**** BEGIN LOGGING AT Wed Jun 17 02:59:59 2015
Jun 17 03:21:11 <agmlego> I have many suggestions, but not for those who stick around that short.
Jun 17 07:02:46 <twid> does BBB supports kernel version 4.1
Jun 17 07:03:21 <araru> hekko
Jun 17 07:03:26 <araru> hello
Jun 17 07:03:28 <araru> need help
Jun 17 07:03:34 <tbr> twid: yes, of course
Jun 17 07:04:04 <twid> tbr: thanks
Jun 17 07:04:18 <araru> I want to connect my BBB to the internet directly through the Internet port ( via DHCP ) and then look into it via USB from a linux machine through putty
Jun 17 07:04:25 <araru> how do it do it  ?.
Jun 17 07:05:00 <tbr> araru: that will depend on which linux distribution you are running on the device
Jun 17 07:05:14 <araru> it is a out of box one
Jun 17 07:05:25 <araru> so the flash has factory image
Jun 17 07:05:30 <araru> by BBB is a REvB
Jun 17 07:05:52 <tbr> then the first order of business is to reflash it with an up to date debian image
Jun 17 07:05:56 <araru> I want to do this so that I can get updates directly onto the board
Jun 17 07:06:08 <tbr> as it's a rev B you'll need to make sure to get a 2GB image
Jun 17 07:07:38 <araru> uname -a gets me Linux beaglebone 3.8.13, armv71 GNU/Linux
Jun 17 07:07:47 <araru> ok this @GB one is a new one ?.
Jun 17 07:07:54 <araru> 2GB one is a new one ?.
Jun 17 07:07:55 <tbr> http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBB_.28All_Revs.29_eMMC_Flashers
Jun 17 07:08:25 <tbr> board revision B has only 2GB eMMC, so you can't flash a 4GB rev C image to it, obviously.
Jun 17 07:09:23 <araru> Ok Ok
Jun 17 07:09:43 <araru> and then ? after I boot it up with the new image what do it do ?.
Jun 17 07:09:58 <araru> I think the inbuild IP address would stay the same
Jun 17 07:10:05 <tbr> it will just work
Jun 17 07:10:34 <araru> ho the dhcp would be enabled and it can fetch its adress over the IP cable directly?.
Jun 17 07:11:22 <woglinde> if you edit the right files
Jun 17 07:12:22 <araru> right files ?. the netwrok ones ?.
Jun 17 07:12:25 <tbr> woglinde: AFAIU it will do DHCP by default on eth0 while also the usb0 will be active, no editing necessary.
Jun 17 07:12:58 <araru> ok let me try
Jun 17 13:34:08 <azv4> What would mouser call this: http://www.reichelt.de/Female-Connectors/BL-2X25G-2-54/3/index.html?&ACTION=3&LA=5&ARTICLE=6080&GROUPID=3221&artnr=BL+2X25G+2%2C54
Jun 17 13:34:23 <av500> female pin header
Jun 17 13:34:39 <agmlego> female pin header, 2x25
Jun 17 13:34:50 <agmlego> Not breakaway style.
Jun 17 13:34:55 <azv4> yea Id call it that too
Jun 17 13:34:58 <azv4> what would MOUSER CALL IT?
Jun 17 13:35:05 <agmlego> female pin header, 2x25
Jun 17 13:35:19 <agmlego> With 0.1" pitch.
Jun 17 13:35:22 <azv4> they dont stock it then...
Jun 17 13:35:28 <azv4> .1" is same as 2.54 correct?
Jun 17 13:35:29 <agmlego> Not surprising.
Jun 17 13:35:36 <agmlego> 2x25 is pretty uncommon.
Jun 17 13:35:40 <agmlego> azv4: Yes.
Jun 17 13:35:46 <av500> http://www.ebay.com/itm/3pcs-2x40-Pin-2-54-mm-Dual-Row-Female-Pin-Header-/221377669864?pt=LH_DefaultDomain_0&hash=item338b232ae8
Jun 17 13:36:04 <azv4> av500, that isnt right size
Jun 17 13:36:08 <av500> so?
Jun 17 13:36:12 <av500> they can be cut
Jun 17 13:36:16 <av500> easily
Jun 17 13:36:17 <agmlego> So picky. ;-P
Jun 17 13:36:20 <av500> I do that all the time
Jun 17 13:36:28 <azv4> not sure I have anything around to cut that
Jun 17 13:36:34 <av500> nothing?
