**** BEGIN LOGGING AT Wed Jun 18 02:59:59 2014 Jun 18 03:04:55 Anybody can speak spanish? Jun 18 03:06:05 I have a project of investigation on beaglebone black Jun 18 03:06:20 Anybody can help me? Jun 18 03:24:29 you'll have to be more specific if you need help Jun 18 03:24:40 ... and stick around :/ Jun 18 06:58:17 Hi Jun 18 06:59:51 I have question about how to use the sleep mode on the latest debian software version. Jun 18 07:00:48 question away... Jun 18 07:02:21 Well, I found of that u can put the Beaglebone in sleep by doing something like this: echo mem > /sys/power/state. Or use the rtcwake command Jun 18 07:02:55 If I looke in /lib/firmeware I can see that the am335x-pm-firmware.bin is present so these commands should work right ? Jun 18 07:03:48 rtcwake gives me: "rtc0 not enabled for wakeup events" and the echo to /sys/power/state gives me " write error: No such device" Jun 18 07:05:06 I've been googling about this for days but I don't understand why it is not working. I read some people compiled the kernel with the am335x-pm-firmware.bin but in this latest debian version it is already included I think ? Jun 18 07:06:07 If anyone could help me with this issue that would be great :) Jun 18 07:09:46 it may be an incomplete feature... haven't tried with the 3.8 kernel Jun 18 07:10:40 trying with the 3.15-rc8 kernel at the moment, but it may not be working. Jun 18 07:11:43 ok thanks for that. Jun 18 07:13:11 sudo rtcwake -m standby -s 10 Jun 18 07:13:12 rtcwake: suspend to "standby" unavailable Jun 18 07:13:28 sudo rtcwake -m mem -s 10 Jun 18 07:13:28 rtcwake: wakeup from "mem" using /dev/rtc0 at Fri May 16 07:58:00 2014 Jun 18 07:13:36 but never seems to recover... Jun 18 07:15:34 Hm, if I execute the same commands as you I always get: rtc0 not enabled for wakeup events Jun 18 07:20:45 #vagrantc, you were able to put it in sleep mode bit it did not wake up ? Jun 18 07:21:27 seems to be the case Jun 18 07:22:31 though i'm using the kernel from debian experimental Jun 18 07:22:45 3.15-rc8 Jun 18 07:23:30 the image ships with a significantly patched 3.8 kernel, though there's also a patched 3.14 kernel available... Jun 18 07:23:52 the newer kernels lack capemgr support Jun 18 07:23:58 aha ok Jun 18 07:27:45 Have you any suggestion what I can do to make it working ? Jun 18 07:29:17 rtc wake also gives me this error: rtcwake: open failed: /sys/class/rtc/rtc0/device/power/wakeup: No such file or directory Jun 18 07:33:02 or did anyone get the pm-suspend working ? It is just doing nothing here. Jun 18 07:33:56 * vagrantc remembers people being excited just to gt the power button working not so long ago Jun 18 07:35:10 :) Jun 18 07:41:51 So, for now there is no way to get the beaglebone out of sleep mode using rtcwake ? Jun 18 07:49:56 i think the rtc doesn't actually work Jun 18 07:50:03 at least in my current install Jun 18 07:51:32 ok good to know, then I have to use an external timer. Quite stupid since I now the PLIC has everything I need Jun 18 07:52:56 *PMIC Jun 18 07:53:13 it's still a little rough around the edges in some places... Jun 18 07:58:31 I think I'm going to try your Kernel version vagrantc, since you were at least able to put in in sleep Jun 18 08:08:02 speaking of sleep... Jun 18 08:14:51 yes ? Jun 18 08:15:06 Thank you vagrantc, I used another kernel and now at least the rtcwake command is working Jun 18 08:15:13 but just like you, It does not wake up :( Jun 18 08:46:08 Hello all, I would like to know about BBB interfacing with different glcd running on starterware by Texas Instruments Jun 18 08:47:37 glcd? Jun 18 08:49:34 and starterware is a TI thing, ask TI e2e or such Jun 18 08:50:30 Guest91778: we dont really know starterware Jun 18 08:50:45 http://e2e.ti.com/support/embedded/starterware/f/790.aspx Jun 18 08:57:20 I want to know is this board BBB can be configurable with any type of graphics lcd's via SPI communication or only interface with VGA display Units.? Jun 18 08:57:50 it has not VGA Jun 18 08:57:56 it doesn't do VGA, at all Jun 18 08:57:59 it has SPI Jun 18 08:58:00 I2C Jun 18 08:58:04 HDMI Jun 18 08:58:06 an LCD controller Jun 18 08:58:08 and even HDMI Jun 18 08:58:14 and GPIOs Jun 18 08:58:23 so, you can connect many types of displays Jun 18 08:58:30 even VGA with some glue Jun 18 08:58:40 bitbang an ISA VGA card? ;) Jun 18 08:59:07 okk got the point Jun 18 08:59:38 currently I am working with Code composer studio from TI Jun 18 08:59:59 starterware