**** BEGIN LOGGING AT Wed Sep 25 02:59:59 2013 Sep 25 03:04:40 is that German? Sep 25 05:11:43 Anyone had good luck with the pruss on bbb on v3.8 kernel? Sep 25 05:12:01 I have code that triggers IRQs in the PRU firmware Sep 25 05:12:24 I have a kernel module that did irq_request for the given host IRQ Sep 25 05:12:26 but it never fires Sep 25 05:12:33 used to work on the v3.2 kernel Sep 25 05:12:43 I suspect some kernel IRQ stuff changed rather then the PRU itself Sep 25 05:12:55 cat /proc/interrupts shows my IRQ with 0 count Sep 25 05:20:11 Hello Sep 25 05:20:22 I have a question about GPIO in beaglebone Sep 25 05:20:50 Is there anyway to read or write 32 bit or 8 bit with GPIO Sep 25 05:20:58 instead of only 0 or 1 Sep 25 05:21:16 thanks Sep 25 05:23:45 kitarousa: not that I'm aware of, not using the kernel's gpiolib at least Sep 25 05:24:20 The GPIO hw registers would let you set/clr multiple bits in a single write, but I don't think you can do that without hacking it Sep 25 05:24:31 and assuming they are on the same GPIO bank Sep 25 05:24:48 could you memory map the gpio registers and do it that way? Sep 25 05:25:26 I have not tried memory map Sep 25 05:25:27 magyarm: you could open /dev/mem and do that, but now you're doing stuff behind the kernel's back (aka hack) Sep 25 05:27:35 if hacking it is ok, the starterware will probably help: http://processors.wiki.ti.com/index.php/StarterWare Sep 25 05:27:58 If you're running starterware you're probably in better shape Sep 25 05:28:22 would it possible to write your own kernel module that does the memory map access to gpio ports? Sep 25 05:28:25 Or you could use the PRU, but that's a big task Sep 25 05:28:44 magyarm: gpiolib in the kernel manges the gpios for all SOCs, and it doesn't support what you want to do Sep 25 05:28:55 so you'd still ahve to hack around behind gpiolib's back Sep 25 05:29:22 Checkout https://www.kernel.org/doc/Documentation/gpio.txt Sep 25 05:29:25 maybe hacking is only choice Sep 25 05:29:38 I have read the GPIO kernel documentation Sep 25 05:29:48 it just support 0 and 1 Sep 25 05:29:51 Potentially Sep 25 05:30:14 The more "proper" approach might be to modify gpiolib to let you set contiguous blocks like you want to do Sep 25 05:30:23 toobluesc I know, just thinking out loud about ways to do port writes Sep 25 05:31:50 if a gpio isn't exported, will gpiolib still manage it? Sep 25 05:32:41 If you were to do it in kernel and directly access the ports, at least do the (devm_/pinctrl_)_gpio_request() so you can be sure that nobody else is using the GPIOs you are messing with, nor are they going to request and use them later Sep 25 05:32:53 gpiolib manges _all_ gpios for a SOC Sep 25 05:36:54 kitarousa: are you trying to bit bang something? Sep 25 05:37:17 so after gpiolib requests are run so they can't be called on later, why not then memory map the gpio bank register you want and do byte size (or greater) writes? I'm coming from a more microcontroller background, and teaching myself more the embedded linux side, so apologies if the question is silly Sep 25 05:39:08 magyarm: that's what i was suggesting as the most reasonable hack that's pretty safe Sep 25 05:39:42 as long as you request them from gpio lib you know that no other code is using them now or int he future, so then it's pretty safe to modify them Sep 25 05:40:02 just make sure you use SET_DATAOUT and CLEAR_DATAOUT so you don't clobber adjacent bits Sep 25 05:40:20 the part that is a hack is that you're still doing stuff behind gpiolib's back, but it should be pretty safe at that point. Sep 25 05:41:22 toobluesc: that makes sense. thank you for explaining Sep 25 05:41:55 magyarm: another idea might be to use the PRU's gpios Sep 25 05:42:12 no kernel modules manage those after you switch the pinmux Sep 25 05:42:31 then you could do a userspace PRU firmware that could do what you want on the PRU core Sep 25 05:44:18 the PRU has been on my