**** BEGIN LOGGING AT Wed Jun 24 02:59:58 2015 Jun 24 03:49:27 i am new to beaglebone..since some days i am trying to connect my beaglebone rev a6 with my laptop (win 8.1) Jun 24 03:49:54 but not able toconnect it with 192.168.7.2 Jun 24 05:26:25 hi all. has anyone of you made experiences in using PTP and the BBB? Jun 24 05:55:17 precision time protocol? Jun 24 05:56:08 the photo thing Jun 24 05:56:16 usb Jun 24 05:56:23 maybe Jun 24 05:56:29 People Terrorizing PAsta Jun 24 05:56:44 * LetoThe2nd loves TLAs Jun 24 05:57:03 People Toasting Pi Jun 24 05:57:09 people trolling people Jun 24 06:25:00 hi there Jun 24 06:39:17 hello sir Jun 24 06:41:11 are you there?? i have some doubt regarding Beagleboard-xM Jun 24 06:45:24 Arvind_: ask Jun 24 06:45:27 dont ask to ask Jun 24 06:48:16 is this board support windows 7 Jun 24 06:52:15 Arvind_: windows 7 running on the bpard? Jun 24 06:52:17 board Jun 24 06:52:18 no Jun 24 06:52:59 you can connect it to a windows 7 system though. If it runs the right software Jun 24 06:58:29 sir for this which driver it requires Jun 24 07:00:42 drivers? Jun 24 07:00:46 you dont need drivers Jun 24 07:01:05 if you connect the BBB to ethernet, you can talk to it over the network Jun 24 07:04:25 gee, he could have just read the bb.org pages... Jun 24 07:18:55 tbr sorry - was afk - yes precision time Jun 24 07:19:07 I need to sync the time of my bbb with the time of my laptop Jun 24 07:19:09 :/ Jun 24 07:19:19 on the bbb is debian installed and on my laptop ubuntu Jun 24 07:21:53 sla89: You can either use NTP (install ntpd on laptop) or tlsdate. Tlsdate will set time by issuing a https request towards your laptop (requires a webserver with SSL enabled) Jun 24 07:22:19 Chrille how is the precision of tlsdate Jun 24 07:22:24 and ntp? Jun 24 07:22:42 sla89: tlsdate is 1 second, ntp is fraction of a second Jun 24 07:23:01 ntp is the normal way to do things Jun 24 07:23:22 if you want to use ptp, you'd better have good reasons Jun 24 07:38:11 Chrille okay Jun 24 07:38:24 Chrille and when I need precision < 1m? Jun 24 07:38:26 Chrille and when I need precision < 1ms? Jun 24 07:39:35 i have NTP now running with an offset of 80 ms Jun 24 07:39:35 sla89: Try reading http://www.ntp.org/ntpfaq/NTP-s-sw-clocks-quality.htm about NTP precision Jun 24 07:39:57 You can easily get better than 1 ms with NTP Jun 24 07:41:25 nettime synchro under 1ms why would one need this? Jun 24 07:44:15 maybe he wants to put it into a particle accelerator experiment ;) Jun 24 07:45:39 i need to do some one-way network measurement Jun 24 07:45:52 therefore i need to take time on my laptop and bbb Jun 24 07:45:53 ? Jun 24 07:45:56 and compare those Jun 24 07:46:07 udp? Jun 24 07:46:10 RTT does not say anything in my case Jun 24 07:46:25 udp? Jun 24 07:46:33 i dont have to measure time differences Jun 24 07:46:43 i have to measure the needed time from host a to host b (latency) Jun 24 07:47:02 for my own protocol Jun 24 07:47:33 I cannot add a timestamp to my protocol since this would falsify my measurement Jun 24 07:54:52 sla89 hm okay Jun 24 07:55:23 but network traffic under 1ms even in local lan is not likely to take place Jun 24 07:55:55 woglinde I know that Jun 24 07:57:00 okay Jun 24 07:58:16 wogline maybe I wasn't clear enough in my description. I have to do some network measurements in one direction (host A to host B). Before the packet is sent with the specific data the system time is stored in memory. On system B the system time is taken when the packet received and was processed and also stored in memory. This is going to happen for about 5 minutes. Afterwards I can compare the times and the difference between time A a Jun 24 