Jun 17 13:36:40 <av500> you live in the US?
Jun 17 13:36:45 <azv4> hmm, lighter and a knife!
Jun 17 13:36:54 <av500> and a credit card
Jun 17 13:37:12 <av500> since you can order from mouser
Jun 17 13:37:13 <azv4> yes I live in USA, else I would completed my http://www.reichelt.de/ order in the 3 minutes it took to make it
Jun 17 13:37:33 <azv4> instead I am 4 hours into trying to find same parts from this part list in America and its making me crazy
Jun 17 13:38:38 <agmlego> azv4: http://www.mouser.com/Connectors/Headers-Wire-Housings/_/N-ay0lo?P=1ytkn06Z1z0z63xZ1z0wxp6Z1yzv7x1Z1z0wv1v
Jun 17 13:38:51 <agmlego> Seriously, took me all of like a  minute to drill down to them. ;-P
Jun 17 13:39:13 <azv4> seriously I failed for 10 minutes on this item alone
Jun 17 13:39:26 <azv4> I do appreciate your effort
Jun 17 13:39:31 <agmlego> YOu might need some practice using part filters then.
Jun 17 13:39:35 <agmlego> No problem./
Jun 17 13:39:36 <azv4> $5.31 each.,.. I hope they are good in bed
Jun 17 13:39:45 <av500> azv4: hence my ebay link
Jun 17 13:39:49 <agmlego> Hey, you are the one looking for super-rare parts.
Jun 17 13:40:04 <av500> rare?
Jun 17 13:40:15 <azv4> yea Im trying to figure out why this is considered rare
Jun 17 13:40:20 <av500> its not
Jun 17 13:40:59 <av500> anyway, get 2x24 and cut
Jun 17 13:41:04 <av500> er 2x40
Jun 17 13:41:08 <azv4> how about this one?  SL 1X40G 2,54
Jun 17 13:41:19 <av500> 1x?
Jun 17 13:41:22 <av500> almost
Jun 17 13:41:30 <azv4> I need one of those too
Jun 17 13:41:30 <azv4> SL 1X40G 2,54
Jun 17 13:41:37 <av500> 1x40
Jun 17 13:42:06 <azv4> This is what the part list calls for: 1-row SIL Headers (9 pins required)    reichelt.de park# SL 1X40G 2,54
Jun 17 13:42:59 <azv4> ahh nevermind, I can get those anywhere
Jun 17 13:43:06 <azv4> in fact I have some already
Jun 17 13:43:26 <av500> dont we all? :)
Jun 17 13:43:40 <av500> you can always steal them from your arduino
Jun 17 13:43:51 <azv4> some of these Mouser prices seem crazy high
Jun 17 13:44:09 <azv4> they want 2.18 each for 40 pin SIL each?
Jun 17 13:44:09 <av500> yes
Jun 17 13:44:31 <azv4> I paid $8.50 for 20 of them I think
Jun 17 13:45:02 <av500> I paid $2.40 for 10
Jun 17 13:45:31 <agmlego> Mouser is not the cheapest source of parts.
Jun 17 13:45:32 <azv4> nice, mouser markup?  10000%!
Jun 17 13:45:46 <azv4> hmm, maybe I should take 4 hours to do this cart on another site
Jun 17 13:45:54 <av500> correction, I paid $1.55
Jun 17 13:46:04 <av500> for 10
Jun 17 13:46:22 <av500> http://www.ebay.com/itm/251463905682
Jun 17 13:46:51 <azv4> hmm, not sure I need male or female
Jun 17 13:46:52 <agmlego> azv4: You use Mouser or Digikey or the like because they have nice interfaces, sell good products, and sell the same product every time you order the same part number. *Not* for cost.
Jun 17 13:46:56 <azv4> better take a closer look
Jun 17 13:47:07 <agmlego> If you want to save money, use eBay.
Jun 17 13:47:12 <av500> agmlego: and have one of each
Jun 17 13:47:16 <agmlego> But caveat emptor.
