May 14 11:51:02 join #openslug May 14 12:05:45 cbrake, is it a rival channel ?-) May 14 12:06:00 haha May 14 12:06:17 what other nslu2 channels are there ? May 14 12:06:32 * xkr47 checks the wili May 14 12:06:34 wiki* May 14 12:06:37 nslu2-general, openslug May 14 12:06:46 I think there's german one too May 14 12:07:32 waah May 14 12:07:38 "#nslu2-linux - note that end-user questions are not welcome on this channel." May 14 12:07:57 sorry guys! I didn't know! May 14 12:08:30 * xkr47 didn't read the topic obviously :P May 14 12:14:24 sadly enough NAiL isn't there :P May 14 12:36:28 xkr47: not sure what the diff is between openslug and nslu2-linux May 14 12:37:15 no massive difference ... openslug is rarely used these days May 14 12:44:12 the #openslug channel is pretty much ignored; users are encouraged to use either #nslu2-general (for most questions) or #nslu2-linux (for developer topics). May 14 12:47:31 mwester: hallo :) May 14 12:49:32 mornin' May 14 13:27:25 03blaster8 * r840 10kernel/trunk/patches/2.6.21/: Remove 2.6.21 again (it'll be back next revision) May 14 13:42:02 03blaster8 * r841 10kernel/ (238 files in 8 dirs): Everything back in trunk, sigh... May 14 13:47:51 03blaster8 * r842 10kernel/trunk/Makefile: Point Makefile to build a supported kernel May 14 14:43:13 * xkr47 'll see if he can do some BE vs LE comparision with a fresh slugos firmware May 14 16:42:16 Hi. I am trying to build the slugos firmware with the mastermakefile, my problem is that it fails when trying to fetch the mtd-utils source with git. git pull git://git.infradead.org/mtd-utils.git - the error is: git: fatal error: `chdir' failed: permission denied, any suggestions what I can do? :) May 14 16:44:14 With the following command: "make slugosbe-image May 14 16:47:59 codejunky: cloning mtd-utils from the git works for me, could you try performing git-clone git://git.infradead.org/mtd-utils.git ? May 14 16:53:21 Sorry! I had the wrong git installed. :) http://www.gnu.org/software/git/ May 14 16:53:27 Now it is working. May 14 17:04:05 I have now another problem. In task 643 - slugosbe/openembedded/packages/images/slugos-imageb, do_rootfs. May 14 17:04:26 In the logfile is written: install -d /home/jan/slug/slugosbe/tmp/deploy/images/firmupgrade, install: cannot change permissions of `/home/jan/slug/slugosbe/tmp/deploy/images/firmupgrade': Not a directory May 14 17:06:28 ls -l /home/jan/slug/slugosbe/tmp/deploy/images/ shows that it is a directory. May 14 19:24:02 argh, I can hear the power supply of the nslu2 May 14 19:24:29 some high frequency noise May 14 20:03:41 xkr47: that can be tackled with a hardware tweak. May 14 20:24:22 xkr47: sure it's not the flash? May 14 20:25:25 pluesch0r, how? May 14 20:25:28 NAiL, I put my ear to it May 14 20:28:58 yeah May 14 20:29:18 and the device isn't turned on atm.. :) May 14 20:29:31 I noticed my slug started whining (high-pitched and barely audible) when I accessed the flash May 14 20:29:36 wonder if the whining goes away if I turn it on :) May 14 20:29:43 ok May 14 20:30:20 wonder what's a good way to filter high-frequency signal May 14 20:30:35 fabric May 14 20:30:45 foam May 14 20:31:02 ok May 14 20:31:03 bucket of water? May 14 20:31:10 heh May 14 20:31:20 distilled water would work a while ;) May 14 20:31:20 (don't anyone do that, btw!) May 14 20:31:42 Won't mineral oil do it too? May 14 20:32:02 I heard somewhere that someone cooled a way-overclocked CPU with an oil bath... May 14 20:32:09 yeah May 14 20:32:26 well, dunno about the overclocking with oil though May 14 20:32:41 the problem with oil and overclocking is that you need to move the oil a lot May 14 20:32:44 Anyway - xkr47: switching supplies often make noise, not a problem (unless you have sensitive hearing, or keep it close to ear level) May 14 20:33:03 Don't you liquid-cool a system, NAiL? May 14 20:33:18 I know, I often hear camera chargers too.. from 4 meters distance May 14 20:33:33 mwester: not anymore May 14 20:33:37 it sprung a leak ;) May 14 20:33:41 Oops! May 14 20:34:15 oh my May 14 20:34:51 well, it started leaking when I was switching cases May 14 20:34:56 so nothing was harmed May 14 20:35:03 I was just a cooling-system short ;) May 14 20:36:10 * mwester considers the advantages of a SLUG: it's slow performance is faster than a gigantic AMD in a puddle of water ;) :p May 14 20:36:19 so it became a heating system instead ?