<suma>

can anyone please help with the upgrade firmware procedure?

[00:16]

<suma>

open.neurostechnology.com <-- looks like it is very old and nothing related to the actual product

[01:01]

suma:

[01:02]

thats correct

[01:02]

best thing to do is update off usb disk (if on a middle-new(ish) firmware)

[01:02]

or, if that doesn't detect, use the emergency instructions (part 3 on that page)

[03:16]

<suma>

hi

[03:16]

<suma>

anybody help me in getting the firmware file

[03:16]

<suma>

r3.upk

[03:16]

<suma>

i have downloaded 6 times now and i could not get the md5 correct as mentioned in the website

[03:19]

<suma>

this is the MD5 i get 51625841590BD30360F7B117E653A8D4

[03:19]

<suma>

am i wrong

[03:19]

<suma>

97d78f2bea10ae062c082cb9503c1b52 this is mentioned in the website

[03:42]

sorry

[03:42]

i don;t know

[03:42]

try a different firmware?

[03:42]

<suma>

i uploaded that firmware, the same worked

[03:42]

<suma>

i took risk there

[03:42]

<suma>

but not every developer

[03:43]

<suma>

open.neurostechnology.com

[03:43]

<suma>

you tried the checksum on this webpage ?

[03:44]

<suma>

daurnimator: Looks like it is official and not properly maintained

[03:45]

<suma>

daurnimator: may i know the username and password to telnet into the device please ?

[03:46]

root

[03:46]

nothing

[03:49]

<suma>

daurnimator: where you get such information, i did not get in the wiki

[03:49]

i don't know

[03:49]

i've just been here for a while

[03:58]

<suma>

i c

[03:58]

<suma>

before i seen lot of applications

[03:58]

<suma>

when i upgrade there is zero applications, how can i bring them up ?

[04:01]

uh

[04:01]

you did?

[04:01]

<suma>

i did upgrade

[04:02]

<suma>

i told you before

[04:02]

i know

[04:02]

but, i've never seen any aps

[04:02]

<suma>

i did see lot of applications before

[04:03]

<suma>

Video Recorder, Music Player, etc.,

[04:05]

so u mean osdmain is not running?

[04:05]

<suma>

batmark: i dunno what is mean by osdmain ? !

[04:05]

blank screen on the tv

[04:05]

<suma>

I have four menu options

[04:06]

<suma>

Browse, Settings, Record and Other Programs

[04:06]

they probably just changed the ui a bit

[04:06]

just browse to what u want to play/watch and play it

[04:07]

<suma>

does it has smb client, becoz, i shared my files from the network and i could not access it

[04:08]

it should have smbclient but dont think they have done the gui for it yet

[04:08]

you can mount stuff through telnet

[04:08]

<suma>

batmark, shall i mount through the telnet and access through the browse menu ?

[04:09]

yeah thats the idea

[04:09]

<suma>

thanks

[04:09]

just make a directory in /mnt/OSD/tmpfs and mount it to there then u should be able to see it in the browse menu

[04:10]

* batmark waves good-bye

[04:10]

cyas all

[04:10]

<suma>

batmark: I can make the system to browse through the available smb server in the network right ?

[04:11]

it *should* work....... hopefully

[04:12]

<suma>

thanks

ha!

daurnimator: shame it doenst say nething bout neuros

[05:24]

i know

[05:24]

:s

[05:24]

<suma>

batmark: i'm still trying to configure samba client for the neuros !

[05:25]

suma: what problems are you having?

[05:25]

<suma>

mount -t cifs -o=ro //Csid4096383/TamilMovies /mnt/OSD/tmpfs

[05:25]

<suma>

mount: Mounting //Csid4096383/TamilMovies on /mnt/OSD/tmpfs failed: Invalid argument

[05:26]

<suma>

any suggestions ?

