**** BEGIN LOGGING AT Fri May 09 03:00:01 2014 **** BEGIN LOGGING AT Fri May 09 08:32:12 2014 May 09 08:54:28 hi quick question, how to enable spi bus in u-boot for beagleboard XM (any docs? links?) May 09 09:00:53 has anyone enabled SPI bus in u-boot? May 09 09:13:55 I have Angstrom Distribution (BeagleBone, BeagleBone Black - 4GB SD) 2013-06-20 which is Runs on BeagleBone Black as well without flashing the eMMC May 09 09:13:55 BBB works fine when it is booting from sd card With kernel version Linux beaglebone 3.8.13 May 09 09:13:55 Now I have compiled beagleboard linux kernel and built uImage using following steps. May 09 09:13:55 git clone git://github.com/beagleboard/kernel.git && cd kernel May 09 09:13:55 git checkout 3.8 May 09 09:13:56 ./patch.sh May 09 09:13:58 downloaded am335x-pm-firmware.bin from http://arago-project.org/git/projects/?p=am33x-cm3.git;a=tree;f=bin May 09 09:14:00 copy it to kernel/firmware May 09 09:14:02 cp bin-am335x-pm-firmware.bin /home/sachin/greenzone/source/kernel/kernel/firmware/am335x-pm-firmware.bin May 09 09:14:04 cd kernel May 09 09:14:06 cp ../configs/beaglebone .config May 09 09:14:08 sudo apt-get install gcc-arm-linux-gnueabi May 09 09:14:10 source/kernel/kernel$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage dtbs May 09 09:14:12 source/kernel/kernel$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage-dtb.am335x-boneblack May 09 09:14:14 If I take sd card out and on my local machine If I copy uImage which I have built from local machine to sd card which at /rootfs/boot/uImage-3.8.13 May 09 09:14:19 and then insert sd card with new uImage, will it boot. will it work. May 09 09:15:32 what in the world keeps you from "just trying"? May 09 09:15:51 and really no need to copypaste us all the steps May 09 09:16:31 I have tried but it doesnt boot. But I just wanted to verify whether this is valid or I am doing something wrong fundamentally. May 09 09:16:53 then find out "why it doesn't work" May 09 09:17:13 you can also manually load an uImage from the card, u-boot has a command line May 09 09:17:29 do not always expect us to do your basic research work May 09 09:18:10 Yes sure. But any direction to find for "why it doesn't work" May 09 09:19:31 find out what u-boot does, verify the steps, etc. May 09 09:20:40 Thanks, I will search. but the way I am trying is ok or still not in good direction. May 09 09:22:23 the idea to replace the kernel on the sd card is basically correct May 09 09:22:54 Thanks Thanks...Cool. now I will check how to build uImage which will work as replacement. May 09 09:29:36 any tips with enabling SPI in u-boot? May 09 09:38:44 how about getting CONFIG_CMD_SPI working on beagle? May 09 09:40:37 waazu: what about asking concise questions instead or repeating very generic ones? May 09 09:40:57 waazu: ahve you tried? if not, why not? if yes, what does not work? error messages? etc.pp. May 09 09:45:12 i am a newbie so have been trying to understand how to make changes in u-boot May 09 09:45:30 i am working with a beagle board, and trying enable the SPI bus in u-boot May 09 09:45:51 plan to test it with a scope and analyzer May 09 09:45:56 i am currently learning this May 09 09:46:28 one thing is to get the SPI command in the u-boot shell working for beagleboard May 09 09:46:57 well then what happens if you enable CONFIG_CMD_SPI? May 09 09:48:43 havent gotten it enabled May 09 09:48:55 thanks for your help, thats what i am trying to do first May 09 09:49:02 *sigh* May 09 09:49:20 "i'd rather ask 10 times first before trying the obvious myself" May 09 09:50:31 hi May 09 10:15:50 BBB booted using I have built kernel uImage, previous I was using (uImage-dtb.am335x-boneblack -> renaming to uImage-3.8.13) now I used uImage by renaming uImage-3.8.13 May 09 10:16:00 Thanks LetoThe2nd May 09 10:20:27 I can only ssh to board, Can I change uImage when I am logged in and reboot device to load new kernel. May 09 15:12:39 Looking for tipps how to make cron work. Cron seems not execute what i put into /etc/crontab, dont know its reason. May 09 15:13:25 use proper formatting? May 09 15:13:51 # m h dom mon dow user command * * * * * root echo 11 >/etc/andor_output& May 09 15:13:59 ops, its a bit ugly, sec May 09 15:14:16 so there is a format in crontab: # m h dom mon dow user command May 09 15:14:30 and did a line into: * * * * * root echo 11 >/etc/andor_output& May 09 15:14:38 it should simple make a new file May 09 15:14:52 it doesnt May 09 15:25:34 fount a file like crontab /var/spool/cron/root - also not works, never executes command inside May 09 15:28:21 you need to use the crontab command May 09 15:28:24 and not just edit the files May 09 15:28:30 editing the files will not trigger the daemon to re-read them May 09 15:28:44 also May 09 15:28:52 specify the full path to the program you're executing May 09 15:28:59 e.g. /bin/echo May 09 15:29:15 if you modify /etc/crontab, send a hup to crond May 09 15:30:36 ok, trying to reboot board, and will check it works after May 09 15:30:48 also May 09 15:30:53 get rid of the & May 09 15:32:07 in most cases that & is essential for background processes, however doesnt matter, i will remove it May 09 15:34:13 hello everyone May 09 15:34:33 cron forks its tasks May 09 15:34:39 so no need May 09 15:40:44 nyt: thank you for your help, problem seems solved May 09 15:41:14 the file /etc/crontab seems not a valid crontab May 09 15:41:52 instead /var/spool/cron/root works (also rebooted board after modifiesd that file) May 09 15:42:23 now it works May 09 15:42:50 hello,, I want to encrypt emmc(rootfs)..http://paxswill.com/blog/2013/11/04/encrypted-raspberry-pi/ May 09 15:42:53 etc/crontab should work May 09 15:42:56 you just need to hup crond May 09 15:43:28 but how to load initramfs into memory May 09 15:43:58 toggle switches and a panel of bus lights May 09 15:44:15 and it should auto load without passphres .. May 09 15:51:30 nyt: i modify /etc/crontab, reboot the board, and cron still not works, if do the same with /var/spool/cron/root then it works May 09 15:51:44 is that a proper thing? May 09 15:52:30 well one is the system cron file May 09 15:52:33 and one is root's cron file May 09 15:52:37 they have different formatting May 09 15:53:00 yepp, in /etc/crontab i have to give user too (and i do so) May 09 15:53:25 in /var/spool/cron/root not need to give user May 09 15:53:44 could that make problem if i want to give root as user? May 09 15:58:27 nope May 09 16:08:22 can someone tell me how to add a command utility to u-boot or point me to some documentation on how this works? I am new to u-boot. Thanks. May 09 16:19:56 waazu, you can look at various examples in the common/ directory May 09 16:26:44 howdy May 09 16:58:38 quit May 09 17:09:00 <__butch__> Simple starter question: how can one tell if they're booted off the SD card or the eMMC? May 09 17:09:42 if u r using linux then use command 'df' May 09 17:10:07 what does it say? May 09 17:11:07 thats ok unless you have same size SD card as eMMC :p May 09 17:11:16 <__butch__> That's a bit of a hard question to answer, since my BBB seems to be bricked at the moment. :-( I was trying to reflash Angstrom, but now I have nothing. :-( May 09 17:11:23 or 'fdisk -l' May 09 17:11:47 i think the eMMC shows up as mmcblk1 and the SD as mmcblk0 ? May 09 17:12:00 <__butch__> That sounds about right. May 09 17:12:24 although it's been a while since i've booted from eMMC with the SD in... May 09 17:12:55 also, i've almost exclusively booted using debian May 09 17:13:53 <__butch__> Based on mount, it appears that I'm booting off the SD card: May 09 17:14:17 <__butch__> e.g.: /dev/mmcblk1p1 on /boot/uboot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro) May 09 17:15:08 <__butch__> Does that seem correct? May 09 17:15:09 the boot device is ALWAYS mmcblk0 May 09 17:15:16 thats irrespective of emmc/sd May 09 17:15:30 <__butch__> OK, -1 for me. :-( May 09 17:15:33 p1 will ALWAYS be fat, p2 will usually be linux May 09 17:15:48 because thats how the bootloader works May 09 17:16:14 so it