list of things to learn. Sounds like a fun project to do so. I don't actually have an application for any of this right now, just jumped on kitarousa 's question since it sounded interesting to me Sep 25 05:46:00 looks like the PRU has 16 GPIOs that are directly accessible by it Sep 25 05:46:13 The PRU is a blessing and a curse :) Sep 25 05:48:52 now if only I could figure out why my interrupt controller is semi broken Sep 25 05:58:05 greetings earthlings Sep 25 06:00:26 hi Sep 25 06:00:46 It appear something in the kernel is INTC_MIR0 Sep 25 06:00:57 messing with INTC_MIR0 * Sep 25 06:20:22 morn Sep 25 06:20:41 magyarm, toobluesc, thanks for your answer Sep 25 06:20:41 evenin' Sep 25 06:20:50 kitarousa: np, good luck! Sep 25 06:20:52 I will take a look on PRU Sep 25 06:21:19 if you are trying to bitbang a parallel interface the PRU is probably the best tool, but painful to get going Sep 25 07:00:56 helloo.....from where can i get cross compiler for my BBB...I am using Ubuntu 11.04 in my PC... Sep 25 07:01:50 fgf: what buildsystem do you use? Sep 25 07:02:12 buildsystem means...??? Sep 25 07:02:14 fgf: if you use buildroot, angström or the like, they come with their own cross compiler Sep 25 07:02:54 are there A9 or dual core cpu's on the ti roadmap or is that all dead? Sep 25 07:04:29 octacore Sep 25 07:04:36 keesj: ask your friendly TI sales person Sep 25 07:05:14 I don'have any Sep 25 07:05:25 keesj: then find one using ti.com Sep 25 07:05:29 keesj: there is a list of them Sep 25 07:05:36 you are all I have Sep 25 07:05:55 now, calling me a sales person is a major insult! Sep 25 07:05:59 (and want) Sep 25 07:06:11 sorry dude, but i dont swing that way Sep 25 07:06:56 it is not such a weird question. I guess I can ask "is there going to be a dual core beagle?" Sep 25 07:07:16 or "shall we make one?" Sep 25 07:07:21 make one Sep 25 07:49:12 keesj: ask tom flanagan Sep 25 07:51:36 k Sep 25 08:15:27 Hi All Sep 25 08:15:55 Could u send me the MSP430 + Camera compitable board Sep 25 08:16:01 who know how can i fix validate error Sep 25 08:16:25 what? Sep 25 08:40:28 i want .iso file of angstrom OS Sep 25 08:40:36 where can i get it? Sep 25 08:41:25 iso? what for? Sep 25 08:41:29 we do not do isos, they only get waretized and people spread them through piratebay. Sep 25 08:41:54 I'm going to buy beagle bone black but it is going to take time so to try it on vmware i need iso file of angstrom Sep 25 08:42:24 *facepalm* Sep 25 08:42:34 vin_: vmware for ARM? Sep 25 08:42:36 * vvu|Log hides a bit Sep 25 08:42:37 you have that? Sep 25 08:42:44 vin_: you cannot *emulate* a BBB in vmware/vbox/whatever Sep 25 08:42:58 can qemu help?? Sep 25 08:42:58 or no, that should be Sep 25 08:43:04 vin_: not really Sep 25 08:43:07 vin_: *you* cannot emulate a BBB in vmware/vbox/whatever Sep 25 08:43:43 so even qemu can not emulate BBB Sep 25 08:43:49 that is u are saying?? Sep 25 08:43:57 correct Sep 25 08:44:01 and what for Sep 25 08:44:11 i have no idea what "u" is saying, i do not know that nickname. Sep 25 08:44:26 the best way to emulate a BBB is to just buy one, real emulation :) Sep 25 08:45:08 k thnak you Sep 25 08:48:48 xD Sep 25 09:55:19 hey beaglers Sep 25 09:55:35 someone has a idea on this one? http://askubuntu.com/questions/349775/how-to-make-a-gpio-pin-act-like-pc-speaker-positive Sep 25 10:17:27 what you wrote there Sep 25 10:17:30 try that Sep 25 10:18:11 though on a PC, the speaker is not jsut a GPIO Sep 25 10:18:16 I think there is some timer hardware too Sep 25 10:18:26 so just the speaker driver might not work Sep 25 10:32:47 hy av500 again Sep 25 10:34:17 i got it wo work without any transitor with just 3,3V and its very loud ;) Sep 25 10:36:03 fine Sep 25 10:36:10 if the GPIO breaks, you know why Sep 25 10:36:32 did not know about time hardware. so i guess i have to create my own timer software to make some sounds. Sep 25 10:36:41 it can break? with that? Sep 25 10:36:53 