**** BEGIN LOGGING AT Sun Jun 16 02:59:58 2013 Jun 16 03:59:53 yee-hah! Jun 16 04:01:16 drunk? Jun 16 04:02:09 non-booting uSD still has to participate in the boot process. three lines in a uEnv.txt file (in a FAT, of course) cures all: https://groups.google.com/d/msg/beagleboard/lEMH0rvm6Ys/HOyNKFznNn8J Jun 16 04:02:53 there's a good discussion with lots of juicy details that ought to be in the manual about how the boot actually works in that thread Jun 16 04:05:10 PS: Android phone is overkill. An old Sony PRS-600 was more than sufficient. Guess I borrowed a more recent laptop last time I needed to access an SD card, have to address that shortcoming... Jun 16 04:09:24 XFaCE: Mouser was shipping A5B about a week ago Jun 16 04:10:32 mranostay: finding this was better than a stiff drink. now I can go to sleep :-) Jun 16 04:20:27 martinm: ah, so it'll be awhile till C is shipping. How long is it usually before the latest revision is shipping? Jun 16 04:22:04 no idea. this was the first Beagle* I've acquired :-) Jun 16 06:10:56 hello Jun 16 06:10:57 i just bought a beaglebone black Jun 16 06:11:21 when i connect an arduino via usb, it doesnt power on(arduino) Jun 16 06:11:58 How do you power the Beaglebone black? Jun 16 06:45:10 any cool projects on the beaglebone black so far? Jun 16 06:45:44 i'm only planning for mini local servers for local mesh. **** BEGIN LOGGING AT Sun Jun 16 07:13:03 2013 Jun 16 12:06:40 Hi Jun 16 13:37:47 hi @all Jun 16 13:38:55 I try to install locate, (find-utils), but opkg did not find. Where is a similar to sources.list? Jun 16 13:39:51 or what is my problem? Jun 16 14:50:05 <_av500_> wunix: opkg update Jun 16 14:50:08 <_av500_> opkg list Jun 16 15:48:38 Hi. Jun 16 15:49:07 Has anyone had ti StarterWare working on the Beaglebone Black ? Jun 16 15:58:09 <_av500_> should be the same as for beaglebone white Jun 16 17:47:11 which version of the tiwlan source is known to work with the tiwi-ble cape and this tree? https://github.com/beagleboard/kernel/tree/beaglebone-3.2 Jun 16 17:47:54 seems like the pinmuxes are set up right. now i just have to find the right version of the driver source to go with it. i'd default to "latest", but i've been burned by that in the past. Jun 16 18:15:15 Any book recommendations for the hobbyist on Analog circuits? For someone without a background on electronics? Horowitz was suggested, but I also heard that it might not be the best book for the hobbyist Jun 16 18:19:36 it worked for me Jun 16 18:21:57 mru: Think I should go for it? I'm good at programming but the math in analog circuits scares me Jun 16 18:22:01 I recommend it too Jun 16 18:22:13 AoE avoids math as much as reasonably possible Jun 16 18:23:33 1/RC Jun 16 18:24:55 SpeedEvil: Hmm, okay - maybe I'll take the plunge and buy it. I feel my skills are limited by my inability to understand analog circuits Jun 16 18:25:19 Also - ##electronics Jun 16 18:26:22 I once fell asleep on a beach reading that book and ended up with sun poisoning :( Jun 16 18:27:12 plastygrove: So - put suntan lotion on first Jun 16 18:27:18 SpeedEvil: Thanks for the link - the ebook looks good Jun 16 18:27:45 I haven't read that ebook - I probably should skim it to see if it's sane Jun 16 18:30:53 SpeedEvil: Got my suntan! Just need the book now :) Jun 16 18:30:56 :D Jun 16 19:30:19 Has anyone else had problems with avahi-daemon.service running wild? Just cought it causing systemd to consume all the CPU. Helped by masking it out, but I have no idea what the sideeffects are : S Jun 16 19:31:34 Anyways, I can now SSH to my other