07:58:18 per packet Jun 24 07:58:54 Everything would be easy, if I can measure the RTT, but in my scenario the RTT does not say anything about the latency. Jun 24 07:59:16 RTT is equal to ping - Packet goes from host a to b and back to a Jun 24 07:59:25 and when it was sent and received by A the time is taken Jun 24 08:02:53 woglinde: ptp acheives <1ms sync Jun 24 08:03:31 woglinde: i think, w/o special hardware it's around a few 10us to 100us Jun 24 08:03:43 woglinde: with real hardware [tm] you can get it down to 100ns Jun 24 08:04:24 sla89: are you trying to do ptp by hand? if so, stop. you will not be able to beat it Jun 24 08:04:41 nope - I am not Jun 24 08:05:15 ah.. sorry, i misread what you wrote Jun 24 08:05:18 Its a students project where the BBB is used to control a small robot via wifi Jun 24 08:05:29 eh.. Jun 24 08:05:33 and one requirement is to measure the latency for the commands sent via wifi Jun 24 08:05:44 so, use a wire Jun 24 08:05:44 no problem :) Jun 24 08:05:46 i hope you run ptp over wire? Jun 24 08:05:59 I am not running PTP at all at the moment ^^ Jun 24 08:06:22 you dont need PTP Jun 24 08:06:34 the idea was to sync the time before the measurements were done via a cross over wire Jun 24 08:06:35 run a GPIO between host and robot Jun 24 08:07:05 set gpio high when you send a packet Jun 24 08:07:15 measure the delta on the other side Jun 24 08:07:17 move on Jun 24 08:07:26 what av500 said Jun 24 08:07:30 far simpler Jun 24 08:07:46 never done this before Jun 24 08:07:47 and with a good oscilloscope you can readily measure delay down to 100ns Jun 24 08:07:56 how can I achieve it in detail? Jun 24 08:07:59 actually, you can do that even with a cheap scope Jun 24 08:08:05 how can i put gpio high with my laptop Jun 24 08:08:13 use the parallel port :) Jun 24 08:08:22 +1 Jun 24 08:08:49 or then NumLock LED Jun 24 08:08:51 the* Jun 24 08:10:07 to verify you can sniff the packets off the air using gnuradio and some sdr Jun 24 08:10:09 i dont have :( Jun 24 08:10:47 you dont have a numlock LED? Jun 24 08:12:00 i have no parallel port on my laptop Jun 24 08:12:06 but i have a numlock led Jun 24 08:12:20 KotH thanks for the hint Jun 24 08:12:45 serial port Jun 24 08:12:46 whatever Jun 24 08:12:54 he dont have that either Jun 24 08:13:05 he has a laptop, not a museum piece Jun 24 08:13:12 then use a machine/board that has :) Jun 24 08:13:42 KotH can I sniff all packets with gnuradio? does it fetch everything around? Jun 24 08:15:03 sla89: ignore the gnuradio for now Jun 24 08:15:07 you dont have that either Jun 24 08:16:03 :( Jun 24 08:16:24 is it possible via USB? Jun 24 08:16:40 sla89: why not measure RTT and half it? Jun 24 08:16:51 because its not the same Jun 24 08:17:08 when the packet is on its way back some jitter can happen or other stuff Jun 24 08:18:02 that can happen in the other direction too Jun 24 08:18:05 no? Jun 24 08:18:28 yeah Jun 24 08:18:41 but assume sending from A to B needs 10 ms Jun 24 08:18:49 back from B to A 7 ms Jun 24 08:18:52 would be 17 MS Jun 24 08:18:53 right Jun 24 08:18:58 it would Jun 24 08:19:04 you cannot half it - its not the same Jun 24 08:19:14 well, then do this: Jun 24 08:19:25 on the PC, make numlock light up when you send the packet Jun 24 08:19:35 on the BBB make some GPIO light up when you recieve it Jun 24 08:19:41 hook both to a scope Jun 24 08:20:19 then you can see the delta Jun 24 08:20:20 use two bbbs, see, you can use two gpios. :-) Jun 24 08:21:40 av500 itsnt it a bit inaccurate? Jun 24 08:21:47 why? Jun 24 08:22:08 LetoThe2nd hehe - that doesn't fit to the setup since the controlling part is a laptop or smartphone - not another bbb ;) Jun 24 08:22:43 on the