**** BEGIN LOGGING AT Thu Jan 15 03:00:00 2015 Jan 15 11:12:19 hi, anyone from the BeagleBone dev team present? Jan 15 11:27:45 Hi, Can we use the default u-boot in eMMC to boot kernel from SD card by overriding bootcmd in uEnv.txt? I am using BB-black. Jan 15 11:34:35 shaz: it will boot on the sd card if there is no bootloader on the eMMC Jan 15 11:34:51 don't know if this is a solution for you Jan 15 12:02:33 does anyone know who i should ping to get a hold of a BB dev? Jan 15 12:03:23 just ask your question here Jan 15 12:03:38 somebody will answer it when they see it Jan 15 12:10:07 julemand101: I know of this option but I was of the opinion that if we edit uEnv.txt than maybe we could leave the eMMc undisturbed. Jan 15 12:10:40 I heard a rumor of a new BB, so i wanted tto ask http://ikmaak.nl/eenblog/2015/01/15/beaglebone-green/ Jan 15 12:12:24 julemand101: Something like: bootcmd=mmc rescan ; fatload mmc 0 0x80008000 kernel-bin in uEnv.txt Jan 15 12:16:38 ruben-ikmaak: maybe they are bb certified, like the element14 beagles. just an assumption :) Jan 15 12:16:52 still it sounds cool Jan 15 12:17:04 and it looked like an announcement to me... Jan 15 12:19:38 When I run from cloud9 I get a message Jan 15 12:19:41 Starting PHP built-in web server, serving https://undefined/Support/BoneScript/demo_oscilliscope.html. Jan 15 12:20:00 Where might I define 'undefined' ? Jan 15 12:20:32 ruben-ikmaak: BBB is OSHW, so seedstudio can go and spin their own board, calling it beaglebone would have certain implications as that's a trade mark IIUC Jan 15 12:20:50 ruben-ikmaak: there is a compliance requirement for the latter, check the bb.org page Jan 15 12:21:09 also, isnt the element14 thing just the same board, and this one is different design Jan 15 12:21:28 there is zero information beyond what you posted, so hard to say Jan 15 12:21:36 there is the beaglebone compliant for the element Jan 15 12:21:59 the element14 is a 100% clone and compliant. Jan 15 12:22:09 well, if they have a design that adds hardwareports, that should change the board layout Jan 15 12:22:35 as said, it's OSHW and they can do whatever they want Jan 15 12:22:56 so if they would indeed alter the design, they would have a harder time to be BBcompliant Jan 15 12:22:59 and it needs zero input/approval from the entity behind bb.org Jan 15 12:23:21 it only matters if they want to be compliant or such Jan 15 12:23:25 that is why i was talking about codename Jan 15 12:23:55 they could call it bb alike or such Jan 15 12:24:06 bascially what I'm trying to say is, you won't get answers here Jan 15 12:24:10 and just call it the SeeedBone Jan 15 12:24:39 if there was a dev here, i could ask him if someone contacted them Jan 15 12:25:09 that was the reason for my initial q Jan 15 12:26:43 try asking on the ML and don't ask for "devs" as those people don't call themselves such. Jan 15 12:27:07 how would they describe themselves? Jan 15 12:27:09 or go through the proper contact channels. I bet those are outlined on the bb.org page Jan 15 12:28:54 ok, i'm looking Jan 15 12:29:30 I wonder if the 'undefined' is in a cloud9 runner config, or some external config in say /etc/xxx Jan 15 12:46:09 Setting bootdelay=-1 gives gives uboot shell which is equally useful. Lets try bootcmd now. Jan 15 12:46:58 It should be possible to load kernel or uboot from this uboot shell. Jan 15 12:55:10 Uboot is checking for uSD so it means kernel can be loaded from it. So just have to try and hit the right commands with right parameters. Jan 15 12:57:27 you can have MLO/U-boot on emmc and boot from sd, sure Jan 15 12:57:34 Is there a way to get a more verbose log when running from cloud9 ide? Jan 15 13:07:08 GumShoe: check