May 26 05:59:49 <Abhishek_> back to my nick :P
May 26 06:03:23 <Abhishek_> ds2 and m_w: What's the status on ZeekHuge and clocking the ADC yet?
May 26 06:06:54 <m_w> Abhishek_: I think we decided to add a driver and use the coax input
May 26 06:07:22 <m_w> so we don't have to wiremod the board
May 26 06:07:36 <m_w> bed time for me
May 26 06:09:19 <Abhishek_> Okay, which driver IC will be used?
May 26 06:09:31 <ds2> Abhishek_: I don't think there is a clear path. no part was identified
May 26 06:10:45 <ds2> Abhishek_: we talked about a few options such as a simple emitter follower
May 26 06:11:12 <Abhishek_> If I were to do it, I would mod the board, remove the termination and connect to the PRU output directly
May 26 06:11:26 <Abhishek_> or through the on board TTL buffer
May 26 06:11:49 <ds2> concern for that would be the wires
May 26 06:12:02 <ds2> can the 335x drive things properly
May 26 06:12:51 <Abhishek_> but then I don't know ZeekHuge's soldering skills I do not endorse modding the board
May 26 06:13:03 <Abhishek_> shipping replacements will kill time
May 26 06:13:42 <Abhishek_> The LCD cape you saw at the Maker faire uses a ~100MHz pixclk that's driven by the LCD pins
May 26 06:13:49 <Abhishek_> ds2: ^
May 26 06:15:38 <Abhishek_> The resistor termination provided on the LCD pins for the HDMI framer can handle 100MHz signals well
May 26 06:17:14 <Abhishek_> The emitter follower idea sounds feasible to me - hopefully ZeekHuge can get access to a scope at university
May 26 06:17:19 <ds2> Abhishek_: yes, that's why I said, the PRU on the LCD pins may help... flip side is those lines are T'ed
May 26 06:17:39 <ds2> the LCD may also be more tolerant then the ADC
May 26 06:17:44 <Abhishek_> there's RC termination IIRC
May 26 06:17:55 <ds2> IIRC - only R is populated
May 26 06:18:06 <ds2> 22 ohm source side termination
May 26 06:18:20 <Abhishek_> ZeekHuge: check TRM of the BeagleBone Black when you go through this
May 26 06:19:14 <ds2> if equipment is available, I'd say the safest is an emitter follower driving a short length of coax so the ADC board is unmod'ed
May 26 06:19:41 <ds2> that way the signal can be verified on a scope with a proper terminator...this does assume equipment is available
May 26 06:58:54 <kiran4399> Abhishek_: there?
May 26 06:59:05 <Abhishek_> only for a short while, go ahead
May 26 06:59:34 <kiran4399> for the last week.. I was searching a lot about pru remoteproc  and stuff..
May 26 06:59:39 <kiran4399> so for 4.4
May 26 06:59:48 <kiran4399> should I use shubhangi's pru_framework?
May 26 06:59:52 <kiran4399> with some modifications?
May 26 07:00:06 <kiran4399> Abhishek_: ^^
May 26 07:00:12 <Abhishek_> if it compiles use it, if not try starting from scratch
May 26 07:00:53 <Abhishek_> coding has already begun so don't remain stuck for long
May 26 07:01:01 <kiran4399> Abhishek_: do'nt you want me to make some modifications?
May 26 07:01:11 <kiran4399> to pru-framework?
May 26 07:01:18 <kiran4399> for 4.4?
May 26 07:01:37 <Abhishek_> I don't expect that it's gonna work in 4.4, there's a new driver in rpmsg actually
May 26 07:01:45 <Abhishek_> look in drivers/rpmsg
May 26 07:02:07 <Abhishek_> in the 4.4 tree
May 26 07:02:20 <kiran4399> Abhishek_: OK..
May 26 07:06:22 <Abhishek_> ZeekHuge: read about how do you actually read data from the ADC (go through the datasheets)
May 26 07:06:28 <kiran4399> kiran4399: OK.. I see it.. so if I use rpmsg.. then that driver will give me some kind Remote procedure call API to userspace..
