**** BEGIN LOGGING AT Fri Jun 17 02:59:58 2016 Jun 17 03:38:33 * ZeekHuge is working on documentation and Posts stuff. Jun 17 03:40:59 * ZeekHuge 's been working on them since last day, but since its his first ever post, there was some fear/nervousness kind of feeling . Though its gone now. Jun 17 11:29:04 jic23: there? Jun 17 11:34:32 kiran4399 - kind of, in and out a bit today as setting up some test rigs. Jun 17 11:34:58 New toy of the day wafer scale x-ray sensor, got to love the 15x12 cm chips ;) Jun 17 11:35:09 none of these microdevices here ;) Jun 17 11:38:02 back in 5 - need to reboot. Jun 17 11:47:10 jic23: not getting bmp280.. Jun 17 11:47:48 jic23: modprobe bmp280 and plugged in bmp280 in i2c port p9.19 and 20.. Jun 17 11:48:13 jic23: I am able to see bmp280 at 0x76 but when I dmesg.. Jun 17 11:48:32 jic23: probe of 2-0076 failed with error -121 Jun 17 12:15:29 kiran4399 - odd... Jun 17 12:17:08 out of curiosity, when you got the imu working on the break out board, was it on a different i2c bus. Jun 17 12:17:10 ? Jun 17 12:18:32 There is really very little at all in that drivers probe, so I'm wondering if we are looking at something odd about that bus. Jun 17 12:28:18 Also, 121 is EREMOTEIO which is downright odd... Jun 17 12:29:24 well.. I connected to the i2c2 bus for the imu and the pressure sensor.. Jun 17 12:29:26 both.. Jun 17 12:33:31 jic23:^^ Jun 17 12:34:42 going to dig and see what might spit out remoteio error. That one confused me the first time around. Can tell you nothing in IIO or IIO drivers does... Jun 17 12:37:29 hmm. it's coming from i2c bus driver... Jun 17 12:37:58 jic23: OK.. I too will look into that.. Jun 17 12:38:05 jic23: tell me one more thing.. Jun 17 12:38:22 jic23: I applied your patches.. Jun 17 12:38:29 http://lxr.free-electrons.com/source/drivers/i2c/busses/i2c-omap.c#L733 Jun 17 12:38:41 sure, (hopefully not the last one!) Jun 17 12:39:07 jic23: What other additional attributes did you create apart from the already existing ones in the inv_mpu6050 kernel driver... Jun 17 12:39:08 ? Jun 17 12:42:23 none... unless you have the devicetree stuff for the magnetometer - see binding doc changes in those patches for examples. Jun 17 12:51:02 jic23: also.. did you get the dmp stuff working? Jun 17 12:54:53 dmp stuff is completely undocumented (or publicly so anyway) and invensence aren't interested in making it public (we asked a while back). Jun 17 12:55:10 So only way it could be done is if it was reverse engineered from a vendor kernel. Jun 17 12:55:39 Their advice has always been that it doesn't actually make all that much sense in a linux device anyway as all the stuff it is spitting out is better done in userspace. Jun 17 12:56:33 so if you are interested in posting patches to add that stuff or someone else is then we can review it as best as we can without docs... Jun 17 12:57:05 Also, I suspect a good part of this is that they want to be able to change that stuff in new firmwares without having to maintain ABIs etc... Jun 17 13:04:53 Sorry was on phone... actually regoogling the dmp stuff shows they released some stuff... Jun 17 13:16:08 kind of ish as it turns out. + needs a firmware loader... There is a library to access it on bare metal parts which could probably be used to figure it out, but still no documentation of how to actually talk to it. Jun 17 13:19:29 Anyhow, up to anyone interested enough to put together patches to support it. Jun 17 13:26:01 kiran4399 - just reading the license on the demo code that invensense allow you to download from their website... Can see why no one has ever done linux kernel support: Jun 17 13:26:01 take any actions, including