does get hella confusing :) May 09 17:16:17 been there, done that! May 09 17:16:45 'fdisk' does work if you recognise your eMMC to be 2G/4G for new BBB May 09 17:16:59 hopefullly you have a larger SD .. makes things simpler May 09 17:17:15 then you can see which device is which. May 09 17:17:27 I -think- there may be some hints in dmesg .. but not sure. May 09 17:17:42 <__butch__> OK, there we go. May 09 17:17:48 <__butch__> fdisk is being my friend May 09 17:17:56 <__butch__> 0 is 16GB, 1 is 2GB. May 09 17:18:05 <__butch__> Sooooooo, 1 is eMMC and 0 is SD. May 09 17:18:15 <__butch__> And since 0 is always the boot device, I'm booted off SD. May 09 17:19:00 <__butch__> Thank you for that quick tutorial. May 09 17:19:56 <__butch__> So here's a more general question. I'm going to teach a class on Ruby on Rails (quick one-hour intro) and I thought it would be cool to do it on the BBB. May 09 17:20:13 <__butch__> Everybody gets their own device and some exposure to the coolness that is BBB. May 09 17:20:34 <__butch__> What is a good base OS for this? I'd use Angstrom, but there are certificate issues from hell right now. May 09 17:20:58 use debian May 09 17:21:49 how to use devicetree in bbb May 09 17:22:42 debian is the stock distro for BBB .. or transitioning still .. May 09 17:22:49 should be easy enough to get going May 09 17:23:06 <__butch__> Please to tell more about devicetree. :-) May 09 17:23:51 <__butch__> Why is this relevant to RoR? May 09 17:24:03 difference between devicetree vs platform data May 09 17:24:06 ? May 09 17:24:51 <__butch__> But I'm not trying to muck about with the hardware. I'm really just using this as a very convenient linux SBC. May 09 17:25:10 __butch__ Pi is cheaper and more available ;) May 09 17:25:33 devicetree takes the pinmux/etc out of hard-coding in kernel .. makes it more generic May 09 17:25:57 <__butch__> RPi is far, far, far, far too underpowered for this. I tried already. :-) May 09 17:26:42 hmm ok .. is that because its a different arm core? thuoght they were pretty evenly matched .. but could easily be wrong :D May 09 17:26:50 <__butch__> Roger that on devicetree, but, while interesting regarding easier mapping of the hardware, it's not important to me. May 09 17:27:32 <__butch__> I can't say, because I don't yet have rails up and running, but so far (installing ruby and some other bits), it seems much more capable. May 09 17:27:45 <__butch__> However, having said that, I still have some problems to overcome. May 09 17:28:12 <__butch__> Using debian as a base, I have wireless dongle issues — it's really hard to keep a wireless connection up and running for any length of time. May 09 17:31:05 what is the basics of pinmux May 09 17:31:18 <__butch__> BTW, thanks for the help, folks! May 09 17:36:15 __butch__ whats your wireless adapter? and I assume you've done the textbook thing of attaching it to a powered usb hub :) May 09 17:36:37 you'll probably find the choice of kernel quite critical May 09 17:37:46 <__butch__> Grrrr, ok, now I'm back to the problem I was fighting yesterday. :-( I can't get the eMMC to flash. May 09 17:38:02 are you using the flasher image, or home-brew? May 09 17:38:06 <__butch__> I wrote the SD card, popped it in, held down boot while applying 5v, and nothing. May 09 17:38:23 <__butch__> The only LED lit is the one by 5V. May 09 17:38:26 if using an image .. you need to hold down the SD button for a long time before it acknowledges May 09 17:39:03 <__butch__> I've never seen this before, and I've done it probably 20 times. Not an old hand, but I've gotten it to work many times. :-) May 09 17:39:04 might help to attach a serial debug to watch whats happening May 09 17:39:12 ah okies May 09 17:40:10 <__butch__> Trying BBB #2. Same problem. :-( May 09 17:40:21 your sd image must be broken somehow May 09 17:40:31 writing from 'doze or linux ? May 09 17:40:35 <__butch__> Mac. May 09 17:40:40 ah May 09 17:40:43 <__butch__> So, basically linux. :-) May 09 17:40:46 outa my league there then lol May 09 