Apr 04 03:37:31 woo Apr 04 03:37:35 my ruby lib is comign nicely Apr 04 03:37:43 just wrote shift reg code Apr 04 03:37:43 so nice Apr 04 04:57:16 hi Apr 04 04:57:20 hell? Apr 04 04:57:22 hello? Apr 04 04:57:42 아무도 없으시무니까 Apr 04 04:59:05 This is my black beagle is not connected to the laptop Why is this? Apr 04 04:59:38 anybody there?! Apr 04 05:00:21 http://www.catb.org/esr/faqs/smart-questions.html Apr 04 05:05:03 hey Apr 04 05:05:53 hello Apr 04 05:05:55 you could start by explaining your situation Apr 04 05:05:55 hello? Apr 04 05:06:01 instead of repeating yourself Apr 04 05:07:11 my black beagle is not connected to the laptop Apr 04 05:07:28 then connect it, either by USB or by Ethernet Apr 04 05:07:29 yesterday, connected Apr 04 05:08:14 which operating system are you running on your BBB? Apr 04 05:09:52 my operating system is ubuntu Apr 04 05:11:25 what did you do yesterday with your ubuntu installation on the BBB? Apr 04 05:14:12 i don`t know... Apr 04 05:14:13 suddenly doesn`t usb connection Apr 04 05:16:28 then either connect to the debug UART or over Ethernet/LAN. Apr 04 05:16:43 If you can't do that, then just reflash the board Apr 04 05:18:06 what is mean refresh? BBB change? reset? Apr 04 05:20:01 reFLASH not refresh Apr 04 05:20:23 as in reinstall ubuntu on it Apr 04 05:25:36 i have two BBB Apr 04 05:25:50 but another bbb is not connected Apr 04 07:48:51 hi Apr 04 07:48:51 any one there Apr 04 07:49:06 hi Apr 04 07:49:22 hi Apr 04 10:33:23 I know it's super early but, I have a beagle-bone a4 white and I can't get it to get an ip address, I am pretty sure it's booting. I tried the fix that requires removing a resistor (r219) but it still won't work, this was with archlinux installed Apr 04 10:33:36 I know the cable was good and the router is new Apr 04 10:34:00 I am at a loss Apr 04 10:34:16 which os is on the board? Apr 04 10:36:24 hm Apr 04 10:36:25 Fun, thank you for responding, I put archlinux on the board Apr 04 10:36:37 I have two sd cards Apr 04 10:36:47 onca: connect a serial cable and see what it is doing Apr 04 10:37:05 I tried, I don't know why but there is no /dev/ACMtty anything Apr 04 10:37:14 I have it in front of me Apr 04 10:38:30 what os do u have on your computer? Apr 04 10:38:35 ubuntu Apr 04 10:38:36 maybe because its ttyUSB? Apr 04 10:38:44 see syslog Apr 04 10:39:04 oh there it is Apr 04 10:39:08 i thing it is some thing like ... /dev/tty.usb-serial... Apr 04 10:39:19 I don't know how ti check syslog for anything, Apr 04 10:39:25 FUN: if you have that, then you have a weird distro Apr 04 10:39:30 also dun know anything about connecting via sireal Apr 04 10:39:56 screen /dev/tty.usbX 115200 Apr 04 10:40:08 onca: there are programs called `more` and `less`, and 'tail` too Apr 04 10:40:10 whatever X is Apr 04 10:40:25 * KotH recommends picoterm instead of screen Apr 04 10:40:33 right tool for the right problem Apr 04 10:40:44 or u can use minicom Apr 04 10:40:53 minicom is too complicated for most people Apr 04 10:41:08 i use screen or minicom Apr 04 10:41:20 I know my way around linux, but alas some things are new to me Apr 04 10:41:32 how do I connect via /dev/ttyUSB0? Apr 04 10:41:36 onca: ubuntu != linux ;-) Apr 04 10:41:44 I know Apr 04 10:41:51 I use the terminal for most of my work Apr 04 10:41:59 onca: use the power of google to answer this question Apr 04 10:42:02 I've been doing this for 15 years Apr 04 10:42:17 google has led me astray, what's that called? Apr 04 10:42:25 conca: screen /dev/ttyUSB0 115200 Apr 04 10:42:31 thank you Apr 04 10:42:36 I do appreciate your