BBB, had a lot of trouble going back and forth between two BBBs. Jun 16 19:32:55 exploring BBB information to see if it would be a good platform for me.. is there a good summary out there that describes the expansion interfaces on the pins in more detail? I know there are a number of UARTs, I2Cs, SPIs etc but not all of them can be used at the same time and the BBB HDMI/eMMC at least seem to gobble up some pins.. same for power management? Jun 16 19:33:51 the System Reference Material does list a lot of information but let's just say that a LOT of the things listed on the pin tables I have no idea what they are :) Jun 16 19:34:50 like "eQEP2 strobe" or "ehrpwm1_tripzone_input" Jun 16 19:35:22 Vaizki, what do you need? You can at least get i2c, spi and UART working without interfering with eMMC and HDMI Jun 16 19:35:24 well, you can look them up Jun 16 19:36:13 elias, can I get a second UART or just TTL serial port with the i2c and spi? Jun 16 19:40:09 It's all 3.3V signals, but you should get two uarts in adddition to spi and i2c Jun 16 19:41:29 Assuming you do not need rts/cts etc. Jun 16 19:44:50 yea I need one full serial port with rts-cts-dtr etc if possible and I will put a serial driver on it, the other can be just tx/rx Jun 16 19:47:47 the UART0 which is on a separate header, that is not shared with the usb client if, right? Jun 16 20:06:50 ok if I read this correctly, I can have UART0 on the debug header for serial console.. uart 1 on P9 24&36, uart2 on P9 21&22 but RTS/CTS is a bit tricky because they are in the HDMI framer pins for uarts 2-5 and in the cape eeprom i2c2 for uart 1 Jun 16 20:15:11 24 & 26 for uart1, 21 & 22 for uart2 shoudl be ok. 19 & 20 for i2c2 and 28, 29, 30, 31 for SPI. Jun 16 20:16:06 elias, thanks for confirming.. and the uart0 is completely independent of the USB serials etc? Jun 16 20:16:19 it just has getty running on it I guess? Jun 16 20:16:35 g_serial I think. Jun 16 20:17:15 Ah, sorry, yes independent of USB. There is also a g_serial available as a module- Jun 16 20:17:44 ok.. but cts/rts for one port doesn't seem that easy without losing support for cape eeprom? Jun 16 20:18:06 sorry don't know g_serial.. is that the usb gadget serial? Jun 16 20:20:23 Yes, usb gadget serial, and you are right about the rts/cts, they are all in conflict with either I2C2 or LCD_data. Jun 16 20:21:34 so g_serial module creates a virtual serial port over USB that is completely separate from the uart0 debug header? Jun 16 20:21:45 and I can run serial logins on both of them? Jun 16 20:21:46 yes Jun 16 20:22:27 sounds good.. I guess I could just hack cts/rts with random GPIO pins Jun 16 20:24:11 it's not that I really even need the HDMI at all. but the BBB is a nice price compared to the rest of the BB family. Jun 16 20:24:12 Bing Jun 16 20:25:05 I have a bunch of RasPis but their expansion is limited to say the least so looking for alternatives Jun 16 20:25:24 Yes it is. And the pi is a dog Jun 16 20:25:45 unlike a beagle which isn't a dog? ;) Jun 16 20:26:06 The beagle is a fruit Jun 16 20:26:15 ah. my bad. Jun 16 20:26:24 Woof woof Jun 16 20:26:35 english isn't my native language, got them mixed up and all. Jun 16 20:27:16 The bbb is pretty good. First few weeks were a bit rough but now the really annoying issues have been resolved its all good Jun 16 20:27:30 tbh I have found the Pi to be very nice for the price. My biggest argh is with the USB and indirectly the Ethernet just dropping stuff Jun 16 20:28:14 maybe it's fixed now but I haven't been keeping up Jun 16 20:28:29 Yes the