**** BEGIN LOGGING AT Sat Mar 10 03:00:03 2018 Mar 10 03:06:36 scrap Android. I quit life for now. Back to the Motor Bridge Cape. Mar 10 03:08:28 I have nary touched android I understand it can be most acrimonious to utilize. Mar 10 03:09:08 I saw one UART functionality only. I am more into making things move. Mar 10 03:09:57 That's right you want the killer lawn mower. I mean the robot to fight the lawn. Mar 10 03:10:18 I fought the lawn, the lawn won... Mar 10 03:12:02 Yep. Mar 10 03:12:04 I got it too. Mar 10 03:12:15 You should see my new moves w/ that small bot Mar 10 03:12:31 I can go in a sin wave form now. Mar 10 03:12:49 so... Mar 10 03:51:28 that's it you can use it to make crop circles in your neighbors yard if they forget to do there lawn. Mar 10 03:53:56 However it's a bit early to do that. Oh well. Mar 10 03:54:01 Yea boy! Mar 10 03:54:10 I am in the south. Yards been done mowed many times. Mar 10 03:54:27 Tis the season. Mar 10 03:54:43 Ah I'm freezing cold and I have no lawn to butcher as well. Mar 10 03:54:52 I mean mow. :D Mar 10 03:55:30 Oh. Too bad. I heard about that Nor' Easter. Mar 10 03:55:34 Or whatever. Mar 10 03:55:41 Still making a robot and calling it Edward scissor hands has a certain appeal to it. Mar 10 03:56:09 Bots are fun and takes tons of time. Mar 10 03:57:07 I am trying to make a bot listen to my commands once and perform everything on my yard. Mar 10 03:57:32 So, this mower will just cut the grass in a specified order and then stop. Mar 10 03:57:48 No recharge and no running after it once it is done. Mar 10 03:58:11 ... Mar 10 03:58:36 Hey man...right now, this darn electromechanical mower goes and does what is commanded but then takes off still. Mar 10 03:59:04 I have to make a stop example in the software. "import time" crap. Mar 10 04:00:04 so perhaps your next program is to set the mower to run a while then stop whatever it's doing when it reaches a time? Mar 10 04:00:29 Yea. Basically or just run the route and then create the stopping mechanism in the softwaer. Mar 10 04:00:48 so, left right left and then stop. Mar 10 04:01:13 I might make it do other things later but I have to make sure it stays in the yard. Mar 10 04:01:52 Not chase the neighbors dog? Mar 10 04:02:31 Basically. The damn thing does not have a stopping point right now. So, when it is done doing what I told it to do, the damn thing goes straight and keeps going. Mar 10 04:03:18 ... Mar 10 04:03:30 Did you see that burger flipping robot in CA? Mar 10 04:03:39 It even adds cheese. Mar 10 04:05:40 Cheese! Mar 10 04:10:55 Wait it adds sleeze? Mar 10 04:13:24 Maybe...the burgers look weak. They need to add some meat. Mar 10 04:27:44 so the burgers are just cheese then? Mar 10 04:30:02 No...but Python Projects is an interesting book about _______. It has info. about other languages as well. Mar 10 04:30:27 You can set your file system up via Python to make csv, blah, and blah too. Mar 10 04:31:44 csv is handy because it's easily imported to a number of tools Mar 10 04:32:01 Yep. I see csv cannot be handled in UniCode. Mar 10 04:32:12 You need a separate library. Mar 10 04:32:46 why not use pythons built in CSV tool? Mar 10 04:33:00 Let me read that again. Mar 10 04:33:33 csv has no Unicode input. Mar 10 04:33:48 You would need another library outside of csv. Mar 10 04:34:08 ds2: you around? I got chroot to work with a debian bootstrapped image on Android :) Mar 10 04:34:46 but some reason apt-get can't resolve any hostname Mar 10 04:34:51 ping can