help Apr 04 10:42:57 :) Apr 04 10:43:12 hello Apr 04 10:43:30 astrapotro: hi Apr 04 10:43:40 more about the ftdi usb cable problem Apr 04 10:44:42 issue? Apr 04 10:44:47 yep Apr 04 10:45:32 http://www.catb.org/esr/faqs/smart-questions.html Apr 04 10:46:37 thanks KotH Apr 04 10:46:39 KotH, that command just results in a message [Screen is terminating] Apr 04 10:47:03 onca: as i said, i think that screen is the wrong tool Apr 04 10:47:11 use at your own risk Apr 04 10:48:03 onca you could try to do an echo "some command" > /dev/ttyUSB0 to talk to the serial device Apr 04 10:48:24 onca: screen is terminating because it cann't communicate with that port Apr 04 10:48:29 astrapotro: that does not really work Apr 04 10:48:40 yes it does Apr 04 10:49:00 thank you FUN Apr 04 10:49:07 well i've tried and it worked Apr 04 10:49:29 onca: how many ttyUSB do you see? Apr 04 10:49:36 just the one Apr 04 10:51:21 astrapotro: then you set the baudrte, parity and stop bits using a different prog beforehand Apr 04 10:52:21 yes that's is Apr 04 10:53:23 that is a very important information, which you should tell an obvious n00b Apr 04 10:53:27 ubuntu gets to equal linux, because I had a system failure and put the ssd from my main machine into a netbook and it booted beautifully with gfx acceleration Apr 04 10:54:30 onca: u need to use "sudo" Apr 04 10:54:48 oh... Apr 04 10:54:48 onca: sudo screen /dev/ttyUSB0 115200 Apr 04 10:55:08 onca: adduser youruser dial-up Apr 04 10:55:11 onca: then log in again Apr 04 10:55:23 okay I will Apr 04 10:55:25 then it works w/o being root Apr 04 10:55:27 thank you Apr 04 10:56:46 onca: :) Apr 04 10:57:34 onca: er.. group is dialout Apr 04 10:57:41 not dial-up Apr 04 10:57:46 I found it Apr 04 10:57:54 screen shows nothing Apr 04 10:58:02 have you tried picocom? Apr 04 10:58:08 reset bb Apr 04 10:58:14 ah.. yes Apr 04 10:58:19 what FUN said Apr 04 10:58:28 oh wow Apr 04 10:58:33 this is fun Apr 04 10:58:44 it gets a kernel panic Apr 04 10:59:04 it's a start Apr 04 10:59:09 it says unable to mount root Apr 04 10:59:14 unknown block Apr 04 10:59:33 then your archlinux image is broken Apr 04 10:59:47 or kernel driver sdcard missing Apr 04 11:00:22 drat Apr 04 11:00:34 try debian on bb? Apr 04 11:00:41 I will. Apr 04 11:00:43 thank you Apr 04 11:00:53 should it still be ext4 ? Apr 04 11:01:49 that's filesystem, not block device Apr 04 11:02:11 okay Apr 04 11:02:16 soo, yes Apr 04 11:02:51 the official debian for bb use ext3 i think, but use ext4 if u can Apr 04 11:03:05 doesnt really matter for sdcards Apr 04 11:03:38 mine still use ext3 Apr 04 11:03:50 don't think you really wanna use journalling on sd .. certainly noatime is good :) Apr 04 11:04:01 because that's what's in the image Apr 04 11:04:03 though jury is out on that :) Apr 04 11:04:13 veremit: journaling is not much of a problem Apr 04 11:04:21 veremit: the amount of data written there is small Apr 04 11:04:39 KotH .. thats usually the problem :) Apr 04 11:04:46 nope Apr 04 11:04:54 you have wear leveling Apr 04 11:04:56 depends on ya card though Apr 04 11:05:05 some much worse than others for accesses Apr 04 11:05:09 well, cheap chinese cards are cheap chinese cards Apr 04 11:05:22 there's an alternative?! :p Apr 04 11:05:25 stick with a brand if you want reliability Apr 04 11:05:27 lol Apr 04 11:05:30 yea Apr 04 11:05:35 or buy industrial sd cards with SLC memory Apr 04 11:05:43 better the devil you know lol :) Apr 04 11:06:00 or you can pay me lots of money and i design you an sd card that never fails Apr 04 11:15:12 everytime I take