May 26 07:07:55 <kiran4399> Abhishek_: is rpmsg an alternative for remoteproc?
May 26 07:08:01 <kiran4399> for 4.4
May 26 07:08:03 <kiran4399> ?
May 26 07:12:38 <Abhishek_> It's a new thing that's been introduced in 4.4 by people at TI
May 26 07:12:54 <Abhishek_> Jason Reeder is the guy who maintains it
May 26 07:15:45 <kiran4399> Abhishek_: Cool!!
May 26 10:01:03 <kiran4399> Hi!! does anybody know how to transfer a kernel uimage to beaglebone black which is using ubuntu 14.04?
May 26 16:52:53 <kiran4399> Does anybody know what is the barometer on strawson board?

May 26 17:03:25 <pmezydlo1> m_w: hi, how are you? :)
May 26 17:07:14 <m_w> pmezydlo1: good
May 26 17:07:24 <m_w> fun morning so far
May 26 17:07:45 <pmezydlo1> great, me too
May 26 17:07:47 <m_w> just sat in on the openhours for 96boards online
May 26 17:08:36 <pmezydlo1> 96boards -> google
May 26 17:08:50 <m_w> linaro
May 26 17:09:00 <pmezydlo1> http://www.96boards.org/ ?
May 26 17:09:28 <m_w> https://www.youtube.com/watch?v=k7QR_KlXMRc&index=3&list=PL-NF6S9MM_W1QBjUc2B5Pg502bz7qslxk
May 26 17:09:56 <m_w> two weeks in a row
May 26 17:14:32 <pmezydlo1> seems interesting, What are you working on?
May 26 17:14:56 <m_w> robomezzi
May 26 17:15:17 <m_w> https://github.com/mwelling/96boards-robomezzi
May 26 19:36:41 <nerdboy> you definitely want the rcn kernel packages or else build from rcn patch repo
May 26 19:37:21 <nerdboy> 4.1 ti-staging (in meta-ti) is broken wrt thumb
May 26 23:33:50 <ZeekHuge> anybody has the link to pdf describing various pinmux settings of GPIO ?
May 26 23:34:21 <ZeekHuge> I had a very good one, but i am unable to find it now.
May 26 23:34:24 <ZeekHuge> ?
May 26 23:35:30 <ZeekHuge> I found em !
May 26 23:48:43 <ZeekHuge> I would like to include these two pdfs ( https://github.com/derekmolloy/boneDeviceTree/tree/master/docs ) in my BeagleScope repo's docs . can i ? also, please give me a general set of rules/points i should keep in mind before adding someone else's work in my project.
May 27 00:11:25 <alexhiam> kiran4399: you around?
May 27 00:31:54 <ZeekHuge> hey alexhiam can you help with that ?
May 27 00:31:57 <ZeekHuge> ^^
May 27 00:32:45 <ZeekHuge> i have never got into issues like taking care of License or something like this.
May 27 00:33:14 <ZeekHuge> so, should I mail each and everyone before using his material on github ?
May 27 00:33:21 <alexhiam> ZeekHuge: look at the README
May 27 00:33:25 <alexhiam> "Redistribution and use in source and binary forms, with or without modification, are permitted provided that source code redistributions retain this notice."
May 27 00:34:29 <alexhiam> ZeekHuge: you certainly could, just stick a text file in there with the copyright notice and that
May 27 00:34:33 <ZeekHuge> ahh .. yep.
May 27 00:34:58 <alexhiam> though, it might be better to just link to those pdfs, as then you wouldn't have to worry about them getting out of date if the originals get updated
May 27 00:35:22 <ZeekHuge> yeah okay.
May 27 00:47:34 <ZeekHuge> ds2: https://github.com/ZeekHuge/BeagleScope/blob/master/docs/BBB-ADC.pdf
May 27 00:47:47 <ZeekHuge> is this how the schematic should look ?