is one of the solution of TI Jun 18 09:00:17 i would like to program BBB on same platform Jun 18 09:00:25 is it possible...?? Jun 18 09:00:26 let's ask the other way around. what are you trying to do with the BBB Jun 18 09:01:33 some internal mathematical calculations for graphics generation on spi or i2c based small lcd's. Jun 18 09:02:09 the BBB is a small Linux computer Jun 18 09:02:10 e.g 240x320 tft spi Jun 18 09:02:24 you can write code in any editor Jun 18 09:02:27 the BBB is not an MCU Jun 18 09:02:29 compile it Jun 18 09:02:31 run it Jun 18 09:02:35 much like on your PC Jun 18 09:03:23 as i have seen that BBB has a processor in built on it Jun 18 09:03:40 yes, the BBB has a CPU Jun 18 09:04:35 okk one more question I have Jun 18 09:05:47 fine thanks for your valuable feedback Jun 18 09:05:49 :) Jun 18 09:05:57 just ask Jun 18 09:06:59 Actually i want to know which ubuntu version be good for it ? Jun 18 09:07:09 debian Jun 18 09:07:24 okk Jun 18 09:24:49 *g* Jun 18 09:27:37 I like dogs.... Jun 18 09:28:02 don't we all? Jun 18 09:28:24 * KotH likes sophie Jun 18 09:28:35 koth your dog? Jun 18 09:28:53 Lobs: show woglinde a pic of sophie :) Jun 18 09:29:13 i want to know how to load Windows embedded 7 os into Beagle board? Jun 18 09:29:33 Ronny_: ask TI Jun 18 09:29:41 Ronny_: ask Microsoft Jun 18 09:29:51 ok..thank you Jun 18 09:30:03 Ronny_ sorry you are third here I am seeing askgin about windows Jun 18 09:30:09 woglinde: third? Jun 18 09:30:17 and that over 5 years or so Jun 18 09:30:17 TI has a wince bsp IIRC Jun 18 09:30:19 woglinde: there is at least one every month Jun 18 09:30:20 koth yes Jun 18 09:30:27 hm okay I am not always on Jun 18 09:30:34 http://lobs.sytes.net/sophie/sophie.jpg Jun 18 09:30:55 woglinde: it's mostly indian people Jun 18 09:30:56 * tbr goes d'awwwwww Jun 18 09:31:24 I do not klick pictures from irc Jun 18 09:31:49 woglinde: i vouch for Lobs and that pic Jun 18 09:32:24 woglinde: even if he is a kiwi and doesnt like chocolate, he is trustworthy Jun 18 09:33:27 woglinde: but dont ask him aboug fat nurses! Jun 18 09:33:31 about* Jun 18 09:36:44 Just bought a BeagleBone black. I follow to the getting started guide, however I could not browse using http://192.168.7.2/, Anyone got any idea? Jun 18 09:37:46 Henry_: 1) "does not work" is not an error description Jun 18 09:38:03 Henry_: 2) what has your research so far shown? Jun 18 09:38:11 Henry_: 3) what did you try to resolve the problem? Jun 18 09:38:28 Henry_: 4) do you like chocolate? Jun 18 09:39:02 * Lobs ponders where the ip address was plucked from Jun 18 09:39:16 5) connect to serial console Jun 18 09:39:28 lobs oe qemu stuff Jun 18 09:39:31 they have the same Jun 18 09:39:43 Koth, hello Jun 18 09:39:46 woglinde: hello Jun 18 09:39:54 hello beaglers. Jun 18 09:39:55 he mrpackethead how is it going Jun 18 09:40:01 Crazy busy. Jun 18 09:40:02 australia plays tofay Jun 18 09:40:07 and will lose Jun 18 09:40:10 Plays what?

Jun 18 09:46:06 :-0 Jun 18 09:47:40 Is there anybody capable of waking up the Beaglebone after entering sleep mode ? Jun 18 09:47:51 its all on the wbesite Jun 18 09:48:59 If I doe this "rtcwake -s 50 -m mem " it does not wake up after 50 seconds, at first the caender of the RTC was wrong put but now it is right Jun 18 09:49:50 jonasvanpelt so maybee you found a bug in the kernel Jun 18 09:49:53 gratz Jun 18 09:51:29 Maybe, but I would like to make it work :) Jun 18 09:53:19 get familiar with kernel debugging Jun 18 09:53:34 and debugging with pm states Jun 18 09:53:39 I guess thats no fun Jun 18 09:55:56 :) Jun 18 09:58:35 has anybody another way to wake it up ? Jun 18 09:58:42 the power button is not working Jun 18 09:59:08 * Lobs passes jonasvanpelt a rock Jun 18 11:05:43 I discovered that the RTC is working and generating interrupts. Only problem is, when I go to suspend mode, the Beaglebone never wakes up again Jun 18 11:06:00 Anybody knows how this comes ? Jun 18 11:06:13 Ones the Beaglebone is in sleep mode, I cannot wake him, even not with the power button Jun 18 11:07:26 Once* Jun 18 11:13:02 probably because you shutdown the clock source of the rtc Jun 18 12:01:33 I have a problem with can bus, I enable can bus of can1 in both kernel 3.8 and 3.2 Jun 18 12:02:01 connecting to oscillograph, but I can't detect any wave Jun 18 12:02:20 the gnd of oscillograph is connected to gnd of beaglebone Jun 18 12:02:28 I use beaglebone black Jun 18 12:03:47 have you configured the pins correctly? Jun 18 12:06:53 KotH, I am not sure Jun 18 12:07:27 KotH, in kernel 3.8 I just each 'BB-DCAN1' to /sys/class/device/bone.o*/slots Jun 18 12:07:44 should I disable some pins? Jun 18 12:08:00 ayaka: if you are not sure, then most probably not Jun 18 12:08:23 KotH, could you give me guide about how to enable it? Jun 18 12:09:04 you can find one (or a dozen) using google Jun 18 12:09:16 KotH, yes I have follow one guide Jun 18 12:09:58 http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/ Jun 18 12:10:07 but it doesn't tell me what shall I disable Jun 18 12:10:46 it just told me that compile a dts(I did) and echo BB-DCAN1 > /sys/devices/bone_capemgr.