**** BEGIN LOGGING AT Wed Aug 23 03:00:01 2017
Aug 23 15:58:50 <m_w> last meeting today, hope everyone is documenting at this point
Aug 23 16:00:05 <ee> Good evening
Aug 23 16:00:20 <thetransformerr[> hii
Aug 23 16:00:27 <ravikp7> Hi :)
Aug 23 16:00:33 <maciejjo> hi
Aug 23 16:01:08 <indu> Hello
Aug 23 16:01:58 <tlwoerner> o/
Aug 23 16:02:04 <m_w> _av500_: y'all ready for this?
Aug 23 16:02:07 <nerdboy> moin
Aug 23 16:02:23 <_av500_> hi guys
Aug 23 16:02:28 <_av500_> I have 30 minutes today
Aug 23 16:02:35 <_av500_> so I have to leave in 30
Aug 23 16:02:36 <jkridner> howdy _av500_!
Aug 23 16:02:41 <_av500_> hi jkridner
Aug 23 16:02:45 <m_w> lighting talks go!
Aug 23 16:02:48 <_av500_> 1) Welcome everybody
Aug 23 16:02:51 <_av500_> roll call
Aug 23 16:02:54 <thetransformerr[> hey
Aug 23 16:02:59 <ee> hello :)
Aug 23 16:03:02 <indu> here
Aug 23 16:03:04 <maciejjo> here
Aug 23 16:03:06 <jkridner> _av500_: have final videos been discussed?
Aug 23 16:03:13 <ee> tlwoerner: please PM me, not able to do it myself for some reason
Aug 23 16:03:15 <ravikp7> present
Aug 23 16:03:21 <_av500_> jkridner: oops no
Aug 23 16:03:28 <_av500_> jkridner: shame on me, I forgot
Aug 23 16:03:52 <_av500_> pmezydlo: ping
Aug 23 16:03:58 <_av500_> I count 5 so far
Aug 23 16:04:05 <pmezydlo> hi, i'm here
Aug 23 16:04:30 <ee> brb something weird is happening, relogging
Aug 23 16:04:48 <rma> Hi all!
Aug 23 16:05:13 <_av500_> hi rma
Aug 23 16:05:17 <_av500_> so. everybody here
Aug 23 16:05:18 * nerdboy did send please-document-your-crap email...
Aug 23 16:05:20 <_av500_> 2) reports
Aug 23 16:05:26 <_av500_> I count 6
Aug 23 16:05:30 <_av500_> final week
Aug 23 16:06:23 <_av500_> anybody stuck?
Aug 23 16:06:29 <_av500_> any last issues?
Aug 23 16:06:34 <pmezydlo> no it's fine
Aug 23 16:06:40 <pmezydlo> a lot of work
Aug 23 16:06:44 <ravikp7> all good here
Aug 23 16:06:52 <maciejjo> i'm ok
Aug 23 16:07:00 <thetransformerr[> ok
Aug 23 16:07:11 <jkridner> ravikp7: like the updates to the README.md files, but still would love to see travis-ci automated downloadable builes.
Aug 23 16:07:13 <jkridner> builds even.
Aug 23 16:07:29 <_av500_> ok great
Aug 23 16:07:49 <ravikp7> jkridner: working on it
Aug 23 16:07:51 <jkridner> ravikp7: also, loading up the issues lists with roadmap items we discussed to the best of your understanding, knowing that someone else would need to come around to implement/fix.
Aug 23 16:08:03 <av500> jkridner: ravikp7: pls do that after the meeting
Aug 23 16:08:04 <ee> lots of work here too, but progress is being made
Aug 23 16:08:16 <av500> ee: its final week
Aug 23 16:08:23 <av500> so make sure you leave it in a usable state
Aug 23 16:08:26 <ravikp7> ok, sure
Aug 23 16:08:29 <av500> no new features at this point
Aug 23 16:08:34 <av500> that goes for everybody
Aug 23 16:08:44 <av500> make sure you have everything pushed and documented
Aug 23 16:08:54 <av500> document lose ends rather than trying to fix them now
Aug 23 16:09:02 <nerdboy> you mean we can't steal time from test to throw in extra stuff?
