**** BEGIN LOGGING AT Wed May 25 02:59:58 2016
May 25 12:30:36 <jkridner> nerdboy: Doh! this doesn't look like a breakout board.
May 25 12:30:50 <jkridner> nerdboy: previous order already placed.
May 25 13:08:02 <chanakya_vc> hey bradfa,mdo,are you there?
May 25 13:08:14 <chanakya_vc> *mdp^^
May 25 13:08:17 <bradfa> chanakya_vc: hi
May 25 13:09:22 <chanakya_vc> bradfa,received the BBB today :D
May 25 13:09:22 <chanakya_vc> Infact just now
May 25 13:12:20 <chanakya_vc> bradfa, In other news,I have written the PRU hello world.But I don't have led's at home to test it.So am going to modify it a bit.
May 25 13:13:27 <chanakya_vc> It compiled using the makefile given on the hands on lab site,but I did not understand the entire makefile :( .So i would have to work on that a little more.
May 25 13:13:53 <chanakya_vc> But I seem to have got the gist of it.
May 25 13:17:00 <bradfa> chanakya_vc: good to hear! :)
May 25 13:17:05 <bradfa> chanakya_vc: go steal some LEDs from your lab :)
May 25 13:17:26 <bradfa> chanakya_vc: once you get it working, please post your code to github, including the makefile you're using
May 25 13:18:03 <bradfa> chanakya_vc: once your exams are finished, you should be making commits to your git respository for your firmware/kernel code at least 4 days every week
May 25 13:19:48 <chanakya_vc> bradfa,Yes I will.Although the code is not really my original.I took it from the the TI website.
May 25 13:20:05 <bradfa> chanakya_vc: that's ok
May 25 13:21:20 <chanakya_vc> bradfa,Last exam left on friday.Unfortunately it is the toughest too. Electrical Machines.
May 25 13:22:33 <chanakya_vc> bradfa,So I will try my best to do so.But I promise that by next wednesday,I am going to get a basic code implementing SPI firmware on Github.
May 25 13:22:49 <chanakya_vc> Then I will add additional features.
May 25 13:22:59 <chanakya_vc> Infact before wednesday.
May 25 13:23:36 <bradfa> chanakya_vc: ok, sounds good
May 25 13:23:43 <bradfa> chanakya_vc: will you be able to attend today's meeting?
May 25 13:23:52 <chanakya_vc> Yep I will come
May 25 13:23:58 <chanakya_vc> bradfa ^^
May 25 13:24:25 <bradfa> chanakya_vc: and you obtained a TTL to serial port adapter?
May 25 13:25:41 <chanakya_vc> But again might not stay for more than an hour.It's there in my lab.I might have to solder the thing together though.Infact,my lab makes these TTL converters through our local design
May 25 13:25:47 <chanakya_vc> bradfa^^
May 25 13:25:56 <bradfa> chanakya_vc: ok
May 25 13:26:19 <chanakya_vc> bradfa, So I am totally set for the summers :D
May 25 13:26:28 <bradfa> chanakya_vc: ok good to hear :)
May 25 13:26:29 <chanakya_vc> Excitement!
May 25 13:27:13 <chanakya_vc> bradfa,Could you give me some examples of codes that implement the Bitbanging in SPI.
May 25 13:27:14 <chanakya_vc> ?
May 25 13:27:18 <chanakya_vc> Like links
May 25 13:27:20 <bradfa> chanakya_vc: please just be sure to submit a progress report on what you've been doing each week, including this week
May 25 13:27:55 <chanakya_vc> bradfa, Ohh one is due today isn't it?I totally forgot :(
May 25 13:28:22 <bradfa> chanakya_vc: you can host your weekly progress reports on a blog but also please mail them to the beagle-gsoc list
May 25 13:28:55 <bradfa> chanakya_vc: one sec, I'll find an example of bitbanging SPI
May 25 13:29:22 <chanakya_vc> bradfa, I need to write one today itself right?I will work on it right-away then.Or is this week not counted?
May 25 13:30:22 <bradfa> chanakya_vc: this week rquires a status report
May 25 13:30:31 <bradfa> chanakya_vc: this is the first week of "official" coding time
May 25 13:30:51 <bradfa> chanakya_vc: you have exams, so mdp and myself are understanding that you cannot spend much time on gsoc, but you still need to do the status report
May 25 13:31:16 <bradfa> chanakya_vc: you are making some progress, so report on what you've done and what issues you see coming
May 25 13:31:37 <chanakya_vc> Okay I will.But I haven't really worked on the actual code itself?Should I write about the PRU hello world and setting up the dev environment?
May 25 13:31:42 <bradfa> chanakya_vc: the linux spi gpio bitbanging is not the easiest to read code, but it may provide some insights (the comments are decent): https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/spi/spi-gpio.c
May 25 13:32:21 <bradfa> chanakya_vc: yes, write up what you've done even if it's not actual code towards your project, setting up the dev environment and getting all the equipment you need is important to document taht you have it and you're ready
May 25 13:33:40 <bradfa> chanakya_vc: I think a good outline for a status report would be like: 1. this is what I did the past week 2. this is what I plan to do in the coming week 3. these are the issues I experienced and how I solved them (or didn't solve them) 4. these are the issues I see coming up in the next week 5. links to the things you've completed
May 25 13:34:09 <bradfa> for number 5, that would be like code or pictures or videos showing off
May 25 13:34:29 <bradfa> or mailing list emails
May 25 13:36:08 <chanakya_vc> bradfa,I won't have the time to put videos and photos.But please do excuse me this time if the report is not upto the mark. I assure you that this won't be the case from next time
May 25 13:36:26 <bradfa> chanakya_vc: we understand
May 25 13:38:04 <chanakya_vc> bradfa,Thanks. I will get to the report at once.Meet you in about two and a half hours. : )I have got to sleep for a bit after that.Haven't slept the entire night : )
May 25 13:38:22 <bradfa> chanakya_vc: sounds good :)  sleep can be overrated :)
May 25 14:21:40 <chanakya_vc> bradfa,Is the ml still moderated?I have sent the report.Please do check if it is visible to all.