-) May 14 20:36:31 xkr47: just put it somewhere else. May 14 20:36:43 lol May 14 20:36:56 best hack ever. :) May 14 20:37:17 how much does 5V DC drop over a 10m wire ? May 14 20:37:31 Ohms law May 14 20:37:57 how much ohms should I expect in basic wire :) May 14 20:38:05 0.1 ? May 14 20:38:15 /meter May 14 20:39:29 Hi. I compiled successfully the slugos firmware with the Mastermakefile and burned it to my nslu2. My question is if anybody can give me a hint (maybe some documentation) how I can build a custom kernel. May 14 20:39:45 Or where the kernel sources are in the tree and how I can change the configuration. :) May 14 20:40:31 openembedded/packages/linux/ixp4xx-kernel/ May 14 20:40:39 there should be a defconfig there May 14 20:40:47 Ok, thx. May 14 20:40:47 (somewhere around there, anyway) May 14 20:42:45 gaah, I don't have 10G free to build my custom slugos firmware :O May 14 20:45:57 xkr47: From memory, standard house-class wiring (14 guage) is about 0.5 ohms / 100 ft length. So, if the slug is 50 ft from the PSU May 14 20:46:10 thx :) May 14 20:46:32 THat's 100 total feet of wire, for 1/2 ohm. If you assume it pulls 2.0 amps max, that's 2.0 x 0.5 = 1.0 volts drop (!) May 14 20:47:19 So, at full load, you are probably going to have problems with something as large as 14 guage wire May 14 20:47:41 and 2W of heating also :) May 14 20:47:52 You'll have to find a chart for the larger wire, or shorten up the cable -- the problem is that 2 amps at 5 volts doesn't give you much room for error May 14 20:48:12 I would say that you should target 10% voltage loss as the max May 14 20:48:24 basically I'd need to go with 7V in the other end and add a 7805 or similar in the nslu end May 14 20:48:44 Thanks for the help. Bye. May 14 20:48:47 No - that's would be messy. If you're going to do that, just change supplies outright. May 14 20:48:58 yeah :) May 14 20:49:00 Go with thicker wire, or short length. May 14 20:49:13 I guess a silent 5V / 2A is not that hard to get May 14 20:49:34 although it will generate some more heat :P May 14 20:49:42 I've used the low-voltage landscape lighting wire for project before. May 14 20:49:54 It's well-insultated, goes up to 12 guage May 14 20:50:02 and is very inexpensive May 14 20:50:16 right May 14 20:50:40 haven't really considered pulling dc over long stretches before May 14 20:51:30 That's why Tesla won, and Edison lost! May 14 20:51:39 yeah, I read about that :) May 14 20:51:56 but I guess they used a bit more than 10W's worth of energy :) May 14 20:52:14 nikola had other nice projects too May 14 20:53:06 luckily he didn't go ahead to try to create standing waves in the ground that would spread all over the world and potentially wreak havoc everywhere :) May 14 20:54:01 or set of a few well-placed explosives and split the earth in two ;) May 14 20:54:31 didn't read about that :) May 14 21:23:32 xkr47: You'd need at least 2 7805's. I don't know of any that does more than 1.5A May 14 21:23:56 yeah May 14 21:24:08 Or use a 6v supply. :) May 14 21:24:25 a ľA723 with some power transistor would do too :) May 14 21:30:19 how about the separate 128M conf partition that unslung created, is it needed in openslug ? May 14 21:42:12 xkr47: no, openslug (or SlugOS, preferred nomenclature now) does not require any special partitioning. May 14 21:43:02 strange thing, I unmounted all disks in openslug before running fdisk May 14 21:43:06 Also, don't use a 6v supply: if the slug drops to 0.5 A current draw, the voltage drop in the long cable will be reduced, and the slug may see a voltage rise -- which may lead to overheating. May 14 21:43:31 when I do "w" to write the partition table, it mounts /dev/sda1 automatically before I even got to format it (it happened to start in the same place as the old partition) May 14 21:43:35 Ohms law is a very simple law, but like gravity it has little mercy. May 14 21:43:49 yeah, I won't May 14 21:44:45 That would be udev, I think, that's doing that. Just umount the partition again, and go format it. May 14 21:44:57 yeah.. heh May 14 21:45:12 but it seems the kernel is out of sync because it says May 14 21:45:16 WARNING: Re-reading the partition table failed with error 16: Device or resource busy. May 14 21:45:19 The kernel still uses the old table. May 14 21:45:37 it's mounting it so bloody fast the kernel thinks it shouldn't use the new partition table May 14 21:45:54 that sounds awful.. is it mounted using the new partition table or the old :P May 14 21:46:05 I'll do a reboot :P **** ENDING LOGGING AT Tue May 15 02:59:58 2007
