[09:32:50] <tesla_> hi there, it looks like there're still some people playing around with their zipits :)
[09:33:59] <tesla_> I'm using the rootfs from http://zipit.rootnexus.org/ but it's very old, is their something newer?
[09:48:22] <ang> tesla_, most people seem to be using openwrt now
[09:48:54] <tesla_> ang: is there something built, or a wiki?
[09:51:21] <tesla_> oh, there's a link in the topic, nevermind
[09:51:34] <ang> check mozzwald's webpage, http://www.mozzwald.com
[09:52:15] <ang> or here http://www.chainxor.org/openwrt-zipit/
[09:52:48] <tesla_> great, thanks
[09:53:09] <ang> do you have u-boot on your zipit?
[09:54:04] <tesla_> yes
[09:54:35] <tesla_> is this a problem?
[09:55:36] <tesla_> oh damn, it's not uboot
[09:56:26] <tesla_> i forgot, it's from openzipit autoflasher
[10:00:23] <ang> well, on mozwalds site he has a flasher as well: http://mozzwald.com/node/148
[10:00:30] <ang> i would read up on it first :)
[10:01:41] <tesla_> of course ;)
[10:07:01] *** fiftyonefifty has joined #zipit
[10:08:19] *** fiftyonefifty has quit IRC
[10:19:43] *** slug_ has joined #zipit
[10:21:45] <slug_> mozzwald: add the 'no-rtti' flag to the mplayer makefile --> MAKE_FLAGS = -j4 -no-rtti
[10:24:14] <slug_> I had jack included in my mplayer build, both jack and live are C++ libs, you don't need jack though
[10:27:05] <slug_> walrus45: it sounds like you have a bad SD card
[10:36:37] *** user has joined #zipit
[10:37:15] *** user is now known as _unreal_
[10:37:25] <_unreal_> hello
[10:39:46] *** fiftyonefifty has joined #zipit
[10:59:23] <tesla_> ang: is there somewhere a overview of useful programs for the zipit?
[10:59:38] <tesla_> *useful and working with the screen-resolution
[11:00:26] *** slug_ has quit IRC
[11:01:56] *** _unreal_ has quit IRC
[11:03:25] *** user has joined #zipit
[11:03:44] *** user is now known as _unreal_
[11:03:45] <mozzwald> tesla_: you could check the repo which has a list of the packages. anything in particular that you're looking for?
[11:44:37] *** UnderSampled has joined #zipit
[12:12:22] *** slug_ has joined #zipit
[12:16:27] <mozzwald> slug_: adding no-rtti causes make to go very fast and appears to not actually compile anything.
[12:18:55] <slug_> uh oh... you get a 'can't stat' error?
[12:19:05] <mozzwald> yup
[12:20:22] <tesla_> mozzwald: nothing particular, but i thought i could get some ideas from a list ;)

[12:23:22] *** scottie4442 has quit IRC
[12:26:10] *** anarsoul has quit IRC
[12:41:44] <slug_> mozzwald: I ended up having to remove the --enable-live from the makefile altogether, let mplayer's config find the live includes and libs on it's own
[12:42:13] <slug_> also get rid of the no-rtti flag that I suggested
[12:43:28] <slug_> then I had to have the live libs in the mplayer build dir as well as the staging_dir/target..../usr/lib folder
[12:49:15] <slug_> let me know if you can multicast with the existing kernel, I may need to provide a new one configured with that enabled
[12:53:12] <tesla_> hm... i get "lost page write to i/o error on mmcblk0p1 during boot, what can i do?
[13:13:27] *** deeice has joined #zipit
[13:19:44] <tesla_> anyone got an idea?
[13:21:27] *** slug_ has quit IRC
[13:22:01] *** slug_ has joined #zipit
[13:28:56] <deeice> tesla_: Did you switch to uboot?
[13:29:58] <tesla_> yes
[13:32:10] <tesla_> deeice: why ?
[13:32:12] <deeice> In my experience, after loading uboot, some zipits can no longer use any SD cards, some zipits can work with a few SD cards, and other zipits seem happy with just about any SD card.
[13:32:32] <tesla_> hm...
[13:32:50] <tesla_> so maybe a different sdcard would solve my problem?
[13:33:49] <deeice> maybe. but I have one zipit that will no longer read *any* card, even though some of the cards work in another zipit with identical software.
[13:34:31] <deeice> Some folks have reported better success with cards less than 2gb by well known mfgrs.
[13:35:38] <tesla_> okay, luckily i found some other cards, will try them now. thanks for this info
[13:35:51] <slug_> my cards read ok, but I only have one (of 4) that I can write to on the ZipIt... I can read/write to all of them on the laptop
[13:37:42] <deeice> slug_: I also have a mixed bag of cards with varying levels of success. But then I realized it's not just the cards. Different zipits have varying degrees of trouble with the same cards.