May 25 14:22:09 <bradfa> chanakya_vc: I received your mail
May 25 14:22:55 <chanakya_vc> bradfa, Okay.It isnot that good.But it's the best I could do in this sleep deprived state :P
May 25 14:23:42 <chanakya_vc> bradfa, Is it necessary to maintain a blog?I have never maintained one before. I guess wordpress is way to go?
May 25 14:24:31 <bradfa> chanakya_vc: that's a good status report :)
May 25 14:24:49 <bradfa> chanakya_vc: I'm not sure if a blog is required, jkridner?
May 25 14:25:00 <bradfa> chanakya_vc: the weekly status reports to the gsoc list are required
May 25 14:26:56 <chanakya_vc> bradfa, I don't have much idea about blogging.But I guess it would be a good way to document the project.
May 25 14:29:08 <bradfa> chanakya_vc: there are many free blog platforms online to choose from, it's worth learning about them and how to use at least one, a blog is a good way to showcase your work/thoughts/etc and can be helpful for getting a job if you write interesting or useful blog posts
May 25 14:30:42 <chanakya_vc> bradfa, I think it would be the easiest to work with wordpress?Later If I go for my own site,I could integrate the blogs with my site on Wordpress.
May 25 14:31:24 <chanakya_vc> bradfa,  I have seen your blogs on your site.Pretty amazing stuff you write!!
May 25 14:31:36 <bradfa> chanakya_vc: thanks :)
May 25 14:31:44 <bradfa> chanakya_vc: I've not been writing much lately :(
May 25 14:32:32 <mdp> bradfa: I like the report format
May 25 14:34:53 <chanakya_vc> bradfa, I am be going to be following your blogs quite regularly now.I learnt a lot from it.Although there is stuff that I donot understand but it is great to read : )
May 25 14:34:59 <chanakya_vc> hey mdp!
May 25 14:36:25 <bradfa> chanakya_vc: some of the stuff I write, I later find out that I'm wrong :)
May 25 14:37:38 <mdp> chanakya_vc: hello!
May 25 14:37:49 <mdp> bradfa: I have the same problem
May 25 14:39:38 <bradfa> mdp: just yesterday I answered a question which only had 2 possible answers incorrectly, twice :)  It's like plugging in USB cables, I can't even get that right until the 3rd try :)
May 25 14:40:25 <mdp> Lol
May 25 14:41:01 <chanakya_vc> bradfa, mdp, I guess that is okay. I like that fact that you experiment with stuff,try out new things and then write about it.
May 25 14:41:28 <chanakya_vc> Infact that is what I strive to emulate.Trying out new stuff and experimenting.
May 25 14:41:34 <mdp> bradfa: I just posted an 8 page analysis to a FOSS list with a recommended path for a PoC to implement. I'm awaiting whatever I misread and misunderstood to be pointed out to me.
May 25 14:42:25 <mdp> chanakya_vc: yeah, it's important to give back to the community...docs/blogs are one big way
May 25 14:43:20 <chanakya_vc> mdp, Do you also blog?Would love to read your blogs too.
May 25 14:58:13 <bradfa> chanakya_vc: mdp has a few things up on http://www.engineersofthecorn.org/ but he needs to blog more :)
May 25 15:00:05 <chanakya_vc> bradfa, Ohh!
May 25 15:00:35 <chanakya_vc> bradfa, I am even Wordpress even a bit annoying to use :P
May 25 15:00:42 <chanakya_vc> *finding
May 25 15:00:49 <bradfa> chanakya_vc: nothing's perfect :)
May 25 15:01:19 <chanakya_vc> bradfa, Haha.True that.
May 25 15:01:47 <bradfa> chanakya_vc: my blog workflow is not exactly stellar, it's here: https://github.com/bradfa/bradfa.github.io and then github renders it into static files to serve
May 25 15:02:33 <bradfa> chanakya_vc: my blog uses https://jekyllrb.com/
May 25 15:02:34 <m_w> I should probably start a blog again. I keep starting them and deleting them. The last one I has was called "sudo rm -rf /" and you can guess what happened to that one.
May 25 15:02:47 <bradfa> m_w: it deleted your EFI firmware? :)
May 25 15:03:03 <chanakya_vc> bradfa, So eventually, do you think I would be able to mainline this project?I mean it would be terrific to do so.My small contribution to Open source.
May 25 15:03:08 <m_w> yeah then I had to delete it
May 25 15:03:14 <chanakya_vc> bradfa, I will check that out.
