**** BEGIN LOGGING AT Wed Mar 02 02:59:59 2016 Mar 02 03:57:39 yates: many boot modes have uart in the boot device order, including both boot orders used by the BBB (the default one and the one when SD button is held) Mar 02 03:58:26 specifically the default sysboot 0-4 is 0b11100 which corresponds to boot device order { eMMC, uSD, uart, usb } Mar 02 03:59:04 holding the SD button during power up makes it 0b11000 which is { spi, uSD, usb, uart } Mar 02 03:59:23 you can find all defined boot orders on the Boot tab of my spreadsheet Mar 02 03:59:42 (and the purpose of the remaining sysboot pins) Mar 02 04:58:41 Hi, i am using Linux beaglebone 3.8.13-bone70 on beaglebone black. I am using RTC DS1307. It gets detected. But the problem is somehow the system time is getting written on rtc? Mar 02 05:15:47 Hi, i am using Linux beaglebone 3.8.13-bone70 on beaglebone black. I am using RTC DS1307. It gets detected. But the problem is somehow the system time is getting written on rtc? Mar 02 05:16:01 It would be great if someone could help Mar 02 05:26:46 abhi__: there are various mechanisms that may be responsible for such synchronization Mar 02 05:27:04 it makes sense that if an RTC is detected, it automatically gets used as RTC Mar 02 05:27:51 undoubtedly you can also prevent this, but the details depend a bit on who's responsible.... I don't the kernel does this on its own intiative Mar 02 05:28:57 (btw, don't repeat your question if you don't get an answer in 15 minutes... people may be in another timezone, busy, asleep, etc. It can take a bit before someone notices and answers) Mar 02 05:31:54 is the am335x internal RTC also enabled? what are the device names of the two RTCs? (i.e. /dev/rtc0 /dev/rtc1 ?) Mar 02 06:24:22 @zmatt .Sorry to post two times. /dev/rtc1 is enabled. Mar 02 07:03:21 v Mar 02 08:38:49 hello Mar 02 12:36:01 hello, I have a question, is there any level shifter circuit out there? for UA741? because mine is drifting from 3V+ +-3V to +-1.5V Mar 02 12:38:26 ? Mar 02 13:52:38 Digikey is out of stock. When is the new production scheduled to ship to the distributors? Mar 02 13:53:09 Any idea? Mar 02 13:54:08 at any time Mar 02 13:54:27 dont wait for stock, order and you will get once they are shipped Mar 02 13:54:40 its like the queue for a new iphone:) Mar 02 13:57:49 also I'd recommend to order the Embest version. The CCo version tends to have a bit of variance in the supply... Mar 02 14:09:35 thanks! Interesting about the embest version. I would have though that the CCo would have more consistency... Mar 02 14:11:57 Just to be sure: Embest == Seeed ? Mar 02 14:14:20 question to the group: how would you perform development (modifying dtbs, loading and building custom applications, etc.) on a bbb without sdcard or ethernet, but with cellular modem and uart0 serial port? Mar 02 14:14:58 i should add, using a full linux system Mar 02 14:16:19 ssh into BBB over cell modem? Mar 02 14:17:54 not directly bbb related, but is a gnu dialect prone to change? i.e. C99 is a fixed standard, where gnu99 is the GNU dialect of C99. Will gnu99 ever change or is it similiar fixed like C99? Mar 02 14:26:58 I agree with av500: ssh/sftp through serial and/or cellular (modem). Just ensure you also have a local beagle to test on -- lest a deployment necessitates a site visit (to reset) Mar 02 14:27:28 also -- note your constraint of 4gb - budget accordingly. Mar 02 14:34:23 hi philenotfound. It seems that change unlikely, but compliance not complete ( https://gcc.gnu.org/c99status.html ). It seems there were changes in many sub-versions -- evn to the most recent. Mar 02 14:35:24 So, c99 is fixed; and g99 is slowly approaching complete compliance with this. Mar 02 14:35:40 (ie will continue to change untill 100% -- ideally) Mar 02 14:35:57 Thank yo all very much.. need to go now. Mar 02 14:36:00 byeeee Mar 02 14:50:49 so, with the debian kernel on the beagleboard-x15, the fan kicks on and off multiple times per minute... are there some values that need tweaking in mainline to allow the fan to either stay on, or stay on for a minimum amount of time or something? Mar 02 14:52:06 stop using the "hairdryer" release ;) Mar 02 14:53:08 at least a hairdryer stays on when you flip the switch to the on position Mar 02 14:53:26 heh Mar 02 15:02:58 av500: not possible. no publicly-accessible ip address. Mar 02 15:03:07 and it's dynamic Mar 02 15:04:30 so reverse Mar 02 15:04:40 make the BBB login to your server Mar 02 15:04:46 periodically Mar 02 15:04:55 but why exactly do such pain? Mar 02 15:05:08 why not develop locally and find just a way to "deploy" updates Mar 02 15:08:05 av500: what do you mean by "develop locally?" you mean on a board with eth and sdcard? Mar 02 15:09:39 yes Mar 02 15:22:23 hello everyone, i need some assistance connecting a 16x2 lcd display