**** BEGIN LOGGING AT Fri Mar 24 03:00:01 2017 Mar 24 04:15:29 Hi there...I was a GSoC student. Mar 24 04:16:25 Is there any chance to become a mentor for BeagleBoard this year? Mar 24 05:28:33 Hi, my name Mar 24 05:30:23 Hi, my name is Rishabh Agrahari, I have been reading BBB GSoC ideas page, I am interested in "BeagleBone Sonic Anemometer / Basic Weather Station", I would like to get in touch with its mentor. Mar 24 06:38:03 Hey!! Mar 24 06:38:07 m_w: there? Mar 24 08:41:13 hi Mar 24 11:03:40 nerdboy: Howdy!! Mar 24 11:03:51 I had a look at the cubesat project Mar 24 11:04:04 nerdboy: I am interested to do it. :) Mar 24 11:50:36 jic23b: any idea about the cubesat project? Mar 24 13:20:46 Kiran4399 don't know much about it. Been stupidly busy recently so not doing much more than keep an eye on discussions here... Mar 24 15:11:51 nerdboy: where are you ???? Mar 24 15:45:13 hey kiran4399 Mar 24 15:45:59 m_w: I am interested in the cubesat project. Mar 24 15:46:08 okay Mar 24 15:46:22 wait for nerdboy to show up Mar 24 15:46:34 m_w: do you have any idea on that? Mar 24 15:46:48 m_w: I basically want to integrate blue with that.. Mar 24 15:46:56 kiran4399: I know very little about it Mar 24 15:47:06 hmm.. Mar 24 15:47:42 nerdboy: ping ping! Mar 24 15:48:24 nerdboy might be getting overloaded with students this summer Mar 24 15:48:35 he posted a bunch of ideas Mar 24 15:49:04 m_w: are you posting any ideas involving blue? Mar 24 15:49:24 m_w: I am confused in what to do.. Mar 24 15:49:41 m_w: I am not so much interested in so much deep hardware stuff.. Mar 24 15:49:58 m_w: want to do some development of high level things.. Mar 24 16:00:51 m_w: Mar 24 16:15:03 kiran4399: well what do you think would be a good project for the blue? Mar 24 16:15:40 m_w: I want to port some robotics application on the blue Mar 24 16:16:01 m_w: which can be used in accordance with the hardware present on the blue Mar 24 16:16:30 kiran4399: anything specific software wise? Mar 24 16:16:39 m_w: not much. Mar 24 16:16:44 m_w: do you have some? Mar 24 16:16:50 m_w: ideas? Mar 24 16:16:53 :( Mar 24 16:16:56 I think that ROS is somewhat supported already Mar 24 16:17:02 yeah Mar 24 16:17:13 I thought of ardupilot.. but even that is supported. Mar 24 16:17:20 there is a need to create some kernel drivers Mar 24 16:17:29 for ecap and eqep Mar 24 16:17:56 but I think some of that is already in the works Mar 24 16:18:44 I have a blue in trade for helping mainline things Mar 24 16:18:50 oh. Mar 24 16:18:57 m_w: what are those? Mar 24 16:19:38 the above mentioned drivers, devicetree Mar 24 16:21:13 I think that you would need to be very comfortable with the process of kernel driver development Mar 24 16:21:37 and willing to properly work with the upstream mailing lists Mar 24 16:23:02 m_w: yeah.. I have sort of done that before. Mar 24 16:23:35 m_w: are you willing to propose kernel driver development for blue for this years gsoc? Mar 24 16:23:43 m_w: it's not there on the ideas list though. Mar 24 16:27:42 I will consider it Mar 24 16:27:58 how many days left for the submission? Mar 24 16:28:25 11-12 days Mar 24 16:28:28 m_w:^^ Mar 24 16:28:46 and remember the list is just seed ideas, you can propose anything you wish to work on Mar 24 16:39:02 m_w: my proposal http://elinux.org/BeagleBoard/GSoC/node-beaglebone-boot is almost complete, if you have time, can you please review it and give feedback :) Mar 24 16:40:09 ravikp7: hasn't changed much since the last time