kristianpauldamn, first boot atemtp with gps clock no data on uart...02:13
kristianpaul81.920 Mhz is the system clock now...02:13

qi-bot[commit] Xiangfu Liu: nanonote-files: config.full_system don't compile atben (master) http://qi-hw.com/p/openwrt-packages/19577b002:24
kristianpaulokay okay, i'll try use PLL instead of DCM to get 80 Mhz from 16.384Mhz clock 02:27

apinkHowdy all.03:52
apinkI am mounting the ubi1 disk space each time at startup. 03:53
apinkIt takes about 8 sec.  to mount, prolonging my startup time.  Is there any way to speed it up.03:53
apinkI use a script as follows:  03:54
apinkubiattach /dev/ubi_ctrl -m 303:54
apinkmount -t ubifs ubi1:home /home/03:54
kristianpaulI guess not much beside do the mount after gmenu2x is running...03:55
kristianpaulI switched to the removable memcard storage because of that actually03:55
kristianpaulgoing bed, see ya03:55
apinkI don't start gmenu2x.  I just run from the shell.03:55
apinkMaybe I will just use the memcard also.  Thanks.03:56
kristianpaulmay be, sorry i dont have more answers03:57
kristianpaul_but_ stay around for a while may be you can get more from other people03:57
xiangfuok. qi-bot is quite. means the compile is continue. 07:11
qi-bot[commit] Werner Almesberger: midi2osc: slight README and Makefile cleanup (master) http://qi-hw.com/p/wernermisc/20283fe07:13
wolfspraulxiangfu: I can play the big buck bunny video from David fine on my Ben08:48
wolfspraulbut when I converted Sintel it doesn't play08:48
wolfspraulI noticed David's file has audio with 44100 hz, 2 ch08:48
wolfspraulwhereas my sintel ogv has 48000 and 6 channels08:48
wolfspraulI will try to re-encode the sintel one with 2 channels @44100, maybe that explains the problem...08:48
C-Keendownsampling in software is expensive08:49
wolfspraulgreat, ffmpeg2theora says "resampling with input channels greater than 2 unsupported"08:50
C-Keendoesn't the dvd have a stereo track also?08:51
wolfspraulah well, indeed09:09
wolfspraulffmpeg2theora cannot resample 6 channels into 209:09
C-Keenalso resampling even 2 channels from 48K to 44.1K is expensive09:10
wolfspraulnice. I updated ffmpeg2thora & ffmpeg and now I get a segfault exactly after "channels 6 -> 2" :-)09:15
wolfspraulI guess that's progress...09:15
wolfspraulfrom 6 to 1 doesn't segfault, let's see whether that plays on my Ben...09:16
wolfspraulhe yes, it plays now but the sound is very strange and crackly09:41
wolfspraulbut looks like I'm on the right track09:42
wpwrakwolfspraul: btw, what do you use to convert my MOVs to OGG ?10:21
mththe NanoNote can play 48 kHz audio, as long as it is 2 channels10:39
wolfspraulI'm close. I have an ogv file without sound, which plays fine. and I have a 2-channel flac sound file. How do I mux the two together?10:40
wolfspraulyes :-) but I never quite can figure out the options, info mencoder is scary10:42
wolfspraulwpwrak: I use ffmpeg2theora10:42
mthyeah, it's always a puzzle to get mencoder to do the right thing, but it can do almost any conversion10:42
wpwrakaah ! let's see ...10:43
wpwrakaptitude thinks there's trouble. hmm. let's see if it can sort this out ..10:44
wpwrakinstallation broke mplayer. now let's see about that. i dislike these blind alleys on the dependency graph.10:50
wpwrakwolfspraul: excellent. factor 40 size reduction :) thanks !11:19
wolfspraulmth: wow I made it ;-) I used mkvmerge to remove the 5.1 audio track and then merge the separately downloaded flac 2ch one back into the mkv container13:34
wolfspraulthen ffmpeg2theora to convert it to 320p width and 44100 hz (just in case) - plays beautifully13:34
wolfspraulwill upload into qi wiki (still experimenting with quality level 5 and 10 to see which one is better)13:35
wolfspraulthanks for your encouragement! :-)13:35
wpwrakwhat did you convert ?13:36
wolfsprauloh, not quite. I only have the music now ;-)13:37
wolfspraulSintel, the Blender Foundation movie after big bucks bunny13:37
wpwrakah ! that may be somthing i haven't heard of yet. checking ..13:40
wpwrakah, now i remember the movie14:18
wpwraksintel, the latest blender foundation movie. with the dragon girl.14:24
vladislavkorotneah i see14:24
wpwrakxiangfu: your question has a very easy answer ;-) http://projects.qi-hardware.com/index.php/p/ben-wpan/source/tree/master/install/INSTALL-PC15:37
wpwraki.e., CONFIG_TUN15:37
xiangfuwpwrak, yI already install the module. 15:38
xiangfureading INSTALL-PC.15:39
xiangfuonly read the INSTALL-Ben :)15:39
xiangfufrom the 'dmesg' it success load 'tun' module. 15:41
xiangfubut 'ifconfig -a' only give 'lo/usb0/wpan0' no 'tun0' :(15:41
wpwrakah, the tun0 is created when you run dirtpan15:42
xiangfuah. correct. maybe I run some command wrong. 15:46
qi-bot[commit] Xiangfu Liu: nanonote-fiels: wpan add command config another ben (master) http://qi-hw.com/p/openwrt-packages/649037a15:47
rjeffriestwo very interesting inexpensive Linux systems will soon be available: BeagleBone $89USD https://www.adafruit.com/products/513 and Raspberry Pi $35USD http://www.raspberrypi.org/16:12
rjeffriesboth are ARM based (what a shocker) and offer different combination of features. No, they do not meet the openess standards of Qi Hardware, but none of use lives by NanoNote or Milkylist alone. ;)16:14
C-Keendo you know about openhardware.org/journal/ ?16:59