the cloud9 systemd service on the board Jan 15 13:07:15 maybe it has an output file for logging Jan 15 13:07:52 tbr: looking for the right command to get non-linix kernel loaded. Jan 15 13:08:25 tbr: Something like: bootcmd=mmc rescan ; fatload mmc 0 0x80008000 kernel-bin in uEnv.txt Jan 15 13:23:46 shaz: no idea, I'm not a u-boot person Jan 15 13:26:16 tbr: What else do u specialize in apart from serial adapter? Jan 15 13:35:00 yup the above command is correct ... just need to verify the addresses and be able to make sure serial console is handled correctly by kernel Jan 15 14:18:29 the interesting part is that when I inserted a sd card the boot sequence automatically switches to it. This is not documented as far as I googled. No need to hold boot button. Jan 15 14:20:21 uboot cannot find uEnv.txt on sd card. SD card even is'nt formated at the moment. This is a nice behavior. Jan 15 14:20:46 if sd card is present then uboot will load boot environment according to it. Jan 15 14:53:38 51 Jan 15 14:53:42 whoops, sorrt Jan 15 15:17:40 Morning all. Jan 15 15:21:51 Got a question - i have a bbb element14 running debian. I recently noticed my logs were filled with intrusion attempts so i changed the port, enabled RSA logins, disabled root logins, and disabled password logins. SSH is working on 4 of my 5 devices but for some reason attempting to connect with the 5th keeps getting "Connection refused" despite having put the key in "authorized_keys". I also checked to ensure the ip hasn't been Jan 15 15:28:33 some news about the X15 ? Jan 15 15:33:08 Rangergeek: sounds like more of a debian issue Jan 15 15:33:49 Rangergeek: if you are security conscious, I'd recommend to check if you have the weird e14 debian version or the proper RCNee beagleboard.org version running, as an aside. Jan 15 15:36:56 hello Jan 15 15:48:49 tbr: thanks for the response. I actually JUST got it figured out. It appears my work network is now blocking those connections as I couldn't even ping 8.8.8.8 (google). I connected to my vpn and things are working as expected. I will check into the debian versions. :) Jan 15 15:51:13 :) Jan 15 16:34:39 Maybe someone else will know here. So I was originally a raspberry_pi guy but switched to beaglebone for a little better power and i/o with what I want to do. So I got a BBB and it seemed there was some power management issues with handling my wifi dongle. I thought maybe i wasn't getting enough power but my adapter was 2a and i was usiing a 5v 2a wall plugin and had also tried a 5v 2a portable battery. Jan 15 16:35:02 you'll need a powered hub Jan 15 16:35:17 it won't run from the beagle on its own Jan 15 16:35:27 I originally tried a micro, but thought maybe a barrel connector would be better so I got that, and same result. Using a multimeter it seemed like the wifi dongle was only getting ~ .2A :( Jan 15 16:35:32 so you'll need 2 power adapters .. one for beagle & one for hub Jan 15 16:35:48 Well the goal was that I could make it portable like I had on my pis. Jan 15 16:36:11 Is it just that the beaglebone is more power-hungry and can't support its peripherals as well? Jan 15 16:36:32 its just a known trick. I don't think the beagle usb port is designed for "high power" peripherals Jan 15 16:36:54 on the pi, its already supplied by a hub chip.. so .. :) Jan 15 16:37:28 Ahh, that must be why. I wish they'd create a more portable-friendly version of the bone then. :) Jan 15 16:39:08 there are evaluation boards for the am335x processor, but you'er talking $100 not $30 .. :) Jan 15 16:39:40 alternatively, if you want a wifi arm board .. I recommend the wandboard dual-core .. its a bit more expensive, but you got it all onboard :) Jan 15 16:41:04 