**** BEGIN LOGGING AT Thu Apr 16 02:59:59 2015 Apr 16 03:47:03 <_2_gavia> hey Apr 16 09:17:05 hi, can i have sgx on oficcial beaglebone black kernel 3.8.13. or have to compile ti-kernel to have 3d accelerator? Apr 16 09:58:13 Question about pinmuxing on BBB: is it possible to change I2C2 pins from P9_19 and P9_20 to P9_21 and P9_22 with overlays, or do I have to edit the default dtb? Apr 16 11:56:57 Am trying to update my BBB with the latest image file provided by the website but it is taking 6-7 hrs and still am unable to update it. When I tried to connect it using ssh root@192.168.7.2 it just hangs for hours... Can anybody help me please??? Apr 16 12:24:26 Are you monitoring either the serial console or the hdmi out during the update? Apr 16 12:48:38 hi, how can i generate uInitrd for a running kernel? update-initramfs -c -k $(uname -r) just creates initrd.img Apr 16 14:13:09 I am using baegleboard xm , when we turn ON the power ,its show a prompt for some sec ,after that our screen get Blank Apr 16 14:44:22 hello, i have a little problem with my beaglebone black with debian. I wrote a js server and website which constantly reads out the value of my rotary encoder and updates the value on my website. The whole thing works without a problem.But now i'm trying to access the site within my home net.I can see the site but it doesnt update the value. Apr 16 14:46:12 if i access 9cloud, the console shows and updates the values. I don't know where to look. Could it be a network problem? Or could it be a thing with javascript? Apr 16 15:05:38 Yesterday, I asked you about a project which can use a LCD touch display and 1 LCD HMDI display both of 7" at the same time (duplicate or different image) with BBB, the anwser was no, The BBB don't have video output for two displays at the same time. Apr 16 15:06:48 I have another question, Can the BB-xM do that? Apr 16 15:09:03 anyone? Apr 16 15:20:48 fer, I think it can if they are duplicates, rather than separate screen... but I'm not positive on that Apr 16 15:26:51 thk Thurgood, for your response Apr 16 15:28:42 anyone with a coment, I need to be sure, Apr 16 16:00:39 w Apr 16 16:03:12 jkridner: saw that you were able to fix the timing race rcn-ee located. thank you. what did you have to do? Apr 16 18:32:48 jkridner: fwiw, if you responded, i accidently had the channel muted on my end. Apr 16 18:45:15 he hasn't responded anyway Apr 16 19:19:09 just got my serial console cable in the mail Apr 16 19:19:40 am i correct in thinking that i can use it to power the BBB Apr 16 19:26:13 internet says not to plug in the red jumper because it will fry the BBB Apr 16 19:31:09 You can't use it to power a BBB. An FTDI cable will only supply 75 mA on the VCC wire Apr 16 19:32:49 I have it plugged in and haven't fried by beaglebone, for what it's worth. But try it without first. You should only need RXD, TXD, and GND Apr 16 19:33:54 limbrik: seems to be working fine without VCC plugged in Apr 16 19:34:12 limbrik: having trouble getting my terminal to return legible characters though Apr 16 19:34:31 l4cross: Did you set the baud rate to 115200? Apr 16 19:35:23 limbrik: i think that may be the issue. using os x and i set that in the system config but didn't pass it as an arg at the command line Apr 16 19:37:46 limbrik: yup, that was the issue. thanks. Apr 16 19:38:29 l4cr0ss: cool! no problem Apr 16 20:43:15 l4cr0ss: from terminal I usually use "screen /dev/tty.usbserial-FT##### 115200" Apr 16 20:51:56 moto-timo: the final argument is what fixed it for me. my /dev/{id} is a little different though. Apr 16 20:52:19 moto-timo: do you have an issue using ctrl-a followed by pg-up/pg-dn on your mac? Apr 16 20:57:38 l4cr0ss .. its a screen issue .. use the screen