Jun 25 08:06:14 heh Jun 25 08:08:11 yet another hit and run Jun 25 08:15:39 hello i was trying to build a small linux foot print for my beagle board xm, unfortunately etherenet interface is not showing in ifconfig Jun 25 08:15:43 any inputs plz Jun 25 08:15:56 i was using buildroot Jun 25 08:17:21 pastebin the boot log Jun 25 08:17:58 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 3.9.6 (sajjan@ubuntu) (gcc version 4.7.3 (Buildroo3 [ 0.000000] CPU: ARMv7 Processor [413fc082] revision 2 (ARMv7), cr=10c53c7d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instructie [ 0.000000] Machine: OMAP3 Beagle Board [ 0.000000] cma: CMA: reserved 16 Jun 25 08:18:22 pastebin! Jun 25 08:18:24 not paste Jun 25 08:18:28 i mean i compiled kernel with make omap2plus_defconfig Jun 25 08:20:30 http://pastebin.com/ak1S67Bu Jun 25 08:21:27 any idea plz Jun 25 08:21:34 no USB Jun 25 08:21:37 thus no ETH Jun 25 08:21:47 how to enable it Jun 25 08:22:39 its a beagle board-xm re b board Jun 25 08:22:59 there are example uEnv.txt files on the google groups Jun 25 08:23:53 is it uboot enviornment variables? Jun 25 08:25:44 yeah it configures the usb device as an eth interface Jun 25 08:25:49 i cant find an example yet Jun 25 08:25:52 m_billybob: how does that help with USN in the kernel? Jun 25 08:26:00 USB Jun 25 08:26:11 any example plz Jun 25 08:26:12 sajjan: why not use the Beagleboard kernel Jun 25 08:26:16 that is know to work Jun 25 08:26:27 the one that comes with the default Angstrom Jun 25 08:26:42 i just need to recompile the main stream Jun 25 08:26:42 av500 been my experience that uboot interfaces persist Jun 25 08:27:04 billy any examples Jun 25 08:27:16 i know there are im still looking Jun 25 08:27:44 m_billybob: ??? Jun 25 08:28:33 thanks Jun 25 08:29:50 av500 for instance in my case, Ive been having network issues because my uboot eth device persists after im booted Jun 25 08:30:08 what??? Jun 25 08:30:36 yeap Jun 25 08:30:45 i have to manuall set a gateway route Jun 25 08:32:04 i can not use dhcp in /etc/network/interfaces, because "eth0 is not up" yet it is up, and has an ip on the network already. just no gateway set Jun 25 08:32:33 but that's not "your uboot eth device" surely? Jun 25 08:33:09 guys my problem i am not even seeing my eth0 interface after compi,ing new kernel from buildroot Jun 25 08:33:11 I mean, surely, the uboot-specific eth driver is not something the kernel could use? Jun 25 08:33:20 i also doubt that Jun 25 08:33:23 if debian thinks eth0 is down, and ifcnfig shows eth0 is up with an ip. what else could it be ? Jun 25 08:34:02 sajjan: did you forget to include the eth driver, or compiled it as module and it doesn't get loaded? Jun 25 08:34:18 sajjan: AFAIK I had ethernet working in buildroot Jun 25 08:34:46 let me see, if it is module it should be there in /lib/modules of my file system Jun 25 08:34:52 sajjan: you have no USB Jun 25 08:34:56 ETH is on USB Jun 25 08:34:59 no USB, no ETH Jun 25 08:35:10 its beagle board-xm Jun 25 08:35:15 you have no logs with EHCI at all Jun 25 08:35:19 I know what it is Jun 25 08:35:33 compiled it will make ompa2plus_defconfig Jun 25 08:35:37 ye3s Jun 25 08:35:39 yes Jun 25 08:35:47 you mean default config will not enable it Jun 25 08:35:48 ? Jun 25 08:36:00 I have no idea what default config does Jun 25 08:36:08 I would use the beaglebone kernel Jun 25 08:37:04 you can of course also debug mainline omap2plus_defconfig Jun 25 08:37:05 hmm i am totally confused now Jun 25 08:37:28 np: genesis - the land of confusion Jun 25 08:37:39 sajjan, you are using usb wifi ? Jun 25 08:38:05 KotH: i'd rather go for the disturbed version of it. Jun 25 08:38:23 yes Jun 25 08:38:35 i was trying both ethernet + wifi Jun 25 08:38:41 m_billybob: no, usb ethernet Jun 25 08:39:00 yeah atleast usb ethernet Jun 25 08:39:09 sajjan: your kernel does not seem to have USB enabled for the XM Jun 25 08:39:16 use the beagleboard kernel, it has Jun 25 08:39:25 or debug the one you have Jun 25 08:39:47 debug, any idea how it would be..let me see Jun 25 08:39:58 look at the config Jun 25 08:39:58 any main stream beagleboard distribution Jun 25 08:40:05 angstrom Jun 25 08:40:10 now i am using 3.9.6 Jun 25 08:40:27 i mean with latest kernel,i just need a small box with busybox Jun 25 08:40:30 no distributions Jun 25 08:42:18 so? Jun 25 08:42:27 that still allows you to use the angstrom kernel Jun 25 08:42:32 kernel != distribution Jun 25 08:43:52 yup, you mean to say only kernel..but modules also should be inline with kernel version Jun 25 08:44:06 sure Jun 25 08:44:14 my rootfs may be in busybox Jun 25 08:44:14 when you build a kernel, you can build modules too Jun 25 08:44:21 ok Jun 25 08:44:25 understood Jun 25 08:44:34 i feel like i would rather go for it Jun 25 08:44:36 or you can steal kernel + modules from an agstrom imaghe Jun 25 08:44:36 thatts better Jun 25 08:44:42 prebuilt Jun 25 08:44:44 :) Jun 25 08:46:28 ok guys thank you very much Jun 25 08:46:37 will close this thank you av500 Jun 25 08:53:57 av500, are you good with device tree ? Jun 25 08:54:02 http://pastebin.com/RNNXhMcd Jun 25 08:54:18 wondering if that is doable and if so is it smart Jun 25 08:56:49 not good at all Jun 25 08:57:16 default-state = "off"; ? Jun 25 08:57:58 panto: git@github.com:joelagnel/linux-kernel.git (branch dma-devel-mmc2) Jun 25 08:58:13 ^^ the actual am335x DMA devel branch (finally_ Jun 25 09:04:15 heh Jun 25 09:04:26 jackmitchell, sorry didn't have time to look at it yesterday Jun 25 09:04:32 did it worked? Jun 25 09:05:02 hmm what is the DMA bringing in? Jun 25 09:06:25 panto: this is a different branch that joel posted this morning Jun 25 09:06:33 just fetching and will build + test Jun 25 09:06:37 ok, thanks Jun 25 09:06:43 * panto promises to look at it today Jun 25 09:07:28 it's got a fix for the mmc hwmod thats going to go into tony lindgrens branch soon; which fixes the 'Waiting for root /dev/mmc.....' error Jun 25 09:08:17 so, we may have a mainline for-next branch ready to be merged and bootable over mmc on the bone \o/ Jun 25 09:08:38 indeed Jun 25 09:09:20 vaizki: what do you mean? Jun 25 09:09:31 ok, afk for a bit Jun 25 09:10:19 the DMA brings in the DMA, which allows other things to be enabled; fast transfers over DMA for example; and the mmc driver currently requires DMA so it brings in support from