Jun 06 04:20:39 <as_win> i want to boot my beagle bone black with mlo,nk.bin,eboot files. any one suggest me steps to boot through sd card
Jun 06 04:33:37 <as_win> any one suggest me pls
Jun 06 04:55:22 <digit220> I'm having issues getting my beagle to go online. ifconfig -a doesn't show an eth0, and in /etc/network/interfaces is configured right
Jun 06 10:50:35 <ninekumar> hi
Jun 06 10:53:26 <karki> hello ?
Jun 06 10:53:35 <karki> I guess
Jun 06 10:54:18 <woglinde> gm
Jun 06 10:58:25 <ninekumar> hi
Jun 06 10:58:30 <ninekumar> this is naveen
Jun 06 10:58:43 <ninekumar> i work on labview
Jun 06 10:59:04 <ninekumar> is there any possibility that beaglebone interfacing with labview??
Jun 06 11:02:11 <ninekumar> r u dere??
Jun 06 11:04:21 <woglinde> what are you doing with labview?
Jun 06 11:04:48 <ninekumar> projects
Jun 06 11:06:30 <woglinde> what projects?
Jun 06 11:06:46 <ninekumar> home automation
Jun 06 11:06:51 <woglinde> and how do you thing the projects can run on the bone?
Jun 06 11:07:04 <woglinde> think even
Jun 06 11:07:48 <ninekumar> i didnt get u??
Jun 06 11:08:55 <woglinde> from the wiki page abut labview
Jun 06 11:08:58 <woglinde> I found
Jun 06 11:09:00 <woglinde> Compiled executables produced by version 6.0 and later of the Application Builder are not truly standalone in that they also require that the LabVIEW run-time engine be installed on any target computer on which users run the application.[1] The use of standard controls requires a runtime library for any language and all major operating system suppliers supply the required libraries for common languages such as C. However, the runtime r
Jun 06 11:10:30 <ninekumar> I found that there is some thing like BOTSPEAK --
Jun 06 11:10:50 <ninekumar> with the help of botspeak, we can interface beaglebone to labview
Jun 06 11:10:59 <woglinde> so you should find out if there is a LabVIEW run-time engine for linux-armv7a
Jun 06 11:12:57 <ninekumar> LabVIEW run time engine is available for linux
Jun 06 11:13:51 <SiC> I don't think you're looking for a runtime engine, I guess you're looking to interface a beaglebone into labview?
Jun 06 11:14:15 <SiC> so a PC is the host, and the beaglebone effectively becomes an I/O interface
Jun 06 11:14:24 <woglinde> ninekumar that does not mean it runs on the beagle
Jun 06 11:14:51 <ninekumar> hmmm.. that also supports my present task
Jun 06 11:15:43 <ninekumar> could u tell me how to make that ??
Jun 06 11:15:52 <woglinde> lol
Jun 06 11:16:18 <ninekumar> y that laugh??
Jun 06 11:16:51 <woglinde> sorry you are first here asking about labview
Jun 06 11:17:01 <ninekumar> oh god
Jun 06 11:17:23 <ninekumar> just type bot speak in the search box
Jun 06 11:17:34 <ninekumar> u will get a link for that
Jun 06 11:17:46 <ninekumar> if u want u can open it and u can check it
Jun 06 11:18:09 <ninekumar> https://sites.google.com/site/botspeak/supported-pro/beaglebone
Jun 06 11:18:20 <ninekumar> please check the above link
Jun 06 11:19:44 <karki> ninekumar : I'm officially working on supporting the Botspeak on BBB
Jun 06 11:19:48 <heeen> do you have to pull PWR_BUT to GND or to 3.3v to work
Jun 06 11:20:02 <karki> it's a ongoing project
Jun 06 11:20:14 <ninekumar> fine
Jun 06 11:20:32 <ninekumar> may i know to how much extent it has been done??
Jun 06 11:20:40 <ninekumar> thanks karki for ur info
Jun 06 11:21:17 <karki> ninekumar : It'll still be a month before I get anything working. I'm still working on the drivers
Jun 06 11:21:34 <karki> within a month you should be able to write simple programs
Jun 06 11:21:37 <woglinde> ninekumar hehe you are lucky
Jun 06 11:21:46 <ninekumar> :)
Jun 06 11:22:23 <ninekumar> I have downloaded the data... Many of the VIs are available
Jun 06 11:22:33 <ninekumar> missing with sub vis
Jun 06 11:23:42 <karki> ninekumar : I don't know LabView, but I do know botspeak ;) Once I have the interpreter ready, you can help me with the LV parts
Jun 06 11:24:17 <heeen> pwr_but has to be pulled to GND and is normally at 5V, is this correct
Jun 06 11:25:21 <karki> ninekumar : where are you from?
Jun 06 11:25:32 <ninekumar> Yeah definetly. i wil do that.. Then how to contact u???
