Aug 13 08:01:39 -t Aug 13 08:51:24 * koen crosses another few items of the TODO as "hardware related, can't fix in software" Aug 13 08:53:41 koen: and no workaround in sw possible or allowed? Aug 13 08:55:59 av500: in related news: I've fixed the usb host problem. the controller sets the connection change status after a port reset and nvidia forgot to add the workaround clearing it in their newest usb rewrite Aug 13 08:56:03 janne: the best I can do is print a warning saying "Press the right button 3 times if you want to go left" Aug 13 08:56:54 the left button gpio is pulled high by another board Aug 13 08:57:01 don't let av500 daughter design the hardware Aug 13 08:59:18 janne: why not? Aug 13 08:59:20 ah Aug 13 08:59:23 well Aug 13 08:59:29 she's not even 2 Aug 13 12:12:25 koen: that sgx-driver you hoped wouldn't have the instant lockup-issue isn't out in the wild yet? Aug 13 12:20:50 tasslehoff: not that I know off Aug 13 12:34:50 I have an beagleboard xM and a bluesmirf, will it be easy to set up filetransfer with a cellphone with theese? How should I connect the bluesmirf to the board? Aug 13 12:47:58 Phasip: check the bbxms SRM and pick the relevant serial ports, for first :) Aug 13 12:48:30 (as for the "easy" part of the question, the answer varies for the respective definitions of "easy") Aug 13 12:51:36 bluesmirf isn't real bluetooth Aug 13 12:51:45 it's a dedicated SPP thing Aug 13 12:52:05 so it just forwards the data out of your serial port Aug 13 12:52:21 so filetransfer will have to be e.g. kermit or slip Aug 13 12:52:26 koen: SPP as is Specially Prepared Phenomenon? Aug 13 12:52:58 serial port profile Aug 13 12:53:10 aw. Aug 13 12:53:10 like those xbee dongles the arduino folks love Aug 13 12:53:23 xbee? like in zigbee? Aug 13 12:53:34 * LetoThe2nd tries not to barf onto his desktop Aug 13 12:53:41 xbee is to zigbee what TWI is to I2C Aug 13 12:53:55 same thing, no license costs associated with name Aug 13 12:54:16 LetoThe2nd: but I'm specifically talking about those wireless serial cables Aug 13 12:54:29 koen: using zigbee in the same sentence as i2c is quite derogatory. i mean i2c works. Aug 13 12:54:59 koen: hey, lets call that "WSC", make up a brand and sell it for $BIGCASH Aug 13 12:55:19 we need someone good looking to handle our social media Aug 13 12:55:47 hm. volunteers? Aug 13 12:56:35 I think we need someone with a hercule poirot moustache, horn rimmed glasses and a white v-neck t-shirt Aug 13 12:56:52 i don't think guerilla marketing works here. Aug 13 12:57:01 or go with the tried and tested formula: cute girl Aug 13 12:57:28 we should specifically not target nerds or technically knowledgeable people. prime target should be PHBs Aug 13 12:57:42 hence, cute girl. preferably a multitude of them. Aug 13 12:58:28 i mean, we're no interested in technically correct and valuable reviews and articles. we want $BIGCASH Aug 13 13:01:01 ...sounds like a "Bad Romance"(TM) after all. Aug 13 14:01:06 koen, did you see ht elink about Pfizer being corrupt? Aug 13 14:04:00 a company corrupt? Aug 13 14:04:03 unpossible Aug 13 14:04:03 koen, you don't need a person with a moustache as long as you run their photo through jkridner's app. Aug 13 14:16:44 Crofton: yes Aug 13 14:16:50 FCPA :) Aug 13 14:17:06 I figured you would be amused Aug 13 14:17:15 I was Aug 13 14:29:35 A friend of ours moved to Enschede Aug 13 14:29:55 He'll probably put a Dutch trombonist out of work Aug 13 14:30:27 lots of them are out of work already Aug 13 14:30:46 culture is a "left wing hobby" and lost most of its government funding Aug 13 14:32:33 if you ever get up thay way, you should stop in and check on him Aug 13 14:32:47 I'm sure his parents will want to know if he is behaving :) Aug 13 14:46:39 Crofton: they heard about these "Coffee shops" they have over there? Aug 13 14:46:54 koen, has audio been validated on the dvi cape? Aug 13 