*/slots Jun 18 12:10:48 step #1: understand what you are doing instead of just blindly following #exactsteps Jun 18 12:11:09 learn what DT is, how it works and how to use Jun 18 12:11:59 I have worked with DT in samsung platform Jun 18 12:12:12 but the ocp in Ti really confuse me Jun 18 12:13:33 what the av500 is ocp? Jun 18 12:14:31 Omni Consumer Products Jun 18 12:15:15 sorry, what is the meaning of "av500" Jun 18 12:15:49 is there some guide of can in BBB? I have no idea what is wrong Jun 18 12:16:15 https://www.google.com/search?q=beaglebone+can Jun 18 12:16:36 that is what I have done Jun 18 12:16:45 the search result are all the same Jun 18 12:17:14 that tells you that not many people are using CAN on the BBB Jun 18 12:17:47 should probably search canbus and not can Jun 18 12:17:49 yes, I know that, but my homework is making it work Jun 18 12:18:02 *g* Jun 18 12:18:12 there task they cannot be accomplished Jun 18 12:18:19 +are Jun 18 12:18:36 yes, I did, I was thinking about buy a caps but it can be in my country Jun 18 12:18:44 s/task they/tasks that/ Jun 18 12:20:56 dark-fx yes shame on me Jun 18 12:21:03 * KotH wonders what kind of school gives a "make canbus work on bbb" type of homework Jun 18 12:21:15 a university Jun 18 12:21:22 woglinde: also "chocolate on you" Jun 18 12:21:31 hey, if you're correcting things. Jun 18 12:22:12 back in my day it was make an amplifier type work, how things progress :-) Jun 18 12:22:52 and I learned that lab assistants never look at the back of a bit of vero board Jun 18 12:23:08 Mr. Foo CANhD. Jun 18 12:25:11 is there a limit on the uSD that can be handled by a beaglebone? Jun 18 12:28:06 * KotH never had to solder anything in his uni days Jun 18 12:28:16 I maybe to modify the dts to enable can bus at default and disable uart1 Jun 18 12:28:35 ams: 2TB Jun 18 12:29:13 KotH: coolies, thanks. Jun 18 13:34:20 when I configure can bus I got something like this http://fpaste.org/110744/40309730/ Jun 18 13:34:33 there must be something wrong in my dts but I can't find it Jun 18 13:36:17 I modify the dts later, the log http://fpaste.org/110753/30985471/ the dts http://paste.fedoraproject.org/110752/98530140 Jun 18 14:03:02 ayaka, try pinctrl-0 = <&dcan1_pins>; Jun 18 14:04:16 NishanthMenon, the size-cells of parent of it is 1, so I have set to zero? Jun 18 14:04:49 look at rstctl_pins example Jun 18 14:05:41 NishanthMenon, yes, but there is some different, I think doesn't have parent in DT Jun 18 14:05:46 the rstctl Jun 18 14:07:11 ayaka, am33xx_pinmux is the parent Jun 18 14:08:02 NishanthMenon, sorry, I mistake what I mean Jun 18 14:08:35 &rstctl is the child of the top level I think and rstctl_pins is the child of am33xx_pinmux Jun 18 14:08:58 ayaka, dont guess, look at am335x dtsi file Jun 18 14:09:15 sorry, the &rstctl is the child of the ocp Jun 18 14:09:29 yea, and so is am335x_pinmux Jun 18 14:09:39 what you are saying is a phandle to pin Jun 18 14:09:51 the pin has no arguments Jun 18 14:09:59 but ocp is the same level of am33xx_pinmux Jun 18 14:10:04 So? Jun 18 14:10:16 ideally it should have been inside ocp Jun 18 14:10:24 it really does not matter Jun 18 14:10:47 NishanthMenon, ok, maybe my kernel is a little out of time Jun 18 14:10:57 what we really should have (if we were to model hardware 100%) is to have syscon inside ocp, and pinmux inside syscon Jun 18 14:11:53 ayaka, your problem is pinctrl-0 -> that is pinctrl single a pin phandle with no parameters Jun 18 14:12:14 NishanthMenon, but with parameter I can't compile it Jun 18 14:13:47 NishanthMenon, sorry, it could be compile, what I have done ? Jun 18 14:15:57 ayaka, http://hastebin.com/hixuxisimi.diff builds fine on 3.16-rc1 Jun 18 14:17:55 NishanthMenon, it still doesn't work in 3.8 http://paste.fedoraproject.org/110780/01047140 