Jun 17 13:47:59 <av500> the risk of losing $1.55 is small
Jun 17 13:48:26 <av500> http://www.ebay.com/itm/12PCS-New-Multicolor-2-54mm-1-40Pin-Male-Single-Row-Pin-Header-for-Arduino-DIY/261828426180
Jun 17 13:48:49 <azv4> oooo, multi colored!  I like!
Jun 17 13:48:55 <av500> :)
Jun 17 13:49:54 <azv4> estimated delivery: sometime in 2015, maybe 2016!  Oh well, they usually pretty fast shipping from CHina these days it seems
Jun 17 13:50:06 <av500> I get ~2-3week these days
Jun 17 13:55:42 <azv4> now I just need to find a resistor network, 1kohm, 4+1common
Jun 17 13:56:22 <av500> what are you building?
Jun 17 13:56:32 <av500> azv4: smd?
Jun 17 13:56:42 <azv4> is SIL the same as DIP, Radial SIP?
Jun 17 13:56:56 <azv4> Single In Line, through hole
Jun 17 13:57:00 <azv4> I think that is what I need
Jun 17 13:57:10 <agmlego> Yeah,. SIL != DIP
Jun 17 13:57:10 <av500> so use 4 normals resistors
Jun 17 13:57:22 <av500> and solder a wire across and into pin 5
Jun 17 13:57:22 <azv4> http://www.reichelt.de/4-Resistors-5-Pins/SIL-5-4-1-0K/3/index.html?&ACTION=3&LA=5&ARTICLE=17670&GROUPID=4496&artnr=SIL+5-4+1%2C0K
Jun 17 13:57:39 <azv4> Im such a noob, Id probably screw it up
Jun 17 13:57:48 <azv4> wire across the grounds?
Jun 17 13:57:52 <azv4> err the -?
Jun 17 13:58:00 <agmlego> azv4: YOu know what the polite thing to do is, now that you have done all this work?
Jun 17 13:58:09 <av500> http://www.cpcwiki.eu/imgs/thumb/b/bd/DIYNR101.jpg/300px-DIYNR101.jpg
Jun 17 13:58:15 <av500> azv4: ^^^
Jun 17 13:58:23 <agmlego> azv4: Send an email to the project maintainer with the Mouser part numbers, as a crossreference.
Jun 17 13:58:35 <azv4> agmlego, I am compiling that list
Jun 17 13:58:45 <azv4> agmlego, and it will be added to the project detail website
Jun 17 13:58:47 <av500> what are you building?
Jun 17 13:58:49 <agmlego> Great.
Jun 17 13:58:55 <azv4> assuming I can find all of the right parts!
Jun 17 13:58:58 <azv4> MidiBox
Jun 17 13:59:05 <azv4> MidiBoxNG
Jun 17 13:59:15 <azv4> http://ucapps.de/
Jun 17 13:59:28 <av500> ah
Jun 17 14:02:46 <azv4> so what does a resistor network do?  provide variable resistance depending on which - pin is addressed?
Jun 17 14:03:04 <agmlego> It can.
Jun 17 14:03:06 <azv4> is there a + and - on resistors?
Jun 17 14:03:13 <azv4> can they go either way?
Jun 17 14:03:18 <agmlego> Or it can literally be just a package with a bunch of individual resistors.
Jun 17 14:03:26 <agmlego> azv4: Resistors are not polarized.
Jun 17 14:03:32 <azv4> ok thanks
Jun 17 14:06:40 <azv4> Does this: http://www.ebay.com/itm/50-PCS-A05-102G-SIP-5-A-102G-1K-ohm-1KR-4-Commoned-Resistor-Network-Array-5-PIN-/291175323318?pt=LH_DefaultDomain_0&hash=item43cb66d6b6
Jun 17 14:06:51 <azv4> look the same as: http://www.reichelt.de/4-Resistors-5-Pins/SIL-5-4-1-0K/3/index.html?&ACTION=3&LA=5&ARTICLE=17670&GROUPID=4496&artnr=SIL+5-4+1%2C0K
Jun 17 14:07:46 <mjgardes> SIL resistor networks do have a specific orientation
Jun 17 14:07:51 <agmlego> True.
Jun 17 14:09:07 <azv4> Any thoughts on above links?
Jun 17 14:11:21 <agmlego> azv4: Not at this time, no. Work, you know.