Aug 23 16:09:11 <av500> time is over soon
Aug 23 16:09:37 <av500> so as I said, wrap it up
Aug 23 16:09:44 <nerdboy> but that's the way "agile" managers do it...
Aug 23 16:09:49 <av500> make sure with your mentors that they can reproduce what you did
Aug 23 16:10:05 <av500> so we have the project in a state that somebody can  continue
Aug 23 16:10:10 <av500> be it you or somebody else
Aug 23 16:10:23 <av500> any questions about that?
Aug 23 16:11:00 <ee> nope, all sounds good
Aug 23 16:11:26 <ravikp7> +1
Aug 23 16:11:30 <pmezydlo> +2
Aug 23 16:11:36 <thetransformerr[> yeah I m good too
Aug 23 16:11:39 <maciejjo> +3
Aug 23 16:11:55 <av500> indu: ?
Aug 23 16:12:02 <indu> I am good
Aug 23 16:13:03 <av500> good
Aug 23 16:13:21 <av500> then we are all set for the final days
Aug 23 16:13:40 <av500> remember the dates you have to submit final evals
Aug 23 16:13:53 <thetransformerr[> before 29
Aug 23 16:13:54 <av500> students by Aug 29th
Aug 23 16:13:55 <av500> yes
Aug 23 16:14:00 <av500> do it over the weekend
Aug 23 16:14:06 <nerdboy> we get "friendly" reminders for that...
Aug 23 16:14:41 <av500> yes
Aug 23 16:14:42 <ds2> the final days....
Aug 23 16:14:47 <thetransformerr[> hey I jus wanted to ask does after gsoc all mentors still hang arnd here
Aug 23 16:14:47 <av500> mentors have a week more
Aug 23 16:14:53 <av500> thetransformerr[: some do
Aug 23 16:14:54 <thetransformerr[> aur some other forum
Aug 23 16:14:56 <thetransformerr[> ?
Aug 23 16:14:59 <av500> here or in #beagle
Aug 23 16:15:07 <av500> or email
Aug 23 16:15:20 <ds2> yep
Aug 23 16:15:31 <nerdboy> mostly they are here, more or less...
Aug 23 16:15:42 <nerdboy> s/they/we/
Aug 23 16:16:51 <ds2> is anyone really 'here'?
Aug 23 16:17:13 <nerdboy> where is "here"?
Aug 23 16:17:19 <av500> ok, so I have to leave this meeting soon
Aug 23 16:17:20 <thetransformerr[> and does anybody feeling nostalgic abt our last meeting :)
Aug 23 16:17:38 <nerdboy> av500: you have 13 more minutes
Aug 23 16:17:43 <av500> well yes
Aug 23 16:17:45 <av500> but....
Aug 23 16:18:09 <jkridner> av500: when can we start our reviews?
Aug 23 16:18:10 <nerdboy> no sneaking out early
Aug 23 16:18:36 <av500> jkridner: 29th
Aug 23 16:18:38 <av500> until 5th
Aug 23 16:18:45 <av500> this time I will send hourly emails
Aug 23 16:19:17 <ee> lmao
Aug 23 16:19:33 <ee> oops, meant lol
Aug 23 16:19:37 <ravikp7> For final work submission to google, a medium blog post would be good, right?
Aug 23 16:19:39 <thetransformerr[> really ee:
Aug 23 16:19:44 * nerdboy needs to complete testing/eval by next week
Aug 23 16:19:46 <rma> great
Aug 23 16:21:46 <ravikp7> Final videos deadline?
Aug 23 16:22:09 <ee> ^
Aug 23 16:22:10 <av500> yes, we forgot about the final videos
Aug 23 16:22:15 <av500> I'm sorry about that
Aug 23 16:22:21 <av500> the deadline would be next week
Aug 23 16:22:22 <nerdboy> 8 minutes
Aug 23 16:22:31 <av500> nerdboy: impatient?
Aug 23 16:22:41 <nerdboy> nope
Aug 23 16:22:51 <av500> so around next wednesday
Aug 23 16:23:10 <av500> jkridner: nerdboy: please take over from here
Aug 23 16:23:34 <av500> I really need to go now :)
Aug 23 16:23:51 <nerdboy> 30 minutes my ass...