it also takes away a moderate amount of the driver headaches that cheap wifi sticks cause too Jan 15 16:51:28 stt_michael: is the am335x EVM *that* cheap? Jan 15 16:51:52 ah no, didn't think so... TMDXEVM3358 ... $995 Jan 15 16:53:04 ok I missed a 0 :) Jan 15 16:53:27 just trying ot illustrate a price difference ... Jan 15 16:54:40 the ICE is a lot cheaper, $189 Jan 15 16:55:00 what's that? Jan 15 16:55:31 http://www.ti.com/tool/tmdsice3359 Jan 15 16:58:19 there are actually a lot of am335x eval boards it seems... starterkit ($199 http://www.ti.com/tool/tmdssk3358) has saner connectivity and an LCD touchscreen Jan 15 17:00:21 hmm I like the dual ethernet .. ideal for router boards :D Jan 15 17:00:47 still, I don't see an obvious reason why the BBB wouldn't be able to source power via usb, it's fed from the SYS_5V through a power switch IC Jan 15 17:01:39 designed for 0.5A Jan 15 17:02:25 stt_michael: does the dongle just "not work" or does it take down the BBB ? Jan 15 17:02:52 (the latter indicating the SYS_5V is the limiting factor) Jan 15 17:03:08 technically, they work . but they're not reliable from all the reports I've read and official statements Jan 15 17:03:31 I think you'll probably find many usb wifi dongles are outside the 0.5A 'spec' of USB Jan 15 17:03:42 and I suspect the pmic doesn't quite fully support that 0.5a anyhow Jan 15 17:03:53 But .. I could be wrong :) Jan 15 17:04:50 the power switch I'm referring to is not the PMIC btw but "U8" (TPS2051) Jan 15 17:06:01 ah a 2051 .. should be ok then :D Jan 15 17:06:11 the pmic supports 2A iirc Jan 15 17:06:13 iirc .. used similar to those for usb before Jan 15 17:06:15 but that's for the whole board Jan 15 17:06:23 yes Jan 15 17:06:33 that's why I was wondering if you were taking down the SYS_5V Jan 15 17:06:48 if so, better power management of the AM335x and peripherals may free up power for USB Jan 15 17:07:01 I haven't done any testing with wifi .. I just use a RJ45 .. works perfect for me ;D Jan 15 17:07:05 or my wand Jan 15 17:07:18 ah sorry my questions should have been directed as Rangergeek Jan 15 17:07:23 *at Jan 15 17:07:33 people keep wanting the moon on a stick with the beagle/pi .. and its friggin $20-30 !! Jan 15 17:07:56 its like trying to run windows on an arduino .. *mutters* ok enough on the soapbox lol Jan 15 17:08:04 hehehe Jan 15 17:08:22 I don't like the pi .. but my beagle is fine for what I need it for Jan 15 17:08:42 and I love my wands :) sound+wifi all on board .. no usb danglies or anything Jan 15 17:08:50 Just Works. Jan 15 17:09:09 all from 5V @ 2A ;) Jan 15 17:09:37 rpi... sucky broadcom chip, armv6 architecture, barely any docs, errata maintained on a wiki since broadcom doesn't publish any, i2c very broken... wonderful place ;) Jan 15 17:10:06 only reason I might be interested in one is because the rpi allows you to experiment with trustzone, it boots up in secure mode Jan 15 17:10:21 while TI annoyingly has ROM lock the place up and throw away the key Jan 15 17:10:59 just can't win eh!? lol Jan 15 17:11:35 but ye .. they totally missed the point with the Pi .. ok so Eben achieved his key aim .. but missed so many opportunities for creating something totally revolutionary, its not funny. Jan 15 17:11:47 I will hand it to him for starting the ball rolling with low-cost arm though. Jan 15 17:11:54 (still need to try to exploit the second potential hole in secrom, the first one just led to a pissed-off Secure State Machine hitting the internal "MPU Security Violation" reset) Jan 15 17:12:04 oops :/ Jan 15 17:13:32 putting the secure-world MMU tables in publicly accessible RAM didn't seem too bright, but the addresses for entry into secure monitor mode