**** BEGIN LOGGING AT Sat May 19 02:59:59 2012 May 19 03:55:33 I'm getting up and running with my beagle bone and had a question about the gpios. I'm trying to use GPIO1_7 and GPIO1_12 as digital outs. I do an identical sequence of operations (with different pin numbers). When i'm done, GPIO1_12 works as a digital out, and GPIO1_7 does not (it remains forever high). any ideas what's going on? May 19 03:56:06 is there something special about 1_7 and 1_3 (i see identical behavior in each of those) May 19 03:57:18 you exporting it correct? May 19 03:57:22 *correctly May 19 03:57:34 i.e. mux setting isn't something else May 19 03:57:50 yeah May 19 03:57:58 i've found a post that says that it's not set to GPIO on boot May 19 03:58:07 which is weird, because in the reference manual it looks like it is May 19 03:58:11 you sure you have it in the right pun May 19 03:58:13 *pin May 19 03:58:17 https://groups.google.com/forum/?fromgroups#!topic/beagleboard/oWulB8CO0gc May 19 03:58:27 drinking and typing sucks May 19 03:58:37 :) May 19 04:01:48 it sounds like using bone script reconfigures GPIO to make that pin work May 19 04:08:20 I am trying to bitbake gstreamer-ti.it gives me error Checksum mismatch May 19 04:08:34 can anyone suggest a solution May 19 04:12:57 did you make the .bb file? May 19 04:16:12 when you write to the mux configuration files (/sys/kernel/debug/omap_mux/), are the values supposed to be hex or dec? May 19 04:18:47 I used command bit-bake gstreamer-ti May 19 04:19:09 sorry bitbake* May 19 04:47:52 Is there any way to write to a cape's eeprom while it's attached? It seems the kernel keeps it open all the time May 19 04:48:01 Also, why doesn't I2C2 show up in the FS? May 19 05:32:04 can anyone recommend a breakout that will step 5 to 1.8 for beagleboard/bone? May 19 05:37:40 Borillion: I got a level shifter from sparkfun May 19 05:37:57 its the only one I could find that was throughhole so i could breadboard it easily May 19 05:38:33 k, I was looking at that but how do you get the 1.8 out on the lv side? I don't see how to set the output LV voltage ? May 19 05:38:52 how does one remove the default web server that's running on the beagle bone angstrom distro? May 19 05:39:13 i've installed lighthttpd, but i'm not sure what i need to remove to kill what's running on port 80 now May 19 05:40:44 Borillion: it looks like you might have to modify it a bit to go from 5 to 1.8 May 19 05:40:53 but its just resistors May 19 05:41:48 looks like they are 0603 package so they are easily replacable May 19 05:42:32 Borillion: do you need to go both ways? as in 5 to 1.8 and 1.8 to 5 May 19 05:43:00 because to go from 5 to 1.8 is just a simple resistive divider and you don't really need a level shifter for it May 19 05:48:01 no its going to have to be both ways May 19 05:48:18 I cant use a divider for this May 19 05:48:38 I was under the understanding everything on the beagle headers was at 1.8V May 19 06:19:44 saliak: just disable it at startup.. check out init.d and runlevels May 19 06:56:56 anybody in the room know much about writing and compiling loadable kernel modules? May 19 06:58:18 * mranostay facepalms May 19 09:21:05 How can I know which shell I'm using on my beagleoard-xm? I'm running ansgtrom. May 19 09:25:12 <_av500_> ps May 19 09:26:10 Oh.. That returned sh. I'm sorry but is 'sh' the same as 'bash'? May 19 09:26:18 type $SHELL May 19 09:26:49 sh is not bash, sh is most likely ash , and possibly you have busybox May 19 09:27:34 Ummm.. Does that mean I cannot use .bashrc to set my environmental variables? That is how I do it on bash. May 19 09:30:16 install bash, then export SHELL=/bin/bash May 19 09:30:25 <_av500_> ls -l /usr//sh May 19 09:30:30 <_av500_> ls -l /bin/sh May 19 09:31:18 @_av500_ That shows sh -> busybox May 19 09:31:45 @fireman Do I need to do that each time I restart my XM in order to use bash? May 