**** BEGIN LOGGING AT Fri Nov 11 03:00:01 2016 Nov 11 06:12:03 Hey it's pretty late, anyone still awake? Nov 11 06:22:09 it's pretty early here in eastern europe Nov 11 06:30:43 and even more early here in central/western europe Nov 11 07:23:07 Hi Nov 11 07:23:42 i am new to BBB Nov 11 07:24:00 i need some information about memory mapping in BBB Nov 11 07:24:20 is anyone can help me in this? Nov 11 07:25:46 hello Nov 11 07:27:59 kms: it probably helps if you actually ask a *question*, and be patient. people here are in all kinds of different timezones and may very well be doing other stuff most of the time and look only occasionally at irc Nov 11 07:33:37 http://www.catb.org/esr/faqs/smart-questions.html Nov 11 07:42:38 hi Nov 11 09:52:23 hello, anyone knows about some changes in beagleboneblack rev c? I was using script to copy emmc to sd, and clone it to another device. With newest bbb rev.c it doesnt work. After flashing the image from sd card, beaglebone dont want to boot. Tried on older boards with same image and works nicely. Any idea? Thanks Nov 11 10:14:01 Anyone knows a simple way to measure CPU cycles on beaglebone? Like RDTSC on x86? Nov 11 10:20:51 there's a cycle counter but unfortunately it's privileged by default Nov 11 10:22:49 Igor__ : what kernel version are you using ? Nov 11 10:22:58 overlord_tm: there might be a way to request access on linux but I'm not 100% sure Nov 11 10:23:25 zmatt, the thing in PMU? Nov 11 10:26:00 yeah, stupidly ARM didn't think it might be useful to allow unprivileged reading of the cycle counter, or at least have a separate enable bit for that. instead there's one bit that gives userspace basically full access to the pmu Nov 11 10:26:10 iirc Nov 11 13:07:41 Hi, I'm working with Beagleboard X15, and I want to connect some breakout board for the GPIOs to make the more accessible. anyone knows what connector/breakout should I buy? Nov 11 16:00:02 Can I come to free up space? Nov 11 16:00:52 Without using the SD Card Nov 11 16:04:20 Can I come to free up space? Nov 11 16:09:28 HI, just installed debian 8.6 image (4.4.23-ti-r51) how are GPIOs managed ??? (i always used the jurassic "echo 1 > /sys/class/gpio/..../value" method to control them :-((( ) Nov 11 16:13:45 in old 3.2 kernel..... Nov 11 16:52:22 fred_tv: yep, still the same Nov 11 16:54:25 (after manually exporting them, or declaring them in DT using gpio-of-helper to get them set up and exported automatically) Nov 11 16:55:43 I made some enhancements myself to allow the latter to be recognized by udev to set ownership/permissions on them and make symlinks by label in /dev/gpio/ Nov 11 16:56:05 I think rcn merged those in 4.8 or 4.9 Nov 11 17:01:17 there's also a new device mechanism in 4.8/4.9 but it's crap in my opinion Nov 11 17:14:30 Hey. I'm having some issues understanding the differences about the BBB and BBB industrial. Is it just the operating temperature and materials? Nov 11 17:27:53 zmatt: i'll continue with old simpler method.... Nov 11 17:28:15 thanks Nov 11 17:29:53 frmendes : Operating temperature range of BBB itself is very good, which is sufficient for most of the industrial purposes Nov 11 17:31:14 tejas_ : That's what was confusing me. The industrial BBB differs from the "normal" BBB because it's better suited for industrial uses, right? Nov 11 17:31:21 other than that, going with BBB is a safe bet Nov 11 17:35:19 frmendes : BBB is always a safe bet. Industrial doesn't imply that its well suited for industrial applications, it depends on what exactly you want to use the board for in which environment Nov 11 17:35:37 home automation, definitely Nov 11 17:37:34 Home automation is not an industrial use. BBB is to go for. Nov 11 17:38:15 how exactly you are planning to use it ? Nov 11 17:38:27 As a hub or central controller etc Nov 11 17:45:21 zmatt: are you a linux kernel expert? Nov 11 18:11:50 tejas : something like a central controller Nov 11 18:12:18 it's mostly a side project. collect environmental data and sending it to a server for starters **** ENDING LOGGING AT Sat Nov 12 03:00:00 2016
