  • [02:02:48] <macneib> ds2: Apologies, I didn't word my question properly. I agree about the hardware. Though I'm searching for a more in depth look at the software changes that need to take place. This is where my knowledge and experience drops off a cliff. You wouldn't happen to know where I could look to find out more about how to configure the SW side?
  • [02:03:57] <macneib> Even though each each LCd has a different wireup there is at least some general commonality between the LCd panels.
  • [02:15:18] <ds2> macneib: I am at lost for why people are looking for that even more... there are tons of examples in the tree
  • [02:15:37] <ds2> off the top of my head, look at what is done for the SDP or EVM
  • [02:15:51] <ds2> the SDP has 2 variants... the 2430 and the 3430... the LCD setup is the same
  • [02:16:15] <ds2> the N800/770 are probally the only poor example as they wire in the LCD differently
  • [02:17:50] <ds2> a quick summary - for the checked in omapfb driver - update your board file to declare there is a LCD. Add timing info... an example file is drivers/video/omapfb/lcd_2430sdp.c; most of the lcd_* files are also candidates for examples

  • [02:51:11] <mcm> unfortunately it gives me and error "No device detected" right after a warning "Could not open '/dev/fb': No such file or directory"
  • [02:51:54] <mcm> is there an option to omapfb that i can set to point to /dev/fb0 or /dev/fb1 ?
  • [02:52:01] <mcm> or how can i fix this ?
  • [02:52:11] <ds2> try symlinking it
  • [02:52:20] <ds2> but I think there is an option, try 'X -help'
  • [02:52:51] <ds2> might be good to verify your fb is working...i.e check for a logo on boot
  • [02:53:46] <mcm> fb is actually working. i get the beagle logo on startup with Robert's debian kernel.

  • [08:24:52] <ds2> wonder what would they say if a forwarding service sends it to general delivery
  • [08:24:53] <ds2> ;)
  • [08:24:58] <geckosenator> I"m not sure if you can forward to general delivery though
  • [08:25:07] <geckosenator> well usps does the forwarding
  • [08:25:09] <ds2> private forwarding service, not USPS
  • [08:25:12] <geckosenator> you fill out the old and new
  • [08:25:21] <geckosenator> not sure it's allowed
  • [08:25:26] <geckosenator> I haven't heard of private forwarding
  • [08:25:28] <ds2> the RV folks use those forwarding services a lot
  • [08:25:35] <geckosenator> my digikey order is up to $580
  • [08:25:45] <geckosenator> you picked out some expensive 2.5v regulators
  • [08:25:47] <ds2> Mail Boxes Etc/UPS Store can do that
  • [08:25:50] <geckosenator> ok
  • [08:25:57] <ds2> uh... not really
  • [08:26:05] <geckosenator> $2.25 each
  • [08:26:08] <ds2> if I get cheaper LDOs, then I have to get expensive caps
  • [08:26:22] <geckosenator> and the inductor
  • [08:26:26] <geckosenator> has a minimum order of 10
  • [08:26:32] <geckosenator> so I have to get $3 worth
  • [08:26:48] <geckosenator> my room mate woke up
  • [08:26:50] <ds2> feel free to mod the board... the 2.5V is easy to hack up and put in a different part
  • [08:26:55] <geckosenator> we are supposed to save his stranded dog
  • [08:27:11] <geckosenator> which fell down a coolar and is on a ledge on top of james peak at 12,700 ft
  • [08:27:41] <ds2> the inductor situation really blows... the alternative is a even more expensive inductor
  • [08:27:46] <geckosenator> well
  • [08:27:52] <geckosenator> I just wish I didn't have to get 10 of them
  • [08:27:52] <ds2> how did the dog get up to 12Kft?
  • [08:28:01] <geckosenator> he goes skiing with the dog
  • [08:28:06] <geckosenator> the dog runs behind