Aug 23 16:23:51 <av500> good luck everybody for the final week!
Aug 23 16:23:58 <av500> nerdboy: :)
Aug 23 16:24:03 <ee> thanks, see you later av500 :)
Aug 23 16:24:05 <av500> here is a ~
Aug 23 16:24:12 <av500> thanks
Aug 23 16:24:20 <jkridner> av500: what else needs to be on the agenda today?
Aug 23 16:24:26 * jkridner waves to av500
Aug 23 16:24:35 <av500> jkridner: nothing much
Aug 23 16:24:36 <ravikp7> av500: thanks, bye ;)
Aug 23 16:24:40 <jkridner> nerdboy: has a final videos deadline been discussed?
Aug 23 16:24:45 <av500> jkridner: videos
Aug 23 16:24:52 <ee> "around next wednesday"
Aug 23 16:24:55 <nerdboy> middle of next week
Aug 23 16:26:22 * nerdboy poking at toolchain build for some Ada goodness...
Aug 23 16:26:27 <ee> tlwoerner: are you seeing any of my messages (from this acct or ee69)?
Aug 23 16:27:10 <nerdboy> ee: as long as you auth with freenode you should be ok
Aug 23 16:27:24 <ee> tlwoerner: yeah I can see your messages, I just can't send any to you
Aug 23 16:27:33 <ee> yeah dunno what's up, unauthed today for some reason
Aug 23 16:27:45 <nerdboy> well, re-auth
Aug 23 16:27:58 <nerdboy> i have to do that every time my proxy hiccups
Aug 23 16:28:23 <jkridner> everybody seen examples and understand the goal?
Aug 23 16:28:28 <tlwoerner> ee: or send me an email
Aug 23 16:28:49 <nerdboy> did you /msg nickserv identify foo again?
Aug 23 16:29:24 <nerdboy> jkridner: you mean video examples?
Aug 23 16:29:37 <ravikp7> examples? havn't seen one
Aug 23 16:30:21 <nerdboy> i think if you cover the main functionality in a demo-y way that should work
Aug 23 16:30:28 <ee> tlwoerner: dunno what's going on, I'll email you tonight
Aug 23 16:30:45 <tlwoerner> ee: np
Aug 23 16:30:47 <nerdboy> make some bullets of the accomplishments?
Aug 23 16:31:32 <jkridner> nerdboy: yes
Aug 23 16:31:40 <nerdboy> describe things not done, what should be done next?
Aug 23 16:31:43 <jkridner> ravikp7: just video examples.
Aug 23 16:31:49 <ravikp7> got it
Aug 23 16:33:19 <nerdboy> over-voltage warnings "don't blow this up"...
Aug 23 16:40:23 <jkridner> nerdboy: anything left for the "official" meeting? if there aren't questions about the final video, then I think we can go back to discussing individual project issues.
Aug 23 16:40:50 * jkridner needs to check if any X15s shipped.
Aug 23 16:43:06 <indu> sorry I forgot to mention this, just last week I got x15. This is late to include it in GSOC
Aug 23 16:43:49 <indu> I will include it in the continuation of the project
Aug 23 16:45:27 <nerdboy> when do i get one?
Aug 23 16:46:01 <nerdboy> jkridner: and i think we're done unless someone still has a question...
Aug 23 16:46:28 <jkridner> indu: super you got one!
Aug 23 16:46:34 <nerdboy> Abhishek_: you're late
Aug 23 16:46:51 <nerdboy> you just missed the beagle chorus line
Aug 23 16:47:02 <Abhishek_> ouch
Aug 23 16:47:14 <nerdboy> good thing too, i think my eyes are burned out...
Aug 23 16:47:43 <rma> bye guys
Aug 23 16:48:03 <thetransformerr[> bye
Aug 23 16:50:50 <Abhishek_> jkridner: Routing for BeagleLogic standalone is coming up but slowly.
Aug 23 16:51:11 <jkridner> Abhishek_: did you try m_w's updated part placement?
Aug 23 16:51:54 <Abhishek_> yep, giving it a look. I'm not sure routing's doable in 4 layers.
Aug 23 16:52:58 <Abhishek_> CircuitHub can do 6 layers too, but that would drive up the assembly cost for the prototypes.
