**** BEGIN LOGGING AT Fri Mar 27 02:59:59 2015 Mar 27 03:01:21 hi . anyone have ft5x0x touchscreen drivers? Mar 27 03:12:17 anyone use touch LCD? not HDMI Mar 27 03:14:15 Nope, I do not use an embedded system for video. Mar 27 03:15:44 just i wanna know how to connet 7inch LCD Mar 27 03:17:28 Did you try the directions that either came with it, or are hosted by the manufacturer on their website, or are hosted on a community website like elinux.org? Mar 27 03:18:07 And if there are truly no directions in any of those places...why did you buy something you did not know how to use and did not come with any documentation to help? Mar 27 03:19:04 beagles are great at lots of stuff but if i was wanting video performance i would have probably grabbed another board which made that a priority Mar 27 03:21:10 i try with LCD CAPE Mar 27 03:21:25 just connect, and power on Mar 27 03:30:43 anyone use LCD CAPE?? Mar 27 03:32:02 OK, so, for starters, you should igve us some information. Mar 27 03:32:11 Like, a direct link to the product you bought. Mar 27 03:32:21 A list of terms you failed to get results for on Google. Mar 27 03:32:29 Ypour favorite soap flavor. Mar 27 03:32:39 What you have tried already to get it working. Mar 27 03:32:47 What symptoms it is exhibiting. Mar 27 03:32:59 Your least-favorite character on _Scrubs_. Mar 27 03:42:01 ^ Todd Mar 27 04:18:46 how to rotate touch LCD screen..? now BBB display by using HDMI. Mar 27 04:41:28 anyone know of any ribbon cables with male ends to connect to the headers of the bbb? Mar 27 04:43:28 nyt, .. ribbon cables don't have ends :) assemblies .. maybe .. you can make your own easily Mar 27 04:43:43 yeah its not for me Mar 27 04:43:50 wife is working on something and was just hoping to order some cables quick Mar 27 04:47:48 i wanna to use gdm commend to rotate touch LCD display, what packege shoud be installed? Mar 27 05:24:24 anyone use lcd cape? Mar 27 05:29:36 few Mar 27 05:33:10 how can i display it..? i`ve to change settings? Mar 27 06:35:08 ide like energia and arduino have a serial cable interface to load the sketches into them...so is there anyway we can load sketches from these ide, even via a usb cable ?? without using usb-serial cable... Mar 27 06:35:30 like for bbb Mar 27 06:38:42 maybe if you run an arduino emulator? Mar 27 06:42:19 tbr: this emulator runs without an OS ?? Mar 27 06:42:44 I don't think so Mar 27 06:42:55 :( Mar 27 06:43:28 so have to play with boot loaders ?? Mar 27 06:43:29 why would you try to dumb down a massively powered device? Mar 27 06:43:45 I mean, you could just get an arduino, if that's what you want Mar 27 06:45:16 yeah that can be done..but want to have arduino + processor.. Mar 27 06:45:58 since arduino doesn't have that high end processor.. Mar 27 06:48:10 you can attach your arduino to the BBB if that's what you want Mar 27 06:48:35 or you could use the PRU in the BBB instead, but that doesn't have a fancy shmancy IDE Mar 27 07:09:19 hello where can I download datasheet about my board Mar 27 07:09:30 anyone use LCD CAPE for bbb? Mar 27 09:15:58 For anyone interested in drones, check BeagleUAV crowdfunding campaign https://www.indiegogo.com/projects/beagleuav-linux-drones-with-the-beaglebone-black/x/7817776 ;) Mar 27 09:40:31 On my debian the ntp service is not booted after a reboot, when I run systemctl enable ntpdate.service I got back Failed to issue method call: No such file or directory. I installed it with apt-get install ntp ( on Arm BeagleBone ) Mar 27 09:45:55 I'd be surprised if it would be 'ntpdate' Mar 27 09:47:42 there's a timedatectl command with systemd that you can use to control ntp Mar 27 09:47:48 or is it datetimectl Mar 27 09:47:51 one or the other Mar 27 09:49:26 ok but what I want to achieve is that my time is synced when I reboot Mar 27 09:50:51 I'm pretty sure that the "enable ntp" setting is