**** BEGIN LOGGING AT Thu Jan 14 02:59:58 2016 Jan 14 03:02:57 i understand that, surprisingly Jan 14 03:03:06 hehe Jan 14 03:14:26 note that the memory range(s) declared in device tree should start and end on 4KB page boundaries, otherwise you'll have trouble mmap()ing them Jan 14 03:14:52 (I ran into this issue with PWMSS submodules) Jan 14 03:25:05 Was trying to install linux-headers-3.8.13-bone69 running debian on my rev C beaglebone black and noticed there are no linux-headers .deb files on Robert Nelsons http://rcn-ee.net/deb area which is where all howtos reference. Did all of this move? All I see in every directory is a patch.diff.gz file, no .deb files anywhere. Any ideas? Jan 14 03:26:43 http://repos.rcn-ee.com/debian/ is his debian repository... normally that should already be in your /etc/apt/sources.list so you can just apt-get install the package you want Jan 14 03:30:15 apt-cache search -n linux-headers-.*-bone Jan 14 03:31:49 (don't forget to do apt-get update first to update your package list if you haven't done so already) Jan 14 03:32:39 Hi zmatt thanks for replying -- I can add http://repos.rcn-e.com/debian/ wheezy-bbb main Jan 14 03:32:52 add that line to /etc/apt/sources.list and apt-get update? Jan 14 03:33:05 if it's not there yet, what kind of weird/ancient system do you have? Jan 14 03:34:42 also, "wheezy-bbb" ? afaik it should be just "wheezy", though I don't know much about ancient distro versions so maybe I'm wrong Jan 14 03:40:38 Sorry -- I was trying a few things. Jan 14 03:42:59 zmatt: have you guys ruled out SQ issues on the LCD clocks? Jan 14 03:43:09 zmatt -- I think I got it. Jan 14 03:43:27 ds2: yes Jan 14 03:43:30 I added this line and now linux-headers appears available Jan 14 03:43:45 zmatt: how are you verifying that? Jan 14 03:43:49 deb [arch=armhf] http://rcn-ee.net/repos/debian wheezy main Jan 14 03:43:51 eye diagram? Jan 14 03:44:12 ds2: because the hypothesis is incompatible with the symptoms Jan 14 03:44:13 Thanks for the tip zmatt. Jan 14 03:45:13 and apt-get install linux-headers-3.8.13-bone69 is now working. Thanks again! Jan 14 03:49:30 ds2: also, if it'd be having signal quality issues at 65 MHz I doubt it would be working at all at nearly double that pixel clock rate... it does Jan 14 04:04:48 good afternoon, I am seeking some assistance with wifi on Linux beaglebone 3.8.13-bone79 Jan 14 04:47:32 what are the symtoms again? Jan 14 05:07:23 ARGH, why the fuck does the linux kernel have to make everything so complicated... do I really have to patch it to add some bullshit codec just to be able to enable use of McASP... Jan 14 05:07:35 ds2: go read logs or something Jan 14 06:53:34 accidentally I have formatted my beaglebone black emmc.is there a way to recover it Jan 14 06:53:49 just reflash it Jan 14 06:54:24 how to do that Jan 14 06:54:29 download flasher Jan 14 06:54:31 download a flasher image, put it on a μSD card, boot from it Jan 14 06:54:48 or use the usb flasher Jan 14 06:54:56 or just run from uSD Jan 14 06:55:52 http://beagleboard.org/latest-images Jan 14 06:56:02 will the above has flash image Jan 14 06:59:46 where can i get flash image Jan 14 07:58:39 hi Jan 14 08:59:23 Hi Everyone Jan 14 08:59:45 Wanted to know if Windows10 image is available for BBB. Jan 14 09:02:05 lol Jan 14 09:25:47 what about mise home?) Jan 14 09:26:33 sorry Jan 14 09:39:17 zmatt, hello Jan 14 09:39:39 and hello to all Jan 14 10:31:03 hi, I'm a bbb newbie. Just build a buildroot image and successfullt tested it on microSD. wanted