I do that in am335x-boneblack.dts Jun 18 14:18:14 http://paste.fedoraproject.org/110781/01088140/ Jun 18 14:18:31 NishanthMenon, have you ever tested it in 3.16-rc1? could can1 work? Jun 18 14:18:47 ayaka, i dont use can Jun 18 14:18:51 sorry, the dcan1 of BBB, in system it is can0 Jun 18 14:18:54 no idea if it works Jun 18 14:19:38 I will test it Jun 18 14:20:21 I would try v3.8.13-backports Jun 18 14:21:08 ayaka, s/pinctrl-singel,pins/pinctrl-single,pins/g Jun 18 14:22:06 NishanthMenon, oh, thank you, how stupid I am Jun 18 14:22:18 ayaka, dont worry, happens all the time to me as well :) Jun 18 14:22:47 I am sorry, to waste you time to check this kind of problem Jun 18 14:23:21 http://paste.fedoraproject.org/110783/40310138/ a better result but not enough Jun 18 14:25:14 the return of devm_pinctrl_get_select_default is error Jun 18 14:32:12 ayaka, s/pinctrl-name/pinctrl-names/g Jun 18 14:34:09 NishanthMenon, it seems better but http://paste.fedoraproject.org/110786/02034140/ Jun 18 14:34:42 platform_get_resource failed Jun 18 14:34:51 yeah - now you are into can world Jun 18 14:35:00 what resource failed? Jun 18 14:35:08 NishanthMenon, http://paste.fedoraproject.org/110786/02034140/ Jun 18 14:35:35 I don't think this can driver could work, as there is no resource for it Jun 18 14:35:41 ayaka, i saw that :) - platform_get_resource of base address failed? Jun 18 14:35:50 or IRQ failed Jun 18 14:36:30 NishanthMenon, actually there is two failed here Jun 18 14:37:48 yeah - add some prints to the can driver and try to see where it failed Jun 18 14:38:01 NishanthMenon, I will Jun 18 14:38:16 have fun.. i need to sync out.. Jun 18 14:38:24 NishanthMenon, thank you Jun 18 14:38:28 ayaka, np Jun 18 14:56:59 res = platform_get_resource(pdev, IORESOURCE_MEM, 1); the res is NULL Jun 18 15:00:54 ,1 ? Jun 18 15:01:12 http://hastebin.com/agevilened.avrasm - there will only be a single resource ,0) Jun 18 15:01:23 so i think the driver is ok with that ,1 not being there Jun 18 15:01:52 but I do a test there, the res == NULL Jun 18 15:02:25 i think the driver is capable of handling two split regions, if the second region is not there, it cribs on log, but is handled.. i am just guessing Jun 18 15:02:54 if you have code for platform_get_resource(pdev, IORESOURCE_MEM, 0); that should be passing Jun 18 15:03:07 sorry, of course it would Jun 18 15:04:05 but should I change that 1 to 0? Jun 18 15:05:01 no Jun 18 15:05:09 there should be code to pick it from 0 Jun 18 15:05:19 the driver is probably functional at the log Jun 18 15:05:25 ignore the error message, i think Jun 18 15:05:32 i have'nt looked at the driver to comment better Jun 18 15:06:48 I would use my oscillograph to have a test Jun 18 15:11:59 NishanthMenon, thank you it seems work Jun 18 15:12:07 ayaka, cool :) Jun 18 15:14:27 but after I use cansend some data, the link would be down Jun 18 15:14:59 shall I connect it actually can network but not just oscillograph Jun 18 15:44:54 once it connect to real can network it works Jun 18 15:51:13 Good day people! Question here. I'm following the instructions for installing a driver on the BBB, and it says thtat the Angstrom requirements are kernel-dev, kernel-headers and task-native-sdk. What would be the equivalent for debian? Jun 18 17:14:23 The usual reference for kernel-related build questions for debian is this - http://kernel-handbook.alioth.debian.org/ch-common-tasks.html Jun 18 17:17:32 though the kernel shipped with the BBB isn't packaged like a typical debian kernel package. Jun 18 17:18:05 at least, the source is built with rcn's build scripts, not the source you get with "apt-get source linux" Jun 18 17:22:47 really quiet today... Jun 18 17:23:09 <_av500_> its the Fussball Jun 18 17:25:22 I see a VBUS error when booting with certain USB devices plugged in, kills USB until reboot. Is this a known problem, and is there a workaround? Jun 18 17:35:10 does anyone else have problems booting with certain usb devices plugged in? Jun 18 17:36:49 what kind of devices? Jun 18 17:37:50 One of my sandisk cruisers, a microsd reader, and a cellular modem. Jun 18 17:38:28 All the other devices I've tried have worked fine. I've also tried different kernels. Jun 18 17:38:50 and how much amps does your power source deliver? Jun 18 17:39:19 1A Jun 18 17:45:08 hi Jun 18 17:45:35 abferm: That is a little light. Jun 18 17:45:52 did anyone have this error "cannot locate cpu MHz in /proc/cpuinfo" on bbb+ubuntu12.04? Jun 