Sep 22 11:38:08 |Jeroen|: find somebody wo has some to give away for free, maybe used ones or such :-) Sep 22 11:38:36 <|Jeroen|> ok, second question: Who wan't to give me a beaglebone for free :p Sep 22 11:39:29 but given the fact thats they're only ~50€ at digikey anyways... Sep 22 11:40:38 <|Jeroen|> but digikey is 18,00 € shipping Sep 22 11:41:09 conrad isn't much more etc. Sep 22 11:42:08 <|Jeroen|> yeah Sep 22 11:42:43 <|Jeroen|> silly the pocketbeagle doesn't have ethernet Sep 22 11:43:02 i'd rather call it logical, given the size. Sep 22 11:43:40 <|Jeroen|> nah its essential, better removed the sd then Sep 22 11:43:57 *shrug* use cases differ. Sep 22 11:44:05 <|Jeroen|> how can u control anything whit it whitour ethernet or wifi ? Sep 22 11:44:21 it has gpios and uarts? Sep 22 11:44:40 not everything has to be "network connected" Sep 22 11:44:52 <|Jeroen|> yes it does, IOT age! Sep 22 11:56:47 Anyone experienced with beaglebone ADC please ??? Sep 22 11:59:54 try asking real questions Sep 22 12:08:53 Hello Sep 22 12:16:00 I have applied 1volt DC to AIN input (from a lab power supply and checked with 1mV resolution voltmeter) , ADC reading is costantly varying about 20/30 point (of 4096 available), is this a normal behaviour ? Sep 22 12:16:14 Thanks Sep 22 12:18:43 fred_tv: I suspect that's par for the course. I'd recommend to check the TRM for the SoC or there might be even something specific about the ADC Sep 22 12:18:54 As 4096 steps over 1.8V gives about 0.44 mv per bit , it seems reading is unstable on the range of about 13mv Sep 22 12:19:09 it's certainly not the best ADC, IIRC it's mostly for touch screen applications Sep 22 12:19:36 well. the last few bits are garbage, don't expect too much Sep 22 12:20:35 if you need high resolution, you'll have to connect a high quality external ADC Sep 22 12:21:47 i envisage to use BeagleBoard to develop a new product, i have some specific needs so i have to select the good hardware environment with the good capes, modules, .... Can anyone give me the way to design my architecture ? I need 2 UART, eMMC available, and 3GPIO availables (1output et 2inputs), on BBBK because of its operating temperatures. Sep 22 12:22:02 I'm trying to read mains current and voltage , so the readings have to be scaled down to the 0-1.8V range so it's easy to add errors... It is acceptable anyway... ! Sep 22 12:23:08 ineo: eMMC and industrial temperature range are mutually exclusive from what I understand Sep 22 12:23:55 yes, and i would like to keep 2UART, one for a BLE module and one for an RFID module. Sep 22 12:25:34 https://beagleboard.org/arrowbbbi Sep 22 12:25:46 https://www.element14.com/community/docs/DOC-78671/l/eement14-beaglebone-black-industrial-4g-based-on-sitara%C3%A3-%C3%A2-am3358-processor Sep 22 12:28:06 wow ! good ^^ Sep 22 12:31:56 ah, it was the very first industrial spin that had no eMMC. Sep 22 12:35:20 the arrow's has it, no ? Sep 22 12:35:24 on the page i see : Sep 22 12:35:25 Program Memory Type: Embedded MMC Flash Sep 22 12:36:27 yes, the one without isn't produced anymore for a long time anyway Sep 22 12:36:38 both the arrow and the E14 seem to have eMMC Sep 22 12:38:51 on the doc, i see that the board have 6xUART. But are they useable ?? Or are they used by functionnalities of the board ? like eMMC ? Because i need to communicate with modules, i need to manage a display to, and have 3 IO, is it possible to do all of this with 1 alone BBK ? Sep 22 12:40:04 there is a SRM for the E14 board Sep 22 12:40:11 I'd recommend consulting that Sep 22 12:40:19 I'm having problems getting the wifi to work on Beaglebone Black Wireless. I've