to flash it on eMMC with no success Jan 14 10:32:03 I started pressin boot button wile not powered, powered on while keeping pressed until the led bank flashed and released but buildroot boots up Jan 14 10:39:49 ok, looking at http://www.crashcourse.ca/wiki/index.php/BBB_software_update_process will try it and eventually get back for more help. sorry for the noise Jan 14 10:41:09 david-e feel free to idle & ask questions .. we're often a bit busy but someone usually answers Jan 14 10:47:50 can not make my build u-boot work in qemu Jan 14 10:48:10 * Spidler blipps in Jan 14 10:48:12 hi all Jan 14 10:48:23 ( Almost a week since last in the office, ahh, field work ) Jan 14 10:48:55 And for a fun project, I've deployed a BBB in temperatures around -25 now. Lets see how that works out. Jan 14 10:52:48 brrr Jan 14 10:52:50 david-e: look at the debian flashing script. I doubt buildroot ships with one out of the box. Jan 14 10:54:33 https://github.com/RobertCNelson/boot-scripts/tree/master/tools Jan 14 11:02:48 tbr: thanx alot Jan 14 11:04:51 Spidler: cool project! *rimshot* Jan 14 11:05:01 * Spidler snickers Jan 14 11:05:21 tbr: Lets see how they work out, I'm a bit concerned that the heat from the BBB will cause moisture condensation Jan 14 11:06:03 *nod* Jan 14 11:06:25 The good part is that from -5 and down you have almost zero moisture in the air :) Jan 14 11:19:02 tbr: looked at the repo: lots of script, not documented. will try to dig it more. Any sample usage links or similar? Jan 14 11:19:42 tbr: I guess it should not be too complicated: I should have all the pieces Jan 14 11:20:44 david-e: https://github.com/RobertCNelson/boot-scripts/tree/master/tools/eMMC explains which scripts do what Jan 14 11:21:04 look at the scripts, they don't perform rocket-surgery Jan 14 11:21:39 tbr: yes, I did see it. will focus on those, thanx Jan 14 11:22:22 Mmm Jan 14 11:22:51 My own eMMC flasher simply boots a system and does xzcat and onto the onboard MMC :-) Jan 14 11:23:15 Most definitely not rocket surgery, and most definitely leads to an adorably bricked device if you pull the power halfway through. Jan 14 11:23:43 ack, that's the quick way :) Jan 14 11:23:54 bonus points if you boot the SD RO Jan 14 11:24:19 or make the mounts RO before flashing Jan 14 11:25:42 Mmm Jan 14 11:26:11 My / is a squashfs and /data is ext4 still rw, but since there's nothing writing there, I'm not too concerned Jan 14 11:26:31 I guess in theory the /boot could get fucked up since its on vfat with all that that entails Jan 14 11:28:54 hope you're not trying to scare me :) Jan 14 11:29:05 Nah Jan 14 11:29:07 once it's bricked there's no way back? Jan 14 11:29:18 You just reboot again on the sd card :) Jan 14 11:29:31 so it's no that fun :) Jan 14 11:29:32 no, there is no way to permanently b0rk the board that way Jan 14 11:29:48 And if you _really_ screw it up, you can plug in a serial connector and send a bootloader blob directly to the CPU Jan 14 11:30:01 That one is a bit hairier, but generally, you can't brick it permanently from software alone Jan 14 11:30:12 I do have the cable so I should be fine Jan 14 11:30:27 Yeah Jan 14 11:30:47 What you need to make sure of is that you get the boot loader script correct, I've seen that a few times Jan 14 11:31:14 When fex. the SD card bootloader script will accidentally(or not) load the kernel + initrd + filesystem from the eMMC Jan 14 11:31:25 -that- can be awesomely confusing! Jan 14 11:31:35 "I keep pressing the button and nothing happens" Jan 14 11:32:47 