resolve, but apt-get can't Mar 10 04:35:39 maybe there is no root folder or sudo folder? Mar 10 04:36:13 do not mind me. Mar 10 04:36:44 the question is do you need unicode at all? Mar 10 04:37:18 I am not sure. Mar 10 04:37:41 But if you did, you would need a new library to handle the calls. Mar 10 04:37:45 you could use the resolved ip directly with apt get no? Mar 10 04:37:57 I've done that before. Mar 10 04:38:17 What? Used some other library w/ csv for Unicode input? Mar 10 04:39:42 GenTooMan: Tried that already, it throws other errors "Permission denied" etc Mar 10 04:39:59 There's probably some selinux bullshit going on Mar 10 04:41:24 ds2: I'll show you what I got tomorrow... Mar 10 04:46:16 just convert unicode to ascii :D Mar 10 04:46:40 then convert output to unicode done! Mar 10 04:46:59 night all. Mar 10 04:49:36 Later. Mar 10 04:49:47 I am not going to do it at all. Mar 10 04:49:52 I was just reading. Mar 10 04:50:19 I thought it was an interesting take on things, though. Mar 10 04:59:38 I use CSV a lot with Python currently I am logging 40 voltage inputs from 4 different devices that have timers on them using python. Mar 10 05:03:12 Aw! Mar 10 05:47:41 uhh, python's csv module supports unicode just fine Mar 10 05:48:31 https://docs.python.org/3/library/csv.html search for "encoding" Mar 10 06:16:06 old book = old info. Mar 10 06:39:46 joel_1? Mar 10 07:16:42 hello can anybody help me to detect the number in an image using python for beaglebone Mar 10 07:35:07 Hi: I am new to BBB. I am trying to srtup eclipse c++ for the pasr 2 weeks. Question, which toolchain and gnu make should i use, i am usng win7 pro as a host Mar 10 07:36:01 Bnew: that will largely depend on what OS you are running on the BBB Mar 10 07:36:15 as toolchain/headers need to match that Mar 10 07:36:41 I will go for debian or ubunru Mar 10 07:37:09 then use the appropriate toolchains for debian OR ubuntu Mar 10 07:39:42 Any suggestion? Mar 10 07:42:07 your target is so vague that its simply impossible to suggest anything Mar 10 07:43:03 maybe you'll understand it in windows terms "I'll maybe target Windows Vista or maybe Windows 98SE, but yeah, tell me which VisualStudio will do that" Mar 10 07:44:42 Pls bear with me, i am quite new to this, may i know what do you mean by target? Do you meant by hardware? If yes, it will be bb black Mar 10 07:45:42 no, SOFTWARE Mar 10 07:46:13 I am not using visual studio but Eclipse c++ Mar 10 07:46:40 if you run a release of ubuntu on the BBB then you need a toolchain that MATCHES THAT EXACT RELEASE OF UBUNTU Mar 10 07:46:53 if you run a release of debian on the BBB then you need a toolchain that MATCHES THAT EXACT RELEASE OF DEBIAN Mar 10 07:49:29 Ok. I will do some research about this. But base on your experience, ifor each version, which toolchain will you suggest? Gnu Arm ? Mar 10 07:50:17 42 Mar 10 07:54:36 Pardon me, what is 42? Mar 10 08:51:21 tbr: breathe Mar 10 08:55:35 zmatt: rumor has it I'm doing that, else I'd not be around. ;-) Mar 10 08:56:15 zmatt: actually got distracted by this pesky reallife, wanted to ask him what he's trying to achieve outside of this context, but oh well… Mar 10 09:41:15 hehe Mar 10 17:03:55 hi! Mar 10 17:04:37 has anyone managed to build a full sd card with buildoot? Mar 10 17:04:54 I cannot find BeagleBone BLUE on the official Buildroot repository Mar 10 17:50:03 cyril__: you should be able to just target the BBB instead Mar 10 17:50:15 cyril__: if you need it, adjust the DTB Mar 10 17:50:30 or rather DTS