the mmc port Jun 25 09:12:07 bah have to buy torque wrenches Jun 25 09:12:08 :\ Jun 25 09:12:15 dealing with suspension Jun 25 09:12:19 dont want to fuck it up Jun 25 09:12:20 lol Jun 25 09:14:16 jack, oh so the current kernel doesn't really have DMA support? didn't know that Jun 25 09:14:33 then again I have been a BB(B) owner for less than a week... Jun 25 09:14:50 vaizki: koens 3.8 kernel has DMA support, but the mainline Linux kernel (until the past few days) didn't have DMA support Jun 25 09:15:05 got it Jun 25 09:15:13 jackmitchell: so it means you're closer to integrating bb support into mainline? cool! Jun 25 09:15:48 I'm still wondering if I could force the BBB to boot from USB by configuring the boot pins Jun 25 09:16:04 kfoltman: me personally no, I just follow the progress and help where I can; but the bb is slowly gaining more features in mainline; it has been able to boot over nfs for a while Jun 25 09:16:52 I'm working on a solar powered data collector for a remote location and I would prefer to have any reflashing done by hamfisted fishermen (really) to happen via a USB port and push button on the outside of a case instead of opening up the thing and putting in micro sd Jun 25 09:17:59 vaizki: why not just make it part of the bootloader or something? Jun 25 09:18:08 on emmc Jun 25 09:18:15 you mean part of the uboot script? Jun 25 09:18:19 yes Jun 25 09:18:24 +/- customized uboot Jun 25 09:18:47 I recall booting over USB using stock uboot Jun 25 09:18:49 well yes but I'm kinda EXPECTING the eMMC to get corrupted at some point when working off such an unstable power as solar in midwinter Jun 25 09:18:51 gahh. Jun 25 09:19:08 well, i pulled my macbook apart because i thouht the track pad was faulty Jun 25 09:19:09 :-( Jun 25 09:19:16 turns out it has been wet Jun 25 09:19:22 and there is corrosion all through it Jun 25 09:19:35 ouch Jun 25 09:19:36 mrpackethead: replaceable? Jun 25 09:19:51 i'd say its a new machine time Jun 25 09:19:59 sell the old one for parts Jun 25 09:20:14 kfoltman, ive been wondering for a while now if you can use USB eth ( on the bbb ) like what is done on the XM. but i do not see any USB options like that in the uboot headerfile i was looking at before Jun 25 09:20:32 m_billybob: usb eth??? Jun 25 09:20:37 ah Jun 25 09:20:39 the otg one? Jun 25 09:20:50 sorry, never tried it Jun 25 09:20:52 I don't think BBB has OTG support Jun 25 09:21:18 i dotn know much about the XM but ive seen some uenv.txt files that seem to indicate people were booting from USB eth Jun 25 09:21:24 vaizki: well, I'm not sure about otg, but there's one device port that can act as a fake ethernet gadget Jun 25 09:21:35 I couldn't boot from regular ethernet using tftp Jun 25 09:21:46 sure but it's in client mode and not a host port Jun 25 09:21:46 on the bbb ? Jun 25 09:21:47 spend like half a day, didn't get a single connection Jun 25 09:21:51 m_billybob: yep Jun 25 09:22:01 kfoltman i wrote a couple of how to's . .. Jun 25 09:22:11 im booting pxe now Jun 25 09:22:15 m_billybob: cool! Jun 25 09:22:24 m_billybob: I'll ask you for the urls later (I'm at work) Jun 25 09:22:33 vaizki: but is it because it's configured as device or because it's a device-only HW? Jun 25 09:22:44 anyway, I should just look it up, sorry Jun 25 09:22:56 kfoltman anyway you can mail them to yourself ? Jun 25 09:23:04 or can i mail them to you ? Jun 25 09:23:26 www.embeddedhobbyist.com can you remember that ? Jun 25 09:23:26 m_billybob: you can mail to wdev@foltman.com if that's not a lot of hassle Jun 25 09:23:30 ok Jun 25 09:23:34 kfoltman: I think it's a hw limitation but I'm just trusting someone else who told a third guy to forget it Jun 25 09:23:35 I'll mail it :) Jun 25 09:23:56 http://www.embeddedhobbyist.com/ Jun 25 09:24:19 ( in case i misspelled it ) Jun 25 09:25:07 kfoltman but ah those are debian based, maybe you could warp to work with angstrom if you're into angstrom Jun 25 09:26:13 m_billybob: the goal was to boot buildroot or something, I think I'll figure it out once I get the connection in first place :) Jun 25 09:26:25 Idont know much about the build steps or default config for menuconfig with angstrom Jun 25 09:26:54 that's not a problem Jun 25 09:26:56 id imagine it might be similar ? all the nfs stuff was enabled by default for the steps i folowed Jun 25 09:26:59 ok cool Jun 25 09:27:17 a problem is that none of my desktops have nfs enabled in kernel, but that's not hard to fix :) Jun 25 09:27:42 good then you may just know more about it than me lol Jun 25 09:28:03 the key is getting uenv.txt right Jun 25 09:28:37 yes, that's the bit I couldn't get right :) Jun 25 09:29:16 my nfs server is actually a virtual machine Jun 25 09:29:32 pita to setup but i finally got it working Jun 25 09:30:28 had my second laptop doing nfs / iscsi /home but i really didnt want to run a second machine just for that Jun 25 09:32:02 does anyone have the datasheet for the eMMC btw? Jun 25 09:32:46 if I could write protect parts of it for example, that would increase confidence in just putting a uboot environment for usb flashing Jun 25 09:35:06 or is the e.MMC much more resistant to corruption in power loss situations than sd cards? Jun 25 09:36:40 hmmm interesting, it can boot also from SPI0 Jun 25 09:36:50 i think the ds for the emmc is NDA limited Jun 25 09:37:27 yea well I read everywhere that BBB is truly open and RasPi is so closed and now I can't find a DS for a part on the BBB ;) Jun 25 09:37:56 and no I don't want to get into an NDA with Micron Jun 25 09:37:57 the controller manufacturer has to hide that his ECC/WL code sucks ... usually Jun 25 09:37:58 well Gerald has no control over what Crucial / Micron does. Jun 25 09:38:58 vaizki: write protect doesn't help if in case of interference from neighbour cells causing bit reversals Jun 25 09:39:13 *-if Jun 25 09:39:45 yea.. what about booting from a SPI EEPROM? Jun 25 09:40:12 uboot has support for booting from SPI serial flash but any idea how the CPU boots from SPI? Jun 25 09:40:24 its in the TRM Jun 25 09:40:37 i glossed over it a couple weeks ago Jun 25 09:40:54 but, EEPROM? like, really? Jun 25 09:41:10 no need for a uEnv.txt file then ;) Jun 25 09:41:16 kfoltman: probably spi flash Jun 25 09:41:26 ah Jun 25 09:41:27 kfoltman: i havent seen an spi eeprom in ages Jun 25 09:41:56 well I just say eeprom because the uboot command to grab stuff from SPI flash is "eeprom read" :) Jun 25 09:43:35 billybob, you mean the AM3359 TRM? Jun 25 09:44:00 believe in no other TRM! Jun 25 09:45:17 ok found it.. see I'm new at this.. ffffuuu... 