19 09:31:59 blucalvin: no, you can set that in your profile May 19 09:32:19 and in /etc/passwd May 19 09:33:00 Which profile wold that be? May 19 09:33:35 http://stefaanlippens.net/bashrc_and_others May 19 09:33:46 that will explain all you need to know now about bash May 19 09:34:10 just remember to set default shell in /etc/passwd May 19 09:34:33 Thanks. :) I'll do that. I wanted to set the http May 19 09:35:00 (i just googled. first result on 'profile bash' ) May 19 09:35:12 Thanks. :) I'll do that. I wanted to set the http_proxy variable in my .bashrc. That's when I found out that file was not there in my home folder. May 19 09:46:30 I put "export SHELL=/bin/bash" in my /etc/profile file. But after restarting, "ps" is showing "sh" and "echo $SHELL" is showing "/bin/bash". So which am I using now? May 19 09:47:25 use chsh May 19 09:48:54 in chsh, I entered "/bin/bash" and still "ps" is showing "sh" May 19 09:49:14 you have torelogin May 19 09:49:30 Ah Alright. May 19 09:49:55 Now it works. :) May 19 11:51:35 Hi May 19 14:24:09 does it makes sense that installing mysql would break my ethernenet connection on the beagle bone with the default angstrom build? May 19 14:25:04 no May 19 14:27:51 Hi, I want to join the Beagleboard Google Group and requested approval but few days pass and still not approved, do you know how long it takes to review and apprve new members to the group? May 19 14:29:27 * koen stabs syscall table generators May 19 14:30:01 awesome. hrm. dunno what would be going on. wanted to get a LAMP setup (well, LLMP, using lighthttpd).. got lighthttpd and php installed, but after installing mysql eth0 wouldn't com up. uninstalled it and things work fine. May 19 14:31:33 that's weird even for mysql May 19 14:31:50 but isn't mysql a bit heavy for the bone? May 19 14:33:16 maybe the systemd-integration of mysql is broken on the bone May 19 14:33:53 s/bone/angstrom/ May 19 14:34:32 <_av500_> why does it need systemd integration? May 19 14:34:39 aholler: that's what i was thinking. i'mnot sure what though. maybe the order that it starts up or something? It did have a broken reference to something in init.d (/rcS) that i commented out May 19 14:34:56 _av500_: to start the daemon at boot, yeah? May 19 14:35:03 saliak: just try to disable it May 19 14:35:48 you can always start it by hand May 19 14:36:04 aholler: i already removed it. given it took like an hour to install, and I can use flat xml files for what i need to do, i think i'm going to skip it for now May 19 14:36:32 so why you asked? May 19 14:36:40 aholler: mostly just curious May 19 14:36:59 can anyone recommend a kernel workflow other than the one on the angstrom homepage? May 19 14:36:59 aholler: starting by hand (in my code) later probably makes sense. i bet its a timing thing May 19 14:37:34 I had to change the start_ and shutdown_timeout on an armv5-system here May 19 14:37:58 otherwise mysql didn't start inside the timeout because it needed to long May 19 14:38:43 but that depends on the init-script May 19 14:39:27 and, off course, the system, e.g. where your dbs are living and such May 19 14:42:14 aholler: i'm not familiar with the _timeouts. pointer to something that describes them? May 19 14:42:27 the init-script May 19 14:43:06 the one in gentoo e.g. checks for the existence of the control-socket to check if mysqld started May 19 14:43:41 I don't know if that is included in the std-init-script of mysql too May 19 14:44:21 aholler: i'm not sure i follow. are you referring to stuff in /etc/rcX.d? or /etc/init.d? May 19 14:44:43 I can't help you with that on angstrom May 19 14:45:05 aholler: ok. yeah, i'm more familiar with ubuntu. this is all a little differenct May 19 14:48:05 aholler: yesterday when I was having bitbake problems you suggested a different process for modifying the kernel. Is there a method you suggest? May 19 14:48:37 serekson: the one everyone outside oe/angstrom uses, git and make May 19 14:49:00 is there a guide you recommend to doing this? May 19 14:49:08 the one on the angstrom homepage was really simple May 19 14:49:08 thousands May 19 14:50:00 git clone ...; make ... May 19 14:50:02 I have been trying to get https://github.com/beagleboard/kernel to work, but I am having problems booting it May 19 14:51:10 I think the issue is that uboot can't find it May 19 14:53:35 I need I need to use somethign like that to get the right patchset for the kernel? May 19 14:58:13 anyone familiar with a lower end single board computer for less then the price tag of beaglebone? no rpi either as I need 50+ ASAP May 19 14:58:58 what specs do you need? May 19 14:59:59 all i would need is embedded linux and wifi - i will be perorming very low resource tasks, like making remote api calls and downloading images May 19 15:22:34 mru: you suggest anything to me to look into? May 19 15:22:50 what specs do you need? May 19 15:23:03 you said "low resource" but that could mean anything May 19 15:23:13 would an arm926 with 32MB ram do it? May 19 15:23:29 running at, say, 200MHz May 19 15:24:05 yeah that would be perfect 200mhz/32mb ram May 19 15:24:28 then there are probably hundreds of modules that would work May 19 15:24:40 i dont think I would need any more then that for remote http calls and downloading small images so yeah. May 19 15:26:04 what software do you plan on running? May 19 15:26:11 and what will you do with the images? May 19 15:26:56 debian would be ideal, the images will be sent over usb port to printer May 19 15:27:16 debian can mean anything May 19 15:27:35 but talk of usb printers is scary May 19 15:28:15 if it works on desktop debian for usb printer, whats changing when I go to a arm board? May 19 15:28:17 usb and printer usually means full processing of the print data on the host May 19 15:28:25 exactly May 19 15:28:28 im new to the hardware world, im just average linux users May 19 15:28:46 which means you need enough ram to hold a full rasterised page May 19 15:28:52 preferably several pages May 19 15:28:53 which printer? has it open source drivers? May 19 15:28:54 ahhh gotcha! May 19 15:29:30 jannau: if im not mistaken its a canon pixma - got it working on ubuntu without issues May 19 15:30:41 so i will more then likely need more ram huh. May 19 15:36:27 funkster: exact model? it might be only work with binary drivers from canon which are most likely only available for x86 May 19 15:36:46 run them in qemu :) May 19 15:37:10 dont have the printer infront of me at the moment - hmmmm May 19 15:37:30 mru: on a 200mhz/32mb ram arm9? May 19 15:37:43 there is an option for me to use another printer and send it via bluetooth i guess i will try both options May 19 15:37:57 jannau: is that any crazier than running ubuntu on a beaglebone? May 19 15:39:00 crazy on a different level and I would claim running ubuntu on any hardware is crazy May 19 15:39:47 exactly May 19 15:40:30 perhaps there is an other way - I used it long time ago on an openwrt router. It was something like a printer-forwarding-pipe. I do not remember the name - sorry. but no printerdriver on the embedded device was needed. May 19 15:41:04 it's lpr May 19 15:41:12 koen: https://github.com/prpplague/fb-test-app/tags May 19 15:42:43 koen: use commit 1547b55320db31eba7af4020f0ca0298ec42cef1 May 19 15:42:52 koen: for the release, tag is v1.0.0 May 19 15:44:00 where can i purchase a low cost 200mhz/32mb arm board to test? May 19 15:44:13 my googling is not giving me boards under 100 lol May 19 15:44:51 funkster: http://search.digikey.com/us/en/cat/programmers-development-systems/general-embedded-dev-boards-and-kits-mcu-dsp-fpga-cpld/2621773?k=beaglebone May 19 15:45:23 prpplague: nah - looking for low end 200mhz boards so the price is much cheaper May 19 15:45:39 funkster: you will need to be