yeah, that happened with old factory images. insert SD card and emmc boot would bork Jan 14 11:33:00 or it would boot the sd content instead Jan 14 11:35:10 Yea Jan 14 11:36:38 Confusing, not the end of the world, but I know I spent a fair amount of time trying to figure it out back in the day. Jan 14 12:25:29 Hello everybody Jan 14 12:26:00 I am new here and I am a beginner in programming Jan 14 12:26:17 I am using a beaglebone black board to do some exercices Jan 14 12:26:52 and my question is: Is there a way to put an OS on the Beaglebone black which is lighter? Jan 14 12:27:09 It takes 1 minutes and 20 seconds to start my application there Jan 14 12:31:20 Hi Jan 14 12:33:07 Mehdi_: if it takes 1 minute and 20 seconds to start your application, then something fundamentally is wrong. you should try to figure out why it is so slow and not blame the OS for i Jan 14 12:33:11 it Jan 14 12:33:12 Mehdi_.. you're not really going to improve mucuh on that unless you code baremetal Jan 14 12:33:24 er... Jan 14 12:33:27 veremit: wrong Jan 14 12:33:31 oh .. we talkin about OS startup or appliction Jan 14 12:33:40 KotH.. how fast does debian boot on your system?! :P Jan 14 12:33:48 veremit: depending on what you do and how you do it, you can optimize a linux to boot into a qt app within less than a second Jan 14 12:34:07 that said ..if you're running a ubntu image ... Jan 14 12:34:15 put lxqt on it :D Jan 14 12:34:16 ubuntu != debian Jan 14 12:34:25 also, it's possible with both, if you knwo what you are doing Jan 14 12:34:32 KotH .. good grief do I have to go around that loop again Jan 14 12:34:38 yes Jan 14 12:34:56 ok back to work then .. lol ;P Jan 14 12:35:09 because i hate general statements that are based on not understanding what the fundamental mechanics of the problem is Jan 14 12:36:16 thank you everyone Jan 14 12:55:34 KotH: can we discuss on skype? Jan 14 12:55:38 no Jan 14 12:55:45 if you have questions, ask them here Jan 14 12:55:53 thank you Jan 14 12:56:05 i just bought a new display of 1.44" Jan 14 12:56:20 and I want to make it work with my BBB board Jan 14 12:56:39 do you have a link where I can see how I can do it? Jan 14 12:56:49 or anyone else Jan 14 12:56:53 thank you very much Jan 14 12:57:13 there is Debian on my BBB installed Jan 14 12:57:59 that's not debian specific Jan 14 12:58:09 and it depends on what interface your display has Jan 14 12:58:15 is the software leveling procedure, http://processors.wiki.ti.com/index.php/AM335x_DDR_PHY_register_configuration_for_DDR3_using_Software_Leveling Jan 14 12:58:29 necessary if the board design only uses one DRAM device? Jan 14 12:58:40 namely, just like the BBB? Jan 14 12:59:37 the discussion of the leveling function in the ddr controller in the am335x errata sheet seems to say it is only used when you have multiple dram devices. Jan 14 12:59:52 * KotH doesnt know Jan 14 13:00:29 My display is an SPI 128 x 128 pixels Jan 14 13:02:44 Mehdi_: most people i know, accesses these small spi/i2c displays directly from the application, not using any graphics library Jan 14 13:03:41 the thing is that I never used the board befor or any thing like that :( Jan 14 13:04:24 which application are you talking about please? Jan 14 13:04:36 the one you want to run on the bbb Jan 14 13:05:00 do i need to plug the BBB on the TV to see it first? Jan 14 13:05:28 I thought there was some spi-framebuffer thing Jan 14 13:08:49 <_av500_> Mehdi_ http://matthewcmcmillan.blogspot.de/2014/09/experimenting-with-beaglebone-black-and-tft.html