Jun 17 14:11:31 <av500> azv4: same
Jun 17 14:11:44 <azv4> I think I found the right thing
Jun 17 14:11:49 <av500> but as said, you can just solder 4 1k resistors
Jun 17 14:11:58 <azv4> av500, not sure I trust myself yet on that one
Jun 17 14:12:03 <av500> if you just need a few...
Jun 17 14:12:28 <azv4> I can probably do it right, but just not confident enough yet because I don't understand the exact signal path and whatnot, I know its simple, but Im soooo new
Jun 17 14:13:27 <av500> well, you can practice
Jun 17 14:13:34 <av500> you need to buy a multimeter anyway
Jun 17 14:13:39 <av500> to check what you are doing
Jun 17 14:13:44 <azv4> I have one
Jun 17 14:13:51 <av500> so you can easily measure what you did
Jun 17 14:13:52 <azv4> but I dont know how the array should behave
Jun 17 14:13:56 <av500> well
Jun 17 14:14:07 <av500> its 1k from the common point
Jun 17 14:14:11 <azv4> this project tells me what to do, but not what Im doing
Jun 17 14:14:20 <azv4> then an additional 1k for each pin I move over?
Jun 17 14:14:36 <av500> http://www.talkingelectronics.com/projects/Testing%20Electronic%20Components/images/ResistorNetwork.gif
Jun 17 14:14:41 <av500> not additional
Jun 17 14:14:47 <av500> see the upper image
Jun 17 14:14:59 <av500>  http://www.cpcwiki.eu/imgs/thumb/b/bd/DIYNR101.jpg/300px-DIYNR101.jpg
Jun 17 14:15:01 <av500> or this
Jun 17 14:15:45 <azv4> so its just another way to wire up multiple resistors to save space?
Jun 17 14:16:03 <agmlego> Yes.
Jun 17 14:16:23 <av500> yes
Jun 17 14:17:07 <av500> azv4: where are the schematics to what you are building?
Jun 17 14:17:37 <azv4> http://ucapps.de/
Jun 17 14:17:54 <av500> there are many schematics there
Jun 17 14:18:11 <azv4> well it wont let me link to the direct image, not sure why not
Jun 17 14:18:25 <av500> bad web design
Jun 17 14:18:29 <av500> somebody was too clever
Jun 17 14:18:33 <azv4> frames I think
Jun 17 14:18:37 <av500> MBHP_CORE_STM32F4_V1
Jun 17 14:18:41 <av500> I guess
Jun 17 14:18:57 <av500> http://ucapps.de/mbhp/mbhp_core_stm32f4_fheaders.jpg
Jun 17 14:19:24 <av500> there is no reason to use that array there
Jun 17 14:19:30 <av500> on such a huge board
Jun 17 14:19:40 <av500> or to buy 50 to get one
Jun 17 14:20:40 <av500> somebody was too clever again
Jun 17 14:32:09 <azv4> I found someone selling 15 of them for $2
Jun 17 14:32:28 <azv4> I'm making 30 of these boards, so I want them to be as neat and clean as possible
Jun 17 14:32:57 <azv4> well the initial batch is only 5
Jun 17 14:33:26 <azv4> but I want to do 30 next round
Jun 17 14:45:46 <av500> ah
Jun 17 15:05:53 <azv4> looks like total cost per unit is going to be around $50
Jun 17 15:05:56 <azv4> not to bad
Jun 17 17:43:34 <cityLights> rcn-ee: I noticed that connman doesn't play well with the micro usb g_ether
Jun 17 17:44:10 <cityLights> I see your boot script uses ifconfig to set the IP adrress and run a dhcp server
Jun 17 17:45:11 <cityLights> connman offer both of these, so I tried to set it up. my problem it that the USB0 device keeps getting different MAC addresses
Jun 17 17:45:15 <rcn-ee> cityLights, it's changed a lot this last week..
Jun 17 17:45:34 <rcn-ee> https://github.com/RobertCNelson/boot-scripts/blob/master/boot/autoconfigure_usb0.sh
Jun 17 17:46:14 <rcn-ee> usb0 should get the mac from the spare mac address in eeprom:
Jun 17 17:46:41 <cityLights> host_addr=${cpsw_1_mac} |
Jun 17 17:47:15 <cityLights> yet I tested and it keeps getting different address
Jun 17 17:47:20 <rcn-ee> there's a backup value now too: https://github.com/RobertCNelson/boot-scripts/blob/master/boot/am335x_evm.sh#L93 (the tre was having issues)
Jun 17 17:49:07 <cityLights> can you please check that the mac changes every boot?
