**** BEGIN LOGGING AT Thu Apr 27 03:00:00 2017 Apr 27 03:34:10 * jkridner is finally updating https://beagleboard.org/getting-started Apr 27 03:34:26 I'm currently editing Step #1: http://jadonk.github.io/beaglebone-getting-started/START.htm#step1 Apr 27 03:34:39 that github.io page contains my work-in-progress. Apr 27 03:34:42 comments welcome. Apr 27 03:36:37 planning to remove step #2 with "Enable a network connection" Apr 27 03:55:26 yay for a getting-started Apr 27 03:57:12 remove? replace you mean? Apr 27 04:00:17 maybe also consider inserting an optional step to reflash it with the latest firmware... you never know how long that "new" board they got has been lying on a shelf somewhere, it might be running something really ancient Apr 27 04:08:17 zmatt: yeah, replace. Apr 27 04:08:54 zmatt: do you think the comment about "If any steps fail, it is recommended to update to the latest software image to use the instructions below." isn't strong enough? Apr 27 04:45:31 ah, sorry, I had overlooked that Apr 27 04:46:39 possibly the visual style might have contributed to that though Apr 27 04:48:54 and it might be useful to move it closer to where the "action" starts, I can imagine the impatient might quickly gloss over "power and boot yada yada..." Apr 27 04:49:10 :) Apr 27 05:07:20 Hi, I am having some issue with my beaglebone. After installing nodejs7, the web site can no longer see the device connected to my computer. The 192.168.7.2 does not work either. Apr 27 05:08:42 I can still used putty to ssh in the device but I get input/output error report. how can i fix that? Apr 27 05:14:36 welcome to nodejs, any time you upgrade everything breaks :) Apr 27 05:16:18 at the very least you'll need to recompile all extension modules used (and then hope they still compile) Apr 27 05:22:04 compile? just put in an emulator to match the old version :D Apr 27 05:23:25 Hi Apr 27 05:23:35 Where can I buy edumip motors ? Apr 27 06:58:50 . Apr 27 09:00:03 hi Apr 27 09:01:08 i am new to beaglebone black.... i want to implement lora to lora communication using this mcu. Is there any reference or sample code available for this project Apr 27 09:03:22 hi Apr 27 09:04:24 calling the BBB a "MCU" is like calling a cruise ship a "boat" Apr 27 09:04:27 i want to implement lora to lora (sx1272) communication using this MCU BBB. Plz someone guide me how to implement this Apr 27 09:04:56 it does have MCU like cores, the PRUs, though Apr 27 09:05:57 rohit__: step #1: learn electronics Apr 27 09:05:57 presently i am using BBB as MCU only Apr 27 09:06:04 rohit__: step #2: learn programming Apr 27 09:06:13 rohit__: step #3: learn embedded linux Apr 27 09:06:20 rohit__: step #4: ... Apr 27 09:06:26 rohit__: step #5: profit Apr 27 09:09:41 there are only a few people who bother with bare metal programming of the BBB Apr 27 09:09:51 @Attila Kinali i have already implemented LORA to LORA communication using Arduino, MSP430 and also LORAWAN using NODEMCU. So i think i have enough knowledge to implement this. I asked suggestion related with this project not for my knowledge. Apr 27 09:09:57 most just go for linux and if they need real time things, then PRU Apr 27 09:10:10 rohit__: then start at step #3 Apr 27 09:10:27 why can't we bother about bare metal..... Apr 27 09:10:37 tbr: the chip in question has a simple spi interface Apr 27 09:10:45 tbr: no need for real timey things Apr 27 09:10:58 rohit__: because life is too short Apr 27 09:11:37 Its your thought dude not everyone Apr 27 09:12:30 rohit__: well, if you dont want our advice, that's fine Apr 27 09:12:42 rohit__: but please remember, that _you_ asked for advice Apr 27 09:13:02 i asked advice related with this project Apr 27 09:13:31 tbr: what i really wonder is, why semtech choose to do chirped FSK instead of a DSSS system. it would give much higher processing gain at the same BW usage with