  • [08:28:33] <geckosenator> well maybe I can find an alternate inductor which is the same size but I can get just 1
  • [08:28:38] <geckosenator> even if it's 80 cents
  • [08:28:46] <ds2> the inductor isn't that critical... I think the main thing is 1210 foot print and 47uH w/300mA Isat or better
  • [08:29:01] <geckosenator> I have plenty of inductors
  • [08:29:06] <ds2> *nod* i do enough protos, that I much rather have extra inductors around
  • [08:29:09] <geckosenator> but they are all 5-20 amp ones
  • [08:29:11] <geckosenator> and 4-5 uH
  • [08:29:19] <geckosenator> well more like 1-20uH
  • [08:29:24] <ds2> 5-20A? that can't be 1210 footprint
  • [08:29:33] <geckosenator> they aren't
  • [08:29:37] <geckosenator> that's the point
  • [08:29:46] <geckosenator> they aren't even surface mount
  • [08:29:51] <ds2> ah I see
  • [08:29:52] <geckosenator> toroidal thru hole
  • [08:30:04] <geckosenator> well I"m just going to submit the order
  • [08:30:10] <geckosenator> hope I can forward to general delivery
  • [08:30:23] <ds2> well... I think this board is cheaper still compared to my first one
  • [08:30:28] <geckosenator> worst case it will get sent back and refund
  • [08:30:33] <geckosenator> right
  • [08:30:42] <geckosenator> sales tax is like $40
  • [08:30:45] <geckosenator> that's kind of crappy
  • [08:31:02] <ds2> this backlight driver is cheaper enough to offset the inductor costs...first version has a cheaper inductor but more expensive chip ($4-$5)
  • [08:31:13] <geckosenator> yeah
  • [08:31:45] <geckosenator> well I have to go.. I wonder if the dog is still there or not...
  • [08:31:53] <ds2> if the inductor cost you $3 total, you would need to find one that is under $1.50 to come out ahead anyways
  • [08:32:03] <ds2> heh... poor frozen dog ;)

  • [17:32:33] <pro-rsoft> ds2, so I target an arch?
  • [17:32:37] <ds2> OE is a build system; Angstrom is a distro maintained by many volunteers, including Koen (correct me if I am wrong abut this)
  • [17:32:45] <Crofton|work> ds2, right :)
  • [17:32:47] <ds2> pro-rsoft: yes. you always target an arch.
  • [17:32:49] <pro-rsoft> ok
  • [17:32:54] <Crofton|work> Angstrom is built with OE :)
  • [17:32:55] <pro-rsoft> ds2, so my kernel would work with any distro
  • [17:33:04] <pro-rsoft> if I would build a kernel with OE.
  • [17:33:12] <pro-rsoft> or .. how does it work
  • [17:33:24] <AV500> pro-rsoft: the kernel you have on your BB does not seem to have the PM framework that the SGX driver expects
  • [17:33:26] <ds2> pro-rsoft: in theory unless the distro wants to use odd ball and unsupport (as far as proper kernel developers are concerned) features.
  • [17:33:38] <AV500> so it does not build. now you either change the kernel or the driver
  • [17:34:07] <pro-rsoft> AV500, ok. So, where can I get a kernel - by building it, or is there some quick way I can download it
  • [17:34:12] <ds2> SGX support is pretty straight forward. Grab stuff. Tell Kbuild where kernel is. build it. boot said kernel and load modules. Shove in libraries and go.
  • [17:34:36] <pro-rsoft> ds2, of course. But it failed on the "build it" step.
  • [17:34:39] <pro-rsoft> It didnt like my kernel headers.
  • [17:34:47] <ds2> then read the docs on Kbuild
  • [17:34:49] <pro-rsoft> or rather: wasnt compatible with my kernel version
  • [17:34:58] <pro-rsoft> the *source* isnt compatible with my kernel version.
  • [17:35:03] <ds2> you are not invoking kbuild with the right incantations
  • [17:35:12] <pro-rsoft> lol
  • [17:35:16] <ds2> somehow I doubt that...
  • [17:36:10] <pro-rsoft> ds2, for example, it included asm/semaphore.h instead of linux/semaphore.h (has been moved in a certain kernel ver)
  • [17:36:50] <pro-rsoft> ds2, I'm stuck here http://article.gmane.org/gmane.linux.ports.arm.omap/17405
  • [17:37:09] <pro-rsoft> (thats not me but I had the exact same things)
  • [17:37:22] <AV500> yes, but cnstr_id_vdd2 and RES_OPP_CO are under CONFIG_OMAP3_PM, so unless you have this, symlinkin will not help