4161 pages Jun 25 09:45:22 spruh73h Jun 25 09:45:29 or Jun 25 09:45:31 spruh73c Jun 25 09:45:45 yeah its rather large Jun 25 09:47:58 be glad it's large. other companies, who scale freely, do not put half the info into the TRM you'd need to ge the thing working Jun 25 09:49:43 yea sure information is good Jun 25 09:55:42 ok SPI flash boot.. possible but a bit of a hassle Jun 25 10:03:29 KotH: so you'd advise against getting a wandboard? Jun 25 10:04:47 kfoltman: as usual: check kernel support prior to getting anything Jun 25 10:05:25 kfoltman: 1y ago, the i.mx23 support was about "loads kernel" Jun 25 10:05:28 kfoltman: it got better Jun 25 10:05:49 kfoltman: i.mx6* is a different arch, dunno how good the support is Jun 25 10:05:56 "loads kernel and starts it"? Jun 25 10:06:40 av500: if you threatened to beat it with a Ti launchpad, yes Jun 25 10:07:12 that's not a very serious threat? Jun 25 10:10:04 back Jun 25 10:14:07 panto: those branches were useless, I tried dma-devel-mmc, dma-devel-mmc2 and tony lindgrens omap-for-3.11/cleanups; all failed on the 'Waiting for root' error. All I can suggest is give it another day or two and hope that it gets sorted Jun 25 10:15:14 panto: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg91130.html Jun 25 10:15:47 jackmitchell, the sordid mess Jun 25 10:15:47 that's the thread I was using which had me convinced that would be the winning branch Jun 25 10:16:03 don't bet on it Jun 25 10:16:43 panto: I looked at Tony's branch, and the hwmod parts seem to never have been applied for mmc, only the IRQ changes; so I don't know wtf is going on Jun 25 10:16:56 jackmitchell, let me look at it Jun 25 10:17:02 it never works Jun 25 10:17:11 always needs something or another Jun 25 10:20:25 hallo, welchen chip würden sie empfehlen, um von usb nach uart zu übersetzen? FTDI? Jun 25 10:21:01 Sebastian: most english speaking people here recommend ftdi, yes. Jun 25 10:21:23 sorry Jun 25 10:21:23 most german-speaking too Jun 25 10:21:23 hello, what chip would recommend it to translate from usb to uart? FTDI? Jun 25 10:21:43 mru: hrhr Jun 25 10:21:45 indeed. Jun 25 10:21:56 still FTDI Jun 25 10:21:57 lachen heraus laut Jun 25 10:22:21 we understand german here Jun 25 10:23:17 ok, vielen dank... ok, many thanks... Jun 25 10:23:23 but do you understand Germans? Jun 25 10:23:36 ja verstehe ich Jun 25 10:25:02 my ancestors claim that this is impossible. Jun 25 10:25:20 * mru concurs Jun 25 10:25:24 does the ftdi chip handle translating from English to German? Jun 25 10:25:46 Crofton|work: probably, if placed properly on the language barrier Jun 25 10:26:14 also, can one bitbang french? Jun 25 10:26:27 av500: bang french bits? Jun 25 10:26:35 av500: or rather bang frenchs a bit? Jun 25 10:26:59 av500: or even bang bits the french way? Jun 25 10:27:08 LetoThe2nd: I see the re-educatiuon camp did nothing to you Jun 25 10:27:20 av500: hell yeah Jun 25 10:27:45 hm, does french bitbanging take care of the MSB<->LSB issues? ;) Jun 25 10:31:18 <`jpi> hi, what is this L3 INSTR ? Jun 25 10:31:40 <`jpi> am335x spec Jun 25 10:33:21 what are we dissung Jun 25 10:36:35 BeagleBone Black open-source Linux computer unleashes innovation Jun 25 10:36:41 nice title for TI whitepaper Jun 25 10:36:49 beagle.. unleash.. I see what you did there. Jun 25 10:37:31 or it's just normal marketing mumbojumbo out of a random PR generator. Jun 25 10:42:05 I think you're giving them too much credit Jun 25 10:42:30 hi! Jun 25 10:43:17 Rotti: Jun 25 10:48:10 Quick question for the crowd (and I'm sure this has been asked before, sorry for causing any redundancy): Will the Beaglebone Black, while running Android, Successfully run Netflix? I am looking for a power/cost efficient replacement for a desktop media machine. Jun 25 10:48:35 Added bit, please do highlight me if you respond. Don't want to miss any replies :) Jun 25 10:48:37 usererror: I doubt it Jun 25 10:49:04 usererror: what resolution were you hoping to run at? Jun 25 10:49:16 I remember there being issues with arm versions and netflix.. 1280x720 Jun 25 10:49:31 don't quite need 1080p Jun 25 10:50:41 you might get away with it but I would be suprised; as decoding the DRM + decoding the video in software is a heavy task Jun 25 10:51:02 I suppose I might as well ask, are there frequent limitations with running video at higher resolutions (higher than 720p)? Jun 25 10:51:22 usererror: I think the highest supported resolution is 1280x1024 Jun 25 10:51:44 don't quote me on that though Jun 25 10:51:47 heh, power/cost efficient I would use a Nexus 4 Jun 25 10:52:34 I would love to go that route, but I'd just use my Galaxy Nexus when I retire it instead, except there are a lot of problems with the adapters, and the connection... Jun 25 10:53:18 Chromebook arm has a HDMI socket Jun 25 10:53:23 same cost Jun 25 10:53:59 If I were to go that route, I'd pick up a used motorola razr with its stand-alone hdmi and OTG support (with a new kernel), and then I have USB for a proper remote, since most require their own dongle. Jun 25 10:54:34 Yeah, still at that $300 price range Jun 25 10:55:43 Honestly a bit shocked I'm not getting hits on that in searches.. Jun 25 10:57:02 Seems like someone would have tried it by now.. half the price of one of the little media boxes Jun 25 10:57:41 usererror: it's not really marketed as a media machine... Jun 25 10:57:49 nor is the pi Jun 25 10:57:59 the pi is marketed exactly as a media machine Jun 25 10:58:01 but I get what you are saying Jun 25 10:58:16 it is nothing but a media chip, a gpu with an ARM hanging off it Jun 25 10:58:23 well, the pi is marketed as an entry level board for learning electronics Jun 25 10:58:38 that is the 'official' message anyway Jun 25 10:59:52 either way, it looks like a great piece.. if I can get netflix going on it, I'd grab 2.. one to play with and one to stick by the tv Jun 25 11:00:23 usererror: how about getting a cheap android HDMI stick Jun 25 11:00:34 MK808 or whatever Jun 25 11:01:28 mourning Jun 25 11:01:38 I'd want to fix one that is not locked down - full source available, but I'm