[05:26]

suma: try making a dir in /mnt/OSD/tmpfs and mounting there instead

[05:27]

<suma>

mount -t cifs -o=ro //192.168.0.10/TamilMovies /home/share/tmpfs

[05:27]

<suma>

this is perfectly working in my linux box

[05:28]

<suma>

but not in neuros

[05:28]

try "mount -t cifs -o=ro //Csid4096383/TamilMovies /mnt/OSD/tmpfs/TamilMovies"

[05:28]

<suma>

/mnt/OSD # mount -t cifs -o=ro //192.168.0.10/TamilMovies /home/share/tmpfs/TamilMovies

[05:28]

<suma>

mount: Mounting //192.168.0.10/TamilMovies on /home/share/tmpfs/TamilMovies failed: No such file or directory

[05:28]

<suma>

you want me to create directory ?

[05:28]

yeah

[05:29]

<suma>

i mean the TamilMovies one ! ?

[05:29]

yup

[05:29]

<suma>

mount: Mounting //192.168.0.10/TamilMovies on /mnt/OSD/tmpfs/TamilMovies failed: Invalid argument

[05:30]

<suma>

mount -t cifs -o=ro //192.168.0.10/TamilMovies /mnt/OSD/tmpfs/TamilMovies

[05:30]

hmmmm not really sure

[05:31]

try smbclient -L //192.168.1.10

[05:31]

<suma>

that works fine

[05:31]

<suma>

i get the list of directories shared

[05:31]

hmmmm looks like mount is not liking the cifs option

[05:32]

<suma>

there is no smbfs

[05:33]

is there a mount.cifs binary?

[05:34]

<suma>

yes

[05:34]

<suma>

there is one /sbin/mount.cifs

[05:35]

what about a smbmount?

[05:35]

<suma>

mount.cifs //192.168.0.10/TamilMovies tmpfs

[05:35]

<suma>

Password:

[05:35]

<suma>

could not update mount table

[05:36]

what about mounting to tmpfs/TamilMovies?

[05:37]

<suma>

mount.cifs worked

[05:37]

sweet u might what to put a bug in bugzilla and how you solved it

[05:38]

<suma>

sure

[05:38]

<suma>

batmark: i dunno how to play

[05:38]

what do you mean? browse to the file and then press play on the remote

[05:39]

<suma>

in the browse, i have only two

[05:39]

<suma>

network and usbdisk

[05:39]

<suma>

i don't know how to browse the local file system

[05:40]

hmmmm they might have changed the location again

[05:40]

what is the structure of /mnt?

[05:41]

<suma>

OSD tmpfs

[05:41]

the filebrowser lists IN OSD? - no?

[05:41]

whats in tmpfs?

[05:42]

ls -l /mnt/OSD

[05:42]

daurnimator: i cant remember it think they changed it

[05:42]

<suma>

ls -l /mnt/OSD

[05:42]

<suma>

[05:43]

maybe

[05:47]

<suma>

that worked

[05:47]

<suma>

batmark: thanks

[05:48]

is it browsing properly

[05:48]

suma: anyt time

[05:48]

<suma>

yes and i can also play movies

[05:48]

nice

[05:48]

<suma>

anytime, you want me to reboot and see it again ?

[05:49]

its fine

[05:51]

<suma>

Hi Batmark, how can i setup the toolchain for developing applications with neuros ?

[05:51]

just a sec and ill find you the wiki page for you

[05:52]

<suma>

batmark: is this the one ? wiki.neurostechnology.com

[05:52]

wiki.neurostechnology.com

[05:52]

just follow that and you shuld be fine

[05:56]

so, suma: you aren't returning it ;)

[05:57]

<suma>

daurnimator: looks like i can play with, actually I'm a Video IP Phone Developer and want to develop the phone for it

[05:57]

<suma>

also want to compile asterisk to work with it

[05:57]

hmm

[05:57]

how do you intend to plug in a mic

[05:59]

<suma>

audio input is there right ?