17:40:54 <__butch__> Nothing special. May 09 17:40:57 you're allowing it to 'sync' ie. write cache out? May 09 17:41:01 <__butch__> Just uncompress then use dd to copy it. May 09 17:41:10 can you mount the imae on the mac? May 09 17:41:13 <__butch__> Yes. May 09 17:41:20 hrm May 09 17:41:40 leds should do their happy dance .. tried a different image, same card, etc ? May 09 17:41:52 same image, different card? May 09 17:42:02 <__butch__> I'm trying a different image now, but the same SD card (I have only one). May 09 17:42:15 and you're had success before .. hrm.. weird. May 09 17:42:35 <__butch__> Yes, and it mounts properly on the Mac, so I'm guessing it's at least somewhat correct. May 09 17:42:54 yea .. you see both partitions, right? May 09 17:43:20 <__butch__> I didn't look. May 09 17:43:31 <__butch__> I'm dd'ing a new image now. May 09 17:43:35 covering all bases :) May 09 17:44:33 <__butch__> I don't even know why I want to flash it, since I'm going to run off the SD card anyway. May 09 17:44:46 <__butch__> The problem I was having yesterday is that I couldn't get it to boot off the SD card. May 09 17:44:59 <__butch__> And there wasn't enough space on the eMMC to install ruby and rails. May 09 17:45:11 yea it soon adds up May 09 17:45:30 <__butch__> Soooooooo, when this exercise is over, I'll be booting debian off the SD card (I hope). May 09 17:45:48 <__butch__> Can I start drinking now? Please? May 09 17:46:01 yeah don't need a flasher image to boot from ;) May 09 17:46:02 lol May 09 17:46:48 I've found the board will boot from SD without the button, if the emmc is right May 09 17:48:25 <__butch__> Well, hopefully I can get it flashed properly and all will be correct enough for it to automagically boot from SD. May 09 17:48:39 <__butch__> The whole thing seems just a bit fragile to me. May 09 17:48:50 you don't *have* to have the bootloader on a FAT partition, most versions of u-boot support ext2 May 09 17:49:54 I thought the TI looked for the bootloader on a fat before it GOT To uboot ... May 09 17:50:13 <__butch__> Image written to SD card. Now, should I try to flash it, or just see if I can boot to SD? May 09 17:50:47 pretty sure you needed a FAT for some critical part of the boot process .. or Rob Nelson woulda stopped using it with his images. May 09 17:51:01 since he already patched uboot :) May 09 17:51:10 for Zimage not uImage iirc. May 09 17:51:42 <__butch__> OK, in theory debian is now being flashed. May 09 17:51:47 i've made images without a FAT partition and booted them. May 09 17:51:57 <__butch__> There must be something wrong with that image that I was using before (Angstrom). May 09 17:52:08 probably __butch__ :) May 09 17:52:19 i think the beagleboneblack images have the FAT partition to make it easier to edit from non-linux machines. May 09 17:52:30 vagrantc: exactly. May 09 17:52:43 vagrantc .. I know on other systems you can DD a block into non-partitioned space May 09 17:52:51 but thats pretty icky May 09 17:53:16 jkridner .. makes sense I suppose May 09 17:53:19 that's how i felt at first, but i've grown to like them. May 09 17:53:30 the ones where you dd to a specific address... May 09 17:53:36 in a partition .. you cna SEE the file May 09 17:53:47 thats gotta be easier to troubleshoot May 09 17:54:10 but yea .. other platforms use that system .. don't personally like it :) May 09 17:54:21 especially because with the MLO on a filesystem, it has to be the *first* file on the filesystem or it doesn't work... so rm MLO ; cp newmlo MLO doesn't work. May 09 17:54:31 so the filesystem support is a little illusury May 09 17:54:39 vagrantc .. never had that problem myself May 09 17:55:09 veremit: well, there's code in rcn's image generation to make sure that's the case May 09 17:55:24 oh. May 09 17:56:13 although the workaround i use is "dd if=newMLO of=MLO" and that seemed to work, when i needed to update u-boot from the filesystem rather than regenerating the image May 09 17:56:45 not sure what the technical requirements are... this