is heavily double-checked by the grumpy SSM, so basically you can just freely choose the cache-policy for that MMU entry but that's all Jan 15 17:13:49 over my head lol Jan 15 17:14:30 still need to do some tests how much performance benefit you gain from unlocking the TLB entries locked by secrom though Jan 15 17:16:04 well i can't officially recommend it Jan 15 17:16:12 the processor has only 32 entries on data side and 32 on instruction side... if software accesses a page that's not one of the last 32 pages you get a TLB miss Jan 15 17:16:25 TLB miss penalty is 24 cycles absolute minimum, more in reality Jan 15 17:16:30 but you can use some jumper wires to power the BBB and usb device direclty from your power supply Jan 15 17:16:42 locking two out of those 32 entries is pretty awful wasteful Jan 15 17:17:05 johnwalkr: powering via the battery terminals rather than the DC plug should also help, according to the PMIC's datasheet Jan 15 17:17:15 but you lose overvoltage protection Jan 15 17:17:50 yeah which is not a big deal if you are just using one device and leaving it there Jan 15 17:18:07 that feature of usb is more because shorts are likely when you are hot plugging stuff all of the time Jan 15 17:19:04 you're assuming the usb power switch is the limiting factor, that doesn't seem to be the case Jan 15 17:19:49 since Rangergeek measured about 200 mA being supplied while the usb power switch can supply 500 mA Jan 15 17:20:02 if SYS_5V can deliver Jan 15 17:20:13 no i think i just realized we're not quite on the same page though.. Jan 15 17:21:39 in my case i have a 5V supply powering the BBB, and teh same supply goes directly to my usb device, which is not connected to the BBB, it's connected directly to the power supply. Jan 15 17:21:48 i.e. from before the pmic Jan 15 17:22:28 yeah I understand, but that's a bit more radical and as you said you lose overcurrent protection Jan 15 17:22:42 even though it's not the overcurrent protection that's causing the limitation here apparently Jan 15 17:23:25 I think the issue is more likely a peak/trough which won't be apparent from a steady-state 200mA current reading Jan 15 17:23:36 it needs some serious oscilloscope and current probe testing I feel Jan 15 17:23:54 might help, although there are fat capacitors in many places obviously Jan 15 17:24:20 yeah i understand that but something in the system is limiting apparently. anyway a hub is a safe and easy way to get around that without drastic measures or lots of troubleshooting Jan 15 17:24:59 measuring SYS_5V voltage would be helpful to identify the root cause Jan 15 17:25:38 but, it stopped raining I think so time to do some shopping Jan 15 17:26:21 lol Jan 15 17:26:25 have fun Jan 15 17:29:22 really glad i picked the BBB for my project these days. so many other options but they all have some weird closed part. working on a board with 2x am335x and direct camera interfaces and canbus Jan 15 17:30:43 also temped to start with odroid-w though even though they aren't making any more. Jan 15 17:53:35 Good morning fellas, has anyone tried audio out on kernel 3.17+? Jan 15 18:11:51 zmatt - I do appreciate the response and the talking between youa nd stt_michael. :) I finally got caught up. (I'm at work) stt_michael is correct. When the USB dongle is plugged in it fails but the beaglebone remains functional. Jan 15 18:15:11 they've discontinued the odroid w already? Jan 15 18:21:50 yes Jan 15 18:22:15 as i understand it they are not allowed to buy that cpu anymore Jan 15 18:22:34 but that tiny package including camera interface is really nice Jan 15 18:47:37 hi guys Jan 15 18:47:59 can anyone tell me if I can boot a beagleboard using ltsp? Jan 15 18:48:14 (dhcp + tftpd) Jan 15 18:49:36 beaglenewby: it's possible, sure Jan 15 18:49:54 i am currently doing that on raspberry pi using berryterminal distribution Jan 15 18:50:10 but its responsiveness is too slow for heavy internet and office use Jan 15 18:50:27 * vagrantc prefers to actually use LTSP over berryterminal, but that's perhaps biased Jan 15 18:51:21 what do you mean vagrantc Jan 15 18:51:23 beaglenewby: actually, re-reading what you asked, i've only tested on a beaglebone black Jan 15 18:51:30 has anyone tried audio out on kernel 3.17+? Jan 15 18:51:32 because berryterminal is to use LTSP on rasp Jan 15 18:52:03 beaglenewby: berryterminal emulates LTSP, and uses some LTSP code, but isn't actually booting using LTSP Jan 15 18:52:11 and it worked? did you had to put the kernel image on the ftp server? Jan 15 18:52:27 yeah that's the POINT that troubles me Jan 15 18:53:09 beaglenewby: yeah, tftp a boot script from u-boot, which downlods the kernel+initrd+dtb and boots it with appropriate arguments to mount the root filesystem Jan 15 18:53:10 was it easy to compile the kernel for the beagleboard architecture? Jan 15 18:53:17 cool! Jan 15 18:53:28 can you tell me if it was more responsive than berryterminal? Jan 15 18:53:39 i don't use berryterminal Jan 15 18:53:43 oh ok Jan 15 18:53:56 I suppose so because rasp spec is inferior Jan 15 18:53:56 overall, it's not likely to be hugely more responsive Jan 15 18:54:34 how many cores the bb black has? Jan 15 18:54:46 the responsiveness really depends on what you're doing Jan 15 18:55:11 the BBB has only one core Jan 15 18:55:50 its all about spreadsheets and some heavy javascript internet pages Jan 15 18:56:39 with a thin client, the speed of the client isn't typically the main limiting factor, the video graphics on the client do matter a lot, though. Jan 15 18:57:41 adam_ is you using a cape for your audio? Jan 15 18:57:43 i notice some lag on the video thats the limiting factor Jan 15 18:57:56 i dont know maybe I should try overclock the pi Jan 15 18:58:06 but that is a matter for another channel :) Jan 15 18:58:18 I hope to achive audio via the PWM usign a pieso electric speeker Jan 15 18:58:40 beaglenewby: like i said, it's probably not the processor speed that's your limiting factor, so speeding that up probably won't make a huge difference Jan 15 18:59:31 after disabeing the ssh compression things speeded up a bit Jan 15 18:59:38 disableing Jan 15 19:00:00 cityoflights2: no i have a beagleboard xm - twl4030 is part of the board Jan 15 19:00:27 aha I got the BBB Jan 15 19:00:36 beaglenewby: but unless you want to try on one of the beagleboard.org boards, probably more appropriate for #ltsp or #raspberrypi Jan 15 19:00:52 allright vagrantc Jan 15 19:01:01 thank you for your time Jan 15 19:01:15 hope to come back when trying the BBB for some projects Jan 15 19:01:54 i am starting a project to make a robot with a oled display for a remote table RPG player Jan 15 19:02:23 will be a surprise to my son so we can play with some distant friends :) Jan 15 19:03:12 like the one snowden used on his TED talk, but smaller and more humanoid like Jan 15 19:03:48 i will probably post it on instructables or something like it Jan 15 19:04:16 thank you again, bye! Jan 15 19:31:38 + Jan 15 20:22:45 I'm setting up my BBB for the first time and am running into some issues. I'm connected via usb, have network access (can ping out). However, I'm unable to either set the date and time (using either ntpdate or ntpdate-sync) or to download & install packages; I get "can't connect to remote host (140.211.169.161): Connection timed out". Jan 15 20:23:42 I've been to derekmolloy.ie and have followed the advice given there which