Feb 29 03:06:21 Yea boy! Feb 29 03:06:34 mjpeg-streamer is a mother. Feb 29 03:06:48 motion jpeg bleah. Feb 29 03:06:49 Has anyone successfully used this source on the BBB? Feb 29 03:06:56 Come on. Feb 29 03:07:13 that sounds like you're trying to use a camera, which already sounds like a painful experience Feb 29 03:07:17 on a BBB Feb 29 03:07:24 I am on a BBGW w/ a Cape on it! Feb 29 03:07:25 Ha. Feb 29 03:07:28 I understand. Feb 29 03:09:31 here https://pastebin.com/mb0FEcQ6 Feb 29 03:10:01 I got it! Feb 29 03:10:08 Boo-ya! Feb 29 03:12:07 Now, to try w/ another board. Feb 29 03:12:33 This cape add on and BBGW pin config might deter me from publishing my pretty face all over the web. Feb 29 03:12:43 Can't other BBB broke SD-clot Feb 29 03:13:25 BBGW = BB Green? Feb 29 03:13:54 BBGW = BB Green Wireless Feb 29 03:14:36 Messages still coming out on console. Reboot? Feb 29 03:14:41 But, the pins are used for other things outside of just general use, i.e. for WiFi and some other things. Feb 29 03:16:09 green wireless, i.e. the most "deep sigh" beaglebone family member Feb 29 03:19:30 zmatt, what do think about messages? Feb 29 03:19:44 ? Feb 29 03:19:59 oh sorry, missed it Feb 29 03:20:02 Ha. Feb 29 03:20:22 https://pastebin.com/mb0FEcQ6 Feb 29 03:20:25 He read what I typed and flipped. Feb 29 03:20:27 Ha. Feb 29 03:20:30 yaeh I saw it now Feb 29 03:20:59 did you unmount the card before removing it? you didn't, did you? :P Feb 29 03:21:35 yep sudo umount /mnt/sd Feb 29 03:21:39 hmm Feb 29 03:22:45 some kernel task is still trying to finish removing the block device it looks like Feb 29 03:23:55 I'm not sure why it doesn't get unstuck though, I'd assume it should be able to realize that the block device is gone and just complain and move on Feb 29 03:24:42 it's also odd that it wasn't done with the block device after doing an unmount.. you'd kinda hope unmount doesn't complete until the last block I/O to the device is done Feb 29 03:25:36 though I'll admit with sd cards I do tend to be a bit paranoid and do a "sync" or two after unmounting, and then wait a second just to be extra sure :P Feb 29 03:26:58 anyway, probably best way to get this task unstuck rigth now is the reset button ;) Feb 29 03:31:03 ok did sudo reboot it's loading Feb 29 03:31:28 reboot worked? I wouldn't have been surprised if it'd get stuck Feb 29 03:31:38 (while shutting down that is) Feb 29 03:32:27 yea got [ 6870.592337] systemd-journald[877]: Failed to send WATCHDOG=1 notification message: Connection refused Feb 29 03:32:44 that's odd Feb 29 03:33:03 reminds me I went to all the trouble of making an SD card to reflash my BBB ... duh. Feb 29 03:35:30 ok it's back up. going to try mount sd again Feb 29 03:39:34 Ha it thinks its Sun Oct 7 17:41:15 UTC 2018 . that sync must have done the trick. Feb 29 03:40:08 it still fails to synchronize automatically? Feb 29 03:40:21 what does "systemctl status systemd-timesyncd" say? Feb 29 03:41:52 remember i have to setup internet again Feb 29 03:43:18 oh right Feb 29 03:43:23 yeah, no internet, no ntp Feb 29 03:43:36 "setup" in what sense though? typically you plug in ethernet and you're done Feb 29 03:44:40 setup different gateway and ip address. will do tomorrow Feb 29 03:44:47 no dhcp? Feb 29 03:45:11 am going via internet sharing on windoze Feb 29 03:46:09 don't worry lots accomplished tonight things to do tomorrow Feb 29 03:46:17 ah yeah, in those cases I'd just set the PC to bridge between the usb and ethernet interface and configure the bbb to use dhcp Feb 29 03:46:57 (or in case the PC uses wifi then plain internet sharing, plus bbb in dhcp mode) Feb 29 03:47:50 been there with internet sharing p.c. want to use 192.168.137.2 not 192.168.7.2 Feb 29 03:48:31 I generally don't see a good reason to bother with manual IP configuration Feb 29 03:48:39 have some tea relax. something to do tomorrow Feb 29 03:48:56 long live dhcp (and/or ipv6 stateless autoconfiguration) Feb 29 03:49:42 oh stateless as in new jersey Feb 29 03:49:50 lol Feb 29 03:50:35 i'm gonna sign off for tonight guys. Feb 29 03:50:49 stateless as in addresses are MAC-derived hence don't actually need to be allocated/assigned by a dhcp server Feb 29 03:50:51 thanks for all your help! Feb 29 03:51:22 Hmmm ciao sleep don't