I looked at it Mar 24 16:40:38 m_w: yeah, under the hood minor additions Mar 24 16:41:22 I see you paraprased what I said :) Mar 24 16:41:43 yeah :) Mar 24 16:41:57 turns out uniflash works on linux Mar 24 16:42:24 I'll look into it and correct it Mar 24 16:42:30 looks like they have a cloud version too Mar 24 16:42:39 https://dev.ti.com/ Mar 24 16:42:52 not sure how well it works Mar 24 16:43:09 you will need to create an account to try it Mar 24 16:43:47 I need to look before speaking because it has changed a lot since I last used it Mar 24 16:43:56 I don't have a hardware, so can't test it Mar 24 16:43:56 http://processors.wiki.ti.com/index.php/Category:CCS_UniFlash Mar 24 16:44:41 it says toward the bottom that sitara needs to older version Mar 24 16:44:43 ah Mar 24 16:45:11 http://processors.wiki.ti.com/index.php/CCS_UniFlash_v3.4.1_Release_Notes#Installation_Instructions Mar 24 16:45:26 the older version "supports" windows and linux Mar 24 16:45:31 no mac though Mar 24 16:45:33 m_w: please express your views about benefits of Sonic Anemometer Mar 24 16:45:53 and please review this page if possible Mar 24 16:45:59 kiran4399: cubesat from a couple years ago is mainly a python 9250 spi driver and magnetometer filtering/data fitting Mar 24 16:46:16 hey nerdboy!! Mar 24 16:46:28 http://elinux.org/GSoC2017_sonic_anemometer_proposal Mar 24 16:46:31 thetransformerr: that's looking better... Mar 24 16:46:48 nerdboy: so what would be for this time? Mar 24 16:46:55 nerdboy: Finally you are here!!!!!! Mar 24 16:47:07 what it says Mar 24 16:47:09 nerdboy: integrating ardupilot with beaglesat on blue? Mar 24 16:47:20 thetransformerr: great project for the aspiring weather scientist Mar 24 16:47:21 nerdboy: what do you say? Mar 24 16:47:52 and :).... Mar 24 16:48:13 mavlink navigation using blue/black/green plus a 9250 (or just the ak part) dor data acquisition Mar 24 16:48:41 nerdboy: when you say navigation.. how will it move? Mar 24 16:49:44 initial velocity in low earth oribit Mar 24 16:50:01 nerdboy: did you checked error analysis I added in my wiki... Mar 24 16:50:15 m_w: so it seems uniflash for am335x is only supported for upto windows 8 and linux only, no cloud version too. right? Mar 24 16:50:34 yeah, that's what i menat by "looking better" Mar 24 16:50:43 ^ thetransformerr Mar 24 16:50:46 as you said maths and physics doing on notepad was real fun... but could you help me in further analysis Mar 24 16:50:54 thanks sir.... Mar 24 16:51:08 ravikp7: there appears to be a "web" version Mar 24 16:52:04 think you can do an example using synthetic data? Mar 24 16:54:23 kiran4399: think can you find an example? as in google cubesat orbital parameters Mar 24 16:55:11 these are student projects/ideas... Mar 24 16:57:02 there are a couple of different beagle autopilot implementations Mar 24 16:57:33 but they do use some extra hardware Mar 24 17:00:08 m_w: I registered and downloaded the web version for linux, isn't opening in ubuntu 16.04, seems outdated. I'll update proposal accordingly, Thanks :) Mar 24 17:00:26 ravikp7: good Mar 24 17:01:05 so I wasn't completely wrong about the TI tools Mar 24 17:01:12 phew Mar 24 17:03:21 m_w: how do you find the description and timeline in the proposal? any suggestions regarding that? Mar 24 17:05:03 looks okay, gotten any feedback from jkridner? Mar 24 17:06:25 maybe ellaborate a bit more but otherwise okay Mar 24 17:06:42 no, not yet, he seems busy Mar 24 17:07:23 well he is the mentor for