has gotten me this far, but am now stuck. Jan 15 20:24:59 sounds very battery life friendly :D Jan 15 20:25:39 blah Jan 15 20:25:48 wrong channel Jan 15 20:26:02 Trian3: you need access to the internet or you can set it manually with the date command Jan 15 20:26:33 ds2: I have access to the internet as I can ping out just fine Jan 15 20:26:49 can you ping say...www.yahoo.com? Jan 15 20:26:58 or are you pinging just the computer? Jan 15 20:26:59 Well, google, yes. Jan 15 20:27:11 what's the error with ntpdate? Jan 15 20:27:21 and how exactly are you running it? Jan 15 20:27:31 check ipconfig, route and resolv.conf Jan 15 20:27:54 Well, that one doesn't actually return an error. It appears to work fine, but when i check the date or time afterwards, it returns the same as before. Jan 15 20:27:56 on the beagle .. and what are you using host side to redirect packets from the beagle to the internet? Jan 15 20:28:08 I'm running "ntpdate -b -s -u pool.ntp.org" Jan 15 20:28:23 And date afterwards is "Sat Jan 1 00:25:37 UTC 2000" Jan 15 20:28:34 normally, for instance, windows won't act as a router for the beagle Jan 15 20:29:10 *shrug* Jan 15 20:29:19 Right, I followed the advice on derekmolloy.ie to resolve that. Had to go into network settings (I'm on windows 7) and share (or bridge) the connection. Jan 15 20:29:28 just set it manually with date and move on :D Jan 15 20:29:46 But that won't fix my other issue (which I suspect may be related to the first) Jan 15 20:29:54 That of the packages failing to download & install. Jan 15 20:30:17 packages? Jan 15 20:30:17 hence why I suggest you look at route and resolv.conf :) Jan 15 20:30:21 yuck Jan 15 20:30:25 debian I'm guessing Jan 15 20:30:25 build it yourself :D Jan 15 20:30:36 bitbake FOOBAR Jan 15 20:30:45 eww angstrom Jan 15 20:30:54 resolv.conf has "nameserver 8.8.8.8" added already. Jan 15 20:31:46 does 'wget http://www.yahoo.com/' work? Jan 15 20:31:49 well .. if you can ping 8.8.8.8 successfully, your network route works .. and if you can ping www.google.com your name resolution works Jan 15 20:32:00 ping can be screwed with Jan 15 20:32:32 did you restart windows and/or the beagle after you set up network bridging? Jan 15 20:32:47 I've been trying to step my way through a beginner's tutorial on Adafruit's website and one of the first steps was to install Angstrom. Don't know if that was necessary, but I'm just following along... Jan 15 20:33:01 oh joy .. good luck :D Jan 15 20:33:36 When I type 'wget http://www.yahoo.com/", it appears to time out. Still says "Connecting to www.yahoo.com" Jan 15 20:34:00 I haven't restarted windows since bridging network, no. Jan 15 20:34:17 Everytime I do restart, I have to reset that all up again as the settings don't appear to hold. Jan 15 20:34:27 smells like your beagle isn't resolving network names ie. dns Jan 15 20:34:44 yet I can ping www.google.com Jan 15 20:34:50 that also smells like windows bein crap lol Jan 15 20:35:18 which could cause all sorts of problems Jan 15 20:35:20 So, how to tell what the problem actually is? Windows or DNS issue? Jan 15 20:35:38 can you plug it into your network router using a wire, directly? Jan 15 20:35:41 Besides reimaging to linux? lol Jan 15 20:35:45 and then SSH to it? Jan 15 20:35:54 If I had a 5v power supply, I could. Jan 15 20:35:55 using putty if needed Jan 15 20:36:24 hmm that would help ;) Jan 15 20:37:01 Alright... I'll go that route. Seems like it'd be less problematic (one hopes). Jan 15 20:37:16 probally the mDNS crap getting luck with a cached entry Jan 15 20:37:16 I wouldn't trust windows .. but it probably should work Jan 15 20:37:16 Thanks for the help so far. Jan 15 20:38:01 I've never plugged my beagle