Sep 30 09:42:26 tbr-foo problem after new flash where the hostkey may not generated Sep 30 09:42:46 ah, yes Sep 30 09:42:54 when i type ssh root@192.168.7.2 it just does nothing Sep 30 09:43:01 aum connect a ftdi or like serial console cable and login over that Sep 30 09:43:37 thank you but i haven't got one of those Sep 30 09:44:12 i can get into it using an app called Coolterm similar to Putty Sep 30 09:44:37 only not sure what to do there as MC don't work properly in that app Sep 30 09:46:20 aum why did you buy a board without owning a serial cable to connect? Sep 30 09:46:28 serial cable is a life saver Sep 30 09:46:52 I connect via usb Sep 30 09:48:34 is it worth trying ethernet to connect or maybe just re flashing the bbb Sep 30 10:00:37 hi Sep 30 10:01:02 does beaglbone support USB 3.0 ? Sep 30 10:01:08 no. Sep 30 10:01:25 then, USB 2.0 !! Sep 30 10:01:53 usb 0.5 Sep 30 10:01:58 its only half-working :) Sep 30 10:02:05 ok Sep 30 10:02:07 thankis Sep 30 10:02:12 thanks Sep 30 10:22:42 lol Sep 30 11:31:02 hello all, .. I need some help with the SPI interface w\out interrupts ..can u^ help me? Sep 30 11:33:12 depends Sep 30 11:37:18 when using the SPI code sequence (enable CS, ..transmit/receive, disable) from gpio ISR i get some noise back in the trigger pin witch is input only Sep 30 11:52:40 i've minimized the SPI read code to simple registry commands (sequence works at 512 ksps in main loop) ..but when using a triggered input, the gpio ISR fails to keep a constant speed and the trigger channel(input) becomes noisy and SPI CS length fluctuates for the same number of bits Sep 30 11:53:24 using 1 word of 32 bits Sep 30 12:01:05 is there a problem if spi is controlled by gpio input triggered isr? Sep 30 12:02:00 you do gpio-spi? Sep 30 12:02:21 that will of course fluctuate, as it's done in software, bit-banging rpi style Sep 30 12:02:33 no ..the spi code is inside gpio isr Sep 30 12:02:53 what do you mean by gpio isr? Sep 30 12:03:23 interrupt routine to start spi read Sep 30 12:03:38 triggered from external input Sep 30 12:05:40 the spi code have 2 while loops for transmit and receive registers .. Sep 30 12:06:36 but why is the input_only (trigger pin) becoming noisy .. Sep 30 12:06:41 ? Sep 30 12:08:25 * KotH does not understand the setup Sep 30 12:12:06 i'm using spi to read 32 bits from ADC ..only when a gpio pin (trigger) becomes high Sep 30 12:12:55 yes, but where does your code run? in kernel space? user space? how do you access spi? what driver do you use? why is my chocolate bar shrinking? Sep 30 12:13:45 i'm working with starterware in bare metal Sep 30 12:13:48 koth because you are eating it Sep 30 12:14:06 I never heard of starterware Sep 30 12:14:16 where did you get it from? Sep 30 12:14:31 woglinde: Ti tool to write code on bare metal Sep 30 12:14:36 from TI's website Sep 30 12:14:50 jmikii: very few people use starterware Sep 30 12:15:09 jmikii: we get questions like yours once every 2-3 months Sep 30 12:15:26 jmikii: nobody can answer them because this channel is mostly linux based Sep 30 12:15:35 jmikii: ask your friendly Ti representative Sep 30 12:16:34 ok, thanks KotH, i'll stick around maybe i'll change to linux in the future .. Sep 30 12:17:19 jmikii: hmm.. that sounds like the decision for starterware was not a concious decision? Sep 30 12:19:19 KotH: i'm looking for "as fast as possible" spi read .. Sep 30 12:19:41 as fast as possible <> spi Sep 30 12:20:01 jmikii: which fast? Sep 30 12:20:08 jmikii: latency or troughput? Sep 30 12:20:25 troughtency Sep 30 12:20:41 KotH: 1 MSPS 32 bits Sep 30 12:21:15 32Mbit/s Sep 30 12:21:31 hmm... Sep 30 12:21:40 does teh am335x suppor that spi clock? Sep 30 12:22:04 it supports 48mhz clock Sep 30 12:22:14 other than that, linux can easily sustain 4Mbyte/s Sep 30 12:22:28 that doesnt translate to 48 mbit/byte/whatever/s though Sep 30 12:23:59 gurki: a 48MHz clock translates into >40Mbit transfer rate Sep 30 12:24:05 roughly Sep 30 12:24:14 theoretically. practically i found it hard to archieve any of theese rates Sep 30 12:24:29 would be happy to be told wrong ... Sep 30 12:24:31 :) Sep 30 12:24:50 * KotH has acheived 24MHz -> 22Mbit/s on an arm7 Sep 