Aug 23 17:00:00 <m_w> Abhishek_: yeah I didn't look too closely at the routing
Aug 23 17:01:05 <m_w> there might be some good take aways from the placement
Aug 23 17:01:22 <Abhishek_> Yeah sure, that's what I hope to incorporate into the layout
Aug 23 17:01:50 <Abhishek_> For example the ESD protection diodes on the opposite side of the logic level shifter 74245
Aug 23 17:02:03 <m_w> I think trick is maybe reordering the headers a bit too
Aug 23 17:02:23 <m_w> to untangle the nets
Aug 23 17:02:50 <m_w> the ethernet PHY would probably be easier to route on the bottom side
Aug 23 17:03:04 <Abhishek_> Yep, that's what I have done finally.
Aug 23 17:03:20 <Abhishek_> (that's what is currently routed)
Aug 23 17:04:20 <m_w> you want to try even smaller than 65mmx75mm?
Aug 23 17:06:05 <Abhishek_> 65x75 is good enough, if I want to go even smaller I'd have to use more BGA parts
Aug 23 17:06:25 <Abhishek_> like for the level shifter
Aug 23 17:07:18 <ds2> ewww eth
Aug 23 17:07:26 <m_w> there are still some tricks you can use
Aug 23 17:07:32 <ds2> doing gige too?
Aug 23 17:07:40 <m_w> yup gig eth
Aug 23 17:07:54 <ds2> how many layers?
Aug 23 17:08:10 <m_w> he is shooting for 4 layers
Aug 23 17:08:45 <ds2> oh my... that is a pita as gigeneeds imped matchimg
Aug 23 17:10:50 <Abhishek_> on the data lines or the ethernet signal lines?
Aug 23 17:11:04 <Abhishek_> (data lines - RGMII)
Aug 23 17:11:17 <ds2> rgmii... they r ddr
Aug 23 17:11:49 <ds2> that is.why my mod was not for gige
Aug 23 17:13:05 <Abhishek_> gigabit ethernet is the reason I'm doing a standalone board, if it doesn't work, it's a lot of wasted effort.
Aug 23 17:13:54 <ds2> read the ti docs... i have been involved w/one... focs essential
Aug 23 17:20:28 <m_w> Abhishek_: I would reach out to the PCB manufacturer to see if they can provide controlled impedence
Aug 23 17:23:40 <Abhishek_> will do
Aug 23 17:26:20 <nerdboy> nope, same diff
Aug 23 17:26:27 <nerdboy> oops...
Aug 23 17:35:45 <ds2> Abhishek_: what fab are you using?
Aug 23 17:36:01 <ds2> most cheap stackups really suck for impedence controlled stuff
Aug 23 17:47:42 <m_w> 4 layers with controlled impedence can cost just as much as 6 layers
Aug 23 17:48:06 <m_w> without the benefits of having the extra 2 layers
Aug 23 17:48:38 <ds2> except impedence control can force fat traces to require 6L
Aug 23 17:49:55 <m_w> yeah it depends on the thickness and materials used in the PCB
Aug 23 17:52:26 <m_w> the PCB house should be able to give you the dielectric constant and detailed stack up
Aug 23 17:53:03 <ds2> isn't USB used in this board too?
Aug 23 17:53:07 <m_w> they can even give you the trace widths require on each layer
Aug 23 17:53:14 <m_w> yes
Aug 23 17:54:06 <ds2> that definitely needs impedence control... IIRC - the original pocket bone w/o that didn't work
Aug 23 17:54:20 <m_w> the outside layers are harder to impedence match than internal layers
Aug 23 17:54:35 <ee> jkridner: got an x15 too
Aug 23 17:54:42 <ds2> how so?
Aug 23 17:54:52 <ee> jkridner: got more customs too, could I please get reimbursed for those?
Aug 23 17:55:12 <m_w> the original pocketbone was routed incorrectly and the crystals were swapped
Aug 23 17:55:27 <ds2> oh DOH
Aug 23 17:56:05 <m_w> one of the USB pair lines was coupled to the ID line instead of the other USB differential line
Aug 23 17:57:02 <m_w> I used 4 layers for the kicad version and it seems to work okay
Aug 23 17:57:32 <ds2> did you run a BERT on the USB port or the eye diagram thingie?