Ethernet on the pi is crap so is the power supply. Jun 16 20:30:20 how is Arch on the BBB? I'm using Arch on PI so would prefer to use it on BBB also Jun 16 20:31:02 I've really enjoyed the bbb Jun 16 20:31:10 I've had a rpi for awhile and not done anything with it Jun 16 20:31:16 it's less inspiring than the bbb Jun 16 20:32:16 talking about power, is it possible to sleep the BBB into a very low power draw state and then use an external interrupt to wake it up very very quick? Jun 16 20:35:24 the PMIC does seem pretty capable Jun 16 20:40:18 Vaizki: what about DRAM refresh? Jun 16 20:40:52 yea sure fast wakeup would mean ram is refreshed. Jun 16 20:42:48 the TPS65217C there seems to be capable of keeping the DDR refreshed while the cpu is napping Jun 16 20:44:30 this is for a solar-powered project and I live in Finland where during the winter time there is not that much sun. So I would prefer to have a MCU like the MSP430 in charge and kicking the BBB up when needed Jun 16 20:47:32 well maybe I'm going to order two BBBs and get my oscilloscope warmed up for some testing Jun 16 21:01:48 Vaizki: I did some numbers to see what sized panel I'd need to keep a raspberry Pi awake 24*7 Jun 16 21:02:07 Vaizki: I'm in scotland - it worked out somewhere about 250W solar panel and 100Ah*12V battery. Jun 16 21:02:15 And it'd still go down 2-3 days a year probably. Jun 16 21:02:50 100Ah.. that's like a large car battery except you'd need a deep discharge one Jun 16 21:02:54 yes. Jun 16 21:03:20 yeah that's like 8-10 UPS batteries :/ Jun 16 21:03:20 That's assuming the panel does not get snow-covered Jun 16 21:03:31 ssi: about 13 of the teeny ones Jun 16 21:03:42 yea the little 7ah ones Jun 16 21:05:14 MSP430 can stay active with less than 1mA of 1.8V power... Jun 16 21:05:45 The n900 phone needs about 3mA@4V in suspend IIRC Jun 16 21:05:58 1mA of that is probably RAM Jun 16 21:06:05 (omap3630) Jun 16 21:06:41 yea in suspend the MSPs go really really low, like 0.1uA if you don't care about RTC Jun 16 21:07:27 Microcontrollers - pick the right one, and you're into not many nanoamps Jun 16 21:07:30 but anyway, my idea was to use something like an MSP to wake up a BBB or Pi as needed Jun 16 21:07:52 But you can't cope with a (say) 30s boot? Jun 16 21:08:07 Actually - you should be able to shave boot to under 5 Jun 16 21:08:09 which is why I asked about BBB sleep modes, the docs say something about them but mostly that SW support is lacking Jun 16 21:08:31 What's your maximum response time? Jun 16 21:10:01 I would like to be in the millisecond range, otherwise I might as well just boot it Jun 16 21:10:21 electronics without math is like... words fail me. Jun 16 21:10:21 ah Jun 16 21:10:41 ? Jun 16 21:12:12 hmmmm BBB supports real time scaling to lower the MHz as needed.. that's a bonus Jun 16 21:12:27 Basically irrelevant though Jun 16 21:12:35 If you want actual suspend-like power use. Jun 16 21:12:39 really? not much savings there? Jun 16 21:12:52 It may shave 50, maybe 75% tops. Jun 16 21:13:12 But you want it in some form of actual suspend state, if you're looking for milliwatt not watt power use. Jun 16 21:14:03 ok, it seems like this is what I would need.. http://processors.wiki.ti.com/index.php/AM335x_Power_Management_User_guide#Suspend_.26_Resume Jun 16 21:14:29 but someone commented it's not supported on the Ångström dist Jun 16 21:15:12 I mean on the one that ships with the BBB Jun 16 21:15:39 The other issue is that is the hardware required to support suspend states all there. Jun 16 21:16:00 well looks like the PMIC