Jun 17 17:49:38 <rcn-ee> cityLights, wait.. https://gist.github.com/RobertCNelson/28571b0f8efebe8882f2
Jun 17 17:49:54 <rcn-ee> this is what your running into.. usb0 on the "bbb" is random...
Jun 17 17:52:26 <rcn-ee> cityLights, how should we calculate "dev_addr" ?
Jun 17 17:52:35 <cityLights> was this fixed? is it a known issue?
Jun 17 17:53:16 <rcn-ee> cityLights, issue, you should turned the flash light on.. ;)
Jun 17 17:53:42 <rcn-ee> updated: https://gist.github.com/RobertCNelson/28571b0f8efebe8882f2 ... so... should we just +1 host_addr for dev_addr???
Jun 17 17:54:57 <rcn-ee> maybe just invert the last nibble?
Jun 17 17:55:10 <cityLights> ok, please tell if I can be of any help
Jun 17 17:56:01 <cityLights> also, I am working with the connman maintainer to allow a better solution to the access point configuration I wrote
Jun 17 17:56:09 <rcn-ee> cool!
Jun 17 17:57:11 <cityLights> he already introduced a fix to spin-up the access point on a second device , while wlan0 is connected to the home network
Jun 17 17:57:58 <cityLights> I hope we can solve the g_multi  issue with udev and connman as dhcp server
Jun 17 18:01:02 <rcn-ee> cityLights, quick hack: https://github.com/RobertCNelson/boot-scripts/commit/f9d312a7c51eb8ea25fc67304cfd47b208ee4afd
Jun 17 18:02:18 <cityLights> wow rcn-ee you wrote a lot of lines with the new autoconfig usb0
Jun 17 18:03:04 <cityLights> lets test it
Jun 17 18:03:21 <rcn-ee> nope, that's all Per Dalgas Jakobsen's work... now you can change the usb0 default addres from /etc/network/interfaces ...
Jun 17 18:11:04 <cityLights> what is Dalgas Jakobsen role? what is he building?
Jun 17 18:12:57 <cityLights> SOLVED
Jun 17 18:13:00 <cityLights> thanks
Jun 17 18:13:12 <cityLights> I ment the mac is constant
Jun 17 18:13:24 <cityLights> so connamn can handle it now
Jun 17 18:14:39 <rcn-ee> he just didn't like the hardcoded usb0 ip address.. ;)
Jun 17 18:14:58 <cityLights> ok, I will send a file we need to add to have connman deal with it, then we wont need dnsmasq and we wont have subnet collisions
Jun 17 18:15:10 <cityLights> is he here?
Jun 17 18:15:17 <cityLights> this all so fresh to me
Jun 17 18:16:38 <rcn-ee> i don't think he's been on irc before... he just sent me a patch last week to dynamcily update usb0's configuration.. over a few emails it ended up with that massive patch. ;)
Jun 17 18:19:07 <cityLights> well, how should I say this... connman does all of it....
Jun 17 18:19:12 <cityLights> and udev
Jun 17 18:37:25 <stt_michael> rcn-ee, that hard-coded address is *** if you should want more than one beagle plugged in at once .. and why not?!
Jun 17 18:43:42 <rcn-ee> stt_michael, agree 100%...
Jun 17 18:44:45 <rcn-ee> i started looking into xor'ing the last 2 digits, turns out that's a pain and cycle wastish.. so i'm just going to check the last digit and have 3 options, 0, 1, 2 on has to not match..
Jun 17 18:49:45 <rcn-ee> stt_michael, little nasty: https://gist.github.com/RobertCNelson/28571b0f8efebe8882f2#file-solution  but it should work. ;)
Jun 17 18:50:08 <rcn-ee> remember only the bbb, see's dev_mac...
Jun 17 18:50:51 <stt_michael> and that sorts out getting dhcp right too .. or is cityLights on that too :D
Jun 17 18:51:24 <rcn-ee> yeap, it still helps cityLights as it's static...