checking that out right now.. its a good idea :) had forgot about those Jun 25 11:05:40 mk808 might work :) Jun 25 11:08:03 mk808? work? :/ Jun 25 11:08:28 I had mk802 IIIS I think, that thing did many things but working wasn't one of them Jun 25 11:09:06 crashing, failing at tasks and annoying me - yes, it was fairly good at that Jun 25 11:09:32 I haven't used one, but the MK80x are the ones everyone raves about Jun 25 11:09:57 usually until it fails for them ;) Jun 25 11:10:33 ahh Jun 25 11:10:36 that's why I bought a bbb instead, despite only a8 and single core - at least I could be reasonably confident that it will work most of the time Jun 25 11:10:45 which is why I don't go for anything locked down.. Jun 25 11:10:55 software fixes most issues.. Jun 25 11:11:01 hmm Jun 25 11:11:02 usererror: how about a wandboard or something like that; got a bit more oomph Jun 25 11:11:16 odroid if you're feeling risky Jun 25 11:11:30 usererror: unless the issue is poor soldering on USB sockets (one of the stick types had this problem) Jun 25 11:11:41 jackmitchell: why is odroid risky? Jun 25 11:11:43 price range is getting up there toward one of those shitty locked down (and massively over-priced) boxes Jun 25 11:12:14 kfoltman: I don't think the odroid gang do much with reliable or deterministic software Jun 25 11:12:30 (I'm currently undecided between wand vs x2 vs optimizing the code further) Jun 25 11:13:38 kfoltman: the original odroid is only just making mainline is a _very_ basic form http://linuxfactory.or.kr/archives/190 Jun 25 11:15:45 well, to be fair, bbb didn't make the mainline either, but I'll keep looking, if their custom kernels suck and are unstable, then odroid is out for me Jun 25 11:16:59 kfoltman: not yet, but at least the bb* has a good patch structure and is trying for mainline; I think you get what you're given with odroid without any real support channels Jun 25 11:19:09 usererror: no Jun 25 11:19:11 it wont Jun 25 11:19:23 av500 : thnx :) Jun 25 11:19:27 I take it you've tried it? Jun 25 11:21:50 no Jun 25 11:22:28 ah Jun 25 11:23:18 well, might still make a decent headless linux machine with a battery backup.. Jun 25 11:23:36 so I'll still consider it for that Jun 25 11:23:41 headless netflix is kinda pointless Jun 25 11:23:53 thought the MPAA might approve Jun 25 11:24:00 lol Jun 25 11:24:38 av500: I'd prefer headless MPAA Jun 25 11:24:38 easier than porting ubuntu touch over to an old android phone just to have the UI overhead for nothing :p Jun 25 11:25:40 <`jpi> av500: you know about L3 INSTR ? Jun 25 11:25:55 in what context? Jun 25 11:26:07 <`jpi> clock management Jun 25 11:26:11 <`jpi> am335x spec Jun 25 11:26:50 its a register Jun 25 11:28:00 <`jpi> yes but what is it for ? Jun 25 11:28:17 `jpi: what does the TRM say? Jun 25 11:28:24 <`jpi> jackmitchell: nothing Jun 25 11:28:52 <`jpi> omap specs are better Jun 25 11:30:17 `jpi: CM_PER_L3_INSTR_CLKCTRL ? Jun 25 11:30:33 <`jpi> yes Jun 25 11:30:48 and the page in the TRM doesn't tell you what you need? Jun 25 11:30:56 <`jpi> no Jun 25 11:31:05 This register manages the L3 INSTR clocksm what else do you need to know? Jun 25 11:31:22 <`jpi> what is L3 INSTR ? Jun 25 11:31:27 no idea Jun 25 11:31:37 <`jpi> jackmitchell: wtf Jun 25 11:33:03 L3 is an interconnect Jun 25 11:33:06 sure Jun 25 11:33:08 what do you want to do with it? Jun 25 11:33:15 but what is INSTR? Jun 25 11:33:16 connect inters with it Jun 25 11:34:37 INtentionally SecreT Register Jun 25 11:34:39 there Jun 25 11:35:03 set it to 54 Jun 25 11:37:10 `jpi: there are references to it in the Linux kernel, have you followed those? Jun 25 11:37:23 yes, they set the register to some value Jun 25 11:39:20 <`jpi> jackmitchell: no Jun 25 11:39:31 wtf is IEEE5000? Jun 25 11:39:46 <`jpi> just enable it could not be the answer Jun 25 11:40:45 you have not worked much with TI, have you? Jun 25 11:41:57 ah, its a type, its IEEE1500 Jun 25 11:42:07 typo Jun 25 11:42:43 if you ask me, I assume its some "instrumentation" feature for debugging Jun 25 12:14:39 av500: IEEE5000 sounds like KIT 2000 Jun 25 12:15:10 KotH: shouldn't that be KI 2000? Jun 25 12:15:20 hmm.. right Jun 25 12:15:26 Knigh Industries Two Thousand Jun 25 12:15:41 KotH: its funny, the TRM uses 1500 and 5000 and of course its all IEEE5000 in the kernel source Jun 25 12:15:46 * koen glues on some more chestheir and steps into his car Jun 25 12:16:03 koen: btw, can we run our code on the M3? Jun 25 12:16:31 av500: we should Jun 25 12:17:06 the pm-firmare.m3 kinda ruins the whole jedi-handwave "there is no M3" TI is doing Jun 25 12:17:08 <`jpi> koen: huh? Jun 25 12:17:21 the firwmare is available IIRC Jun 25 12:17:26 it is Jun 25 12:17:29 opensauce as well Jun 25 12:17:38 perhaps we should integrate it in our build? Jun 25 12:17:41 <`jpi> koen: wher is thy source ? Jun 25 12:18:08 koen: source where? Jun 25 12:18:10 panto: I integrated it a long time ago Jun 25 12:18:26 oh, sorry didn't know Jun 25 12:18:58 http://arago-project.org/git/projects/?p=am33x-cm3.git;a=summary Jun 25 12:18:59 koen: M3? Jun 25 12:19:20 KotH: not a gun Jun 25 12:19:21 https://github.com/Angstrom-distribution/meta-ti/blob/angstrom-staging-yocto1.3/recipes-bsp/ti/am33x-cm3_git.bb Jun 25 12:19:39 av500: what is it then? a BMW? Jun 25 12:19:48 cortex-m3 Jun 25 12:19:54 hmm? Jun 25 12:19:56 for "power management" according to TI Jun 25 12:19:59 on the bbb? Jun 25 12:20:02 yes Jun 25 12:20:06 dont you read the docs? Jun 25 12:20:07 so ka.. Jun 25 12:20:09 nope Jun 25 12:20:16 i read irc Jun 25 12:20:24 real knowledge comes from irc Jun 25 12:20:39 * koen shouts some more guesses Jun 25 12:20:45 <`jpi> how do you plan on using it ? Jun 25 12:21:07 to gain world domination! Jun 25 12:21:26 <`jpi> as i read it is mutually exclusive with the cortex-A8 core ? Jun 25 12:21:30 no Jun 25 12:21:38 why would it be? Jun 25 12:21:38 just no Jun 25 12:21:50 and how would one even implement that Jun 25 12:21:50 <`jpi> oh, ok Jun 25 12:22:03 av500: people who mentioned syslink support for that M3 quickly had a black pillow case over there head and now live in gitmo Jun 25 12:22:09 their* Jun 25 12:24:28 koen: friends of you? Jun 25 12:24:36 koen: do you need a rescue party? Jun 25 12:25:00 koen: I was about to mention it Jun 25 12:25:02 lol Jun 25 12:25:04 now I wont Jun 25 12:26:52 av500: syslink