and CPU can do it all together Jun 16 21:16:08 what happens if you echo 'mem ' to /sys/power/state Jun 16 21:16:17 I don't know, I don't have a BBB yet Jun 16 21:32:29 very little info on what the power consumption could be cut down to without sleep Jun 16 21:32:51 the SRM figures are with HDMI monitor, USB hub, Ethernet etc all in use Jun 16 21:40:41 deep sleep apparently is 7mW or standby @ 25mW Jun 16 21:42:45 deep sleep for me too& Jun 16 22:23:17 Hi all. When writing this image has anyone ever had a situation where no kernel module are loaded? - ubuntu-precise-12.04.2-armhf-3.8.13-bone20.img Jun 16 22:27:56 ?.and taking the exact same image to another device, and lsmod, and it's populating Jun 16 22:27:58 WTF Jun 16 22:42:28 hello Jun 16 22:42:33 how are you? Jun 16 22:42:45 i want to buy a beaglebone black Jun 16 22:43:01 for connect webcam Jun 16 22:43:09 and take pictures Jun 16 22:43:16 it is works? Jun 16 22:43:30 can i conect a webcam in bealglebone black? Jun 16 22:43:34 yes Jun 16 22:43:51 and take Hd pictures? Jun 16 22:44:08 if your cam is hd, i dont see why not Jun 16 22:44:17 ok Jun 16 22:56:16 Is there anything to update on the BBBs? Firmware or something? Jun 16 22:56:37 i.e. I have 5, and two behave strangely - not loading any kernel modules Jun 16 23:34:00 How can I tell what version/revision my BBB is Jun 16 23:34:01 ? Jun 16 23:35:31 is there a sticker on the side of the 46 pin connector? my A5B has a serial number and "A5B" printed on such a label Jun 16 23:39:41 Ours says on the box Jun 16 23:39:47 for the software, the ID.txt file in the eMMC's FAT partition identifies the system image Jun 16 23:40:09 ah, yeah, there it is, stamped on the end, too :-/ Jun 16 23:40:19 * narcos looks Jun 16 23:41:15 Ah yeah - A5B Jun 16 23:41:27 Hmmmmmmm Jun 16 23:41:45 Where did it say that ? Jun 16 23:43:04 Some on the 46 pin connector, some on the ethernet jack Jun 16 23:43:09 A5A or A5B in my case Jun 16 23:43:12 Oh ok Jun 16 23:43:28 Anyone got Ubuntu running on their BBB ? Jun 16 23:44:49 I'm using ubuntu-precise-12.04.2-armhf-3.8.13-bone20.img from http://s3.armhf.com Jun 16 23:44:54 But getting a weird scenario Jun 16 23:45:05 On some of my boards, kernel modules are loaded, on some, not Jun 16 23:45:19 But the revision doesn't seem to be the differentiator Jun 16 23:46:28 same SD card? Jun 16 23:47:05 yes Jun 16 23:47:17 very strange Jun 16 23:47:45 I agree :-/ Jun 16 23:47:58 dump dmesg to a file for each BBB and do a diff - see what the kernel thinks is different? Jun 16 23:48:16 ok I'll do that now Jun 17 00:00:04 Doh.... Jun 17 00:00:14 It seems my USB hub is at fault Jun 17 00:00:30 switching that, modules are loaded, hardware is detected Jun 17 00:00:31 FFS. Jun 17 00:01:00 After the 5th BBB behaving in this manner?. Jun 17 00:03:03 * narcos inserts some witty comment about occam's razor Jun 17 00:07:14 hey that thing is sharp! Jun 17 00:14:36 What powered hubs do you guys use? Jun 17 00:14:41 I'm using a belkin 4 port Jun 17 00:15:01 Seems good, as long as this one faulty unite isn't representative Jun 17 00:16:08 * mranostay dances back in Jun 17 00:16:26 narcos: they are all the same mostly Jun 17 00:19:56 ok Jun 17 00:20:33 I suspect the differentiator may be the PSU? And I'm not using theirs, I have a single 4A PSU with a Y splitter - one for the hub, one for the BBB Jun 17 00:25:14 BRB, rebooting Jun 17 00:25:53 When in doubt, reach for the giant-ass HP lab suppply. Will 5 volts at 50 amps be sufficient to allay such concerns? :p Jun 17 00:26:05 arc welder Jun 17 00:26:42 not