Jun 17 18:52:06 <rcn-ee> (the mac address's are hardlocked at ti's factory, so it would take a lot of work to have them change randomly..)
Jun 17 18:52:51 <stt_michael> yeahno
Jun 17 18:53:10 <stt_michael> OMFG .. I just 'saved' a 16Mb PDF to /dev/null from thunderbird .. Awesome lol :D (intentionally!)
Jun 17 18:53:46 <stt_michael> I shall remember that to keep my 'sent items' under control :)
Jun 17 18:54:19 <stt_michael> ok time to gtfo ;)
Jun 17 18:54:26 <stt_michael> bbiab
Jun 17 18:55:32 <rcn-ee> stt_michael, cityLights one more mac change.. https://github.com/RobertCNelson/boot-scripts/commit/38c0372a567cf0d4a3c3cee0770b360e4358ea19
Jun 17 18:55:37 <rcn-ee> i think we are golden now..
Jun 17 19:36:26 <veremit> rcn-ee : looks promising :)
Jun 17 19:43:59 <jkridner> veremit, rcn-ee: where are you using the cpsw macs now?
Jun 17 19:44:08 <jkridner> USB?
Jun 17 19:44:29 <jkridner> is this somehow fixing the IP address conflict too?
Jun 17 19:44:49 <jkridner> (from the fixed DHCP host contents)
Jun 17 19:44:56 <rcn-ee_> jkridner, we actually need 3 mac's.. with this change, dmesg | grep -i mac
Jun 17 19:45:01 <rcn-ee_> will be constant between reboots..
Jun 17 19:45:15 <jkridner> that's good.
Jun 17 19:45:18 <rcn-ee_> the third mac is the usb0 from the bbb (we pass cpsw1 to the host on the usb end..)
Jun 17 19:45:24 <jkridner> oh, right.
Jun 17 19:45:51 <jkridner> where is the 3rd one coming from?
Jun 17 19:45:52 <rcn-ee_> it had always been random, but cityLights work with connman needs it constant..
Jun 17 19:46:20 <jkridner> xoring?
Jun 17 19:46:21 <rcn-ee_> i'm just checking the last character of the efuse values, and setting it 0, 1, or 2..
Jun 17 19:46:30 <rcn-ee_> xorging was lookign to be too slow...
Jun 17 19:47:06 <jkridner> just appending?
Jun 17 19:47:18 <jkridner> last byte?
Jun 17 19:47:27 <rcn-ee_> yeap, cutting the last digit off and appending a value not used..
Jun 17 19:48:27 <jkridner> ok, so leaving the ones there and with 3 options, one of them will be unique.
Jun 17 19:48:46 <jkridner> and predictable.
Jun 17 19:48:47 <rcn-ee_> correct.. (i assume the mac-prefix will be the same of course. ;))
Jun 17 19:49:25 <jkridner> even if not, the other ids can only consume 2 of 0, 1 and 2.
Jun 17 19:49:50 <jkridner> nice.
Jun 17 19:50:22 <jkridner> Tre should be able to use this too, no?
Jun 17 19:50:31 <rcn-ee_> it does. ;)
Jun 17 19:51:17 <rcn-ee_> the tre posted here: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2015-06-15  is mapped to the same boot script as the bbb..
Jun 17 19:51:32 <rcn-ee_> brb, home -> work...
Jun 17 19:51:47 <jkridner> btw, why is the script using 3.14 if we are jumping from 3.8.x to 4.1?
Jun 17 19:52:39 <jkridner> seems like we still have to support new boards, etc. with 3.8 until the jump to 4.1 is complete.  thought we were jumping over 3.14 for now unless a real need arose (like USB fixes).
Jun 17 20:01:33 <rcn-ee> jkridner, just moved it to 4.1 this morning.. fixed the eMMC flashing bug...
Jun 17 20:01:50 <jkridner> cool!
Jun 17 20:01:57 <rcn-ee> are you ready for the overlay img tester image?
Jun 17 20:02:01 <jkridner> I will make sure the default is 4.1 as well
Jun 17 20:02:18 <jkridner> "overlay img tester image"?
Jun 17 20:02:43 <rcn-ee> for the build boot, img -> bank of bb's with capes attached. ;)
Jun 17 20:03:03 <jkridner> rcn-ee: switched default to 4.1. :-)
Jun 17 20:03:32 <jkridner> I started gathering the boards today, but haven't quite figured out how I want to network or flash them.