May 25 15:03:29 <bradfa> chanakya_vc: the goal should be to mainline it, yes
May 25 15:03:35 <chanakya_vc> m_w, Why did you chose such a name? : )
May 25 15:04:02 <chanakya_vc> rm -rf
May 25 15:04:03 <m_w> chanakya_vc: it was about starting from scratch
May 25 15:04:17 <m_w> ;)
May 25 15:04:27 <chanakya_vc> m_w, Ohh!
May 25 15:04:30 <ZeekHuge> m_w: there was a typo in the mail, sorry.
May 25 15:04:44 <bradfa> chanakya_vc: my quip about EFI deletion is due to: https://github.com/systemd/systemd/issues/2402
May 25 15:05:24 <m_w> ZeekHuge: it happens
May 25 15:06:04 <chanakya_vc> bradfa, I just wanted to ask out of pure curiosity,I read online that in the latest release of the linux kernel,the init system is systemd right?So I read a lot of reviews and some people were unhappy about it.
May 25 15:06:16 <chanakya_vc> Systemd implements parallel processing right?
May 25 15:06:44 <chanakya_vc> So does it make the system faster in comparision to upstart?
May 25 15:06:59 <bradfa> chanakya_vc: linux kernel and choice of init system are not tied together, there are many init systems which can be used
May 25 15:07:40 <bradfa> chanakya_vc: some people say that systemd makes boot time faster than sysvinit, but many of systemd's goals are very similar to those of upstart or launchd or openrc.  All have their good points and bad points
May 25 15:08:08 <bradfa> chanakya_vc: many linux distributions have moved to using systemd as the default init system, lately
May 25 15:08:30 * bradfa runs systemd on his desktop now, has no major gripes with it
May 25 15:09:00 <bradfa> current project I'm starting on will likely use runit as the init and daemon monitor due to size, features, and dependencies of the software
May 25 15:11:00 <chanakya_vc> Ohh.Again out of the very basic knowledge of OS that I have,so systemd is implementing parallel processing via threads?Employing something similar to the algorithms that are employed there?
May 25 15:11:05 <chanakya_vc> bradfa, ^^
May 25 15:11:58 <ZeekHuge> Oh and thank you m_w ! for all that help with the compilation process.
May 25 15:12:48 <chanakya_vc> ZeekHuge, Hey!
May 25 15:12:53 <m_w> http://linoxide.com/linux-how-to/systemd-boot-process/
May 25 15:12:54 <ZeekHuge> Hey !
May 25 15:13:01 <m_w> ZeekHuge: no problem
May 25 15:13:28 <chanakya_vc> ZeekHuge, Thanks for informing about the issue.Though I got my BBB today itself!
May 25 15:14:45 <ZeekHuge> yep, I too received it today. Though its at my relative's house. Will get it soon :)
May 25 15:16:48 <chanakya_vc> ZeekHuge, Ohh.But I haven't still not received the stuff from Google though.
May 25 15:17:32 <chanakya_vc> m_w, It does talk about using control groups instead of PID's to track the different processes.
May 25 15:17:55 <ZeekHuge> were you asked about the KYC forms ? by fedex people ?
May 25 15:17:59 <ZeekHuge> chanakya_vc: ^
May 25 15:18:33 <chanakya_vc> m_w,  So I am assuming that a control group might point to several processes all executing at once.
May 25 15:19:13 <chanakya_vc> ZeekHuge, kyc is only required if we are importing for commercial purpose.In our case an authorization form is all that is required
May 25 15:19:41 <chanakya_vc> Along with residential proof.I gave my voters id card.
May 25 15:21:11 <ZeekHuge> okay.
May 25 15:21:13 <pmezydlo> hi everyone, When GSoC started github update my commit an hour after push lol
May 25 15:21:19 <ZeekHuge> no idea then.
May 25 15:21:56 <m_w> pmezydlo: yikes
May 25 15:23:19 <ZeekHuge> m_w: There were instruction about at-least 4-5 commits/week. What do you think i should commit there ? At present there is nothing that has direct relevance to the project.
May 25 15:24:30 <chanakya_vc> bradfa,I have the same question too?I mean it is highly unlikely that I will finish up a complete part of a code in a day?So I should just push incomplete code?
May 25 15:25:12 <chanakya_vc> bradfa, Some days I might just have to research about what I have to write  so :P
May 25 15:27:50 <m_w> ZeekHuge: documentation perhaps
May 25 15:28:50 <m_w> don't commit broken change just to get more commits
May 25 15:32:26 <m_w> early in a project commits may come in larger chunks.
May 25 15:34:06 <m_w> 4-5 commits a week should be super easy to do
May 25 15:35:08 <ZeekHuge> okay.
May 25 15:36:35 <nerdboy> jkridner: you're right
May 25 15:37:03 <nerdboy> he said he would solder as that looks like the only option for those parts
May 25 15:37:24 <ZeekHuge> also, The KERNEL there at yakbuild/KERNEL, its the patched one, and there in drivers/remoteproc, it has many more things, where as my BBB that is running 4.4.8-ti-r22 only has omap_remoteproc.ko.
May 25 15:37:36 <ZeekHuge> m_w: ^^
May 25 15:38:00 <m_w> ZeekHuge: interesting
May 25 15:38:11 <m_w> reproducible my @$$
May 25 15:38:46 <ZeekHuge> interesting but confusing.
May 25 15:39:12 <m_w> yeah I would talk to rcn and see what he has to say about this
May 25 15:39:20 <ZeekHuge> okay.
