**** BEGIN LOGGING AT Tue May 24 02:59:58 2016
May 24 03:55:55 <ZeekHuge> Hey m_w , ds2 !
May 24 03:56:08 <ZeekHuge> That thing about J3
May 24 03:57:01 <ZeekHuge> So, at first, I had impression that max V on the clock should be 2.0V, but I was wrong, as there is that inverter too. so, we dont need a voltage divider.
May 24 03:57:34 <ZeekHuge> then, since a voltage divider is not needed, the line can be terminated using a series 50 Ohm resistor.
May 24 03:58:02 <ZeekHuge> That will be about 17-18 mA . and I think that is tolerable.
May 24 03:58:45 <ZeekHuge> (not sure, I had an impression that 30-40 mA is also okay for most of the embedded systems ).
May 24 04:00:54 <m_w> are you talking a 50 ohm series termination resistor?
May 24 04:01:51 <ZeekHuge> but, I had a discussion on it with zmatt, at #beagle. he first agreed at using resistor termination. But then advice to use a proper filter and then a squaring circuit, even when i am using the PRU to drive the clock, that would already produce a pulse train. So he was basically not sure about the clock from pru being clean, mainly because of the BBB.
May 24 04:02:09 <ZeekHuge> Yes 50 ohm series termination.
May 24 04:02:31 <ZeekHuge> that would not consume current ? hi-Z ?
May 24 04:02:36 <m_w> then the current draw should not apply
May 24 04:02:53 <ZeekHuge> yes, so, hi-Z
May 24 04:03:07 <m_w> to GND yes
May 24 04:03:44 <ZeekHuge> so how should i finally go with it ?
May 24 04:03:47 <ZeekHuge> ds2: ^^
May 24 04:03:52 <ZeekHuge> m_w: ^^
May 24 04:04:49 <m_w> series termination is usually applied near the driving side of the signal
May 24 04:05:14 <ZeekHuge> so that would be on the pru ?
May 24 04:05:23 <m_w> so closer to the IO on the BBB would be more effective
May 24 04:05:30 <ZeekHuge> okay.
May 24 04:05:38 <ZeekHuge> will that work ?
May 24 04:05:49 <m_w> but I dont know how you are going to connect it
May 24 04:06:35 <ZeekHuge> perfboard ?
May 24 04:06:45 <m_w> what are you using to adapt the BBB headers to the ADC header?
May 24 04:07:17 <ZeekHuge> a perfboard with male and female headers . so as to connect them ..
May 24 04:07:49 <ZeekHuge> but, the clock signal would be separate.
May 24 04:08:07 <ZeekHuge> away from these digital io.
May 24 04:08:33 <m_w> yeah that will be tricky
May 24 04:09:10 <ZeekHuge> m_w: do you know if the ADC has even been shipped ?
May 24 04:09:41 <m_w> I do not really know
May 24 04:09:50 <m_w> lemme look at the shipping spreadsheet
May 24 04:11:11 <ZeekHuge> okay.
May 24 04:11:20 <m_w> it looks like jkridner only shipped the BBB
May 24 04:11:32 <m_w> did you receive that?
May 24 04:11:42 <ZeekHuge> BBB not yet.
May 24 04:12:33 <ZeekHuge> okay so since the ADC is not yet shipped, as it seems, I will be working on the software for this weak.
May 24 04:12:57 <ZeekHuge> And main goal will be to get beaglelogic working. and get hands on the latest remoteproc drivers.
May 24 04:13:04 <ZeekHuge> Sounds okay ?
May 24 04:13:05 <m_w> yeah that is good idea
May 24 04:13:07 <ZeekHuge> m_w: ^^
May 24 04:13:12 <ZeekHuge> cool
May 24 04:13:33 <ZeekHuge> so, I was compiling the source as is said here : https://github.com/RobertCNelson/ti-linux-kernel-dev/tree/4.4.8-ti-r22
May 24 04:13:49 <m_w> ask about the hardware on the Wednesday if you don't find anything out before then
May 24 04:13:52 <ZeekHuge> I am using kernel image - 4.4.8-ti-r22
May 24 04:14:00 <m_w> okay
May 24 04:14:00 <ZeekHuge> yep :)
May 24 04:14:47 <ZeekHuge> So i have cloned linux-torvalds and executing the ./build_kernel thing
May 24 04:14:59 <m_w> okay
May 24 04:15:43 <m_w> it worked for you?