phone, make a part of the screen go white from black Jun 24 08:22:47 put a photocell there Jun 24 08:22:53 same as on the LED Jun 24 08:23:01 since I would then measure lights coming up and down - how shall I take the time of this? Jun 24 08:23:14 you see the time on the scope Jun 24 08:23:19 the X axis is time Jun 24 08:23:23 even quite calibrated Jun 24 08:23:50 Hi - I'm trying to load ARM's C compiler with NEON stuff but it's too big for the free space on my BBB. Any suggestions? Jun 24 08:24:00 * LetoThe2nd doesn't get the point. you want to make the network, so better get two endpoints that can provide the data you need. 2xbbb + a scope or logic analyzer. logic analyzer can even be running on some laptop or phone and see: results are there. Jun 24 08:25:08 sla89: you do understand that you can show the timing relation between 2 signals on a scope? Jun 24 08:26:20 Peter___: "ARMs C compiler with NEON stuff"? in what form is that meant to be different from the gcc that comes with the stock installaion? Jun 24 08:26:57 Good question, but I found a page that compared the machine code and said ARM's was better Jun 24 08:27:34 Peter___: well the general answer for the lack of space problem is: add more storage. :-) Jun 24 08:27:43 or, in reverse: free up some space. Jun 24 08:28:04 Peter___: but if you're talking about ARMCC, be assured: its crap. Jun 24 08:28:06 I also can't get the kind of speed we need from gcc, even using -O3 and the approprrate flage at compile and link Jun 24 08:28:26 and ARM compiler has unicorns inside? Jun 24 08:28:34 and make your code magically fasdter? Jun 24 08:28:37 Why do you say ARMGCC is crap? Jun 24 08:28:45 Peter___: in about 100 of 100 cases, its not the compiler that makes your code slow, its the code that makes the code slow. Jun 24 08:28:46 its not crap Jun 24 08:28:51 but its also not magical Jun 24 08:29:15 I'm running the same sode on my old PC and on the BBB - the PC is 15 times faster Jun 24 08:29:19 code Jun 24 08:29:20 of course Jun 24 08:29:40 Peter___: read more precisely what i said. i said: "ARMCC is crap". no letter 'G' in there. and its crap because its an ancient compiler frontend on an even more ancient backend. Jun 24 08:29:42 thats not surprising Jun 24 08:29:51 I don't feel gcc is using the BBB's resorces Jun 24 08:29:59 like? Jun 24 08:30:03 what does your code do? Jun 24 08:30:08 av500 nope - didnt got it how I can achieve this. I was thinking about it but I don't get it :( Jun 24 08:30:23 sla89: you see 2 signals on a 2-channel scope Jun 24 08:30:25 sla89: ask your instructor to show you how a scope works :) Jun 24 08:30:28 one goes high at time t_1 Jun 24 08:30:34 the other at time t_2 Jun 24 08:30:38 you trigger on signal 1 Jun 24 08:30:49 then you move the cursor to be on t1 and t2 Jun 24 08:30:55 yeah - I know that Jun 24 08:30:55 it just calculates atan2(y,x) over 100 different values for y and x Jun 24 08:30:57 and the scope tells you the delta Jun 24 08:31:20 ah Jun 24 08:31:28 Peter___: the BBB has no atan in hardware Jun 24 08:31:30 and i switch the LEDs of immediatly Jun 24 08:31:37 it uses the floating point lib that comes with gcc Jun 24 08:31:49 since I will receive/send several packets Jun 24 08:31:53 sure Jun 24 08:32:08 if you do it continously you can overlay all the traces Jun 24 08:32:15 then you even see the min/max latency Jun 24 08:32:30 OK - so we have to rewrite all these functions for NEON? Jun 24 08:32:31 the armcc one might be a feq cycles faster Jun 24 08:32:47 yes Jun 24 08:33:08 http://stackoverflow.com/questions/18187492/calculate-atan2-using-simd-instructions-and-neon-arm-assemlby Jun 24 08:33:14 the compiler wont do that for you Jun 24 