forget Feb 29 03:51:23 (the router just hands out the prefix and gateway information but doesn't need to be involved in address allocation) Feb 29 03:51:33 ok, good night :) Feb 29 03:51:38 Hey! Feb 29 03:52:24 If I have access via a server and my usb cam is not stating video evidence of my movement, what then? Feb 29 03:52:34 Do I need another board or try another program? Feb 29 03:53:25 Has anyone used mjpg-streamer for usb cam video on the BBB or related boards? Feb 29 04:02:53 Hello? Feb 29 04:03:32 I have done it w/ a .c command on the terminal but w/ no video output (yet). I need to know things, man! Feb 29 04:09:08 Okay, forget the video stuff. How can I install cloud9 on the BBB? Feb 29 04:21:47 Forget it. Sheesh. Feb 29 14:29:51 set_ cloud9 is normally installed in the BBB Feb 29 14:29:59 the default image has it on it. Feb 29 14:43:19 I understand. I erased years ago for some reason. Feb 29 14:46:02 I erased the cloud9 IDE years ago for some reason. Feb 29 14:53:16 at least you have yourself. Feb 29 14:54:48 you have numerous options. Right now I should be reflashing my BBB but instead I am tintinnabulating my keyboard Feb 29 14:55:57 huh now that would be cool a keyboard with haptic response from audio so that each keystroke sounded and felt like a manual type writer. Feb 29 14:58:11 I have loadable modules turned off in my kernel on my BBGW. Is there a way to turn them on? Feb 29 14:58:45 w/out compiling? Feb 29 15:03:33 that's weird they should be on by default. Feb 29 15:05:09 that's a kernel build flag I think ... why is it turned off?! Feb 29 15:05:35 I do not know. Feb 29 15:06:07 I am trying to install a driver and I cannot b/c of kernel modules being turned off by default. Feb 29 15:08:20 Yea. I got a build flag. Kernel modules are turned off. Feb 29 15:09:25 is there a way to turn on the loadable kernel modules w/out having to compile the entire linux kernel? Feb 29 15:36:39 set_ you got your ears on? Feb 29 15:44:39 sort of... Feb 29 15:44:48 Shoot! Feb 29 15:46:15 I am about to get ready for the day but I will check back shortly. Feb 29 15:50:02 it 7-8 ish his time Feb 29 16:04:19 See the deal on eBay NEW BBB Rec-c $49 but the guy took my offer for $45. https://www.ebay.com/itm/124047160802 Feb 29 16:04:57 Good price huh? Gut has some left. Element-14 Feb 29 16:16:05 $45.00 make you holla! Feb 29 16:16:09 bbl! Feb 29 16:30:56 I'm deciding on ordering one after my offer $45 was excepted Feb 29 16:31:25 ho would not take $40. I tried. Feb 29 16:54:33 Can't get USB up getting: [FAILED] Failed to start Raise network interfaces. Feb 29 17:05:40 Check out: https://pastebin.com/590gUFuG Feb 29 17:16:37 HI, I downloaded SDK RTOS from the link http://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/latest/index_FDS.html. I downloaded .bin file, as my host PC is linux. While installing it, towards the end of installation something goes wrong, and gives errors (which we can skip over). But, after creating SD card for same sdk, it fails with an error Feb 29 17:16:37 "SD card file directory doesn't exist. Feb 29 17:16:49 Can anyone help me resolving this error? Feb 29 17:42:13 that's a TI thing, ask on the TI e2e forums Feb 29 20:19:06 Hi all, I am new to beagle bone. I was wondering if the hardware implementation for the chip inside beaglebone is also open source? Thank you Feb 29 23:02:45 No .. Feb 29 23:04:33 the chip isn't open source the design for the BBB is. Feb 29 23:07:03 ok thanks.. Mar 01 00:21:12 Oh. So, what you are saying is that the mfg. process for the chip is not open source, right? Mar 01 00:21:22 But... Mar 01 00:21:33 The TRM is available for each pin description. Mar 01 00:22:23 Each ball and pin on that sucker is available via the TRM of the chip, right? Mar 01 00:30:28 Right the IC is someones property but they give you information on how to use it (or they couldn't sell it). Mar 01 00:30:55 They wouldn't earn money if they gave away the IC design information :D Mar 01 00:33:38 It's more about the implementation than the design for my interests Mar 01 00:37:56 Do you know about the TRM? Mar 01 00:38:08 am335x TRM. Mar 01 00:42:32 Just googled it -- found the technical manual Mar 01 00:42:47 but its the API description Mar 01 00:42:56 not the actual implementation