preserved across reboot Mar 27 09:52:31 anyway the command appears to be timedatectl set-ntp 1 Mar 27 09:56:33 NTP enabled: n/a Mar 27 09:56:34 NTP synchronized: no Mar 27 09:56:49 n/a huh Mar 27 09:58:09 well try systemctl enable ntp.service Mar 27 09:58:46 endrift: https://gist.github.com/DriesS/bc5a7b8a76ad7147fb16 Mar 27 09:58:57 still no ntp in ps -ef Mar 27 09:59:35 now do systemctl start ntp.service Mar 27 09:59:39 enable = do this next boot Mar 27 09:59:42 start = do this now Mar 27 09:59:48 you need to do both Mar 27 10:00:22 when I do systemctl start ntp.service no output Mar 27 10:00:32 that's normal Mar 27 10:00:35 and service not listed Mar 27 10:00:36 AxonetBE ypu need to configure ntp to ignore the drift, when you do not have a rtc or your start date is 1970 ntp might not sync the time Mar 27 10:00:37 in process list Mar 27 10:02:13 woglinde: ok thanks will try that Mar 27 10:05:17 in angstrom, i commended ts_calibrate to display 7inch touch lcd Mar 27 10:05:29 but i got error massage xres = 1024, yres = 768 tslib: Selected device is not a touchscreen (must support ABS and KEY event types) Mar 27 10:05:49 how can i solve this error? Mar 27 10:07:08 aaaaaaa_ use the calibration tool from the manufactor? Mar 27 10:09:00 woglinde_ i already did and got error in bbb linux Mar 27 10:18:27 aaaaaaa_ and now you think we can solve it? Mar 27 11:38:58 Ji Mar 27 11:39:01 hi Mar 27 11:39:10 Which tutorial is the best for installing cross compiler for bbb? Mar 27 11:39:54 FalconKnight depends on the system you want to run on the bbb Mar 27 11:42:52 For compiling this: https://github.com/jadonk/gsoc-application/tree/master/ExampleEntryJasonKridner Mar 27 11:48:44 Sorry, lost connection. So I need help to compile this: https://github.com/jadonk/gsoc-application/tree/master/ExampleEntryJasonKridner Mar 27 11:50:03 ???? Mar 27 11:50:18 so you want to participate in the GSOC right? Mar 27 11:50:29 How to install a cross compiler for this? I tried to follow a tutorial, but it was not working. Mar 27 11:50:53 ??? Mar 27 11:50:56 sorry Mar 27 11:51:09 thats one of the step to have to complete alone Mar 27 11:51:14 we don't do people's homework Mar 27 11:51:24 only one hint Mar 27 11:51:47 I just wanted a link to get started, not assistatiom Mar 27 11:51:58 *n Mar 27 11:52:28 hm google finds enough hints Mar 27 11:52:53 to get started you could just search how to install a crosso compiler on the distro you run. that's about all I'll say. Mar 27 11:52:56 only one hit on ubuntu it is fairly easy Mar 27 11:53:00 hint Mar 27 11:53:44 okay, thanks Mar 27 12:04:18 Humpelst1lzchen: I used your config and still do not get any usb device detected, have you used any usb device in your setup? Mar 27 12:06:12 Is anybody using any usb device on a BBB with kernel 3.14? I have tried with 2 different board (rev A5B and C) and none of them detect any USB device, I guess I am missing something on my kernel config Mar 27 12:12:35 jsolano, are they plugged in before you power on the BBB or hotplugged? Mar 27 12:26:48 good old musb :D Mar 27 12:51:26 hello Mar 27 12:51:58 i just want a user of beagle board to ask him some questions Mar 27 12:52:56 hello Mar 27 12:53:43 i want someone who's working with beagleboard to ask some questions Mar 27 12:54:23 http://www.catb.org/esr/faqs/smart-questions.html Mar 27 12:54:52 From IRC Topic: "never ask to ask, just ask" Mar 27 12:56:11 what you think will be the impact on the BeagleBoard.org community if a project like Beaglepilot is done? Mar 27 12:57:25 More equipment using BeagleBone for their autonomous XYZ's Mar 27 12:58:29 increasing number of users ... you mean that?! Mar 27 12:58:49 That will follow naturally - I don't know to what extend of course Mar 27 12:59:18 okk ... thank you :) Mar 27 12:59:36 how can i contact you Mar 27 13:01:08 Heh, write a message on this IRC channel - If I'm available, I will answer :) Mar 27 13:01:54 its friday Mar 27 13:02:59 its friday indeed :D Mar 27 13:03:28 so no wonder about some people Mar 27 13:03:33 and there question Mar 27 13:03:36 s Mar 27 13:07:17 it's not just any friday. it's gsoc application deadline friday. :D Mar 27 13:08:44 yes Mar 27 13:09:50 and the deadline is approaching :D Mar 27 13:10:05 let the game begin :D Mar 27 13:14:14 too late anyway Mar 27 13:24:51 while I got some proposals during the day, I previously spoke to the students and this was just the result of their preparation over the last week or two. Mar 27 13:25:10 the good stuff came in during the last few days from what I can tell Mar 27 13:49:25 hi Mar 27 13:50:40 hi Mar 27 13:54:59 tbr: as u proposed that we can use arduino+pru, so what 's the other benefit of the making arduino like libraries for starterware ?? Mar 27 13:55:12 hi Mar 27 13:55:37 geekswine: ah, this is some gsoc thing? Mar 27 13:55:48 yes Mar 27 13:55:58 can you help me?! Mar 27 13:56:32 yeah..jason asked me to enquire for these things ?? Mar 27 13:56:51 i want a non-GSoC mentor and a GSoc mentor Mar 27 13:57:03 geekswine: I have never worked with starterware and tbh am not sure what it would be useful for in general. Maybe at most to present the user with a familiar programming environment. Mar 27 13:57:28 Guest97018: there is a #beagle-gsoc channel or such for those questions Mar 27 13:57:29 sorry I want a non-Gsoc Mar 27 13:57:40 thanks Mar 27 13:59:40 hmm..if a user can buy a BBB then definitely he can buy an arduino too..i hope so.. Mar 27 14:02:35 geekswine: if the task is to port the arduino stuff to the BBB, then forget about having an arduino in addition to the board Mar 27 14:02:53 I thought you were trying to do something with the BBB running Linux. Mar 27 14:03:25 no no..just the porting stuff.. Mar 27 14:04:56 tbr wasnt there a beagle-gsoc channel? Mar 27 14:05:15 yes, there is, I'm not there though Mar 27 14:05:35 as I'm not on the beagle gang for gsoc, but am an org admin elsewhere Mar 27 14:05:48 aha Mar 27 14:06:28 tbr: which org ?? Mar 27 14:06:39 Xiph.org Mar 27 14:09:36 If the beaglepilot project is successfully completed, what will its impact be on the BeagleBoard.org community? Mar 27 14:10:12 * tbr would hope for a major milestone towards the establishment of OADS Mar 27 14:11:21 Hi Mar 27 14:13:27 I need some help with building the hello world project to ARM. Mar 27 14:14:05 I succesfully compiled it, but it is 8,4 Kbyte Mar 27 14:14:11 It sounds too small Mar 27 14:14:42 I used this tutorial: http://michaelhleonard.com/cross-compile-for-beaglebone-black/ Mar 27 14:15:07 Any ideas? Mar 27 14:15:27 lol eclipse Mar 27 14:16:01 first I did it form console Mar 27 14:16:12 the result was the same Mar 27 14:18:45 Can you give me any suggestions? Mar 27 14:22:34 hah, finally I got it Mar 27 14:22:36 FalconKnight: sounds like just abbout correct size for a simple hello world Mar 27 14:24:53 adj hm I think he will not succeed gsoc when he chooses beagle Mar 27 14:28:16 hello jkridner Mar 27 14:28:51 anyone know when rcn is back? Mar 27 15:03:52 howdy woglinde Mar 27 15:06:24 stt_michael: next week after ELC. Mar 27 15:07:33 jkridner, thought maybe so, thanks Mar 27 15:21:26 Hello, I would like to take some feedback here. Mar 27 15:21:29 howdy webglider.... Mar 27 15:21:36 webglider: what are you looking to do for GSoC? Mar 27 15:22:24 webglider: a short description that conveys the value you perceive would be best to try to encourage people here to give you feedback. Mar 27 15:23:41 I'm looking forward to building a simple desktop application which will make the job of setting up and updating the beagle board easier for newbies Mar 27 15:24:59 It will be a cross-platform application with an easy to use interface and will enable users to carry out operations such as updating