the sd card out and try to mount it, /dev/sdb2 is corrupt Apr 04 11:15:25 I have an 8gb one, I shall try Apr 04 11:18:14 So i've read the datasheet of the ftdi 485 cable and i've to try to put an pull up resistor (750 Ohm) (Vcc with data+) and pull down resistor (750 Ohm) (ground with data-), to avoid z states. Apr 04 11:18:16 Then i will try to put a resistor of 120 Ohms between the data+ and data- at the end of the cable to avoid signal reflections. Apr 04 11:18:18 Is this approach correct to, maybe, solve the ftdi usb-serial hang? Apr 04 11:19:05 astrapotro: i doubt it's that Apr 04 11:19:19 astrapotro: as we have told you before, it's either a power supply issue or a driver issue Apr 04 11:19:32 astrapotro: have you ruled out both of these? Apr 04 11:21:38 ftdi uarts are very reliable Apr 04 11:22:08 no yet. We've a 2A self-powered usb hub and we power the bbb trought and usb-miniusb cable Apr 04 11:23:00 power BBB through the DC jack .. usb is only designed for 500mA .. hence 4 port hubs require 2A total. Apr 04 11:23:50 although, yea, there are exceptions .. thats the spec. Apr 04 11:25:48 spec: n. document that everyone referes to, but nobody reads. never used to design any device. Apr 04 11:26:46 shhhh :p Apr 04 11:27:38 lets not make the problem Worse eh?! :p Apr 04 11:27:56 it can't be worse Apr 04 11:29:32 xDD Apr 04 11:34:22 I bought a belken powered usb hub, unfortunatly the hub didnt work right but it had a nice 2.5 amp 5volt power supply. And its now powering the beagle happily... Apr 04 11:35:11 i think it was worth the 14 bucks even if the hub was junk... Apr 04 11:38:08 I have a usb cdrom that beagle wont drive on its own, powered hub is necessity Apr 04 11:44:17 i 've tested our installation with a raspberrypi and raspbian has solved the ftdi cable issue just a week ago Apr 04 11:44:37 so i think is something with the driver Apr 04 11:44:56 not a power problem i think Apr 04 11:51:52 thanks guys , now is time for eat something ! Apr 04 11:52:20 astrapotro: hint: rpi and bbb have different hardware Apr 04 11:55:04 KotH: really? i thought RPi and BBB were identical in every single way ;) Apr 04 11:55:28 surely if something works on one... it will always work on the other exactly the same way Apr 04 11:55:43 * Dan1 puts on flame suit and ducks Apr 04 11:55:54 * veremit lights the torch .. Apr 04 11:55:59 lol Apr 04 11:56:15 i mean.... there almost the SAME SIZE!!! Apr 04 11:56:20 surely that means something Apr 04 11:56:22 coulda sworn I said someting about not makin things WORSE .. damnit! :p Apr 04 11:56:31 lol Apr 04 11:56:35 looool Apr 04 11:56:41 * KotH hands veremit a pitchfork Apr 04 11:56:46 hahaha Apr 04 11:56:48 :D Apr 04 11:56:53 ah thanks .. just wha tI needed Apr 04 11:57:12 now all I need is a cute farmgirl ... Apr 04 11:57:16 >,< Apr 04 11:58:10 in a tucker & dale v evil sorta way?? Apr 04 12:01:28 hey, so I finally got the beagle bone to boot but it doesn't get an ip address Apr 04 12:01:48 I know it loads now, I'm not sure what's the problem Apr 04 12:02:53 usb gadget ethernet or plain old conventional rj45? Apr 04 12:03:13 can u log in to bb using usb-serial? Apr 04 12:06:02 * Dan1 wonders if anyone has coined the term "PEBBBAC" yet? Apr 04 12:09:34 Dan1: no, but PEBBBBAC is already in heavy use Apr 04 12:10:28 KotH: hmm.... has the stoopids increased with the bbb? that didnt exist in teh days of the more expensive bb's? Apr 04 12:11:23 yes, the number of i-dont-know-how-to-spell-linax is o(e^-price) Apr 04 12:11:58 hahaha ahh Apr 04 12:12:45 sadly... i came from RPi and moved