**** BEGIN LOGGING AT Sat Mar 18 03:00:02 2017
Mar 18 11:06:07 <jic23> Bbblue arrived and powers up on the 9v adapter i had lying around. Nice, but need to make wire for uart0 as tiny connector! Ah well, have the parts but might not get time this weekend...
Mar 18 11:08:25 <jic23> Ow those green LEDs are bright!
Mar 18 11:17:49 <jic23> Hohum, bag of flying leads i got have red on 0v line on all the connectors and black on 3.3v. nothing could possibly go wrong!
Mar 18 11:19:07 <jic23> Anyone have one of the cheap knock off crimp tools that are around for those jsh connectors?
Mar 18 11:20:11 <jic23> If all goes to plan i am going to move all my test sensors over to the blue from the ancient pxa boards they are currently bodge to... Going to need lots of cables!
Mar 18 11:21:28 <jic23> Nice board though Jkidner!
Mar 18 11:54:42 <jic23> Oops got reversed pinout. Right to left wrt silkscreen. Would be easier if my meter hadn't disappeared.
Mar 18 11:55:20 <jic23> Uart bodge cable made by shoving some headers in alongside the wires :)
Mar 18 11:55:54 <francesco_guardi> Hi i'm working on a proposal for GSoC
Mar 18 11:56:22 <francesco_guardi> Someone think it would be useful a remote deployer for BeagleBone?
Mar 18 11:57:23 <jic23> Maybe... What is your usecase?
Mar 18 11:58:27 <francesco_guardi> Watch this https://github.com/jadonk/bonescript/issues/148
Mar 18 11:58:50 <francesco_guardi> I think to a similar idea with zero configuration on board
Mar 18 11:59:48 <jic23> Hmm. Not really something i am interested in. Let's see what others think as they surface during the day!
Mar 18 14:37:54 <uka_in_> ravikp7: hi, there?
Mar 18 14:38:12 <ravikp7> Hi!
Mar 18 14:38:27 <uka_in_> thanks for pointing out that error
Mar 18 14:39:07 <ravikp7> uka_in: Did it work after  correcting it?
Mar 18 14:39:17 <uka_in_> but i since device.interface() takes default value as 0 shouldn't it work?
Mar 18 14:39:35 <uka_in_> i couldn't test now, will test tommorow
Mar 18 14:40:07 <uka_in_> also, what's so special with interface 1 why can't we use interface 0??
Mar 18 14:41:05 <ravikp7> uka_in: ok, I don't know about this, BBBlfs uses interface 1, try with both
Mar 18 14:41:32 <uka_in_> ok i will try
Mar 18 16:31:20 <thetransformerr> hey nerdboy: , please reply if available
Mar 18 16:32:32 <thetransformerr> nerdboy: I have been trying to contact you since a long time but couldn't catch you up on free node,is there any other mode where you are available
Mar 18 16:34:28 <thetransformerr> nerdboy:anyways I interested in implementing sonic anemometer, and found that it is developed for three axis commercially successfully but is yet to be implemented as open source
Mar 18 16:35:28 <thetransformerr> I have read CSAT3 manual and few other projects done by other hobbyists on either arduino or PIC
Mar 18 16:36:12 <thetransformerr> but all hobbyists have still developed only for 2-axis, so I wanted to ask you
Mar 18 16:37:04 <thetransformerr> nerdboy:what would classify as real target that can be achieved during summer
Mar 18 16:39:00 <thetransformerr> nerdboy:I am waiting eagerly for your reply and tried to contact 2 days ago but was unsuccessful, and as proposal date is just 2 days away, it would be great if I had got some guidance from you
Mar 18 16:39:32 <thetransformerr> nerdboy:I am on GitHub with same id as this nickname thetransformerr
Mar 18 16:41:27 <m_w> jic23: where do you think the best place for motor drivers is in the kernel tree?
Mar 18 16:44:24 <m_w> jic23: people keep suggesting IIO but I am not sure
Mar 18 17:03:50 <jic23> Not sure, would say yes for very smart ones like the stspin parts... Less so for dumber varieties.
Mar 18 17:05:31 <m_w> jic23: would a separate subsystem be in order?
Mar 18 17:05:49 <m_w> the beagle guys are looking for a place for a servo driver
Mar 18 17:05:58 <m_w> possibly consuming pwm
Mar 18 17:06:00 <jic23> Might be. Needs requirements laying out...