regulated, but I like the idea. I've been pondering using the arc/tig supply for doing anodizing. Pretty sure at the 350A range I'd boil the solution, though. Jun 17 00:28:52 Hey guys, it looks like ArchLinux automatically adds a lost+found folder when I mount my sdcard after formatting. Is that going to botch things as the MLO needs to be the first file on the partition Jun 17 00:39:02 Any protips on using dd to create an image of the 2GB worht of partitions on a 8GB sd card? Jun 17 00:41:22 if it's an image file, then you just dd to the raw device (sdX) and that sets up the partitions. You can then extend the last partition and resize the filesystem, but that's what you get from all these Windows-based folks who don't understand filesystems :-/ Jun 17 00:45:22 Hmmm Jun 17 00:46:09 So, I downloaded a 2GB Ubuntu, and wrote it to an 8GB sd card. I booted, and have modified the setup. I now want to create an image of the 'new' setup, but when I just dd the SD card I get an 8GB image, which wastes a lot of time Jun 17 00:51:32 yes, images are a horrid way to duplicate filesystems that aren't near 100% full Jun 17 00:52:03 Make your partion just large enough to hold everything then dd. You can enlarge your partition after the image Jun 17 00:52:20 nah, that's the stupid way to do it Jun 17 00:52:59 then what Jun 17 00:53:06 tar will write an archive of the files and can put them back into place. no empty space copied! Jun 17 00:54:03 ah Jun 17 00:55:14 use the "do not cross mounts" option (sorry, I forget the exact name) so it won't grab all the dynamic junk in /proc and other pseudo filesystems Jun 17 00:57:52 Hmm Jun 17 00:57:56 I'm a little confused Jun 17 00:58:11 So my partition on my SD card is just large enough to hold everything Jun 17 00:58:23 Then I tar up the entire FS Jun 17 00:58:34 How do I migrate that to a new, blank sd card? Jun 17 00:59:10 ideally you could do this all offline - got a card reader? Jun 17 01:00:14 doing it in place on the black is rather tricky, since it only has one mountable sd slot. maybe mount an external drive or flash on the USB? Jun 17 01:00:53 Yes I have a SD card reader Jun 17 01:01:01 you still have to do some minimal prep on a blank sd or it will hang the boot :-( Jun 17 01:01:24 I'm going to be making lots of these, so I'd like as little trouble down the line Jun 17 01:01:56 It seems odd that I downloaded someone else's 2GB image, and all I want is to slightly modify it Jun 17 01:03:06 it's not the normal way to install Linux, no. These embedded/ARM guys do seem to do things... differently Jun 17 01:05:28 if you're using Windows, then just suck it up and make an 8G image, that's probably easiest. otherwise, well, I *think* there's stuff available to get Windows to work with ext2/3?/4??? filesystems, but you're beyond my help there Jun 17 01:08:12 I don't use windows Jun 17 01:08:19 I'm on a Mac, with Linux VMs Jun 17 01:11:27 * martinm thumbs up Jun 17 01:13:03 I do get the impression that a lot of the way these things are done is to cater to Windows - it was jarring the first time I ran into a nicely done howto install XXX, with all those screenshots of Windows dialogs... Jun 17 01:15:02 ah ok Jun 17 01:44:10 time tar czf home/root/sd/emmc-image.tar.gz --one-file-system . => 8m9.953s, 377976017 Jun 17 01:27 emmc-image.tar.gz Jun 17 01:45:06 not bad, df calls it 1.1 GB used, of course that includes wasted space in tail blocks in most files Jun 17 01:45:57 oh, this is from a boor from emmc, so / is the on-board flash partition **** ENDING LOGGING AT Mon Jun 17 02:59:58 2013