to latest image without the need for downloading or installing any external toosl Mar 27 15:25:35 webglider #beagle-gsoc ? Mar 27 15:26:12 woglinde: yes this is the project I am proposing for this years GSoC Mar 27 15:26:16 woglinde: I'm trying to get some of the folks in #beagle-gsoc to reach outside just a bit to find out what people in the larger community want from #beagle-gsoc. Mar 27 15:29:40 woglinde: any thoughts on having a getting-started app? Mar 27 15:30:06 jkridner oh okay Mar 27 15:30:43 jkridner might be a good idea, beside I am personal like the shell more Mar 27 15:31:04 webglider which gui framework do you want to use? Mar 27 15:31:09 woglinde: but it is unlikely that a brand new user will be used to the shell Mar 27 15:31:18 and which porgramming language? Mar 27 15:31:34 woglinde might not like nw.js :-) Mar 27 15:31:50 woglinde: The idea is to use the NW.js framework to build a cross-platform application Mar 27 15:32:02 woglinde: so that would mean javascript :) Mar 27 15:32:07 which runs in the browser? Mar 27 15:32:10 * jkridner is about to go afk again Mar 27 15:32:41 jkridner, +5 for musb driver :D Mar 27 15:32:48 stt_michael he Mar 27 15:32:57 woglinde: no which runs on the desktop, nw.js is a technology which allows developers to build native desktop apps using javascript and node.js Mar 27 15:33:07 thats definitly not a gsoc topic Mar 27 15:33:15 currently, not unique to beagle, but +8 for brcm4330 fm radio driver Mar 27 15:33:38 * jkridner saw a really cool project with pru-dds last night. Mar 27 15:33:58 using PRUs to directly drive R-2R ladder to produced radio frequency signals. Mar 27 15:34:11 webglider uhm that means a new user hast to install all the node.js stuff which might be though and my clash on debian/ubuntu where node command is node nodejs Mar 27 15:34:18 may Mar 27 15:34:20 jkridner, .. where's your blog post about it :P Mar 27 15:34:46 haha -poof- Mar 27 15:34:48 webglider uhm that means a new user hast to install all the node.js stuff which might be though and may clash on debian/ubuntu where node command is node nodejs Mar 27 15:34:59 more typos Mar 27 15:35:34 woglinde: not necessary, it is possible to build and package standalone desktop applications using nw.js Mar 27 15:36:33 woglinde: after building the app, there are ways to package it separately for different platforms Mar 27 15:38:51 woglinde: there are a number of such apps which have already been built, you can have a look at: https://github.com/nwjs/nw.js/wiki/List-of-apps-and-companies-using-nw.js Mar 27 15:40:17 haha TopAnimeStream is semi legal Mar 27 15:47:12 are there any users here who had a hard time updating their boards to the latest image on their first try Mar 27 15:51:41 webglider hm some pop up but not many Mar 27 15:51:58 and most do not have a serial cable to tell us what was wrong Mar 27 16:25:25 hello everyone Mar 27 16:26:40 I need to stop bbb boot process at u-boot itself (I want to access u-boot prompt) . Mar 27 16:27:10 Can anyone please help me on this Mar 27 16:28:18 I have tried booting through External SD card and I have just placed u-boot.img & MLO file in hope that it would stop at u-boot Mar 27 16:29:27 Manish: m new but i think u can use uart to usb and can access u-boot prompt. Mar 27 16:30:10 Manish:have done using tx rx and got u-boot prompt. Mar 27 16:30:11 Manish: if you're connected to the serial console when you boot I think you get a chance to stop it at u-boot by pressing a key Mar 27 16:32:12 ketul : I have connected through UART to USB only but straight away it comes to kernel prompt Mar 27 16:34:05 ketul : could you please tell me how did you reach to u-boot ? Mar 27 16:34:31 Manish: let me send .img file Mar 27 16:34:54 ketul : Ok, Thank you Mar 27 16:37:08 alexanderhiam : Just wanted to know how it reached to kernel prompt when I only had MLO+u-boot.img