Aug 23 17:57:47 <ds2> and if so, any recommendations for cheap way of doing it? :D
Aug 23 17:57:53 <m_w> don't have the equipment
Aug 23 17:58:20 <m_w> too poor to afford the fancy scope and probes
Aug 23 17:58:49 <ds2> probes can be made
Aug 23 18:01:04 <m_w> yeah
Aug 23 18:18:06 <pdp7> Abhishek_ m_w: OSH Park will do any boards you need for free. Just email me drew@oshpark.com.  our 4 layer specs: http://docs.oshpark.com/services/four-layer/
Aug 23 18:18:21 <pdp7> PCB Substrate dielectric constant of 3.66 at 1GHz
Aug 23 18:18:45 <pdp7> Isola FR408 datasheet http://docs.oshpark.com/resources/FR408-High-Performance-Laminate-and-Prepreg-Data-Sheet.pdf
Aug 23 18:19:56 <pdp7> We created the stackup based on feedback from an RF designer. It should make it easy to have 50 Ohm impedance: https://blog.oshpark.com/2016/03/28/michael-ossmanns-rf-design-rules/
Aug 23 18:21:11 <ds2> pdp7: easy, yes. tiny, no.
Aug 23 18:37:49 <pdp7> ds2: in terms of board area?
Aug 23 18:38:07 <ds2> yes, traces are still pretty fat
Aug 23 18:38:31 <m_w> Abhishek_: how is the board powered? USB only?
Aug 23 18:41:58 <m_w> the gigabit ethernet can draw up to 221mA at 1.2V on top on the ~100mA at 3.3V
Aug 23 18:43:10 <m_w> that does not leave much for the main processor on a 500mA limited USB connection
Aug 23 18:43:50 <m_w> especially considering you are using an LDO
Aug 23 18:44:37 <m_w> not to be a party pooper or anything
Aug 23 18:47:26 <m_w> to be safe you can add a barrel jack
Aug 23 18:49:24 <m_w> I should be getting the parts to build the lofive boards today
Aug 23 18:51:11 <m_w> also if you want a bit more wiggle room you could go with the original beagleboard formfactor (3"x3")
Aug 23 18:53:18 <m_w> or 75mmx75mm if you like metric
Aug 23 18:57:25 <ds2> m_w: what about the PHY?
Aug 23 18:58:06 <m_w> the gigabit phy is what I am talking about
Aug 23 18:58:52 <ds2> oh
Aug 23 18:59:11 <ds2> power management!
Aug 23 18:59:21 <ds2> run the A8 @ 100KHz ;)
Aug 23 18:59:35 <m_w> ha
Aug 23 18:59:56 <m_w> I bet that would defeat the purpose a bit
Aug 23 19:00:12 <ds2> or prehaps a super cap and duty cycle limit hte uptime of the GigE
Aug 23 19:00:50 <m_w> that would be tricky and be expensive on the board size
Aug 23 19:01:15 <ds2> board volume...
Aug 23 19:01:37 <m_w> I would change the 1.2V rail to a switcher
Aug 23 19:05:14 <m_w> and still add the barrel jack
Aug 23 19:06:02 <ds2> put in a battery
Aug 23 19:06:20 <m_w> the battery could do it
Aug 23 19:06:53 <ds2> or fix the code for dedicated charger detect...the USB PHY can do it
Aug 23 19:07:05 <ds2> have that adjust the PMIC
Aug 23 19:12:14 <m_w> I would switch to a JST-PH connector if a lipo battery is going to be a integral part of the design
Aug 23 19:13:14 <m_w> instead of the generic 4 pin header
Aug 23 19:15:28 <ds2> m_w: why?
Aug 23 19:15:53 <ds2> I have seen 2 pin headers with a mix of polarities... seems like an invitation for disaster
Aug 23 19:17:11 <m_w> JST-PH connector is a polarized locking connector isnt it?
Aug 23 19:17:43 <ds2> yep
Aug 23 19:17:48 <m_w> and lots of batteries are made to plug right in
Aug 23 19:18:03 <ds2> battery suppliers don't seem to care.. I was soldering bare wires so it wasn't a big deal
Aug 23 19:18:30 <m_w> those bastards
Aug 23 19:18:41 <m_w> are the wires at least color coded?