  • [17:43:10] <ds2> S-Video out is nice but the Beagle and Leopard both can do that where as none of them can do S-Video in
  • [17:43:22] <khasim> I initially thought TV out is good, but then felt like it would be redundant with VGA out being available
  • [17:43:50] <ds2> VGA out is just a DAC on top of the HDMI stuff, right?
  • [17:44:09] <khasim> it is a different transceiver,

  • [17:47:00] <ds2> pro-rsoft: I donno where you are getting the stuff... but I compiled that thing about 3 weeks ago and it took all of 20minutes and that was on a slow machine
  • [17:47:25] <pro-rsoft> ds2, but you are running either an older kernel than .28 *or* are using OpenEmbedded right?
  • [17:47:45] <ds2> pro-rsoft: I am using my own .28 kernel
  • [17:47:54] <khasim> ds2: yeah, I thought so, but cost will go high. anyway the signals will be made available to add LCD, DVI or any other stuff
  • [17:48:02] <pro-rsoft> ds2, OE?
  • [17:48:04] <ds2> in fact I am several revs behind the Angstrom DSS patch
  • [17:48:11] <pro-rsoft> hmm
  • [17:48:19] <ds2> pro-rsoft: I have most of the OE patches but that's cuz I need those things
  • [17:48:30] <pro-rsoft> ds2, where can I get those OE patches
  • [17:48:47] <AV500> khasim: what can it do with video-in?
  • [17:48:51] <AV500> there an ISP or so?
  • [17:48:57] <khasim> AV500, ds2, Crofton|work,: I will go with Svideo In and remove S-video out by default and give it on expansion
  • [17:49:17] <khasim> there is only video port interface,
  • [17:49:19] <khasim> no ISP,
  • [17:49:24] <ds2> khasim: yes but VGA out is expensive (relatively) speaking
  • [17:49:29] <pro-rsoft> khasim, so what exactly is this? new beagle rev?
  • [17:49:32] <khasim> but DSP can be used to do some processing
  • [17:49:40] <Crofton|work> I mostly do not use monitors :)
  • [17:49:51] <Crofton|work> the dsp is interesting
  • [17:49:55] * PhastPhrog_ (n=chatzill@194.193.86.112) has joined #beagle
  • [17:50:04] <khasim> pro-rsoft: it is a low cost board using OMAP L 138 (ARM 9 + DSP floating point)
  • [17:50:10] <ds2> khasim: I can make demo projects for you for the S-Video in functionality if I can get a board
  • [17:50:10] <khasim> both running at 300Mhz
  • [17:50:17] <pro-rsoft> khasim, whats it called
  • [17:50:31] <khasim> pro-rsoft: no naming done yet,
  • [17:50:33] <pro-rsoft> ah, ok
  • [17:50:36] <ds2> khasim: know if the L138 board supports USB device (gadget) mode?
  • [17:50:47] <pro-rsoft> khasim, so, a sort of beagle thing but more powerful
  • [17:50:51] <khasim> currently I am looking at what is good for us, based on that I will figure out the cost factor
  • [17:50:59] <pro-rsoft> cool
  • [17:51:01] <khasim> less powerful I would say
  • [17:51:06] <pro-rsoft> ok
  • [17:51:14] <ds2> pro-soft: your local friendly OE repo of course.
  • [17:51:22] <pro-rsoft> which I dont have ;)
  • [17:51:24] <khasim> as ARM can run at 300 Mhz, DSP at 300Mhz, but lot of peripherals, like SATA, etc