14:52:24 joelagnel: there's no audio on the dvi cape, only on the dvi+audio and audio cape Aug 13 14:52:44 joelagnel: but yes, audio out works on the dvi+audio and audio capes Aug 13 15:07:34 I have a BB xm rev C. I'm trying to get output to the monitor on the dvi. I've been searching around with google, but no luck so far. anyone able to assist or point me in a direction Aug 13 15:15:22 shawn: You need an HDMI to DVI adapter. Aug 13 15:15:38 YOu also need to be running a distro that produces output over DVI. Aug 13 15:15:51 Like the Angstrom demo that came with the board. Aug 13 15:16:19 i have the adapter. i'm using linux-3.4.6 which has the dss subsystem Aug 13 15:16:50 sorry, i should have put that up before Aug 13 15:16:50 What distro is running on top of the linux kernel 3.4.6? Aug 13 15:17:36 nothing. I used buildroot to roll everything together. Aug 13 15:18:00 Ah. Aug 13 15:18:19 Try the Angstrom demo that came with the board, and ensure the hardware and con nection is working. Aug 13 15:18:36 Past that, figure out what parts of thye system you left out in the buildroot step. Aug 13 15:18:55 ok. Aug 13 15:19:25 i'll give it a shot Aug 13 15:20:07 Good luck. Aug 13 15:43:21 hi Aug 13 15:43:49 lo Aug 13 15:44:45 after i installled ubuntu-11.10-r12-minimal-armel-2012-07-29 to my sdcard i get this error when booting Aug 13 15:44:49 http://paste.debian.net/183388/ Aug 13 15:44:56 is this an hw error - or is this a known bug? Aug 13 15:45:05 i have a beaglebone rev A6 Aug 13 15:45:15 und how can i fix it? Aug 13 15:45:25 i allso tried 12. something and it also doesnt work Aug 13 15:45:39 the beaglebard-xm is working as it should ... Aug 13 15:45:54 i downloaded the image from here Aug 13 15:45:56 http://elinux.org/BeagleBoardUbuntu#Precise_12.04_armhf Aug 13 15:46:06 or at least i used this documentation Aug 13 16:25:13 damn monday's Aug 13 16:25:19 * mranostay blames mru Aug 13 16:25:39 * mru blames ibm Aug 13 16:26:30 * mdp wonders if ibm is respondible for blue christmas as well Aug 13 16:26:37 responsible, even Aug 13 16:26:49 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54245 Aug 13 16:26:59 ^^ someone at ibm broke gcc Aug 13 16:28:38 bah, I was thinking "blue monday", but I'm happy to blame ibm [and canada] for gcc breakage too Aug 13 16:31:33 mranostay, any geiger hacking this weekend? Aug 13 16:32:20 assembled part of them on Sunday Aug 13 16:33:24 did you order extra tubes that you want to get rid of? Aug 13 16:35:38 well they are in europe right now :) Aug 13 16:36:56 ugh, I figured you had some sub-portion of the group buy..bah Aug 13 16:37:05 I should have found a use for this earlier ;) Aug 13 16:37:39 we were exploring a thought about a little radiation wardriving around the nuke plants here Aug 13 16:39:20 hi Aug 13 16:39:27 * mranostay hides Aug 13 16:39:58 Is anybody use ubuntu with LCD touchscreen? Aug 13 16:40:09 no that is an insane combo Aug 13 16:41:04 Is anybody use ubuntu with LCD7" touchscreen? Aug 13 16:53:51 mranostay: has there ever been a lack of insane people? Aug 13 16:54:19 mdp: there's no more radiation around a nuclear power plant than elsewhere Aug 13 16:54:35 they don't usually build them on top of uranium deposits Aug 13 17:05:35 mru: i pictured it like a coal plant. just shoveling ore into the core :) Aug 13 17:08:07 if you go inside, the radiation you're likely to be exposed to is actually less than outdoor background radiation Aug 13 17:08:33 unless there's a breach in the core containment Aug 13 17:12:04 mru: stop raining on mdp's parade Aug 13 17:12:12 mranostay, he's not Aug 13 17:13:20 the dosimeters used for maintenance workers doing electrical wiring and pipefitting work during shut-down regularly show higher than background radiation during the checks.. Aug 13 17:15:28 and yes, as long as there's also plenty of water in the spent fuel rod ponds...no issue ;) Aug 13 