Mar 18 17:06:38 <m_w> seems motors have been left up to userspace hacks up till now
Mar 18 17:06:46 <jic23> If in IIO would expect direct control. I.e. go at this speed or go to this position.
Mar 18 17:07:08 <jic23> Yeah, but often need non trivial control loops.
Mar 18 17:07:20 <jic23> So arguably should be.
Mar 18 17:07:41 <m_w> hmmmm
Mar 18 17:08:24 <jic23> Swapping to laptop
Mar 18 17:09:08 <jic23> And getting a beer...
Mar 18 17:09:28 <m_w> jic23: this is a 2 beer topic :)
Mar 18 17:10:39 <jic23_> before or during?
Mar 18 17:10:39 <jic23_>  :)
Mar 18 17:11:15 <jic23_> justed wasted  a dumb our trying to fire up the mpu9250 on the blue due to a stray dtb that I put together earlier being picked up first by uboot. hmph.
Mar 18 17:11:40 <m_w> yikes
Mar 18 17:12:06 <jic23_> Me being inconsistent with where I was putting it.
Mar 18 17:12:09 <jic23_> working now.
Mar 18 17:12:37 <jic23_> Glad I ordered a box of jsh leads ;)
Mar 18 17:13:03 <m_w> what is you impression of the blue so far?
Mar 18 17:13:09 <jic23_> tiny plugs ;)
Mar 18 17:13:18 <jic23_> Pretty nice.
Mar 18 17:13:38 <jic23_> Really want to do a stripped down kernel though.  RCNs is great (running 4.10.1-bone)
Mar 18 17:13:48 <jic23_> but massive overkill if you are focusing on just one thing not mainline.
Mar 18 17:13:53 <nerdboy> thetransformerr: start with xy axis and add z if there's time
Mar 18 17:14:03 <m_w> I think it is pretty good general purpose machine
Mar 18 17:14:26 <jic23_> I miss proper ethernet... If nothing else my laptop is having issues with the usb fake version.
Mar 18 17:14:35 <jic23_> Not sure why and can't be bothered to debug at mo.
Mar 18 17:14:45 <nerdboy> vertical wind motions are much smaller especially near the surface
Mar 18 17:14:55 <jic23_> So shuffling sd cards which is a waste of time.
Mar 18 17:15:07 <m_w> indeed
Mar 18 17:15:10 <jic23_> Would have liked a stepper controller if I'm being fussy.
Mar 18 17:15:13 <nerdboy> 2-axis is vet useful for large set of use cases
Mar 18 17:15:21 <nerdboy> 3rd axis not so much
Mar 18 17:15:22 <jic23_> but then chances of blowing those up is rather high.
Mar 18 17:15:43 <jic23_> Hmm. A beer called Goliath that is actually drinkable.
Mar 18 17:16:13 <m_w> steppers controller would have been nice
Mar 18 17:16:19 <jic23_> On the motor front I bought some st-spin parts to mess with a while back, but blew up the dev board regulator.
Mar 18 17:16:23 <jic23_> blue v2 ;)
Mar 18 17:16:31 <nerdboy> *very useful even...
Mar 18 17:16:34 <jic23_> When the connectors get even smaller!
Mar 18 17:16:36 <m_w> I think this board is more targeted toward mobile robots
Mar 18 17:17:00 <jic23_> Yeah, true enough.  I'm cynical though and would use steppers on those too as nice to work with ;)
Mar 18 17:17:14 <jic23_> But something had to give and I think it's a good balance on the hole.
Mar 18 17:17:22 <jic23_> I'm loving the connectors though.
Mar 18 17:17:32 <m_w> I have helped with a mobile robot driven with steppers
Mar 18 17:17:45 <thetransformerr> nerdboy:yeah I was also thinking for xy axis
Mar 18 17:17:50 <jic23_> Plan is to do what I always meant to do with the black and never did.  Which is to start using it as my main sensor test board.
Mar 18 17:17:50 <m_w> "loving" them?
Mar 18 17:18:02 <jic23_> lots of them and sensible ish things brought out.
Mar 18 17:18:15 <jic23_> A gpio on the i2c would have been perfect I suppose but never mind.
