Thanks!!. I'm thinking create a little web server like sheevaplug... do you know if beagleboard performance is good?
- [00:06:26] <GeniusGeeko>
It is good enough for a personal server.
- [00:08:01] <testuser>
ok. let's say, enough to work 24x7 ....
- [00:09:41] <GeniusGeeko>
For sure, it is also very energy efficient. Roughly 2-3 watts.
- [00:11:12] <djlewis>
lets get GeniusGeeko on the sales team ;)
- [00:11:36] <testuser>
hehe
- [00:12:23] <testuser>
GeniusGeeko: interesting!!...
- [00:12:31] <GeniusGeeko>
I am used to giving speeches, so that would go very well. XD
- [00:13:33] <GeniusGeeko>
I just need to get this dang bluetooth to work
- [00:15:43] <testuser>
bluetooth doesn't works?
- [00:15:56] <GeniusGeeko>
It does, with a hub, I just need it to work without it.
- [00:17:27] <GeniusGeeko>
It doesn't work because, with the C4 the EHCI usb port only supports high speed devices. Bluetooth doesn't classify for some reason.
- [00:20:31] <testuser>
uhmm sounds difficult. :)
- [00:21:12] <GeniusGeeko>
I'm out of ideas, for right now.
- [00:29:41] * florian (~fuchs@Maemo/community/contributor/florian) Quit (Quit: Verlassend)
- [00:35:26] <GeniusGeeko>
Alright, it actually might involve the powering of the EHCI
- [00:36:01] <GeniusGeeko>
I'll get back to it with the details
- [00:37:59] <GeniusGeeko>
Alright the usb port only works if I plug in the usb hub when I power it up.
- [00:40:12] <djlewis>
GeniusGeeko: get a XM, its hub is three speed

I don't have the budget for it.
- [00:54:28] <GeniusGeeko>
I got $130 left in the budget
- [00:55:00] <djlewis>
yep, i do understand the "budget".
- [00:55:48] <GeniusGeeko>
Haha, it doesn't help that I just turned 16.

djlewis: would powering the bluetooth externally work?
- [00:58:17] <djlewis>
its not a power issue if you are connecting a low speed device to a hi speed port
- [00:58:48] <djlewis>
you running a linux desktop?
- [00:59:11] <djlewis>
if so, lsusb and get the particulars of the device when it sorks
- [00:59:19] <djlewis>
s/sorks/works
- [00:59:33] <djlewis>
to determine if it is 1.1 or 2.x
- [01:04:21] <GeniusGeeko>
I'l have to reboot into linux
- [01:29:20] <djlewis>
GeniusGeeko: you are powering your c4 with a wal wart?

- [02:01:12] <djlewis>

- [02:03:03] <djlewis>
if you are powering through the otg port you might get enough current on the ehci

- [02:56:35] <cmwslw>
if I have the USB OTG plugged into my computer, how am i supposed to communicate with the beagleboard?
- [02:56:42] <cmwslw>
is it a simple usb-serial adapter that shows up as /dev/ttyUSB0?
- [02:57:46] <GeniusGeeko>
I believe it should if you installed the modules
- [02:59:56] <cmwslw>
what modules?
- [03:01:02] <GeniusGeeko>
did you install angstrom?
- [03:01:06] <GeniusGeeko>
or what did you install?
- [03:03:50] <cmwslw>
i have the angstrom demo on there right now
- [03:04:05] <cmwslw>
normally, attaching the otg causes a kernel panic

wait you got it to boot with the otg?
- [03:13:45] <cmwslw>
nope, i have to boot with the 5v first then attach the otg
- [03:13:57] <cmwslw>
idk if its possible to boot with only the otg
- [03:15:28] <GeniusGeeko>
It is, I'm pretty sure.. alright from the demo files there should be a modules.tgz move the contents of it to the root directory
- [03:16:01] <cmwslw>

- [04:11:05] <djlewis>
max power is tolerable
- [04:12:08] <djlewis>

if i had a camera i could get it to track people
- [04:25:32] <djlewis>
thats cheaper than the kit from lynxmotion.com. I have it on my Bot
- [04:25:48] <GeniusGeeko>
I would use a kinect its more acurate ;)
- [04:25:54] <djlewis>
the linxmotion one
- [04:26:20] <djlewis>
get the usb nerf gun
- [04:26:35] <djlewis>
great for cubicle wars.
- [04:28:46] * otubo is now known as otubo[AFK]
- [04:28:50] <djlewis>

- [04:30:03] <djlewis>
what does dmesg tell yo about it?