[13:38:00] <slug_> you can format and create images, etc, like walrus45 was doing, but then when you reboot, none of the operations performed on the SD card will be effective
[13:38:18] <tesla_> right, that's excatly the problem i got
[13:38:38] <deeice> Then you may be able to find a magic rw card
[13:38:39] <slug_> deeice: yes, I recall your thoughts that it might be a pin that's not initialized
[13:39:13] <deeice> slug_: That's what I suspect, based on the different zipits.
[13:40:38] <deeice> Maybe someone with lotsa bootloader experience could go over the uboot sources and the zipit blob patches to see if something got skipped.
[13:40:53] <slug_> that sounds really fun
[13:41:21] <deeice> yeah, I'm not gonna do it. :)
[13:44:27] <slug_> although, I've spent enough time reformatting cards that get hosed because of it, one of these days I may break down and start digging
[13:46:00] <tesla_> well, it seems like my 2gb sd is working
[13:46:27] <deeice> I looked once upon a time. I didnt see a whole lot of mmc code changes in the blob zipit patches. But I don't know enough about the interface to do anything with it.
[13:46:45] <tesla_> but now, when i run "wifi" i get operation not support (-95), and i got no idea what it means, google neither
[13:47:04] <deeice> which openwrt?
[13:47:36] <deeice> I like the old wifi support in slug's jffs distro.
[13:48:13] <tesla_> http://www.chainxor.org/openwrt-zipit/ this one
[13:48:57] <deeice> What do you have on your jffs?
[13:50:05] <tesla_> i followed this instruction http://www.mozzwald.com/node/59
[13:50:27] <tesla_> (means: i don't really know :D )
[13:51:11] <deeice> Try this http://blog.engine12.com/?p=460 Then you have something that works with no SD required. You can still boot from the SD if you want..
[13:52:22] <tesla_> okay
[13:53:13] <slug_> tesla_:use this one --> http://engine12.com/files/gmenu-zipit/gmenu_jffs2_rc10.tar.bz2
[13:54:22] <deeice> Is that new? Last I remember was rc9.
[13:55:56] <slug_> deeice: not too new, I need to update the link though
[13:56:13] <deeice> tesla_: You will probably need to tweak the uboot env after loading that. Do you get the correctly rotated uboot prompt?
[13:56:24] <tesla_> http://www.mozzwald.com/node/59
[13:56:44] <tesla_> yes it was correctly rotated
[13:56:55] <tesla_> ignore that link
[13:56:56] <tesla_> :D
[13:56:57] <deeice> slug_: When you update the link don't forget the warning about tweaking the uboot env.
[13:57:49] <slug_> deeice: yeah ok will do, have you tried out an mp3 multicast yet?
[13:58:19] <deeice> tesla_: Then it's probably safe to load the rc10. Check the irc logs a few days back for the uboot env changes you'll need to make. Walrus just ran into it recentlly.
[13:58:59] <tesla_> where are the logs?
[13:59:19] <deeice> slug_: My hearing is bad so I wouldn't know if the multicast was reaching multiple zipits.
[13:59:49] <slug_> deeice: it's still fun to set up though
[13:59:55] <slug_> tesla: http://www.mozzwald.com/irclog/readlog.php?chan=zipit&date=2012-5-05
[14:00:07] <deeice> http://www.mozzwald.com/irclog/calendar.php?&date=2012-5-1&chan=zipit
[14:00:18] <deeice> jinx!
[14:00:39] <slug_> no I think i posted first :)
[14:00:44] <tesla_> thx
[14:01:00] <deeice> At my age those posts appear simultaneous.
[14:03:51] <slug_> it must have been the --enable-yuv4mpeg option, mplayer is now playing the mjpg-streamer output flawlessly, I had rainbows and artifacts on the image before
[14:07:23] <deeice> what's the source of your mjpg stream?
[14:07:35] <tesla_> I'm not sure if found the right changes for uboot env, http://www.mozzwald.com/irclog/readlog.php?chan=zipit&date=2012-5-01 <- right day?
[14:09:31] <slug_> deeice: local server, liveCaster... or I was just using testMP3Streamer, there's plenty of processing power on the Z2 for the tast
[14:10:37] <slug_> tesla_: that's right
[14:11:36] <tesla_> thx
[14:11:39] <slug_> o the mjpg stream... that's a webcam, logitech
[14:12:23] <deeice> is the webcam on another zipit?
[14:13:41] <slug_> yeah, but the zipit need to remain plugged in otherwise the usb drops out, I need to solder in a circuit so the voltage won't drop when I unplug it
[14:14:14] *** _unreal_ has quit IRC
[14:14:36] <slug_> mount it to the lawn mower and start training
[14:14:56] <deeice> yeah, it's about that time of year.