May 25 15:42:20 <ZeekHuge> m_w: and now, if we take out that KERNEL separately, and execute make -j4 ARCH=arm LOCALVERSION=-ti-r22 CROSS_COMPILE=gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-, it should generate the exact same kernel that was generated by the build_kernel.sh, right ?
May 25 15:42:53 <m_w> I think so
May 25 15:43:18 <m_w> that is easy enough to verify
May 25 15:43:28 <ZeekHuge> yep, its compiling.
May 25 15:44:54 <nerdboy> jkridner: still looking for a breakout with the righ specs
May 25 15:45:00 <nerdboy> *right even
May 25 15:49:09 <alexhiam> howdy
May 25 15:49:17 <alexhiam> meeting in 11 min??
May 25 15:50:30 <pmezydlo> yes, exactly
May 25 15:50:40 <alexhiam> and only 3 progress reports :(
May 25 15:50:59 <kiran4399> Hi there!!
May 25 15:51:09 <alexhiam> hi kiran4399
May 25 15:51:25 <alexhiam> been traveling and away from irc, how's it going?
May 25 15:52:24 <alexhiam> kiran4399: I assume no emails means no blocking issues? progress report on the way?
May 25 15:55:58 <chanakya_vc> Hey alexhiam !
May 25 15:56:11 <alexhiam> ahoy chanakya_vc
May 25 15:56:40 * alexhiam is in a car headed to the airport, so connection may not be the best...
May 25 15:56:46 <amragaey> hi alexhiam
May 25 15:56:55 <amragaey> hi jkridner
May 25 15:57:16 <amragaey> meeting in 4 mins
May 25 15:57:17 <alexhiam> hi amragaey
May 25 15:57:48 <_av500_> aloo
May 25 15:58:15 <alexhiam> chanakya_vc, pmezydlo, ZeekHuge: thanks for the progress reports
May 25 15:59:46 <pmezydlo> no problem
May 25 16:00:03 <ds2> H,,,,
May 25 16:00:09 <bradfa> chanakya_vc: just keep it within reason for commits.  don't commit things that are broken (as stated by others) but try to have at least 4 days per week where you have commits so that it's clear to everyone that you're making progress on code
May 25 16:00:23 <m_w> :)
May 25 16:01:14 <bradfa> chanakya_vc: and if you have broken things, or just stuff you're trying out, codewise, you can push those commits as a "wip" (work in progress) branch to your github so that it's clear you're doing things but you just aren't yet sure if it'll work or not (this is a very common way to work)
May 25 16:01:24 <jkridner_> I'm out today.
May 25 16:01:38 <jkridner_> Email me if you need something.
May 25 16:02:25 <alexhiam> we really need those reports in before the meeting! (meaning, like, a day before so we have time to read them!!)
May 25 16:02:40 * nerdboy looks around for the Start gong
May 25 16:02:43 <_av500_> I said *tuesday* for a reason
May 25 16:03:00 <_av500_> nerdboy: the gong is at the traditional 5 past
May 25 16:03:35 <ZeekHuge> alexhiam: No problem :)
May 25 16:04:16 <alexhiam> the progress reports are a GSoC requirement, so missing that deadline is not a great thing to do if you want to continue GSoC....
May 25 16:04:59 <alexhiam> and if there's a reason you can't get it posted in time we need to hear about that in advance
May 25 16:05:30 <nerdboy> should tag then too
May 25 16:05:39 <nerdboy> *group posts
May 25 16:06:36 <_av500_> so
May 25 16:06:39 <_av500_> 0) WELCOME
May 25 16:07:08 <_av500_> 0.42) student count

May 25 16:09:25 <nerdboy> i swear it's just like keeping all 4 kitties and trying to "herd"...
May 25 16:09:41 <_av500_> chanakya_vc: kiran4399: ping
May 25 16:09:48 <m_w> wake up!!!
May 25 16:09:52 <Visaoni> ds2: CA
May 25 16:10:00 * nerdboy not even sure how to feed 5 cats...
May 25 16:10:11 <_av500_> chanakya_vc: kiran4399: ping
May 25 16:10:34 <ds2> nerdboy: herd them into an aviary? :D
May 25 16:10:45 <_av500_> sigh
May 25 16:10:52 <nerdboy> the "back yard"?
May 25 16:10:56 <_av500_> chanakya_vc: kiran4399: ping
May 25 16:11:01 <chanakya_vc> hi _av500_ !!
May 25 16:11:05 <_av500_> 6
May 25 16:11:13 <_av500_> chanakya_vc: connection problems?
May 25 16:11:31 <nerdboy> we have a lot fewer birds/lizards/gophers than we did a few months ago...
May 25 16:11:38 <chanakya_vc> Sorry. I was paying attention to my laptop. Studying.Lost track of time
May 25 16:11:43 <chanakya_vc> *not
May 25 16:11:43 <_av500_> ok
May 25 16:11:50 <pmezydlo> m_w: I wrote a simple application for testing. Add a rule to the makefile and spoil linux-headers. Unfortunately, travis shows that it is not ok. I'll fix it. I wanted to overtake the question: why not build.
May 25 16:11:53 <_av500_> nerdboy: please keep the cats for after the meeting
May 25 16:12:02 <_av500_> pmezydlo: shh
May 25 16:12:08 <pmezydlo> sorry
May 25 16:12:13 <nerdboy> did you gong yet?