  • [17:52:02] <khasim> :)
  • [17:52:14] <ds2> =)
  • [17:52:28] <khasim> can you guys give me a price for this ----
  • [17:52:32] <AV500> khasim: what does this VPIF do? just a 565 input?
  • [17:52:34] * jkridner|work1 (n=a0321898@nat/ti/x-1c615ecf5f277208) has joined #beagle
  • [17:52:50] <ds2> Same $150?
  • [17:53:00] <khasim> no not at all
  • [17:53:03] <ds2> is the L1 doable w/o blind vias?
  • [17:53:22] * john3909 (n=jsynesio@99-26-125-126.lightspeed.sndgca.sbcglobal.net) has joined #beagle
  • [17:53:24] <ds2> blind vias are a real cost issue
  • [17:53:34] <khasim> AV500: VPIF is same as in Davinci I think,
  • [17:55:22] <ds2> is it a microbga (0.4mm pitch) package?
  • [17:55:34] * jkridner|work (n=a0321898@nat/ti/x-a9e8ca741fa06360) Quit (Remote closed the connection)
  • [17:55:38] <khasim> I think it supports .65 and .8
  • [17:55:49] <ds2> hmm no datasheet
  • [17:55:53] <AV500> khasim: ok, so CCD/565 input
  • [17:56:10] <ds2> Oh nice.... 0.65 is doable w/o microbgas so the board and assembly could be cheap
  • [17:56:14] <khasim> AV500: here you go

  • [17:56:42] <khasim> koen: correct
  • [17:57:06] <khasim> koen: In India it is still popular as it is low cost
  • [17:57:11] <koen> khasim: I'd rather have DVI-D (or proper hdmi, but that's $$$ for licensing)
  • [17:57:11] <ds2> I suppose VGA can be used as a component interface
  • [17:57:33] <AV500> if it is the same as davinci it has 4 dacs
  • [17:57:38] <khasim> koen: I am pushing more for a UI board
  • [17:57:57] <AV500> which can generate comp/SVideo/component and VGA
  • [17:58:01] <khasim> LCD + Touchscreen
  • [17:58:15] <ds2> AV500: component and VGA can share
  • [17:58:22] <ds2> just as S-Video/composite can share
  • [17:58:44] <khasim> Base board has VGA and Composite In as default. Composite out, LCD signals on expansion slot
  • [17:58:49] <ds2> LCDs could make the board expensive
  • [17:59:14] * _gm_ (n=_gm_@190.173.100.86) has joined #beagle
  • [17:59:20] <AV500> ds2: yes of course

  • [17:59:28] * jso (n=user@151.159.91.148) has joined #beagle
  • [17:59:36] <khasim> only base board at a price + if you need UI it costs extra
  • [18:00:04] <ds2> khasim: I like that... third parties can produce alternative UI board for whatever people want
  • [18:00:30] <koen> khasim: I'd add dvi as default and have vga as extra
  • [18:01:20] * FuL|OUT is now known as fulgas
  • [18:01:27] <khasim> Please confirm the spec before I freeze : VGA out, Composite In, DDR 128, NAND 128, Ethernet, USB Host, USB OTG, UART, Audio out/in, SATA out, GPIO, PWM, MMC/SD slot,
  • [18:01:27] <ds2> I wonder how programmerable is the LCD control on that L138...
  • [18:01:39] * _Lucretia_ wonders if there is a touchscreen component for bb? i.e. one that isn't packaged in a housing
