14:08 <****> starox_away : you know how to make to use cross compiler ?
14:10 <****> starox: can u suggest me any solution ??
14:10 <****> sreekanth: I'm not used to openmoko/openembedded stuff.
14:11 <****> oh ok ..
14:12 <****> sreekanth: Tell me which doc you follow .. how did you make your crosscompiler ? And first : file /usr/local/openmoko/arm/bin/arm-angstrom-linux-gnueabi-gcc
14:12 <****> starox: i am following the doc http://wiki.openmoko.org/wiki/Toolchain
14:14 <****> sreekanth: You download the .tar.gz or use bitbake to build your own ?
14:18 <****> I'm pretty sure the cross-compiler is not compiled for your host machine.
14:32 <****> starox: How do i compile it for my machine ?
14:32 <****> i actually downloaded the cross compiler
14:37 <****> how do i compile the cross compiler for my host ?
14:41 <****> sreekanth: It's on the page you gave me : http://wiki.openmoko.org/wiki/Toolchain#Downloading_and_installing
14:42 <****> sreekanth: Have you downloaded the right archive ? what is the output of : file /usr/local/openmoko/arm/bin/arm-angstrom-linux-gnueabi-gcc
14:43 <****> starox: /usr/local/openmoko/arm/bin/arm-angstrom-linux-gnueabi-gcc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not stripped
14:43 <****> and file /bin/ls ?
15:19 * ScaredyCat yawns
15:24 * SpeedEvil sighs and wishes he could buy 32*32 camera modules cheap.
15:26 * ewon too
15:26 <****> one can hack together a high-speed slow motion camera array with that many sensors
15:26 * ScaredyCat blames mickeyl for breaking stuff
15:26 * SpeedEvil wants them for a panoramic camera (360*360) to locate the sun.
15:27 <****> just look up :)
15:27 * SpeedEvil is building a UAV, and may be going overkill on the attitude sensors.
15:27 <****> gps unit?
15:27 <****> diy missile?
15:27 <****> heh
15:27 <****> GPS + 3d accelerometer + 3 axis gyro + sun-sensor + 3 axis magnetometer.
15:27 * ewon awaits the black helicoptors
15:28 <****> +barometer
15:28 <****> I got abused by a british airways hostess for using my gps on the plane
15:28 <****> http://www.interestingprojects.com/cruisemissile/
15:28 <****> ScaredyCat: heh, what did i?
15:28 <****> +do
15:28 <****> ScaredyCat: Bruce what'shisname?
15:29 <****> mickeyl: glib-native-2.0
15:29 <****> SpeedEvil: ya
15:29 <****> ScaredyCat: didn't touch that since ages
15:29 <****> http://www.mauve.plus.com/test.png (quick render)
15:29 <****> it doesn;t exist mickeyl :)
15:29 <****> (of the UAV)
15:30 <****> but it is required for your new openmoko-terminal2
15:30 <****> aah
15:30 <****> not for the terminal
15:30 <****> guess that's introduced by vala-native
15:30 <****> let me check
15:30 <****> ya
15:30 <****> heh
15:30 <****> glib-2.0-native
15:30 <****> vs.
15:30 <****> glib-native-2.0
15:30 <****> ;)
15:30 <****> sorry
15:30 <****> fixing
15:31 <****> :)
15:31 <****> wtf is that SpeedEvil!
15:31 <****> ScaredyCat: it's a UAV optimised for taking pictures at altitude. The nacelles have battery, camera, computer in.
15:32 <****> sweet... for a diy goole earch type thing ?
15:32 <****> earth
15:32 <****> That's the idea. Well.
15:32 <****> To sell them.
15:32 <****> estimated cost? (consumer)
15:33 <****> I'm unsure.
15:33 <****> V0 would be about 400 quid.
15:33 <****> ok, no not like 4k then :)
15:33 <****> But that's probably overkill dramatically on the required stuff.
15:33 <****> k.. so sub 250 after a bit then
15:34 <****> ?
15:34 <****> It depends.
15:34 <****> At the moment it's about a kilo.
15:34 <****> Much of that is due to using an off-the-shelf digicam.
15:34 <****> ouch
15:35 <****> It could shrink down to easily half that, and become better aerodynamically with a custom camera.
15:35 <****> But that gets expensive.
15:36 <****> I guess the problem is that the picture quality needs to be good otherwise it's pointless
15:36 <****> It's a tradeoff.
15:36 <****> A) aim for pure altitude and take great pics.
15:36 <****> B) poorer pics lower to the ground, but lots of them. This means increased loiter time.
15:39 <****> B) also implies wings or fuel power not battery.
15:39 <****> which means either horizontal landing, which is nasty and dangerous, or maintainance issues.
15:40 <****> have you seen those quad hover thingys?
15:40 <****> yes.
15:41 <****>500 launches without issues.
15:52 <****> speedEvil: are you using the OM to control a camera enabled UAV?
15:52 <****> magellan: no.
15:52 <****> magellan: unless I got a board from a partially functioning phone free
15:53 <****> oh so the above isn't associated with OM, I didn't read all of it
15:53 <****> The full phone is a bit too heavy.
15:53 <****> what are you using to control the plane and camera
15:53 <****> I see
15:54 <****> sounds like fun though
15:55 <****> probably tincantools.com 's thingy.
15:55 <****> and lots of sensors
15:56 <****> Im still struggeling with my usb issues
15:56 <****> were you trying to put it in host mode?
15:57 <****> I got the Host patch in there but now I have to get the driver in the kernel
15:57 <****> yes
15:57 <****> I'd try finding where the mokomakefle puts the kernel source code, then patch there.
15:58 <****> then run a nomrmal make openmoko-devel-image and install teh kernel
15:58 <****> kernel/rootfs
15:59 <****><