30 12:24:58 with 8bit data Sep 30 12:25:00 nice Sep 30 12:25:08 didnt even get close to that :O Sep 30 12:25:33 you shouldnt use node.js for that kind of stuff ;) Sep 30 12:25:45 * tbr giggles Sep 30 12:25:54 well done ..KotH, where you using bare metal? Sep 30 12:26:04 jmikii: yes Sep 30 12:26:14 im not exactly using node.js :P Sep 30 12:26:28 but i guess i should choose my libs more wisely Sep 30 12:26:30 also using interrupts in spi? Sep 30 12:26:37 jmikii: ofc Sep 30 12:26:48 jmikii: shuffling everything trough to usb Sep 30 12:26:51 could you link me yours? or did u write it from scratch? Sep 30 12:27:08 gurki: sorry, nope. company owned code Sep 30 12:27:35 nm. dont ve to if ure not allowed to ... ;) Sep 30 12:27:55 i dont even have access to the code Sep 30 12:27:57 ;) Sep 30 12:28:03 *g* Sep 30 12:28:33 KotH, what is ofc? Sep 30 12:29:30 of course Sep 30 12:29:56 ofc :)) Sep 30 12:30:19 sorry.. got too used to abreviate stuff ^^' Sep 30 12:30:32 sry! Sep 30 12:30:44 thanks all .. Sep 30 13:26:25 So, yesterday, I was asking about possible USB issues freezing up my BBB. It looks like I got a freeze last night so I'll post some logs up shortly if it looks like they contain anything useful. Sep 30 13:28:23 Also, I'm a total n00b at IRC. How do you guys keep track of conversation that goes on while you're disconnected from the channel/Internet? Sep 30 13:29:58 you dont disconnect Sep 30 13:30:25 touche. Sep 30 13:30:40 unfortunately, i'm bound to a laptop at the moment. Sep 30 13:30:56 you can search the logs ... Sep 30 13:31:09 most of us run irssi in a screen session Sep 30 13:31:14 or use bnc and the like Sep 30 13:32:17 got it. thanks Sep 30 13:32:31 http://beagleboard.org/static/irclog/ Sep 30 13:35:24 ah, that's perfect. didn't know they kept logs online. Sep 30 13:57:43 HI, does someone know how to do a clean shutdown of BBB on power loss? I use debian with kernel 3.8. I've found something for raspi, but it's some kind of overkill: http://juice4halt.com/ Sep 30 13:59:23 <_av500_> you can do the same Sep 30 13:59:26 this sounds kind of mutually exclusive ... Sep 30 13:59:36 I was looking into the same thing awhile ago...I ended up just keeping the root filesystem mounted as readonly to prevent disk corruption. Sep 30 13:59:38 "clean shutdown" and "power loss" Sep 30 13:59:58 yeah, i think readonly rootfs is the only sane thing here Sep 30 14:00:19 <_av500_> well, ads a tiny UPS Sep 30 14:00:21 <_av500_> add Sep 30 14:00:23 unless you have a battery attached that can prevent fs corruption by doing a clean unmount Sep 30 14:00:30 *snap* Sep 30 14:00:31 :) Sep 30 14:01:17 yes, the plan is to trigger an shutdown command when the main power is lost (detected through some gpio-pin) in the meantime during shutdown power the BBB from some supercap Sep 30 14:02:02 <_av500_> sure Sep 30 14:02:03 the root file system can be mounted ro, but what about the opened files from user apps? Sep 30 14:02:03 <_av500_> doable Sep 30 14:02:12 <_av500_> what user? Sep 30 14:02:16 <_av500_> scholkid? Sep 30 14:02:19 <_av500_> school Sep 30 14:02:27 root Sep 30 14:02:28 <_av500_> do you really have that use case? Sep 30 14:02:30 *g* Sep 30 14:02:31 you call sync for open files ... Sep 30 14:02:48 well, at least to flush the cache Sep 30 14:02:55 <_av500_> BennyB_: it is all doable, but why Sep 30 14:04:02 for my application, i have a microsd mounted as rw, and all my data is sqlite, with a write ahead log enabled. i haven't had any issues when repeatedly yanking the power. Sep 30 14:04:18 yeah, my app continously writes "logfiles" and reads data from "programs" so if power gets lost I need to write the last step to logfile and do safe state of my outputs Sep 30 14:04:54 <_av500_> ok Sep 30 14:04:59 <_av500_> a real world use case Sep 30 14:05:12 <_av500_> so add a few supercaps and detect the power los Sep 30 14:05:18 <_av500_> loss Sep 30 14:05:40 and then just do a proper shutdown call Sep 30 14:05:48 yes, that's the plan. a script then tells the app to shut down Sep 30 14:05:58 <_av500_> just dont use bash Sep 30 14:06:06 why? Sep 30 14:06:11 <_av500_> its unsafe Sep 30 14:06:21 *repeat* why? Sep 30 14:06:51 us dash :) Sep 30 