  • [18:01:42] <koen> khasim: vga is a waste of space and mnoney
  • [18:01:50] * eFfeM always liked marvell 88w8618; linux, wifi, usb otg, audio in/out; was aimed for voip phones, unfortunatley never got a source for boards (only got one sample). would love TI to beat that (price indication I got was < usd 30 for reasonable volume)
  • [18:02:13] <ds2> khasim: what about power? 5V?
  • [18:02:18] <koen> eFfeM: I haven't seen anything from ti with integrated wifi yet
  • [18:02:19] <ds2> and any RTC?
  • [18:02:30] <koen> battery backed rtc?
  • [18:02:36] <khasim> koen: I agree with you 100%, but the students community in India will have to pay additional 8000Rs to buy a DVID - it is bit costly.
  • [18:02:48] <khasim> yes USB and externally powered
  • [18:02:53] <eFfeM> koen actually marvell only integrated the mac, it required a separate phy
  • [18:02:58] <koen> khasim: students are poor by definition :)
  • [18:02:58] <AV500> khasim: if you have compIN, also add compOUT!
  • [18:03:04] <khasim> koen: yes Battery backed RTC at additional price :)
  • [18:03:11] <ds2> koen: if the LCDC on the l138 is flexible enough; the VGA can be a DDS output
  • [18:03:46] <koen> khasim: I don't have any vga cables any more :)
  • [18:03:51] <ds2> with 3 channels, it can do quadratures... add in a minicircuits mixer and you can turn it into a radio
  • [18:03:54] <khasim> koen: I put it otherway, students who really want to learn and contribute are poor .. I want to do some thing for them :)
  • [18:03:58] <koen> khasim: what about a dvi port with dvi-a and dvi-d?
  • [18:03:59] <AV500> khasim: if you want cheap then go comp in/out, there should be TVs in india, no?
  • [18:04:18] <koen> AV500: no tvs, only vga monitors :)
  • [18:04:31] <khasim> AV500: yes comp in/out tvs are available at low cost.
  • [18:04:33] <ds2> khasim: my only concern with VGA and DVI is heat... so I would strongly recommend having a disable for the transceivers on a GPIO
  • [18:04:33] <AV500> I bet you the ratio tv:vga is high
  • [18:04:38] <khasim> but cost is going high when I add both
  • [18:04:45] <ds2> (and power consumption)
  • [18:05:00] <AV500> so drop vga, what for. what kind of super fancy UI are you going to make on that 300mhz arm9?
  • [18:05:08] <khasim> ds2: not sure about power consumption, it should be similar to beagle
  • [18:05:24] <ds2> khasim: if I am not using the VGA, I would like a easy way of disabling the transceiver
  • [18:05:39] <khasim> ds2: ok
  • [18:05:41] <ds2> just like Gerald has the GPIO to disable the TFP xmitter on the beagle
  • [18:05:53] <AV500> khasim: to have a simple DSP demo, you just hook up a 10$ PAL cam and a 20$ PAL TV
  • [18:05:59] <khasim> AV500: I agree the LCD out is not so cool as OMAP3, but just to give a UI experience