Mar 18 17:18:42 <m_w> you can never have too much GPIO
Mar 18 17:18:47 <jic23_> Needs a pin out diag though.  Wasted a while earlier figuring out where pin 1 was on the uart ;)
Mar 18 17:19:09 <jic23_> Maybe a job for a budding gsoc student with some artistic skills? *looks hopeful*
Mar 18 17:19:28 <m_w> yeah if the connectors weren't so close the silkscreen could have been used
Mar 18 17:19:32 <thetransformerr> nerdboy:and in previous year GSoC I didn't find any mention of apparatus with sonic transducers, so do I have to create an apparatus also
Mar 18 17:19:42 <jic23_> it has been in places, you can see the dots, but most are covered up I think.
Mar 18 17:19:56 <jic23_> oh. It is there. I'm just blind ;)
Mar 18 17:20:05 <m_w> :D
Mar 18 17:20:09 <jic23_> just poking out from below the next plug.
Mar 18 17:20:39 <jic23_> Easy to plug uart for debug would suit me, but how many people are going to be diagnosing kernel boot failures on it ;)
Mar 18 17:20:58 <m_w> at first, plenty
Mar 18 17:21:11 <jic23_> Given RCN 4.10 kernel seems spot on, I'd love them to try standardising on moving with mainline, but possibly a step too far.
Mar 18 17:21:25 <nerdboy> thetransformerr: we had the murata s and r widgets
Mar 18 17:21:45 <jic23_> hmm. Wonder if I can find the guide for setting up the i2c mux for the magnetometer.
Mar 18 17:21:58 <nerdboy> i think he built a little test rig but not documented i guess
Mar 18 17:22:00 <jic23_> not in the s***ing docs.
Mar 18 17:22:17 <jic23_> (my docs that is so can't really complain ;)
Mar 18 17:22:24 <thetransformerr> nerdboy:would you please tell what are these widgets
Mar 18 17:22:50 <nerdboy> one is send one is receive
Mar 18 17:23:06 <thetransformerr> nerdboy:okk
Mar 18 17:23:13 <nerdboy> i think we really want the "outdoor" version this time
Mar 18 17:23:52 <nerdboy> http://www.murata.com/en-us/products/sensor/ultrasonic/proof
Mar 18 17:24:08 <thetransformerr> nerdboy:Yeah I am pretty sure We would achieve that :)
Mar 18 17:24:15 <m_w> jic23_: the docs aren't great for that imu
Mar 18 17:24:41 <m_w> jic23_: I think that there is a special document for the register interface
Mar 18 17:24:48 <thetransformerr> nerdboy: Any tips on proposal for GSoC and
Mar 18 17:24:49 <nerdboy> great compared to what exectly?
Mar 18 17:25:15 <nerdboy> do some math?
Mar 18 17:25:17 <jic23_> yeah, I vaguely recall them being a mess and licensing around the dmp being unclear to put it lightly.
Mar 18 17:25:35 <m_w> jic23_: okay I am going for a short walk with the family be back in 20ish minutes
Mar 18 17:26:04 <thetransformerr> nerdboy: math like literally equations or something else
Mar 18 17:26:22 <nerdboy> proposal should follow the guidelines, be careful with scope, leave time for testing, and do some reqs analysis
Mar 18 17:27:04 <jic23_> cool. That's a pretty short walk!
Mar 18 17:27:09 <nerdboy> i mean if should not assume something if you can analyze it and show it's feasible
Mar 18 17:27:36 <nerdboy> s/if/it/
Mar 18 17:28:43 <nerdboy> use the sensor specs and do some estimates of data throughput/timing/etc
Mar 18 17:29:23 <nerdboy> people tend to leave out the reqs analysis and jump right in...
Mar 18 17:31:21 <thetransformerr> nerdboy: I did some basic research on sonic anemometer and found it is an active research topic, so it would be good if we decide our scope right before starting project
Mar 18 17:31:51 <nerdboy> scope is part of the proposal/project plan
Mar 18 17:32:03 <jic23_> m_w: hohum, Documentation/devicetree/bindings/i2c/i2c-gate  not sure why I didn't think to look there ;)
Mar 18 17:32:12 <nerdboy> it will "adjust" but you need to start somewhere...
