Jun 23 03:08:01 <Charles_> yo\
Jun 23 03:08:24 <Guest35> Does anyone know when the Beaglebone Green will be released?
Jun 23 11:38:14 <sameer__> Hi, I'm running a Beagle Bone Black (Rev C) and am attempting to configure the SPI ports in order to read a sensor input using the board. I've followed the instructions here: http://embedded-basics.blogspot.in/2014/10/enabling-spi0-on-beaglebone-black.html, but am currently facing the following error: can't get spi mode: Inappropriate ioctl for device Aborted
Jun 23 11:38:23 <sameer__> Anyone have any ideas?
Jun 23 11:38:27 <sameer__> Thanks in advace
Jun 23 11:38:55 <sameer__> (^?? I'm still here)
Jun 23 11:40:45 <tbr> and which distribution are you running on your BBB?
Jun 23 11:43:11 <sameer__> Debian 3.8.13-bone70
Jun 23 11:44:37 <tbr> so what on that page have you actually done successfully?
Jun 23 11:44:44 <Abhishek_> sameer__: config-pin overlay BB-SPIDEV0 ?
Jun 23 11:46:35 <sameer__> Successfully executed most of the commands on that page. The code (spi_test.c) compiles and runs as well, but there's an if/else case within that program that is configured to return the above error, and that's what's happening.
Jun 23 11:47:55 <sameer__> @Abishek_ Yeah, finished with all that.
Jun 23 11:56:09 <tbr> sameer__: and the spidev shows up?
Jun 23 12:00:43 <sameer__> yes
Jun 23 12:00:49 <sameer__> spidev 1.0
Jun 23 20:58:43 <cristos> Hello
Jun 23 21:00:28 <cristos> Is BeagleBoard open enough to make a complete embedded programming board - i.e. open boot rom, u-boot ?
Jun 23 21:02:46 <ww> sadly i don't think so because of the blob for the gpu
Jun 23 21:03:18 <ww> if i'm not mistaken the chip won't run without it, even if you don't use it
Jun 23 21:03:33 <ww> same story as pi
Jun 23 21:03:39 <myself> did I trip over something and land in #raspberrypi?
Jun 23 21:04:04 * ww might be spreading misinformation and would be glad to be corrected
Jun 23 21:04:55 <cristos> ww: ok, thanks
Jun 23 21:05:13 <myself> Boot process here: http://www.twam.info/hardware/beaglebone-black/u-boot-on-beaglebone-black
Jun 23 21:05:17 <myself> no blobs
Jun 23 21:06:08 <_av500_> cristos: the boot rom is not open
Jun 23 21:06:11 <_av500_> but its a ROM
Jun 23 21:06:13 * ww is glad
Jun 23 21:06:15 <_av500_> burned into the chip
Jun 23 21:06:29 <_av500_> it happily loads you code
Jun 23 21:06:33 <_av500_> that
Jun 23 21:06:36 <_av500_> sits whole purpose
Jun 23 21:06:43 <_av500_> that's its
Jun 23 21:07:08 <cristos> what about chip initialization? Is it done by the Boot ROM or later, by the u-boot?
Jun 23 21:08:28 <myself> I wonder if the standard "Read the SRM" advice applies here. Almost everything is in the SRM.
Jun 23 21:08:45 <stt_michael> depends what you mean by 'initialisation' ...
Jun 23 21:08:53 <_av500_> cristos: the boot rom just sets up enough to be able to load the boot loader
Jun 23 21:09:03 <stt_michael> peripheral is done downstream even of uboot
Jun 23 21:09:06 <_av500_> e.g. for usb boot it has to enable usb etc
Jun 23 21:09:15 <_av500_> or network boot
Jun 23 21:10:17 <_av500_> the boot rom hands control over to your code
Jun 23 21:10:24 <_av500_> then you can do as you please
Jun 23 21:10:52 <cristos> so, for making a complete, customized embedded environment based on u-boot and linux (for self-educational purposes ;) ), is the BB a good solution?
Jun 23 21:10:58 <_av500_> yes
Jun 23 21:11:11 <_av500_> isnt the BBB uboot and linux already?
Jun 23 21:11:17 <stt_michael> o,O
Jun 23 21:11:45 <myself> yeah but that's not as educational as bricking your board and then recovering it with a pencil, eight paperclips, and a wad of chewing gum!
Jun 23 21:11:53 <stt_michael> :)
Jun 23 21:12:15 <cristos> myself, :) that was my next question, what if I brick it :) ?
Jun 23 21:12:26 <_av500_> you cant
Jun 23 21:12:36 <myself> you'd need to damage hardware to render it unbootable.