08:33:53 av500: hm, shouldn't -gnueabihf be able to use the floating functions automagically to build atan out of them? Jun 24 08:34:09 e.g. the problem is only "constructed atan" versus "hw atan" Jun 24 08:34:31 the only speedup is if you do SIMD Jun 24 08:34:42 otherwise, yes gcc will emit floating point code Jun 24 08:34:53 very much like armcc or on the PC Jun 24 08:35:17 thanks for confirming :) Jun 24 08:35:40 OK, thanks for explaining. We weren't sure what we would get with the Arm version of the compiler. Jun 24 08:36:23 Peter___: not 15x faster Jun 24 08:36:40 is armcc free to use now? Jun 24 08:36:45 nope Jun 24 08:36:49 well, how much faster? Jun 24 08:36:55 simple Jun 24 08:36:58 it .... depends Jun 24 08:37:00 only for <32kB baremetal Jun 24 08:37:04 on everysingle use case Jun 24 08:37:21 do not use atan at all haha Jun 24 08:37:28 but optimizing your code faster will be always better Jun 24 08:37:32 dont use atan Jun 24 08:37:33 well, how much faster would you think Jun 24 08:37:36 use a look up table Jun 24 08:37:38 woglinde: that basically solves it Jun 24 08:37:45 Peter___: I cannot say Jun 24 08:37:45 av500: dang you typed faster. Jun 24 08:37:48 nobody can Jun 24 08:38:02 its the usual tradeoff storage/speed? Jun 24 08:38:04 :-) Jun 24 08:39:02 its one solution Jun 24 08:39:06 look up table Jun 24 08:39:10 approximation Jun 24 08:39:18 changing the math to another "domain" Jun 24 08:39:27 av500 thank you for your help - I think this can do the trick :) Jun 24 08:39:33 it all depends/tm) Jun 24 08:39:35 it all depends(tm) Jun 24 08:39:44 LetoThe2nd thank you too :) Jun 24 08:41:19 sla89: np :) Jun 24 08:44:48 why is he named like a TI data sheet? Jun 24 08:49:29 who? Jun 24 08:49:45 you :) Jun 24 08:50:15 http://electronics.stackexchange.com/questions/14297/ti-manual-naming-conventions Jun 24 08:50:42 omg xD Jun 24 08:50:50 it has nothing to do with TI ;) Jun 24 08:50:59 the letters are part of my real name ^^ Jun 24 08:51:06 ;) Jun 24 08:51:11 and you are 89 years old? Jun 24 08:51:34 born 89? Jun 24 08:51:49 more likely Jun 24 08:52:05 don't discriminate against old people Jun 24 08:52:09 yeah - born 89 Jun 24 08:52:10 hehe Jun 24 08:52:28 equal chances and all that stuff Jun 24 08:53:27 does the BBB throttle the cpu speed if it is plugged to USB since it does not get enough power? Jun 24 08:53:40 especially if also a wifi dongle is used Jun 24 08:55:23 nope Jun 24 08:56:21 why do people then write to use 5V and 2A when running BBB with a wifi dongle? Jun 24 08:56:29 Yes it does as far as I know Jun 24 08:57:12 sla89: because it will just fail and crash and burn Jun 24 08:57:23 sla89: if you don't Jun 24 08:57:26 because it would exceed the power draw from the USB port Jun 24 08:58:18 that's not really managed Jun 24 08:58:38 but yes Jun 24 08:58:52 basically it would cause the voltage to drop and then things to stop working Jun 24 08:59:06 ah alright Jun 24 08:59:08 thanks :) Jun 24 09:00:54 the BBB is also limited to 500 Mhz when running on USB Jun 24 09:01:18 ? Jun 24 09:01:25 Attunga: since when Jun 24 09:01:38 that must be a fairly new feature Jun 24 09:01:39 since I read it ages ago Jun 24 09:02:01 when i was using it few months ago it would run at full speed regardless of the power source Jun 24 09:59:37 av500: yes, with GR you can sniff all packets in a channel. actually, you can sniff multiple networks that lie within the frequency range you capture Jun 24 09:59:56 av500: just makes analysis more difficult :) Jun 24 10:07:54 KotH: I know you can Jun 24 10:08:04 but one does not usually have GR Jun 24 10:09:56 av500: you can get The GR from github, like with all other code Jun 24 10:10:27 you can