is sort of learning by experimentation May 09 17:57:04 vagrantc .. very true ;) May 09 17:57:20 never tinkered wiht MLO thankfully .. May 09 17:58:13 its a big learning curve though May 09 17:58:15 <__butch__> @vagrantc That relies on the files being (essentially) the same size (i.e. if the new file is longer, one better hope there's not something abutting it in the filesystem, or all sorts of evilness can occur). May 09 17:58:57 fair point. May 09 18:00:29 the MLO for the BBB appears to be around 77k... what's the default block size on fat? May 09 18:00:50 guessing at 16k? May 09 18:01:21 depends on the partition size no? May 09 18:01:30 I remember 4k clusters too May 09 18:06:15 bbiaf .. May 09 18:09:18 Hello May 09 18:09:42 how to deal with PWM pins across /sys/class/pwm ? May 09 18:10:35 I have tried somethin like echo "23" > /sys/class/pwm/export like for GPIO pins, but it said that "No such device" May 09 18:36:20 <__butch__> Rather than fight with this again for the 1E37th time, I'll just ask. What's the easiest way to get Wi-Fi up and running with debian and an Edimax WE-7811Un? May 09 18:37:41 __butch__: use connmand to configure it May 09 18:38:16 <__butch__> Please to explain? :-) May 09 18:39:22 __butch__: https://wiki.archlinux.org/index.php/Connman May 09 18:40:14 <__butch__> Hmmmm, hadn't seen that before. Thanks! May 09 18:40:24 __butch__: I don't remember details, but there are my config files :) https://gist.github.com/Ignotus/27ee9ff243244c291b61 May 09 18:40:36 <__butch__> One needs to start by enabling the interface, though, yes? May 09 18:40:50 <__butch__> So edit /etc/network/interfaces and uncomment it? May 09 18:40:51 is connman easier than NetworkManager? I personally live wiht wpa_supplicant old-skool :D May 09 18:40:53 __butch__: you can add several wifi networks to the wifi.config May 09 18:41:21 veremit`AFK: I think so May 09 18:41:44 gonna have a play with Arch one day, will give it a roll .. wifi config is a pain May 09 18:42:00 veremit`AFK: works for me :) May 09 18:42:08 though looks like I got a small learning curve from gentoo/debian :/ May 09 18:42:08 <__butch__> Ummmmm, but there's a small problem: no connmanctl command. :-( May 09 18:42:17 apt-get install connman May 09 18:42:17 __butch__: opkg install May 09 18:42:23 ewww opkg eww May 09 18:42:32 lol May 09 18:42:44 debian guy detected May 09 18:42:51 <__butch__> Yes, but that requires network connectivity. :-) May 09 18:43:03 plug the frckin wire in .. ffs .. May 09 18:43:08 __butch__: you can download this package May 09 18:43:10 why everyone insists on wifi ... May 09 18:43:13 <__butch__> I don't have a frickin' wire. :-) May 09 18:43:14 and do scp May 09 18:43:17 throw ssh May 09 18:43:40 or I think it's possible to configure the network throw USB May 09 18:43:45 yeah that requires a network lol :p May 09 18:44:03 put the file on a SD card .. old skool XD hehe May 09 18:44:13 <__butch__> OK, so back to using scp. Where does the package live? May 09 18:44:29 __butch__: ... in the repository? :) May 09 18:44:35 <__butch__> Or should I just continue to do this the hard way, where I somehow make it work using iw and other things? May 09 18:44:39 __butch__: are you using angstrom? May 09 18:45:11 <__butch__> See above ^^^^: debian May 09 18:45:39 __butch__: so find it in the debian repository :) May 09 18:45:55 <__butch__> Yeah, thanks, that much I knew. I was hoping to not have to go hunt. :-) May 09 18:46:10 yeahno .. repo hunting if you're not networked .. is fun :D May 09 18:46:20 __butch__: https://packages.debian.org/wheezy/connman May 09 18:46:36 hehe at least there's that ^^ May 09 18:47:13 getting distfiles for gentoo .. especially old/obsolete ones -sigh- May 09 18:47:15 all part of the joy of linux :) May 09 18:47:26 My question about /sys/class/pwm .. . if somebody know about it, please answer :) May 09 18:48:53 wicd is on the BBB Debian images... May 09 18:49:03 last i looked. May 09 18:49:13 vs. connman, which we had tried for a while May 09 18:49:17 <__butch__> Cool. Thanks for that pointer. Let's see how that goes. :-) May 09 18:51:23 <__butch__> So let me tell you what I've tried in the past. 1) configure /etc/network/interfaces (no ESSID or passphrase), 2) iw wlan0 essid THE_ESSID (open network), 3) ifup wlan0, 4) iwconfig to see if it's doing anything, 5) do the chicken dance, pray to Jobu, etc. May 09 18:51:36 <__butch__> Any reason not to follow these steps? :-) May 09 18:52:13 don't think network/interfaces does security does it .. unless it passes it onto something May 09 18:52:19 wicd is aweful .. don't use that. May 09 18:52:42 like many things, network management is a matter of personal preference... May 09 18:52:44 wpa_supplicant , although complicated , has a good example config .. and usually *just works* May 09 18:53:05 you can also use wpa hooks from /etc/network/interfaces May 09 18:53:08 for out-the-box in a window manager .. I like NetworkManager. May 09 18:53:17 vagrantc .. thught that might beone method May 09 18:53:35 iwconfig is the alternative to wpa .. but it won't do WPA ? May 09 18:53:44 there's some caveat May 09 18:54:05 zless /usr/share/doc/wpa_supplicant/README.Debian.gz May 09 18:54:15 then simply ifup / ifdown work. May 09 18:54:54 if you're not going to use a frontend, i find that to be the easiest... YMMV May 09 19:11:06 hey guys i had a question. I initially thought i had not activated an overlay properly but was able to get my bealgebone black to use ttyo2 properly with a hc-05 bluetooth module. however when using an apc220 i am not receiving any information on the port. would this be a sign of needing to use a logic level converter May 09 19:28:46 hi. i need help to build a multimedia sensor node. i want to make sure that i can do it using bbb May 09 19:43:54 it depends how hard you try .. May 09 20:06:44 does anyone know how on the beaglebone black to disable the regular webserver May 09 20:09:18 first step is figuring out which one it is :) May 09 20:11:58 Starsoccer: systemctl May 09 20:12:04 yes i just found it May 09 20:12:08 doing it now May 09 20:12:27 last question any idea where the file is to edit lighttdp to make it port 80 May 09 20:12:36 I had changed it to port 8080 May 09 20:12:43 but now that I can disable them May 09 20:12:44 ... May 09 20:14:18 Starsoccer: I think this info can be easy found by google :) Probably somewhere in /etc/*httpd* May 09 20:15:08 probobly, just lazy May 09 20:15:08 lol May 09 20:15:17 Starsoccer: mine is in /etc/httpd/conf/httpd.conf May 09 20:16:24 my* May 09 20:18:53 mine was just in etc called light w.e. .conf May 09 20:18:57 well anyways thing I did it May 09 20:19:00 just rebooting now May 09 21:18:36 Does anyone have details on how to get full GPIO use out of the P8 header of the BBB RevB? May 09 21:19:43 I got the BBB only B/C it had as many GPIOs as it did, just to find out that all the features use "all" the headers May 09 21:33:37 i'm not sure i was connected correctly before so i'm i'm reposting please forgive me. If someone could say hi just so i know i am connected that would also be helpful. May 09 21:34:51 I got the BBB B/C of the number of GPIOs that it had but found it's features use most of these. Does anyone have a guide on fully utilizing the P8 header as GPIO? May 09 21:36:02 I have already disabled emmc and hdmi; however the emmc pins are still set to input tied high (test circuit LEDs are barely lighting) May 09 21:37:34 who May 09 21:40:59 get3: sup May 09 21:41:07 shade34321: sup May 09 21:53:53 get3_: sounds like you need to get religion May 09 21:53:56 or devicetree May 09 21:54:00 same difference May 09 21:55:11 seriously, adafruit has a really great tutorial on this May 09 22:02:51 i've been looking; can you point to any specific guide? I have tried making my own virtual capes; no luck. May 09 22:03:38 What i have found that uses those pins is in the default modules of which i'm considering changing to truely free those pins. May 09 22:05:01 everything says that they are in mode 7, output, pull up... but