**** BEGIN LOGGING AT Mon Jul 11 02:59:58 2016 Jul 11 08:09:26 hello Jul 11 08:10:25 * phschafft waves. Jul 11 08:14:23 does exist this cape? http://elinux.org/Beagleboard:BeagleBone_8_Port_1-Wire .. Jul 11 08:15:43 when i click on the links i got the message site can't be reached Jul 11 08:41:29 the page works fine for me. maybe some networking problem on your side? Jul 11 08:44:01 I got a BBB. When I connect it via USB I got the mass storage device (can mount, actually works) and a ethernet interface. But the board doesn't seem to answer DHCP or other requests. Jul 11 08:46:08 another BBG worked just a few min ago. Jul 11 08:46:18 Any ideas? Jul 11 08:46:24 phschafft: IIRC there is some mechanism telling the host computer to assign 192.168.7.1/24 (not sure if dhcp or sth else) also welcome to the beagle community ;) Jul 11 08:46:35 phschafft: foremost, which images are you running :) Jul 11 08:47:04 * phschafft waves. Jul 11 08:47:12 nice to meet you in here as well. Jul 11 08:47:38 tbr: on BBG it was DHCP. but even if I assign the IP manually it doesn't seem to work. Jul 11 08:48:05 btw: failure to acquire IP is a known problem that seems to happen randomly, especially on windows. Jul 11 08:48:21 right, so, what OS is it running? Jul 11 08:48:36 there should be a ttyACM device if you don't have UART access Jul 11 08:49:39 I don't know. Just got th device from my (kind of tutor). Jul 11 08:51:20 phschafft: you can access http://by-innovation.com/1-Wire-BeagleBone-Cape ?? Jul 11 08:51:23 is there anything on those devices that you still need? or are you going to set them up to your liking? Jul 11 08:52:13 the wiki page works for me but not the producer page Jul 11 08:54:20 phschafft: the best way is to plug a 3.3V or 5V UART adapter into the debug port of the board. The pin layout is "FTDI" (that's how it's commonly referred to) Jul 11 08:55:44 tbr: I was told that I can erase it. Jul 11 08:56:07 I thought about downloading a new image and try to boot it. Jul 11 08:56:32 yes, I'd nuke the eMMC contents from orbit in that case Jul 11 08:56:51 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Image_Testing_Snapshots Jul 11 08:57:08 double-check which revision the BBB is Jul 11 08:57:25 if it's revA or revB, then you can only flash 2GB images to the eMMC Jul 11 08:58:07 unless you need HDMI output and Xorg, I'd recommend an "IoT" image Jul 11 08:59:03 all images will boot fine from SD if it's at least 4GB in size Jul 11 09:00:00 ok. Jul 11 09:00:14 waiting for the download to finish. Jul 11 09:00:58 recommended kernel version will depend on your use case Jul 11 09:00:59 is there any way to correctly power down the board with only physical access? Jul 11 09:01:23 I don't think so, unless someone got around to make the power button work properly Jul 11 09:04:50 I was told the board doesn't like being switched off without shutdown. Jul 11 09:04:54 that is why I asked. Jul 11 09:05:21 it's 'just' the filesystem that gets yanked Jul 11 09:06:22 btw: if you are attaching ANYTHING to the IO pins of the SoC, then that MUST be off while the board is off. Feeding any kind of voltage back to the board is a very good way to kill the SoC Jul 11 09:06:35 that I don't care for. But he said something about the 'power controler IC'. But it sounds a bit like the myths you always got for those SoC-boards. Jul 11 09:06:53 ah, there is some sort of PMIC problem Jul 11 09:07:14 but it's not well understood (last time I checked) Jul 11 09:07:19 hm? Jul 11 09:07:24 zmatt might know more Jul 11 09:07:44 but anyway, I hadly have any other options it seems. Jul 11 09:10:56 phschafft: http://elinux.org/Beagleboard:BeagleBoneBlack#Improper_Power_Down....All_Revisions Jul 11 09:12:39 this implies, that the power button should work Jul 11 09:15:28 it should, but it doesn't. hm... Jul 11 09:18:56 no UART cable at hand? Jul 11 09:19:05 ttyACM0 not showing up? Jul 11 09:21:07 or you could write a good image to SD, insert that, press reset while holding down the button next to the SD slot. that would make it reboot into the SD image :) Jul 11 09:24:39 no UART here. Jul 11 09:24:43 so I try the image. Jul 11 09:25:07 I need a fresh one anyway. :) Jul 11 09:59:04 does exist some other 1-wire capes? Jul 11 09:59:48 IIRC 1-wire is just adding one resistor and optionally a transistor Jul 11 10:20:30 HI Jul 11 10:20:59 Anyone from Beaglebon black team Jul 11 10:25:07 tbr: i know but I like the "click" sound when ein plugin in a RJ11/RJ45 cable ;) .. ok serious: I know it is easier but I want to create (build?) a server-room monitoring