Aug 23 19:18:44 <ds2> took a double take to confirm red and black are swapped
Aug 23 19:18:59 <ds2> yes... but I verified that with a meter :D
Aug 23 19:20:22 <m_w> I bet at the ones from adafruit are wired the same way ;)
Aug 23 19:21:18 <m_w> https://www.adafruit.com/product/1131?q=lipo&gclid=Cj0KCQjwz_TMBRD0ARIsADfk7hSRIvi-M-K99n7EOlrtA-Ula_Q16-g1RHAgHUfxrbtgj04F-a-pUbMaAuuMEALw_wcB
Aug 23 19:21:53 <ds2> but the ebay ones....
Aug 23 19:22:27 <m_w> yeah I don't usually trust most things on ebay
Aug 23 19:23:31 <ds2> yes but if you need the battery in a given geometry...
Aug 23 19:23:50 <m_w> this is true, really depends on the app
Aug 23 19:24:06 <m_w> and not everyone can afford a custom battery
Aug 23 19:24:21 <ds2> yep
Aug 23 19:26:01 <m_w> ds2: have you reviewed the design? it is on github
Aug 23 19:26:09 <ds2> what's the URL?
Aug 23 19:26:11 <m_w> more eyes the better
Aug 23 19:26:25 <m_w> https://github.com/abhishek-kakkar/beaglelogic-standalone
Aug 23 19:27:01 <ds2> blah... no PDF == no review
Aug 23 19:27:12 <m_w> hold on a second
Aug 23 19:27:14 <ds2> no going down the cesspool of chasing ECAD SW versions
Aug 23 19:27:31 <ds2> (sorry, in the center of a MCAD SW version battle right now, not starting another front)
Aug 23 19:29:47 <m_w> https://drive.google.com/open?id=0B71fXOiSxXI3LW9OQ2taSm5JQUk
Aug 23 19:30:21 <ds2> whoa 1 page
Aug 23 19:30:31 <m_w> yup
Aug 23 19:30:42 <m_w> easier to review
Aug 23 19:31:12 <m_w> I think beagleboard.org should do a summer of hardware next year
Aug 23 19:31:17 <m_w> :)
Aug 23 19:32:27 <m_w> BSoH
Aug 23 19:32:35 <ds2> not really
Aug 23 19:32:45 <ds2> too much zooming in and out
Aug 23 19:33:27 <m_w> BSoD X-/
Aug 23 19:34:52 <ds2> hmmm not battery friendly design
Aug 23 19:35:55 <ds2> SPI flash!
Aug 23 19:35:57 <ds2> ?
Aug 23 19:36:30 <m_w> for the bootloader
Aug 23 19:36:39 <ds2> why? there is eMMC there
Aug 23 19:37:07 <m_w> you can't always boot out of eMMC on some of the channels
Aug 23 19:37:28 <m_w> I found this out the hard way on the SOM-3354
Aug 23 19:37:50 <ds2> hmmm?
Aug 23 19:37:53 <ds2> what's the issue?
Aug 23 19:37:58 <m_w> you can boot out of the eMMC on the secondary channel but only if it is the older spec
Aug 23 19:38:11 <m_w> < 2GB usually
Aug 23 19:38:12 <ds2> also, where are the SYSBOOT stuff?
Aug 23 19:38:25 <ds2> oh that icky detail...
Aug 23 19:38:54 <m_w> yeah it was a major bummer when I found it
Aug 23 19:39:15 <ds2> well... find a supplier that will sell the right stuff :D
Aug 23 19:39:16 <m_w> the SPI flash can get you to U-Boot and then the eMMC can be used from there
Aug 23 19:39:41 <ds2> waste of room, IMO
Aug 23 19:39:51 <m_w> we found one supplier that had a hacked 4GB eMMC but I think it went EOL
Aug 23 19:40:17 <ds2> I choose not to use eMMC and just boot from a uSD card
Aug 23 19:41:06 <m_w> well it is an option
Aug 23 19:41:36 <ds2> there is already concern about board space...
Aug 23 19:42:13 <m_w> up to Abhishek_
Aug 23 19:42:35 <ds2> easiest way to solve board space problems is to eliminate parts
Aug 23 19:42:47 <ds2> (and let the SW guys deal with it...)