hello
- [09:14:04] <ericb2>
just for say I received my beagleboard. Thanks a lot to DigiKey guys, was very fast
- [09:16:40] <mbonnin>
ericb2: faster than selectronic :-)
- [09:18:02] <dm8tbr>
and faster than a pandaboard
- [09:18:31] <mbonnin>
pands are slow, eat too much bamboo :-)
- [09:19:09] <ericb2>
mbonnin: ;-)
- [09:19:46] <EricJ>
So me and a friend are having a discussion.
- [09:19:55] <EricJ>
Can some beagleboard play HD video yet?
- [09:20:10] <av500>
depends
- [09:20:24] <dm8tbr>
the SoC can, you need the right codecs :)
- [09:20:41] <EricJ>
"summer of code"?
- [09:20:46] <av500>
the 3630 *can* play H264 HD 720p at 3.1
- [09:20:50] <dm8tbr>
System on a Chip
- [09:20:54] <EricJ>
Oh
- [09:21:04] <av500>
HP, L3.1
- [09:21:16] <av500>
but the codec to do that is not "free"
- [09:21:24] <EricJ>
Hm. Quite impressive regardless.

Guest99362: talk to TI
- [10:27:10] * Guest94419 is now known as ogra_
- [10:27:18] <av500>
you can get an evm or a zoom3 with a HS chip that enables that
- [10:27:30] <av500>
after your sign NDA and pay $$$
- [10:27:38] <Guest99362>
oh...
- [10:27:47] <Guest99362>
zoom3 ...never heard of that
- [10:28:13] <av500>
its the zoom2 with the 36xx cpu
- [10:28:24] <av500>
you can upgrade a zoom2 to zoom3

where can I find info on zoom3?

internet?

s/and with is/and what is/

ericb2: http://www.sakoman.com/OMAP/microsd-card-perfomance-test-results.html

hi, a little question regarding DSS, pck is always integer multiplied from fck right?
- [13:55:07] <mru>
pck is fck divided by an integer
- [13:55:24] <gustavoz>
mru: k thanks, so no 800x600 -> 1024x768 scaling then unless i overclock fck :)
- [13:55:39] <mru>
where do you get that from?
- [13:55:44] <gustavoz>
since pck ~ 65 mhz for a 1024x768 panel
- [13:55:56] <mru>
that's no problem
- [13:56:02] <mru>
fck goes up to 173MHz
- [13:56:08] <gustavoz>
omapdss DISPC error: failed to set up scaling, required fclk rate = 157988568 Hz, current fclk rate = 123428570 Hz
- [13:57:11] <mru>
do you have CONFIG_OMAP2_DSS_USE_DSI_PLL enabled in your kernel config?
- [13:58:04] <gustavoz>
oh no, got DSI disabled in general :)
- [13:58:25] <mru>
enable that
- [13:58:35] <gustavoz>
the panel isn't DSI
- [13:58:39] <mru>
doesn't matter
- [13:58:48] <gustavoz>
oh confusing option, confusing :) thanks!
- [13:58:55] <mru>
you need to use the PLL in the DSI block to get the correct fclk
- [13:59:01] <woglinde>
even its called OMAP2
- [13:59:06] <woglinde>
thats confusing enough

gustavoz: dss sets the frequencies by its own. you have a quite high pck, that's why it doesn't work. 65*3=195, which is already over the limit, so you can only get *2, which is not enough for many scaling cases.

why luck?

expensive and 'future' products vs inexpensive and great 'available now'
- [16:38:16] <av500>
like what moto did on the milestone
- [16:38:35] <pupnik_>
1ghz 40nm omap3 on the a70s is very fast and power sipping
- [16:38:53] <muriani>
prpplague: oh I don't doubt it. Cortex-A9 based chipsets in general are starting to pop into things, and they're very nice.
- [16:39:22] <pupnik_>
i'll consider omap4 in 2012 maybe
- [16:39:32] <av500>
if you can still buy one
- [16:39:50] <prpplague>
av500: agreed
- [16:39:54] <muriani>
I was thinking about converting my old thinkpad to omap4
- [16:40:05] <av500>
with pixie dust?
- [16:40:10] <muriani>
basically just using it as a case
- [16:40:27] <muriani>
would have to interface or just replmace the screen, keyboard, etc
- [16:40:31] <prpplague>
muriani: i've done two netbooks, not too bad
- [16:40:33] <muriani>
the battery should last it awhile though :)
- [16:40:44] <prpplague>
muriani: only problem is the touchpad, most are ps2 interface
- [16:40:48] <muriani>
yeah
- [16:41:08] <muriani>
mine's a clitmouse, not touchpad. Should still be ps2 most likely
- [16:41:25] <av500>
ps2 2 usb is simple
- [16:41:25] <muriani>
I'd likely just replace the lot with a USB-based setup

if any of you figure out how to get the thinkpad trackpoint working as a mouse (usb) i would be so happy to read about it
- [16:48:48] <muriani>
pupnik_: the eraserhead mouse?
- [16:48:51] <pupnik_>
yea
- [16:48:58] <muriani>
yeah, that's what I've got
- [16:49:08] <muriani>
I'd be interested as well.
- [16:49:24] <pupnik_>
well, they sell them as seperate keyboards for not too much money
- [16:49:37] <muriani>
right
- [16:50:01] <muriani>
if I didn't find anything, I was just gonna shoehorn a mini keyboard+touchpad in

http://www.directron.com/ack540bkusb.html
- [16:50:23] <muriani>
something along those lines

that is very well done
- [16:51:36] <muriani>
we keep a couple of those here at the tech bench at work
- [16:51:43] <muriani>
easy plug in and go
- [16:51:57] <muriani>
they're a little janky on some machines though
- [16:52:08] <muriani>
either the touchpad won't work, or works erratically

