May 27 16:11:06 <kiran4399> alexhiam: ping..
May 27 16:12:30 <kiran4399> alexhiam: do you have any suggestions on what all to change to change in the defconfig file for the blue.
May 27 16:32:55 <chanakya_vc> hey mdp,bradfa,Are you there?
May 27 16:33:26 <chanakya_vc> hey foreverska !
May 27 16:33:39 <foreverska> hey chanakya_vc
May 27 16:34:03 <chanakya_vc> foreverska,  Just got over with my exams: )
May 27 16:34:15 <foreverska> Nice, how do you think you did?
May 27 16:35:03 <chanakya_vc> foreverska, Well it was electrical machines,a very tough subject.It went well though not in 90's range :(
May 27 16:35:51 <foreverska> One B shouldn't sink you.
May 27 16:36:33 <chanakya_vc> I need marks.Well it would be a A- if  I get in the 80's,
May 27 16:36:37 <chanakya_vc> foreverska, 6
May 27 16:36:43 <chanakya_vc> *^
May 27 16:37:30 <foreverska> Mmm yea I forget you're running for grad school.  Well here's hoping.
May 27 16:37:31 <chanakya_vc> Anyway,I am glad it's over.Finally can concentrate on GSOC
May 27 16:39:35 <chanakya_vc> foreverska, Yes I do.Although marks are not going to be the selling point of my application.Grad schools surely look at other stuff.
May 27 16:40:57 <foreverska> I'd have to assume so.
May 27 16:41:17 <chanakya_vc> foreverska, Marks are a necessity for my third year intern next year.A lot of companies prefer candidates with high marks(Samsung,Qualcomm,NXP,TI)
May 27 16:41:49 <chanakya_vc> So that's another headache
May 27 16:42:49 <chanakya_vc> Even Microsoft and Goldman Sachs
May 27 16:43:51 <foreverska> Well any of those will be great resume building.  I don't personally trust ex-MS employees but some people may.  lol
May 27 16:44:56 <chanakya_vc> foreverska, Why?Don't like Windows that much :P ?
May 27 16:45:21 <chanakya_vc> *Hate Windows that much :P
May 27 16:45:51 <foreverska> Yea... a Tandy I recently got with Windows 3.1 is the first time windows has been in my house in 3 or 4 years.
May 27 16:47:19 <chanakya_vc> foreverska, Haha. I started using Linux only about 6 months ago and I myself no longer use Windows anymore,except for when I have to play counter strike :P
May 27 16:48:14 <foreverska> CSS is on Linux.  Tends to run at a lower FPS but it's perfectly playable.
May 27 16:48:52 <chanakya_vc> foreverska, Anyway I am starting with the firmware part. Plan is to get a basic setup that is capable of bitbanging  up before wednesday.
May 27 16:49:31 <chanakya_vc> foreverska, Ohh I didn't know that. But many games like Age of Empires don't work.
May 27 16:50:41 <chanakya_vc> foreverska, Have you ever tried working with the AI behind AOE,it's super awesome piece of code! :D Although it allows the bot to cheat .
May 27 16:50:56 <foreverska> Very nice.
May 27 16:51:35 <foreverska> Never played AOE.  I did C&C as a teen and that was my only RTS.
May 27 16:54:55 <chanakya_vc> Ohh. You should try it once if you have the time! Even if you don't just see the AI part of it.Microsoft did a pretty excellent job with that.
May 27 16:55:02 <chanakya_vc> foreverska, ^^
May 27 16:55:55 <foreverska> Yea I've always heard it's a really good game but if it doesn't work on Linux I don't really have a way to play it.
May 27 16:55:58 <chanakya_vc> foreverska, Which linux do you use?Ubuntu?
May 27 16:56:57 <foreverska> Nah, debian.  I keep trying to use Suse for things but I have trouble getting it to fit the mold like I can Debian.
May 27 16:57:26 <chanakya_vc> foreverska, Ohh.I have my computer on dual boot so that I can play.Always good to have windows.Might need photoshop or  flash sometimes
May 27 16:58:16 <chanakya_vc> foreverska, Ohh! I have Ubuntu 14.04. I was thinking whether it be a good idea to upgrade to 16.04.
May 27 16:59:10 <foreverska> We've got flash via google-chrome.  You'll probably get MUCH better hardware support in 16.04.  I mean the kernel in 14.04 is still in the 3s.
May 27 17:01:33 <foreverska> Stable or LTS is basically just for older machines and/or office settings.