right? Mar 01 00:47:52 Oh. Mar 01 00:48:03 You want the BBB Rev. C RM. Mar 01 00:48:28 When you type implementation, what exactly are you doing w/ this implementation? Mar 01 00:48:50 yep, Mar 01 00:48:52 Like, a library in python or a .c library? Mar 01 00:49:36 i am interested in understanding the compilation from the specs documentation (ISA specifications) to the actual implementation Mar 01 00:49:44 If you are looking into libraries in python3 or libraries in c/c++, there are a few. Mar 01 00:49:47 Oh. Mar 01 00:50:12 can you share the libraries? I'll look into that Mar 01 00:50:21 Okay. Please hold. Mar 01 00:50:39 but i thought that since bbb was opensource the chip would be too Mar 01 00:51:15 https://github.com/shabaz123/iobb is one I found online a while back. There is also Adafruit_BBIO. Mar 01 00:52:04 I usually do not type up entire libraries for use on the pin configuration on the BBBs but it has interested me for some time now. Mar 01 00:52:25 How, why, when, for whom, and etc. Mar 01 00:52:36 Oh! Mar 01 00:52:40 And bonescript. Mar 01 00:53:22 cool thanks I'll check these out... Mar 01 00:53:25 There is a javacript, node.js, bonescript server that the images come w/ these days w/ specific usage for pins. Mar 01 00:54:10 PWM, ADC, GPIO, UART, i2c, and etc. I think libraries are lacking in this field but the ones that are available do work. Mar 01 00:55:03 human2366mall: Are you trying to make things work, e.g. set up servers, actuators, and/or sensors? Mar 01 00:56:09 not really, I am looking to understand the hardware implementation for attacks such as spectre and meltdown Mar 01 00:56:31 and see if they are applicable in small performing processors too Mar 01 00:56:47 Oh. Mar 01 00:56:48 Okay. Mar 01 00:57:02 Good luck. So, you are a security person? Mar 01 00:57:07 yep Mar 01 00:57:11 thanks Mar 01 00:57:11 neat. Mar 01 00:57:15 No issue. Have fun! Mar 01 01:01:39 Yo! Mar 01 01:02:27 set_ Are you aware of any prolems/issues with element-14 BBB? Mar 01 01:11:41 Any body around? Mar 01 01:25:08 Hey. Mar 01 01:25:09 No. Mar 01 01:25:25 No issues I know about. Are you sure it is from element14? Mar 01 01:25:44 What version is it? Mar 01 01:26:03 Rev. C or Rev. A5B or something else? Mar 01 01:26:40 KenUnix: I know some of the older models had a 2GB eMMC on them. Mar 01 01:31:07 So... Mar 01 01:31:39 If you are trying to cram a 4GB image on to a 2GB, it will just not work. Mar 01 01:31:52 Are you using a SD Card instead? Mar 01 01:40:52 No I was reading about a boot from SD on element-14 BBB. Mar 01 01:41:57 Oh. Mar 01 01:42:12 What did it say, i.e. the summary. Mar 01 01:42:14 ? Mar 01 01:42:28 It said: IMPORTANT: On Rev C BeagleBone Blacks from element14, you need to create a folder titled "dtbs" and copy am335x-boneblack.dtb into it in order for the SD card to be booted. Mar 01 01:42:38 Old stuff. Mar 01 01:43:05 I think I have one of those element14 BBBs. Mar 01 01:43:16 OK now. Good I should go ahead and get one for $45 then Mar 01 01:43:30 I have never once heard of that idea nor have I listened to it. Mar 01 01:43:37 Oh. That is your choice. Mar 01 01:43:57 What's ya mean? Mar 01 01:44:25 They have more reputable co's than ebay.com. ebay.com is usually, from what I understand, for used items that people are willing to pay less to get. Mar 01 01:45:05 Wait. Mar 01 01:45:10 For instance...if my BBB costs $58.00 new w/ packaging. Ebay.com will sell, specific sellers, for a fraction of the cost b/c it was used. Mar 01 01:45:49 See here: https://www.ebay.com/itm/124047160802?ul_noapp=true Mar 01 01:45:57 I mean. How else can they sell items that cost $100.00 for $25.00. Mar 01 01:47:24 Well, they are selling it as new. Maybe b/c it is a dated item, they can sell it low to sqaush inventory. Mar 01 01:48:15 Well adafruit has em for $55 Mar 01 01:48:38 good old Ada always getting the good stuff :D Mar 01 01:48:42 Ha. Mar 01 01:48:45 yea boy! Mar 01 01:49:00 I got an "expensive" GPS module from them once. Mar 01 01:49:16 yea man https://www.adafruit.com/product/1996 Mar 01 01:49:20 I burnt it the second time trying to solder on some pins to it. Ouch. Mar 01 01:50:15 Oh I found what seems like a good wifi adapter usb 2.0 compatible & debian compatible $19 Mar 01 01:50:45 Technically