with your setup Sep 25 10:37:01 does it matter what ends up in GRD? Sep 25 10:37:24 GRD? Sep 25 10:37:58 i have it in P8.10 and GRD Sep 25 10:38:06 or what its called? Sep 25 10:38:15 i thaught its for ground Sep 25 10:38:22 GND Sep 25 10:38:53 oh yes Sep 25 10:38:56 GND Sep 25 10:39:42 so it the 3,3 V whatever ampere/corrent go from the P8.10 into GRD that could break my BBB? Sep 25 10:39:53 current* Sep 25 10:41:25 it i would just mut a cable between those 2 without the speaker, and then same question for with speaker. i really have no idea of hardware. but I tought it fine this way. Sep 25 10:41:45 as I said Sep 25 10:41:49 if i would just put* ... Sep 25 10:41:52 you draw too much current from the GPIO Sep 25 10:41:55 use a transistor Sep 25 10:41:59 its all explain on the web Sep 25 10:42:04 at many places Sep 25 10:42:08 or ignore it Sep 25 10:42:11 ok thanks Sep 25 10:42:16 good to know ;) Sep 25 10:42:17 basic electronics can also be learned there Sep 25 10:43:05 i am just so unpatient, i saw this guy who did somethign liek that with the rasberry pie and it looked like he did not use a transitor so i assumed its ok Sep 25 10:43:53 don't come crying here when you burn out the processor Sep 25 10:44:01 but even if the pie might be different Sep 25 10:44:22 the problem with the piers is that they're clueless Sep 25 10:45:08 i dont like when ppl say untrue things about groups of ppl Sep 25 10:45:26 what's untrue? Sep 25 10:45:33 maybe 80% if them are clueless, maybe. still then the statement is wrong. Sep 25 10:45:41 fine Sep 25 10:45:43 you dont call a group clueless Sep 25 10:45:48 mostly clueless then Sep 25 10:46:14 ok i am to but when it comes to byuing stuff i am not Sep 25 10:46:32 never said they are clueless about buying stuff Sep 25 10:46:40 and the bbb is so much better in terms of hardware Sep 25 10:46:42 they're clueless about electronics and embedded linux Sep 25 10:46:59 i did not accuse you of saying that i am Sep 25 10:47:24 whatever - don't take seriously whatever is said on irc Sep 25 10:47:29 i saw some other board thats even better in hardware ... forgot the name Sep 25 10:47:47 its 10ā‚¬ more with sata and 2 usa 4gb nand and 1gig ram Sep 25 10:48:04 and am a bit unhappy that i not baught that, was a but to late Sep 25 10:48:34 cubieboard? Sep 25 10:49:27 cubieboard2? Sep 25 10:49:41 yes Sep 25 10:50:06 is the sata and network on the cubieboard through USB? Sep 25 10:50:27 with adapter? Sep 25 10:50:45 it directly on the board if thats whats you asking Sep 25 10:51:08 be most important think is that it has 1gig ram Sep 25 10:51:22 you can build a serious server with that Sep 25 10:51:43 i actaully could send my bbb black and buy one ;) Sep 25 10:51:44 lol Sep 25 10:52:01 no, I know some boards use a usb to communicate to on-board sata/ethernet. just don't know how th cubieboard does it Sep 25 10:52:30 there is still time i have the right to send it back without 14 days without a reason Sep 25 10:52:46 By default the pin 27 on header P8 on BBB is coming with a function LCD_VSYNC...i want to change it to a GPIO(MODE 7).....How can i do this.....?? Sep 25 10:52:47 redanimalwar: the IFC6410 is a lot more expensive, but looks good for server-purposes as well Sep 25 10:53:23 By default the pin 27 on header P8 on BBB is coming with a function LCD_VSYNC...i want to change it to a GPIO(MODE 7).....How can i do this.....?? Sep 25 10:53:53 i guess i will stay with bbb the community is bigger i guess. also I learned my share about it already Sep 25 10:55:17 By default the pin 27 on header P8 on BBB is coming with a function LCD_VSYNC...i want to change it to a GPIO(MODE 7).....How can i do this.....?? Sep 25 10:55:26 ok i need to buy a transistor, but wich one ) the same they use for the LED? Sep 25 10:55:57 daaw did somebody join this chat sinde you first ask? Sep 25 10:56:02 ..ed Sep 25 10:56:12 since* Sep 25 10:56:22 no Sep 25 10:56:28 ok then stop