about the same complexity Apr 27 09:15:00 tbr: maybe signal synchronization was too complex for them... Apr 27 09:15:11 rohit__: you asked for advice, we gave advice Apr 27 09:15:45 rohit__: doing bare metal on a complex SoC like the omap family is going to costs you months if not years to do it correctly Apr 27 09:16:07 rohit__: if you are willing to do that, fine... everyone else will use linux instead and be done in days or weeks Apr 27 09:19:42 @koth you mean to say for such communication i should go with other module instead of BBB.... Apr 27 09:19:55 that really depends on what you are doing Apr 27 09:20:06 you have not told us anything about the problem you are trying to solve Apr 27 09:22:48 i told clearly that i want to implement node to node communication using this BBB and sx1272. But i am unable to find any reference or sample example related with semtech. If it is available plz provide me that link this what i want. Apr 27 09:24:01 so you want to specifically use the BBB and sx1272? Apr 27 09:24:08 yes Apr 27 09:25:41 because node to node communication and lorawan gateway i have already implemented using arduino and NODEmcu LUA....... but now i want specifically to use BBB and sx1272 Apr 27 09:26:07 then what i would do is: 1) read the sx1272 datasheet, it describes how to interface it, 2) read how to do spi on linux 3) have a look at the relevant sections of the TRM and the schematics of the BBB, 4) get coding Apr 27 09:26:09 just node to node simple lora communication Apr 27 09:26:50 if you are quick on your feet, you should be done within a week Apr 27 09:27:14 if you reuse code from your arduino projects, you will be even faster Apr 27 09:30:10 yeah i have done node to node communication also in linux platform using raspberrypi. Problem which i am facing is like this: - Compiling arduPi... In file included from arduPi.cpp:23:0: arduPi.h:48:21: fatal error: bcm2835.h: No such file or directory compilation terminated. Compiling arduPiUART... In file included from arduPiMultiprotocol.h:18:0, from arduPiClasses.h:31, from arduPiUtils.h:39, Apr 27 09:31:01 do you understand what the error message is saying? Apr 27 09:31:26 oh sorry wait Apr 27 09:31:39 g++: error: /home/root/cooking/libraries/arduPiLoRa/arduPiLoRa.o: No such file or directory Apr 27 09:32:02 g++: error: /home/root/cooking/arduPi-api/arduPiUART.o: No such file or directory Apr 27 09:33:04 its shows error for object file. Is BBB require file file for compilation...... Apr 27 09:33:27 do you understand how to compiler error messages? Apr 27 09:33:49 NO Apr 27 09:34:48 if i knew this then i would solved it previously. Apr 27 09:35:05 well.. then why dont you ask about this in the first place? Apr 27 09:35:31 what you need is to get a book on programming on unix/linux Apr 27 09:35:37 there are plenty of those Apr 27 09:35:40 get one of them Apr 27 09:35:42 read it Apr 27 09:37:13 thanks alot for you advice but i think if i compile my .c file with gcc -c then i would able to create object file. Apr 27 09:38:38 but the thing is i have lots of c file and h file which have to compile at same time for that i have to create 1 makefile to show them path.... Apr 27 09:42:05 if i able to find solution on programming on unix/linux then why this chat group is created just to advice to read book.. if don't know the solution better tell in the first place. every time dnt say read book read book... thanks and bye. The problem is not with the path....... Apr 27 09:42:08 leave Apr 27 09:43:38 reisende soll man nicht aufhalten Apr 27 09:43:43 ja Apr 27 09:58:38 tjoar. Apr 27 10:03:42 kids Apr 27 11:20:47 my beaglebone will not connect to cloud9. does anyone knows what might cause that? Apr 27 12:20:14 Abgie: what does "will not connect" mean? Apr 27 12:20:20 Abgie: do you get an ip? Apr 27 12:20:25 Abgie: can you ping the BBB? Apr 27 12:20:37 Abgie: does