to BBB... but im lucky enough to have some fairly knowledgeable linux people around me Apr 04 12:13:18 so i already knew id need to learn a heap before i got anything to do what i wanted Apr 04 12:14:08 well.. i dont mind people who are new to linux (or stuff in general) Apr 04 12:14:33 but i mind people who don't want to see that they have to learn a lot of stuff if they want to use something complex Apr 04 12:14:58 oh yea Apr 04 12:15:07 ive delt with them in other walks of life Apr 04 12:15:12 sadly, modern linux distros have become good windows emulators... including teaching people that they dont need to know anything of what is going on underneath Apr 04 12:15:15 its not only an IT thing Apr 04 12:15:26 yup Apr 04 12:15:38 yeah... drawing red lines with blue ink Apr 04 12:15:48 tho.... it is what got me into linux after MANY decades of windows and other things Apr 04 12:17:11 I jumped into linux right after blue screen of death on xp Apr 04 12:17:20 loool Apr 04 12:17:34 it Apr 04 12:18:07 it's the driver causing the problems and I can't fit it Apr 04 12:18:34 bad 'VAIO' Apr 04 12:19:20 the intel wifi chip also died Apr 04 12:19:40 partially... Apr 04 12:20:08 then linux saved my year! Apr 04 12:20:36 it was good for high school homework :) Apr 04 12:20:45 welcome to the light Apr 04 12:20:59 we accept all kind of students and converts here ;) Apr 04 12:24:02 ok tis time for an afk session .. bbl :) Apr 04 12:45:41 so anyone has proved an ftdi usb-serial cable without any issues? Apr 04 12:46:36 i can't prove, but it works for me Apr 04 13:35:04 what's the default root password for the debian package Apr 04 13:35:59 root/nothing Apr 04 13:36:43 just hit enter? Apr 04 13:36:55 oh Apr 04 13:37:05 if official bbb debian then Apr 04 13:37:15 debian Apr 04 13:37:19 temppwd Apr 04 13:37:31 id: debian, password:temppwd Apr 04 13:37:55 FUN no? my debian was just root/nothing Apr 04 13:37:56 ? Apr 04 13:38:42 if u want to log in as root, there is no password, but if u want to log in as user, then {debian:temppwd} Apr 04 13:39:14 oh, yer ok i only loged in as root and set up a new used Apr 04 13:39:23 *user Apr 04 14:26:48 anybody knows why https://rcn-ee.net/deb/rootfs/wheezy/debian-7.4-console-armhf-2014-03-27.tar.xz this image without any changes the wifi dongle doent work? Apr 04 14:26:54 on BBB Apr 04 14:28:38 [A Apr 04 14:29:16 agmlego:? Apr 04 14:29:27 Sorry, client lag. Apr 04 14:29:56 salaet: My guess is your WiFi dongle does not work because the image that you are using does not have the driver installed on it for your WiFi dongle. Apr 04 14:30:07 So find out which driver you need, and install the driver. Apr 04 14:30:31 agmlego:but lsusb doesnt detect Apr 04 14:30:51 root@beaglebone:~# lsusb Apr 04 14:30:52 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Apr 04 14:30:54 Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Apr 04 14:30:59 nothing more Apr 04 14:31:08 and UWN200 is connected Apr 04 14:31:13 OK, so maybe you are not providing the unit with enough power to turn on fully and enumerate. What does dmesg say? Apr 04 14:32:26 http://pastebin.com/CVhVrcTD Apr 04 14:32:35 its 5V 2A Apr 04 14:33:21 It's the last image Apr 04 14:36:41 Right, but you have the WiFi dongle plugged into a powered hub, right? Apr 04 14:37:03 The bone generally has trouble providing sufficient power out the USB port for high-power devices. Apr 04 14:38:51 but with other version of debian I'm going back with sd Wifi dongle works Apr 04 14:39:52 Then figure out the difference between the two images. Apr 04 14:40:17 