Jun 06 11:26:56 <ninekumar> Hyderabad, Andhra Pradesh, India
Jun 06 11:29:00 <karki> I'm from bangalore
Jun 06 11:29:33 <ninekumar> nice
Jun 06 11:30:13 <ninekumar> what exactly botspeak is?? Is this any haraware device or a software??
Jun 06 11:30:50 <karki> ninekumar : https://github.com/deepakkarki/pruspeak ; still very alpha. Once I get the driver ready by this week, building an interpreter will take a two more weeks
Jun 06 11:31:06 <karki> ninekumar : botspeak is an language
Jun 06 11:31:18 <ninekumar> ok
Jun 06 11:31:32 <karki> so you need an interpreter to execute the botspeak code
Jun 06 11:31:48 <karki> LabView -> Botspeak is what happens
Jun 06 11:31:56 <ninekumar> fine
Jun 06 11:31:58 <karki> and then the botspeak code is interpreted!
Jun 06 11:32:21 <ninekumar> now the labview will communicate with beaglebone with the help of botspeak
Jun 06 11:34:37 <karki> http://botspeak.org/ for botspeak stuff. www.deepakkarki.github.io I have explained my project there.
Jun 06 11:35:24 <ninekumar> i checked botspeak.org earlier
Jun 06 11:35:48 <ninekumar> the other is not geting opened
Jun 06 11:36:41 <karki> ninekumar : http://deepakkarki.github.io/
Jun 06 11:36:55 <ninekumar> its fine
Jun 06 11:40:10 <ninekumar> so r u the developer of botspeak??
Jun 06 11:40:35 <karki> nah, thats chris rodgers
Jun 06 11:40:44 <ninekumar> ok
Jun 06 11:40:52 <karki> head of tufts university

Jun 06 11:43:06 <ninekumar> we can be in touch
Jun 06 11:45:31 <ninekumar> there is lot of stuff of labview with beaglebone??
Jun 06 11:45:36 <ninekumar> who made it
Jun 06 11:50:08 <karki> oops
Jun 06 11:50:26 <ninekumar> wat happended??

Jun 06 11:51:00 <karki> mail me if you have queries
Jun 06 11:51:29 <ninekumar> karki -- there is lot of stuff of labview with beaglebone?? who made all that??
Jun 06 11:51:37 <karki> ninekumar @gmail.com ?
Jun 06 11:51:43 <ninekumar> s
Jun 06 11:51:46 <ninekumar> karki
Jun 06 11:51:47 <karki> lots of contributors
Jun 06 11:51:58 <ninekumar> fine...
Jun 06 11:52:20 <karki> ninekumar : which project are you referring to?
Jun 06 11:53:50 <ninekumar> karki -- there are lot of vis of labview. For many simpler tasks like digital I/O, ADC etc
Jun 06 11:57:12 <karki> ninekumar : links pls, I haven't followed labview much since last year
Jun 06 11:58:30 <ninekumar> karki -- https://sites.google.com/site/botspeak/downloads

Jun 06 13:17:17 <karki> ninekumar : not yet
Jun 06 19:23:19 <dogrocket> anyone worked with spi on the beagle?
Jun 06 19:23:56 <Abhishek1> dogrocket: how's your kernel build now?
Jun 06 19:24:11 <dogrocket> works fine thanks!
Jun 06 19:24:20 <dogrocket> thanks for all the help
Jun 06 19:24:42 <Abhishek1> good to know, have fun :)
Jun 06 19:25:22 <dogrocket> i was leary of putting rcnelsons kernel image on arch linux distro but once i figured out where to copy all the files, it booted up no problem
Jun 06 19:31:23 <dogrocket> i have a bad issue now though, im using these wifi audio chips cc85xx and the ccdebugger you use to program them died. no longer recognized on usb.  Its put serious damper on project.  I found out the chips can be programmed with an spi connection and i guess beagle can connect spi... but how to implement it is another thing.
Jun 06 19:32:26 <dogrocket> i hate to spend more money on another flasher/debugger.. :P
Jun 06 19:52:31 <Abhishek1> dogrocket: did you try bonescript?
Jun 06 19:55:46 <dogrocket> bonscript has spi framework?
Jun 06 20:00:56 <LHartmann> Hello there
Jun 06 20:01:06 <LHartmann> Anyone working with the PRU?
Jun 06 20:01:23 <Abhishek1> didn'r really check, but there's a shiftOut function in the latest bonescript
Jun 06 20:01:24 <Abhishek1> if you just need to write a few bytes, it might be enough
Jun 06 20:01:38 <LHartmann> NOpe.
Jun 06 20:01:46 <LHartmann> Realtime data acquisiton.
Jun 06 20:02:05 <LHartmann> Motor control and such applications.
Jun 06 20:02:12 <agmlego> LHartmann: That comment was directed at dogrocket
Jun 06 20:02:24 <dogrocket> Abhishek1, i notice in example configuration script its all in hex, does spi use hex for everything or you know?
Jun 06 20:02:51 <agmlego> dogrocket: SPI is bytes.