combining or distributing the Software with open source software, that would cause the Software or any portion thereof to become subject to the GNU General Public License or any other open source license that imposes any limitation, restriction or condition requiring that the Software combined or distributed with such open source software: Jun 17 13:26:31 Could conceivably do it via a chinese wall I guess, but that's a nasty game to get into without a big corporation and expensive lawyers. Jun 17 13:26:56 So pretty much a non starter unless someone persuades invensense to change their midn. Jun 17 13:27:09 wowsers, nice license :/ Jun 17 13:30:12 quite, there is some MIT licensed stuff in ardiuno libraries but who knows how they pulled that off (or whether they actually did...). Jun 17 13:31:24 I wouldn't be surprised if those were in violation Jun 17 13:32:36 if I were to somehow get explicit permission or a relicensed version to use in an open source library, I would probably mention that in the header of every file Jun 17 13:32:40 I suspect filling in the login for their 'developers corner' with why? 'To work on a linux kernel driver'. Might mean I need to keep well clear of this. Jun 17 13:32:46 quite. Jun 17 13:34:06 particularly when then have the binary firmware from the aforementioned library as a big array in one of the header files... Jun 17 13:34:42 yuck! Jun 17 13:34:56 https://github.com/jrowberg/i2cdevlib/blob/master/Arduino/MPU6050/MPU6050_9Axis_MotionApps41.h# Jun 17 13:35:38 "...and it seems to be volatile memory..." Jun 17 13:35:51 I guess they aren't even sure what they're doinf exactly Jun 17 13:36:25 yup. I think we can see why invensense weren't keen on this going into drivers they don't directly control. Jun 17 13:37:45 interestingly it seems invensense themselves added some DMP stuff to the android library: https://android.googlesource.com/kernel/msm/+/android-msm-hammerhead-3.4-kk-fr2/drivers/staging/iio/imu/inv_mpu Jun 17 13:37:51 driver* Jun 17 13:50:27 alexhiam - might be possible to persuade them to add this stuff... Jun 17 13:51:34 anyhow, might be back later. bye for now. Jun 17 14:01:04 hey bradaf,there? Jun 17 14:01:20 bradfa, ^^ Jun 17 14:07:24 hi chanakya_vc Jun 17 14:08:05 chanakya_vc: regarding your previous questions about DMA, mdp will likely be a good resource for you to ask questions to Jun 17 14:08:31 chanakya_vc: but to start with, don't worry about using DMA, just copy over the bytes to make it work first, then add DMA later when it's worth doing Jun 17 14:08:40 bradfa, I have explored various options including DMA and ioremap Jun 17 14:08:57 I am currently working on an implementation via ioremap Jun 17 14:09:28 *have been exploring various option : ) Jun 17 14:09:30 chanakya_vc: I don't think ioremap and DMA are mutually exclusive, but I'm no expert in these areas Jun 17 14:10:22 Okay I will ask mdp Jun 17 14:11:32 Apart from that I am truly sorry for the committing two things together, bradfa Jun 17 14:12:03 Will be more careful in the future. I can't seem to adhere to the standard practices :( Jun 17 14:12:13 chanakya_vc: I am just giving you guidance, not criticism, don't feel bad about it Jun 17 14:12:54 chanakya_vc: if you could see all the mistakes I make in a day you'd realize I'm no different than you :) Jun 17 14:13:02 chanakya_vc: hello, I'm back from holiday now..but on a call atm Jun 17 14:13:04 chanakya_vc: the best part about software is it's really quick to fix mistakes :) Jun 17 14:13:51 chanakya_vc: and like bradfa says, it's always best to get your code working without DMA first..then enable DMA support next Jun 17 14:14:07 bradfa, Haha. if not