tried Debian 4.4.3, 9.1 and 8.6. They just cannot see the wlan0 port. If I run connman and try to turn the wifi on it always comes back with - Error enabling wifi tethering: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist. Has anyone come across this before? Thanks. Sep 22 12:40:22 and there are various pinmux calculators Sep 22 12:41:08 i will look about this. Thanks you for your responses ;) Sep 22 13:18:30 Hello! Could someone help me open the serials port on a BBB? Sep 22 13:18:48 i'm following this guide: http://beaglebone.cameon.net/home/serial-ports-uart Sep 22 13:18:57 but i doe'nt work Sep 22 14:03:03 hi there channel :-) Sep 22 14:06:32 it's curious in windows... this beaglebone black browse beaglebone.local/bone101/Support/bone101 Sep 22 14:06:50 in linux it doesn't Sep 22 14:13:30 Hello, I'm using beaglebone black with 7inch display from 4D systems (4DCAPE-70T) Sep 22 14:13:45 Final goal is to setup cross-compile environment with QtQuick support. Sep 22 14:13:50 Buildroot looked promising... But can't make display operational. Sep 22 14:14:12 Here are the few steps I took and serial output: https://pastebin.com/9n7Ativt Sep 22 14:14:51 I've noticed the file autorun [DeviceInstall] DriverPath=Drivers\Windows\src\files\RNDIS ; riverPath=Drivers\Windows\src\files\FTDI ; riverPath=Drivers\Windows\src\files\CDCACM Sep 22 14:15:06 My guess is that first problem is in uEnv.txt, also some kernel drivers could be missing also. Sep 22 14:16:04 that's why Sep 22 14:16:38 deod, are you talking to me? Sep 22 14:16:55 nope, sorry just asking for help Sep 22 14:17:15 I'm stuck with capemgr and LCD Sep 22 14:17:39 deod, all right... sorry Sep 22 14:18:53 duty, have you played with capemrg configuration? Sep 22 14:20:00 dury, have you played with capemgr configuration? Sep 22 14:20:07 deod, no... just testing the main board with different linux releases Sep 22 14:20:57 deod, I haven't got that cape though Sep 22 14:21:53 dury, thank's anyway. Sep 22 14:22:44 Is it possible to edit autorun file to put linux driver path Sep 22 14:25:04 I tried that... connecting the board by USB, and not success Sep 22 14:27:45 how to connect to http://beaglebone.local/bone101/Support/bone101 in linux? Sep 22 14:29:55 Deod, sorry, that pastebin is a path to make serial port working? Sep 22 14:30:57 That was my try is setting up the beaglebone black with buildroot - in general Sep 22 14:31:09 dury: visit that url with a web browser (assuming you're on the same network as the beaglebone and its hostname hasn't changed) Sep 22 14:31:20 I was hoping if I use defconfigs it will work... out of the box :) Sep 22 14:32:23 tried first with TI kernel... few builds where necessary to confirm that no capemgr will com out of TI kernel Sep 22 14:32:48 MathOnNapkins, which url u mean? Sep 22 14:33:09 dury: if you can't ping beaglebone.local try pinging beaglebone instead and see what you get. If you can pingle a device called beagle bone, replace beaglebone.local with beaglebone in the URL. Sep 22 14:33:36 dury: the URL you pasted earlier ("http://beaglebone.local/... ") Sep 22 14:33:53 lol pingle Sep 22 14:34:14 MathOnNapkins, sorry... all right Sep 22 14:34:20 then I switched to beaglebone krenel with bb.org Sep 22 14:35:34 MathOnNapkins, this is rev. A5C only 2gb eMMC though Sep 22 14:35:44 so? Sep 22 14:36:46 MathOnNapkins, better angstrom than other distros... what you think? Sep 22 14:37:22 I used to use Angstrom and I thought it was all right, but all our customers have asked us to standardize on Debian. Can't really do much Sep 22 14:37:50 I will say that Angstrom's package management was a tad