  • [18:06:19] <ds2> it is easy to build a LCD interface ;)
  • [18:06:28] * ds2 ducks before all the rotten tomatos fly
  • [18:06:32] <AV500> my pick: base unit: comp in/out
  • [18:06:41] <AV500> +LCD/TS unit for "embedded" use
  • [18:06:44] <hrw> ds2: if you have beagleboard Cx you mean
  • [18:06:45] <hrw> ?
  • [18:06:47] <khasim> Yes, the LCD is much easier to develop, I would insist that, and allow disabling of VGA
  • [18:06:50] <AV500> +maybe VGA/DVI out
  • [18:07:28] <khasim> Apart from VGA / DVI any other concerns do you have with this spec?
  • [18:07:40] <ds2> hrw: yes... my point is if the signals are exposed it is trivial... for a RevB, it is trivial if you care apt at tacking on wires to a QFP (Geckosenator on here has done that)
  • [18:07:59] <AV500> khasim: fine with me
  • [18:08:31] <khasim> AV500: Comp in and VGA out... and LCD at low cost - how is this acceptable
  • [18:08:41] <ds2> khasim: an RTC would be nice given all the demand for it
  • [18:08:51] <koen> khasim: what about compat with e.g. leopardboard expansions?
  • [18:08:52] <AV500> khasim: if you have VGA out, it can also do COMP out, no? same DAC, no?
  • [18:08:54] <khasim> ds2: RTC by default?
  • [18:09:12] <AV500> RTC? what for, the thing has eth0
  • [18:09:22] <ds2> khasim: yes... unless the L138 also uses the TWL4030 (or equiv) with a built in RTC
  • [18:09:33] <AV500> it has all the NTP time it can get
  • [18:09:45] <khasim> AV500: I think yes, I will confirm
  • [18:09:49] <ds2> AV500: to do Comp out, you need 1 more chip
  • [18:10:01] <AV500> just use on of the VGA video amp
  • [18:10:11] <ds2> ewwwww NTP sucks if you are isolated or cannot afford power for eth.
  • [18:10:41] <ds2> AV500: no... you need to phase modulate it with the color burst + combine h/vsync
  • [18:10:41] * pH5 (n=ph5@e178193101.adsl.alicedsl.de) Quit ("bye")
  • [18:11:00] <ds2> sync combination can be done with passives but the phase modulation needs an active thing to generate the color burst
  • [18:11:00] <AV500> well, thats what the chip itself does, at least on the davinci
  • [18:11:06] <AV500> ds2: nope
  • [18:11:16] <AV500> all out of the DAC, just amplify
  • [18:11:24] <ds2> AV500: Hmmmm
  • [18:11:38] <AV500> IF this is like davinci, which I guess as they just reuse IP they have
  • [18:12:06] <AV500> DV has 4 dacd which can do composite/SV/VGA/component
  • [18:12:10] <AV500> dacs
  • [18:12:23] <ds2> 4 DACs?!
  • [18:12:32] <AV500> davinci, yes
  • [18:12:41] <ds2> you mean it can output 4 different things at once?
  • [18:12:55] <AV500> yes, R, G, B and BBC1
  • [18:13:03] <ds2> what's BBC1?
  • [18:13:26] <AV500> sorry, joking
  • [18:13:34] <ds2> Oh you are in the UK? ;)
  • [18:14:05] <ds2> 4 DACs almost seems to mean R/G/B for VGA and 1 other DAC+modulator for the composite/SV side
  • [18:14:19] <khasim> AV500: do you what transceiver we use on Davinci ?
  • [18:14:33] <khasim> I can check it out.... but not now :)
  • [18:14:57] <AV500> ds2: not in UK, I just picked a well know radio station
  • [18:16:12] <_Lucretia_> it's a tv station
  • [18:16:22] * dhairya (n=dhairya@116.72.175.194) has left #beagle
  • [18:16:26] <khasim> I will check on the Composite and VGA portion of spec. Will try for RTC