Aug 23 19:42:59 <m_w> ha
Aug 23 19:43:47 <m_w> well the boot options are clearly marked, they are pulled by rnets smack in the middle
Aug 23 19:44:16 <m_w> aren't clearly marked :)
Aug 23 19:45:42 <m_w> he wanted the 8 bit eMMC but it didn't line up correctly for the boot rom so I think it is out for booting
Aug 23 19:45:58 <m_w> the SD card could be used
Aug 23 19:46:01 <m_w> I think
Aug 23 19:50:09 <ds2> still don't see the boot config *shrug*
Aug 23 19:52:10 <m_w> under the text "Logic Inputs"
Aug 23 19:52:18 <m_w> RN1-RN4
Aug 23 19:52:38 <ds2> ah...
Aug 23 19:52:47 <ds2> has nothing to do with logic inputs though :/
Aug 23 19:53:11 <ds2> I see he choose not to label them as SYS_BOOT either.
Aug 23 19:53:16 <m_w> well the PRU input overlap with the LCD/SYSBOOT lines
Aug 23 19:53:32 <ds2> yes but a note there would help....esp if someone is doing SW bring up
Aug 23 19:53:59 <m_w> yeah a table would be nice
Aug 23 19:54:16 <ds2> I'd be happy to see SYSBOOT[1... labeled on the pins
Aug 23 19:54:38 <ds2> my docs say it... the ORCAD versions say it... :D
Aug 23 19:54:48 <ds2> conclusion... must be a limitation of KiCAD ;)
Aug 23 19:55:51 <m_w> blame the software
Aug 23 20:19:29 <nerdboy> yeah, i might dump flash/emmc for sdcard too
Aug 23 20:19:37 <nerdboy> make it simple
Aug 23 20:20:00 <nerdboy> you might look at the drone batteries
Aug 23 20:20:19 <nerdboy> they seem to have some sort of "standard" sizes/wiring
Aug 23 20:20:46 <nerdboy> not that i have looked at/tested very many
Aug 23 20:21:08 <nerdboy> only the hubsan and one other one
Aug 23 20:21:10 <ds2> be careful with charging requirements
Aug 23 20:21:39 <nerdboy> i mean the smallish 3.7 lipos
Aug 23 20:21:50 <ds2> yes, esp. small ones
Aug 23 20:21:52 <nerdboy> also there is one for the pocketchip
Aug 23 20:22:07 <ds2> the default charge rate may be too high for the smaller ones
Aug 23 20:22:09 <nerdboy> nice size, runs it for quite a while
Aug 23 20:22:36 <nerdboy> pocketchip charges/runs off usb fine
Aug 23 20:22:59 <nerdboy> meaning desktop usb port
Aug 23 20:23:05 <ds2> is it USB compliant?
Aug 23 20:23:25 <nerdboy> i want to say "yes" but i don't know for sure
Aug 23 20:23:44 <nerdboy> their hardware should be documented/public
Aug 23 20:23:44 <ds2> I suspect not given the WiFi and LCD backlight
Aug 23 20:24:23 <nerdboy> it's a fairly low-power allwinner
Aug 23 20:24:44 <ds2> WiFi and LCD backlights are outside of the A10
Aug 23 21:09:53 <ravikp7> jkridner: the travis-ci build release is working now, just pushed an alpha release of app
Aug 23 21:10:06 <ravikp7> jkridner: the linux packages are available to download now, the os x dmg will be available as soon as the build starts...
Aug 23 21:17:24 <ravikp7> jkridner: the release is in draft, will publish once the os x build gets completed on the ci server
Aug 23 21:43:18 <ravikp7> seems there's a huge backlog for mac builds..
Aug 23 21:46:48 <ravikp7> jkridner: just published with the local dmg build, will have a look at the ci build logs once it's completed for os x
Aug 24 02:36:27 <Abhishek_> m_w: Might consider swapping out the Ethernet PHY for an AR8035 instead of KSZ9031; the AR part has a switcher, no LDO required
Aug 24 02:38:24 <Abhishek_> m_w: I have a test point for 5V input, might consider adding a barrel jack