Jun 06 20:02:58 <LHartmann> Oh, yeah. now I see his message. :-)
Jun 06 20:03:07 <agmlego> Bytes are generally shown in code as hex for compactness.
Jun 06 20:04:07 <Abhishek1> LHartmann: I am currently working on a logic analyzer with the PRUs on the BBB as a Google Summer of Code Project.
Jun 06 20:04:41 <LHartmann> Are you able to receive EVTOUT0 properly?
Jun 06 20:05:05 <Abhishek1> you using libprussdrv?
Jun 06 20:05:12 <LHartmann> I can only receive it once per run.
Jun 06 20:05:24 <LHartmann> Was before.
Jun 06 20:05:34 <Abhishek1> now?
Jun 06 20:05:38 <LHartmann> Right now I am using direct register a access.
Jun 06 20:06:02 <Abhishek1> okay, so you developed something like libprussdrv, correct?
Jun 06 20:06:05 <LHartmann> Built a set of data structures and bitfields for the full PRU memory map.
Jun 06 20:06:11 <LHartmann> Yup.
Jun 06 20:06:38 <Abhishek1> hmm, what's the frequency of receiving interrupts/
Jun 06 20:06:41 <Abhishek1> *?
Jun 06 20:06:59 <LHartmann> Unsure.
Jun 06 20:07:06 <LHartmann> Right now it is just a loop.
Jun 06 20:07:38 <LHartmann> My pru code just writes 0s to the data memory, sending one event every 256 bytes.
Jun 06 20:07:44 <Abhishek1> okay, do you clear the interrupts correctly? It might be the case that the interrupt flag is not cleared
Jun 06 20:07:51 <Abhishek1> ah, that's way too fast
Jun 06 20:07:59 <LHartmann> This is exacly where I am in doubt..
Jun 06 20:08:40 <Abhishek1> so you using printf's in your test code and connecting via SSH?
Jun 06 20:08:52 <LHartmann> By checking the libprussdrv code I see it clears the interrupt flag by writing 1 to the correct bit in SECR1
Jun 06 20:09:14 <LHartmann> Yes, SSH and printfs.
Jun 06 20:09:31 <Abhishek1> Ah, that causes over a millisecond or more of overheah
Jun 06 20:09:35 <Abhishek1> *overhead
Jun 06 20:09:38 <LHartmann> I do the same, but once cleared the interrupt does not happen again.
Jun 06 20:09:47 <dogrocket> Abhishek1: ok, im getting better understanding i guess.. :/
Jun 06 20:09:55 <LHartmann> How fast is the pru clock?
Jun 06 20:09:58 <LHartmann> 200MHz?
Jun 06 20:10:02 <agmlego> Yes.
Jun 06 20:10:04 <Abhishek1> yup
Jun 06 20:10:42 <Abhishek1> For my application, I decided to implement a kernel driver for the logic analyzer code as userspace was unable to keep up with the flow
Jun 06 20:11:24 <LHartmann> The writing loop has 4 instructions: SUB, SBBO, ADD, QBNE.
Jun 06 20:11:50 <LHartmann> I do 256 loops for every event...
Jun 06 20:12:11 <LHartmann> Yeah...
Jun 06 20:12:20 <LHartmann> That is still about 200kHz...
Jun 06 20:12:50 <LHartmann> I would fill the whole memory before trying to clear the flag. :-)
Jun 06 20:12:55 <Abhishek1> expect latencies in kHz
Jun 06 20:13:07 <Abhishek1> I mean, milliseconds
Jun 06 20:13:13 <LHartmann> got it
Jun 06 20:13:30 <LHartmann> I'll try a longer delay.
Jun 06 20:13:36 <LHartmann> thanks
Jun 06 20:13:49 <Abhishek1> and maybe execute your stuff like test > out.txt && out.txt
Jun 06 20:13:58 <Abhishek1> *&& cat out.txt
Jun 06 20:14:21 <Abhishek1> to reduce the printf and SSH overheads from impacting interrupt latency
Jun 06 20:16:00 <Abhishek1> LHartmann: also do try ^
Jun 06 20:16:16 <LHartmann> Will do
Jun 06 20:18:40 <Abhishek1> I'm currently working on the remoteproc implementation for PRU interface (unfortunately there isn't quite material or userspace libraries for this one) but it will replace UIO in the future. I'm building the logic analyzer core into this driver.
Jun 06 20:20:22 <LHartmann> nice
Jun 06 20:20:43 <LHartmann> Have you made anything available yet?
Jun 06 20:21:05 <LHartmann> I'd love to read it. :-)
Jun 06 20:21:38 <Abhishek_> Kernel driver is WIP, for info on the project: http://elinux.org/BeagleBoard/GSoC/2014_Projects
Jun 06 20:26:08 <LHartmann> Thanks for the help.
Jun 06 20:26:25 <LHartmann> See you around.
Jun 06 20:26:42 <Abhishek1> sure