  • [18:16:40] <khasim> let me get back when the spec gets confirmed
  • [18:16:47] <khasim> thanks for all the inputs....
  • [18:17:42] <AV500> khasim: if this is like DV, then at least there could be a jumper that select RGB or comp on one of the DACs, problems solved
  • [18:17:57] <AV500> err, on one of the video amps
  • [18:18:19] <khasim> AV500: will give some thought about this.
  • [18:18:45] <khasim> thanks a lot
  • [18:19:11] <khasim> but then it has to be hooked onto VPIF or LCD controler ?
  • [18:19:28] <khasim> the VPIF support in kernel is very bad for now.
  • [18:19:35] <khasim> it is based on V4L,
  • [18:19:43] * lifeeth_ (n=praneeth@unaffiliated/lifeeth) has joined #beagle
  • [18:19:52] <khasim> so have to go with LCD controller and get FBDEV support for this
  • [18:20:35] * lifeeth (n=praneeth@unaffiliated/lifeeth) Quit (Remote closed the connection)
  • [18:21:22] <AV500> khasim: ??? what needs to be hooked?
  • [18:21:27] * lifeeth_ is now known as lifeeth
  • [18:21:31] * koen likes how khasim implies that v4l is bad :D
  • [18:22:22] <ds2> V4L is indeed bad.. at least do V4L2 ;)
  • [18:22:47] <AV500> ds2: I guess they all mean that :-)
  • [18:22:47] <khasim> AV500: I mean choosing the VPIF or LCD controller for VGA/composite out
  • [18:23:14] <ds2> AV500: uh... err...not necessarily
  • [18:23:18] <khasim> VPIF uses V4L2, LCD controller uses FBDEV
  • [18:23:36] <AV500> khasim: yes, but VGA would not be on LCD controller, no?
  • [18:23:51] <ds2> V4L2 output isn't that common (as far as apps)?
  • [18:24:07] <khasim> AV500: I was thinking so :)
  • [18:24:31] <khasim> I was thinking of interfacing VGA to LCD controller
  • [18:24:46] <AV500> I thought you want cheap?
  • [18:25:03] <khasim> so that we can use FBDEV for output
  • [18:25:26] <AV500> that is unrelated to the actual interface, no?
  • [18:25:40] <ds2> probally more people understand fbdev for output then v4l2 for output
  • [18:25:51] <AV500> khasim: how many DACs does the L138 have?
  • [18:26:01] <AV500> enough for VGA out or not?
  • [18:26:07] * koen wonders what the $*(@*$(@ is up with mythtv buffering
  • [18:26:12] <AV500> 1 or 4? or 0?
  • [18:26:19] <koen> live TV stutters every 3 seconds on the beagle
  • [18:26:53] <AV500> khasim: we do PAL/NTSC/component out via the 4 DACs of the davinci and it is FBDEV we are using!
  • [18:27:12] <ds2> koen: what tuner are you using?
  • [18:27:39] <koen> ds2: PVR150 in an x86 box streaming mpeg2 over the network
  • [18:28:17] <ds2> Oh BAH
  • [18:28:17] <koen> I could try dvb over usb, but I suspect that will suffer from the same buffering issue
  • [18:28:29] <AV500> khasim: unless I see a block diagramm, I can only speculate.
  • [18:28:30] <ds2> koen: I thought you had DVB over USB working :D
  • [18:28:44] <koen> ds2: no, I can't get tuning to work properly
  • [18:28:44] <ds2> koen: maybe the ethernet overUSB is choking?
  • [18:29:09] <koen> ds2: the ethernet seems to be fine
  • [18:29:30] <ds2> koen: at the speeds you need it for live TV?
  • [18:29:38] <khasim> AV500: I will work on this and make sure we use FBDEV and hit low cost ..
  • [18:29:45] <koen> ds2: 6Mbit mpeg2
  • [18:29:48] <ds2> koen: any errors showing up on ifconfig?
  • [18:30:00] <ds2> 10baseT or 100baseT or GigE?
  • [18:30:17] <ds2> 6M could be pushing it for 10
  • [18:30:17] <koen> RX packets:135089 errors:0 dropped:0 overruns:0 frame:0
  • [18:30:17] <koen> TX packets:82550 errors:0 dropped:0 overruns:0 carrier:0
  • [18:30:23] <AV500> khasim: looking at the L137, I see nothing like DV osd controller, so LCD out might be the only thing
  • [18:30:23] <koen> 100Mbit/s
  • [18:30:38] <AV500> so probably 0 dacs :-(
  • [18:30:41] <khasim> AV500: L137 is not having VPIF
  • [18:30:48] <khasim> L138 has VPIF
  • [18:30:49] <ds2> koen: neon or dsp?
  • [18:31:00] <ds2> also which USB, EHCI or MUSB?
  • [18:31:08] <koen> ds2: I patched mythtv's copy of ffmpeg with mrus magic
  • [18:31:12] <AV500> so VPIF is IN and OUT?
  • [18:31:38] <khasim> AV500: so use LCD out signals, put a transceiver on board and give it on VGA out just like we do on beagle for DVID
  • [18:31:46] <koen> ds2: the next mythtv release should have neon by default :)
  • [18:31:55] <AV500> yes, but xpensive
  • [18:32:04] <ds2> koen: doesn't neon decoding peg the peg? prehaps it is cpu competitionwith UI and USB?
  • [18:32:18] <khasim> AV500: Use the VPIF input put a transceiver and get the composite in
  • [18:32:29] <koen> ds2: mplayer can play the same stream fine
  • [18:32:31] <AV500> but, this LCD controller, can it show video? is there an OSD with mutlitple planes? or is it like DVHD that can only show video in/out
  • [18:32:40] <koen> ds2: I suspect sucky buffer management
  • [18:32:43] <ds2> koen: mplayer's UI is cruder
  • [18:33:07] <khasim> AV500: there is no multi-plane, just one plane
  • [18:33:24] <AV500> so you cannot mix OSD and video
  • [18:34:05] <ds2> hmmmm seems like there is just 1 thing missing from each of the 3 boards
  • [18:34:09] * AK6L (n=xunil@nowai.yar.ly) has left #beagle
  • [18:34:21] <ds2> proposed L138 - no hardware video compressor/accelerator
  • [18:34:39] <ds2> Leopard - no S-Video in, but accelerated
  • [18:34:45] <AV500> ds2: yes, I expected that
  • [18:34:46] <koen> ds2: iirc l137 is targeted at audio

