**** BEGIN LOGGING AT Sun May 06 03:00:03 2018 May 06 04:15:13 good evening May 06 12:27:52 does anyone have any pointers as to how to compile with ti dsplib on the x15 May 06 12:28:31 Im trying to write a simple demo program and compile using the ti dsplib functions May 06 12:49:45 * zmatt hasn't played with the dsp yet May 06 13:21:00 When powering the BeagleBone by supplying 5V to VDD_5V May 06 13:21:13 Does the power supply need to be able to supply 1A? May 06 13:21:21 Or will 500mA suffice? May 06 14:26:55 depends a bit on what you're doing of course, but I think 500 mA should suffice for basic operation May 06 16:46:58 Hi! Someone with good knowledge in runtime/cycle time on a processor? Please PM :) May 06 17:04:39 don't ask to ask, just ask! May 06 17:05:59 stingz: it is really not clear what you mean by that. also don't ask for a personal assistant, just ask your question (and stick around. there are plenty of knowledgable people here, but often they only occasionally glance at chat) May 06 20:16:37 zmatt: My question is: I have some calculations I am doing in Matlab and another sw - I have timed these ops. I wonder if i can use these runtimes (?) times to make an estimateof how long time it would take running these on a processor? or how good of a processor that is needed for running the ops.. May 06 21:24:27 L298 and the BBB! May 06 21:25:34 https://pastebin.com/GGxYasnp May 06 21:26:13 Can anyone who uses motors and a L298 dual h-bridge see where I may be making a mistake in Python on this software? May 06 21:26:56 The connections work. The BBB is up and running and processing fine. The issue is definitely what I know in Python. May 06 21:26:59 Shoot at will! May 06 21:33:02 just for reference...the software makes my motors slow. I stop the software w/ control-c and the motor turns a normal speed. May 06 21:33:18 Oh! May 06 21:33:36 Can anyone suggest some good books on motor control and Python? May 06 21:33:38 ... May 06 23:25:45 https://pastebin.com/xWQe3dX1 is how I got my motor to turn forward and backward w/out "for i in range(xx, xx):" ideas. May 06 23:26:13 Check it out. This is my newest software from the BBB to a L298 motor driver. May 06 23:26:15 ... May 06 23:26:18 One motor only! May 06 23:40:57 where do I find a cross compiler for beagle bone that uses the http://debian.beagleboard.org/images/bone-debian-9.3-iot-armhf-2018-03-05-4gb.img.xz image May 06 23:54:29 Hey: https://forum.digikey.com/t/beaglebone-blue-getting-started/350 May 06 23:54:32 This may help. May 06 23:54:35 Let me keep looking. May 06 23:56:37 black_13: Did you look? May 06 23:56:43 linaro! May 06 23:56:53 brb May 06 23:59:17 i am looking May 07 00:04:27 Okay. May 07 00:06:43 there is also crosstool-ng May 07 00:08:32 how do match tool chain to image on your board? May 07 00:10:08 Oh... May 07 00:10:28 black_13: I do not think you want to compile on your board. May 07 00:10:42 Compile on the Ubunut or Debian Distro on a 64 bit machine. May 07 00:11:38 ... May 07 00:11:44 it is hard to explain on this chat. May 07 00:11:56 Let me review and try to explain w/ a pastebin. May 07 00:13:34 $ CC=arm-cortex_a8-linux-gnueabihf-gcc \ ./configure --host=arm-cortex_a8-linux-gnueabih May 07 00:14:14 This may make your compilation once completed easy to make it to your target board. May 07 00:14:16 ... May 07 00:14:27 Do not quote me, though. I am a novice in this method. May 07 00:15:21 black_13: There is a lot of work that goes into compiling and cross-compiling. May 07 00:15:32 yes! May 07 00:15:35 it is not as easy as one, two, three. May 07 00:15:51 correct May 07 00:16:08 