if I remember correctly, it's positive inside barrel (the normal way)
[05:37:52] <lukas2511> http://linux-sunxi.org/AXP209#REG_30H:_VBUS-IPSOUT_channel_management
[05:38:02] <lukas2511> yea it's limited to 900mA by default
[05:38:21] <lukas2511> the limit can be disabled but you'd have to power up for that to work
[05:38:34] <lukas2511> so, it's not really a good idea
[05:39:55] <lukas2511> but this axp209 information is weird to read, it looks like an output, but it seems to be the output current that can be supplied on the output while being powered via vbus.. i dont know, i wouldn't trust it :D
[08:34:54] <jo0nas> I have "empirical evidence" that if you use the LIME2 board with a broken power supply labeled as providing 5V but in fact providing 10V, then you will have a room smelling of melted power plug after ~15 minutes
[08:35:18] <jo0nas> ...so don't do that - stick to 5V :-/
[09:08:37] <koz_> lukas2511: I have a 5V2.4A 5-port USB hub. Would that + USB-to-barrel connectors be OK?
[09:36:35] <leon-anavi> morning
[15:43:05] <adj_> koz_, power specifications are important but power quality also is
[15:44:54] <adj_> I have a powered 4 port USB switch that provides a very noisy power
[15:45:45] <adj_> so badly that the smartphone touch screen didn't worked and an external USB keyboard sends but key codes
[15:47:07] <adj_> bad key codes
[21:50:55] <koz_> adj_: This USB hub's pretty good power-wise. Haven't had any issues with power stability from it.

[01:13:08] <koz_> I'm interested in the A64 devices, but I noticed there's no case for them. Is this right, or am I missing something?[02:09:02] <adj_> koz_, not box for A64