more specific about "low end" May 19 15:45:53 prpplague: ok, you give it a try... May 19 15:46:15 i will start out with what mru suggested 200mhz/32mb ram May 19 15:46:19 mru: ahh i assume it has been an ongoing issue May 19 15:46:22 I didn't suggest anything May 19 15:46:33 * prpplague is too busy to deal with stupid questions today May 19 15:46:41 those figures were just something I made up May 19 15:46:50 How is it a stupid question... wtf? May 19 15:47:19 you said how about xyz, i said ok to xyz - sorry if i called that suggesting... May 19 15:47:30 funkster: if you'd be a bit more precise in what what you intend to run than "debian", we'd be able to give better suggestions May 19 15:48:12 yes im just confused on what info you will need - as stated, i will be downloading 1MB images and printering them via USB printer May 19 15:48:17 thats pretty much it May 19 15:48:23 downloading with what? May 19 15:48:29 how will you know what to download? May 19 15:48:41 what printing software will you use? May 19 15:48:48 how will you tie it all together? May 19 15:49:18 I will make remote api calls via curl to get download url , so curl/bash/etc May 19 15:49:38 any kind of user interface? May 19 15:50:13 nope, user interface will be on the remote server May 19 15:50:38 that still doesn't resolve the printer driver/memory problem May 19 15:50:48 agreed May 19 15:51:02 so how will this system know what to fetch? May 19 15:51:08 what kind of pictures, printed on full a4/letter? May 19 15:51:12 periodic polling? May 19 15:51:39 sure - i will cron a curl/bash script May 19 15:51:59 and that will fetch some images... what kind of images? May 19 15:52:02 jannau: it will be 4x6 photos May 19 15:52:02 format? size? May 19 15:52:15 photos - max size 1MB May 19 15:52:20 jpeg May 19 15:52:26 how many pixels? May 19 15:52:39 that would range drastically May 19 15:52:47 maximum May 19 15:54:16 lets say 1024x800 ish May 19 15:56:15 that's a bit small for a 6x4 print May 19 15:57:10 it will be in a polaroid format - so some white space on bottom/sides May 19 15:57:56 may even make 3x4 once i test some things May 19 16:03:57 funkster: still depends on the printer (driver), I guess an openwrt based router might not an bad option for cheap and low volume May 19 16:05:18 yeaah - hmmmm May 19 16:06:11 do routers have usb ports these days? May 19 16:06:31 they have since 5 years May 19 16:06:38 what for? May 19 16:07:01 to connect usb storage May 19 16:07:11 storage on routers? May 19 16:07:12 wtf? May 19 16:07:17 connect 3g, mass storage, printers, ... May 19 16:07:34 why would you want to do that? May 19 16:07:57 "network" stoage and printer May 19 16:08:18 think of it as slow combined router/server May 19 16:08:35 have people no sense any more? May 19 16:09:08 but 3g modem as backup connection might be useful on a router May 19 16:09:23 yes, that I can agree with May 19 16:09:46 wouldn't do me a whole lot of good though May 19 16:10:00 people lost sense in the last century, marketinng people a couple of decades earlier May 19 16:10:29 marketing people, isn't that term a bit contradictory? May 19 16:22:04 koen: hope you like the version codename, hehe May 19 16:22:32 koen: (yes it is a joke) May 19 16:34:14 usb-ports on routers are common since 10a May 19 16:35:33 since the 25-pin ports on printers started to disappear May 19 16:39:46 i may just go mini-itx x86 route if im dealing with these printers May 19 16:53:37 prpplague: pink table, nice May 19 16:54:21 koen: you know what it is suppose to be right? May 19 18:11:28 when I compile helloworld using "arm-linux-gnueabi-gcc helloworld.c" and put it on the beagleboard i get "cannot execute binary file" May 20 02:19:11 * mranostay yawns May 20 02:44:36 Good news! May 20 02:44:55 Hmm? May 20 02:45:24 Oh just getting some stuff done with this alarm system, **** ENDING LOGGING AT Sun May 20 02:59:58 2012