spamming Sep 25 10:56:47 then you say it Sep 25 10:57:39 lol how old are you? Sep 25 10:58:00 i am a totally noob i cant help you with that Sep 25 10:58:12 why you want to know..? Sep 25 10:58:39 just curious Sep 25 10:58:41 from where can i get the information.. Sep 25 10:58:46 i am 24 Sep 25 10:58:51 you..?? Sep 25 10:59:41 30 Sep 25 10:59:57 from.? Sep 25 11:00:53 but with 24 i knew already that pasting questions twice is not helping myself ;) Sep 25 11:00:55 germany Sep 25 11:01:28 daaw: http://elinux.org/BeagleBone_and_the_3.8_Kernel Sep 25 11:01:30 mm... Sep 25 11:01:36 read that Sep 25 11:01:46 ok av500..thanks Sep 25 11:27:23 redanimalwar: what server do you want to set up using your BBB? Sep 25 11:31:07 mailserver Sep 25 11:31:16 atm, maybe more later Sep 25 11:31:38 should be fine for just myself Sep 25 11:46:03 redanimalwar: yes, the BBB should definately be able to do a personal mail server. I actually tested it with SOGo as addition as well and a simple Zotonic blog, and it was able to cope just fine with a (low of course, but normal) load Sep 25 11:51:51 CPU runs SW, film at 11 Sep 25 11:54:20 av500: whoa! Sep 25 11:54:52 yes Sep 25 11:54:59 surprises me every day anew Sep 25 11:56:33 * LetoThe2nd just got totally blasted. Sep 25 12:01:25 and what does SW and film at 11 mean? Sep 25 12:01:55 software Sep 25 12:03:10 Film at 11 originated when news programs would advertise they were going to run a more detailed piece later in the night Sep 25 12:03:42 http://en.wikipedia.org/wiki/Film_at_11 Sep 25 12:09:31 in case someone was bored with ARM || MIPS :) https://www.turris.cz/en/hardware Sep 25 12:10:28 system is systemd free (tm) Sep 25 12:12:36 open source hardware, thats cool Sep 25 12:14:36 nothing about price, will be pretty expesice i guess Sep 25 12:15:29 that's relative :) Sep 25 12:15:36 redanimalwar: it means that a mail server is going to run on about any hw platform these days Sep 25 12:15:46 that runs linux Sep 25 12:16:31 some joke i not get because i am german, yes i got that somehow after the link Sep 25 12:17:33 redanimalwar: please stop blaming every thing that you do not understand on being german - you're just ruining it for every german who understands it. Sep 25 12:18:02 ynezz: why not use a open-source SPARC design and improve on it? Sep 25 12:19:06 http://www.oracle.com/technetwork/systems/opensparc/index.html Sep 25 12:19:29 blaaa: well, I'm not involved in this project Sep 25 12:19:35 well if i run a iRedmail wich is like 10 programs meld together for a serious mailserver with antispam, antivirus and all that stuff i would argue that i woudl struggle hard on machines that run linux what have only 64mb ram or whatever is the min for linux Sep 25 12:19:43 blaaa: and it's probably too late now :) Sep 25 12:20:34 and Oracle, ehm Sep 25 12:21:03 ynezz: yes, probably. Also it would be much more difficut and expensive I suppose. But it would be completely open source hardware, if someone designs suitable controller chips in addition... Sep 25 12:21:24 ynezz: I think sun has released the stuff... Sep 25 12:21:38 and "complete opensource hardware" wasn't the goal either Sep 25 12:22:18 it's quite hard anyway, as there's WiFi involved also Sep 25 12:22:49 ynezz: yes, pantents (and the amount of work) won't mke that easy... Sep 25 12:24:13 Leto: STFU I did not "blame" anything im me beeing german, i simply stated the fact, things like jokes and stuff that nobody everybody here refers to "spannung" in ampere and not current so i did not know about it. I would probably get that "11 on film" joke if I would live in the US that a simple true statment not "blaming" anthing. Sep 25 12:25:50 redanimalwar: a very mature answer indeed. Sep 25 12:25:54 *plonk* Sep 25 12:26:43 its quote common that you understand a foreign language pritty well but when it comes to spcific jokes and stuff and you have no relationship to that area you will not get them. the fact