to the beagleboard xm. my components are the following: http://imgur.com/a/JPlg1 top image, back side of lcd. 2nd and 3rd beagleboard xm expansion connectors and 4th img are the gpio cables. i need to write a kernel module to display a message on the lcd. how do i connect them? Mar 02 15:22:28 av500: this is a design approach question. we are trying to decide what to include on our second-round board design, i.e., whether or not to include sdcard/eth. any such "deployment" solution has yet to be developed and tested. thus my questions. Mar 02 15:23:02 dsky: did you try to google that? Mar 02 15:23:11 you are not the first to connect a char LCD to a BBB Mar 02 15:24:42 av500: actually, i'm know what i would do (just put the eth/sdcard on), but it's not my project. i am trying to convince our project manager we need to include these until the deployment solution is developed. and i'm trying to find out if i'm missing something, i.e., if doign development without these wouldn't be so bad. it seems to me it'd be like driving blind.. Mar 02 15:25:21 yates: so you plan to do all development by uploading over serial? Mar 02 15:25:51 i wouldn't plan such a thing, but the project manager in his infinite wisdom seems to want us to work that way, yes. Mar 02 15:25:53 yes, i googled it. all examples are using a white board onto which the lcd is soldered Mar 02 15:26:01 dsky: no Mar 02 15:26:07 thats the LCD cape Mar 02 15:26:10 you dont want that Mar 02 15:26:23 https://www.google.com/search?q=beaglebone+character+lcd Mar 02 15:26:46 https://www.google.com/search?q=beaglebone+HD44780 Mar 02 15:28:20 yates: you can still bring out a few pads on the PCB to hookup an SDIO Mar 02 15:28:36 am i justified in suggesting strongly we keep the eth/sdcard until a deployment solution is complete? Mar 02 15:28:42 so you only need to use the serial to do "cp ...." Mar 02 15:28:51 sdcard at least Mar 02 15:29:15 but of course an NFS mounted rootfs is nice for dev work too Mar 02 15:29:20 yes, but it seems he doesn't even want to do that. he has all sorts of paranoid thoughts on the sdcard. Mar 02 15:29:30 av500: true. Mar 02 15:29:45 have usb host? Mar 02 15:29:50 can do ush eth too Mar 02 15:30:22 for one, our schematic layout dude had the mechanical orientation reversed (on the initial board) which caused a lot of heartache. Mar 02 15:30:41 av500, thank you for taking the time to google, but none of these help me :/ none of the examples use the setup i do, i only have 6 gpio cables to work with and i cant find out how to connect them Mar 02 15:30:45 thats what tiny wires are for Mar 02 15:30:52 av500: no, we castrated the usb to be a direct connection to our one usb device: a telit le910 cell modem Mar 02 15:30:58 dsky: yes, HD44780 in 4bit mode Mar 02 15:31:13 direct on-board connection, i.e. Mar 02 15:31:25 dsky: the missing 4 pins on your LCD are bit4-7 Mar 02 15:31:47 dsky: trust me Mar 02 15:31:51 you are not the first Mar 02 15:33:17 if board space is not an issue, and component cost is not an issue (at least for a few prototype boards), can you see anything wrong with putting the connections for sdcard and eth on and simply nopopping for production? Mar 02 15:33:45 i can't. and it would speed development big-time, imo. Mar 02 15:35:21 what is your opinion, av500? Mar 02 15:37:04 or anyone else, for that matter? Mar 02 15:38:30 the question still remains, how would you get the initial code into the eMMC? i'm assuming either a) somehow program it (factory prgramming?) before placing it on the board, or b) (for prototypes) using the jtag Mar 02 15:39:00 if anyone has experience with this, i'd love to hear their approach Mar 02 15:40:27 yates: Are you talking about a BBB without Ethernet and sdcard? Then how to program eMMC? Mar 02 15:42:37 yates: According to http://ahsoftware.de/Beaglebone_Black_Boot_explained.svg you can also boot over USB0 or UART0 so you could use those to program the eMMC first time around. Mar 02 15:43:43 jtag would also be viable, you can upload code via jtag to the cpu to program the eMMC. OR bit bash the eMMC pins with boundary scan if the jtag supports that. Mar 02 16:00:36 <_av500_> yates: nobody factory programs EMMC Mar 02 16:01:00 <_av500_> at least not in consumer Mar 02 16:01:14 <_av500_> sure for industrial somebody will charhe you gladly Mar 02 16:01:17 <_av500_> charge* Mar 02 16:02:33 <_av500_> yates: you can serial boot Mar 02 16:02:37 <_av500_> for bringup Mar 02 16:02:51 <_av500_> and you can run serial at > 1Mbit Mar 02 16:03:10 <_av500_> or USB boot Mar 02 17:25:10 ok, these methods are possible, but are they practical for software that is not stable, e.g., updates possibly several times a day? Mar 02 17:25:35 you could run ppp over the serial, right? Mar 02 17:25:57 and essentially establish a network connection over