Mar 10 17:54:49 my problem is probably more related to u-boot config, how to see if the device boots correctly and how the partition table looks like Mar 10 17:55:45 because I only have a serial intergace trought /dev/ttyACM0 available only if linux boots correctly Mar 10 17:56:06 interface* Mar 10 17:56:31 through* Mar 10 17:57:07 this tutorial works like a charm: https://eewiki.net/display/linuxonarm/BeagleBone+Blue#BeagleBoneBlue-Debian9 Mar 10 17:57:10 erm, yeah, if you want to play low level, then debug UART access is an absolute MUST Mar 10 17:57:19 but this is for a Ubuntu or Debian rootfs Mar 10 17:58:03 I is a standard access on most board I used but I cannot figure out how to enable it on the BeagleBone Blue Mar 10 17:58:27 I access usigne picocom Mar 10 17:58:29 you attach a USB2serial (3.3V) adapter to it Mar 10 18:00:44 hi Mar 10 18:00:51 apparently that UART is on one of the JST connectors Mar 10 18:01:08 hi Mar 10 18:01:15 that kind of adapter? http://www.dummies.com/computers/beaglebone/how-to-connect-the-beaglebone-black-via-serial-over-usb/ Mar 10 18:01:18 please ,how can solve this error Energia: 1.6.10E18 (Windows 8.1), Board: "LaunchPad (Tiva C) w/ tm4c123 (80MHz)" Board EK-TM4C123GXL (platform tivac, package energia) is unknown Error compiling for board LaunchPad (Tiva C) w/ tm4c123 (80MHz). This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. Mar 10 18:01:40 mostafa: wrong channel Mar 10 18:01:58 cyril__: yes, but you'll need to interface one of the JST connectors Mar 10 18:01:59 mostafa: when you do get to the right channel, tell them they messed up the link on their site Mar 10 18:02:26 ok ,think Mar 10 18:05:04 do you have any example of product that works on it? Mar 10 18:06:33 any 3.3V USB2serial cable will work. You will need to get yourself the right JST connector though Mar 10 18:06:54 * tbr still finds the lack of bbblue SRM annoying Mar 10 18:08:20 https://github.com/beagleboard/beaglebone-blue/wiki/Accessories#UART_I2C_CAN_Quadrature_encoders_PWR Mar 10 18:08:25 apparently it's JST-SH Mar 10 18:08:32 4-pin Mar 10 18:08:57 yep Mar 10 18:09:17 I think I have one at my club Mar 10 18:09:24 thanks :) Mar 10 18:10:31 np :) Mar 10 18:20:20 tbr: Hey tbr. Can you explain to me what bufferClass API does? Mar 10 18:20:57 I know its possible to use the same shared memory in RAM Mar 10 18:21:22 btw, I am talking about SGX 530 GPU Mar 10 18:21:32 In BBBlack Mar 10 18:21:51 Anyone else please comment as well Mar 10 18:21:56 you're talking about the old drivers? Mar 10 18:22:30 Are there any new drivers? I didn't get that... Mar 10 18:22:32 I vauguely remember seeing "buffer class" in the context of those Mar 10 18:22:43 I was talking about the TI graphics SDK Mar 10 18:23:05 For graphics acceleration Mar 10 18:23:16 yup those are the old drivers Mar 10 18:23:59 Oh so where do I find the newer drivers? Mar 10 18:24:32 I think you can just apt-get install them.. or at least the kernel driver Mar 10 18:24:50 e.g. ti-sgx-ti335x-modules-4.9.82-ti-r102 for kernel 4.9.82-ti-r102 Mar 10 18:25:09 and the documentation is included as well? Mar 10 18:25:19 I'll try that right away Mar 10 18:25:34 lemme see if rcn also packaged the userspace stuff.. but I don't think he did Mar 10 18:27:07 see also last post in https://groups.google.com/forum/#!topic/beagleboard/BEipC_SFjaE Mar 10 18:28:55 I'm not sure how much documentation there is for these specific drivers... applications mostly don't need to care since they just use the OpenGL ES 2 api