17:16:55 mdp: like how it takes 5-10 years to cool those down Aug 13 17:17:22 didn't that happend to fukushima? Aug 13 17:17:38 they just keep making more pools at our plant...been doing that since I was in grade school taking tours there Aug 13 17:20:35 * reanguiano looks, hopes nobody is making homemade dosimeters with beagle Aug 13 17:21:21 Why? Aug 13 17:23:26 reanguiano: sure Aug 13 17:23:38 * wmat waves hello at reanguiano Aug 13 17:24:17 mranostay, yes, the water supply in the pools went low during the disaster there. iirc, some countries encase the spent rods unlike .us Aug 13 17:25:08 * reanguiano waves to wmat Aug 13 17:25:33 reanguiano: i didn't know you lurked in here :) Aug 13 17:25:40 mranostay: :) Aug 13 17:26:51 in sweden the spent fuel is kept in a pool just outside the reactor enclosure for a few weeks until the worst radiation has died down Aug 13 17:26:59 I suppose there is no harm in homemade dosimeters if you are a hobbyist with access to hobbyist materials. Aug 13 17:27:02 then they move it to some underground caverns Aug 13 17:27:28 But if you are regulated by the NRC or a similar body I would think they would frown on such things. Aug 13 17:28:04 reanguiano: well duh :) Aug 13 17:28:31 * mranostay is sure this cape will have a legal CYA in the box :) Aug 13 17:29:00 mru, we still have no long-term storage facility here...it stays in the pools long-term Aug 13 17:29:35 mdp: well we have that one mountain :) Aug 13 17:29:40 those caverns aren't suitable for very long term storage either Aug 13 17:29:59 they've been debating for the last 30 years what to do when they fill up Aug 13 17:30:00 mranostay, still, no go Aug 13 17:30:21 mranostay: Yucca? No, they nixed that a few years ago. Aug 13 17:30:45 http://en.wikipedia.org/wiki/Yucca_Mountain_nuclear_waste_repository Aug 13 17:30:51 Cancelled in 2010. Aug 13 17:31:13 mranostay, there's issues in convincing everybody to let that waste travel through their states alone besides nobody wanting the facility in their backyard Aug 13 17:32:28 nobody lives in Nevada :) Aug 13 17:33:25 mmm...right Aug 13 17:33:52 tons of people live in the cities that the rails pass though from all corners though ;) Aug 13 17:35:31 mranostay, I think everybody's just waiting for Unicorn-powered turbines to solve the problem Aug 13 17:35:44 heh Aug 13 17:35:54 Molten-salt reactors would help. ;-P Aug 13 17:37:26 I hope salt doesn't become the ingredient for energy production ;) too many people would move here Aug 13 17:38:35 s/Unicorn/Nyan Cat/ Aug 13 17:38:42 mdp: I doubt your area specialises in thorium-flouride salt. Aug 13 17:42:21 agmlego, absolutely not ;) I'm feeling confident that NaCl will remain boringly essential to only existing use cases. Aug 13 17:45:16 mdp: well they do have sodium cooled reactors Aug 13 17:45:37 right, it's used in that process for lots of types of reactors... Aug 13 17:45:50 very dangerous since Na burns in the air and explodes with water :) Aug 13 17:45:59 like water it's a boringly essential tool Aug 13 17:49:37 several of those metals work well to liberate hydrogen...though mostly only Na is easily obtainable in a high school chem lab. Aug 13 17:51:48 mranostay, you should feel a few granules of Na on your skin... Aug 13 17:52:00 you're sweatier than you might think Aug 13 17:53:31 did this turn into #chemistry? :) Aug 13 17:53:58 * reanguiano was a fan of alt.cesium way back when Aug 13 18:14:39 So if I have an 2 SD cards, one configured correctly. I can use dd to make a copy using the command sudo dd if=/dev/sdX of=/dev/sdY correct? Aug 13 18:15:20 sure Aug 13 18:15:44 cool, As soon as my SD card reader starts working I'll try it Aug 13 18:15:55 as long as they're the same size Aug 13 18:16:02 target should be at least as large as source of course Aug 13 18:16:14 you can also transfer to your hard drive and back to the new card Aug 13 18:16:22 