Jun 17 20:03:56 <jkridner> Seems it needs to scale...
Jun 17 20:04:14 <jkridner> I need to pay attention to a call right now, but will get back on that.
Jun 17 20:04:23 <rcn-ee> well, the bbb+ 4 port relay would give you 4. ;)
Jun 17 20:15:11 <veremit> heh
Jun 17 20:38:17 <jkridner> rcn-ee: remind me what the bbb+ 4 port relay is.
Jun 17 20:38:59 <rcn-ee> it's the relay cape. ;) 4 relay's...
Jun 17 20:40:12 <rcn-ee> with a 4 port hub, you could have one bbb, flashing up to 4 bb's over usb...
Jun 17 21:47:32 <veremit> rcn-ee .. so 4 relays to control power, and 4 usb's to program?
Jun 17 21:48:01 <veremit> once you've done 4.. you can then program 16 by the same method :D
Jun 17 21:48:29 <rcn-ee> and 4 poor, ftdi's for serial logging, so we'd need an 8 port hub... and this all over musb... what could go wrong? ;)
Jun 17 21:49:04 <veremit> hahaha
Jun 17 21:53:31 <jkridner> rcn-ee: ok, now to spend 10 minutes looking at how to wire up all these Bones.
Jun 17 21:53:50 <jkridner> oh, the relay cape.
Jun 17 21:54:21 <jkridner> I do have a handful of those.... don't really want to buy a bunch of hubs...
Jun 17 21:55:02 <rcn-ee> we might be able to redirect the kernel log over usb...
Jun 17 21:55:20 <jkridner> I wonder if I can power every so many boards and just go from USB to USB and "trust" them to boot. (using dmesg to catch the output)
Jun 17 21:55:20 <rcn-ee> err wait, usb would provide power...
Jun 17 21:55:36 <jkridner> yeah, we'd only get a boot log on success...
Jun 17 21:55:50 <jkridner> but, I could likely put the boards with the simplest capes up front....
Jun 17 21:55:54 <jkridner> and just go down the line.
Jun 17 21:56:06 <jkridner> but, I'd need a way to power cycle the USB on the BeagleBone....
Jun 17 21:56:18 <jkridner> I thought that might have been possible.
Jun 17 21:56:33 * jkridner takes a quick look at the schematic.
Jun 17 21:56:35 <rcn-ee> err wait, let's cut a usb cable, run the 5volt thru the relay cape. ;)
Jun 17 21:57:01 <rcn-ee> usb-flashing and usb-console (we coudl append console=/dev/ttyUSB0 and get the serial boot)
Jun 17 21:58:22 <jkridner> well, that still won't have the log unless it is successful in booting the kernel, so why not use 'dmesg'?
Jun 17 21:59:08 <jkridner> because there are so many capes, the daisy-chain solution really appeals to me vs. needing N relay capes.
Jun 17 21:59:17 <jkridner> I do have 8 of those capes though.
Jun 17 21:59:30 <jkridner> wouldn't look forward to modding the cables.
Jun 17 21:59:54 <rcn-ee> it would be the simplist, as only one cape per test device...
Jun 17 22:00:03 <rcn-ee> one 'cable'..
Jun 17 22:00:35 <jkridner> USB1_DRVVBUS controls power to the USB device.
Jun 17 22:01:33 * jkridner looks up "TPS2051"
Jun 17 22:02:15 <jkridner> GPIO3_13 drives USB1_DRVVBUS
Jun 17 22:04:41 <veremit> o,o
Jun 17 22:09:00 <darknighte> jkridner: heh, on the BBB, how many endpoints are supported by the musb OTG controllers?
Jun 17 22:56:29 <veremit> what shift are you on now, rcn-ee ?!
Jun 18 02:45:48 <Spirilis> whew, ok, crash course in USB booting complete.
Jun 18 02:46:17 <Spirilis> had no SD card handy so I had to write a debian 8.1 image to USB stick, boot, then try to copy it all over.  was successful after the 3rd attempt or so :)
Jun 18 02:46:59 <myself> sometimes that's the best kind of course ;)
Jun 18 02:48:04 <Spirilis> yep yep you never learn things by doing it the easy way :)