less complicated to deal with Sep 22 14:39:44 MathOnNapkins, mine is running this image "BBB-blank-debian-8.9-lxqt-2gb-armhf-2017-09-01-2gb.img.xz" Sep 22 14:40:53 Seems like that should be fine. It's fairly recent. Sep 22 14:42:07 MathOnNapkins, it takes hardly most of eMMC, though Sep 22 14:42:43 MathOnNapkins, not room for more, jeeesssuuuuss Sep 22 14:43:15 dury: You have to choose your poison at some point Sep 22 14:43:42 MathOnNapkins, what you mean? Sep 22 14:44:51 dury: Most of the 2 gb images, even Angstrom, don't leave much room on the eMMC. It's been that way a long time. You can always uninstall packages you don't need after flashing the image Sep 22 14:45:19 MathOnNapkins, right I see Sep 22 14:45:20 dury: Or boot off of an SD card larger than 2 GB. Honestly I prefer doing it that way with Rev A / B boards Sep 22 14:46:50 MathOnNapkins, so you boot those boards from sd-card, don't you? Sep 22 14:47:07 Rev A and B boards, yeah Sep 22 14:47:21 MathOnNapkins, right Sep 22 14:48:46 MathOnNapkins, what's the eMMC of those? Sep 22 14:49:18 dury: 2 GB. Like yours Sep 22 14:49:18 MathOnNapkins, 2GB ? Sep 22 14:49:23 sorry Sep 22 14:49:32 right Sep 22 14:49:34 Rev C and up has 4 GB Sep 22 14:50:06 I have already ordered one though Sep 22 14:51:10 MathOnNapkins, really appreciate your your advices... believe me Sep 22 14:51:27 dury: Okay, I don't feel like I told you much but good luck! Sep 22 14:51:53 MathOnNapkins, don't go please Sep 22 14:52:20 MathOnNapkins, I'm going to connect the board by usb to a linux box Sep 22 15:01:05 MathOnNapkins, a beagle icon appears on desktop double click on it and I clicked on START.htm one step on green saying Power and boot ... that's all Sep 22 15:05:51 MathOnNapkins, if I type just beaglebone in the browser. it goes beaglebone.org though Sep 22 15:06:51 dury: try http://192.168.7.2/bone101/Support/bone101 Sep 22 15:08:49 MathOnNapkins, nothing does Sep 22 15:09:26 the connection has timed out Sep 22 15:10:57 MathOnNapkins, maybe should I edit autorun.inf Sep 22 15:14:07 dury: I've never had a problem talking to a Beaglebone like that from Linux. Can't help you there. The only problem I ever had was sharing my internet connection with the Beaglebone. autorun.inf only applies when you're running Windows. Sep 22 15:15:42 MathOnNapkins, which linux are you running there? Sep 22 15:16:26 Ubuntu and Fedora Sep 22 15:16:49 MathOnNapkins, here is debian Sep 22 15:17:59 MathOnNapkins, jeessuuss can't go 2 step :-( Sep 22 15:22:09 MathOnNapkins, if I connect the ethernet cable together with hdmi and usb keyboard like normal computer it's not problem Sep 22 15:22:44 MathOnNapkins, but only by usb can't Sep 22 15:24:11 Dury: You know you can do both at the same time? Put it on ethernet with a monitor and also tether it via USB to another computer. I'd try that and see if that gives you some clues as to why it's failing Sep 22 15:24:55 yocto 1.5 dora and beaglebone black, impossible? Sep 22 15:26:30 MathOnNapkins, tether it .... what's that ? what you mean? Sep 22 15:27:01 dury: tether = connecting a beaglebone to a PC with a microusb cable Sep 22 15:27:12 *miniUSB Sep 22 15:29:14 MathOnNapkins, one minute Sep 22 15:30:49 MathOnNapkins, got power supplier too. should I or miniusb it's enough? Sep 22 15:32:00 Dury: Personally, I'd plug in the power supply, plug in a monitor, plug in ethernet. check that it works fine with the monitor and that you can see it on the network from a PC Sep 22 15:32:12 Then I'd tether it and see if you can get that working Sep 22 15:34:36 MathOnNapkins, well as a normal pc it does Sep 22 15:36:19 MathOnNapkins, I mean