into windows :/ Jan 15 20:38:27 Wish I had a better grasp of linux. :( Jan 15 20:38:39 Linux is easy Jan 15 20:38:42 its a fair learning curve .. but its fun Jan 15 20:38:43 it is windows that is convoluted Jan 15 20:38:56 ds2 : depends how you've been brought up in computing :p Jan 15 20:39:10 It's a matter of familiarity is all. Jan 15 20:39:32 ds2 : if its all icons and menus .. linux has a bit more to it than that :) Jan 15 20:39:54 veremit: but windows has special cases to do everything. Linux (on the command line) is more ortogonal Jan 15 20:40:03 although ubuntu does have a lot to answer for in tht regard lately Jan 15 20:40:18 ds2: point and click ;P Jan 15 20:40:19 you learn the basics and everything falls into place with Linux. On windows, you need to learn something for everything Jan 15 20:40:31 point click, shift, control, windows, arrrrrggggg Jan 15 20:41:08 if you learnt computing by the command-line .. TOTALLY different story Jan 15 20:41:29 windows doesn't (Really) have a command-line .. its a bodge :p Jan 15 20:41:36 ah but it does Jan 15 20:41:49 anyways...lunch Jan 15 20:42:36 no no it realyl doesn't lol .. I can't imagine win8 having anything useful ... 7 is bad enough .. xp is just tolerable Jan 15 20:43:23 My objective is to learn how to automate various tasks via electronics. Sounds like my lack of linux know-how will continue to be a barrier til I get a handle on it. Jan 15 20:44:36 What flavor of linux is recommended these days? Sounds like Ubuntu has fallen out of favor? Jan 15 20:44:47 Trian3 .. take a look at arduino .. its a fairly easy way into programming and control Jan 15 20:45:08 all distro's have their individual merits Jan 15 20:45:39 I think hardcore's gravitate towards gentoo or something involving compilation .. Jan 15 20:45:47 Thought they were all the same (Arduino, BBB, Raspberry Pi, etc), just different hardware specs & support... no? Jan 15 20:46:00 otherwise the package-based distros are an easier intro. and less prone to breakage Jan 15 20:46:22 yes and no .. beagle/pi are actual computers .. the arduino is just a controller chip Jan 15 20:46:33 subtly different Jan 15 20:46:33 I see Jan 15 20:47:13 the lines are a bit more blurry these days with enhanced controllers with ARM cores .. like the beagle/pi but without the operating system essentially Jan 15 20:47:54 that's basically the difference .. it either runs linux or embedded 'something ' (eg. android) or it just runs bare assembler code Jan 15 20:48:26 Well, I've gotta run. Thanks again for the help. I'll see if I can get further with it after connecting via ethernet. If not, I'll be back. :) Jan 15 20:48:54 np good luck **** BEGIN LOGGING AT Thu Jan 15 22:43:38 2015 **** BEGIN LOGGING AT Thu Jan 15 22:48:32 2015 **** BEGIN LOGGING AT Thu Jan 15 23:02:32 2015 Jan 15 23:49:54 I am trying to work with rs-232 serial cape, its default is ttyo0, I connected the cape but cannot see its name in dmesf Jan 15 23:49:58 dmesg Jan 15 23:51:50 do i need to disable getty to make that work, or all i need to do is connect my serial device to it, but that did not help when I tried it earlier Jan 16 00:32:39 Hey, I'm confused by the PWM information for the beaglebone. I've read there are 8 PWM outputs, but a lot of images show more than 8 pins labeled "PWM" Jan 16 00:36:39 There is a lot of muxing going on--those may be places where PWM can be muxed to. Jan 16 00:36:51 Or, they may be software-driven, rather than hardware. Jan 16 01:24:46 Hey guys, in BoneScript, why does it only seem to update the PWM sometimes? Jan 16 01:26:54 Like I change the values in my script and it only changes the output 25% of the time. **** ENDING LOGGING AT Fri Jan 16 02:59:58 2015