May 25 16:12:16 <_av500_> ok, no idea where kiran4399 is
May 25 16:12:25 <_av500_> 6 people here and hopefully listening
May 25 16:12:31 <alexhiam> maybe kiran4399 ran away to post a progress report...
May 25 16:12:44 <nerdboy> ^^ optimist
May 25 16:12:56 <_av500_> so, first half-week is over
May 25 16:13:06 <_av500_> hope everybody had a good start
May 25 16:13:19 <_av500_> 1) progress reports
May 25 16:13:25 <_av500_> the due date is tuesday
May 25 16:13:30 <_av500_> pick a time zone, but tuesday
May 25 16:13:41 <_av500_> mars does not count
May 25 16:14:06 <alexhiam> 24hr before meeting works in all timezones
May 25 16:14:10 <_av500_> pmezydlo: chanakya_vc: ZeekHuge Visaoni henrix_ amragaey: tuesday?
May 25 16:14:15 <_av500_> pmezydlo: chanakya_vc: ZeekHuge Visaoni henrix_ amragaey: OK?
May 25 16:14:20 <ds2> tz(Dateline - dX miles) :D
May 25 16:14:22 <ZeekHuge> yes. okay.
May 25 16:14:26 <Visaoni> sure
May 25 16:14:30 <amragaey> ok
May 25 16:14:36 <henrix_> yes
May 25 16:14:47 <chanakya_vc> Yes sure.So every tuesday the report for the previous week right?
May 25 16:14:56 <_av500_> yes
May 25 16:15:06 <_av500_> from tuesday to tuesday
May 25 16:15:09 <pmezydlo> yes
May 25 16:15:19 <nerdboy> pretty sure you don't want me showing up to "supervise"...
May 25 16:15:29 <_av500_> so we have time to read them
May 25 16:15:39 <henrix_> sorry, thought the first progress report should be published on next tuesday
May 25 16:15:47 <_av500_> henrix_: ok
May 25 16:15:54 <_av500_> it was only 2 days
May 25 16:16:00 <henrix_> yes
May 25 16:16:05 <ZeekHuge> yes, thats why.
May 25 16:16:10 <_av500_> so, I hope to see 7 reports new tuesday
May 25 16:16:12 <amragaey> I thought that do, I also apologize for that
May 25 16:16:14 <_av500_> nex*
May 25 16:16:16 <_av500_> np
May 25 16:16:17 <ZeekHuge> anyways. Tuesday.
May 25 16:16:38 <alexhiam> plus the 4 left this week ASAP
May 25 16:17:16 <_av500_> if not much happened in three days, the report will be short
May 25 16:17:53 <nerdboy> "i ate a donut"  <=  too short
May 25 16:18:09 <_av500_> a chocolate donut, with sprinkles
May 25 16:18:23 <_av500_> anyway, next week for real
May 25 16:18:26 <chanakya_vc> _av500_, I will be working in full force from friday. So my report might be a bit short.But it's going to be what you would expect from the next to next tuesday onwarsd
May 25 16:18:28 <_av500_> next ... tuesday :)
May 25 16:18:36 <_av500_> chanakya_vc: ok
May 25 16:18:41 <alexhiam> short report >> no report
May 25 16:19:56 <chanakya_vc> Got it alexhiam _av500_
May 25 16:20:01 <_av500_> ok, lets move on
May 25 16:20:21 <_av500_> 2) standups
May 25 16:20:40 <_av500_> what we did the past years in these meetings was that 2 students got about 5 min for a report here
May 25 16:20:51 <_av500_> just a brief "this is where I am"
May 25 16:21:13 <_av500_> "this is the cool thing I did this week"
May 25 16:21:37 <_av500_> since you are 7 it takes ~4 weeks for all to present
May 25 16:21:46 <_av500_> so we can do it 2x
May 25 16:21:51 <_av500_> thats what we did the past years
May 25 16:22:07 <_av500_> its really short, no need to introduce the project
May 25 16:22:14 <_av500_> just dive in where you are now
May 25 16:22:53 <ZeekHuge> so the 4 students ?
May 25 16:23:03 <_av500_> 7?
May 25 16:23:09 <_av500_> 2 students per meeting
May 25 16:23:17 <_av500_> roughly
May 25 16:23:32 <ZeekHuge> okay. and for today, those 2 are ?
May 25 16:23:36 <_av500_> nobody
May 25 16:23:40 <_av500_> you just started
May 25 16:23:46 <_av500_> I'm just telling you in advance
May 25 16:23:52 <chanakya_vc> ZeekHuge, Next meeting :P
May 25 16:23:55 <pmezydlo> I want presentation on next meeting
May 25 16:23:57 <_av500_> I would start it next week or the one after
May 25 16:24:04 <_av500_> pmezydlo: fine, you got it
May 25 16:24:12 <ZeekHuge> okay.
May 25 16:24:15 <_av500_> as said, do not prepare slides
May 25 16:24:23 <_av500_> and you can dive in directly
May 25 16:24:44 <_av500_> we are all "technical" here :)
May 25 16:24:53 <pmezydlo> all on irc?
May 25 16:24:59 <_av500_> yes, here in the meeting
May 25 16:25:35 <pmezydlo> ok
May 25 16:26:09 <_av500_> one more volunteer for next week?
May 25 16:26:31 <henrix_> ok
May 25 16:27:08 <_av500_> ok, ZeekHuge and henrix_
May 25 16:27:14 <_av500_> er
May 25 16:27:18 <_av500_> pmezydlo and henrix_
May 25 16:27:47 <_av500_> ok, moving on
May 25 16:28:02 <_av500_> 3) anything I forgot?