enviroment based on 1-wire sensors (temp, humidity, smoke and leckage/water sensor) Jul 11 10:25:40 i will need also a 19" rack for it Jul 11 10:27:53 sounds like you have your work cut out then :) Jul 11 13:32:01 Hi Jul 11 13:32:37 is it possible to port free rtos on beaglebone black? Jul 11 13:34:38 is it possible to port free rtos on beagle bone black? Jul 11 13:37:50 yes Jul 11 13:42:53 tbr: hmmwhat? Jul 11 13:44:09 phschafft: pressing the power button (short) when the system on sends some sort of event, and at least on the default gui builds this makes the system shut down Jul 11 13:44:40 I'm not really sure which piece of userspace logic is responsible Jul 11 13:45:26 zmatt: do you know if the problem with yanking out power vs shutting down was understood in the end? (leading to a bad shutdown sequence from pmic and killing the soc) Jul 11 13:46:18 in theory, although I don't know how soon it becomes a problem in practice Jul 11 13:46:46 eMMC also doesn't appreciate it Jul 11 13:46:48 ah, so it's a cumulative degradation? Jul 11 13:47:44 maybe, depends on what kind of stress occurs, which itself may depend on random board variability and connected external hw Jul 11 13:48:05 s/board/components/ Jul 11 13:48:33 *nod* Jul 11 13:49:42 and consensus seems to be that if you abruptly cut power to eMMC (especially those with multilevel NAND, which is probably all nowadays), and do it sufficiently often then eventually you'll end up with a corrupted filesystem Jul 11 13:51:39 Corrupted sounds bad. Jul 11 14:00:17 Research also indicates this is unavoidable, in that I haven't found a PMIC interrupt or anything that would facilitate "finish this block and stop before we die" functionality. Jul 11 14:32:49 I'm wondering why the NodeJS is still at rev 0.12 for BBB/BBG under the current Debian builds. Is there a plan to go to v4 or v6? Or a reason that won't work? Jul 11 14:33:08 we use v6 without problem Jul 11 14:34:10 Ok, that's great. So why doesn't apt-get bring in a newer version? Is it just that rcn hasn't gone there yet? Jul 11 14:35:35 echo deb https://deb.nodesource.com/node_6.x jessie main >/etc/apt/sources.list.d/nodesource.list Jul 11 14:35:44 then apt-get update and try again Jul 11 14:36:48 and debian is always ancient stuff... nodejs goes way too fast for debian Jul 11 14:37:20 debian unstable has 4.4.7, and there's a 6.0.0 package in experimental, lol Jul 11 14:39:15 zmatt: Ok, great. I'll try that. As always, many thanks. Jul 11 14:46:51 Ragnorok: maybe a solution would be to have a cap that is just for buffering the lowlevel shutdown. filesystem could of cause still be corrupted this way. Jul 11 14:47:41 We have an option for battery. I think the simple route is make that non-optional. (grin) Jul 11 14:52:45 haha. Jul 11 15:03:26 zmatt: that worked for installing nodejs v6. npm install serialport then failed for me. Any experience on that front? Jul 11 15:15:48 nope sorry, I dislike js and avoid it when possible Jul 11 15:18:02 ok, thanks. I'll see what I can figure out... Jul 11 16:12:40 Hi guys, I have a question: how do I compile a devicetree for the 4.4.9 kernel, so I do not have errors while compiling or booting? I would like to access some gpios from the prus Jul 11 16:38:36 I've never gotten PRUs to work without using the old school uio_pruss, and the simplest route to that is use a *bone kernel that has it rolled in. Jul 11 17:51:58 Hello, I have my BBB hooked up to my desktop with the mini-USB. I am able to ssh into the board. I am trying to attach a Arduino to the USB-A. LSusb command shows the Arduino attached, but how do I find out which port it is attached to? Jul 11 17:53:18 * tbr is not familiar with arduino, does it expose itself as a serial device? Jul 11 17:55:00 I believe so. It is able to receive serial commands Jul 11 17:56:34 I am pretty inexperienced so some things I don't understand, but I have read enough to be dangerous:) Jul 11 17:56:36 then it should show up as a character device in /dev/tty*, probably /dev/ttyACM0 or /dev/ttyUSB0 or such Jul 11 17:57:41 How do I search that? My desktop and BBB are running Ubuntu Jul 11 17:58:16 it should show up the same as on the desktop. have you used it on the desktop? Jul 11 17:58:35 for most intents and purposes the BBB is "just another Linux system" Jul 11 18:01:20 I will confirm. When I get back to the device. Thank you for help. I will bbl Jul 11 20:35:46 Hi I am new to beaglebone. I am writing my code on cloud9 and its working on the beaglebone but as soon as I recycle power the code on the beaglebone goes a way.