plug the power supply, monitor by mini hdmi, ethernet and cordless keyboard by usb Sep 22 15:37:08 MathOnNapkins, that way 192.168.7.2 works Sep 22 16:02:58 goes so slow though Sep 22 16:06:22 I think to downgrade to the latest angstrom it will be better with this rev A5C, MathOnNapkins. what you think? Sep 22 16:09:19 be back in other time Sep 22 18:57:12 angstrom /o Sep 22 18:57:15 /o\ Sep 22 18:57:19 why oh why Sep 22 19:44:44 zmatt: nostalgia? maybe? Sep 22 20:06:00 Hey there. Looking to know what is the quickest/easiest way to acquire the serial number of a Beaglebone Black that is fresh out of the box Sep 22 20:38:37 Dear community, I am learning UBoot on BBB. I have been struggling to get a stable usb0 interface to show up on the hostside. "ifconfig usb0 up" does bring up the interface, but it disappears soon after triggering a dhcp boot on target BBB: Kindly suggest when to look further, thanks! Sep 22 20:40:05 that sounds like perfectly normal behaviour Sep 22 20:41:00 once you load a kernel via dhcp boot (or any other means), it's then up to linux to setup the usb network interface again if desired Sep 22 20:42:58 zmatt: I did follow your recommendations to get the uImage running after a long week. But now, the system went back to the old state where uBoot request for IP address and the host has no usb0 interface to bind the dhcpd server to. Sep 22 20:43:36 I'm not followeing Sep 22 20:43:41 *following Sep 22 20:45:25 So, at the moment my uboot is configured for usb_ether. On u-boot dhcpboot, I expect the host to assign an IP to target BBB. Sep 22 20:46:15 but the host doesn't have an active usb0 interfcace so the dhcp server cannot bind to it and no ip assigned to target hence Sep 22 20:46:17 if you're trying to bring the system up entirely via usb, it should appear as network interface four times: first by ROM to load MLO, then by MLO to load u-boot.img, then by u-boot to load kernel+dt+initramfs (or FIT), finally by the kernel itself for the nfsroot Sep 22 20:47:31 atleast for now, I only want to bring kernel image from USB. The uboot loads from eMMC Sep 22 20:48:46 ok. so you're saying it appears as usb network interface but disappears again when you attempt dhcpboot ? Sep 22 20:48:57 (and does so before it loads anything) Sep 22 20:49:48 exactly Sep 22 20:52:01 to be precise: after issuing dhcpboot from target, it get this: Sep 22 20:52:01 [ +0,005787] cdc_subset: probe of 1-2:2.0 failed with error -22 Sep 22 20:52:01 [ +0,002325] rndis_host 1-2:2.0 usb0: register 'rndis_host' at usb-0000:00:14.0-2, RNDIS device, de:ad:be:af:00:00 Sep 22 20:52:21 and then ifconfig up usb0 on host side Sep 22 20:53:06 uh, okay, you just said it disappeared as usb device, but this sounds like it (re)appears just fine Sep 22 20:54:55 the dmesg log was from host side after I trigger dhcpboot. but nothing really happens Sep 22 20:55:19 I remains idle after [ +0,019968] IPv6: ADDRCONF(NETDEV_UP): usb0: link is not ready Sep 22 20:55:47 strange Sep 22 20:55:52 I expect link to be up after this point, but it doesn't happen on host side Sep 22 20:56:10 and when I force it up on host, it shows up Sep 22 20:56:35 but no more dhcp activity after that Sep 22 20:57:07 no idea, this worked for me Sep 22 20:57:22 could you please suggest any tool for sniffing usb0 activity on host side Sep 22 20:57:30 tcpdump Sep 22 20:57:54 (or any other packet sniffer) Sep 22 20:58:22 as in, would you suspect any udev or other activity that is malfunctioning Sep 22 20:59:02 I did try wireshark and tcpdump.. but since no usb interface to probe it remains silent Sep 22 20:59:48 well the link does need to be brought