serial. may be slow, but it's possible, right? Mar 02 17:27:35 i'm trying to argue FOR something i don't want, just to see if it's truly plausible. Mar 02 17:27:53 i say screw all this and put the damn components/interfaces on the board for now. Mar 02 17:28:23 as i asked previous, why not? (if board space, component costs, etc., aren't issues, which they are not) Mar 02 17:29:57 nothing prevents you from disconnecting the network, pulling the eth cable off, and testing the stand-alone deployment implementation. so you get everything you need: tools for development, and atest bed for deployment. Mar 02 17:30:23 s/pulling the eth cable off/pulling the sdcard off/ Mar 02 17:32:09 hello? Mar 02 17:32:14 right? wrong? somewhere in between? Mar 02 17:36:36 there is at least one potential gotcha: removing the eth PHY will leave the interface bus dangling and i don't know what the driver will do with that. hopefully it's a graceful "um, i don't see a network, closing down" thing. Mar 02 17:54:36 hi! can anyone tell me how to troubleshoot the flashing process of a BBB? i read the getting started guide and put a flasher image onto my SD card. i pressed the boot button while powering up the device (with sufficient power). the user LEDs flash, but i think it´s not the "magical" pattern in which they should blink Mar 02 17:55:12 also, after less than a minute, the user leds change to the "heartbeat" blinky on the first user led... Mar 02 17:55:41 obviously,in such a short period of time, the internal emmc surely was not written Mar 02 17:55:49 any ideas on how to proceed? Mar 02 17:56:47 i currently don´t have a micro HDMI adapter which is why i cannot watch the graphical output Mar 02 17:57:19 in any case, connecting to the BBB´s start page via USB does not work, it leads me to a blank apache site Mar 02 18:03:18 help me plz anyone Mar 02 18:04:29 My beaglebone is not showing up on my TV, I have plugged in the micro hdmi -> hdmi, but it just doesn't load up at all Mar 02 18:06:06 any help at all would be great ? Mar 02 18:08:37 helpmeplz: first of all: https://workaround.org/getting-help-on-irc/ Mar 02 18:09:09 helpmeplz: what image are you running? Have you ever edited the uEnv.txt file to disable HDMI? Mar 02 18:09:56 Honestly, I haven't actually done anything I have just tried to plug it into my TV and it is not displaying anything, there is a flashing blue light on it Mar 02 18:10:50 helpmeplz: have you followed the getting started steps? http://beagleboard.org/support/bone101 Mar 02 18:11:09 step one being flashing the latest image Mar 02 18:12:37 I believe so, I haven't plugged it into my TV for probably about a few months, but I remember the last time I used it, it came up on the TV saying "Login: " Mar 02 18:13:37 if you don't have anything important on it I'd recommend starting with flashing an image from here: http://beagleboard.org/latest-images Mar 02 18:14:46 can i do this without an sd card? Mar 02 18:15:06 helpmeplz: that it read "Login:" means you had some significant success. you may not have the right linux .img version that displays on the hdmi, i.e., just a console version. Mar 02 18:15:35 there is a usb flasher Mar 02 18:15:42 helpmeplz: go buy an sdcard. walmart had a sale recently for 4GB sdcards for USD2.50 each. Mar 02 18:16:16 I also always just boot from SD cards instead of flashing the eMMC Mar 02 18:16:25 that way it's easier to change images Mar 02 18:17:48 you're welcome. Mar 02 18:17:58 hi there sorry i dc Mar 02 18:18:43 is it possible to do it without an sd card, I only want 1 version of linux Mar 02 18:19:48 its just i want it to work, im not sure if my hdmi is broken it doesn't display anymore Mar 02 18:19:51 yeah, where's that USB flasher? I can never find it... Mar 02 18:21:12 BBB eMMC flasher? Mar 02 18:22:53 yeah Mar 02 18:23:53 and how would i put that on my beaglebone black? Mar 02 18:24:47 that runs on your computer and flashes the eMMC over USB Mar 02 18:25:20 but didn't your beaglebone come with an SD card? Mar 02 23:24:49 Hey ! I need gnu/stubs-soft.h file. What package should i install ? uname -a : Linux beaglebone 4.1.17-ti-rt-r48 #1 SMP PREEMPT RT Fri Feb 12 23:46:00 UTC 2016 armv7l GNU/Linux Mar 02 23:33:04 ZeekHuge: are you sure you need stubs-soft? that's only valid for software floating point systems, which doesn't apply to the BBB Mar 02 23:34:16 I see a /usr/include/arm-linux-gnueabihf/gnu/stubs.h in libc6-dev Mar 02 23:38:01 ddrown, stubs.h and stubs-hard.h are already present on my BBB.

Mar 02 23:50:40 filt3r, that flag is for clpru . right ? Mar 02 23:52:42 the flag is for the gcc compiler Mar 02 23:54:35 I am trying to build the PRU-framework. and the current Makefile is this : http://paste.debian.net/411188/ Mar 03 00:19:31 i need help flashing my BBB **** ENDING LOGGING AT Thu Mar 03 02:59:58 2016