Jan 14 13:08:52 <_av500_> Mehdi_: ^^ Jan 14 13:08:53 https://github.com/notro/fbtft/wiki/BeagleBone-Black Jan 14 13:09:08 <_av500_> https://www.google.de/search?q=bbb+spi+tft Jan 14 13:09:35 thank you very much Jan 14 13:15:48 yates: that's not exactly what it says, but yes the summary in the errata is a bit misleading. leveling depends on the propagation times of the three signal groups (cmd/addr and the two byte lanes), both relative to each other and (for byte lanes) absolute, and delays introduced by the memory device itself. It should be performed for any combination of PCB, ddr3 device(s), and ddr3 frequency Jan 14 13:16:42 fortunately that's just a simple matter of running the program and copy/pasting the values it outputs Jan 14 13:21:31 in omap_hwmod in the kernel there is a flag called _HWMOD_STATE_ENABLED_AT_INIT, that can be used for IP cores that gets enabled in the boot loader and needs to stay on thoughout the kernel init, like UART0. How do I set that flag? Is it possible to do from the DT? Jan 14 13:27:25 try: ti,no-idle-on-init; Jan 14 13:30:47 Aha! Yeah, I'll try that! Jan 14 13:36:19 you might want ti,no-reset-on-init; also Jan 14 13:37:50 ah nm, it looks like omap_hwmod doesn't know how to reset lcdc anyway Jan 14 14:19:00 zmatt: That actually worked! Jan 14 14:19:11 \o/ Jan 14 14:28:33 Hello Jan 14 14:29:38 What is different beaglebon rev.A6 to rev.A6A Jan 14 14:30:12 What is different beaglebon rev.A6 to rev.A6A? Jan 14 14:30:59 korean: http://elinux.org/Beagleboard:BeagleBoneBlack#Revision_A6A Jan 14 14:31:54 It's actually the first hit on google when you search for "beaglebone revisions" . Jan 14 14:34:18 sorry. i don't search for Google. beaglebone White A6 to A6A. Jan 14 14:34:30 * samael wonders what's the reason the package irqbalance is installed on the BeagleBoard.org Debian Image 2015-11-29 Jan 14 14:35:30 shouldn't it be unuseful on a single core cpu? Jan 14 14:35:37 am i missing something? Jan 14 14:37:51 It's probably just coming via the debian defaults Jan 14 14:38:33 yep. safe to remove it, then Jan 14 14:38:43 Should be Jan 14 14:38:59 There's a few of those gems in debian ;) Jan 14 14:39:18 I think my current favourite is that you need mawk to run the PostSetup scripts of a ton of things, even when mawk isn't in the base Jan 14 14:39:50 Or perhaps the fact that OpenSSH pulls in perl so it can use perl to mangle the sshd_config ... Jan 14 14:40:01 ( yeah, that one is good ) Jan 14 14:57:36 heh, I've reached the point where boot time is dominated by u-boot Jan 14 14:58:01 I really ought to kill that 2-second delay there at least Jan 14 14:58:31 what are you down to, zmatt .. I need to squash my wand boot time down... Jan 14 15:00:16 depends a bit on when you consider the system booted, but after Jan 14 15:00:31 [ 3.834756] systemd[1]: Started User application.

My boot is "fast enough" right now ;) Jan 14 15:14:11 yeah ditto Jan 14 15:14:20 plus the main time is now taken by u-boot Jan 14 15:14:34 our VPN online service is the major killer. Jan 14 15:14:46 I wonder how fast a decent driver could load the data from eMMC Jan 14 15:14:47 establishing VPN service and going to ping over it Jan 14 15:15:29 for time till net up, the PHY reset is currently the biggest problem Jan 14 15:15:36 resets I should say, u-boot does one too Jan 14 15:15:56 a VPN service *could* be near-instantaneous with a decent protocol Jan 14 15:15:56 Have you documented your work here? I'd be interested in looking at it Jan 14 15:16:04 "decent" Jan 14 15:16:15 We're on networks that filter outgoing traffic hard enough that we can't run Ntp Jan 14 15:16:31 -.