in my External SD card Mar 27 16:39:05 ketul : Just waiting for .img file Mar 27 16:39:13 Manish: so you only have the USB cable plugged into the BBB? Mar 27 16:39:27 Manish:uploading Mar 27 16:45:20 manish_:got? although it is not having linux environment but you will get u-boot prompt Mar 27 16:45:53 ketul : Sorry I have got disconnected Mar 27 16:46:00 http://www.filefactory.com/file/5xom013opvet/bone_hello.exe-sdcard-ok.img.gz Mar 27 16:46:21 unzip and write using dd command Mar 27 16:48:13 ketul : Do I need only this file no MLO ? Mar 27 16:48:30 no it does everything. Mar 27 16:48:43 just extract and write using dd Mar 27 16:49:35 ketul : Thanks, I will try and let you know, Also I have connected through USB to USB as my machine dont have serial port Mar 27 16:50:47 manish_:keep in mind Mar 27 16:51:02 this wont work through usb. Mar 27 16:51:17 you have to use uart to usb communication Mar 27 16:51:45 manish_:you can refer http://www.armhf.com/wp-content/uploads/2013/06/ftdi_serial_debug.jpg Mar 27 16:55:16 ketul: Oh my bad , its UART(USB client on BBB) to USB(My machine side) Mar 27 16:56:33 we have "u-boot for arm", do we have categories for u-boot in this also ?? Mar 27 16:56:43 manish_:then it wont work. for that I dont have sufficient information Mar 27 16:59:02 Ketul : Just wanted to get correct picture on how I connected, The diagram you sent is exactly how I connected in my set up Mar 27 16:59:20 hello, I want to built a framework which will enable users to program pru using high-level languages. Can I have comments on how it will impact the community ? Mar 27 17:00:22 manish_: if you only have a usb cable, then you won't get access to uboot Mar 27 17:00:52 manish_: you'd need a UART adapter (e.g. a "ftdi cable") and make sure it's 3.3V Mar 27 17:01:09 Hey. Can somebody please give me a brief feeedback for beaglebone Gsoc project. Just a few lines as to how it will impact the community. Mar 27 17:01:18 sidbh: hello, I want to built a framework which will enable users to program pru using high-level languages. Can I have comments on how it will impact the community ? Mar 27 17:01:40 tbr : It would be great if you could point out some diagram for the same. Mar 27 17:02:04 manish_: the SRM mentions the debug port Mar 27 17:05:12 tbr: could please take out a moment and comment on this. would be really helpful . https://docs.google.com/a/itbhu.ac.in/document/d/1OmQnWQ13XTvoSWPhJR5XT-VxP6fhwDHPNU51fH45Xg8/edit?usp=sharing Mar 27 17:06:32 shubhangi: my comment is "permission denied" Mar 27 17:07:35 tbr : you can edit the doc straight away. Mar 27 17:07:48 i gave can edit permissions Mar 27 17:08:29 try now Mar 27 17:10:10 shubhangi: have you worked on the linux kernel before? Mar 27 17:10:50 i made this https://github.com/shubhi1407/LEDtoggle Mar 27 17:11:04 a simple driver to access pru. Mar 27 17:11:54 good luck, looks like quite a task Mar 27 17:11:57 i can send you the entire proposal if you have time. sent you just the abstract so that it doesnt take much of your time Mar 27 17:12:22 tbr : thanks. i need a comment though :) Mar 27 17:12:33 proposal requirements Mar 27 17:13:05 I don't have PRU experience, so it's hard to comment Mar 27 17:14:07 okay. thanks for the time :) Mar 27 17:14:34 tbr: do you know someone on this channel who has ? Mar 27 17:15:28 #beagle-gsoc Mar 27 17:16:14 #beagle-gsoc has requested me to get a feedback from here Mar 27 17:16:34 mentors there have already commented Mar 27 17:17:11 Are there any GSoC mentors?! Mar 27 17:17:28 on #beagle-gsoc yes Mar 27 17:45:10 any one with pru experience online ? please comment on this proposal https://docs.google.com/document/d/1OmQnWQ13XTvoSWPhJR5XT-VxP6fhwDHPNU51fH45Xg8/edit?usp=sharing Mar 27 17:48:36 jo panto Mar 27 17:48:41 Hello !! can anyone give me any feedback or comment on developing high-level language support