Mar 18 17:32:29 <jic23_> I 'probably' reviewed this - but it's lost somewhere on the otherside of a large number of beers ;)
Mar 18 17:32:31 <thetransformerr> may I show you a document tomorrow about the features that we can develop during summer, and thanks very much for your time
Mar 18 17:32:48 <nerdboy> ah, they put it in the Documentation folder...
Mar 18 17:32:57 <nerdboy> who would think to look there?
Mar 18 17:33:33 <thetransformerr> :)
Mar 18 17:33:38 <nerdboy> stick it i your github wiki maybe?
Mar 18 17:33:44 <nerdboy> *in
Mar 18 17:33:55 <thetransformerr> okk
Mar 18 17:42:18 <thetransformerr> nerdboy: I already got an arduino but beagle are hard to get by here in india, so should I order them now or it is sent once selected for GSoC
Mar 18 17:44:49 <nerdboy> that stuff should be on the bb wiki
Mar 18 17:45:01 <nerdboy> but yes, you get hardware if selected
Mar 18 17:47:45 <jic23_> m_w back in  a bit.  Supplies crisis.  Know idli mix in the house..
Mar 18 17:47:53 <jic23_> no idli mix that is.
Mar 18 17:58:34 <nerdboy> still can't parse that...
Mar 18 17:59:27 <ds2> idli?
Mar 18 17:59:57 <ds2> a cake mix apparently
Mar 18 18:05:55 <jic23_> no. Not cake!  Kind of closer to a dumpling.
Mar 18 18:06:02 <jic23_> you steam them.
Mar 18 18:06:27 <jic23_> and have them with samba (lentil based soup like thing)
Mar 18 18:07:03 <jic23_> well worth having if you happen to visit the right type of indian restaurant.  Definitely comfort food and the kid is ill.
Mar 18 18:12:55 <jic23_> downright weird bug of the day. Moved a dtb from one directory to another on an sd stick and it shrunk to become 0 bytes.
Mar 18 18:13:03 <jic23_> Get some really odd results if you try and boot off that!
Mar 18 18:15:01 <jic23_> and yeah. magnetometer working.
Mar 18 18:15:52 <ds2> sd bad probally. seen stuff like that on bad SD or corrupt FS
Mar 18 18:15:58 <ds2> try fsck.msdos on it
Mar 18 18:16:28 <ds2> the appropriate one if you are using the new fangled single FS setup
Mar 18 18:16:50 <jic23_> meh. Deleted and recreated ;)
Mar 18 18:17:07 <jic23_> all fine now. But more than like as this one came out of the scrap box.
Mar 18 18:25:30 <m_w> back
Mar 18 18:26:14 <jic23_> m_w good walk?  Magn and pressure now working.  All looking good.
Mar 18 18:26:36 <jic23_> hmm. ADCs not enabled by default though which is a little tedious.
Mar 18 18:26:59 <m_w> yeah that can be fun to enable
Mar 18 18:27:13 <m_w> they using dt overlays for the blue?
Mar 18 18:27:22 <m_w> the walk was okay
Mar 18 18:27:27 <m_w> little cold out
Mar 18 18:28:07 <jic23_> There is a straight DT file. Overlays to my mind don't make much sense for the bits that are soldered won.
Mar 18 18:28:15 <jic23_> Fair enough for the stuff on plugs.
Mar 18 18:28:42 <m_w> lemme take a look at the schematic
Mar 18 18:30:21 <jic23_> probably same as black. I just can't right now find my notes on that.
Mar 18 18:30:29 <m_w> yeah the adc SHOULD be enabled by default
Mar 18 18:30:40 <m_w> the header is clearly marked as ADC
Mar 18 18:31:53 <jic23_> yup.
Mar 18 18:32:47 <jic23_> found the original blog post I got it from before.
Mar 18 18:33:42 <m_w> why can't they just have a tree with the latest patches applied?
Mar 18 18:34:12 <jic23_> Would be nice.  Might put one together if no one else does....
Mar 18 18:34:37 <jic23_> *looks hopefully for other volunteers*
Mar 18 18:35:00 <m_w> what kernel are you using?
Mar 18 18:35:20 <jic23_> RCNs 4.10.1-bone1
Mar 18 18:35:32 <jic23_> built from his git branch.
Mar 18 18:35:39 <jic23_> using the 'magic' scripts...
Mar 18 18:35:51 <jic23_> Should distil those down to an old fashioned list of steps.