up obviously, that doesn't happen automatically Sep 22 20:59:56 normally the job of whatever network manager you use Sep 22 21:04:25 I have assigned a static ip to usb0 in /etc/network/interfaces and configed the dhcp server to listen to usb0. Sep 22 21:04:25 So, I assume the dhcp server is triggered to serve [Active] only when the usb0 interface is up Sep 22 21:05:01 and when the interface goes down, the server is no longer active Sep 22 21:05:36 Is my understanding right Sep 22 21:05:36 that sounds awkward given that the usb0 interface will dynamically appear Sep 22 21:07:15 the host side usb interface itself is static assigned and the dhcp server binds to it once the iface is up. Sep 22 21:07:42 but should this interface always remain up? Sep 22 21:07:45 I use systemd-networkd to automatically bring up usb0 when it appears (and configure a static ip). I use dnsmasq as bootp/dhcp/tftp server and its "bind-dynamic" option to be able to automatically bind to the interface whenever it appears Sep 22 21:08:14 it can't remains always up since it will only appear once you execute dhcpboot in u-boot Sep 22 21:08:29 *remain Sep 22 21:09:22 Thank you for confirming. Is dnsmasq a lighter version of isc dhcp server? Sep 22 21:09:41 it's just a completely different program. I have no experience with isc dhcp server Sep 22 21:10:10 ok, I will try with your setting. Sep 22 21:11:17 here's my dnsmasq.conf, some settings will obviously need to be tweaked for your environment -> https://pastebin.com/raw/5L4JXd3t Sep 22 21:12:14 ah, I misspoke when I said "MLO" earlier, I meant the SPL (as raw binary, not as MLO) Sep 22 21:12:31 not relevant for you anyway as long as u-boot is on eMMC or SD Sep 22 21:12:49 np, I get it Sep 22 21:13:12 thanks, I shall try it and inform Sep 22 21:15:11 hi there channel :-) Sep 22 21:15:34 dury: no, why would you want to downgrade to angstrom?! Sep 22 21:15:37 :) Sep 22 21:19:50 beside me BBB rev. A5C 2GB eMMC running jessie 8.9. /dev/mmcblklp1 size 1.8G used 1.6G avail 26M wanna make more room and faster. how to? Sep 22 21:20:15 install less stuff? Sep 22 21:20:40 (or use a prebuilt image with less stuff installed, or remove useless stuff from prebuilt image) Sep 22 21:21:12 faster... depends on what you mean. nothing is magically make the processor faster obviously Sep 22 21:21:18 zmatt, can you drive me how to do it please? Sep 22 21:21:20 *going to make Sep 22 21:22:44 jesssuss LXQt as win manager Sep 22 21:23:28 which packages should I uninstall Sep 22 21:23:40 do you really need a complete desktop environment? a beaglebone is probably never really going to make a comfortable desktop computer anyway Sep 22 21:24:10 I can't decide for you what to keep/install and what to remove, that depends on what you want on it Sep 22 21:24:41 generally it's easier to start with a minimal image and just install stuff you want than it is to figure out what you don't need/want and is safe to remove Sep 22 21:27:49 right.... what's the process to install minimal image with light desktop environment on 2GB eMMC? Sep 22 21:28:20 no idea, I've never run any desktop environment on any beaglebone Sep 22 21:28:36 right I see Sep 22 21:28:42 but in general, flash the minimal image, and then install what you want Sep 22 21:31:24 and if you're going to get close to filling up eMMC (not the best idea, but not sure how well you can avoid that with a desktop environment), you may want to avoid installing all needed packages at once since installation requires both the package itself (.deb) and the installed files, and only after install is complete can the downloaded .debs be removed :) Sep 22 21:31:43 do you know any minimal image to start with...? boot it from sd-card and install in eMMC Sep 22 21:32:28 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian has minimal images Sep 22 21:32:38 "console" Sep 22 21:33:19 it seems only a standalone image, but you can turn that into a flasher in the usual way by editing /boot/uEnv.txt Sep 22 21:34:21 (the procedure for that is also on that wiki page under "Flashing eMMC") Sep 22 21:35:03 note that I'm not sure whether the console image appears as usb device, but it will definitely be reachable via ethernet Sep 22 21:41:22 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Flashing_eMMC red that..!! I can't find any minimal image to download Sep 22 21:41:40 "console" Sep 22 21:41:52 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Stretch_Snapshot_console Sep 22 21:46:03 gesss that's latest debian console not X but can maybe instal lightweight desktop like jwm or what? and what about jessie 1gb Sep 22 21:46:27 you can then install anything you want, as long as it fits :) Sep 22 21:48:28 note that although they're labeled "1G", most of that is actually free space. it just means the image was premade as 1G Sep 22 21:48:47 right... so do you think jwm will it be tight Sep 22 21:48:48 jessie is obsolete Sep 22 21:48:54 I've never heard of it Sep 22 21:49:00 (of jwm) Sep 22 21:49:47 https://joewing.net/projects/jwm/ Sep 22 21:49:56 probably even lxqt would fit since there are 2G lxqt images, and those have all usual beaglebone stuff (webserver, node, etc) in addition to the GUI Sep 22 21:51:09 there are many many window managers, I'm afraid choosing one is up to you :) Sep 22 21:51:23 BBB-blank-debian-8.9-lxqt-2gb-armhf-2017-09-01-2gb.img.xz that's the one I have installed Sep 22 21:52:27 but use 99% Sep 22 21:52:38 yeah, so exactly... that shows lxqt + all the stuff that's on the iot image fits... kinda... just really not comfortably Sep 22 21:52:39 of eMMC Sep 22 21:54:11 right... It's incredible 1gb image Sep 22 21:54:31 I mean that stretch Sep 22 21:55:19 zmatt, thanks for advising... really appreciate it Sep 22 21:55:39 stretch-console should be pretty lean, although there's probably crap even on that :) Sep 22 21:56:28 I see Sep 22 21:56:41 if you pastebin a package list ( dpkg --get-selections ) of the console image I'll take a quick look to see if there's stuff that's clearly unnecessary if you want Sep 22 21:59:06 e.g. there's probably stuff for wireless networks on it, which is probably not useful to you if you have a beaglebone black rather than a black/green wireless or blue Sep 22 22:01:12 never thought and done that way before, though Sep 22 22:01:55 you mean starting with a console image and then installing a gui? Sep 22 22:03:32 ew, jwm uses xml for its config Sep 22 22:04:01 that's right... well I did with old computer booting from cds or pendrives Sep 22 22:04:43 it can be boot in old floppies too. Sep 22 22:04:52 anyway..... Sep 22 22:06:28 zmatt, thanks indeed again I will try that tomorrow... getting late over here... nite nite Sep 22 22:07:34 you can also just try "apt-get install lxqt-core" and then wait to see how much space it says is required... you can always answer no if it's more than you like :) Sep 22 22:07:46 ok, good night Sep 22 22:07:58 hang on... Sep 22 22:08:05 (on the console image) Sep 22 22:09:09 it's also worth examining the dependencies of such metapackages yourself Sep 22 22:10:02 for example lxqt-core depends (among other things) on: xfwm4 | x-window-manager Sep 22 22:10:26 Have to edit /boot/uEnv.txt with nano not used it but I will try, though enough room for that?