[05:59]

<suma>

it may need amplification, but that is not the real target here

[06:00]

<suma>

getting the rest to work with it

[06:00]

<suma>

we can certainly use USB to work with it

[06:01]

<suma>

with asterisk, i can use an IP Phone to get work with it

[06:01]

<suma>

IP Phone cost $20 each

[06:05]

suma: have you seen this open.neurostechnology.com look at number 5

ouch!

and i bet thats not all

[07:01]

batmark: do you know if anyone is working on a pkg manager?

[09:23]

<suma>

anybody here to help me in installing the toolchain

[09:28]

i can try .. because ive been going through now

[09:32]

<suma>

ymo000: thanks

[09:33]

<suma>

the way i have worked until now, is we used to set the compiler for the target

[09:33]

<suma>

and compiler any required library using the cross compiler toolchain

[09:33]

<suma>

and take the resulting binary and run in the target platform

[09:33]

<suma>

Looks like, i need to do something different here, can you help me please ?

[09:34]

<suma>

*compile

[09:34]

whats failing ?

[09:34]

<suma>

I dunno how to install the toolchain for the OSD ?

[09:35]

<batmark> wiki.neurostechnology.com

[09:35]

did you follow that ?

[09:35]

<suma>

yes i did and bit confused regarding the wiki

[09:36]

whats confusing ?

[09:36]

<suma>

svn co --ignore-externals svn.neurostechnology.com

[09:36]

<suma>

i did this

[09:36]

so ..

[09:36]

<suma>

i want to go with svn rather than tar.gz file, easy to manage in the future with svn update

[09:36]

<suma>

i have not got the tool chains

[09:37]

yes .. but what the problem ???

[09:37]

did you get an error on the svn co ? and what error ?

[09:37]

<suma>

ymo000: checkout few files

[09:38]

your not stating what was the problem so far

[09:38]

<suma>

after checkout what should i do !

[09:38]

ok .. then move on to the next step

[09:38]

its stated on the wiki

[09:39]

the procedure on the wiki take you from a to z in recompiling all the binaries of the OSD

[09:40]

did you get nfs and tftp going yet ?

[09:40]

<suma>

ymo000: i will go through again and try to grasp, sorry for that

[09:41]

ok

[09:41]

<suma>

i have enabled only the cifs, for sharing the windows shared folders

[09:41]

<suma>

i have not tried the nfs and tftp

[09:42]

ok ... i never tried samba

[09:42]

<suma>

nfs and tftp is for loading files to the OSD ?

[09:42]

i am having problems getting nfs to work right now :( i passed the tftp part

[09:43]

any expert on nfs around ?

[09:43]

<suma>

why nfs and tftp to build the binaries ?

[09:48]

suma, so that the OSD can boot (tftp) and load files via nfs

[09:48]

<suma>

you can also use samba too right ?

[09:48]

<suma>

i had set that one easily

[09:49]

not sure .. technically yes .. but not sure if its enabled. for the boot part i think its not there

[09:49]

<suma>

in my OSD it is working fine and i can play movies

[09:50]

<suma>

oh

[09:50]

<suma>

you want at the boot

[09:50]

suma, yes .. but for booting via smb i think you need uboot to support it

[09:50]

<suma>

yes

[09:51]

its not mentioned in the guide so it just did not cross my mind even :)

[09:52]

<suma>

i c

[09:52]

<suma>

you are writing some application for OSD ?

[09:54]

so far its called hello world !

[09:54]

<suma>

:)

[09:54]

how is the replay of files on the OSD ?

[09:54]

<suma>

replay ?

[09:55]

<suma>

you mean repeating the same song or movie ?

[09:55]

i went straight into development ... i never tried the functionality like playing movies

[09:55]

<suma>

oh i

[09:55]

<suma>

oh i c

[09:55]

<suma>

it can play audio and some of the videos nicely

[09:56]

what sort of videos codecs so far ?