May 24 04:16:26 <ZeekHuge> and a configuration option appears, its probably the linux-torvalds configuration ie it seems the patches are not yet applied, as the remoteproc configuration option is almost empty.
May 24 04:16:41 <ZeekHuge> so, do i need to change something in the configuration ?
May 24 04:17:51 <ZeekHuge> or can i find the exact .config file for a kernel version.
May 24 04:18:41 <m_w> well the torvalds tree does not have all of the remoteproc patches
May 24 04:18:52 <m_w> this is mainline
May 24 04:19:14 <ZeekHuge> https://tmate.io/t/ro-Mu2UbbxpV7INmIcBOZowKUS40
May 24 04:19:18 <ZeekHuge> m_w: ^^
May 24 04:19:22 <m_w> not sure what this script even does
May 24 04:19:34 <ZeekHuge> you at the link ?
May 24 04:19:38 <m_w> yup
May 24 04:20:19 <m_w> 4.6.0 is certainly mainline
May 24 04:20:27 <m_w> look up top
May 24 04:21:09 <m_w> it looks to not be configured
May 24 04:22:36 <m_w> you need to clone the appropriate tree
May 24 04:23:04 <ZeekHuge> the script automatically wanted that tree.
May 24 04:23:23 <ZeekHuge> It was trying to clone it, but was failing, so i manually cloned from the same link
May 24 04:24:21 <m_w> this is a strange creature
May 24 04:24:57 <ZeekHuge> this ?
May 24 04:25:09 <m_w> this set of scripts
May 24 04:25:22 <m_w> can I type on the prompt?
May 24 04:25:33 <ZeekHuge> wait a sec ..
May 24 04:25:33 <m_w> that would be cool
May 24 04:27:45 <ZeekHuge> you there on the link ?
May 24 04:27:52 <ZeekHuge> yes ..
May 24 04:31:11 <ZeekHuge> m_w: the linux-torvals tree that I have also contains the 4.4 tag.
May 24 04:31:30 <ZeekHuge> We can probably use it to create a separate branch and then use that kernel ?
May 24 04:31:59 <m_w> not sure what is going on here
May 24 04:32:10 <ZeekHuge> ahh ?
May 24 04:32:38 <m_w> https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
May 24 04:32:50 * ZeekHuge will be leaving for college in about 10 minutes.
May 24 04:32:54 <m_w> it say it is cloning the stable tree by defualt
May 24 04:33:17 <m_w> but then it say if you have the torvalds tree then use it
May 24 04:33:23 <ZeekHuge> on the terminal please ..
May 24 04:33:26 <m_w> those are two different trees
May 24 04:33:59 <m_w> ha
May 24 04:34:06 <ZeekHuge> so you see there ? it is trying to clone the tree that i have.
May 24 04:34:12 <m_w> yeah
May 24 04:38:20 <m_w> me == confused
May 24 04:39:12 <ZeekHuge> :)
May 24 04:39:27 <ZeekHuge> that is a cool tool anyway, isnt it ?
May 24 04:39:35 <m_w> very
May 24 04:41:12 <ZeekHuge> m_w: I need to leave now. for the college.
May 24 04:41:59 <m_w> oh
May 24 04:42:10 <m_w> okay
May 24 04:42:20 <m_w> I will clone the repo locally and observe
May 24 04:42:24 <ZeekHuge> okay, so closing tmate.
May 24 04:42:28 <ZeekHuge> okay :)
May 24 04:42:46 <m_w> I will report back if I get it to work
May 24 04:48:01 <ZeekHuge> Hi Wormo !
May 24 04:48:10 <ZeekHuge> Will be leaving for college in 5 minutes
May 24 04:48:24 <Wormo> ok, ttyl then
May 24 04:48:57 <ZeekHuge> sure, but updates :
May 24 04:49:07 <ZeekHuge> I got the linux-torvalds tree .
May 24 04:49:23 <ZeekHuge> and edited the system.sh to point towards it.