Mar 10 18:29:37 Oh. Mar 10 18:30:03 So do you know anything about the GPU offload project from GSoC Mar 10 18:30:13 never heard of it Mar 10 18:31:01 Also how powerful can the GPU be said to be... @1.6 GFLOPs Mar 10 18:31:41 Like can you tell me this can run some 200- era game or some idea... Mar 10 18:32:41 I have no idea. I can tell you that gaming will definitely not have been even remotely a consideration in the design choices of this SoC Mar 10 18:33:08 the main purpose of the gpu is to support somewhat slick looking user interfaces, and I think android requires one Mar 10 18:33:48 Oh I see. How about media decode? I heard its software based... Mar 10 18:34:18 no media acceleration Mar 10 18:34:36 And also can the NEON FPU be used to offload tasks to it as well? I read somewhere on net it can be used for programming.... Mar 10 18:34:39 the AM335x is focussed on automotive and industrial control applications Mar 10 18:34:51 neon is part of the cpu instruction set Mar 10 18:35:13 it's pretty decent if software is suitably optimized for it Mar 10 20:31:32 ds2: here's strace socket calls on apt-get: Mar 10 20:31:37 [pid 4002] socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = -1 EACCES (Permission denied) socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = 3 Mar 10 20:31:52 I disabled selinux but still no luck. Mar 10 20:32:05 Did the following: Mar 10 20:32:08 adb shell su 0 setenforce 0 setenforce: SELinux is disabled Mar 10 20:32:27 err, the "setenforce: .." bit is the output on the next line Mar 10 20:42:05 hmmm Mar 10 20:42:18 what does strace say? Mar 10 20:52:01 wait, 'adb' suggests it's android, 'apt-get' suggests it's debian, and selinux suggests it's neither ? Mar 10 20:53:01 is the kernel recent enough to support SOCK_CLOEXEC and SOCK_NONBLOCK ? Mar 10 20:53:22 wait what? IPPROTO_IP ? Mar 10 20:53:25 raw ip socket? Mar 10 20:53:41 why on earth would apt try to open one? Mar 10 20:53:57 that makes zero sense Mar 10 21:06:34 enigmatic Mar 10 21:17:38 android nowadays actually uses selinux. at least AOSP Mar 10 21:20:03 and of course there's adb for debian ;) Mar 10 21:20:05 oh what... I just scrolled back, but apparently this is about debian in a chroot on android Mar 10 21:20:11 why oh god why? Mar 10 21:21:09 but ok, didn't know it used selinux Mar 10 21:21:27 it's evidently not the issue here anyway Mar 10 21:22:43 anyway, a real paste to some pastebin would probably be clearer Mar 10 21:22:59 than one-line fragments posted here Mar 10 21:25:49 man 7 ip says AF_INET, SOCK_DGRAM and IPPROTO_IP are not a valid combination Mar 10 21:26:22 if you really want a raw ip socket, AF_INET, SOCK_RAW, IPPROTO_IP is the right formula Mar 10 21:26:46 so the EACCESS is sort of expected, I'd says ;) Mar 10 21:27:02 yeah it looks all sorts of weird Mar 10 21:30:44 oh what, IPPROTO_IP acts like a wildcard Mar 10 21:30:52 so SOCK_DGRAM, IPPROTO_IP is actually udp Mar 10 21:30:56 ah Mar 10 21:30:58 ok Mar 10 21:31:08 but written in a bizarre way Mar 10 21:31:10 then, that is likely the resolver socket Mar 10 21:34:58 in that case, hard to say what's going on without more info Mar 10 21:35:44 but the person with this issue seems to like the hit-and-run way of asking questions Mar 11 02:14:10 <<<< first C++ program down pat. Thank you...no applause. Thank you. Mar 11 02:14:46 !!!To That Place!!! Mar 11 02:14:49 BBB Mar 11 02:52:15 The software was easier than the IDE. Damn Eclipse ruining everyones' lives. **** ENDING LOGGING AT Sun Mar 11 03:00:02 2018