They're both 4GB so it should be okay Aug 13 18:16:50 not all 4GB are the same bit size bit for bit Aug 13 18:16:51 not all gigabytes are created equal Aug 13 18:17:33 even among the same brand there are sometimes differences :/ Aug 13 18:17:39 Well, that would upset me. Hopefully they are the same. Aug 13 18:18:12 it's easy enough to check Aug 13 18:18:30 as long as it's not the boot partition, tar should work Aug 13 18:19:01 hdparm is a good thing. Aug 13 18:19:05 how do I check and how do I tar? Aug 13 18:19:14 I use tar on rootfs frequently Aug 13 18:19:34 osu: hdparm might give you the info, or fdisk. Aug 13 18:19:47 Thank you agmlego Aug 13 18:19:51 or dmesg Aug 13 18:19:52 check the man page for tar if you still have question ask Aug 13 18:48:18 reanguiano: I was an alt.pave.the.earth believer more than anything Aug 13 18:50:04 av500: hey, could i use a bit of your ducati/dce knowledge ? :D Aug 13 19:07:25 mdp: cute Aug 13 20:01:33 hi Aug 13 20:04:13 I have ubuntu 12.04 into my beaglebone with a BeagleBone LCD7.... and I would like to use the touchscreen support... but, I don't know what driver I need to install it..... Aug 13 20:07:26 hi Aug 13 20:07:37 i have a beaglebone rev A6 Aug 13 20:08:12 after i installled ubuntu-11.10-r12-minimal-armel-2012-07-29 to my sdcard i get this error when booting Aug 13 20:08:13 http://paste.debian.net/183388/ Aug 13 20:09:00 i used the docu from here - http://elinux.org/BeagleBoardUbuntu#Precise_12.04_armhf - i also have a beagelboard-xm and it is working as expected - is this a heardware fault of the beagleboard or can i do something about it? Aug 13 20:09:15 http://elinux.org/BeagleBoardUbuntu Aug 13 20:47:32 _av500_: btw that snake cake freaks me out Aug 13 21:20:33 Hi, I found how to setup muxing to use uart2 and accessing it somehow using /dev/ttyO2 , but can somebody tell me how I should set the baudrate for uarts on a beaglebone? Aug 13 22:08:10 hi Aug 13 22:11:56 I have a beaglebone with LCD7" and ubuntu 12.04 distro. I compiled QT 4.8.2 embedded libs ....but my mouse, keyboard an touchscreen don't works Aug 13 22:12:20 how can I configure it for use it? I use "-qt-kbd-tty -qt-kbd-linuxinput -qt-kbd-qvfb -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -qt-mouse-tslib -qt-mouse-qvfb "options when I compiled embedded qt libs Aug 13 22:22:08 i run my program with this command: ./app -qws -mouse Aug 13 23:03:41 anyone here done any i2c with a beaglebone? Aug 13 23:09:33 possible Aug 13 23:34:10 i have an i2c LED controller connected to the bone's I2C2 on pins 19&20 of exp connector 9 (using 4.7k pull-ups on the SCL and SDA). if I do an "i2cdetect -l 3" it shows up at its expected address (0x41). When I do "i2cget 3 65 0" multiple times, I get "read error" and then occasionally an 0x11 which doesn't match the default state of the 0x00 register. Any thoughts on why i2cget might be failing and why when it does work, it returns a fun Aug 13 23:34:10 value? Aug 13 23:56:58 just fyi, feedback on a possible PandaBoard-NC can be posted on the pandaboard mailing list which also includes a mockup - https://groups.google.com/forum/?fromgroups#!topic/pandaboard/dLXGzHYdLjw%5B1-25%5D Aug 14 00:12:52 Lots of coding to be done. Aug 14 00:31:43 prpplague: that rj-45 connector expensive? Aug 14 00:32:27 mranostay: yea, and tall Aug 14 01:27:22 prpplague: what does the NC stand for? Aug 14 01:27:26 * mranostay puts on dunce hat Aug 14 01:28:11 *sigh* Aug 14 01:28:29 heh Aug 14 01:28:30 suppose if you don't click the link Aug 14 01:28:53 no connectors Aug 14 01:29:47 gah Aug 14 01:31:50 * mranostay puts on dunce hat again Aug 14 01:32:47 prpplague: so how much does the BOM cost drop? Aug 14 01:33:18 mranostay: just evaluating atm, can't give an exact figure Aug 14 01:35:19 BOM? Aug 14 01:36:00 KeatonT: bill of materials Aug 14 01:36:11 ah **** ENDING LOGGING AT Tue Aug 14 02:59:58 2012