May 27 17:04:12 <foreverska> Debian Stable is unrunnable on my home machine short of major work because I have a 960 but Testing is perfectly fine.
May 27 17:09:08 <foreverska> You know what had an interesting AI that you might be interested in?  Creatures 3, released in 1999 and used NN for creature AI.  I vaugely remember a tool to manually edit the NN that ran the creatures.
May 27 17:13:01 <chanakya_vc> foreverska,  Ohh. I will check that out. I never played that game.Although I was three when it released so :P
May 27 17:13:26 <chanakya_vc> foreverska, I am stuck with Machine learning as of now. NN is distant dream as of now :P
May 27 18:04:13 <alexhiam> kiran4399: you've removed the MPU9150 iio driver?
May 27 18:05:08 <alexhiam> kiran4399: and why all the other changes?
May 27 18:06:39 <alexhiam> kiran4399: I'm looking at the bb_blue_api branch, is that right? try to keep the branches clean, i.e. one blue branch, then if you want to make a new branch for a particular thing give it a more specific name
May 27 18:07:55 <alexhiam> kiran4399: also, careful with your commit messages - the last one said you updated bb.org_defconfig but it was really bb_blue.org_defconfig
May 27 18:11:04 <alexhiam> jkridner: is there really nowhere to buy the robotics cape?
May 27 18:26:25 <chanakya_vc> Hey Wormo,alexhiam,are you there?Can you please help me with the Pru Software support package?
May 27 18:26:53 <chanakya_vc> mdp ^^
May 27 18:32:46 <alexhiam> chanakya_vc: I can try...
May 27 18:33:46 <chanakya_vc> alexhiam, I just have some fundamental doubts.I cloned the Pru sotware support from here:https://github.com/jadonk/pru-software-support-package
May 27 18:34:27 <chanakya_vc> alexhiam, Now essentially this contains the headers for writing code for PRU's right?
May 27 18:35:27 <chanakya_vc> So I would have to compile and link it using the PRU code generation tools right?Now what I understand is how do I give the path to the headers?
May 27 18:36:11 <chanakya_vc> alexhiam, Like when we install a new library for gcc,we have to give path for it.So that it is in the include folder.
May 27 18:36:32 <chanakya_vc> the header files
May 27 18:39:19 <alexhiam> well, yes, but that's 2 years old...
May 27 18:42:48 <chanakya_vc> alexhiam, I think it is the latest one.I don't think there has been upgradation to this.RPMsg hasn't changed
May 27 18:45:09 <alexhiam> chanakya_vc: yeah, that's using prussdrv, not remoteproc. Take a look at the beaglelogic and pruspeak code
May 27 18:45:13 <alexhiam> https://github.com/abhishek-kakkar/BeagleLogic/tree/master/beaglelogic-firmware
May 27 18:45:19 <alexhiam> https://github.com/deepakkarki/pruspeak/tree/master/src/pru-firmware
May 27 18:46:04 <chanakya_vc> alexhiam, Ohh so this is not using rproc.I will check out these links
May 27 18:46:09 <chanakya_vc> alexhiam, Thanks
May 27 18:48:53 <alexhiam> chanakya_vc: Abhishek will know more about it
May 27 18:58:55 <chanakya_vc> okay alexhiam I will try to catch him on the irc
May 27 19:34:52 <ZeekHuge> :(
May 27 19:34:59 <ZeekHuge> that is not working !
May 27 19:35:02 <ZeekHuge> Hey Wormo
May 27 19:35:06 <ZeekHuge> how are you ?
May 27 19:35:36 <ZeekHuge> the kernel we compiled using yakbuild, the modules produced by it arent loading.
May 27 19:35:54 <ZeekHuge> Exec fromat error.
May 27 19:35:58 <ZeekHuge> *format
May 27 19:42:58 <ZeekHuge>  make modules SUBDIRS=drivers/remoteproc ARCH=arm LOCALVERSION=-ti-r22 CROSS_COMPILE=/home/zeekhuge/Projects/OpenSource/toolchain/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
May 27 19:43:09 <ZeekHuge> command to build the omap_remoteproc module
May 27 20:21:39 <Wormo> ZeekHuge: 'Exec format error'? what does 'file' command have to say about it, is it even compiled for arm?