that the wikipedia page is not even translated on ANY language proves my point! Sep 25 12:28:26 but now i am not mature because i have the arguments where you have nothing but bs? sure typical Sep 25 12:28:58 for the protocol: i will not discuss with anybody opening an argument with "STFU" Sep 25 12:29:45 yeah how about you stop talk to me at all idiot ( to be mature one time) Sep 25 12:30:28 * georgem puts on his fire suit Sep 25 12:31:01 georgem: why? better use a stillsuit Sep 25 12:31:34 heh Sep 25 12:31:48 * vvu|Log thinks we all need to hide a bit Sep 25 12:32:04 i am simply right and you clain i blame "everything on beeing german" while all i did was stating that about TWO area specific things. so why you are start arguing with respect? when you want to insult me Sep 25 12:32:33 let'S just stop Sep 25 12:36:01 and remember the first rule of IRC - if you dont understand something, go google it Sep 25 12:36:16 And pretend you understood it Sep 25 12:36:22 exactly Sep 25 12:36:28 nothing to pretend Sep 25 12:36:37 you google it, you read, you understand Sep 25 12:36:37 well.. yeah Sep 25 12:36:45 make for far less "fill noise" Sep 25 12:36:48 makes Sep 25 12:37:57 problem because i stated another fact, that its stupic to call a group "idiots" when some of them are. ppl are ofended by the truth its always the same. they can factit so they come up with bs. Sep 25 12:38:25 as far as I can remember you started calling people idiot Sep 25 12:38:28 av500: just got the BBxM! found somebody in my university who is selling one Sep 25 12:38:29 but as said, stop Sep 25 12:38:49 i pretended to get it? Thats why a asked what it mean, said nothing untill i was asked about it and then said "i SOMEHOW got that it was a joke" Sep 25 12:38:53 is the last one Rev C Sep 25 12:38:59 FFS stop spreading BULLSHIT Sep 25 12:39:26 redanimalwar: Did you forget to take your medication? Sep 25 12:40:03 i not need any medication, 90% of medication is bad and invented to make big pharma rich Sep 25 12:40:11 right.... Sep 25 12:40:37 and i am so healthy that i not need something form the 10%, but thanks for asking Sep 25 12:40:56 plonk Sep 25 12:41:06 Is ther a KIND sould that can help me getting some commands run at boot time? distri ubuntu Sep 25 12:41:32 the usual ubuntu way? Sep 25 12:41:50 Bo_DK: in trivial cases, just /etc/rc.local it Sep 25 12:43:49 if your intersted in big pharma you should watch this http://blip.tv/azk/azk-vortrag-nebenwirkung-tod-korruption-in-der-pharmaindustrie-john-rengen-1828414 its english (the actual talk) Sep 25 12:44:37 no KIND souls to help out with a few commands etc? Sep 25 12:45:51 [14:41] Bo_DK: in trivial cases, just /etc/rc.local it Sep 25 12:46:10 https://www.google.de/search?q=ubuntu+run+command+at+startup Sep 25 12:46:18 https://www.google.de/search?q=ubuntu+run+command+at+boot Sep 25 12:46:20 some commands? Sep 25 12:46:21 https://www.google.de/search?q=ubuntu+run+command+at+login Sep 25 12:47:00 funny thing that i hate it when ppl just say "google it" but in this case its you maybe really should ;) Sep 25 12:47:52 if your running kde you can easy setup starting scripts without ever touching eny special files for that, just in setting. no idea about gnome Sep 25 12:49:26 i have these 3 commands in rc.local...: Sep 25 12:49:35 1. chmod 666 /sys/devices/bone_capemgr.9/slots Sep 25 12:49:46 2. echo ttyO1_armhf.com > /sys/devices/bone_capemgr*/slots Sep 25 12:49:51 Bo_DK: i usually do stuff in my crontab as an user Sep 25 12:49:58 there are aboout 3 or more places for starting scripts Sep 25 12:50:05 if i want commands at startup Sep 25 12:50:18 3. gpsd /dev/ttyO1 Sep 25 12:50:20 vvu|Log: well thats more like anacron then. Sep 25 12:50:23 2 does not work Sep 25 12:50:28 not sure if rc.local works for ubunut, i remember tampering with that shit once Sep 25 12:51:22 it may also matter when exacty you want them to run and if they need root rights Sep 25 12:51:28 