18 17:51:39 duy_, i wouldn't really call it an error, the "BogoMips" value was ripped out of /proc/cpuinfo, because everyone miss-understood what it meant. Jun 18 17:53:49 duy_, https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9fc2105aeaaf56b0cf75296a84702d0f9e64437b Jun 18 18:01:39 I get VBUS errors during boot with certain usb devices plugged in at boot. When this happens the usb bus is unusable until I reboot the beaglebone without the device. The devices all work fine when plugged in after boot. Jun 18 18:02:08 rcn-ee... thanks! can you please advise step by step how to resolve this? Jun 18 18:03:08 I tested with several different kernels, and tried switching to a 2A power supply. Neither fixed the issue. Jun 18 18:03:55 hmm when you says devices...does that mean there is a hub? Jun 18 18:04:25 mythos: no, I only use a single device at a time Jun 18 18:06:04 are you sure that 2a supply can actually supply 2a? are you running the supply into either the 5v supply pins on the headers or the barrel jack? Jun 18 18:08:08 rcn-ee hello... I saw kernel has ability for the new 18xx t.i. wifi cape, am i assuming correctly this is working then? Jun 18 18:11:19 Barrel jack, and I'm pretty sure some of the devices I've tried that work draw more power than the ones that don't. Jun 18 18:41:06 I get this error: "musb-hdrc musb-hdrc.1.auto: VBUS_ERROR in a_wait_vrise (91, if it's failing on boot, then continupous power consumption isn't as much of an issue as the inrush to charge filter caps in the device Jun 18 18:45:25 why would that keep me from switching to a differnt device after boot? Jun 18 18:46:08 I am usining a kernel with working usb hotswap. Jun 18 19:08:34 mjgardes : It works with same power supply and an unpowered usbhub. Jun 18 19:55:18 Hi everyone I am hoping someone on here might be able to point me in the right direction. It seems like the usb port on my beaglebone is no longer powering anything plugged into it? Has anyone seen this before? Jun 18 19:55:59 it is a beaglebone back rev c by the way Jun 18 19:56:37 hello, does anybody here know how to flash / load a new kernel to the beaglebone black? I've been stuck on the "access the uboot console" step for days Jun 18 19:58:47 MrYaah: as in you can't get a serial connection? Jun 18 19:59:26 I can Jun 18 19:59:31 but its always to just the regular bash terminal Jun 18 19:59:42 I'm plugging it in via the included usb cable Jun 18 19:59:54 rbaxter: have you rebooted your board? Jun 18 20:00:02 heres the guide I've been following http://elinux.org/Building_BBB_Kernel Jun 18 20:00:24 it says to press the spacebar repeatedly to get it to stop on uboot, I plugged in a usb keyboard and used that to press space while powering it up Jun 18 20:00:28 but it doesn't seem to do anything Jun 18 20:01:06 MrYaah, Press the "space bar" on your host pc, not the usb keyboard attached to the beagle.. Jun 18 20:01:24 oh Jun 18 20:01:26 ok Jun 18 20:01:28 ill try that Jun 18 20:01:50 thanks rcn-ee Jun 18 20:02:06 @tbr what do u mean by reboot the board? Jun 18 20:02:23 rbaxter: well, did you restart it? Jun 18 20:03:05 ok I think im still doing it wrong Jun 18 20:03:15 i'm going to try doing it on my mac Jun 18 20:03:32 @tbr yes I unplugged the usb cord that is providing power to it Jun 18 20:03:42 Hi Jun 18 20:03:47 rbaxter: so you are only powering it from USB? Jun 18 20:03:52 yes Jun 18 20:03:52 is anybody here? Jun 18 20:03:56 nope Jun 18 20:03:59 I have a question Jun 18 20:04:16 I am new to embedded linux Jun 18 20:04:36 rbaxter: if you are planning to connect USB devices, I'd recommend to use a proper power supply connected through the barrel connector Jun 18 20:05:09 tbr: why did it work before then? Jun 18 20:05:25 just wnat to know about Mini2440 Jun 18 20:05:32 rbaxter: not sure, but with USB power you won't get very far Jun 18 20:05:45 in comparison to BeagleBone Black Jun 18 20:06:22 slava, let me guess.. which book are you reading? the Mini2440 is only 10 years older. ;) Jun 18 20:06:23 slava: Well, this channel does not necessarily know anything about the mini2440 since that is not under the scope of the channel. Jun 18 20:06:38 ok Jun 18 20:06:56 are there good instructions step by step how to start? Jun 18 20:07:02 in BeagleBone Black Jun 18 20:07:21 tbr: thanks i will try that Jun 18 20:07:21 slava, "start what"... it's linux, so everything is a possibility.. Jun 18 20:07:31 hi; trying to use a USB-A to Serial with BBBrC