Oct 02 03:15:03 <yates> i git clone'd the kernel and checked out v3.8.13 and found a whole bunch of files named spi-xyz under the drivers path. how do i know which ones went into the 3.8.13-bone64 build?
Oct 02 03:17:41 <yates> even looking at the spi stuff in th ebeagleboard linux tree here: https://github.com/beagleboard/linux/tree/3.8.13-bone64/drivers/spi
Oct 02 03:18:31 <yates> it appears there are files for other architectures, e.g., the AD blackfin (bfin-sport) and power pc (ppc4xx.
Oct 02 03:23:07 <yates> ds2: i'd really like to know why you think kernel module drivers are not good.
Oct 02 03:23:28 <yates> at least for an SPI driver.
Oct 02 04:38:05 <PGBeagle> I have had my Beaglebone Black for a few months now and am very happy with it.  Now I need some help to go further.  Have I come to a good place for information?  (BTW, I am new to IRC!)
Oct 02 04:40:45 <PGBeagle> Anybody Home?
Oct 02 04:49:03 <ds2> read the TRM and understand the chip!
Oct 02 05:47:03 <LetoThe2nd> PGBeagle: your chances of getting the information you want are actually considerably higher if you tell us what you'd like to know (instead of "is this a good place for information")
Oct 02 08:21:27 <Amila> hi
Oct 02 08:22:14 <Amila> I have programmed a little code with my beaglebone black
Oct 02 08:22:36 <Amila> and i just want to know how to setup it as the default programme to run
Oct 02 08:23:57 <Amila> any help would be appriciated
Oct 02 10:18:08 <flysky> hi
Oct 02 10:51:05 <_rotti> hi
Oct 02 10:59:09 <PGBeagle> I am new to IRC.  I don't have a spicific question at this point,  I just wanted to know if had this IRC viewer working correctly.  Thanks!  I will, no doubt, be asking more questions later.
Oct 02 10:59:23 <KotH> seems to be working
Oct 02 10:59:29 <KotH> but it's called "irc client" ;)
Oct 02 11:00:07 <PGBeagle> Thanks!
Oct 02 11:06:47 <PGBeagle> If I see someone reply with my Nickname after theirs, does that mean that they responded privately? Or is there another way to designate a response to a certain person?
Oct 02 11:07:13 <_rotti> PGBeagle: everyone can read this ;)
Oct 02 11:09:03 <PGBeagle> Yes, but you replied,  my name is listed after yours.  How do I reply to a specific persons question, rather than putting out a general broadcast?   (Maybe there is a channel for newbes)
Oct 02 11:10:28 <_rotti> PGBeagle: just type the name. depending on your client, tab completion would work... don't know about a newbie channel here, but i'm sure there is one... try to google some irc faq
Oct 02 11:12:13 <PGBeagle> _rotti:  Thanks!
Oct 02 11:15:31 <av500> PGBeagle: you reply to somebody specific, but still everybody sees it
Oct 02 11:15:38 <av500> also, first rule of IRC: google it
Oct 02 11:15:47 <av500> that includes how IRC works
Oct 02 11:15:59 <av500> you are not the first IRC "newbie"
Oct 02 11:17:34 <KotH> av500: are you sure? i havent seen an irc newbie in ages... i thought they were exctinct
Oct 02 12:11:08 <cityoflights2> well, I am back
Oct 02 12:11:41 <cityoflights2> I am having trouble with a water flow sensor
Oct 02 12:11:53 <cityoflights2> fs300a
Oct 02 12:12:03 <cityoflights2> is anyone using it?
Oct 02 12:24:22 <av500> cityoflights2: define trouble
Oct 02 12:24:25 <av500> is it callign you names?
Oct 02 12:24:33 <cityoflights2> hi av500
Oct 02 12:24:54 <cityoflights2> I setup the flow sensor at the garden pipe
Oct 02 12:25:24 <cityoflights2> the sensor is ment to messure 1-60 Litre per sec
Oct 02 12:25:42 <cityoflights2> yet I get far more pulses
Oct 02 12:26:16 <av500> use less water :)
Oct 02 12:26:18 <cityoflights2> I am using an interapt to call from the GPIO
Oct 02 12:26:44 <cityoflights2> and set the pin to edge = "both"
Oct 02 12:27:20 <cityoflights2> I have reason to beleave the sensor gives me noise, and need to filter it
Oct 02 12:27:53 <av500> well, have a look
Oct 02 12:27:59 <av500> attach a scope and see
Oct 02 12:28:28 <cityoflights2> I don't have one
Oct 02 12:28:44 <cityoflights2> was hoping someone else used it
Oct 02 12:29:04 <cityoflights2> most information on the web is not so helpfull
Oct 02 12:29:23 <LetoThe2nd> well doing sensor circuitry without a scope is bound to be painful
Oct 02 12:29:24 <cityoflights2> they use a sleep of 1000 ms after each trigger
Oct 02 12:29:34 <cityoflights2> I see
Oct 02 12:29:49 <av500> well
Oct 02 12:29:54 <LetoThe2nd> wellwell
Oct 02 12:30:01 <av500> you can do some debugging without
Oct 02 12:30:05 <av500> make sure your SW works
Oct 02 12:30:12 <av500> toggle a switch and count pulses
Oct 02 12:30:16 <av500> use a pulse generator
Oct 02 12:30:17 <av500> etc..