for you, I would never learn.But I should try to not repeat my mistakes :P Jun 17 14:14:27 mdp, I have been working on ioremap for now. Jun 17 14:14:50 You don't think that is a good option?mdp Jun 17 14:16:08 mdp, I can mail you all the stuff I seem to have understood till now?Perhaps you could correct me if I do not have the correct understanding of something. Jun 17 14:17:30 yes, please email me..I couldn't keep up while on holiday on the day-to-day happenings Jun 17 14:18:13 bradfa, mdp, Because I did not find much on these on Google either.I have been reading ldd3 and that seem to add to my confusion a little. Jun 17 14:18:34 mdp, I will... Jun 17 14:19:42 mdp, Should I continue to work on ioremap, or should I abandon it? I think I can finish my code today itself and maybe push it on github? Jun 17 14:53:26 chanakya_vc: keep working with ioremap, see how it works out for you Jun 17 14:54:56 bradfa, Also, I can expose a char dev file right? Later I will migrate to the interface that the McSPI driver exposes? Jun 17 14:55:17 chanakya_vc: yes, you can expose a char device in /dev/ to do testing with Jun 17 14:55:27 * chanakya_vc not able to understand McSPI driver at the moment Jun 17 14:55:48 chanakya_vc: mcspi is a very full featured SPI master Jun 17 14:56:20 chanakya_vc: I expect there's also slight differences among actual silicon implementations, which probably doesn't help it be easy to understand Jun 17 14:56:32 Also, bradfa I am a little confused as to how will I compile the driver.It has to be cross compiled right? Jun 17 14:56:39 chanakya_vc: yes Jun 17 14:56:56 chanakya_vc: https://www.kernel.org/doc/Documentation/kbuild/modules.txt Jun 17 14:57:10 Will probably need your help again with the makefile bradfa Jun 17 14:57:24 chanakya_vc: ok, np :) Jun 17 14:57:45 I get confused with makefiles so much. bradfa I wonder when will I master it Jun 17 14:59:04 Okay I am working on completing the driver using ioremap. Should be done by tomorrow. I will inform you and mdp by mail. Jun 17 14:59:29 chanakya_vc: sounds good, thanks! :) Jun 17 15:00:07 chanakya_vc: makefiles can get quite crazy, don't worry, we can work together to make yours as simple as we can and provide good documentation/comments to explain so that others can learn from it Jun 17 15:02:04 bradfa, That sounds great! Are you free later today? Jun 17 15:02:12 mdp^^ Jun 17 15:03:50 chanakya_vc: I'm going to give your pru code a try today. Jun 17 15:04:27 chanakya_vc: not sure yet what my afternoon looks like but if you have questions just ask and I'll see them Jun 17 15:04:43 kiran4399: I thought you already had the pressure sensor working? Jun 17 15:04:51 chanakya_vc: don't worry about all the complexities of make for now..you just need the basics Jun 17 15:06:38 chanakya_vc: it would be great if you push what you have to github for review. Jun 17 15:07:02 mdp, Okay,there are some commits that I haven't done. I will do so. Otherwise you can take a look here:https://github.com/chanakya-vc/PRU-I2C_SPI_master/issues/3 Jun 17 15:07:12 For the plots Jun 17 15:08:50 alexhiam: no.. I was also trying then..that time it was not even showing on the i2c bus.. but now, with the chip on the breakout board. it is showing on the bus but not working.. Jun 17 15:08:51 nice Jun 17 15:08:54 probe failed.. Jun 17 15:09:03 mdp, I have to update the readme too. I will do so tonight. Please give me time till tomorrow. I will update the readme,fix the commits Jun 17 15:09:04 with error 121 Jun 17 15:09:21 kiran4399: bummer! how are you probing it? Jun 17 15:09:38 alexhiam: I just connected the device to i2c2 Jun 17 15:09:46 p9.19 and p9.20 Jun 17 15:10:00 kiran4399: I mean are you using DT? Jun 17 15:10:18 mdp, bradfa suggested some changes that I haven't done. I will do so today. I will update the readme too.Maybe then you could reproduce the result on your end. Jun 17 15:10:29 alexhiam: well. the dt was not working.. but instantiation made showed up the device at 0x76 Jun 17 15:10:39 * chanakya_vc been lazy with commits. Will fix it Jun 17 15:11:20 kiran4399: instantiation? Jun 17 15:11:57 alexhiam: echo bmp280 0x76 > /sys/class/i2c-adapter/i2c-0/new_device Jun 17 15:12:32 and dmesg showed the -121 return after that? Jun 17 15:13:38 yeah.. Jun 17 15:14:00 alexhiam: but I could see the device at 76 Jun 17 15:14:10 with i2cdetect? Jun 17 15:14:46 alexhiam: i2cdetect -r 0 Jun 17 15:15:17 -r 0? Jun 17 15:15:32 yeah.. read probe on i2c-09 Jun 17 15:15:35 *i2c-0 Jun 17 15:15:36 that's /dev/i2c-0, which should be I2C0 with universal-io... Jun 17 15:15:48 or did you disable that? Jun 17 15:16:13 alexhiam: no.. i did not.. Jun 17 15:16:41 what do you get with i2cdetect -r 2 ? Jun 17 15:18:23 wait... sorry.. Jun 17 15:18:34 alexhiam: I got 76 with 2.. Jun 17 15:18:46 alexhiam: I did not get 76 with 0.. Jun 17 15:19:15 kiran4399: ok, try this... Jun 17 15:19:30 first run 'pip install -U serbus' Jun 17 15:20:19 then reboot to make sure the module isn't loaded and try running this python script: http://pastebin.com/0yknnWcy Jun 17 15:21:14 you should hopefully see "value in ID register: 0x58" Jun 17 15:24:14 alexhiam: ok.. looks like I have'nt updated my board for a while.. Jun 17 15:24:30 alexhiam: it is updating and then I'll try the stuff you told me. Jun 17 15:24:44 alexhiam: btw.. what do you think the problem should be? Jun 17 15:25:11 no idea! Jun 17 15:25:49 alexhiam: I am working on the imu apis now. Jun 17 15:25:58 alexhiam: should be finished by tomorrow.. Jun 17 15:26:02 awesome Jun 17 15:26:20 alexhiam: so according to my schedule.. I am still yet to do with adc apis.. Jun 17 15:26:47 alexhiam: but I am planning to ehrpwm.. what do you suggest?? which one should be easier? Jun 17 15:27:08 alexhiam: so that I can show things for mid. Jun 17 15:30:05 hey ! please have a look and let me know if i made any mistake somewhere, working on others too ! Jun 17 15:30:06 http://zeekhuge.github.io/post/working_with_prus_beagleboneblack_introduction_to_prus/ Jun 17 15:31:12 kiran4399: don't the adc and pwm apis already use the drivers? Jun 17 15:31:31 kiran4399: I don't think there's much to be done there Jun 17 15:31:55 kiran4399: I think it would be good to jump into the pru stuff Jun 17 15:34:07 alexhiam: https://github.com/StrawsonDesign/Robotics_Cape_Installer/blob/master/libraries/robotics_cape.c#L931 Jun 17 15:34:22 :( Jun 17 15:34:22 alexhiam: I think the adc api still uses mmap.. Jun 17 15:35:05 well, should be pretty quick to change that Jun 17 15:38:00 alexhiam: can we start the pru after the mid? Jun 17 15:38:32 kiran4399: yeah, that's fine as long as you don't run out of other things to do before then Jun 17 15:38:59 I think a good goal would be to get all the non-pru APIs finished by midterms Jun 17 15:39:21 alexhiam: ok.. Jun 17 15:39:41 kiran4399: I gotta run, be back in a bit Jun 17 15:40:08 alexhiam: umm. ValueError: Unknown format code 'x' for object of type 'str' Jun 17 15:40:16 alexhiam: I am getting this error.. Jun 17 15:40:34 ah, just take out the stuff in the curly braces then Jun 17 15:40:40 alexhiam: but when I am printing the value..it is showing 88 Jun 17 15:41:02 kiran4399: btw, I'm not saying that's what's required to pass midterm, just seems like a good goal. Would be good if you could make a list of what's done and what still needs to happen for the APIs Jun 17 15:41:29 awesome, 88 in hex is 0x58 Jun 17 15:41:36 so it is reading the ID register just fine Jun 17 15:41:44 k, back in a bit Jun 17 15:41:48 alexhiam: yeah...