your browser return an error message? if so, which one? Apr 27 12:21:13 Abgie: will you send me some high grade swiss chocolate? Apr 27 13:14:07 yes I can ping the beaglebone and ssh into it using putty but the browser does not see the device connection. So I cannot program the device from cloud9. Apr 27 17:22:05 anyone joining the webinar in 39 minutes? Apr 27 17:22:15 any questions I should be prepared to answer? Apr 27 17:24:21 which webinar would that be? Apr 27 17:29:00 https://www.facebook.com/events/106559623239661/ Apr 27 17:29:05 ugh, facebook Apr 27 17:29:42 https://events-na1.adobeconnect.com/content/connect/c1/2186806689/en/events/event/shared/2263216804/event_registration.html?sco-id=2297620450&_charset_=utf-8 Apr 27 17:32:44 thanks Apr 27 19:06:26 anybody here attend? Apr 27 19:06:32 thought it went OK. Apr 27 19:06:46 didn't get to share much of /sys :-) Apr 27 19:07:37 I went along for the ride Apr 27 20:23:56 does anyone in here speak german? Apr 27 20:25:17 meh nvm Apr 27 21:21:50 hey folks ... i need to flash a beagle blck back to factory ... can i use a 64gb sandisk Microsdxc or do i need a smaller card ? Apr 27 21:32:16 ghostD0g: larger cards are never a problem Apr 27 21:32:22 I think Apr 27 21:32:27 hmm Apr 27 21:32:44 not sure actually now that I think of it Apr 27 21:32:45 my problem is the only other card i have is a 2gb Apr 27 21:33:19 i looked around in town and have a hard time finding smaller cards Apr 27 21:33:47 I'm assuming you've tried the 64GB card? Apr 27 21:33:54 so i bought a 64gb .. but is i open it i cant take it back Apr 27 21:34:23 I think sdxc should simply work Apr 27 21:34:46 i am trying to get confirmation before i open the package Apr 27 21:34:58 "The SD driver is capable of handling SDXC cards since the commands and state machine are compatible with that of SDHC cards." Apr 27 21:35:05 i think so too as the bbb was made after 2010 Apr 27 21:35:18 so anything that supports SDHC also supports SDXC Apr 27 21:35:45 (i.e. there really wasn't a good reason for the name change) Apr 27 21:36:09 hmm Apr 27 21:36:47 well i did buy it from costco ... if it doesnt work ... i bet they will take it back Apr 27 21:38:17 i am also trying to find what the factory image should be .. i am new to bbb... is it just angstrom? Apr 27 21:38:38 or debian Apr 27 21:39:04 well, technically what the "factory image" was depends on when and where your bbb was produced ;) I strongly suggest one of the latest debian images however instead of whatever used to be on your bbb Apr 27 21:39:10 angstrom hasn't been the default for ages now Apr 27 21:40:23 its marked element 14 .. kk debian it will be Apr 27 21:40:30 :) Apr 27 21:40:34 thank you Apr 27 22:15:19 how to tell what revision my bbb is ? Apr 27 22:19:02 pcb is marked rev B6 processor is AM3358BZCZ100 ... i am assuming rev B ? Apr 27 22:37:30 ghostD0g: rev C if eMMC size is 4GB Apr 27 22:58:15 BBBW is based on rev C, one would assume, right? Apr 27 22:58:22 I just got a couple the other day Apr 27 23:02:42 the BBBW is a completely different pcb Apr 27 23:44:25 I figured, I just have been setting my hostnames based on distribution and revision, e.g. blah-debian-c where c is the rev. For lack of a rev I've named the wireless ones *-wi Apr 28 00:24:13 we just use first names (paul, alex, etc) for beagles used for development or experimental purposes Apr 28 00:24:32 more convenient and memorable than numbers Apr 28 00:29:37 Well they're my pets, I can't give them people names :3 Apr 28 00:29:54 I name them mainly based on the color of the enclosure they're in though, + distro + rev Apr 28 00:30:15 azul-debian-c, for example Apr 28 00:46:36 anyone selling boards? Apr 28 01:00:02 what kind of boards? Apr 28 01:02:04 linux board Apr 28 01:02:14 with usb port, preferably with wifi Apr 28 01:07:11 hi ayjay_t **** ENDING LOGGING AT Fri Apr 28 03:00:01 2017