Oct 02 12:31:15 <cityoflights2> a scope will only prove the pulses are electricly OK
Oct 02 12:31:24 <LetoThe2nd> nope
Oct 02 12:31:29 <cityoflights2> yet it wont make much sense beyond this
Oct 02 12:31:35 <cityoflights2> please explain
Oct 02 12:31:52 <LetoThe2nd> with a scope you can also see if there are other things on the line that could get mis-interpreted as pulses
Oct 02 12:32:10 <cityoflights2> OK
Oct 02 12:32:16 <LetoThe2nd> and depending on your input circuitry, that can be a lot.
Oct 02 12:32:39 <cityoflights2> I will try to borrow one
Oct 02 12:33:04 <av500> as said, you can do other things too
Oct 02 12:33:12 <av500> connect something "known good"
Oct 02 12:33:21 <av500> make sure your SW is ok
Oct 02 12:33:22 <av500> etc..
Oct 02 12:33:55 <LetoThe2nd> a usual technique is to power such sensors from a higher, less noise-sensitive source at like 12V or 24V, then do some input filtering and deglitching in hardware at the same point as you are bringing it down to the 3.3V or whatever you need.
Oct 02 12:34:25 <cityoflights2> I see
Oct 02 12:35:48 <LetoThe2nd> a 3.3v sensor powered from the bbbs power out, connected over a few meters of unshielded wire, drawing an unknown number of milliamperes itself, and the even mechanically toggling some output that goes back over the same wire type for example is the exact opposite of "stable circuitry"#
Oct 02 12:36:00 <LetoThe2nd> that will work maybe on your desk, but not in real life
Oct 02 12:36:53 <LetoThe2nd> but of course, also follow what av500 said. its usually not one thing alone that makes data aquisition good, but the careful use of a number of different techniques
Oct 02 14:52:26 <_stu__> hey whats the size of the uart fifo buffers in the bbb?
Oct 02 14:52:37 <av500> why not check the TRM?
Oct 02 14:53:17 <_stu__> i've checked and i dont see it
Oct 02 14:53:26 <_stu__> looking in chapter 19...uart..of the trm
Oct 02 14:54:04 <_stu__> http://www.ti.com/lit/ug/spruh73k/spruh73k.pdf
Oct 02 14:56:13 <_stu__> sooo..any other suggestion?
Oct 02 16:10:34 <sheridp> Does anyone have experience using the MCSPI bus on the BBB by writing directly to the registers (eventually I'll be doing it from the PRU). I can get it to work from userspace using SPIdev, but not using mmap.
Oct 02 16:14:03 <sheridp> Specifically, I can write to TX0, but the device never starts transmitting
Oct 02 16:14:19 <av500> you missed some detail
Oct 02 16:14:21 <av500> pinmux?
Oct 02 16:14:23 <av500> clocks?
Oct 02 16:14:28 <av500> the usual suspects
Oct 02 16:16:31 <sheridp> maybe, but it seems to work with SPIdev ok.  One thing I find a little weird is that even after using SPIdev, the SPI0_CLKCTRL is still disabled
Oct 02 16:21:55 <sheridp> On thing that might be helpful is just checking the SPIdev source code, but I can only find spi-omap2-mcspi.c which I'm not sure is right for the AM335x processor
Oct 02 16:24:06 <av500> spidev is the kernel driver
Oct 02 16:24:22 <av500> ignore the omap2
Oct 02 16:24:25 <av500> its the one
Oct 02 16:24:30 <av500> the kernel driver works
Oct 02 16:24:38 <av500> but then the kernel does all the clk and pinmux
Oct 02 17:42:39 <nandxor> Hi, I've been googling for the last month, but would anyone have a good place to start for android userspace drivers? (GPIO I2C?)
Oct 02 18:52:50 <tux_> Hi all, I have a question about wireless on BBB. I have a Dlink DWA-121 nano wireless adaptater which works pretty well on latest default BBB debian image (with 8192cu wireless driver and external power supply).  I however sometimes experiment problems with connections to AP (wicd results in "Not connected status" even though I am close to AP), as well as systematic connections drops (usually less than 20 mins after being connected).
Oct 02 18:53:55 <tux_> Does anyone has an idea on how to solve this issue ? Should I definitively try another dongle ? Many thanks in advance.
Oct 02 19:29:06 <sheridp> Should the SPI0 begin transmitting immediately after writing to TX0 if the FIFO is disabled?
Oct 02 20:25:44 <pkj007> hiii, I am new to beaglebone and git and I want to download armstrong code, do some changes in it, buuild it and then flash it in my beagle bone to see the effect...can anyone help??
Oct 02 20:27:32 <pkj007> looks like all are sleeping :(
Oct 02 20:30:12 <pkj007> help help!!!
Oct 02 20:39:53 <tux_> @pkj007 http://derekmolloy.ie/building-angstrom-for-beaglebone-from-source/ ?
Oct 02 20:54:28 <pkj007> @tux_  in this tutorial where m i downloading the angstrom source code?
Oct 02 20:56:31 <pkj007> @tux  step 1 is downloading the script..step 2 is configuring and step 3 is building
Oct 02 20:57:02 <pkj007> where m i downloading the angstrom source code in my local system or personal git?
Oct 02 21:07:17 <tux_> @pkj007 once you have cloned the scripts, go in the scripts folder, then "git branch -a"
Oct 02 21:08:13 <tux_> @pjk007 as specified in http://elinux.org/Dummies_Guide_to_Building_Angstrom_Linux_for_MinnnowBoard for example.
Oct 03 01:24:04 <kewvoq> Hi everyone! I just got a beagle bone black and Im trying to upgrade the kernel on my device. however /boot/uboot seems to be full :/ has anyone encountered this issue before?