May 25 16:28:09 <ZeekHuge> Cool hardware
May 25 16:28:21 <ZeekHuge> ahh .. *hardware
May 25 16:28:23 <_av500_> jkridner: how are we on shipping?
May 25 16:28:50 <alexhiam> _av500_: jkridner said he's not here today
May 25 16:28:53 <chanakya_vc> _av500_, I received my BBB !
May 25 16:28:59 <_av500_> chanakya_vc: good
May 25 16:29:03 <ds2> who's shortofwhat HW?
May 25 16:29:05 <ZeekHuge> I too .
May 25 16:29:15 <amragaey> I didn
May 25 16:29:17 <ZeekHuge> me - ADC EVM
May 25 16:29:19 <amragaey> t
May 25 16:29:50 <amragaey> there's something wrong with fedex facility here, i'm on contact with them
May 25 16:30:17 <ds2> ZeekHuge: giving up on what you have or you found a solutionfor the clock?
May 25 16:31:29 <m_w> is the internet broken?
May 25 16:31:38 <pmezydlo> yes
May 25 16:32:01 <pmezydlo> but now is ok
May 25 16:32:18 <m_w> how about you ZeekHuge?
May 25 16:32:29 <ZeekHuge> ah, I am not sure, but can we use a fast OP-amp ? in front of the clock ? and then terminate it .
May 25 16:32:34 <ZeekHuge> ds2: ^^
May 25 16:32:38 <ZeekHuge> mine is fine.
May 25 16:33:05 <ZeekHuge> like a schmitt trigger ?
May 25 16:33:59 <Abhishek__> Hmm
May 25 16:34:01 <alexhiam> what's the clock issue? (maybe after the meeting is better)
May 25 16:34:06 <ZeekHuge> makes sense ?
May 25 16:34:36 <_av500_> ZeekHuge: is wating for ADC EVM
May 25 16:34:40 <ds2> ZeekHuge:what isthe quickest and least HW. GSoC is a SW project
May 25 16:34:42 <_av500_> everybody else has a BBB?
May 25 16:34:55 <_av500_> amragaey fights with fedex
May 25 16:35:10 <pmezydlo> yes now I have 3
May 25 16:35:15 <nerdboy> gotta have the *right* hardware...
May 25 16:35:19 <ZeekHuge> okay. I have a BBB.
May 25 16:35:30 <chanakya_vc>  Me too
May 25 16:35:34 <_av500_> ok
May 25 16:35:48 <_av500_> you know the drill, anything blocking you, shout out!
May 25 16:35:57 <m_w> we can discuss the clock after the meeting
May 25 16:36:00 <amragaey> _av500_, it's 3 weeks now, I'm waiting for answer tomorrow
May 25 16:36:06 <_av500_> ok
May 25 16:36:24 <_av500_> :(
May 25 16:36:49 <alexhiam> amragaey: is there somewhere more local you could order one from if that doesn't work out?
May 25 16:38:02 <amragaey> alexhiam, ehab former GSOC told me that he didn't find it anywhere last year.. so I will have to order it online
May 25 16:38:57 <alexhiam> amragaey: you said you were borrowing ehab's for now though, right?
May 25 16:39:03 <nerdboy> the mockingbirds have been harassing the kitties all mtg
May 25 16:39:20 <nerdboy> so yeti just caught one
May 25 16:39:49 <amragaey> alexhiam, yes but seems he didn't like me to update the kernel :)
May 25 16:40:14 <m_w> dude, image the thing and overwrite it
May 25 16:40:39 <alexhiam> byosd (bring your own SD card)
May 25 16:41:30 <chanakya_vc> _av500_, Is that all for the meeting .Can I leave? Got to study for an exam.If nothing more is to be discussed?
May 25 16:41:32 <amragaey> Can I use this kernel image on my own SD ?
May 25 16:43:09 <_av500_> chanakya_vc: ok, go :)
May 25 16:43:21 <alexhiam> amragaey: for sure
May 25 16:43:46 <alexhiam> k, I'm at the airport, gotta run
May 25 16:43:56 <amragaey> OK, i'll do that
May 25 16:44:12 <chanakya_vc> Thank you _av500_! : )
May 25 16:44:15 <alexhiam> thanks _av500_
May 25 16:44:25 <kiran4399> _av500_: I am sorry..
May 25 16:44:37 <ZeekHuge> good luck chanakya_vc :)
May 25 16:45:01 <_av500_> kiran4399: alarm did not sound?
May 25 16:45:07 <chanakya_vc> bradfa, mdp , I will catch up with you on friday night or definitely with a mail on Saturday morning.
May 25 16:45:10 <kiran4399> alexhiam: I am sorry..
May 25 16:45:32 <chanakya_vc> ZeekHuge, Thanks. Bye : )
May 25 16:45:43 <kiran4399> _av500_: I am sorry.. just got into something..
May 25 16:46:00 <kiran4399> _av500_: I am writing the progress report..
May 25 16:46:09 <_av500_> better late than never
May 25 16:46:18 <_av500_> for next week, it's tuesday for the report
May 25 16:46:22 <_av500_> and for every following week
May 25 16:46:29 <_av500_> kiran4399: you have hardware?
May 25 16:47:12 <kiran4399> _av500_: not yet.. but I think it would be home by tomorrow.. I anyway have my bb black..