- Jan 14 15:16:38 Needing to run VPN over TLS wrapped at port 443 just to escape enough to get connectivity Jan 14 15:17:04 Many times we've had service outages because someone plugged some hardware into the plug, got the mac lock, then returned our hardware and it was locked out Jan 14 15:17:08 I'm reminded of a friend who briefly worked somewhere where they didn't allow internet access, but did have email Jan 14 15:17:14 so yet made an IP-over-email tunnel Jan 14 15:17:15 Port security is awesome, if it'd have been correctly configured Jan 14 15:17:18 *so he Jan 14 15:17:23 Oh my fucking... Jan 14 15:17:30 Well you can tunnel everything over smtp Jan 14 15:17:44 And if it allows imap you can just wrap it neatly Jan 14 15:18:05 it probably just allowed email via local servers Jan 14 15:18:21 there's IP-over-DNS too, great for internet hotspots Jan 14 15:18:53 Mmmmm Jan 14 15:19:18 Unless you have the DNS from that fucking 3G modem we ended up with Jan 14 15:19:32 and no I haven't documented my work, it's just been mostly going over things and asking "do I really need this?" Jan 14 15:19:36 It'd hijack and rewrite all DNS responses to point at itself if it got an SMS sent to it Jan 14 15:22:51 ... Jan 14 15:23:24 It also didn't rewrite cache /TTL values. That's awesome, isn't it? Jan 14 15:23:32 "shit died funnily" Jan 14 15:23:52 It's a fairly beefy system on that usb stick too Jan 14 15:24:07 I really love the description of this driver: Jan 14 15:24:09 runs a little mips, 128 megs flash, mounted r/w, with telnet allowing root access Jan 14 15:24:18 CONFIG_IFB: "This is an intermediate driver that allows sharing of resources." Jan 14 15:24:22 Hah Jan 14 15:25:04 ah, you mean it was part of internet census 2005 ? ;) Jan 14 15:25:16 eh Jan 14 15:25:18 2012 Jan 14 15:25:29 could have been, but probably not. Most mobile vendors have CGN these days Jan 14 15:25:52 With the current billing levels, people don't really want incoming traffic on their mobile devices Jan 14 15:26:10 Our M2M thing gives us several Megabytes per month. A whole wooping 2 of them. Jan 14 15:26:34 I really can't get firmware upgrades out over that <.< Jan 14 15:28:08 joy Jan 14 15:28:28 I haven't bandwidth optimized Jan 14 15:28:38 I have to do that for the future Jan 14 15:28:39 Which stings Jan 14 15:28:51 Means I have to redesign a fair amount of stuff :-<> Jan 14 15:29:06 ok, time to do battle again with ASoC and see if I can convince the kernel to just fucking config mcasp in a prescribed manner and make the tdm streams available Jan 14 15:29:23 oh? Best of luck. Jan 14 15:29:41 I've been told I won't be needing the GUI part of our stack soon, which means I can rip out a toooon of stuff ;) Jan 14 15:29:45 Headless future, here I come! Jan 14 15:30:09 yeah most beagles here are headless too Jan 14 15:30:23 I've also had CONFIG_USB=n for a while Jan 14 15:31:29 Can't get away with that.. Jan 14 15:31:57 me neither unfortunately Jan 14 15:32:09 I want a BBB with 2 ethernet ports and a ton of rs232+rs485 connectors Jan 14 15:32:40 2 gigabit ports preferably Jan 14 15:32:41 But until I can get that, and a floating rainbow castle made of gold, I'll have to suffice with a lot of usb=>serial Jan 14 15:33:21 And not an on-board switch interface with 3 ports on it Jan 14 15:33:30 Because I've started to hate those things. Jan 14 15:33:33 zmatt: your personal interpretations (re: "not exactly what it