May 24 04:50:00 <ZeekHuge> so, now, ./build_kernel takes me to the configuration option, and its 4.6
May 24 04:50:32 <ZeekHuge> but the tree has 4.4 and some 4.4.rcX tags, so I can probably use them to get the 4.4 kernel ?
May 24 04:50:38 <ZeekHuge> makes sense ?
May 24 04:50:49 <m_w> no
May 24 04:50:50 <Wormo> I was looking at build_kernel, it didn't seem to have an option to automatically build an earlier version for some reason
May 24 04:51:48 <Wormo> easiest for now would be to let it build what it wants & upgrade the kernel on your SD card to go with the modules
May 24 04:52:21 <m_w> I am running the script now to see what is going on
May 24 04:52:22 <Wormo> I know it's not quite the recommended baseline, but it's a starting point
May 24 04:52:32 <Wormo> ok good
May 24 04:52:39 <ZeekHuge> can't we directly ask rcnee ? through mails ? I have heard he is quite active on emails.
May 24 04:52:43 <m_w> it is cloning the torvalds tree now
May 24 04:53:02 <m_w> now it is clone stable
May 24 04:53:42 <ZeekHuge> Okay leaving now ! Thank you :)
May 24 04:53:48 <Wormo> bye for now ZeekHuge
May 24 04:53:53 <m_w> I will dump the output to email
May 24 04:54:00 <Wormo> cool
May 24 04:54:24 <Wormo> I'm heading out soon myself
May 24 04:55:43 <m_w> well it failed
May 24 05:42:46 <m_w> build from the ti-linux-4.4.y branch worked
May 24 05:43:43 <m_w> git clone https://github.com/RobertCNelson/ti-linux-kernel-dev.git
May 24 05:43:52 <m_w> cd ti-linux-kernel-dev
May 24 05:44:03 <m_w> git checkout ti-linux-4.4.y
May 24 05:44:20 <m_w> cp system.sh.sample system.sh
May 24 05:45:02 <m_w> ./build_kernel.sh
May 24 08:15:21 <Abhishek__> Hey so remoteproc just landed into the 4.4 kernel
May 24 08:15:30 <Abhishek__> ZeekHuge: try it out when you get it
May 24 08:18:41 <Abhishek__> https://github.com/RobertCNelson/ti-linux-kernel/blob/ti-linux-4.4.y/drivers/remoteproc/
May 24 08:20:41 <Abhishek__> https://github.com/RobertCNelson/ti-linux-kernel/tree/ti-linux-4.4.y/drivers/rpmsg
May 24 09:52:10 <ZeekHuge> Hey Wormo ! you still awake ?
May 24 09:52:31 <Wormo> heading out, sent an email just now, finishing one to somebody else...
May 24 09:53:17 <ZeekHuge> yep, that is how i knew that you are still up.
May 24 09:53:30 <Wormo> Did it make sense?
May 24 09:53:40 <Wormo> trying the patch + config on a manual build
May 24 09:55:08 <ZeekHuge> yes, it does. it also need linux-stable na ?
May 24 09:55:56 <Wormo> I assume it goes on top of v4.8.4 tag
May 24 09:56:18 <Wormo> in stable tree
May 24 09:57:00 <Wormo> if not then I guess somebody should ask RCN like you suggested...
May 24 10:01:21 <ZeekHuge> okay, as you suggested in your mail, I should ./build_kernel from the ti-linux-4.4.y branch and then the put the resulting lkm at right position in bbb and load it. correct ?
May 24 10:01:48 <Wormo> No that was suggesting alternative to the build_kernel thing
May 24 10:02:53 <Wormo> just to snag the cloned kernel, check out 4.4.8 again, and manually use 'patch' to apply the diff file downloaded from that url
May 24 10:03:09 <Wormo> and use the kernel config file also at the url
May 24 10:03:36 <ZeekHuge> oh ! okay.
May 24 10:03:59 <Wormo> then when you build the modules, try copying some onto your SD and see if they load fine or complain about mismatches
May 24 10:05:05 <ZeekHuge> so use that defconfig and patch-4.4.8-ti-r22.diff.gz.
May 24 10:05:05 <ZeekHuge> and then build module.
May 24 10:05:08 <ZeekHuge> use these patches on linux-torvalds right ?