even clone one rtl-sdr dongle, if you need to Jun 24 12:28:15 Hello Jun 24 12:28:33 need help setting time on beaglebone black Jun 24 12:29:53 timedatectl command doesn't work Jun 24 12:32:46 bbb has no rtc Jun 24 12:32:53 use the date command Jun 24 12:32:57 man date Jun 24 12:33:16 or if you want and have a network connection install a ntpd Jun 24 12:33:28 to get the correct time over the net Jun 24 12:34:03 how can I install ntpd Jun 24 12:34:24 apt-get ? if you have installed debian or ubuntu Jun 24 12:34:41 I have debian Jun 24 12:38:25 woglinde: actually, the SoC has RTC but there is no battery Jun 24 12:39:07 jacekowski okay okay Jun 24 12:39:33 i remember someone here a while back who got the RTC working on the BBB Jun 24 12:43:19 i got ntpd working Jun 24 12:43:31 on my bbb Jun 24 12:43:36 for testing purpose Jun 24 12:44:04 normaly you just need to enter sudo apt-get install ntp Jun 24 12:44:11 in your command line Jun 24 12:44:17 thanks Jun 24 12:44:39 I've also heard that someone figured out a way to solder a battery on to keep the RTC ticking but I have yet to find any proof. Jun 24 12:44:40 and setup the configuration at /etc/ntp.conf Jun 24 12:44:43 most common rtc chips are just i2c devices, almost trivial to configure. but they won't be managed by timedatectl because it relies on /dev/rtc0 which is the internal, non-battery backed-up rtc Jun 24 12:45:38 sla89 did you get error when you did yours Jun 24 12:45:40 search for a ntp server near to your location - you can find the addresses here http://www.pool.ntp.org/ Jun 24 12:45:54 Ibrahim no - not really - what is the error you get? Jun 24 12:45:55 my is coming up with an error Jun 24 12:46:14 dpkg: error processing llvm-3.0-dev (--configure Jun 24 12:47:07 try sudo apt-get update Jun 24 12:47:09 first Jun 24 12:47:11 Errors were encountered while processing: ntp; binfmt-support; llvm-3.0-runtime llvm-runtime; llvm-3.0 llvm; llvm-3.0-dev; Jun 24 12:47:57 is it a blank BBB? fresh installed everything? Jun 24 12:48:24 have you installed llvm? Jun 24 12:49:40 i have using sudo apt-get install llvm clang Jun 24 12:49:51 before? Jun 24 12:50:09 did you get any error while installing llvm and clang? Jun 24 12:50:17 Yes, Jun 24 12:50:30 Hope I have messed up somewhere Jun 24 12:50:39 tried to man thingd Jun 24 12:51:02 do you have installed the build essentials? Jun 24 12:53:14 and why dont you use gcc? Jun 24 12:53:30 (i am only interested why - dont want you to remove it) Jun 24 12:54:24 actually Jun 24 12:55:02 same error as when I am trying to install ntp Jun 24 12:56:04 Is the bone connected to a network? Jun 24 12:56:11 Can the bone talk to the Internet? Jun 24 12:56:21 Yes Jun 24 12:56:31 Have you done 'apt-get update' successfully, without error? Jun 24 12:56:46 I have managed ping, clone files ec Jun 24 12:57:27 its strange llvm bails out at dpkg-configure Jun 24 12:57:44 woglinde: Well, we also are missing the rest of the error. Jun 24 12:57:59 Ibrahim try apt-get remove the llvm stuff for now Jun 24 12:58:45 curretly running apt-get update again Jun 24 12:58:59 someone was interested in low power shutdown on beaglebone? Jun 24 12:59:20 got the following replies Jun 24 12:59:59 W: There is no public key available for the following key IDs: 9D6D8F6BC857C906; W: There is no public key available for the following key IDs: 7638D0442B90D010; W: There is no public key available for the following key IDs: 7638D0442B90D010 Jun 24 13:00:31 Ibrahim: What mirror are you using? Jun 24 13:00:43 you have performed apt-get update? Jun 24 13:01:41 08:58 < Ibrahim> curretly running apt-get update again Jun 24 13:01:42 i did Jun 24 13:01:50 sla89: And Ibrahim has broken GPG.