is a wbu/c6000 ism Jun 25 12:26:59 the am335x is an AMBU project Jun 25 12:27:19 so you're only allowed to mention excrement related terms when talking about syslink Jun 25 12:27:25 "dsp crap" Jun 25 12:27:41 * panto is looking at ducati virtio stuff right now Jun 25 12:27:49 holy sh*t is it over complicated Jun 25 12:27:53 you know, the usual TI political crap Jun 25 12:32:02 koen: doesnt AMBU has arm+dsp too? Jun 25 12:33:30 and is there a BUBU? Jun 25 12:36:15 nice, there are now e-waste bins around town Jun 25 12:36:30 you can throw a whole tower PC inside Jun 25 12:37:08 "Sub-Arctic PM Firmware" /me wonders what do they smoke there... Jun 25 12:37:18 av500: only the arm side is supported Jun 25 12:37:22 right Jun 25 12:37:30 av500: finally! .de is following .ch's lead there... after 20years or something :) Jun 25 12:37:33 ynezz: Sub-Arctic is the am335 code name Jun 25 12:37:44 but sounds funny Jun 25 12:38:10 KotH: well, there was e-waste before Jun 25 12:38:14 but you had to go somewhere Jun 25 12:38:31 sadly it does not fit CRT TVs Jun 25 12:38:34 don't you have relatives to unload old boxes? Jun 25 12:38:43 no Jun 25 12:38:51 tyropita wins Jun 25 12:39:35 I do wonder thought how they are going to recycle old tablet prototypes Jun 25 12:40:05 they'll send them to your competitors Jun 25 12:40:11 fine Jun 25 12:40:21 or to china Jun 25 12:40:29 well, they are all over china Jun 25 12:42:02 so, we'll see cheap clones soon? Jun 25 12:48:57 do I understand it correctly, that this am355x cm3 doen't have any flash, right? Jun 25 12:49:23 no Jun 25 12:50:37 can't parse that short answer Jun 25 12:51:07 -ENOPANTS Jun 25 12:51:13 linker script doesn't show any flash available either Jun 25 12:51:32 bradfa: much better, thanks Jun 25 12:51:36 :) Jun 25 12:51:54 no flash Jun 25 12:52:08 ok, who does linuxcnc in here? Jun 25 13:02:32 I'd like to do some milling work but I haven't found any hardware setups within my budget and I haven't found anyone local willing to go in on it. Jun 25 13:06:51 georgem: no fablab near you? Jun 25 13:10:26 KotH: yeah there is actually not quite as close as I'd like. Jun 25 13:16:27 requires month membership though... I should catch up on other tasks and sign up. Jun 25 13:16:57 yeah... Jun 25 13:17:02 they need to finance the place somehow Jun 25 13:17:09 i want to make one product basically for wireless hotspot . so beagleboard have mips arch. rather than arm ? Jun 25 13:17:30 perry_: there is no mips beagle Jun 25 13:17:57 Any other board you can suggest me on mips arch? Jun 25 13:18:13 KotH: was wishing they had a daily entrance fee instead of just monthly though. Realistically I'd be lucky to have 2 days a month to do it.. Jun 25 13:18:19 ask one of your indian friends. there are tons of wireless hotspots out there Jun 25 13:18:21 buy one cheap Jun 25 13:19:04 georgem: hmm...ours here in .ch has, afaik. but you are not allowed to use all machines then Jun 25 13:19:09 perry_: why does it have to be mips? Jun 25 13:19:37 because mips have more powerfull on networking side Jun 25 13:20:10 lol Jun 25 13:20:19 av500: ich bewundere wie du immer bei solchen leuten, die eindeutig sich nicht wirklich informieren wollen, nachfragst :) Jun 25 13:20:31 av500: am i wrong ? Jun 25 13:20:42 perry_: if that's your argument, get a PPC, these are the usual processor used for networking gear, like switches and routers Jun 25 13:20:52 what kind of "powerfull networking" does a wireless hotspot need? Jun 25 13:21:14 av500: gbit wireless with NAT and statefull inspection firewall! Jun 25 13:21:33 ah, the british variant Jun 25 13:21:37 juup Jun 25 13:22:42 av500: dont forget the usian variant with paket cloning and forwarding Jun 25 13:23:11 perry_: yes Jun 25 13:23:24 av500:: forgot it , you can suggest me any other board Jun 25 13:27:09 av500: hello Jun 25 13:27:13 hi Jun 25 13:27:48 hola Jun 25 13:28:22 beagleboard is perfect for my application. Jun 25 13:28:41 but you need MIPS Jun 25 13:28:50 million of instructions! Jun 25 13:29:38 yes right but if my aim is fullfil in arm then it's ok to goto arm side Jun 25 13:30:53 ah Jun 25 13:30:54 ok then Jun 25 13:38:00 Hi all - Noob alert Jun 25 13:38:08 I've just purchased the BBXM Jun 25 13:38:17 Using the standard Angstrom release Jun 25 13:38:34 don't seem to be able to get the bluetooth device to pair Jun 25 13:38:45 perry_: for a hotspot, take a look at something like carambola2 (bonus point, it's MIPS) Jun 25 13:39:21 Bluetooth dongle and keyboard are both working and can see each other, but i don't seem to have the bluez-tools to connect the devices together Jun 25 13:39:26 has anyone been able to do this? Jun 25 13:39:45 sure, using bt daily Jun 25 13:39:51 I don't have bluez-simple-agent Jun 25 13:39:54 or simple-agent Jun 25 13:40:03 so a little stuck on the last step Jun 25 13:40:11 can you help me do this without using the gui? Jun 25 13:41:31 no, sorry Jun 25 13:42:06 Thanks anyway Ynezz Jun 25 13:42:58 this is more general Linux question, not much related to beagleboard (apart from possible USB problems which you doesn't have probably as something is working already for you) Jun 25 13:43:36 more curious as to what tools are distributed with the angstrom release Jun 25 13:43:54 as all the tools in the tutorial don't seem to be available on the beagleboard xm angstrom release Jun 25 13:44:37 you know, tutorials especially those on the blogs and wikis became outdated Jun 25 13:45:05 usually they should give you a rough idea what needs to be done Jun 25 13:45:21 and the rest is up to you :) Jun 25 13:45:38 if I recall, rfkill was a big step in getting it working Jun 25 13:45:51 try to do the same working on some desktop Jun 25 13:46:37 take a look how does it work there, what's needed and duplicate the same(or similar setup) on the beagle Jun 25 13:46:45 there's no magic involved Jun 25 13:46:59 yeah the bluez4-tools package is required, it's not an option in opkg list Jun 25 13:47:17 thanks i'll do some more reading Jun 25 13:47:27 have been at it for a few hours so thought i'd check in with you guys Jun 25 13:47:41 just few hours? :p Jun 25 13:47:45 salut bradfa Jun 25 13:48:01 howdy KotH Jun 25 13:48:19 bradfa: hau di selber ;) Jun 25 13:48:52 took me a few days to get bluetooth somewhat working without, then our company decided t ditch it for the time being Jun 