May 24 10:05:41 <Wormo> yup with it checked out to v4.4.8
May 24 10:05:46 <ZeekHuge> okay.
May 24 10:05:50 <ZeekHuge> on it.
May 24 10:11:06 <ZeekHuge> it has 4.4-rc8. so using it.
May 24 10:11:23 <Wormo> hm not -rc8 that's different
May 24 10:11:40 <ZeekHuge> there is no v4.4.8
May 24 10:11:48 <ZeekHuge> only v4.4-rcX
May 24 10:12:11 <ZeekHuge> should i come on tmate ?
May 24 10:12:20 <Wormo> I need to get some sleep :/
May 24 10:12:26 <ZeekHuge> okay.
May 24 10:12:32 <ZeekHuge> Good night :)
May 24 10:12:37 <Wormo> otherwise would have been good
May 24 10:12:44 <Wormo> it's 3am-ish now
May 24 10:13:07 <ZeekHuge> yes, I guessed so. Go on ! Have a good night !
May 24 10:13:10 <ZeekHuge> TC
May 24 10:13:26 <ZeekHuge> TC=take care
May 24 10:13:39 <Wormo> thx, later
May 24 10:17:05 <Wormo> maybe you should just dl the 4.4.8 tarball from kernel.org, can do reget so easier than getting the stable git tree
May 24 10:22:12 <Wormo> actually it's even possible that plain 4.4 tag will work, that the patch to .8 is included in the diff
May 24 10:22:31 <Wormo> I didn't look at it carefully enough to be sure...
May 24 10:23:46 <ZeekHuge> I will look into :) you should sleep :)
May 24 16:32:00 <ds2> hmmm
May 24 17:09:07 <nerdboy> all you need is one clone of linux-stable
May 24 17:09:26 <nerdboy> then you can set the path in the rcn build script to point there
May 24 17:59:06 <henrix_> Hi, is there a working device tree for spidev on BB-X15? I want to test the SPI interface before we begin to create an adapter board for expansion header. Or any other advice to test spi?
May 24 18:23:23 <jkridner> nerdboy: can I ship everything to you have have you reship? I wanted to buy 10 of the MA40S4S, MA40S4R for the group.
May 24 18:23:35 <jkridner> Where do I get the ADC?
May 24 18:23:44 <jkridner> In lieu of a Blue, are other sensors needed?
May 24 18:25:32 <jkridner> nerdboy, ds2: I don't see a kit for the ADC: http://www.ti.com/product/ADC08B200/toolssoftware
May 24 18:27:06 <nerdboy> i'm not sure which ADC yet, the one we picked originally was obseleted
May 24 18:28:50 <nerdboy> jkridner: explain the reship thing?  and besides the adc the req is (either blue or black+imu) plus the 4 sonics and one humidity sensor
May 24 18:29:01 <jkridner> I was planning on throwing in 2 BeagleBone Green's into the shipment as well... let me know if it should be more or less.
May 24 18:29:19 <jkridner> MPU-9250?
May 24 18:29:24 <nerdboy> blue has everything but moisture?
May 24 18:29:30 <jkridner> I don't see any humidity sensor on there.
May 24 18:29:35 <jkridner> Blue isn't available.
May 24 18:29:55 <nerdboy> sht20?
May 24 18:29:58 <jkridner> reship thing is I wanted to buy some extra sonic sensors, but didn't want to make a bunch of shipments.
May 24 18:30:26 <nerdboy> you can ship all the crap here if you want
May 24 18:30:33 <jkridner> grrr... no stock on http://www.digikey.com/product-search/en/programmers-development-systems/evaluation-boards-expansion-boards/2622798?k=mpu-9250&k=&pkeyword=mpu-9250&pv1742=463&pv984=13311&FV=fff40028%2Cfff8054e&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25
May 24 18:31:00 <jkridner> how many Greens and how many sonic sensors?
May 24 18:31:51 <jkridner> grrr... http://www.digikey.com/product-detail/en/seeed-technology-co-ltd/101020079/1597-1302-ND/5487426 showed availability and is now gone.
May 24 18:31:52 <nerdboy> what's different on green?  the spreadsheet needs updating too...
May 24 18:33:15 <nerdboy> do we get two complete sets, one for each of us?
