**** BEGIN LOGGING AT Mon Apr 23 03:00:12 2018 Apr 23 09:54:43 how to mount the emmc of the BBB when booting from SD? Apr 23 09:56:05 i have a M62704: rootfs "mountpoint", but i don't know how to use it Apr 23 12:37:25 parduz: what do you mean with "M62704: rootfs "mountpoint"" Apr 23 12:37:26 ? Apr 23 12:38:59 a mountpoint is a path where a filesystem is mounted, so whatever you mean by "M62704: rootfs", is it obviously not a mountpoint Apr 23 12:39:57 you can mount the emmc with e.g. sudo mount /dev/mmcblk1p1 /mnt/tmp where /mnt/tmp is the mountpoint (needs to be an existing empty directory) Apr 23 13:23:52 Hi zmatt. I mean that in the BBB file explorer there's a thing with a chip icon named that way, which in the properties says is a mountpoint Apr 23 13:25:02 anyway, i mounted it in the same way you told me, by looking with Fdisk at the partitions. Apr 23 13:50:02 oh, you're using a desktop environment on the BBB Apr 23 13:52:11 I'm still not sure what the thing you're describing is... I hope it's not messing directly with the block device while you've got the filesystem mounted (I hope the device's permissions wouldn't let it anyhow) Apr 23 15:33:10 Hello Apr 23 15:33:38 I have few queries Apr 23 15:36:21 thanks for sharing that Apr 23 15:40:58 lol Apr 23 16:33:59 I'll never understand people coming into a chat room to ask if they can ask questions, instead of just asking Apr 23 16:35:24 TonyTheLion: If you're not used to chat rooms, it seems like common courtesy. In real life, asking to ask is done all the time. So I can totally understand it, even though it is completely annoying :-p Apr 23 16:35:55 perhaps Apr 23 16:53:58 yeah, bbb.io/chat needs a few guidelines in large font at the top, not links to long documents noone is going to read Apr 23 17:14:05 though indeed... going into a large hall with a few hundred people who are either sleeping or doing something else, yelling your question for all to hear, and then sitting down to relax in a chair yourself... is not recommended in real life Apr 23 18:13:21 the internet is not real life Apr 23 19:32:10 I'm have ZERO luck adding nodes to node-red. Can anyone tell me how. I've tried all sorts of things already. Apr 23 19:35:31 I have tried 4 different distros of Debian 9.x and from the Debian loging and as root. I tried both npm and the install within node-red palette manager. Nothing is working for me. Apr 23 19:36:15 The node-red that is packaged in the beagleboad web site includes node-red and that part work. Apr 23 19:37:19 I just can't add any nodes -- which makes it worthless to me for my app. I suppose I's doing something wrong but I just can't figure it out. Apr 23 19:39:02 Alice: no errors to go on? (either in the user interface or in logs) Apr 23 19:39:29 plenty errors, should I paste here? Apr 23 19:39:36 use pastebin.com or similar site Apr 23 19:40:29 Ok I'll post them, but I gotta go now, I'll try after lunch. Thanks. Apr 23 19:40:56 I never used IRC or pastbin (I'll have to figure those out first) Apr 23 19:57:50 I looking to purchase Model Rev A5 but it has a input voltage level of 5V and the sensor that I am looking to monitor is giving me 24V and I would like to know if this voltage is safe for the processor. Apr 23 20:37:31 NCAT: model rev A5 of what? Apr 23 20:37:54 24V is not safe for any processor I've ever seen of any manufacturer Apr 23 20:39:33 for the beaglebone, 3.3V is the limit for digital I/O and 1.8V for analog inputs Apr 23 21:43:07 hey guys, noob question about handling multiple input.. I was looking at the push button tutorial, which is all well and good, but i was curious if there was a pattern for scaling that Apr 23 21:43:36 jrich__: your question is really unclear Apr 23 21:43:39 like i assume i dont want a "check" fucntion for every button... i want one that scans all the buttons, and updates the state for each Apr 23 21:43:45 im working to clear it up, sorry :-/ Apr 23 21:43:58 what tutorial are you referencing? Apr 23 21:44:28 and generally you don't want to poll buttons at all, you can get events on gpio changes instead Apr 23 21:44:30 http://beagleboard.org/Support/BoneScript/pushbutton Apr 23 21:44:40 setInterval(check,100) Apr 23 21:44:53 okay, yeah that's just meant as a stupid-simple example Apr 23 21:45:07 so that checks the one button state and moves on... im going to have a bunch of sensors that act like push buttons (water sensors) Apr 23 21:45:15 http://beagleboard.org/Support/BoneScript/attachInterrupt/ Apr 23 21:45:30 sweet i'll go read up on that Apr 23 21:47:50 hmm, a bit unclear what the purpose of the handler argument is Apr 23 21:48:18 also, ew for the use of eval Apr 23 21:50:57 