says") and unwanted/ill-directed criticisms (re: bad dram test on e2e) are irritating. i think it would be more fruitful to forego such comments and try to interpret what others write with a goal of understanding the point instead of criticising. Jan 14 15:34:47 thank you for the clarification. Jan 14 15:37:49 yates: well, when posting a bad dram test it is imho worth noting that it is one. of course your reply was also a perfectly valid one, but I can't smell that from a distance Jan 14 15:40:37 but sorry if I offended you, I didn't mean to. I do however tend to be fairly direct in feedback, but one shouldn't take that too personal Jan 14 15:42:10 noted. Jan 14 15:45:37 however (perhaps to gild the lilly), my e2e post was about the dabort exception. that was clear. i don't recall stating anywhere that this was a good test, or that that was the only test i was intending to perform. Jan 14 15:46:08 btw, the test is written and running well now. Jan 14 15:46:41 still, no need to take offense in a short remark about it Jan 14 15:47:10 the offense is very minor, agreed. however imho it was worth noting... Jan 14 15:47:14 i have an all 5's, all a's, all f's, and prng Jan 14 15:48:34 ...and the board works... Jan 14 15:48:36 yay! Jan 14 15:48:40 \o/ Jan 14 15:50:02 please education me (i couldn't find it in a quick google): what is the meaning of "\o/"? Jan 14 15:50:33 s/education/educate/ Jan 14 15:50:35 (sheesh) Jan 14 15:51:29 \o/ Hands in the air celebrating :) Jan 14 15:51:38 | Jan 14 15:51:48 ha ha! Jan 14 15:51:48 /\ Jan 14 15:52:12 definitely not to be confused with /o\ Jan 14 15:52:14 or doing jumping jacks? Jan 14 15:52:25 what is "/o\"? Jan 14 15:52:37 (which is best read as "oh no") Jan 14 15:52:39 i need an emotican dictionary. Jan 14 15:52:42 give op to backslash ;) Jan 14 15:52:44 emoticon. Jan 14 15:52:54 /o \ ; o, command not found Jan 14 15:52:57 oh i see, hands on head? Jan 14 15:53:02 or \, no such user ;) Jan 14 16:56:44 ok, fuck the kernel, this shit is totally inpenetrable... time to ditch another driver and Do It In Userspace™ Jan 14 17:03:37 ha ha Jan 14 17:04:03 oh no! not DIIU?!?! Jan 14 17:08:48 µ Jan 14 17:15:03 i can't imagine it would, since the processor doesn't know what PMIC is being used, but does the ROM code attempt to set any registers on the tps65217 over the i2c on boot? Jan 14 17:17:00 the am335x, that is. Jan 14 17:17:40 it looks like the 1.1V regulator is outputting 3.3V on our board and we are wondering if it got set over I2C somehow. Jan 14 17:18:07 the DCDC2 voltage, specifically. Jan 14 17:21:44 uboot does some stuff I -think- then possibly the kernel .. should be in board configs .. Jan 14 17:22:23 that's a possibility. thanks verem Jan 14 17:22:35 veremit: Jan 14 17:28:15 np Jan 14 17:41:09 hello all Jan 14 17:43:44 ship date was said to be moved to december 15th. any news of an approx ship date now? Jan 14 17:49:44 woot hey Amynka Jan 14 17:49:54 veremit: hey :P Jan 14 17:50:00 ltns :D lol Jan 14 17:50:19 indeed :D Jan 14 18:55:03 hey, in my .dts file.. under "compatability", if i'm using a beaglebone green and the cape is compatible with black, is that sufficient enough? Jan 14 18:55:22 I still cannot for the life of me apply a custom DTO to my board to change pinouts Jan 14 19:23:17 Hi I deleted all files from BBB eMMC is there a way to restore it? Jan 14 19:24:53 doubtful Jan 14 19:25:09 maybe with extremely expensive forensics equipment... Jan 14 19:29:57 Hey, is anyone familiar with the "compatible" field in a .dts