this project, perhaps you can try sending him an email Mar 24 17:07:23 ellaborate more about the integration of server with gui? Mar 24 17:08:42 yeah and about the current state of BBBlfs, maybe link to the repository if there is one Mar 24 17:09:19 I sent him mail on 20, he told me on 21 that he will give feedback today or tommorow, havn't heard from him since then, may be he is busy, so don't want to disturb him again Mar 24 17:09:20 I see there is a link to your pull request Mar 24 17:09:26 yeah Mar 24 17:09:52 well Mar 24 17:10:30 https://erlerobot.github.io/erle_gitbook/en/ <= hard to tell how current this stuff is Mar 24 17:10:49 if he is going to be the mentor you are going to have to ping him and make sure that he has the bandwidth to mentor the project Mar 24 17:11:11 kiran4399: i think you'll need to try figure that out Mar 24 17:11:30 ie, how much is implemented/missing Mar 24 17:12:22 find an erle robotics person and twist it out of them... Mar 24 17:13:08 m_w: hmm, I'll email him again today , thanks :) Mar 24 17:29:54 kiran4399: if it's still not clear or it looks too unfinished then maybe that project isn't viable righ now Mar 24 17:29:58 nerdboy: Mar 24 17:30:34 nerdboy: which project? Mar 24 17:30:43 nerdboy: beaglesat integration? Mar 24 17:32:17 depending on the state of beaglepilot Mar 24 17:33:08 it it's really the pixhawk cape that's currently supported then we need to make sure we can actually get it Mar 24 17:37:33 nerdboy: why don't we use blue? Mar 24 17:38:14 because ardupilot runs on a microcontroller? Mar 24 17:38:55 ardupilot can also be run on blue right? Mar 24 17:39:03 nerdboy: ^^ Mar 24 17:39:09 i don't think there's anything mavlink-y that doesn't need one Mar 24 17:39:31 the cape has an atnega or similar Mar 24 17:40:39 there's a host side for mavlink broadcast/other stuff but the core autopilot firmware needs a separate core Mar 24 17:40:54 i'm gonna say it's too big for pru stuff Mar 24 17:41:35 *separate arduino-ish core with control of the flight stuff Mar 24 17:42:24 in this case there aren't any servos or speed controllers since you don't have any rotors/etc Mar 24 17:43:03 nerdboy: oh.. Mar 24 17:43:16 this cubesat thing is simple Mar 24 17:43:34 like one step above the nexus phone satellite Mar 24 17:45:41 actually you might be able to trim stuff down enough to run a couple of parts on the prus (or even the host side with rt-kernel Mar 24 17:45:52 s/for/or/ Mar 24 17:48:07 i guess the goal isn't specified well enough Mar 24 17:49:02 one approach would be the full beagle/firecape/date-sensors thing Mar 24 17:50:17 it would use more power but (potentially) some movable parts to "manipulate" drag to adjust speed, etc Mar 24 17:51:07 nerdboy:, m_w: Hmm.. ok. another idea I had was to propose something called beagleCV... Mar 24 17:51:26 can we do some basic vision stuff using both the prus? Mar 24 17:51:54 for a board like beaglebone it should be doable right? Mar 24 17:51:55 the other more basic approach for blue/green *without* another controller/cape would be "fixed" ie, no adjustments to drag and just measure stuff Mar 24 17:52:24 depends on what else you'r trying to do Mar 24 17:53:17 minimum is fused position/velocity measurements *and* something else Mar 24 17:53:32 like the previous magnetometer data filtering stuff Mar 24 17:54:17 the mavlink stuff does all that sensor fusion and kalman filtering already Mar 24 17:54:41 so does the location widget in your phone Mar 24 17:55:06 *when set for "high accuracy" using gps and wifi/cell data Mar 24 17:57:35 probably the least-specified project this year... sure you don't want to pick a different one? Mar 24 17:58:40 otherwise it needs more literature research than it seems on the surface... Mar 24 17:58:51 nerdboy: I think I will.. Mar 24 17:59:13 nerdboy: the only think is that I want to work more on the high level software side than the hardware side.. Mar 24 17:59:30 nerdboy: I am out of ideas unfortunately.. :( do you have some? Mar 24 18:00:56 i wasn't suggesting implementing a kalman filter with your ass... Mar 24 18:01:35 that might be an impressive project but donno if it is gsoc applicable ;) Mar 24 18:01:52 there should be plenty of existing software, should be more a matter of integrating and filling in some holes Mar 24 18:02:21 nerdboy: yeah.. exactly.. that's what I mean.. Mar 24 18:02:35 nerdboy: something else which I can do with the blue? Mar 24 18:02:39 * nerdboy assumed begalepilot/other stuff was not so old/sketchy Mar 24 18:03:55 you could propose a camera thing... Mar 24 18:05:01 the real-time vision processing on beagle drone has kinda low performance Mar 24 18:06:31 but there are plenty of other applications for imagery Mar 24 18:06:42 nerdboy: yeah.. Mar 24 18:06:46 that's correct. Mar 24 18:06:59 there's an ndvi cape project Mar 24 18:07:41 Oh.. Mar 24 18:07:45 nerdboy: what is it? Mar 24 18:08:09 stereo images are useful, near-IR and other bands for extracting data Mar 24 18:08:48 Oh.. Mar 24 18:09:10 nerdboy: actually I am looking for vision stuff to integrate with beaglebone because my reserch area is robotic vision Mar 24 18:09:16 nerdboy: can you tell more about it? Mar 24 18:09:25 https://publiclab.org/notes/gpenzo/03-25-2015/ndvi-cape-for-the-beagle-bone Mar 24 18:09:46 i was talking aerial imagery mostly Mar 24 18:10:04 robotics is fine too Mar 24 18:10:16 * nerdboy pokes m_w Mar 24 18:11:25 we found a few papers/other things on vision processing using beagle hardware Mar 24 18:11:52 go do your google-y literature search Mar 24 18:12:11 nerdboy: so what should we implement in this project? Mar 24 18:12:26 nerdboy: some kind of extracting depth from stereo? Mar 24 18:15:35 nerdboy: is that cape available online/ Mar 24 18:15:37 ? Mar 24 18:18:53 nerdboy: seems an interesting project.. I like it.. Mar 24 18:31:16 is there another open stereo to depth extrator out there besides opencv? Mar 24 19:02:39 here is an interesting project: https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2013/08/18/bbb--imaging-with-a-pru-connected-camera Mar 24 19:09:05 * m_w signs off for a little while Mar 24 19:50:24 m_w,nerdboy: there? Mar 24 19:54:04 kinda... Mar 24 19:55:10 nerdboy: i was trying to check the compatibility of ums with emmc Mar 24 19:55:40 since, ums only works with a single block device Mar 24 19:56:39 so , does emmc has only one block? Mar 24 20:04:28 emmc is like an sdcard at the higher level Mar 24 20:05:11 other than that i haven't looked at the details Mar 24 20:08:13 nerdboy: i performed sgdisk command to get info of partitions,sectors Mar 24 20:08:15 http://pastebin.com/Jdi5fCip Mar 24 20:08:30 ^ please have a look at it's output Mar 24 20:10:37 looks like a disk Mar 24 20:11:01 not sure what you're asking... Mar 24 20:27:12 it should just be a block device you can treat like an sdcard interface Mar 24 20:35:29 nerdboy: gotcha! i misunderstood blocks with sectors **** ENDING LOGGING AT Sat Mar 25 03:00:02 2017