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Jun 17 16:35:00 Kiran4399 that 121 error is no ack on i2c bus. Either not reading right bus for some reason or reading something it shouldn't be such as a wrong register address. Can you add a few printks to the driver to find out which read it is? Jun 17 16:35:41 Or stick a logic analyser on bus and look at last message to be sent... Jun 17 16:43:08 ah, "echo bmp280 0x76 > /sys/class/i2c-adapter/i2c-0/new_device" <- should be i2c-2 Jun 17 16:58:02 cool, looks like the new rpmsg stuff is now on the rcn tree: https://groups.google.com/d/msg/beagleboard/cYHCN3GWw_E/ZJugfuRuBQAJ Jun 17 16:58:55 kiran4399: you said you did "echo bmp280 0x76 > /sys/class/i2c-adapter/i2c-0/new_device" Jun 17 16:59:00 should be i2c-2 though Jun 17 17:00:29 ZeekHuge: did the board arrive? Jun 17 17:00:46 alexhiam: on it.. Jun 17 17:01:06 alexhiam: shall I modprobe? Jun 17 17:01:22 kiran4399: no, that'll probe it Jun 17 17:01:31 I think Jun 17 17:01:44 alexhiam: I got a UU Jun 17 17:01:48 at 76 Jun 17 17:01:53 modprobe won't do anything unless you have it listed in your DT Jun 17 17:02:14 so "echo bmp280 0x76 > /sys/class/i2c-adapter/i2c-2/new_device" should do it Jun 17 17:02:33 but I did not get anything in /sys/bus/iio :( Jun 17 17:02:45 UU? did something else grab it? Jun 17 17:02:46 dmesg? Jun 17 17:03:17 alexhiam: How are you such a genius??? Jun 17 17:03:24 oh right, UU means that, doesn't it Jun 17 17:03:30 alexhiam: It's working!!!!!!!!!!!!!!!!!!!! Jun 17 17:03:36 kiran4399: I'm far from it ;) Jun 17 17:03:43 great Jun 17 17:03:44 alexhiam: ooooooooooooooooooohh.. Jun 17 17:04:28 alexhiam: I got in_temp_input Jun 17 17:05:08 alexhiam: and in_pressure_input Jun 17 17:05:29 how did the bmp's get to be an IIO driver?! Jun 17 17:05:48 it's in: Jun 17 17:05:50 root@beaglebone:/sys/bus/iio/devices/iio:device0# Jun 17 17:06:08 yes but aren't slower changing drivers suppose to be hwmon Jun 17 17:06:26 ds2: jic23 is slowly taking over all of linux Jun 17 17:06:30 don't think the bmp280 is that much faster then the other hmp Jun 17 17:06:33 bmps Jun 17 17:06:47 alexhiam: I guess so... but that contracts a recent discussion ;) Jun 17 17:06:51 (on the list) Jun 17 17:08:29 ds2:Hi ! I asked it yesterday, and it didnt, The given address it to a local relative of mine. Jun 17 17:08:39 *is Jun 17 17:09:02 ZeekHuge: did your relative get it? Jun 17 17:09:40 ZeekHuge: sorry, yesterday was a bit nuts on my end... got yanked into help with several things all of a sudden Jun 17 17:10:06 I asked my relatives yesterday, and no , they didnt got it. Jun 17 17:10:11 ds2: ^ Jun 17 17:10:18 let me track Jun 17 17:13:00 ZeekHuge: is it Friday on your end or is it Saturday now? Jun 17 17:13:42 its Friday, 10:43 PM Jun 17 17:13:47 DOH Jun 17 17:14:21 ZeekHuge: how far is Mumbai from where you are? Jun 17 17:14:28 it seems to be stuck there Jun 17 17:14:55 well, its quite far , about a full day travel. Jun 17 17:18:39 hmmm wonder if that a delivery truck distance or a big truck distance Jun 17 17:28:06 ds2: please have a look on this, sorry its my first post so was kind of nervous and there it took a lot of time, and please let me know if there are mistakes in it. working on others. Jun 17 17:28:12 http://zeekhuge.github.io/post/working_with_prus_beagleboneblack_introduction_to_prus/ Jun 17 17:31:33 ds2: when you said about toggling PRU pins to get data out of ADC, you were saying about the clock ? right ? Jun 17 17:33:27 Hmph