May 25 16:47:53 <kiran4399> _av500_: sort of got stuck in some custom clearance 5 days before which I cleared it..
May 25 16:48:34 <_av500_> kiran4399: ok
May 25 16:49:46 <ZeekHuge> meeting done ?
May 25 16:52:05 <_av500_> more or less
May 25 16:52:09 <_av500_> thansk for attending
May 25 16:52:13 <_av500_> go code!
May 25 16:52:18 <_av500_> see you next week
May 25 16:52:24 <_av500_> see your reports next tuesday
May 25 16:52:32 <ZeekHuge> :) sure . Thank you _av500_
May 25 16:52:36 <_av500_> see you here in the channel all the time
May 25 16:52:46 <_av500_> and have fun
May 25 16:52:57 <m_w> okay so lets take care of those questions pmezydlo and ZeekHuge
May 25 16:52:57 <ds2> m_w, ZeekHuge: on the issue of clocking....
May 25 16:53:05 <ZeekHuge> okay so clock.
May 25 16:53:10 <ZeekHuge> yes.
May 25 16:53:20 <ZeekHuge> So that makes sense ?
May 25 16:53:21 <amragaey> well, thanks _av500_ I may post my progress by two days
May 25 16:53:48 <m_w> don't like my hack that I send via email?
May 25 16:54:19 <henrix_> ok, thanks
May 25 16:54:19 <ds2> m_w: which is your hack? remove part or ?
May 25 16:54:30 <m_w> the schematic
May 25 16:54:33 <ZeekHuge> m_w: directly connecting the pru pin to the clock ?
May 25 16:54:46 <ZeekHuge> and removing all those components there ?
May 25 16:54:51 <m_w> yeah
May 25 16:55:09 <ds2> ZeekHuge: can you do that rework reliably?
May 25 16:55:27 <kiran4399> All the best for everyone!!
May 25 16:55:44 <ZeekHuge> zmatt said that its difficult to say if pru generated clock will be clean enough.
May 25 16:55:58 <ZeekHuge> the problem according to him lies with the BBB
May 25 16:56:09 <ZeekHuge> and not specifically with the PRUs
May 25 16:56:15 <ds2> ZeekHuge: do you know what he meant by "clean enough"?
May 25 16:56:30 <ds2> jitter? bounce (over/undershoot)? other?
May 25 16:56:50 <ZeekHuge> I gave him the link to the data sheet, and the EVM.
May 25 16:57:04 <ZeekHuge> and he read it.
May 25 16:58:37 <ds2> yes but what did he mean by that?
May 25 16:59:08 <ZeekHuge> 22 16:14:18 <ZeekHuge>	a terminated line being toggled by pru would be a clean enough clock source. isnt it ?
May 25 16:59:09 <ZeekHuge> May 22 16:14:35 <zmatt>	hard to say
May 25 16:59:09 <ZeekHuge> May 22 16:15:07 <zmatt>	the output drivers aren't very strong, and there's plenty of opportunity for noise to couple onto it
May 25 16:59:09 <ZeekHuge> May 22 16:15:19 <zmatt>	a bigger problem probably it not the am335x not the bbb
May 25 16:59:09 <ZeekHuge> May 22 16:15:31 <zmatt>	*but the bbb
May 25 16:59:39 <m_w> really?!?
May 25 17:00:06 <ds2> first comment won't apply if I understand m_w's hack
May 25 17:00:26 <m_w> is he saying the bbb is routed poorly?
May 25 17:00:37 <ZeekHuge> I think so.
May 25 17:00:53 <ds2> not so much poorly as much as it wasn't design for it
May 25 17:01:05 <ds2> the PRU on LCD pins may help
May 25 17:01:20 <ds2> BUT it has branching... saving thing is it has source termination
May 25 17:01:59 <ds2> and it isn't helping that you are doing long wires
May 25 17:02:19 <ds2> ZeekHuge: do you have thin pieces of coax? (thinner then RG58)
May 25 17:02:32 <pmezydlo> m_w: everything is ok, just me is not build, I will fix it in an hour.  I have to go now, I'll be later
May 25 17:02:47 <m_w> pmezydlo: okay thanks
May 25 17:02:57 <ZeekHuge> i dont think so.
May 25 17:03:03 <ZeekHuge> but I can get it.
May 25 17:03:42 <m_w> what frequency are we looking to drive the clock?
May 25 17:03:46 <ds2> m_w: are you an analog engineer? (tryingt o see what skills we have here)
May 25 17:03:56 <ZeekHuge> max 20MHz
May 25 17:03:58 <m_w> I have some analog experience
May 25 17:04:08 <m_w> a little RF lately
May 25 17:05:02 <ds2> 20MHz? I would do this - get buffer that can drive 50ohm keep the BBB - buffer wires as short as possible. Have the bffer drive coax and be done with
May 25 17:05:16 <m_w> yeah
May 25 17:05:26 <ds2> otherwise, do m_w's rework if you can keep the wiring under a few inches
May 25 17:05:43 <ZeekHuge> okay.
May 25 17:05:51 <ds2> wires == more capacitance/inductance which means they need more power. keeping htem short reduces that
May 25 17:06:06 <ds2> m_w: 'k we are in the same boat :/
May 25 17:06:39 <ZeekHuge> so, what about noises from the gpo ?