its better to download May 07 00:16:16 I used crosstools-ng for a while to set up an environment on my board. May 07 00:16:17 Yep. May 07 00:16:39 ... May 07 00:17:00 yeah you have to build the cross compiler then you have to build all your libs and then finally build your app May 07 00:17:10 that defines the march of time. May 07 00:17:38 Ah! May 07 00:17:44 Steps! May 07 00:18:17 Do you have this book, "Mastering Embedded Linux Programming?" May 07 00:19:01 it uses crosstools-ng instead of linaro toolchain. May 07 00:19:11 ah May 07 00:19:23 i could buy right now May 07 00:19:48 That book, once I read it, seemed to be straight forward and I got pretty far before I started to turn in dismay. May 07 00:20:51 i have done with yocto May 07 00:20:55 I got to the sqLite section on page 36 before the commands started to piss me off. May 07 00:20:56 Oh? May 07 00:21:15 and built usable images May 07 00:21:27 But page 36 was just an example. I did not need it. May 07 00:21:43 ... May 07 00:21:54 I have some yocto books but they are all outdated now. May 07 00:22:04 I stop testing w/ them recently. May 07 00:22:47 ... May 07 00:23:15 i have the 2015 version of the book you mentioned May 07 00:23:43 The book I was describing was produced in Dec. 2015. May 07 00:24:00 Yea. That book is older but it is useful. May 07 00:24:08 i.e. for a basis. May 07 00:24:19 ok i have it May 07 00:24:22 Oh! May 07 00:24:23 i just checked May 07 00:24:24 Cool! May 07 00:25:03 Three years back is ancient w/ all the people are doing w/ their current configurations of ideas. May 07 00:25:13 <<<< cannot keep up May 07 00:28:30 yea May 07 00:28:36 black_13: If you get bored or hung up, let me know. May 07 00:28:45 I will review what I have learned in that book. May 07 00:28:46 no i am reading May 07 00:28:54 Okay. May 07 00:30:03 set_: so you have such and such image on the beaglebone you use libs already on the box May 07 00:34:22 Um, what part are you on? May 07 00:34:28 Page#? May 07 00:34:55 around 36 May 07 00:34:59 Okay. May 07 00:35:00 Hold on. May 07 00:35:17 11 May 07 00:35:30 page 11 May 07 00:35:37 and talking to a guy at the bar May 07 00:36:06 Oh. May 07 00:36:08 Okay. May 07 00:36:22 but i am reading May 07 00:36:43 but your compiler kernel headers are important components May 07 00:37:26 Okay...so you got to QEMU already. May 07 00:38:20 sudo tunctl -u $(whoami) -t tap0 <<<<< see this section! I could not get this to configure on my Ubuntu Desktop correctly. I proceeded anyway. May 07 00:39:51 tunctl is old news or something. I am just not sure. I kept researching the idea and came up empty. May 07 00:39:53 Hold. May 07 00:40:08 ok i am going for a bit have to take my laundry home May 07 00:41:25 Okay. May 07 00:41:26 Later. May 07 01:05:17 set_: sir May 07 01:10:34 Yeppers!@ May 07 01:11:10 brb May 07 01:12:03 but all parts need to match up. May 07 01:17:14 what parts? May 07 01:17:40 pieces parts parts are parts. May 07 01:18:13 the set of sets that are not contained in the set May 07 01:18:26 Okay. May 07 01:19:03 If you download tunctl from sourceforge, let me know how it works. If not, use the instructions. Is your main rig a Ubuntu/Debian machine? May 07 01:19:32 my machine right now is windows and will run a vm May 07 01:20:03 That might work but I doubt. It is easier w/ Ubuntu/Debian machines. Serious. May 07 01:20:24 i can reboot on to ubuntu May 07 01:20:30 brb May 07 01:20:34 Okay. May 07 01:20:49 before i go what is tuncl May 07 01:21:16 tunctl is cmd from a project on Linux. May 07 01:21:37 ok brb May 07 02:26:18 join **** ENDING LOGGING AT Mon May 07 03:00:00 2018