Jun 18 20:07:59 ok, thanks Jun 18 20:08:07 rbaxter: it's possible that there is another explanation, but if you plan to use external USB devices it's recommended to use a proper power supply. Jun 18 20:08:50 rbaxter, it's a usb power spec issue.. On powerup, your limited to 100mA, exceed that and it shutsdown.. Jun 18 20:11:03 Any suggestions on how to use a USB-A to Serial with BBBrC ? Jun 18 20:11:12 Yes. Jun 18 20:11:15 Correctly. Jun 18 20:11:21 ;) Jun 18 20:11:41 that would be a "how well" query Jun 18 20:11:59 plug it in? follow manual, they have pretty pictures.. Jun 18 20:11:59 Lee_: YOu have not provided sufficient information in your query for any meaningful response. Please rephrase and add information. Jun 18 20:12:05 im asking a "how to" Jun 18 20:12:13 ok...just a sec Jun 18 20:13:09 tbr: do you have recommendations of a good one to order online? Jun 18 20:13:16 I have a USB-A to Serial connected via USB to the BBBrC and the Serial side connected to a REACH Touch SCreen Jun 18 20:13:42 Lee_, /dev/ttyUSB? Jun 18 20:13:47 Lee_: OK, and what issue are you having with it? Jun 18 20:13:49 jkridner: rbaxter its still not working :/ Jun 18 20:14:06 I need to send acscii commands back and forth using something like minicom Jun 18 20:14:11 MrYaah, which "serial" terminal are you using? Jun 18 20:14:14 so im literally just plugging the beaglebone black into my computer and then spamming the space bar Jun 18 20:14:20 rbaxter: I usually use whatever I have around in 5V and around 2A power supplies. you might also want to check on what rcn-ee said. Another option might be a powered usb hub. Jun 18 20:14:25 im using python -m serial.tools.miniterm Jun 18 20:14:27 not sure if its ttyUSB or ttyGS0 Jun 18 20:14:32 and connecting to /dev/cu.usbmodem1413 Jun 18 20:14:41 Lee_: Which one exists on your system? Jun 18 20:14:44 Lee_: Which one works? Jun 18 20:14:50 Lee_: Use that one. Jun 18 20:14:50 Lee_, well pull it out, "dmesg" plug in, "dmesg" it'll tell you.. Jun 18 20:15:15 MrYaah, use gtkterm, or cutecom.. Jun 18 20:15:18 ah..will try that Jun 18 20:20:17 dmesg indicated no difference :( Jun 18 20:21:28 really? no difference.. then usb must be broken.. it should atleast come up with device id: or something.. Jun 18 20:22:20 the USB-A end is in the USB "Host" or standard USB not the miniUSB Jun 18 20:23:41 As it ought to be, yes. Jun 18 20:40:59 ok.im using ttyUSB0...I need to test it for a serial over USB connection Jun 18 20:41:45 rcn-ee are still there? Jun 18 20:42:58 so connect via: /dev/ttyUSB0 there's lots of serial packed languages, from screen, phython, etc.. Jun 18 20:44:18 ok Jun 18 20:44:26 rcn-ee: I've installed CuteCom Jun 18 20:45:22 so now when you type something in the "text" box on bootup, it should stop u-boot.. Jun 18 20:45:33 RCN-EE: like screen /dev/ttyUSB0 115200 ??? Jun 18 20:45:36 (althougth with cutecom, you need to press the button) Jun 18 20:46:08 I am trying to get uhd compiled using scratchbox2, on my arm rootfs, with the arm-linux-gnueabihf cross compiler, and it seems to be just as slow as if I were to natively compiling it. What could I be doing wrong? Jun 18 20:46:12 rcn-ee: it wont let me type anything in the input text box and when i try to click open device it says "Could not open /dev/cu.usbserial Jun 18 20:46:42 MrYaah, are you part of the "dialout" group? Jun 18 20:47:04 nopep Jun 18 20:47:35 well you need that in debian/ubuntu... you could always try doing it as root, if you don't want to change your account.. Jun 18 20:51:22 ahem, is the ethernet eeprom programmed on the beagleboard (xM)? Jun 18 20:51:39 ethtool -e eth0 gives me 0x0000 for the whole eeprom Jun 18 20:51:53 MrYaah, ah.. your on a Mac... No idea on which terminal program works there.. Jun 18 20:52:17 jonand, xM didn't have any mac address programmed.. Jun 18 20:53:03 rcn-ee: okay, thanks. Jun 18 20:55:04 ok Jun 18 20:55:06 yea Jun 18 20:55:13 rcn-ee: I'm going to just try using arch linux Jun 18 20:55:18 which is what I was using before Jun 18 20:55:27 I have a usb device that works when I boot with it plugged into an unpowered hub, but not when I boot with it plugged directly into the BBB. I get a vbus error during boot when directly connected, and the usb will no longer enumerate new devices. I am using a 2A power supply. I do not want to always have the usb hub plugged in, and I would like my usb device to be there before boot. Jun 18 20:56:10 and im going to try gtk term Jun 18 