speaking they could just use an OSD3358 instead and make a WiFi BBB with a wired network interface instead. Mar 01 01:50:53 Lesson learned: Do not try to heat the pads too long while soldering joints. Mar 01 01:51:09 Bzzt. Burn. Mar 01 01:51:56 Here: https://smile.amazon.com/gp/product/B002UVNW5W/ref=ask_ql_qh_dp_hza Mar 01 01:52:00 Yea. KenUnix: I would go w/ the BBBW instead. It is nice, has the power adapter interface, and known-to-work WiFi. Mar 01 01:52:45 Getting all those wifi dongles to work out of the box is not easy, it is time consuming, and will make you repeat several steps over and over and over and... Mar 01 01:54:14 How do you access your BBBW? Mar 01 01:54:28 ssh Mar 01 01:54:57 Are you using the USB port. Oh we've been there. Mar 01 01:54:58 I usually use ssh or a PuTTY terminal if I am using Windows. Mar 01 01:55:08 USB! Mar 01 01:55:26 Can you access via wifi? Mar 01 01:56:17 Good question. I have used, personally, wifi on the board to run a bot. Mar 01 01:56:28 I can control the bot via online pages. Mar 01 01:56:37 But... Mar 01 01:56:58 If you are asking about networking, that might be for another person to answer. Mar 01 01:57:07 I have not tried w/out USB. Mar 01 01:57:23 Me thinks that's a bigger then USB. Mar 01 01:57:31 Yea. Mar 01 01:57:32 But think. Mar 01 01:57:56 You would need an interface on your touch screen for computation, i.e. like a regular computer. Mar 01 01:58:14 I do not think this board is meant to be handled like a regular computer. Mar 01 01:58:57 "embedded" is the key word that makes me think that wifi networking should be handled on a smaller application in regards to the BBB. Mar 01 01:59:03 That is how i look at it. Mar 01 01:59:09 That's what i mean. Wifi would be good for downloading sudo apt and the like Mar 01 01:59:30 Hmmm. Mar 01 02:00:18 So, what should I do to sell this idea? I mean it. Do I plug in my keyboard, my mouse, and a usb hub to make the board work w/ wifi and sudo apt install python3-pip? Mar 01 02:00:40 I don't think you can mange it over wifi unless you browse to it bring up cloud-9 ide then you can get to a shell Mar 01 02:01:12 Oh. THere is a shell on the board if you install it, i.e. xfce4. Mar 01 02:01:26 That one is known to work for me. Mar 01 02:02:03 KenUnix: I can plug in a board w/ LCD Screen (touch) right now and find out. Should I is what I was trying to ask. Mar 01 02:02:28 it's still the problem of getting there over wifi. And the broswer to beaglebone is kina insecure Mar 01 02:02:43 Oh. Right. Mar 01 02:02:46 You are right. Mar 01 02:02:53 But...there is shell. Mar 01 02:02:58 BASH! Mar 01 02:03:07 I am missing something. Mar 01 02:03:44 need some password protection when assessng via wifi Mar 01 02:04:06 I think that the board may be able to, w/ made application (socket or service), access wifi during boots outside of USB connections. Mar 01 02:04:14 Should I try it? Mar 01 02:04:41 KenUnix: Is that what you are trying to do at times? Mar 01 02:05:18 it is a concern especially if it's on wifi Mar 01 02:05:42 Okay. So, you are going to use another persons wifi and you need to protect your data? Mar 01 02:06:48 No. You don't want the block able to assess BBB. Mar 01 02:07:35 well SSH is nice to use and if you are transferring files using filezilla with sftp works great. So putty to get a shell and sftp to send files works well. It is true wireless connections are inherently not secure. Mar 01 02:08:38 Oh. Mar 01 02:08:40 I got you. Mar 01 02:09:28 I have my cape on the wrong board. Mar 01 02:09:33 Dang it. Mar 01 02:09:44 I just plugged in everything. Mar 01 02:10:15 I know something weird will happen if I take off the cape on this BBG. Mar 01 02:10:18 your lesson for the day is be sure you are doing what you want to. Mar 01 02:10:26 Ha. Mar 01 02:10:28 Yeppers. Mar 01 02:25:10 hmm I wonder if one can remotely debug pydev on the BBB Mar 01 02:29:29 Shute now i can't web browse into my BBB Mar 01 02:30:43 I can ping, ssh, ftp but browsing just times out. Me thinks i removed a wrong program. Mar 01 02:31:16 i don't know what's needed for apache to work Mar 01 02:41:09 Me thinks start over and burn a new image Mar 01 02:55:48 Browsing on the BBB is not easy on the system. **** ENDING LOGGING AT Sun Mar 01 02:59:57 2020
