**** BEGIN LOGGING AT Sat Mar 28 02:59:58 2015 Mar 28 03:00:41 and that's hardware bound? Mar 28 03:03:26 that's a restriction imposed by the lcd controller peripheral yes; one that's perfectly reasonable for its intended purpose, and it probably didn't occur to the designers that some nutcases might want to put it to creative alternative purposes Mar 28 03:04:18 but it's a pity since *not* imposing the restriction would probably not have made the hardware significantly more complicated, but would have made it much more versatile Mar 28 03:05:19 but well, c'est la vie, the peripheral is the way it is Mar 28 03:06:18 how would that restriction not have been imposed? Mar 28 03:07:49 allow setting hsync and vsync periods to zero, or more likely allow data transmission to continue during sync periods (the latter is not uncommon for video signals) Mar 28 03:08:34 have you sent this to the mailing list? The hardware designers are on it. Mar 28 03:10:10 eh, what mailing list are you referring to? I could post it on E2E, but in the unlikely event it would reach a chip designer I very much doubt they'd care Mar 28 03:12:15 (and if I'd start commenting on peripheral design, I would have better things to start with than the LCDC :P ) Mar 28 03:14:28 zmatt: you're probably right :/ Mar 28 03:20:54 although maybe I should send the beagle designers the suggestion to pull the JTAG TRSTn up rather than down to allow jbang to work without soldering (https://github.com/dutchanddutch/jbang) Mar 28 03:21:03 hi , how do I connect to the beaglebone by usb through ssh ? i need configure /etc/network/interfaces ? Mar 28 03:21:29 I know there's already one person who managed to track down a memory corruption issue using a watchpoint thanks to jbang Mar 28 03:23:27 luciano: with the default config it should just work: your computer will get an ip on the usb network interface, and you can reach the beaglebone on... ehh... I think 192.168.7.2 ? Mar 28 03:23:44 * zmatt never uses usb so isn't 100% sure about the ip Mar 28 03:25:59 zmatt, I install archlinux arm Mar 28 03:26:21 wmat: the guy had a creative workaround for the fact that linux doesn't support watchpoints on cortex-a8... he configured it anyway behind the kernel's back, so when it triggered the kernel was like "dafuq is this?!" and dumped a stack trace to the console... which was exactly what he needed :) Mar 28 03:27:07 luciano: oh, then I have no idea, sorry Mar 28 03:32:08 smurray: heh, sometimes corners are easily cut :/ Mar 28 03:34:57 watchpoints are pretty awesome to have, and it sucks hard that you can't use them on TI SoCs without an ugly hack like jbang to flip an enable-bit in a register only accessible via JTAG Mar 28 03:45:28 anyone have this cape http://www.chipsee.com/product/evm/beagle/beaglebone-black-expansion-capacitive.html ? Mar 28 03:57:45 smurray: not sure why I sent that pm to you ;?

Mar 28 11:31:42 amit_: yes, 2V won't work, needs 5V Mar 28 11:32:11 sorry Printing mistake 5V2A Mar 28 11:32:40 take a multimeter, measure the voltage Mar 28 11:33:02 board still boots if you power it over usb? Mar 28 12:41:36 sorry for delayed response, net was not working. Mar 28 12:41:54 When I connect the USB to board It works perfectly. Mar 28 13:05:52 Hello guys any clue Mar 28 13:37:46 hello! Is anybody online? Mar 28 13:42:35 wtf Mar 28 16:00:38 hellp Mar 28 16:00:41 hello Mar 28 16:01:38 can anyone help me to remove the bits that make that SD card bootable Mar 28 16:03:46 karim Mar 28 16:04:31 Fingertips333 .. just do a 'dd' command from linux on the first section of the uSD card Mar 28 16:05:20 RCN's page on eewiki.net (for BBB) gives you the command under "preparing the SD card" Mar 28 16:05:36 hello i can't connect to beaglebone black in eclipse there is a password required that i don't know Mar 28 16:05:36 hello vermit, I have tried that.... Problem is that if I have the SD card inserted then it will try to boot from it, without me pressing the button, and I want to boot only from EMMC Mar 28 16:05:56 This is what I tried : sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1024 count=1024 