for pru ? Mar 27 17:48:49 hi Mar 27 17:49:07 kiran4399, you have 4K words of instruction space Mar 27 17:49:18 think about it Mar 27 17:49:27 hi woglinde Mar 27 17:49:46 panto fine you are helping the gsoc folks Mar 27 17:50:19 woglinde, my time is limited but I'll try to help if I can Mar 27 17:51:03 panto: Actually .. I need some feedback on how pruduino (framework for developing high-level language support for pru) will impact the community.. I've got to put that on my proposal.. Can you please give your comment on this ? Mar 27 17:51:43 kiran4399, not today Mar 27 17:51:59 visiting CA clients so -ENOTIME Mar 27 17:52:17 panto: I've 1:15 hrs for the deadline .... :-( Mar 27 17:52:32 ok, feedback... Mar 27 17:52:33 But that's OK !! Mar 27 17:52:42 only run the time critical stuff on the PRU Mar 27 17:52:52 initialization, debugging etc, all go to ARM Mar 27 17:53:20 panto : just a few lines of feedback here too. would be grateful https://docs.google.com/document/d/1OmQnWQ13XTvoSWPhJR5XT-VxP6fhwDHPNU51fH45Xg8/edit?usp=sharing Mar 27 17:54:10 panto: the high-level picture is like is.. the node.js interpreter will generate a pruspeak script and that script will be loaded to the pruspeak interpreter.. Mar 27 17:54:50 as I said Mar 27 17:55:06 you only have 4K instruction space for PRU Mar 27 17:55:16 this ain't a general purpose part Mar 27 17:55:21 you have to be smart about it Mar 27 17:55:42 kiran4399: prehaps establishing a good heuristic for determining what goes into the PRUSS and what doesn't. Mar 27 17:55:58 Examples - things that slam the L4 probally doesn't need to be in the PRUSS Mar 27 17:58:31 panto: OK !! So are you saying that there is a limit to the source code for the pruspeak interpreter ??? Mar 27 17:59:09 no, I mean there's a limit to the instruction space and data space of each PRU Mar 27 17:59:18 what is your strategy/heuristic to deal with it Mar 27 17:59:42 how much space does your interpreter uses per statement (average) Mar 27 17:59:43 etc Mar 27 18:00:29 "too much" ;) Mar 27 18:00:56 panto: when you leaving CA? Mar 27 18:01:13 ds2, tomorrow Mar 27 18:01:23 wow tight schedule Mar 27 18:01:31 yeah :( Mar 27 18:01:33 panto: My job is to write the object-handlers in a node.js library which when invoked by the js program .. ...will build a pruspeak script... This pruspeak script will simply be fed to the pruspeak interpreter which karki has made.. Mar 27 18:02:12 panto : sorry, but i desperately need a feedback. just a small comment Mar 27 18:02:30 I desperately need a time machine and/or cloning Mar 27 18:02:41 :) Mar 27 18:04:00 panto: I am not building an interpreter as such..what is your opinion on this idea ?? Mar 27 18:05:50 too bad you can't wait 11 weeks for a GSoC TARDIS project :D Mar 27 18:06:25 ds2: what is TARDIS ?? Mar 27 18:22:41 Hi all, I'd like to request feedback from the community on a GSoC proposal I'm writing Mar 27 18:23:48 Namely what do you think would the impact of the project be on the beaglebone community Mar 27 18:24:29 The name of the project is Enabling accurate magnetic field measurements on Cubesats using the BeagleBoard platform Mar 27 18:24:40 Abstract: Magnetic field measurements play an important role in Earth-orbiting satellites, such as attitude determination and scientific instrument pointing. Unless built specifically for high accuracy measurements, satellites usually come with significant magnetic sources of errors that severely degrade measurement accuracy. This GSoC project aims to implement algorithms that enable low-cost high quality ma Mar 27 18:24:46 gnetic field measurements on smaller spacecraft without booms using the BeagleBone platform. Mar 27 18:26:29 For anybody interested in the details it lives here: https://www.google-melange.com/gsoc/proposal/review/student/google/gsoc2015/niko_visnjic/5629499534213120?validated=True Mar 27 