scrollback commands Apr 16 20:57:47 oh wait .. maybe you are :p Apr 16 20:59:48 l4cr0ss: I usually use the Terminal menus. I think command-down is page down, for instance. Apr 16 21:00:10 l4cr0ss: but it is very weird sometimes (like you are experiencing) Apr 16 21:00:31 * moto-timo is away from Mac Apr 16 23:21:34 trashguy and anyone else who may have seen my earlier statement regarding powering the BBB via the expansion headers: I has come to my recent attention that the pins were mislabeled in my overview, the correct pins are 5 and 6 of P9, _not_ pins 7/8 Apr 16 23:21:41 *it has Apr 16 23:22:38 zmatt.. I think you can meter the pins back to the barrel connector, no? Apr 16 23:22:48 the *good pins Apr 16 23:23:02 iirc its the top set, as you describe Apr 16 23:23:13 pins 5/6 are directly connected to the DC input set yes Apr 16 23:23:16 labeled vdd_5v Apr 16 23:23:35 sys_5v is the output of the pmic Apr 16 23:23:40 yikes Apr 16 23:23:59 yeah we created a daughter board .. but used the top set Apr 16 23:24:05 that's 5/6 Apr 16 23:24:17 yup Apr 16 23:25:14 higher efficiency would be obtained by using the battery pins, but they're kind of annoying to connect to Apr 16 23:25:29 you think? Apr 16 23:25:37 pmic ds says so Apr 16 23:25:44 why's that then? Apr 16 23:27:05 internal resistance of the dc/usb power paths is higher than the one of the battery, apparently due to extra protection stuff because they come from the scary outside world while the battery input is considered more trustworthy Apr 16 23:27:48 I suppose its less likely to reverse-polarise .. unless some muppet conects it backwards lol Apr 16 23:28:30 I'm not sure the pmic protects against reverse-polarization, but it does have overvoltage protection on the dc input which it lacks on the battery Apr 16 23:28:55 which makes sense, since batteries rarely spontaneously produce an excessively high voltage :P Apr 16 23:28:57 mhmm Apr 16 23:29:52 (for further details, see the tps65217 datasheet of course) Apr 16 23:30:13 yus Apr 16 23:30:25 usb ain't gonna go 'high' either .. Apr 16 23:30:39 or certainly Shouldn't . lol Apr 16 23:31:32 indeed, though the pmic protects against it anyway (protection kicks in around 6V and is rated to withstand 20V max) Apr 16 23:31:42 no polarity reversal protection btw Apr 16 23:31:47 heh Apr 16 23:31:52 nothing a diode wouldn't cope with :D Apr 16 23:31:58 esp a schottky Apr 16 23:32:42 still, even a small voltage drop is going to be a non-negligible power loss under these circumstances Apr 16 23:34:13 it all adds up Apr 16 23:35:10 I wonder what exactly the market is for the high-temperature omap-L137 ... and what kind of PCB is okay with 175 °C .. Apr 16 23:35:52 hrm .. fr4 will delaminate at that temp I'm sure .. Apr 16 23:36:05 not initially .. but eventually Apr 16 23:36:37 since all pcb's stand 280'C for reflow Apr 16 23:39:02 also I think the first time I've seen KGD ("known good die") available as packaging option... with (x,y) coordinates in the pin listing Apr 16 23:39:23 wow! Apr 16 23:42:59 ( http://www.ti.com/lit/ds/sprs677b/sprs677b.pdf page 21 ) Apr 16 23:47:10 I guess the PTP package is TI's suggestion for thermal management, and KGD is the "go figure it out yourself" solution Apr 16 23:52:57 * zmatt wonders why there's a tangerine with an electrolytic capacitor stuck into it in the office kitchen Apr 16 23:58:44 Someone had a bad trip and that was the result? Apr 16 23:59:33 ... in the office? I can think of better places to trip Apr 16 23:59:47 :D Apr 17 00:00:02 (like, pretty much anywhere) Apr 17 00:02:06 (HAR2009 by night was definitely a good one... http://photos.blinkenarea.org/index.php/HAR2009/HAR2009-night-m1-21 ) **** ENDING LOGGING AT Fri Apr 17 02:59:58 2015