Again, check dmesg to see what happens when you plug in the dongle. I suspect you do not have the correct module loaded. Apr 04 14:42:34 when you refer a module ? are you saying to install drivers? Apr 04 14:42:47 ...yes. Apr 04 14:42:50 UWN200 it's supported , no? Apr 04 14:43:16 Linux calls drivers modules, because the kernel is a modular one. You load only the modules you need for the hardware you have. Apr 04 14:43:21 I have no idea, is it? Apr 04 14:43:38 Check the list of supported chipsets on the debian armhf project. Apr 04 14:43:54 Or, find the open-source driver for it and compile the module against your kernel. Apr 04 14:44:41 agmlego: If I can run wifi and minimal , without node,apache,X windows etc.. I'm very happy Apr 04 14:45:20 OK. SO do that then. Apr 04 14:45:37 Or, uninstall the things you do not need from the working image. Apr 04 14:45:56 But I suspect it will be easier just to get the correct module installed. Apr 04 14:50:02 Installed like https://docs.google.com/a/logicsupply.com/document/d/1-CIGQYdk8ZhU3D3UCNn70jc7C9HdXvEZAsiNW71fGIE/edit?pli=1#heading=h.k9hc7n9nppyo Apr 04 14:50:10 not work Apr 04 14:50:24 I rollback to image Apr 04 14:51:15 salaet: On *both* images, the working one and the non-working one, I need you to do a few steps for me. Apr 04 14:51:52 1. run lsmod to show the list of loaded modules. There should be at least one more present on the working one than the non-working one. Apr 04 14:52:26 ok Apr 04 14:52:31 root@beaglebone:~# lsmod Apr 04 14:52:32 2. read dmesg on both systems when you plug in the dongle. Pastebin only the part of dmesg that pertains to when you plugged in the dongle. Apr 04 14:52:33 Module Size Used by Apr 04 14:52:34 g_multi 47670 2 Apr 04 14:52:36 libcomposite 14299 1 g_multi Apr 04 14:52:37 no working Apr 04 14:52:39 salaet: PASTEBIN Apr 04 14:52:43 ok! Apr 04 14:52:45 sorry Apr 04 14:52:52 go to flash the image Apr 04 15:34:24 http://pastebin.com/SsSa2R2B Apr 04 15:34:34 this is without running wifi Apr 04 15:35:37 agmlego: this is with module wifi loaded but not run , I go 2 versions back now Apr 04 15:35:38 http://pastebin.com/ Apr 04 15:35:40 sorry Apr 04 15:35:59 http://pastebin.com/jTCdnBd9 Apr 04 15:37:40 mt7601Usta is the WiFi module. Apr 04 15:38:12 but not run Apr 04 15:38:13 Looks like on your non-working image, the USB subsystem cannot assign an address to the dongle, probably because you are missing the driver. Apr 04 15:38:39 I'm get now from here http://elinux.org/BeagleBoardDebian Apr 04 15:38:46 and flash to beaglebone Apr 04 15:38:55 Sure. Apr 04 15:39:56 but this image I got from http://beagleboard.org/latest-images Apr 04 15:41:25 the non working image is from http://beagleboard.org/latest-images Apr 04 15:41:29 the wifi Apr 04 15:42:53 Lunch time. Apr 04 15:52:58 agmlego:In catalonia we said , Bon profit Apr 04 17:42:41 What's the change to the rev c Apr 04 17:43:25 Bigger eMMC. Apr 04 17:43:36 And a bunch of things, all listed on the revision sheet. Apr 04 17:58:56 how much of ram would a am335x be able to handle ? Apr 04 17:59:47 rob_w: sounds like a great question for the TRM Apr 04 18:00:28 rob_w: http://www.ti.com/product/am3359 Apr 04 18:01:10 ah now i see it Apr 04 18:01:12 thx Apr 04 18:01:22 1GB of Total Addressable Space Apr 04 18:01:41 Not sure that's the same thing Apr 04 18:02:34 np i was just wondering .. not desging anything else then 512 atm Apr 04 18:46:03 is the circuitco.com wiki down for other folks? Apr 04 18:51:49 no Apr 04 18:52:25 oh wait looks like its broken.. lol Apr 04 18:58:26 anyone have a bbb sch handy? Apr 04 18:58:57 its on elinux.org no ? Apr 04 18:59:05 thats up .. just checked it too :p Apr 04 19:00:36 pthomas__: there shouldn't be any more circuitco wiki Apr 04 19:00:39 short answer is no Apr 04 19:00:45 pthomas__: what url are you trying toa ccess?