May 27 20:22:29 <ZeekHuge> omap_remoteproc.ko: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), BuildID[sha1]=a9d555b0b11d0665b2f803b6f2d9154c025ae374, not stripped
May 27 20:22:32 <ZeekHuge> Wormo: ^
May 27 20:22:57 <Wormo> does 'dmesg' have anything to say about it
May 27 20:23:12 <ZeekHuge>  make modules SUBDIRS=drivers/remoteproc ARCH=arm LOCALVERSION=-ti-r22 CROSS_COMPILE=/home/zeekhuge/Projects/OpenSource/toolchain/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
May 27 20:23:15 <ZeekHuge> command i used
May 27 20:24:11 <Wormo> looks ok, that's supposed to be the toolchain used, and the local version
May 27 20:24:17 <Wormo> so, dmesg?
May 27 20:24:36 <ZeekHuge> ahh   ....    omap_remoteproc: no symbol version for module_layout
May 27 20:24:56 <Wormo> kernel config is the wrong one somehow then
May 27 20:25:36 <Wormo> the prebuilt one has versioning on, as distro kernels do
May 27 20:26:43 <Wormo> what are you starting from for .cofig?
May 27 20:30:03 <chanakya_vc> Hey Zeekhuge!
May 27 20:31:02 <chanakya_vc> You had showed me the makefile for compiling the code for PRU.Could you point to that link once again?I can't seem to find on your git account.
May 27 20:31:48 <ZeekHuge> Wormo: Its working !
May 27 20:31:54 <ZeekHuge> the module got loaded !
May 27 20:32:12 <ZeekHuge> finally ! we have found the source kernel
May 27 20:32:18 <ZeekHuge> pheww ..
May 27 20:32:22 <ZeekHuge> hey chanakya_vc !
May 27 20:33:35 <ZeekHuge> chanakya_vc: https://github.com/ZeekHuge/PRU-framework/blob/master/firmware/src/Makefile
May 27 20:34:47 <chanakya_vc> Thanks ZeekHuge !
May 27 20:36:19 <ZeekHuge> :)
May 27 20:39:48 <chanakya_vc> ZeekHuge, In the line no 47,pru_vring.obj is the obj of the PRU code that we are trying to compile right?
May 27 20:45:35 <chanakya_vc> Or is it the file of the vring data structure?
May 27 20:55:26 <ZeekHuge> chanakya_vc: it is a requirement, that should already exist there before executing the command in that target . if there is a target that builds any of the prerequisites, it will be executed.
May 27 20:55:49 <ZeekHuge> the pru_vring is the file there in the firmware/src folder
May 27 20:58:54 <chanakya_vc> ZeekHuge, So rproc-pru1-fw.obj is the file we are trying to build right?
May 27 20:59:39 <ZeekHuge> chanakya_vc: http://www.gnu.org/software/make/manual/make.html#Rule-Syntax
May 27 20:59:42 <ZeekHuge> see this ?
May 27 20:59:54 <ZeekHuge> that is targets: prerequisites.
May 27 21:01:00 <chanakya_vc> ZeekHuge, Okay got that.
May 27 21:02:10 <chanakya_vc> ZeekHuge, Next I want to ask is the install-tobb part.Now what I understand out of this that you are basically sending the binary file to the bbb right?
May 27 21:03:26 <ZeekHuge> that is not written by me, its from the PRU-project, only some corrections that i made.
May 27 21:03:37 <ZeekHuge> i never tested that part
May 27 21:05:03 <ZeekHuge> what you need to do to test that is, just type in "make install-tobb" that should work provided you are connected to bbb through usb at 192.168.7.2
May 27 21:06:30 <chanakya_vc> ZeekHuge, Okay,so what I understand is that pru_vring file should be on the host computer for that right?
May 27 21:07:00 <chanakya_vc> Because it is a prerequiste for target that is prerequisite for install to bb
May 27 21:07:40 <ZeekHuge> exactly. pru_vring = pru_vring.c
May 27 21:08:14 <chanakya_vc> ZeekHuge, I think I get that the hang of it.
May 27 21:08:55 <ZeekHuge> yes you are !
May 27 21:09:23 <ZeekHuge> but, we arent suppose to use this pru-framework project for the rproc purposes.
May 27 21:09:31 <chanakya_vc> So if i were to name my firmware file as spi_bitbang, the name of the targets at line 47 and line 43 would change right?
May 27 21:09:32 <ZeekHuge> its old now
May 27 21:10:08 <chanakya_vc> ZeekHuge, ^^
May 27 21:10:31 <chanakya_vc> No I am only looking at it to compile my custom pru firmware and send it to the BB.
May 27 21:13:13 <ZeekHuge> what you need to do is, just replace all rproc-pru0-fw* with the firmware you want to load into pru0 and replace all rproc-pru1-fw* with the firmware you want to load into pru1.