Jun 23 21:12:42 <_av500_> you cannot overwrite the boot ROM
Jun 23 21:12:44 <_av500_> its a ROM
Jun 23 21:12:57 <myself> there's actually no such thing as a brick here, the boot is ROM, and if you hose the emmc, you just pop in a microSD card.
Jun 23 21:13:07 <_av500_> or boot from serial
Jun 23 21:13:09 <_av500_> or from usb
Jun 23 21:13:12 <_av500_> or from network
Jun 23 21:13:12 <myself> so, step 1, cut a hole in the emmc ;)
Jun 23 21:13:30 <myself> I mean if education comes from pain
Jun 23 21:13:30 <cristos> thanks :)
Jun 23 21:13:47 <stt_michael> unless you fry the processor
Jun 23 21:13:51 <myself> I dunno, the bbb might be too robust for this
Jun 23 21:14:06 <stt_michael> just connect the io pins to 5v .. you'll be fine... :D
Jun 23 21:14:14 <cristos> :D
Jun 23 21:14:18 <myself> wait what?
Jun 23 21:14:29 <myself> I thought it ran on 24, like all industrial electronics!
Jun 23 21:14:33 <_av500_> 24?
Jun 23 21:14:37 <myself> Is that why it smelled funny?
Jun 23 21:14:38 <cristos> not 240VAC ? :(
Jun 23 21:14:38 <_av500_> thats for sissies
Jun 23 21:14:39 <stt_michael> myself, .. i'd like to see it on 24 ..
Jun 23 21:14:44 <cristos> :D
Jun 23 21:15:06 <stt_michael> there'd definitely be 'magic smoke' if you got to 415 or above ..
Jun 23 21:15:28 <cristos> and all electrons will evaporate with that smoke, right ;) ?
Jun 23 21:15:29 <myself> I can make 480 at significant amps, 15kv at less..
Jun 23 21:15:41 <myself> no no
Jun 23 21:16:04 <myself> I think the next dumb experiment is gonna involve the liquid nitrogen dewar and an offboard clock generator
Jun 23 21:16:04 <stt_michael> but we'd have to report you to beaglebone abusers anonymous ...
Jun 23 21:16:19 <myself> putting the bogo in bogomips1
Jun 23 21:16:21 <myself> !
Jun 23 21:16:22 <stt_michael> or BBAA
Jun 23 21:16:30 <myself> select start?
Jun 23 21:16:54 <cristos> so, to summarize, it is (virtually) unbrickable by the (ab)user, right /
Jun 23 21:16:55 <cristos> ?
Jun 23 21:17:04 <myself> completely, literally, unbrickable
Jun 23 21:17:11 <cristos> good :)
Jun 23 21:17:16 <myself> if you've rendered your board unbootable, you've done it by hardware damage
Jun 23 21:17:37 <cristos> so, any tinkering is possible, unless I fry the board
Jun 23 21:17:39 <cristos> right ?
Jun 23 21:19:16 <myself> how many more times do you want us to say yes?
Jun 23 21:19:47 <stt_michael> just friggin get one and play with it ffs...
Jun 23 21:20:36 <myself> I prefer jffs2 personally, but suit yourself
Jun 23 21:20:53 <cristos> thanks
Jun 23 21:21:18 <cristos> didn't mean to upset you, just doing a pre-shopping research
Jun 23 21:21:54 <myself> nah, not upset, just... I think the only board with a more robustly documented boot process is probably the altair :P
Jun 23 21:22:53 <myself> read the SRM, get a console cable if you don't already have a 3v3 ttl serial adapter sitting around..
Jun 23 21:22:58 <myself> and go nuts
Jun 23 21:23:27 <stt_michael> +1 myself
Jun 23 21:23:58 <_av500_> what kind of nuts?
Jun 23 21:24:05 * _av500_ is allergic to almonds
Jun 23 21:24:52 <myself> deeeeeeez...
Jun 23 21:24:56 <stt_michael> peanuts ofc .. or cashews
Jun 23 21:25:11 <cristos> my personal favourites are brazil nuts, btw ;)
Jun 23 21:25:23 <myself> I like other brazilian things
Jun 23 21:25:37 <myself> o:)
Jun 23 21:25:55 <cristos> yeah, like brazillian depilation ;)
Jun 23 21:27:01 <cristos> thanks for your help
Jun 23 23:47:17 <Hreikin88> does anyone know if xbmc will work on the beagleboard xm using arch linux ?
Jun 23 23:53:19 <Hreikin88> iv seen the GSoC for angstrom i was just wanting to know if anybody had tried it on arch
Jun 24 00:58:35 <Laotse1976> Greetings. Any one from Italy here? I need some help on where to buy the beaglebone in Milan or Bologna.
Jun 24 01:00:39 <Laotse1976> More precisely: Reliable physical stores.