25 13:49:29 ha! Jun 25 13:49:29 KotH, anything exciting going on? Jun 25 13:49:33 painful! Jun 25 13:49:38 bradfa: not really... Jun 25 13:50:00 bradfa: doing some cheapish cortex-m3 controller board design for some medical comp Jun 25 13:50:35 cheapish and medical go in the same product? Jun 25 13:50:46 yeah.. Jun 25 13:50:55 we-dont-have-any-money kind of startup Jun 25 13:51:11 well.. it still costs quiet a bit :) Jun 25 13:51:24 but considering what it could cost, it's a cheap design :) Jun 25 13:51:31 KotH, there's other kinds of startups? Jun 25 13:51:53 :) Jun 25 13:51:58 yeah.. we had some who spend millions (litteraly) before they got to the first product release Jun 25 13:52:13 fuzzy mornings to all Jun 25 13:52:28 mranostay: BEER! Jun 25 13:52:46 bradfa: ofc, only one of those made it to product release ;) Jun 25 13:53:18 this SAKURA is a big POS Jun 25 13:53:25 mranostay, morning fuzzy :) Jun 25 13:53:25 the USB MSC is totally unstable Jun 25 13:53:36 there is a, gah, wen compiler Jun 25 13:53:38 web* Jun 25 13:53:42 no toolchain Jun 25 13:53:43 KotH, yeah, that sounds like most startups that try to do hardware Jun 25 13:53:44 no programmer Jun 25 13:53:57 bradfa: http://www.fuzzyduckbrewery.co.uk/ <--- beer for you Jun 25 13:54:00 * KotH takes a stepladder and pats av500 on his head Jun 25 13:54:16 mranostay, +1! Jun 25 13:54:57 KotH, don't ask how much we've spent on hardware development :) Jun 25 13:55:43 bradfa: you know, you could just ask us. we do professional hw design ;) Jun 25 13:56:06 lol, the ph0rum is "renesasrulz.com" Jun 25 13:56:08 OMG Jun 25 13:56:21 kanged? Jun 25 13:56:22 KotH: I thought the japanese were cool cats Jun 25 13:56:24 renesas sucks Jun 25 13:56:29 av500: you should know better than using any renesas uC/uP Jun 25 13:56:34 he Jun 25 13:56:42 we uses SH-1 for our mp3 design :) Jun 25 13:56:45 used* Jun 25 13:56:50 av500, I hear it's super Jun 25 13:57:19 KotH, we could, yes, but we could probably save a bunch of money on development by not going to china before we should... Jun 25 13:57:35 china is cheap Jun 25 13:57:42 av500, yes, and that's about it Jun 25 13:58:11 LLLOOOLLL: http://renesasrulz.com/app_kits_and_demo_boards/gadget_renesas_user_forum/f/128/t/4007.aspx Jun 25 13:58:14 bradfa: we even offer doing production in china :) Jun 25 13:58:24 how about a fucking toolchain instead??? Jun 25 13:58:34 av500, I enjoy your pain :) Jun 25 13:58:41 not pain Jun 25 13:58:45 I got it for free Jun 25 13:59:02 thought I might power it up before I dump it on "the pile"(tm) Jun 25 13:59:04 I never found free working toolchain for the renesas dev board I had. Jun 25 13:59:10 I've toolchain for sh-3 somewhere :p Jun 25 13:59:14 av500, current colors are pink! I like it! mranostay I think you might have designed that Jun 25 13:59:18 that hew crap Jun 25 13:59:18 ynezz: me too, gcc Jun 25 13:59:31 yeah it was hew Jun 25 13:59:33 worked fine back then on the SH-1 Jun 25 13:59:44 av500: what saukra? an arduino clone using an cortex-m3? Jun 25 13:59:50 sure, it works, but... Jun 25 14:00:01 KotH: no Jun 25 14:00:04 renesas Jun 25 14:00:07 sauerkraut Jun 25 14:00:08 hew is trial ware Jun 25 14:00:10 the good shit Jun 25 14:00:19 av500: complete own design?

Jun 25 14:00:38 yes Jun 25 14:00:56 * av500 sets up a donation begging banner Jun 25 14:01:01 looks like gay dating site Jun 25 14:01:06 haha Jun 25 14:01:11 "Hi, I am Kevin Spacey and I want your money" Jun 25 14:01:43 ynezz: it might in fact be more successful at that Jun 25 14:02:36 wow, they have "google translated" documenetation Jun 25 14:02:39 -e Jun 25 14:03:16 av500: own design Jun 25 14:03:29 av500: as i said: stay away from renesas Jun 25 14:09:09 hi LetoThe2nd Jun 25 14:12:06 panto: howdy Jun 25 14:13:30 ah, there is a toolchain Jun 25 14:13:40 something hew that smells a lot like gcc Jun 25 14:14:08 av500: smells like RMSpirit?

Jun 25 14:32:11 heh Jun 25 14:44:11 Hi everyone, is it possible to flash the kernel with out flashing the fs? leaving the original fs on the beaglebone? Jun 25 14:44:40 sure Jun 25 14:45:22 what you call "flashing" is a mere "copy" Jun 25 14:45:28 and files can be copied Jun 25 14:45:56 ok, so i can just overwrite the old kernal with the new one? Jun 25 14:46:01 yes Jun 25 14:46:09 you might also copy the new modules Jun 25 14:46:37 ok, i'll give it a shot. Thanks Jun 25 14:54:59 is there a way to change the threshold at which the low disk space warning shows up in angrstrom? Jun 25 14:55:22 I dont think it's fixed in hardware Jun 25 14:55:40 so, yes Jun 25 14:56:01 more refined question, does anyone know how? Jun 25 14:58:00 whats the FS anyways? ext? Jun 25 14:58:28 angstrom runs gnome, no? Jun 25 14:58:33 yes Jun 25 14:58:36 I guess its a gnome thing then Jun 25 14:58:50 some little gnome inside Jun 25 14:59:02 ah you mean that way. Jun 25 14:59:32 alright, ill dig from there. Thanks I'm not a very experienced linux user Jun 25 15:21:40 has anyone here had experience with eclipse kepler and gcc4.7? Jun 25 15:23:10 thurgood_: is kepler the new, new one Jun 25 15:23:18 being released this month? Jun 25 15:23:34 if so, no; if it's the one released last year then yes Jun 25 15:23:49 is their anyone here who is kinda expert at i2c? Jun 25 15:25:04 jackmitchell: when i write -i2cdump Jun 25 15:25:11 where does this get all this dump from? Jun 25 15:25:18 the i2c bus Jun 25 15:25:34 yes it's the new one... juno seems to have fallen apart since the adoption of gcc4.7 on ubuntu Jun 25 15:25:46 alright if i wanted to change the printf that comes from the dump can i do that? Jun 25 15:26:03 thurgood_: I work with GCC 4.7/4.8 and have no isssues Jun 25 15:26:18 Ahmed_: not really Jun 25 15:26:37 you could use regex to match the output; but I imagine there are easier ways Jun 25 15:26:47 it compiles fine, but shows errors everywhere, starting a couple of days ago Jun 25 15:26:54 Hello everyone, would someone tell me how to enable the auto login for Beaglebone running ubuntu 12.04? Jun 25 15:27:08 it's not gcc itself I don't think but CDT Jun 25 15:27:21 ah, what CDT version? Jun 25 15:27:59 I tried /etc/inittab and found: "S:2345:respawn:/sbin/getty 115200 ttyO2" Jun 25 15:28:01 it says 8 Jun 25 15:28:28 yeah, I use 8.1.2 over here and it's ok Jun 25 15:28:34 not on Ubuntu though Jun 25 15:28:59 Eclipse can be a funny beast