Mar 18 18:36:14 <jic23_> Only bit that didn't drop directly on the debian console image was to rename the zImage to vmlinuz..
Mar 18 18:36:49 <jic23_> It's hiding what is going on.  Just fine for a jenkins automated build, but nice expose people who are interested to the intermediate bits.
Mar 18 18:37:00 <m_w> https://github.com/beagleboard/linux/blob/4.4/arch/arm/boot/dts/am335x-boneblue.dts
Mar 18 18:37:09 <m_w> not seeing the adc here
Mar 18 18:38:26 <jic23_> I'll post a drop of the dts I edited if that works as well as the rest.
Mar 18 18:38:29 <jic23_> Sensors aren't in that either.
Mar 18 18:38:43 <jic23_> nope. Didn't work.
Mar 18 18:38:45 <jic23_> hohum.
Mar 18 18:38:50 <m_w> are they using the universal cape thing?
Mar 18 18:39:15 <jic23_> nah. Hacking directly on that dts.
Mar 18 18:39:22 <m_w> okay
Mar 18 18:40:32 <jic23_> hmm. it tried to add it and failed. hohum.
Mar 18 18:40:42 <m_w> &tscadc {
Mar 18 18:40:42 <m_w> 	status = "okay";
Mar 18 18:40:58 <m_w> adc {
Mar 18 18:41:00 <jic23_> or I can't count.
Mar 18 18:41:00 <jic23_> doh.
Mar 18 18:41:22 <m_w> ooops
Mar 18 18:41:33 <jic23_> time for the wet finger test.
Mar 18 18:41:49 <m_w> are they consuming some of the channels with other drivers?
Mar 18 18:42:36 <jic23_> nope.
Mar 18 18:42:40 <jic23_> not currently.
Mar 18 18:42:46 <jic23_> Should be for the battery, but they aren't.
Mar 18 18:42:56 <jic23_> not in rcn's kernel anyway.
Mar 18 18:43:19 <m_w> not seeing a registration for the battery voltage measurement
Mar 18 18:44:10 <m_w> not sure I see the point of the voltage divider driving AIN7
Mar 18 18:45:12 <jic23_> all the exposed pins are working.
Mar 18 18:45:24 <jic23_> I'd guess it gives a way of doing a board test.
Mar 18 18:45:50 <jic23_> Anyhow, guess I'll throw the devicetree changes somewhere. hohum.. Minimal blog post coming up.
Mar 18 18:46:21 <m_w> that would be good, where do you post your blog?
Mar 18 19:05:35 <jic23_> http://jic23.blogspot.co.uk/2017/03/notes-on-beagle-bone-blue.html
Mar 18 19:05:41 <jic23_> Don't exactly post often as you can see ;)
Mar 18 19:05:52 <jic23_> Last post nearly 10 years ago.
Mar 18 19:06:02 <jic23_> Well actually I have a few half written ones from last year.
Mar 18 19:06:46 <jic23_> Might flesh this out sometime. Anyhow, out of time and will have to do some review catch up if I get any tomorrow.  Have a nice afternoon.
Mar 18 19:06:50 <jic23_> bye
Mar 18 19:30:48 <widdzz> Hello, I would like to participate in the GoSC by contributing to BeagleBoard, but I have no experience working with beagleboard, I only have introductory experience with Arduino/Galileo/Waspmote. Is this something I can learn while on the job with guidance from my mentor? or Do I need to be proficient at it already?
Mar 18 20:13:32 <nerdboy> that depends, if you can get your hands on a beaglebone now you might have time to spin up on a less esoteric project idea...
Mar 18 20:14:29 <nerdboy> pru's are a little bit like a microcontroller
Mar 18 20:15:15 <nerdboy> mainly C or assm but the syntax is TI-specific using cgt
Mar 18 20:15:39 <nerdboy> gcc also supports pru elf but not so mature yet
Mar 18 21:54:35 <widdzz> @neaboy thank you. Unfortunately I cant get a BeagleBone now
Mar 18 21:59:45 <widdzz> sorry I meant to type nerdboy
Mar 18 22:01:47 <widdzz> What is the learning curve like? Do you know of any material such as examples or tutorials I can look at?
Mar 18 23:18:04 <nerdboy> in the pru project notes, etc...
Mar 18 23:18:18 <nerdboy> on the ideas page
Mar 19 02:27:11 <k_thax> hello