file? I'm trying to apply a custom overlay and I feel like there is something wrong with the compatibility given that dmesg is giving me this Jan 14 19:30:14 [ 820.596818] bone-capemgr bone_capemgr.9: slot #7: Incompatible with baseboard for 'libpruio' [ 820.605916] bone-capemgr bone_capemgr.9: slot #7: Failed verification Jan 14 19:30:28 (libpruio is the cape I am trying to load) Jan 14 19:30:52 I am using a beaglebone green instead of black.. Jan 14 19:31:02 would there be any differences causing a compatibility error? Jan 14 19:54:38 what does "NANDI2C" mean in the boot mode table (26-7) of the am335x trm? Jan 14 19:55:55 nm Jan 14 19:56:56 in the case of a NANDI2C boot, does the rom code just read the i2c, or does it write? Jan 14 19:57:57 again, we're troubleshooting reasons why our pmic dcdc2 regulator is going to 3.3V instead of 1.1V, which is possible if an i2c is written Jan 14 21:35:19 Where is the memory defined in DT for BBB? From what I can tell the memory map is inherited from am335x-bone-common.dsi which has 256MB, so that value will have to be overwritten right? I mean it does have 512 MB? Jan 14 21:43:19 Never mind, I found it in the source, IE /proc/device-tree. Jan 14 22:16:35 Hey guys, does anyone have any experience with DTO compatibility issues? Jan 14 22:53:28 hi guys Jan 14 22:55:25 i'd like to know whether it is possible to use the second i2c bus on the beagle bone black? I2C2 to have a /dev/i2c-2 device Jan 14 22:55:36 or is this i2c bus already used for something else? Jan 14 23:28:41 derRichard: it looks from the schematic like i2c2 is unused. Jan 14 23:31:10 what ports or does the BBB need to allow in / out through iptables firewall for a USB connection to allow SSH? Jan 14 23:32:00 poffs: SSH is port 22, tcp Jan 14 23:32:34 yeah but I need to allow my system to make DHCP connections, etc, to beaglebone Jan 14 23:35:20 you want to use a beagle bone as a DHCP server? Jan 14 23:35:23 yates: thx. :-( Jan 14 23:35:58 Ah, right... DHCP is port 68, as I recall Jan 14 23:36:07 (tcp and udp) Jan 14 23:36:14 GenTooMan, if you connect to it by USB, you get IP 192.168.7.3, the BBB gets 192.168.7.2 and 192.168.7.1 Jan 15 01:49:17 yates: it only reads. also, ouch! 3.3V on vdd_mpu ? that sounds like a fast and easy route to fry the chip Jan 15 01:50:57 you didn't accidently get a tps65217a instead of tps65217c or d ? Jan 15 02:10:36 Hi guys, I have been thinking of purchasing the BB green from seeed, but i've noticed that it doesn't have a barrel power input. does that mean I can't porvide enough power to USB wifi dongles? Jan 15 02:17:59 Anybody? Jan 15 02:28:09 BB-Green: yes, or you can add external power @5V via the P9 expansion header Jan 15 02:29:11 Does that require a seperate cape, or do I just need to strip a 5V power supply? Jan 15 02:30:26 BB-Green: see here http://www.seeedstudio.com/wiki/images/0/0f/BBG_SRM_V1a_20151009.pdf Jan 15 02:30:36 BB-Green: search for P9 Jan 15 02:34:32 OK So if I understand correctly, P9 is the second row of 23 pins on the board. to power the board through p9, do I just plug in +VDC to one side, and GND to the other? the literature is not very clear on this matter. Jan 15 02:44:38 well, sadly i don't have a Green. My recommendation would be to read the SRM section a dozen times. That's what i do. Jan 15 02:45:10 Haha ok it seems do-able! Jan 15 02:53:36 So it says pins 5 and 6 are for VDD 5V from an external supply, but it doesn't specify which one is positive or negative **** ENDING LOGGING AT Fri Jan 15 02:59:59 2016