irc dropped out. Jun 17 17:33:35 ZeekHuge,ds2 ,There might be a problem with cudtoms Jun 17 17:33:42 customs Jun 17 17:34:37 Ds2 hwmon guys have tightly defined scope as does input. People have started putting humidity sensors in high end servers for environment monitoring but no barometers yet! Jun 17 17:35:40 IIO has a scope of things that are ADC or DAC in some sense and not for PC health monitoring or human input (accelerometers are in the gray area!) Jun 17 17:35:44 ZeekHuge ,Indian Government has made it mandatory for the you to submit a KYC and/or other documents Jun 17 17:37:29 chanakya_vc: package with BBB didnt require anything. Only goog's welcome package neede it. Jun 17 17:37:39 *needed Jun 17 17:38:35 ZeekHuge, Post is awesome Jun 17 17:38:43 Which theme is that? Jun 17 17:39:58 chanakya_vc: customs for india is at Mumbai, not the port? Jun 17 17:40:01 jic23: no servers on planes yet? :D Jun 17 17:40:41 chanakya_vc: its HugoMDL Jun 17 17:40:46 Well ds2 Mumbai is a port Jun 17 17:40:48 :P Jun 17 17:41:10 chanakya_vc: wow...didn't think the capitol is also the main shipping port Jun 17 17:41:29 ds2: Capital is Delhi ! Jun 17 17:41:43 not Mumbai Jun 17 17:41:44 New Delhi to be Pedantic Jun 17 17:41:51 <-- confused by all the names Jun 17 17:41:59 thought Mumbai used to be another name? Jun 17 17:42:13 Bombay Jun 17 17:42:14 Mumbai == Bombay Jun 17 17:42:21 other name ^ Jun 17 17:42:23 ah.. my bad Jun 17 17:43:26 ZeekHuge: check to see if there are lines like /CS, /RD that needs to be toggled/driven for output Jun 17 17:43:43 So Mumbai would be New York city and Delhi is Washington DC,if an analogy were to be made :P Jun 17 17:44:01 it is the name change that threw me off Jun 17 17:45:16 ds2: https://github.com/ZeekHuge/BeagleScope/blob/master/docs/BBB-ADC.pdf Jun 17 17:45:34 these are the only pins ... shown on the left Jun 17 17:45:40 ds2: ^ Jun 17 17:48:52 ds2: so ? is that done now ? Jun 17 17:54:38 let me look Jun 17 17:56:38 ZeekHuge: what's OF? Jun 17 17:57:13 (JP5) Jun 17 17:57:31 its overflow bit. Jun 17 17:58:21 ah... okay... that seems okay then Jun 17 17:58:28 bringing up the datasheet, just a bit Jun 17 17:58:56 if that's the interface - why not get the code to the point where you can clock in patterns? Jun 17 17:59:13 http://cds.linear.com/docs/en/datasheet/223876fa.pdf Jun 17 17:59:16 page 21 Jun 17 17:59:18 say - setup high low patterns on the PRU input (use say a 1K resistor) and just let the code run Jun 17 17:59:47 once you have that you can see if that pattern shows up all the way on the kernel end Jun 17 18:00:13 some ADCs want more but this one looks simple enough Jun 17 18:00:19 so first using the just the PRU ? Jun 17 18:00:30 *just the PRU ? Jun 17 18:00:36 yes Jun 17 18:00:43 the ADC doesn't need to acknowledge anything Jun 17 18:00:50 so you can just run ur code Jun 17 18:01:14 sure, you'll get garbage w/o the ADC unless you put in pull up/down resistors on the Dn lines Jun 17 18:01:19 but it'll test out SW Jun 17 18:02:05 ahh, I will definitely try that, but that looks quite easy to me, after all these examples https://github.com/ZeekHuge/BeagleScope/tree/master/examples Jun 17 18:03:23 I was trying to understand beaglelogic's code as , Abhishek_ once said that it will require trivial changes to do parallel sampling. And then, I will have to look into PRU assembly instructions too. Jun 17 18:06:30 ZeekHuge: your call as to if you want to do more understanding or if you want to try it first Jun 17 18:06:54 it comes down to your preferred style of work and I don't have an issue with either path at the moment Jun 17 18:07:28 but if you do get stuck with the understanding