- [17:09:58] <av500>
prpplague: so you drove the trackpoint from the avr?

ok
- [17:10:25] <muriani>
that's easy enough to work with, then
- [17:10:26] <prpplague>
av500: then the avr talked to the omap via spi

prpplague: that isn'tof interest, but people just want to use their 5v-stuff they already have. I think most wouldn't have bought a bb if they had read the small print ;)
- [18:15:16] <djlewis_>
yep, that 1.8v is a eye opener
- [18:15:29] <djlewis_>
where it comes to interfacint to obsolete ttl
- [18:15:47] <prpplague>
aholler: "that isn'tof interest"? the TI part would do the same thing as the 8745, just all on one chip
- [18:15:48] <av500>
its obsolete for a reason :)
- [18:16:06] <prpplague>
av500: only obsolete for mobile devices
- [18:16:15] <av500>
prpplague: I know :)
- [18:16:24] <aholler>
prpplague: sure, I meant people don't care what is used to level-shift those 1.8v
- [18:16:30] <av500>
I would agree on putting the 3v/5v stuff :)
- [18:16:38] <prpplague>
aholler: understood, but TI does, hehe
- [18:16:49] <av500>
thing is, can it do that for all pinmux usages?
- [18:16:49] <aholler>
I tons of 5v-stuff around i want to use.

i want to use 2.6.25.14 kernel so how to know that this kernel doesnt need inital ram disk
- [19:03:56] <aditya>
is it in our hands
- [19:04:03] <av500>
2.6.25?
- [19:04:07] <aditya>
whether to make use of ramdisk or not
- [19:05:10] <aditya>
ok we have already made some basic tests with that kernel in x86 platform
- [19:05:32] <aditya>
so right now we dont want to change
- [19:05:47] <av500>
who is "we"?
- [19:05:56] <aditya>
me my parter
- [19:05:59] <aholler>
bacause that kernel works on x86? pretty senseless ;)
- [19:06:53] <aditya>
means i couldnt get u
- [19:07:01] <aditya>
senseless >............?
- [19:07:12] <av500>
aditya: why 2.6.25.14?
- [19:07:19] <av500>
where is this kernel even from?
- [19:07:35] <aholler>
you have to use a kernel which supports your hardware
- [19:07:49] <av500>
and, most important, did you visit www.beagleboard.org and read *everything* on it?

so thats y i dont want to go for new kernel
- [19:10:31] <aditya>
and test there again
- [19:10:53] <av500>
well, then backport all the omap3 and beagleboard stuff back to 2.6.25
- [19:12:07] <aditya>
so u mean beagle board doesnt support that kernel
- [19:12:11] <aditya>
is it so
- [19:12:15] <rcn-ee_at_work>
'old'
- [19:12:52] <av500>
aditya: the beagle board is hardware, it does not care what you run on it
- [19:14:42] <aditya>
due to some time constraints i have to go with this old kernel
- [19:14:52] <aditya>
i will go with latest kernel
- [19:15:01] <aditya>
when i m sucess with this
- [19:15:20] <av500>
time constraints?
- [19:17:45] <aditya>
ok actually I doing a project
- [19:18:39] <aditya>
so i m not taking care about kernel version right now
- [19:19:10] <aditya>
if some thing work on old kernel will also work on new
- [19:19:20] <av500>
maybe
- [19:20:25] <aditya>
so i got stucked at uboot
- [19:20:57] <av500>
aditya: why not start with a known good kernel for the BB and add your drivers there?
- [19:21:07] <aditya>
ok
- [19:21:17] <aditya>
suggest
- [19:21:25] <aditya>

you don't netinstall when you have downloaded a complete image

is it in there?

maybe I'm wrong :)
- [22:51:09] <djlewis_>
it is a sad thing that labels can not be trusted
- [22:51:36] <djlewis_>
it means the supply should produce 5vDC at 2Amps draw.
- [22:51:49] <djlewis_>
It may be starting from 12vDC at less current draw
- [22:52:28] <djlewis_>
Always measure a power supply. only takes a second to fry silicon.

I'll get a voltmeter to the neighbor

how did you decide it was 8vDC?

it was an example / supposition

hmmm