uhh what Apr 23 21:51:01 that example looks wrong Apr 23 21:51:40 I'm reading the source code of the attachInterrupt function... it looks really weird to me Apr 23 21:53:04 also wtf they're creating a new epoll instance for each gpio on which an interrupt is attached Apr 23 21:58:54 this code is so... weird.... Apr 23 22:08:25 Hello! I am new to this community and I am trying to make a mobile robot but I need to power my Beaglebone Enhanced, 4 servos, Camera, microphone and also some pressure sensors all at the same time. Is there any portable battery option that can support these? Apr 23 22:09:00 Thanks for you incoming Answers~. Apr 23 22:21:42 ah the nodejs epoll package actually shares a single epoll instance Apr 23 22:29:05 Hello, I am a beginner in the field of Beagle bone based projects, and I need a power supply for a mobile robot project that I am eyeing. I need to power a Beagle bone black, 4 servos, 1 Camera, microphone, speakers and an air pump. My only option is Battery as I have to make the robot move a lot. So can anyone please help me with this decision of battery? I am thinking of using a mobile portable battery of capaciity Apr 23 22:29:06 10,000 mAH, with o/p parameters as 5V DC 6300 mAH. is it safe? Thanks a ton! Apr 23 22:30:49 I don't understand why you're asking this here. your question has nothing to do with the beaglebone Apr 23 22:42:42 n7fenrir[m]: Might try ##electronics Apr 24 01:02:31 How do I post a .jpg image here (it shows errors when I try adding node to node-red) ? Apr 24 01:21:32 uhh, can't you just copy-paste the error message to a paste site like pastebin.com ? Apr 24 01:23:04 if you want to share an image you'll need to use some image hosting service, but text format is strongly preferred over a screenshot Apr 24 01:24:45 ok, I can paste text here ? Is that ok ? Apr 24 01:24:57 no. Apr 24 01:25:09 ok, where/how for text ? Apr 24 01:25:17 again (third time), use a paste site like pastebin.com Apr 24 01:25:46 ok, I guess I gotta go register for that (back soon) Apr 24 01:25:48 nope Apr 24 01:25:50 no need to register Apr 24 01:25:59 you can just paste your text there and click the button Apr 24 01:27:34 ok, I did it. After pasting I clicked the [+ New Paste] button. Can you see it ? Apr 24 01:29:00 I'm not omniscient no. it will help if you give the link here Apr 24 01:29:48 you are not? it sure seems like you are Apr 24 01:30:02 well hecky darn its at https://pastebin.com/ Apr 24 01:30:12 -.- Apr 24 01:30:43 you didn't click the "Create New Paste" button Apr 24 01:31:11 I'm not sure what button you did click, but evidently not one that does something Apr 24 01:32:26 sorry, this is all new to me, I hope its ok now Apr 24 01:32:32 https://pastebin.com/SOMEUNIQIDENTIFIER Apr 24 01:32:48 and then give the link of the resulting page Apr 24 01:33:42 I tried ...SOMEUNIQUEIDENTIFIER AND GOT THIS: This page has been removed! This page is no longer available. It has either expired, been removed by its creator, or removed by one of the Pastebin staff. Apr 24 01:33:55 vagrantc wasn't being helpful Apr 24 01:34:23 i apparently didn't guage the situation correctly Apr 24 01:34:29 all you do is go to pastebin.com, paste your text into the big text field, and then click the "Create New Paste" button at the bottom of the form Apr 24 01:34:49 it'll turn the text you pasted into a (temporary) web page Apr 24 01:35:04 regardless of outcome , thanks for your help & attention - I'll try again Apr 24 01:37:36 Ok, before I clocked the [+ New Paste] button. I guess its different than [Creat New Past]. Apr 24 01:38:52 ehh, I can see the confusion but that's just literally a link to the homepage Apr 24 01:39:06 ok, thx Apr 24 01:40:03 so... ehm... url? Apr 24 01:40:42 maybe this is it: https://pastebin.com/SFSFFkTh Apr 24 01:40:56 there we go Apr 24 01:41:55 ehh, it looks to me like you're trying to install packages from the internet while the beaglebone doesn't have internet access Apr 24 01:42:05 sorry if I seem so dumb but this stuff is all new to me (although I've been an EE for a few decades) just not so much in Linux or IRC. Apr 24 01:42:26 using pastebin is neither linux nor irc related :P Apr 24 01:43:10 yup, understood - I just never used it before but my problem is that I cannot get the BBG to install a new node. Apr 24 01:43:22 the existence of this paste, created mere minutes ago, shows all sorts of people use pastebin for all sorts of purposes: https://pastebin.com/JeEbND5t Apr 24 01:44:18 yeah, I can see that, I just always used stuff inside my place of work. Now I'm unemployed and on the outside. Apr 24 02:27:12 Hello... **** ENDING LOGGING AT Tue Apr 24 03:00:01 2018