at times Jun 25 15:29:38 s/at times/always/ Jun 25 15:29:45 it was going along fine until sometime over the weekend Jun 25 15:30:19 then it suddenly couldn't find headers in the include directories Jun 25 15:30:34 does it manage your build for you? Jun 25 15:30:43 jackmitchell: :D alright i have a question, i have at90usb 1287 from atmel and this thing have temp sensor Jun 25 15:30:44 yes, it builds fine Jun 25 15:30:48 i.e. automatically generate the makefiles? Jun 25 15:30:54 but i dont know how to get the data from this device Jun 25 15:31:17 Ahmed_: I don't know either I'm afraid Jun 25 15:31:27 but if it's going to say every other line is an error I might as well use a text editor Jun 25 15:31:48 thurgood_: do you reference your includes from the root directory? Jun 25 15:31:56 *root project directoy Jun 25 15:32:12 no, from filesystem root Jun 25 15:32:22 hmm, that's an odd way of doing it Jun 25 15:32:32 are you cross compiling or build native apps Jun 25 15:33:31 cross compiling for omap3530 and testing some application code on the desktop Jun 25 15:33:50 it sounds odd that you reference your makefiles with an absolute path Jun 25 15:34:06 sorry reference your includes with an absolute path Jun 25 15:34:51 possibly play around with the Project->Preferences->C/C++ General->Paths and Symbols windows Jun 25 15:35:46 but I would definitely say it is a build system problem, rather than a GCC problem Jun 25 15:36:14 it just seems weird to me that this happened suddenly, I don't think I changed any settings I was simply merging source code from an old project Jun 25 15:36:34 obviously /something/ changed Jun 25 15:37:25 thurgood_: sometimes, because Eclipse automatically regenerates Makefiles on the fly, it only takes a little tweak for the system to blow up Jun 25 15:38:12 When following the instructions at http://elinux.org/BeagleBoardDebian on making a bootable SD-card with debian, where am I supposed to execute the "/.setup_sdcard.sh" command? On the SD-card, on the beaglebone? It's for a BBB. Jun 25 15:43:26 l0di: I would guess on your host PC Jun 25 15:43:36 that needs to be running Linux Jun 25 15:44:34 jackmitchell: Ok, so I have the files locally on a linux system with the card plugged in. Or are the files supposed to be on the card? Thanks Jun 25 15:45:14 ok, do you know what device your SD Card is? Jun 25 15:45:25 /dev/sd.... Jun 25 15:46:33 l0di: if you do: sudo fdisk -l and try and find your SD card in the list Jun 25 15:49:29 jackmitchell: I have an ubuntu comp that is not with me now, I'm on a mac right now. Maybe that could work? Jun 25 15:50:24 hmm, probably not Jun 25 15:50:47 I would wait till your on a Linux machine Jun 25 15:51:05 jackmitchell: ah well, I'll try it on that then. Thank you so much for the help. Jun 25 15:51:18 l0di: np Jun 25 15:56:25 ah... fedex just dropped of 3 bb-xm's :) Jun 25 15:57:22 i wish fedex would give me free stuff :P Jun 25 16:00:18 lol... now the work begins... Jun 25 16:00:28 mranostay -> www.liquormart.com Jun 25 16:02:03 bradfa: yes? Jun 25 16:06:25 bradfa: don't think i'm ever had alcohol shipped to me.. seems to big of a bother Jun 25 16:12:21 I have had a barrel delivered once. Jun 25 16:12:30 It was 98% sulphuric acid though. Jun 25 16:13:40 damn ... reminds me I need some acid to clean an oak barrel for my rum Jun 25 16:20:04 * mranostay rides the wave Jun 25 16:23:00 mranostay: You hace a rather large girlfriend ;) Jun 25 16:23:07 s hace/have Jun 25 16:23:55 * djlewis is still asleep. add a question mark. Jun 25 16:26:19 djlewis: how dare you Jun 25 16:26:43 gm :) Jun 25 16:27:29 did she returned -1 when sizeof'ed ? Jun 25 16:29:12 sir, how dare you Jun 25 16:29:58 sorry for the joke, and very sorry for the grammar mistake (priorities man) Jun 25 16:43:21 ok so stupid beginner question, if I build a custom ångström image using the online build bot, will it always have the usb gadgets for serial and ethernet in the kernel? Jun 25 16:43:35 so I can get access to them in the same way as the "stock" demo ångström Jun 25 16:55:34 errr ok another noob question.. is this narcissus even capable of rolling a BBB distro for me.. :P Jun 25 17:16:23 ok I'm going with arch for now.. I know arch :) Jun 25 18:36:52 * bradfa loves git commits that comment out code and do nothing else... Jun 25 18:43:38 This is a stupid question but how do I use a .tgz file on the BBB? There doesn't seem to be any application installed to handle it Jun 25 18:45:46 aathma: tgz is short for .tar.gz Jun 25 18:45:56 aathma: and you should have tar and gzip installed Jun 25 18:47:29 I get the dialog stating that there is no application installed for tar archives and such Jun 25 18:47:49 use the commandline Jun 25 18:47:50 forget the gui Jun 25 18:47:56 tar -xzvf file.tgz Jun 25 18:50:36 we arent in kansas anymore Jun 25 18:51:33 Lol. I've kinda been thrown into the linux environment with no experience Jun 25 18:51:56 quick, kill the witch with the silver slippers and grab them Jun 25 18:52:07 I was great with Dos when I was little and have developed for Windows but this is so different Jun 25 18:53:15 welcome to oz Jun 25 18:53:29 to your right, you see the command line, to your left is /dev/null Jun 25 18:53:37 we hope you enjoy your stay Jun 25 18:54:10 watch out for /dev/random Jun 25 18:54:23 I love it! It's just a bit of a learning curve right now. Do we know if anyone has had luck with using Processing on Angstrom? Jun 25 18:54:26 dmesg is your friend Jun 25 18:54:52 aathma, yes, a bit of googling should show up some results Jun 25 19:05:17 howdy, I'm trying to do a simple inline neon adder, but I don't think my load/stores are working properly. Can anybody point me in the right direction with this: https://gist.github.com/n-west/5861300 ? Jun 25 19:14:40 n|west: why not use intrinsics? Jun 25 19:15:40 kfoltman: I've got an equivalent intrinsic function, and just playing around with what is faster. Also using this as a building block to do more complex things inline Jun 25 19:15:53 n|west: have you looked at the generated .S? Jun 25 19:16:21 mru, you awake Jun 25 19:16:31 yea. It looks ok, except that the registers gcc chose to use don't have any init, so there's garbage in them instead of my addresses Jun 25 19:17:00 n|west: BTW why num points is divided by four instead of two? Jun 25 19:17:22 quadwords