14:06:54 *use Sep 30 14:08:32 trollific Sep 30 14:08:45 ogra_: how's RTMing going? Sep 30 14:09:06 I will do some more research on this issue.. thought someone here has ever had this issue and got url to look on. Sep 30 14:09:13 tbr, exhausting !!! Sep 30 14:09:37 * ogra_ looks forward to not have 16h workdays anymore at some point :) Sep 30 14:09:46 ogra_: happy end in sight? Sep 30 14:09:53 but it stabilized massively over the last month Sep 30 14:10:00 yeah Sep 30 14:10:11 nice to hear Sep 30 14:10:14 :) Sep 30 14:10:24 * tbr should update and try it Sep 30 14:10:29 ++ Sep 30 14:12:24 ogra_: also asking as I'm wondering when victor might get around to my stuff. Sep 30 14:12:47 i could poke him agaiin but i doubt it is a good time atm Sep 30 14:13:04 and tvoss is on vacation for at least this week still Sep 30 14:13:06 see, that's why I asked you if hell is stell breaking loose ;) Sep 30 14:16:07 <_av500_> BennyB_: you can be the one to make the URL Sep 30 14:16:11 <_av500_> 1r5 min of fame Sep 30 14:16:14 <_av500_> 14 Sep 30 14:16:15 <_av500_> 15 Sep 30 14:53:24 hey all. I am getting continuous logs on my beagle bone black running debian and configured as a wireless accesspoint using hostapd. I have no clue what the messages mean, but it does seem to have to do with the wireless module. Sep 30 14:53:28 The logs are on http://pastebin.com/6ET3YQjA Sep 30 14:53:45 does anyone have a clue what these messages mean? Sep 30 14:56:22 SmokeyD which driver? Sep 30 14:56:37 and you have proably to look into this driver to get the meanings Sep 30 14:57:47 woglinde: rtl8192cu Sep 30 15:03:43 log spam is spam Sep 30 15:04:06 SmokeyD: probably nothing Sep 30 15:04:51 av500 yes debug left overs Sep 30 15:05:03 I looked it up Sep 30 15:38:12 The reference manual for the BeagleBone Black says that I can disable the 24.576 MHz audio clock on gpio3_21, but I can't find any documentation on how to do that. Is this documented somewhere? Sep 30 15:38:53 on the bbb, can angstrom be used to operate the spi as a master? Sep 30 17:17:10 Hello? Sep 30 17:20:47 yes? Sep 30 17:51:39 on the bbb, can debian be used to operate the spi as a master? Sep 30 17:56:33 yes Sep 30 17:56:58 jacekowski: do you have any examples? Sep 30 17:57:41 wups, sorry. Sep 30 17:57:44 i meant to ask: Sep 30 17:57:50 on the bbb, can debian be used to operate the spi as a slave? Sep 30 17:58:45 dunno Sep 30 17:58:47 probably yes Sep 30 17:58:57 but you might have to write your own drivers Sep 30 18:02:17 i meant without writing your own driver. if you write your own driver, then of course you can do just about anything the bare metal is capable of Sep 30 18:02:51 but perhaps i'm a wuss and should just dive into driver development, which i've never done under linux... Sep 30 21:25:42 anyone here use slackware? Sep 30 21:25:50 i'm about to put slackware arm on my bbb Sep 30 21:29:47 why not Sep 30 21:32:11 woglinde: i might be getting a job where the boss has used slackware in his company for since 1994 Sep 30 21:32:23 i need to freshen up Sep 30 21:32:53 kernel configuration will be the biggest challenge tho Sep 30 21:33:09 i dont want to put slackware on my laptop really it will feel like a downgrade :D Sep 30 21:33:29 ok lets get cracking on this Sep 30 21:33:39 /me plrays not to brick it Sep 30 21:33:43 prays Sep 30 21:37:27 I do not would work for a company where slackware is dominating Sep 30 21:40:08 i guess thats a good point lol Sep 30 21:40:46 question, the emmc flash Sep 30 21:41:00 do i need to make it as an image of some kind? Sep 30 21:41:07 ? Sep 30 21:41:13 or does it just take whatever is on the sdcard and copy it Sep 30 21:41:14 partion it Sep 30 21:41:23 partition the emmc? Sep 30 21:41:44 sure Sep 30 21:41:58 :O Sep 30 21:42:00 or boot from sdcard Sep 30 21:42:21 how do i get the emmc flash to work. i will boot from the sdcard in the beginning while i am configuring my kernels Sep 30 21:46:24 good nite Sep 30 21:47:59 night Oct 01 00:42:50 ello Oct 01 01:05:45 omg this sdcard is takeing forever to flash Oct 01 01:16:17 i tried putting slackware userspace and debian kernel together Oct 01 01:16:28 the debian kernel should be able to boot slackware right?