Jun 24 13:03:51 llvm? Jun 24 13:04:15 No, the server you download your packages from./ Jun 24 13:04:27 Configured in /etc/apt/sources.list Jun 24 13:04:42 github Jun 24 13:04:48 lol Jun 24 13:04:54 THat seems very unlikely. Jun 24 13:05:07 Ibrahim did you even understood what you were doing? Jun 24 13:05:07 I am novice Jun 24 13:05:41 ibrahim perform nano /etc/apt/sources.list Jun 24 13:05:46 and tell us what you see Jun 24 13:06:01 if nano is not available try Jun 24 13:06:08 vi /etc/apt/sources.list Jun 24 13:06:17 it will open the file in an editor Jun 24 13:06:21 :) Jun 24 13:07:05 deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free; #deb-src http://ftp.us.debian.org/debian/ wheezy main contrib non-free Jun 24 13:07:57 OK, that should be fine. Jun 24 13:08:06 I found a forum thread about this issue. Jun 24 13:08:11 http://crunchbang.org/forums/viewtopic.php?id=39608 Jun 24 13:08:44 Ibrahim: 'sudo apt-get dist-upgrade' Jun 24 13:10:03 Actually, before you do that... Jun 24 13:10:23 'sudo apt-get install debian-keyring debian-archive-keyring' Jun 24 13:10:30 cool Jun 24 13:10:44 thanks a lot by the way Jun 24 13:10:45 you dont need debian-keyring Jun 24 13:11:05 This is better than other approaches because it does not install "debian-keyring", which is big and 99% of the time unnecessary. Jun 24 13:11:08 http://unix.stackexchange.com/questions/75807/no-public-key-available-on-apt-get-update Jun 24 13:11:10 see last post Jun 24 13:11:33 ... Jun 24 13:12:40 agmlego ...? Jun 24 13:12:48 you dont seem to be happy? Jun 24 13:13:09 debian-keyring is not that large. Jun 24 13:13:22 But really, debian-archive-keyring is the important one here. Jun 24 13:13:29 I think when I have written my message he has already executed the command ;) Jun 24 13:13:45 And far simpler than telling someone who had trouble looking up a config file how to manage keys with gpg... Jun 24 13:14:57 ^^ Jun 24 13:15:56 dpkg: error processing llvm-3.0-dev (--configure):.... when I run sudo apt-get install debian-archive-keyring Jun 24 13:17:25 Errors were encountered while processing: ntp binfmt-support llvm-3.0-runtime llvm-runtime llvm-3.0 llvm llvm-3.0-dev Jun 24 13:18:02 and also this before the error processing message .... any ideas please Jun 24 13:18:08 'sudo apt-get -f install' Jun 24 13:18:28 Or, you know, just reflash the thing and get back to stock. Jun 24 13:18:47 THe wonderful thing about embedded systems is the nuke-from-orbit approach is fast. Jun 24 13:21:02 I just run he command 'sudo apt-get -f install' Jun 24 13:21:18 still the same error as before .... Jun 24 13:21:34 do you mean that my BBB is broken ? Jun 24 13:21:43 Ibrahim: Please pastebin the entire contents of the error. Jun 24 13:22:01 YOu keep cutting off the full text, so none of us know what error you are actually seeing.

Jun 24 13:23:56 ok Jun 24 13:24:04 If you need to share large amounts of text, use http://pastebin.com Jun 24 13:24:08 And then share the link.

Jun 24 13:28:01 'sudo apt-get -f purge llvm' Jun 24 13:28:28 Then follow it by 'sudo apt-get autoremove' Jun 24 13:28:38 sudo apt-get remove llvm Jun 24 13:28:40 And maybe try reading the manpages for apt-get... ;-P Jun 24 13:29:01 sla89: I want to get to a clean system. purge is the correct option.