[14:17:33] <deeice> If you add a mic, you could use 2 zipits for video conferencing. http://blog.pjsip.org/2007/09/20/how-to-use-your-nintendo-ds-as-a-phone-and-make-free-calls/
[14:18:30] <slug_> hey cool, I have usb-audio available on the webcam already
[14:18:30] <deeice> oh, wait. the NDS thing looks like it's just audio phone calls.
[14:22:11] <slug_> I was gonna try and get linphone running one of these days too
[14:24:57] <tesla_> hi again ;)
[14:25:05] <deeice> I'd be even cooler if you ditched the webcam and used a small mic on the weird audio connector. Then you could flip open the zipit and put it up to your ear like a real phone.
[14:25:35] <tesla_> first: thats a really nice system, but i seem to have wifi problems again
[14:26:09] <slug_> deeice: that would be neat :)
[14:26:21] <slug_> tesla_: what's the problem?
[14:26:42] <tesla_> it's says it's unable to connect, but i'm sure i used the right passphrase
[14:26:48] <deeice> WPA?
[14:27:01] <tesla_> yep
[14:27:12] <deeice> yeah, slug's gotta fix that...
[14:27:49] <slug_> yeah, sometimes it gets screwed up, maybe try rm /etc/wpa.conf and try again
[14:27:50] <deeice> I could only connect to an open net with that jffs.
[14:28:36] <slug_> I connect np with a password protected wpa ap
[14:28:38] <deeice> I'm not up to date though. maybe on rc5 or so..
[14:29:04] <tesla_> success! :D
[14:29:14] <tesla_> deleting wpa.conf solved it
[14:29:42] <tesla_> maybe it happend when i accidenly pressed connect, when i had enterd nothing
[14:29:45] <deeice> Watch that. I think the older version kept adding to the wpa.conf file every time I connected.
[14:30:20] <slug_> there's something wrong with the 'first time', another solution is to suspend and wakeup, that sometimes does it, of course that process unloads and reloads the drivers too
[14:31:16] <slug_> maybe I'll stop putting a default wpa.conf in the build and see what that does
[14:32:45] <tesla_> so, if i want to install something now, will it install on the sd ?
[14:32:57] <tesla_> sry if thats a stupid question...
[14:33:38] <slug_> you need to use ovpck to install to the sd card
[14:33:52] <slug_> but first you need to make an overlay image
[14:35:00] <tesla_> O_o how :D ?
[14:35:04] <slug_> you need to read mozzwalds site for the details of the overlay system --> http://mozzwald.com/node/161
[14:35:27] <slug_> all the files are in place, etc, just read how to use them
[14:36:17] <deeice> slug_: You should link to that on your page because the first thing people want to do is add more stuff.
[14:36:37] <tesla_> ok, thx
[14:37:57] <slug_> deeice: it is already, there's just alot of other details too
[14:38:28] <tesla_> "to create a 128mb image" can i adjust the image size? i got a 2gb sdcard
[14:39:04] <slug_> yeah, make it whatever size you want, it will take longer to make though
[14:39:31] <tesla_> kk
[14:39:57] <slug_> I geuss I could describe a little more about what the overlay is and group that into a section for intalling new programs
[14:40:08] <tesla_> would be great :)
[14:40:20] <deeice> slug_ yes, the way it's written it's totally unclear that overlay is for adding more stuff.
[14:41:57] <deeice> Hey, the sun's out. Gotta go do some outdoor things...
[14:42:53] <tesla_> mounting the inmage file to /dev/loop0
[14:43:05] <tesla_> losetup: /dev/loop0 no such device or directory
[14:44:28] <slug_> tesla_: you'll have to wait for mozzwald if you need help with that, maybe try again :)
[14:44:59] <tesla_> :(
[14:45:15] <slug_> but if you cant write to the sd card, you won't be able to make an overlay image

[14:53:16] <tesla2> i think my shell is down, did i miss something?
[14:53:44] <slug_> what?
[14:54:29] <tesla2> the last thing i got was: wait for mozzwald
[14:55:03] <slug_> o, I was just saying that if you cant write to the sd card, you won't be able to make an overlay image
[14:55:44] <tesla2> oh, okay. maybe i should try a diffferent card again :D ?
[14:56:27] *** tesla2 has quit IRC
[15:01:42] *** tesla3 has joined #zipit
[15:01:56] <tesla3> that annoying :P
[15:02:07] <tesla3> sry to ask again: what did i miss
[15:03:17] <slug_> you can also check the irc logs --> I was just saying that if you cant write to the sd card, you won't be able to make an overlay image
[15:03:35] <tesla3> okay, this i did get :)
[15:03:58] <tesla3> thanks, didn't think of the logs
[15:04:34] <tesla3> slug_: is the jffs system your work?
[15:07:35] <slug_> the one that you just loaded have been compiled by me, but there is alot of work from all of us included
[15:09:40] <tesla3> i love it. it's fast and makes linux on the zipit really useable :)