May 24 18:34:25 <jkridner> no HDMI
May 24 18:34:45 <jkridner> nerdboy: just tell me the final numbers.
May 24 18:35:07 <jkridner> is a BMP180 useful?
May 24 18:39:01 <nerdboy> that's just pressure?  and also discontinued...
May 24 18:48:13 <jkridner> nerdboy: would dht22 work?
May 24 18:48:40 <jkridner> 2 sets of everything or 3, 4?
May 24 18:51:37 <jkridner> nerdboy: please approve this cart: http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=1f2c9448ed
May 24 18:52:47 <nerdboy> 2 sets of everything, which would be 2 each rec & tx on the transducers
May 24 18:55:00 <nerdboy> jkridner: looks good
May 24 18:55:18 <nerdboy> everything but ADC part...
May 24 18:55:47 <Wormo> which you're picking out now?
May 24 18:59:21 <nerdboy> yup, poking and picking...
May 24 19:00:35 <nerdboy> younger son had last final yesterday
May 24 19:00:55 <nerdboy> might be finals week for visaoni too...
May 24 19:08:33 <Wormo> ZekeHuge has last finals this week too
May 24 19:12:09 <jkridner> Anyone seen ZeekHuge?
May 24 19:12:37 <jkridner> anyone seen chanakya_vc?
May 24 19:13:50 <jkridner> both have actions required to acquire their boards.... I've notified Fedex that I wish to pay all the taxes, but they need to complete forms and their is a deadline or the boards will be sent back.
May 24 19:21:58 <Wormo> I saw ZeekHuge last night
May 24 19:22:04 <Wormo> but not today
May 24 19:22:23 <Wormo> Do you have specifics on that form that I could email him?
May 24 19:22:37 <Wormo> He has been asking about when the boards would arrive
May 24 19:30:08 <pmezydlo> jkridner:today came to me package with a BBB board. thanks
May 24 19:30:42 <jkridner> pmezydlo: great!
May 24 19:31:15 <nerdboy> guess the "bom" turned out more complicated than originally planned...
May 24 19:49:23 <m_w> not seeing any progress reports
May 24 19:59:35 <pmezydlo> I will send in 10-20 minutes
May 24 20:03:34 <m_w> excellent
May 24 20:14:00 <ZeekHuge> Wormo:

May 24 20:15:17 <ZeekHuge> Wormo: ^^
May 24 20:15:32 <ZeekHuge> I was and am sleeping .. almost
May 24 20:16:34 <ZeekHuge> no mail/contact from the fedex side.
May 24 20:18:56 <ZeekHuge> anyone ?
May 24 20:19:10 <ZeekHuge> ds2: nerdboy _av500_ jkridner m_w
May 24 20:19:41 <m_w> jkridner is the one you need to talk to
May 24 20:19:52 <ZeekHuge> I have my practical exam tomorrow morning.
May 24 20:19:58 <ZeekHuge> jkridner: ??
May 24 20:20:13 <ZeekHuge> what forms do it need to complete ?
May 24 20:20:22 <m_w> send an email and go to sleep.
May 24 20:20:41 <ZeekHuge> okay.
May 24 20:26:42 <Wormo> yes I was hoping somebody contacted you already from shipper, if not ask jkridner
May 24 20:26:49 <pmezydlo> m_w: my progress report is on mailing list
May 24 20:28:22 <m_w> okay I will look it over
May 24 20:32:29 <nerdboy> jkridner: added this to spreadsheet:  http://www.mouser.com/ProductDetail/Analog-Devices/AD9201ARSZ/?qs=%2FtpEQrCGXCzwVkiwZM9tlA%3D%3D
May 24 20:32:40 <nerdboy> add to your cart and you're done
May 24 20:44:44 <ZeekHuge> Kernel source is compiling !
May 24 20:44:50 <ZeekHuge> Thanks to m_w and Wormo
May 24 20:44:57 <Wormo> yay thanks to m_w
May 24 20:45:27 <ZeekHuge> there was a warning somewhere .. primptable_lazy defined but not used kind of.
May 24 20:45:27 <Wormo> quick status email to group?
May 24 20:45:39 <ZeekHuge> Morning ? please ..