part, ask on this channel... either I or another mentor should see it Jun 17 18:07:31 okay I'll try it. Its the best way to understand :) Jun 17 18:07:44 for sure. Jun 17 18:07:58 ZeekHuge, Your about link is returning nothing Jun 17 18:08:06 Check it out Jun 17 18:08:12 Otherwise amazing site. Jun 17 18:08:23 the big gap between the BeagleLogic code and your code is you need to add clock generation logic Jun 17 18:08:33 chanakya_vc: know that, coz I havent written anything there. ;) Jun 17 18:08:36 interleave that with the main data collection loop Jun 17 18:09:03 ds2: okay. Jun 17 18:17:04 ohh ZeekHuge. :P Jun 17 18:17:08 you should Jun 17 18:17:52 ZeekHuge, Just one question,how do you get images in your posts? Jun 17 18:20:47 chanakya_vc: Thats kind of trade secret ! :P :P haha ! Jun 17 18:21:06 so its markdown. and therefore you can just do it like Jun 17 18:22:14 ![name to the file ](src/to/the/file "Name") Jun 17 18:22:18 example : Jun 17 18:22:44 ![PRU-ICSS](http://elinux.org/images/b/b1/PRUSS.png "PRU-ICSS") Jun 17 18:28:12 Okay ZeekHuge So when you are writing the post, wherever you have to include the photo,you just do this way?Even for the image for the post title? Jun 17 18:28:58 like when you are writing the title after you have done hugo new post/post 1 .md? Jun 17 18:29:28 chanakya_vc: no ! that just embeds the image into your post. Jun 17 18:30:31 That title image thing is in my theme, you will have to edit your theme files for that, like I did to add those beaglescope and github option. Jun 17 18:34:15 Okay got it.... Jun 17 18:34:27 ZeekHuge, Thanks Jun 17 20:07:31 alexhiam, Is there a problem with the latest version of ubuntu. I am helping a friend in flashing it on BBB. And on demsg it gives cdc_ether kevent 12 may have been dropped Jun 17 20:07:58 Any idea why this is happening Jun 17 20:09:03 chanakya_vc: no clue, you'd have to ask the ubuntu folks. Easier to just use the bb.org debian images Jun 17 20:09:29 Seems to be a bug with ubuntu. Jun 17 20:14:56 alexhiam, Both debian 8.4 and ubuntu use systemd as init? Jun 17 20:15:04 ubuntu 16.04? Jun 17 20:15:53 debian does. Not sure about the ubuntu beaglebone images, but ubuntu desktop does Jun 17 21:44:08 newer debian is now systemd-i-fied Jun 17 21:44:45 you can try one of the rcn ubuntu rootfs tarballs, then install some gui stuff Jun 17 21:48:15 actually if you poke around you can find an image too Jun 17 21:48:19 https://rcn-ee.com/rootfs/2016-06-09/microsd/bone-ubuntu-16.04-console-armhf-2016-06-09-2gb.img.xz Jun 17 21:48:41 if you really want ubuntu use that ^^ Jun 17 21:49:19 then you can "apt-get install poopy-gui-desktop" Jun 17 21:49:34 that's my favorite gui Jun 17 21:52:14 aaand we should all send robert a philly and a twelvepack Jun 17 21:52:48 shouldn't us mentors get that too? Jun 17 21:53:14 if i could find what i want easier i would buy more from digikey... Jun 17 21:53:53 alexhiam: can we trade in the box of schwag for beer? Jun 17 21:54:16 I don't think it has a very big trade in value... Jun 17 21:54:21 I guess it depends what beer Jun 17 21:54:26 * nerdboy assumes we all got one Jun 17 21:54:36 *box of TI schwag Jun 17 21:54:59 yup... that water bottle... Jun 17 21:56:55 a nice power power brick with several 2A usb ports would be more helpful Jun 17 21:57:56 newegg had one for about $10 on sale, only got one :/ Jun 17 21:58:48 2xAC plus 2x1A usb and 2x2.4A usb Jun 17 21:59:12 could use a few more of those... Jun 17 21:59:39 * nerdboy wanders into a mtg Jun 17 22:00:50 * nerdboy got side-tracked (again) from making a new sensor test script Jun 17 23:31:19 alexhiam, mdp there? **** ENDING LOGGING AT Sat Jun 18 02:59:58 2016