there are also services Sep 25 12:51:43 this init.d/ stuff Sep 25 12:51:56 funny thing is Sep 25 12:51:58 you can set them up to start at boot as root Sep 25 12:52:12 if i log in to terminal and do those one at a time they work Sep 25 12:52:22 just not from anywhere else.... so far Sep 25 12:57:02 no help? Sep 25 12:57:54 http://askubuntu.com/questions/814/how-to-run-scripts-on-start-up Sep 25 12:58:05 70 upvotes look cedible Sep 25 12:58:13 trustable i mean Sep 25 12:59:06 well allready been tried Sep 25 12:59:16 well i should better refer to the 31 upvotes on the answer, thats what matters ;) Sep 25 12:59:18 but why not again just for the fun of it Sep 25 13:00:02 but that what i told you Sep 25 13:00:10 upstart/services Sep 25 13:00:27 the new thing here is how to setup this in the gui Sep 25 13:00:50 but again it depends on what exact stage and root Sep 25 13:00:59 what gui? i run terminal Sep 25 13:01:03 no screen to BBB Sep 25 13:01:14 well Sep 25 13:01:22 Q: Sep 25 13:01:43 why does one command work from terminal when i do it by hand Sep 25 13:01:48 but not from rc.local Sep 25 13:02:14 well i would try a upstart script Sep 25 13:02:18 did you do thatĆ Sep 25 13:02:45 srew your rc.local now. remove eveything you added. Sep 25 13:02:50 would like to know answer to my Q..... Sep 25 13:03:15 why can it all work when i type my commands by hand Sep 25 13:03:25 did you try upstart script? Sep 25 13:03:29 but not when they are run at boot time Sep 25 13:03:34 you can do this without GUI! Sep 25 13:03:55 and why do you keep asking a Q without answering mine Sep 25 13:04:03 not very friendly Sep 25 13:04:08 and i dont learn Sep 25 13:04:11 WTF? Sep 25 13:04:27 i try to hepl you idiot Sep 25 13:04:56 i am not friedly becaus i ask you if you tried why i think will work fine? Sep 25 13:05:03 yes but like to know why its does not work from rc.local... and first thing you say screw rc.local Sep 25 13:05:13 do not learn anything from that Sep 25 13:05:29 so i just need to presend you with a solutionand you have to do nothing? Sep 25 13:05:56 no just tell me why it does not work when commands are run from rc.local.... Sep 25 13:06:00 for starters Sep 25 13:06:53 reset you rc.local to original start, get to know a simple upstart script and then let it autostart, that will worl with 99% chance in my opions, so not i am dont beeing "not very friedly" Sep 25 13:07:04 what is wrong with people? Sep 25 13:08:13 Bo_DK: i'd try do diagnose it one after the other. have some output logged to a file, maybe you're trying to write to a path that does not yet exist or such at that time. Sep 25 13:08:25 Am i wrong here? ie want to know why it fails ? Sep 25 13:08:45 Bo_DK: basically, get more information instead of just "does not work" Sep 25 13:08:47 should that not be the first thing... ie know why before just doing something else Sep 25 13:11:29 like i said - find it out. i do not know why. Sep 25 13:11:50 use echo to a file and redirection to log your debugging messages. Sep 25 13:15:22 guess i'm the arsehat here.... Sep 25 13:15:33 huh? Sep 25 13:16:11 what about the hints on how to debug your findings are not to your liking? Sep 25 13:17:01 or do you have me on ignore? well in that case - whatever. Sep 25 13:20:56 Bo_DK: get the Unix System Administration Handbook (http://www.admin.com/) Sep 25 13:21:04 Bo_DK: read it, learn it, come back when you still have questions Sep 25 13:38:27 Iam trying to write an eeprom... and read some examples like Null cape and Kellers blog.. but I am confused about details on new 3.8 kernel could make this exemples outdated Sep 25 13:59:56 Hi there, would it be possible to port Ubuntu touch to the beaglebone black? Sep 25 14:03:07 Fo2adZz: not that it would make much sense, but probably Sep 25 14:04:04 dm8tbr: thanks Sep 25 14:11:32 the BBB CPU does not care what code it runs Sep 25 14:13:12 av500: it doesn't like my SPARC code very much :( Sep 25 14:13:33 