Mar 28 16:06:06 where mmcblk1 is the SD Mar 28 16:06:24 the SD is 8g ext 4 partition Mar 28 16:06:45 Fingertips333 .. how can you be sure its still booting from the uSD card?! Mar 28 16:07:06 Fingertips333 .. if there's no kernel or uboot there .. it cannot. Mar 28 16:07:20 sorry, I think is still trying that, because if I remove the SD card then it will boot normally Mar 28 16:07:43 with the SD card in , then it simply does not boot Mar 28 16:07:50 Fingertips333 .. alternatively you need to change the eMMC bootloaders to never try the uSD Mar 28 16:08:06 could be your problem :) Mar 28 16:08:22 Guest14250 .. default user/password for the beaglebone black is now "debian" and "temppwd" Mar 28 16:08:38 I have searched on internet how to set only emmc boot but I found nothingl, sorry I am a newbie at this, as I have the beagle since only a few days. Mar 28 16:08:41 sorry.. make that Guest92744 Mar 28 16:09:23 Fingertips333 .. suggest you wait 'til RCN himself comes in Monday-ish .. he knows most about the bootloading process afaik. Mar 28 16:10:10 Thanks for the help, I will keep trying and if I cannot make it, I will come back to you guys. Thanks again. Mar 28 16:10:54 Fingertips333 .. my assumption would be that if the uSD has no boot-associated files .. it would fall-back to the eMMC, but that doesn't seem to be the case Mar 28 16:11:15 Fingertips333 .. which version is your beagle? have you updated it ever? Mar 28 16:13:21 I have beaglebone black rev c with BeagleBoard.org Debian Image 2015-03-01 Mar 28 16:13:55 there is a box that appear when i try to connect to beaglebone called password required and it is written in it "my name@192.168.7,2 and user name which is my name and i have to write password ,i have written what u have told me but nothing happen Mar 28 16:14:05 I have update it today from sd card with sudo xz -cd bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img.xz Mar 28 16:15:15 everything is fine with it, if the sd card is removed, but I want the sd card as extra storage and backup Mar 28 16:15:58 Fingertips333 .. yup I understand .. can't figure why it doesn't ignore the uSD .. but I know there's been some trickery :) Mar 28 16:16:42 Guest92744 .. I don't believe the username is "myname" .. although I've never used eclipse .. can you ssh or use Putty to ssh to it instead? Mar 28 16:17:46 no i mean that it is "karim" myfirst name Mar 28 16:18:50 Guest92744 .. unless you've created a user on the beagle with Your name .. it won't Be there .. and you cannot log in with it. Mar 28 16:21:23 Guest92744 .. if you get a prompt similar to this: http://i0.wp.com/www.michaelhleonard.com/wp-content/uploads/2013/07/Screen-Shot-2013-07-12-at-1.44.56-PM.png .. I suggest you change the 'user' to 'debian'/'root' Mar 28 16:28:06 Thats work fine ,thanks veremit Mar 28 16:28:22 :) Mar 28 16:43:16 hi i didn't any find the tmp folder under my beaglebone ,sftpfiles,My Home ?! Mar 28 16:46:54 Guest38139 .. what are you looking for? Mar 28 16:47:51 i want to copy the c project i have done to beagle bone folder called tmp/tmp/ Mar 28 16:48:43 tmp is usually located in the / top-level root Mar 28 16:49:13 ie. "cd /tmp" should take you there from a prompt Mar 28 16:49:43 but beware that /tmp is usually wiped every boot Mar 28 16:56:08 Thanks :) Mar 28 17:22:45 np Mar 28 18:02:05 hmz, annoying that the am335x datasheet doesn't spec the "micro edge positioning" step size of the eHRPWM modules Mar 28 18:02:38 (even more annoying they didn't include some convenient way to calibrate it, considering it is apparently somewhat dependent on voltage and temperature) Mar 28 19:36:57 Really voltage and temperature dependant? hmmm Mar 28 20:58:18 new to BBB do not see accessories on screen after bootup Mar 28 23:40:38 how do i set up networking to network out of my bblack Mar 28 23:40:55 plug a network cable in? Mar 28 23:42:25 i have a terminal session working Mar 28 23:45:27 via usb per-chance? Mar 29 00:11:10 veremit: yes usb Mar 29 00:11:38 and you're using windows or linux on your pc/tablet/door-stop/etc ? **** ENDING LOGGING AT Sun Mar 29 02:59:58 2015