May 27 21:13:26 <ZeekHuge> provided you will be using C.
May 27 21:14:21 <chanakya_vc> Yes I will be.I think I got the jist of the entire makefile.Although will take some time to get used to the syntax.
May 27 21:14:30 <chanakya_vc> ZeekHuge, ^^
May 27 21:22:25 <ZeekHuge> yes. Try it and let me know if that works. produces some error.
May 27 21:22:32 <ZeekHuge> chanakya_vc: ^
May 27 21:37:09 <Wormo> ZeekHuge: you should post what you learned about building modules for the selected baseline at the mailing list :)
May 27 21:38:56 <Wormo> clearly it was not previously well documented, with most people rolling their own BBB images or just using the prebuilt ones... not extending a prebuilt one with new modules
May 27 22:09:31 <ZeekHuge> okay Wormo
May 27 22:09:57 <ZeekHuge> and now, how should i go on with remoteproc  ?
May 27 22:14:24 <ZeekHuge> okay so 4.4 has pruss and pru_rproc https://github.com/beagleboard/linux/tree/4.4/drivers/remoteproc
May 27 22:14:37 <ZeekHuge> my source does not have it.
May 27 22:19:25 <ZeekHuge> okay so 4.4.11-ti-r28 has pruss remoteproc http://rcn-ee.net/deb/jessie-armhf/v4.4.11-ti-r28/defconfig
May 27 22:47:40 <zeekhuge_> Wormo: can there be something to commit out of this ?
May 27 22:48:15 <zeekhuge_> as there need to be 4-5 commits and i dont know what to commit
May 27 22:48:47 <zeekhuge_> also, where should i post it, beagleboard-gsoc, beagleboard or my blog ?
May 27 22:48:49 <amragaey> hi jkridner
May 27 22:50:02 <zeekhuge_> please do ans. I will see the logs. need to sleep now
May 27 22:51:55 <Wormo> ok zeekhuge_ I will catch up & reply
May 27 22:52:13 <Wormo> (still at work atm)
May 27 22:52:23 <amragaey> this link http://jadonk.github.io/bone101/Support/ isn't existing and cause error in htmlproofer, should I ignore it from breadcrumb, or make redirection to bone101 ? jkridner
May 27 23:06:48 <amragaey> jkridner, I added an empty index.html so Support can be found for now
May 27 23:25:37 <m_w> pmezydlo: You there?
May 27 23:25:47 <m_w> this may be faster than email
May 27 23:27:24 <pmezydlo> yes i am
May 27 23:28:30 <pmezydlo> m_w: ^^
May 27 23:28:44 <m_w> hey
May 27 23:29:08 <pmezydlo> m_w:hi now I try again
May 27 23:31:04 <pmezydlo> m_w:Unfortunately, after the installation dts connection bbb breaks off
May 27 23:31:21 <m_w> any output?
May 27 23:31:49 <m_w> I am going to load my BBB with a new image
May 27 23:31:59 <m_w> which image are you running?

May 27 23:32:59 <pmezydlo> http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot_lxqt
May 27 23:33:33 <m_w> okay the NULL pointer deference is it followed by a stack trace?
May 27 23:37:10 <pmezydlo> I'm not sure if it is what you are talking about:

May 27 23:38:07 <pmezydlo> ok

May 27 23:40:23 <m_w> hmmmmm
May 27 23:41:47 <pmezydlo> I will try on the old image
May 27 23:42:02 <m_w> try unloading spi_omap2_mcspi before loading the overlay
May 27 23:46:00 <pmezydlo> ok it works, I really didn't think about it
May 27 23:46:32 <m_w> okay
May 27 23:46:38 <m_w> here is something to think about
May 27 23:46:55 <m_w> what happens when you want to run and host and slave at the same time?
May 27 23:47:39 <pmezydlo> I do not know but I think it will be a problem
May 27 23:47:50 <m_w> are you sure?
May 27 23:47:53 <pmezydlo> I have to check it out
May 27 23:48:16 <m_w> you are using the same compatible string for both drivers
May 27 23:48:47 <m_w> so if both drivers are loaded they will both be probed
May 27 23:49:02 <m_w> for each SPI interface
May 27 23:50:42 <m_w> so you need to do something to disguish a slave registration from a host registration
May 27 23:53:27 <pmezydlo> thanks, tomorrow I will check it and write email to you. It's 2 am in poland.
May 27 23:54:01 <m_w> okay
May 27 23:54:52 <pmezydlo> bye