nobody likes sparc code... Sep 25 14:16:22 I'm looking at the option of powering my bbb off a transformer with a lithium battery in the middle as blackout protection lithium battery -- I'm thinking something along the lines of [BBB <- LiBat <- ?V DC <- 240V AC] -- anyone see/done something similar? Sep 25 14:17:16 use a "battery tank" Sep 25 14:17:27 one of these mobile phone chargers Sep 25 14:17:35 DC->5V->tank->BBB Sep 25 14:17:44 they come in all sizes Sep 25 14:18:02 actually, I apologise -- google eventually found this for me: http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/08/10/bbb--rechargeable-on-board-battery-system Sep 25 14:18:17 another round of applause for the beagle mob -- that's bloody fantastic Sep 25 14:19:02 Yes I use on of this chine 12000 miliamps endure 6 hours using hdmi Sep 25 14:19:25 pkh: yes, you can do that too Sep 25 14:19:34 my BBB does not havbe these pins yet Sep 25 14:19:38 but I think production units have Sep 25 14:19:55 oh wait, I have later BBBs too Sep 25 14:19:57 but where.... Sep 25 14:19:57 ah, I assumed they were all missing and it was up to the user to solder them in Sep 25 14:20:10 well, the pads should be there Sep 25 14:20:24 the TP5-TP8 are on my BBB just behind the 5V plug Sep 25 14:20:34 ok Sep 25 14:20:40 then you can do as described there Sep 25 14:20:42 I guess Sep 25 14:21:34 so, I'l suck it and see when I get a chance, but I assume that when the 5V goes out, all USB powers down and the core ticks along until the 5V is reattached. Sep 25 14:21:35 anyone have a good tutorial about program the eeprom for a new cape on kernel 3.8 ? alredy seen Derek Malloy vids and Null cape example but nothing happens... Sep 25 14:22:04 http://papermint-designs.com/community/node/331 Sep 25 14:22:19 very good tutorial... Sep 25 15:23:46 I'm having the USB problems mentioned in various locations seems to be to downgrade to the 3.2 kernel instead -- anyone knwo where I can find out which version (short of downloading every one) made the jump? Sep 25 15:24:14 there's a word missing in there somewhere -- 'the solution' Sep 25 15:28:29 how to install qemu in windows Sep 25 15:28:54 ?? Sep 25 15:29:14 rathijeet: wrong channel Sep 25 15:29:25 I want to emulate qnx on it Sep 25 15:29:36 rathijeet: wrong channel Sep 25 15:35:23 hi! is it possible that BBB-eMMC-flasher-2013.09.12.img.xz is not a flasher image? it boots up with the angstrom prompt from my sd card... Sep 25 15:37:06 flashers are angstrom too Sep 25 15:37:16 boot prompt and all Sep 25 15:37:30 i thought they did not display the prompt before Sep 25 15:39:14 i can also log in so it does not seem to flash anything Sep 25 15:41:17 Anyone trye dprogram I2C eeprom through /sys/bus/i2c ? Sep 25 15:41:19 av500: ideally an initramfs with no shell and a custom init for the purpose Sep 25 15:42:31 Anguel: I could login into the flasher over serial Sep 25 15:42:36 and see emmc.sh run Sep 25 15:43:20 av500: i can login through ethernet, how can i check if emmc.sh is running? Sep 25 15:43:57 ps aux Sep 25 15:44:09 av500: a yes, i see it :) Sep 25 15:45:30 av500: {emmc.sh} /bin/bash /usr/bin/emmc.sh Sep 25 15:45:43 thats the flasher Sep 25 15:45:46 so i will wait :) Sep 25 15:46:04 sorry for the confusion Sep 25 15:48:02 what is actually BBB-eMMC-flasher-v2013.06-2013.09.12.img.xz ? is this based on a new Angstrom? Sep 25 15:49:07 its a flasher Sep 25 15:49:15 that flashes -v2013.06-2013.09.12 Sep 25 15:51:22 av500: I had in mind a kernel + cpio composed of static compiled init and a flasher.bin. The image/firmware would reside on some block device (maybe another card) together with a file with the flasher-options to append. The init would scan the devices, find the image and launch the flasher with its options Sep 25 15:51:55 av500: see, it is basically kexecboot but instead of kexec we execve the flasher Sep 25 15:52:03 sure Sep 25 15:52:14 zero user intervention Sep 25 15:52:17