  • [18:36:19] <AV500> ds2: yes you did
  • [18:36:37] <ds2> like the econ folks say... economic is because you can't get everything you want :D
  • [18:37:05] <koen> a davinci type chip with a cortex and sgx would be neat
  • [18:37:29] <AV500> to have 3d and HD on crappy analog TVs? what for :-)
  • [18:37:58] <khasim> ok, no mixing possible
  • [18:37:58] <ds2> koen: In theory, the DSP should be able to do it all
  • [18:38:10] <ds2> AV500: 3D on TV isn't that bad
  • [18:38:14] <khasim> do you think composite in will still make sense
  • [18:38:31] <AV500> khasim: what would you use the DSP for?

  • [18:38:42] <ds2> khasim: it would be a very simple way of providing video input
  • [18:38:59] <ds2> USB cameras have software issues; raw CMOS sensors are expensive in small quantities
  • [18:39:18] <koen> ds2: compat with leopardboard sensors would be neat
  • [18:39:25] <ds2> plus SVideo in lets you interface with other legacy stuff
  • [18:39:30] <koen> since you can get those relatively cheap
  • [18:39:31] <khasim> At present as ds2 said it was targetted for audio apps,
  • [18:39:33] <AV500> I you have comp in you can do things like face recognition etc on the DSP
  • [18:39:44] <ds2> koen: would be but I wish the leopard had S-Video in
  • [18:39:48] <AV500> then the L137 is enough, no?
  • [18:39:55] <khasim> koen: DM355 has ISP,

  • [18:40:48] <ds2> [L138] -USB- [Beagle|Leopard]
  • [18:40:55] <ds2> it'd be a remote sensor thing
  • [18:41:06] <khasim> ds2: ok
  • [18:41:20] <koen> khasim: no, the leopard board have exchangable sensors, would be nice to use those sensors on l13xc
  • [18:41:23] <AV500> khasim: if the emphasis is not on video processing and no way to mix with OSD, then drop video in
  • [18:41:36] <khasim> AV500: 137 should be good, but 138 gives VPIF, SATA,
  • [18:41:36] <koen> ds2: wasn't there an svideo in board planned for leopard?
  • [18:42:03] <ds2> koen: The mounting on the leopard for the camera irritates me.... the 90deg makes it easy to snap and break things
  • [18:42:24] <khasim> koen: but on leopard DM355 does the processing with ISP, but here we should use DSP For the same
  • [18:42:25] <ds2> koen: there is? or was that talk from me? I been wanting to build on
  • [18:42:39] <AV500> khasim: this is all going the wrong way, please get a TI HW team to us, so we can tell them what chip to make in the 1st place :-)
  • [18:42:55] <koen> ds2: I think Nara or Bill mentioned it
  • [18:42:58] <AV500> then we can discuss the "board" for that chip :-)
  • [18:43:22] <ds2> koen: ah.. I don't think I know either of those folks or heard from them
  • [18:43:24] <khasim> :) it is going reverse
  • [18:43:40] <khasim> koen: knows CEO - 1 to me :)
  • [18:43:41] <AV500> khasim: but dont expect us to get an agreement before 2011
  • [18:43:51] <koen> ds2: nara won is the dm3xx guy at TI and Bill Pu is from leopard imaging
  • [18:44:09] <AV500> khasim: gotto, see you!
  • [18:44:12] <AV500> khasim: gotta go, see you!

  • [18:44:23] <ds2> koen: ah I see. Unfortunately, I am still learning about the DaVinci side
  • [18:44:25] <khasim> AV500: thanks for inputs
  • [18:44:30] <koen> ds2: me too :)
  • [18:44:39] <ds2> hence the strong desire for a Leopard to get going

  • [18:45:26] <pro-rsoft> should I uninstall current linux headers when compiling kernel?

  • [18:45:49] <khasim> koen, but named as OMAP L 138
  • [18:46:01] <koen> khasim: by marketing :)
  • [18:46:06] <ds2> khasim: heh... I had the official DM355 board in my cube last year but never got it