still when i plug them in i see emmc status on the LEDs. Before i disabled the eMMC virtual cape the LEDs would blink even when they were in GPIO mode... May 09 22:11:12 get3_: you need to load overlays May 09 22:11:13 to use the pins May 09 22:11:17 as hdmi May 09 22:12:01 or modify the default dtb May 09 22:12:06 which sets them as emmc / hdmi May 09 22:12:08 either way May 09 22:12:21 https://github.com/notnyt/beaglebone will generate and load dtb overlays as required when using pins in hdmi mode May 09 22:12:23 as will bonescript May 09 22:12:29 if you want to see from code, the one i linked is easier to follow May 09 22:14:01 https://drive.google.com/folderview?id=0B0XzvqNi9HIdM0dZS3VHVDlwQWM&usp=sharing nyt May 09 22:14:13 i am making this. i need help with some asthetics May 09 22:15:02 i feel like the chamfer on the edge is too much, i might also socket cap screws which will stick out a little but double as feet May 09 22:15:42 as opposed to the current configuration with countersunk screws which the countersink interfere with the contour May 09 22:16:14 the socket caps diameter is smaller so the counter bores wont spill over the edges May 09 22:16:33 such ugly :( May 09 22:16:52 well tell me what to do, doge May 09 22:17:14 i can engrave some boobies in there May 09 22:17:20 whatever May 09 22:17:25 go full case if youre gonna go w/ that much medal May 09 22:17:26 metal May 09 22:17:28 or May 09 22:17:33 well if its metal thats really your choices May 09 22:17:33 haha May 09 22:17:35 im using this guy May 09 22:17:37 and like it May 09 22:17:54 well i wanted an open design May 09 22:18:01 hm no longer on amazon May 09 22:18:14 but... since i cant get my hands on a bbb its hard to prototype a close fitting case May 09 22:18:16 http://lasergoodies.com/blog/2013/10/21/slim-beaglebone-black-case-clear May 09 22:19:03 oh yeah that's a goodie May 09 22:20:13 ok well :P May 09 22:20:47 i want to cnc one of those May 09 22:20:54 do it May 09 22:20:57 they dont sell it on amazon anymore May 09 22:21:08 i have to buy one and reverse engineer it May 09 22:21:10 lol May 09 22:21:20 cuz i cant get a bbb May 09 22:21:24 well May 09 22:21:28 you ordered right? May 09 22:21:34 long time ago May 09 22:21:40 youll have soon May 09 22:21:41 but if you want May 09 22:21:44 i can scan the parts for you May 09 22:22:01 with a 3d scanner? May 09 22:22:16 no May 09 22:22:18 with a flatbed May 09 22:22:30 i'll measure the height for you May 09 22:22:34 and the dimensions May 09 22:22:40 you can then figure out the rest lol May 09 22:22:45 oh theres some dxf of those parts on the web May 09 22:22:54 ok May 09 22:23:22 but ... i am so used to seeing parametric modeling with real dimensional and geometric callouts built in May 09 22:23:51 i dont trust it... May 09 22:24:32 question May 09 22:24:49 are the outsides exactly flush with the pc May 09 22:24:53 pcb* May 09 22:25:13 no May 09 22:25:20 in order to wrap around the headers May 09 22:25:23 it sticks out beyond the pcb May 09 22:26:08 if you gave me basic dimensions (height and width) of the top view i could make it May 09 22:26:59 i will make the inner layers acrylic because its nonconductive May 09 22:27:11 and the outer layers 6061 May 09 22:27:55 4 layer right? May 09 22:28:08 yes May 09 22:28:14 ill get you info in a bit May 09 22:28:15 remind me if i dont May 09 22:28:17 ty May 09 22:28:23 ok no problem May 09 22:42:45 Is there a reason a flash friendly filesystem was not chosen for the default images? May 09 22:42:56 *facepalm* May 09 22:47:15 *double facepalm* May 09 22:54:59 flash friendly, like wear leveling fs, or the size of the images? May 09 22:55:09 i don't believe eMMC needs any special fs May 09 22:55:25 hw handles the dirty work May 09 22:55:38 pdp7, f2fs or jffs2 for example May 09 22:55:54 ah, i don't think needed since eMMC is the onboard flash May 09 22:56:01 and not raw NAND flash May 09 22:56:26 pdp7, ok, so the eMMC has smarts like a SSD for wear leveling? May 09 22:56:36 yeah, i think so... May 