20:56:39 I was able to use cutecom to reconnect to the beaglebone on /dev/ttyACM0 Jun 18 20:56:53 but as soon as I restarted it it closed the connection and I couldn't press space while it was booting up Jun 18 20:58:17 odd, i spent a lot of time debugging the beaglebone, and normally just hit the reset button, and never lost my usb/gtkterm... Jun 18 20:59:20 maybe I havn't set it up properly Jun 18 20:59:28 what os are you using Jun 18 20:59:31 version and everything Jun 18 20:59:40 debian testing.. ;) Jun 18 20:59:51 blah Jun 18 21:01:17 and you're using Jun 18 21:01:22 the usb to usb mini connector Jun 18 21:01:28 not usb to ftdi Jun 18 21:02:34 well on the beaglebone (white) it's a built-in usb-ftdi over the otg connector. On the black, i set it up to be a gadget serial driver, so on reboot you lose the usb connection, unless you use a 3.3v ftdi usb serial on the internal header.. Jun 18 21:03:14 I don't understand what that means >_< Jun 18 21:04:19 Well, one reason the white costs more then the black, it has a built-in usb-ftdi serial convertor internally connected to ttyO0 and connected to a hub on the otg port so you can access it via the otg usb connector. Jun 18 21:05:02 so inorder to access the uboot serial I do need the ftdi usb serial cable? Jun 18 21:05:05 on the black Jun 18 21:05:56 is there any other ways to install the new kernel other than through uboot's tftp thing? Jun 18 21:05:59 Correct... There are "other" 3.3v serial/usb convertors you can use too. Jun 18 21:06:00 are there* Jun 18 21:06:18 Ah.. use a microSD card and copy the files from your build system? Jun 18 21:06:59 only the "eMMC" is a pain to update, the microSD is too easy; http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-CopyKernelFiles Jun 18 21:10:31 Part of what is making this so hard to figure out is I've never messed with the kernel before on anything and I barely even know what I'm trying to accomplish in this case Jun 18 21:10:54 My boss just wants me to figure out how to compile the beaglebone kernel from scratch and install it so that we can tweek it as we see fit Jun 18 21:11:36 well... start from the top: http://eewiki.net/display/linuxonarm/BeagleBone+Black and pick up the $20 usb-serial ftdi cable.. Jun 18 21:11:52 Mr.Yaah: That's not too difficult if you can follow Robert's wiki Jun 18 21:12:04 There's a link to it from rcn-ee Jun 18 21:23:23 what would you guys recommend for an arm board than can function as a home theater and web server Jun 18 21:24:42 novena Jun 18 21:25:00 * mjgardes ducks Jun 18 21:25:43 I was about to say xbox :P Jun 18 21:27:17 obvious a roku inside a QNAP.. ;) Jun 18 21:30:00 would it be possible to cut open a usb cable and create the ftdi end of it by hand? Jun 18 21:30:04 I think we might have the materials Jun 18 21:32:51 Sure... why not, it's fairy land.. atleast it's a small package: http://www.ftdichip.com/Products/ICs/FT230X.html Jun 18 21:33:30 hey rcn-ee Jun 18 21:33:32 MrYaah you are more likeley to have an ftdi adapter laying around already than the materials to make one. The company that makes the chip in them is pretty proud of them and charges an arm and a leg. Jun 18 21:33:49 ooh Jun 18 21:34:06 hi mrpacket_ i didn't do it! Jun 18 21:34:12 ha ha Jun 18 21:36:10 Question: I have a qt creator all setup and connected to my BBB. I built a test app. but when I go to deploy it says remote file system has 0 megabytes of freespace and 5 is required. i df the BBB file system and sure anough it looks full. Jun 18 21:37:05 I see a statement, not a question. Jun 18 21:37:59 sorry I followed a tutorial to a T on a fresh BBB and I’m having a hard time figuring out why the file system is full Jun 18 21:38:28 have you installed any software on it or anything? Jun 18 21:39:12 alrighty well, I'm just going to buy that and set up the build environment and other stuff in the meantime Jun 18 21:39:19 i push an embedded qt library to it according to my tutorial, i think that was basically it. Jun 18 21:41:26 that is odd, are you running from the onboard storage or an sdcard? Jun 18 21:41:27 ty for the help rcn-ee Jun 18 21:41:28 rcn-ee: is the t.i. 18xx wifi cape usable in new debian kernel Jun 18 21:42:05 i am running from the onboard storage no sd inserted. Jun 18 21:43:38 try setting up an sdcard to run from for some space, or poke around to find out where all your space went. Jun 18 21:45:20 im poking around now here is the df http://imgur.com/0YJRYkm Jun 18 