[09:56]

<suma>

i played just avi files, in that it did not played few

[09:57]

<suma>

i have not fully analysed all the codecs

[09:58]

<suma>

I'm expertised in voip and video phones at the signalling level, not in the codec level

[09:59]

ah .. i saw you mentioned asterisk .. i come from a voip/telephony background as well

[10:00]

<suma>

that is very cool

[10:00]

suma, you want to run asterisk on the OSD ?

[10:00]

<suma>

that will be ideal i guessed

[10:00]

that piece of code is amonolith

[10:00]

<suma>

did not get you !

[10:01]

its a big piece of code

[10:01]

<suma>

yes, i'm aware of asterisk internals

[10:01]

<suma>

we can always through away unwanted ones first

[10:01]

did you try openser yet ?

[10:02]

<suma>

yes, used openser, exosip, ortp and developing phones with the same

[10:02]

the problem is that there is lot of it !

[10:02]

<suma>

asterisk is ideal one that can go along with OSD

[10:02]

why ?

[10:02]

<suma>

which can provide IVR, interfacing phones etc.,

[10:03]

<suma>

IAX needs zero configuration with respect to firewalls, etc

[10:03]

oh .. the ivr

[10:03]

<suma>

SIP is a big headache when traversing firewalls and negotiating with the remote endpoints etc.,

[10:03]

<suma>

yes, ivr, codec translation, etc.,

[10:03]

i never tried exosip, or ortp

[10:04]

<suma>

they are libraries

[10:04]

ah!

[10:04]

<suma>

ortp if for handling rtp

[10:04]

<suma>

you need to write code to develop ip phones

[10:04]

<suma>

they take care of the signalling part of SIP

[10:04]

have you done client sip code ?

[10:04]

<suma>

yes

[10:05]

so for a client sip lib which one you would go with ?

[10:05]

<suma>

working on that for 4 years

[10:05]

ah ! proprietery i guess ?

[10:05]

<suma>

we use osip and ortp

[10:05]

<suma>

yes proprietery

[10:05]

<suma>

not for me, but for my company

[10:05]

<suma>

i want to release GPL soon one

[10:06]

<suma>

asterisk compiles with ARM well, except it need to tidy up the unwanted code

[10:06]

is the lib doen from scrtach by you ?

[10:06]

<suma>

nope

[10:06]

<suma>

we use osip for parsing

[10:06]

<suma>

rest is from our part

[10:06]

<suma>

ortp for handling the rtp

[10:07]

suma, so techinchanlly you could do ivr this way

[10:07]

<suma>

yes

[10:07]

<suma>

but it takes long time to come to asterisk level

[10:07]

i have to check out osip then

[10:07]

<suma>

you are also interested in developing ip phone ?

[10:07]

yup

[10:08]

<suma>

Your expertise in ?

[10:08]

this was my original intent

[10:08]

<suma>

what is your are of expertise?

[10:09]

i ve done openser/asterisk interfacing with a j2me phone. i did the client side j2me in java and system design with openser

[10:10]

<suma>

that is cool

[10:10]

<suma>

you have done any modules in openser ?

[10:10]

no .. just getting it to work was a headache

[10:11]

<suma>

oh ok

[10:11]

the guys have funny function calls design

[10:11]

<suma>

yep

[10:11]

but it did the job .. so i never tried to change the internals

[10:11]

<suma>

you are familier with the asterisk 1.4 architecture ?

[10:12]

the last one i worked with was 1.2 .. just coming out at that time

[10:12]

this is brand new 1.4 right ?

[10:13]

whats changed in 1.4 ?

[10:13]

<suma>

the architecture is different compared to previous one

[10:13]

<suma>

yep

[10:14]

<suma>

not stable like 1.2, but architecture wise it is well designed

[10:14]

<suma>

uses xml based configuration

[10:14]

what about the forks ?

[10:14]

ah !

[10:14]

<suma>

yes if you want to use forks, it does use it

[10:15]

<suma>

if some module got problem, just removes that one from the system and does not affect the rest of the modules in the system

[10:15]

there was openpbx .. i kind of did not like the digium attitude

[10:16]

<suma>

yep

[10:16]

<suma>

you can also clone any version of asterisk and release the code under GPL

[10:17]

have you tried * on arm yet ?