09 22:57:28 maybe others know more, but that is my impression May 09 22:58:28 for example from the rev C BBB BOM May 09 22:58:29 https://www.micron.com/parts/nand-flash/managed-nand/mtfc4gldea-0m-wt May 09 22:58:29 in that case I might leave the root fs on the eMMC and run F2FS on a SD card for more space May 09 22:58:38 yeah, that prob good idea May 09 22:58:49 i believe gerald likes the eMMC bc of the reliaability May 09 22:59:13 my BBBs are rev b, but should be very similar chip, only the size is different? May 09 22:59:31 oh, similar chip, diff size, i was just looking for one of the sku's May 09 22:59:36 so i could find the datasheet May 09 22:59:45 micron has good faq... "e•MMC is a fully managed solution (all media management and ECC are handled internally), making NAND technology transitions invisible to the host and providing customers with the ability to reduce their time-to-market and to sustain products longer and more easily." May 09 23:00:22 this is rev B: https://www.micron.com/parts/nand-flash/managed-nand/mtfc2gmvea-0m-wt?source=ps May 09 23:00:34 thanks May 09 23:01:54 pdf: http://www.micron.com/-/media/Documents/Products/Product%20Flyer/e_mmc_flyer.pdf May 09 23:02:01 don't mind the flip phone ;) May 09 23:02:33 ooo May 09 23:02:36 jkridner May 09 23:02:39 new header images are sanzzy May 09 23:02:40 snazzy May 09 23:03:01 images? May 09 23:03:05 http://beagleboard.org/Support/bone101#headers May 09 23:03:17 nice May 09 23:03:19 ty May 09 23:04:18 haha, that is quite funny, the chick and the london egg looks current May 09 23:05:10 oh, that building in london May 09 23:06:09 http://www.schefferj.ps.hu/images/England/En_London/TheEgg_800.jpg May 09 23:06:13 looks like that is it May 09 23:06:27 are there any docs for using the timer pins somewhere? May 09 23:07:41 like for pwm? May 09 23:08:08 no, they're timers May 09 23:08:12 pwm separate May 09 23:11:31 Where is the documentation about connecting the BBB to the internet over USB? May 09 23:12:09 Or can anyone explain the process? May 09 23:20:30 Guest79200: How it works, or how to do it? May 09 23:28:13 what are the emmc flasher images for? May 09 23:28:28 is that an image you boot off SD card that then reflashes the emmc? May 09 23:28:56 k-man: yup May 09 23:29:33 Guest79200: i've done it once or twice with my linux laptop... was annoying so switched to direct ethernet May 09 23:30:00 it would depened on you computer's OS May 09 23:34:19 pdp7, thanks May 09 23:39:55 hello? May 09 23:41:27 does anyone know the User LED codes for the BeagleBone Black? I have the USER2 LED stuck on after powering up May 09 23:51:41 think thats hearbeat? May 09 23:51:47 is your system responsive? May 10 00:13:36 nyt.. basic dimensions to this precision plz: .001 May 10 00:13:44 " May 10 00:13:50 :D May 10 00:14:21 chop chop May 10 00:14:31 :D May 10 00:18:14 will get to it tonight May 10 00:18:17 dealing w/ server upgrade fun atm May 10 00:18:22 keep reminding me May 10 00:59:46 Hi, I'm looking for a small touchscreen cape for the BBB (4" is fine) that lets me use the pins that it's not using. Ideally, I'd like 30-32 pins on P9 and access to 3.3V and GND. Will I have to put a cape inbetween the touchscreen cape and the BBB, and if so, where should I look for that middle cape? May 10 01:00:19 (access to 5V is also good, but may not be required) May 10 01:02:16 yes i recommend using this May 10 01:03:48 http://www.seeedstudio.com/depot/43-LCD-Cape-for-BeagleBone-Black-Touch-Display-p-1592.html May 10 01:03:49 for an lcd May 10 01:03:50 just works May 10 01:03:52 and for cape... May 10 01:06:58 yeah that LCD looks good, but I still need access to ~32 GPIO pins for the other part of the project May 10 01:10:05 is this what the breakout cape is for? http://www.digikey.com/product-detail/en/BEAGLEBONE-BREAKOUTCAPE/BEAGLEBONE-BREAKOUTCAPE-ND/2805398 May 10 01:12:19 I'm very novice when it comes to EE, unfortunately, so I'm still trying to figure all this stuff out **** ENDING LOGGING AT Sat May 10 02:59:59 2014