21:46:15 mavmr2_, yeap you ran out of the 2GB of space. Jun 18 21:46:35 uninstall what you don't need.. Jun 18 21:46:35 ok ill have to trace my steps to see what happened i guess Jun 18 21:47:01 dogrocket, i have one.. it's still in the bag.. someone posted a patch for v3.8.x but it broke everything else.. Jun 18 21:49:55 O.o Jun 18 21:51:50 ok.. well at least some folks are looking at it, havent bought one yet so no harm, i like fact it uses the prus to offload some of work from cpu, not sure if other wifi chips do that Jun 18 21:53:52 dogrocket, the 4 patches are still here: https://github.com/beagleboard/kernel/pull/92 Jun 18 21:54:38 rcn-ee thanks will check it out Jun 18 22:10:07 I'm moving a custom cape from Angstrom to debian on a BeagleBone Black and the debian dist recognizes the cape and then says that the dtbo file wasn't loaded, any one have any experience with this kind of issue? Jun 18 22:11:28 gwilson: pastebin the dmesg log Jun 18 22:11:35 should be easy enough to track down .. Jun 18 22:19:58 What is the best way to power BeagleBone Black with a battery to use USB? Jun 18 22:29:57 hi Jun 18 22:30:20 what is the best system operative for beaglebone? Jun 18 22:31:30 hi Jun 18 22:31:53 maycol: Depends on what you’re trying to do. Jun 18 22:31:54 jkridner:pastebin to http://pastebin.com/2yTcCsh6 Jun 18 22:32:28 I need control camara web por ip Jun 18 22:32:49 maycol: a webcam? Jun 18 22:32:54 yes Jun 18 22:33:10 for un bobot explore Jun 18 22:33:28 Sorry haven’t hooked up a camera to a BB myself. Jun 18 22:34:59 aom: You want to power a BB with batteries and have the BeagleBone and use it to power an accessory over the BeagleBone’s USB host port? Jun 18 22:36:01 I want add a camara to robot and control for radio frecuency RF Jun 18 22:36:45 any camera Jun 18 22:37:18 maycol: I’d check the web for people who’ve done that, and see what setup they were using. Jun 18 22:38:09 ubunto or anstron, wich os these has more information? Jun 18 22:38:54 improvnerd: yes USB host port Jun 18 22:42:46 aom: You can do something as simple as throw 5 or 6 AA batteries together and use a 7805 voltage regulator. Jun 18 22:44:52 aom: Looks like there’s at least one battery cape, as well: http://elinux.org/Beagleboard:BeagleBone_Battery Jun 18 22:48:48 improvnerd: thanks, weight is important to me, I have an 11v battery Jun 18 22:49:33 ubunto, debian or anstron? what is favorite with more information? Jun 18 22:49:49 aom: You can use an 11v battery with a 7805 as well, but it will get kind of hot. There are smarter voltage regulators on the market now, but I don’t know much about them. Jun 18 22:50:19 aom: In my experience, BeagleBone is a lot more fussy about power than, say, an Arduino. Jun 18 22:50:54 yes, arduino is very easy Jun 18 22:52:59 maycol: Angstrom used to be the pre-installed OS on BeagleBone, but it’s switching to Ubuntu, IIRC. Jun 18 22:53:14 improvnerd: so maybe the best why to go with something like this: https://www.adafruit.com/products/1385 Jun 18 22:56:03 improvnerd, debian. ;) Jun 18 22:56:06 but close Jun 18 22:58:15 rcn-ee: Thanks for the correction. Jun 18 22:59:10 aom: Looks interesting. Only problem might be that it’s a little noisier. No idea if that will be a problem. Jun 18 23:00:56 don't use an old 7805, use somethign like: http://www.digikey.com/product-search/en?v=102&FV=fff40042%2Cfff800df&k=7805&mnonly=0&newproducts=0&ColumnSort=0&page=1&stock=1&quantity=0&ptm=0&fid=0&pageSize=25 (it's a switcher, good to 20v input) Jun 18 23:11:19 I think there's a 3A version of the 7805 isn't there? or am I thinking of another old-skool regulator ... Jun 18 23:11:36 everything I do is now switchers unless its retro-fit lol Jun 18 23:13:56 My only foray into battery-powered BeagleBone was this: Jun 18 23:14:29 http://o-botics.org/robots/quickbot/mooc/v1/ Jun 18 23:15:08 It used a 7805 regulator because the core concepts of the robot were “stupid simple” and “no soldering”. Jun 18 23:21:12 if it's too noisy what effect on i2c Jun 18 23:37:29 improvnerd, but they are so in-efficient, those modules are drop in replacments for the 7805 pinout, no external devices.. Jun 18 23:50:41 rcn-ee: I’ve investigated such things, but haven’t had a chance to try one out. I wanted to limit my response to approaches I had used myself that had worked. Jun 19 01:58:48 Can someone explain how you create software packages (RPM equivalent) for a beaglebox **** ENDING LOGGING AT Thu Jun 19 02:59:59 2014