18:26:40 should be publicly accesible Mar 27 18:42:50 ketul : I flashed the image given by you but board is not booting with that image Mar 27 18:48:11 manish_:how do you know? Mar 27 18:48:48 it won't blink the leds. but u will get output on serial console if connected Mar 27 18:50:24 manish_:and you will get u-boot prompt too. :) Mar 27 18:53:04 ketul : I am unable to open minicom prompt Mar 27 18:53:45 I would recommend you to use picom Mar 27 18:53:47 ketul : I dont have serial on my machine , using USB Mar 27 18:54:12 yeah. but on bbb u have serial right? Mar 27 18:54:38 manih_: you can alo try putty Mar 27 18:54:50 alo* Mar 27 18:55:32 also* Mar 27 18:55:59 manish_: picocom -b 115200 /dev/ttyUSB0 Mar 27 18:56:20 ketul : yes connected with that only , I will try with picom Mar 27 18:56:51 use the given command Mar 27 18:56:54 manish_: Mar 27 18:57:56 ketul : Ok Mar 27 18:58:09 manish_:(y) Mar 27 18:59:48 ketul : In my case its /dev/ttyACM0 Mar 27 19:00:12 no it wont work on bb usb as I told u earlier Mar 27 19:00:19 manish_: Mar 27 19:01:30 ketul : BBB side I have not connected to USB, its USB client near to Ethernet port Mar 27 19:02:22 manish_:it should be uart on bb side as told u earlier. it wont work on bb's usb Mar 27 19:02:41 you need to have ftdi to usb Mar 27 19:04:37 https://www.sparkfun.com/products/9717 manish_ Mar 27 19:05:21 ketul : yes its UART on BBB side, when i put only u-boot & MLO file then how its getting kernel ? Mar 27 19:05:54 did you try with ACM0? Mar 27 19:06:36 ketul : yes I tried , till now using that terminal only Mar 27 19:07:58 got u-boot? Mar 27 19:08:04 prompt manish_ Mar 27 19:09:41 ketul : No this is also not working , Its not booting Mar 27 19:10:36 I tried with this image and booted just a week ago. Mar 27 19:10:40 manish_: Mar 27 19:10:52 I think there would be USB0 port Mar 27 19:12:28 ketul : Ohh Can you please tell me how many files do you have in SD card ? Mar 27 19:13:18 4 Mar 27 19:13:21 macbook-uxs: Mar 27 19:13:27 sry Mar 27 19:13:29 manish_: Mar 27 19:15:10 manish_:how many do u have? Mar 27 19:16:11 ketul : I tried /dev/tty0 and getting terminal ready and some junk values are coming .. No idea is that BBB terminal or not Mar 27 19:16:23 ketul : I have 4 files only Mar 27 19:17:28 tty0 is not for external devices manish_ Mar 27 19:17:58 ketul : Ok Mar 27 19:18:58 so you would be getting usb0 otherwise I dont think so it work. Try to connect ony ftdi to usb to pc and see ls /dev/.. If you are getting usb0 or not? Mar 27 19:19:00 manish_: Mar 27 19:24:29 ketul : ftdi is another option but if same images are working for you Mar 27 20:46:11 I noticed with RCN's ubuntu Image there is two kernels. vmlinuz-3.14.33-ti-r50 vmlinuz-3.19.0-armv7-x3. New with uboot how can I tell it to boot the vmlinuz-3.19.0-armv7-x3 kernel? I am currently running Linux adhorden-beaglebone-black 3.14.33-ti-r50 #1 SMP PREEMPT Thu Feb 12 03:52:59 UTC 2015 armv7l armv7l armv7l GNU/Linux. Mar 27 20:55:15 What's the stock situation on things other than Bone? Mar 27 21:42:45 ronaldlees: Such as? Mar 28 00:08:10 how to put a Debian desktop on my BeagleBone Black, screen is black. Mar 28 00:16:06 get a flasher that is not console only Mar 28 00:16:38 or apt-get install your xserver of choice Mar 28 01:05:46 so the bbb has 14 PWM, if we need more is there a way to setup the other GPIO to act as PWMs? Mar 28 01:11:18 depending on the frequency you use, I'd imagine you could fake it with the PRUs Mar 28 01:11:51 i'll look into it, thanks endrift Mar 28 01:35:57 yeowza: do you need video output? otherwise I suspect you can abuse the lcdc to generate 24 pwm channels Mar 28 01:36:53 hmm, might not be able to reach 100% duty cycle though, I think then are some mandatory gaps Mar 28 01:37:12 you can get both if you push your luck Mar 28 01:37:59 ? Mar 28 01:38:34 16 bit LCD Mar 28 01:38:49 