[10:17]

<suma>

yes

[10:18]

is it stable even ? i remember i had to use monit to restart evry now and then when it borks

[10:18]

<suma>

I tried on arm, sh4, freescale

[10:18]

<suma>

it works fine

[10:18]

but you tried 1.2 or 1.4 ?

[10:18]

<suma>

yes, i tried 1.2

[10:18]

<suma>

I also got the 1.4 worked on kurobox

[10:18]

<suma>

it is a powerpc

[10:18]

you happen to have links for * on arm ?

[10:19]

<suma>

everything is documented internally inside the office, not allowed to release here

[10:19]

<suma>

what problem you had in arm ?

[10:19]

i meant just web links

[10:20]

just for reference once i try to do that

[10:20]

one cool app i was thinking was the usb channel bank form one company .. i cant remember the name :(

[10:21]

<suma>

the docs are not publically available to send the link to you

[10:21]

<suma>

if you face any problems, i can help you out

[10:21]

its ok ...

[10:21]

<suma>

USB channel bank nice idea

[10:21]

thnaks .. i might hold you to it ;)

[10:22]

<suma>

Now a days market prefers to be out of PC, USB market slows down

[10:22]

for people with less cash i am sure you have a sell

[10:22]

<suma>

yep

[10:23]

<suma>

i have taken OSD with interest to develop some cool applications

[10:23]

<suma>

especially to watch remote cable TV

[10:24]

whats the target app of your company ? server side , client side , billing ?

[10:24]

<suma>

We develop Video IP Phones

[10:24]

ah .. the OSD will work nice !

[10:24]

<suma>

using h.264

[10:24]

<suma>

not sure whether osd has the power for h.264

[10:25]

<suma>

for encoding and decoding simultaneously

[10:25]

what kind of horsepower do you need ?

[10:25]

because there is this dsp standing there ...

[10:25]

<suma>

we use seperate processor for h.264

[10:26]

the OSD has a separate DSP btw

[10:26]

<suma>

not sure of the requirements, i will discuss on wednesday and will get if you need more info

[10:26]

<suma>

we need to work on the assembly level to get it more perfect

[10:26]

<suma>

before that the signalling should be ready for that ones, sip will do its best for signalling

[10:26]

whaats the dsp you use if i can ask ?

[10:27]

<suma>

we work with davinci, and BF561 (blackfin)

[10:27]

insnt that the same dsp as in the OSD ?

[10:27]

<suma>

not sure, need to dig inside it

[10:27]

davinci

[10:28]

<suma>

You have idea on the OSD hardware ?

[10:28]

<suma>

It is not just hardware alone is important, also the development environment too. We use sophisticated tools to develop the DSP

[10:28]

<suma>

so optimisation is much easier when we pay more

[10:29]

<suma>

if neuros supplies some library that will be much wonderful

[10:29]

<suma>

or even we can take the open source x264 codec also

[10:30]

which x264 codec are you refering to ?

[10:30]

one sec ... i brb

[10:31]

<suma>

ok

[10:46]

<suma>

ymo000: u there

[10:49]

suma, i had someone on the line

[10:49]

<suma>

sorry,

[10:49]

<suma>

take you time, once you are back, give a ping

[10:49]

ok

[11:01]

<suma>

ymo000: do i have to move the extract of the neuros.tar.bz2 to the OSD directory ?

[11:12]

suma, i normally do the opposite ... just move the files inside the svn co files inside the the extract of the neuros.tar.bz2

[11:13]

<suma>

yes that makes the job simpler

[11:13]

suma, at the end of the day you need all files in the same dir. i even just co inside the OSD dir

[11:14]

<suma>

yes

[11:14]

<suma>

which build system you use ?

[11:14]

<suma>

i'm using fc5

[11:14]

<suma>