Apr 04 19:52:28 pthomas__: all links to circuitco support should be redirected to elinux.org Apr 04 19:52:30 I am having a problem with spi_omap2_mcspi module using one ethernet adapter connected to spi1. Apr 04 19:53:01 here is the message: NETDEV WATCHDOG: eth1 (enc28j60): transmit queue 0 timed out Apr 04 19:53:34 Have someone any experience with this problem before? Apr 04 19:54:04 Ventura: either there is an issue with the setup of your pinmux or the enc28j60 was stuck waiting for an irq to be serviced Apr 04 19:54:49 all the links on the main beagle board page Apr 04 19:54:50 http://beagleboard.org/Products/BeagleBone+Black Apr 04 19:55:03 and then in the maual the links are to circuitco Apr 04 19:55:22 Ok, but what I observed is if I force the drive to use only DMA everything works but when I mix DMA with PIO I get this problem... Apr 04 19:56:03 I'm not sure you wanna mix pio with dma Apr 04 19:56:35 The drive does that, if the buffer size < 160; goes to PIO... Apr 04 19:57:03 It's supposed to have better performance... Apr 04 19:57:34 I have to ask .. why using SPI ethernet!? Apr 04 19:58:29 This is the cape that I have; It's connecting one microchip enc28j60 ethernet using spi as the interface to beaglebone. Apr 04 19:58:51 how many ports do you need?! Apr 04 19:59:06 why not just get a vlan capable hub chip instead Apr 04 19:59:19 One SPI and one GPIO pin for interrupt... Apr 04 19:59:21 run dot1q Apr 04 19:59:43 what is dot1q? Apr 04 20:00:08 pthomas__: all of those links should redirect to elinux.org Apr 04 20:00:13 pthomas__: i'll check on that Apr 04 20:01:01 ieee802.1q Apr 04 20:01:58 Sorry, I think that I mixed in another chat.. Apr 04 20:06:05 pthomas__: yep, looks like there was some broken php, it's fixed now, thanks for calling attention to the issue Apr 04 20:06:49 The routine that is issuing the NETDEV WATCHDOG is dev_watchdog. I think that for any reason the PIO is not dispatching the buffer causing this problem... Apr 04 20:07:25 so why the switch to elinux? that's digikey's site right? Apr 04 20:07:34 When I use DMA only, the mechanism is totally different and it works... Apr 04 20:07:53 pthomas__: no Apr 04 20:07:53 Ventura .. need to dig deeper into the driver I suggest Apr 04 20:08:14 elinux is a community site I thought Apr 04 20:08:18 pthomas__: elinux.org is an embedded linux wiki that is sponsored by the linux foundation Apr 04 20:08:37 oh cool Apr 04 20:08:54 Yes, you are right. I just try here before because most of the time I get something. I'm gonna do that... Apr 04 20:08:59 pthomas__: it made sense that instead of having circuitco host a dedicated wiki, that it should be hosted on a community site such as elinux.org that has other links and materials for embedded linux Apr 04 20:36:10 802.11.1q Apr 04 20:36:16 802.1q I mean blah Apr 04 20:36:41 yeah one of them thingies :) Apr 04 20:37:04 spi ethernet gotta be almost as bad as the usb ethernet on pi Apr 04 20:52:11 veremit: SPI ethernet works great for what it was designed for Apr 04 20:52:28 veremit: just like anything else, you use it for something it wasn't intended, you are likely to be disappointed Apr 04 20:52:34 that applies to many things :) Apr 04 20:52:38 indeed Apr 04 20:53:36 not that there's anything wrong with sticking bits together with electronic