May 25 17:06:41 <m_w> I think that using a buffer is okay
May 25 17:07:16 <ZeekHuge> okay so i guess, it wont make difference at 20Mhz ?
May 25 17:08:03 <ds2> 20MHz is on the order of the PCLK for a VGA display
May 25 17:08:14 <m_w> can we use an external oscillator?
May 25 17:08:23 <ds2> so given that - 2-3 inches is tolerated
May 25 17:08:30 <ZeekHuge> okay.
May 25 17:08:33 <m_w> or function generator?
May 25 17:08:38 <ds2> m_w: that would make the PRU code harder (async clock)
May 25 17:08:47 <m_w> that is true
May 25 17:08:51 <ZeekHuge> yes.
May 25 17:09:00 <ZeekHuge> though we could use 16 bit capture mode
May 25 17:09:00 <m_w> the syncronization would be difficult
May 25 17:09:06 <ds2> I have gone down that path with video input. it is no fun
May 25 17:09:09 <ZeekHuge> bit it would still be difficult
May 25 17:09:13 <ds2> ZeekHuge: doesn't help that much
May 25 17:09:20 <ZeekHuge> yep
May 25 17:10:04 <m_w> what kind of buffers can you get a hold of?
May 25 17:10:52 <ZeekHuge> opamp ?
May 25 17:10:54 <ds2> 50ohm drivers can be a pita to source
May 25 17:10:55 <ZeekHuge> LM324
May 25 17:11:08 <ZeekHuge> dont know the slew rate and all of that
May 25 17:11:11 <ds2> ZeekHuge: the GBW of the 324 is too small for a 20MHz signal
May 25 17:11:12 <ZeekHuge> will have to check
May 25 17:11:18 <ZeekHuge> okay
May 25 17:11:25 <ds2> and the 324 doesn't have drive strength for 50ohm
May 25 17:11:49 <ds2> I wonder if the classic video amps can do it
May 25 17:12:10 <ds2> but please keep this in mind - we cannot spend too much time on the HW. GSoC is not a HW program
May 25 17:12:40 <ZeekHuge> okay. will note that
May 25 17:13:00 <ds2> that is coming from the loads and masters of the GSoC program
May 25 17:13:13 <ZeekHuge> and then back to the kernel side
May 25 17:13:16 <ZeekHuge> the source.
May 25 17:13:40 <ZeekHuge> how to reproduce an exact copy of the known kernel image.
May 25 17:13:44 <ZeekHuge> oh yes
May 25 17:13:57 <ds2> find the source and build it? :D
May 25 17:14:00 <ZeekHuge> m_w: is going to discuss it with rcnee
May 25 17:14:04 <ds2> or you mean the BB logic stuff?
May 25 17:14:30 <ZeekHuge> no, the source for the kernel image 4.4.8-ti-r22
May 25 17:14:54 <ds2> ah
May 25 17:15:12 <ds2> try that and let us know if it is going no where
May 25 17:15:24 <ZeekHuge> okay.
May 25 17:15:40 <ds2> btw - do you know what signals needs to be toggled to get the ADC to return a sample on the parallel bus?
May 25 17:17:06 <ZeekHuge> yes. I discussed it with Wormo.
May 25 17:17:27 <ZeekHuge> just a second let me open up the dsheet
May 25 17:17:41 <ZeekHuge> http://cds.linear.com/docs/en/datasheet/223876fa.pdf
May 25 17:18:42 <ZeekHuge> page 23
May 25 17:19:15 <ZeekHuge> so it is '3201S-40G1' connector pru will be connected to.
May 25 17:19:31 <ZeekHuge> and most of them are GND, while others are data pins
May 25 17:19:58 <ZeekHuge> pin 1 and 2 are to the EEPROM for auto detection kind of thing.
May 25 17:20:27 <ZeekHuge> so ignoring them for now
May 25 17:20:43 <m_w> can we use discrete transistors for the clock buffer?
May 25 17:20:59 <ZeekHuge> then, pin number 3 will have the sampling clock so we can use 16 bit capture mode.
May 25 17:21:06 <ds2> m_w: what configuration?
May 25 17:21:35 <m_w> Emitter follower maybe
May 25 17:21:52 <ZeekHuge> pin number 39 will will be connected to VCC
May 25 17:22:19 <ZeekHuge> so as to enable the buffer 74VCX16373MTD
May 25 17:24:51 <ds2> emitter follower could work... just need to work base capacitance and have the right bias resistor
May 25 17:25:02 <ZeekHuge> and then pin 5 will also be ignored in the starting. Its about overflow and underflow.
May 25 17:25:02 <ds2> I used it as a quick buffer for analog video input
May 25 17:25:50 <ds2> ZeekHuge: can you draw it out and maybe toss it on your blog?
May 25 17:26:08 <ds2> sorry, but I need to run
May 25 17:26:22 <ZeekHuge> okay.
May 25 17:26:38 <m_w> me too
May 25 17:26:49 <ZeekHuge> will do.
May 25 17:26:52 <ZeekHuge> thank you :)
May 25 17:26:56 <m_w> no prob
May 25 17:27:22 <ZeekHuge> ds2: m_w anything about the plans in the report ?
May 25 17:27:56 <m_w> they look good
May 25 17:27:59 <ZeekHuge> Abhishek__: ^^
May 25 17:28:16 <m_w> email if in a pinch
May 25 17:28:24 <ZeekHuge> Sure :)
May 25 21:37:11 <ds2> Hmmm