well, not 24 pwm but 16bit LCD + 8 PWM Mar 28 01:39:05 hmm, that would impose even more serious constraints though Mar 28 01:39:22 on sw or hw? Mar 28 01:39:30 on signal timing Mar 28 01:39:43 there is that, yes Mar 28 01:40:04 many, not all, LCDs are surprisingly tolerant of their timing so it isn't that bad Mar 28 01:45:27 yeah, but for pwm I'd configure the screen height to 1 line Mar 28 01:45:45 or not, crap, vsync is in full lines Mar 28 01:46:03 and 2048 columns? Mar 28 01:46:21 what's the need for that many PWM's? Mar 28 01:46:31 crap that, I'd make it minimum width probably... not sure yet Mar 28 01:46:32 no idea Mar 28 01:46:35 ask yeowza :P Mar 28 01:46:49 min width? how's that PWM? Mar 28 01:49:00 min width and high enough to get enough resolution in duty cycle, frame rate = pwm frequency Mar 28 01:49:33 oh in that sense thought you meant min width the hw supports Mar 28 01:50:16 ohh, I just came up with a sleazy way to solve the vsync problem, I think 1 line may still be workable (if duty cycle configurable in steps of 1/4096 suffices) Mar 28 01:50:38 you want to limit the range of the PWM? Mar 28 01:51:08 with 1 line, half the time would be the vsync period, during which you can't send new data Mar 28 01:51:25 but it does hold the last data Mar 28 01:53:43 so you can have the vsync period high for values > 50% and low for < 50%, and use the 2048 line pixels to set the duty cycle within those ranges Mar 28 01:54:13 it would mean a 180 degree phase change around 50% duty cycle, but that may not be a problem depending on application Mar 28 01:54:28 depending on fast... a GPIO might be simplest Mar 28 01:54:47 gpio would be guaranteed messy Mar 28 01:55:07 donno about that Mar 28 01:56:02 pru gpio would make more sense (if you run out of timer/eCAP/ePWM pins) Mar 28 02:11:48 yeowza: "so the bbb has 14 PWM" -> you're including eCAP 1 in that count? note that it's not available on the cape headers (though you can still get at it if you really want, e.g. it's on the serial header) Mar 28 02:12:11 i just got bblack Mar 28 02:12:22 or A beagle bone black Mar 28 02:12:34 and I can ssh into the box Mar 28 02:12:47 how ever i cant ping out of the box Mar 28 02:13:26 zmatt: I wasn't very thorough in counting, thanks for the input, I am building a robot Mar 28 02:19:37 it's a shame the lcdc requires >= 1 pixel of hsync per line and >= 1 line of vsync per frame, otherwise it could have made an excellent general-purpose parallel output player, especially for periodic signals Mar 28 02:41:43 zmatt: the design is open, you could fix that oversight and order up a board to your specs right Mar 28 02:42:51 wmat: ehh, I'm talking about a constraint that the LCDC peripheral of the AM335x imposes Mar 28 02:43:11 that's a little hard to fix :P Mar 28 02:46:14 oh, sorry, if it's a constraint of the cpu, so be it Mar 28 02:48:11 yeah, it may still be interesting for applications where that constraint isn't a big problem (e.g. if you'd want 24 serial outputs... no idea why, but who knows) but for pwm it's a bit annoying Mar 28 02:50:28 zmatt: do any boards out there meet those requirements? Mar 28 02:50:48 ? what does the board have to do with anything? Mar 28 02:51:50 ok, what does meet those requirements then? Mar 28 02:52:04 eh, every *intended* application of the lcdc? namely video Mar 28 02:54:12 i'm a console only guy, so i don't get it. Mar 28 02:58:06 the point is that you can fully control the data during the "active video" part, but there are also mandatory hsync and vsync periods to structure the datastream into lines and frames, and the lcdc doesn't let you affect the data output during this periods (it holds the values of the most recent pixel) Mar 28 02:58:29 if you want to (ab)use the lcdc to output a continuous stream of parallel data, that's a problem **** ENDING LOGGING AT Sat Mar 28 02:59:58 2015