glue because you can .. Apr 04 21:06:36 veremit: indeed Apr 04 21:06:45 veremit: i've used the enc28j60 a time or two Apr 04 21:07:02 I've got a couple .. but then I acquired my beagle and wand .. lol Apr 04 21:07:16 hardware ethernet <3 Apr 04 21:07:40 onboard wifi <333 Apr 04 21:44:47 <_ssl> hello #beagle! i have booted from an sd card on my BBB with the newest ubuntu image i got from here: http://elinux.org/BeagleBoardUbuntu#raw_microSD_img now i wanted to try continuous ADC sampling mode, like explained here: http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide#How_to_set_it_up but i find there is no "mode" file in the specified folder. what am i doing wrong? Apr 04 21:46:09 <_ssl> that TI page is telling me that "Please note that continuous mode is only supported with the v3.2_AM335xPSP_04.06.00.10-rc1 release or later" but i dont even know what they are talking about here? is that a kernel version?! Apr 04 21:46:13 I would imagine you need to build/configure a driver Apr 04 21:46:28 <_ssl> my uname -a outputs Linux arm 3.8.13-bone40 #1 SMP Fri Jan 31 10:36:05 UTC 2014 armv7l armv7l armv7l GNU/Linux Apr 04 21:46:45 yes the TI PSP is a package with kernel/rootfs/etc Apr 04 21:47:44 <_ssl> so i can't use continuous sampling with the ubuntu image from elinux.org? Apr 04 21:48:06 not out-of-the-box no .. but it shouldn't be impossible Apr 04 21:49:06 3.2...PSP is a kernel from TI Apr 04 21:49:19 it's the 3.2 kernel with all kinds of stuff merged on top of it Apr 04 21:49:43 Newer beaglebone stuff uses kernels that are closer to mainline. Nowdays mainlie + just a few patches. Apr 04 21:50:17 The PSP kernels have features that are not upstream (mainline), and sometimes they do the same things but in a different way Apr 04 21:50:27 unfortunately a lot of documentation refers to the older stuff :( Apr 04 21:50:55 <_ssl> i'm sorry i'm not into kernel thingies. what i really want it ADC continuous sampling on the BBB, i dont really care about the operating system, since i have to write my software bottom up anyways. Apr 04 21:51:27 http://eewiki.net/display/linuxonarm/BeagleBone+Black Apr 04 21:51:31 <_ssl> so what would be the best/easiest way to achive that? Apr 04 21:52:08 look for the driver-specific options as per the TI app note Apr 04 21:52:20 as soon as te kernel config comes up Apr 04 21:53:48 I think on the newer kernels stuff like ADC is handled through IIO Apr 04 21:55:06 <_ssl> alan_o i think you are right, i found this blog here which seems to be just what i want, but unfortunatly, the author seems to have discontinued it http://beagleboard-gsoc13.blogspot.de/ Apr 04 21:55:59 looks like that was from GSOC last year Apr 04 21:56:07 <_ssl> veremit: sorry i dont understand. do you propose for me to manually install the OS with another kernel? Apr 04 21:56:44 you're most likely going to need a different kernel, yes Apr 04 21:57:02 robert nelsons's site walks you through it quite painlessly Apr 04 21:57:10 <_ssl> alan_o yes, i think he made some changes to the (mainline?!) kernel to include the continuous sampling with iio, but i dont know how i can get it to work for me Apr 04 21:57:44 wonder where the man himself has gone .. he used to visit here ... Apr 04 21:58:31 looks like you read stuff from /sys/devices/ocp.*/ but I'm not seeing that on my installation (but I'm running full mainline 3.14) Apr 04 21:58:51 3.14 now?! Apr 04 21:59:05 3.14 was released a few days ago Apr 04 21:59:14 there's a build for beagle/ Apr 04 21:59:14 but the beagleboard.org kernel is using 3.13 still Apr 04 21:59:37