take in 4 floats, no? Jun 25 19:18:44 I can gist the generated .S file too, if it will help and you don't mind looking at it :-p Jun 25 19:18:59 or at least the relevant portion Jun 25 19:19:14 n|west: if you can pastebin it? although I never used the inline asm yet Jun 25 19:19:23 still, learning something new sounds like a good thing Jun 25 19:19:37 work bans pastebin :-/ is gist ok? Jun 25 19:19:42 possibly? Jun 25 19:19:48 at least the intrinsics operate on the float32x2 type, not float32x4 AFAIK Jun 25 19:20:06 n|west: Try using lug.mtu.edu/pastebin. Jun 25 19:20:09 hmm, adding a q to the intrinsics makes them operate on float32x4 Jun 25 19:20:49 so vaddq_f32 operates on two float32x4_t's Jun 25 19:24:24 So I just realized I've been using the Angstrom "unstable" branch since 2007 or so, revision C3. Jun 25 19:24:27 Very very out of date. Jun 25 19:24:41 Can someone suggest my fastest course of upgrading without breaking things? Jun 25 19:25:06 updated the gist with the whole function (there's some cleanup code) and the output .S: https://gist.github.com/n-west/5861300 Jun 25 19:25:42 Is it possible to just change the opkg lists to something more up to date and just opkg upgrade, or would I be better off starting over from scratch with a newer demo? Jun 25 19:30:23 n|west: so, r8 is quarterPoints, ip is number... mov r6, r1 is r1->r6, right? (and r1 is the second argument per ABI?) Jun 25 19:32:34 I would have thought r7 is quarterPoints Jun 25 19:33:20 ip is a regualr reg with a funny name Jun 25 19:33:35 r12 Jun 25 19:33:43 WizardStan: get another sd card. upgrade will most likely make you a unhappy camper. Jun 25 19:33:43 thats what I thought Jun 25 19:33:44 but otherwise that looks right. There's a verbose asm command, righht? any idea what it is? or I'm off to the google Jun 25 19:33:46 n|west: but it compares r8 with ip in line 80 Jun 25 19:33:51 mru are you hunting reindeer? Jun 25 19:33:53 please don't call it ip Jun 25 19:34:03 gcc is calling it that Jun 25 19:34:10 mru: makes it too easy to confuse with intel instruction pointer? Jun 25 19:34:15 no excuse Jun 25 19:34:24 :) Jun 25 19:34:27 yeah Jun 25 19:34:30 kfoltman: one reason Jun 25 19:34:36 I knew there where some funny names Jun 25 19:34:43 I can say I was confused until I looked it up Jun 25 19:35:28 there's fp and sl too Jun 25 19:35:47 fp and sp? Jun 25 19:35:50 don't use those names either Jun 25 19:35:58 sp is ok Jun 25 19:36:07 what's sl? Jun 25 19:36:22 subroutine link? Jun 25 19:36:22 http://msdn.microsoft.com/en-us/library/ms253914(v=vs.80).aspx Jun 25 19:36:31 r10 iirc Jun 25 19:36:48 it's in the arm abi spec Jun 25 19:37:09 impressive :-o Jun 25 19:37:36 mru sleeps with the arm arm Jun 25 19:37:37 n|west: I don't know what I'm doing, but to me, at least the loop and the initialisation of the addresses looks perfectly fine Jun 25 19:37:55 alrighty, I just spit out the verbose assembly, checking if it's more useful Jun 25 19:38:10 n|west: can you stepi it in gdb? Jun 25 19:38:11 neon intrinsics suck btw Jun 25 19:38:31 Hi guys, I got myself a BBB last week, and been struggling with getting a accelerometer to work. I have no idea on what ports to use Jun 25 19:38:39 djlewis: that was my fear. I spent years getting things "just so" and don't really want to start over, but gotta do what you gotta do. :P Jun 25 19:38:42 Thanks. Jun 25 19:38:42 *pins Jun 25 19:38:42 mru, meh, it's an point before you go full assembly Jun 25 19:38:43 don't even think about using them with gcc <4.8 Jun 25 19:38:56 mru: that's why I'm trying to figure out how to do it inline Jun 25 19:39:00 mru: still, the difference between intrinsics and plain old FPU code is enormous Jun 25 19:39:25 also, gcc syntax for assembly is, um, challenging Jun 25 19:39:26 panto: plain asm is much easier Jun 25 19:39:33 kfoltman: I haven't seen a huge different when both are compiled with -O3 Jun 25 19:40:01 don't use inline asm EVER Jun 25 19:40:03 * Crofton|work threatens to make a milkshake from mru's brain and pass it around .... Jun 25 19:40:03 mru, depends Jun 25 19:40:16 mru, oh, I do it all the time Jun 25 19:40:16 mru: oh really? Jun 25 19:40:45 n|west: rewriting my cubic resampler code using intrinsics (I don't remember if it was gcc 4.7 or 4.8) made it something like 4x faster, or more Jun 25 19:40:52 however Jun 25 19:40:55 mru: so you would suggest a straight asm? Jun 25 19:41:00 c has never really translated to horribly efficient SIMD code generation on any architectures... Jun 25 19:41:03 kfoltman: straight float code on a8 sucks Jun 25 19:41:08 it is VERY easy to make it suck Jun 25 19:41:22 the compiler is moronic and you need to avoid accidental use of regular FP Jun 25 19:41:41 so, it's pretty much "change something and look at disassembly and vomit" Jun 25 19:41:55 I'm assuming inline suffers from the constraint madness? Jun 25 19:42:06 you should get 8-10x speedup with neon on a8 Jun 25 19:42:08 Crofton: that's the problem, for me at least Jun 25 19:42:20 mru: is the same true on a9 though? Jun 25 19:43:16 mru: good to know (unfortunately the inner loops for interpolation and IIR filtering are not the only CPU-intensive parts of the sampler code, so there's only so much I can gain by hand-optimizing those) Jun 25 19:44:24 n|west: my impression was that hand optimized neon gives much better performance on a8, because it's stupid and in-order execution AFAIK Jun 25 19:45:32 the headache doing straight .s is you also need to understand the abi stuff Jun 25 19:45:32 with out-of-order you get better "default" behaviour from the CPU, and it's also harder to predict CPU behaviour for optimization purposes Jun 25 19:45:51 Somebody who got experience with hooking up a Memsic 2125 accelerometer with a Beaglebone Black? As far as I know it has a PWM output, but how do I read this signal? Jun 25 19:47:03 Crofton: but, is abi really that difficult? Jun 25 19:47:39 I can only handle learning one thing at a time Jun 25 19:48:03 all tradeoffs Jun 25 19:50:29 so I added a -fverbose-asm file to that gist, makes it clearer what registers are set to which variables Jun 25 19:51:17 did you update what is there Jun 25 19:52:05 there should be 3 files there right now Jun 25 19:52:07 yeah Jun 25 19:52:08 one .c and two .s Jun 25 19:52:26 the verbose .s is the last one Jun 25 19:52:45 you need to find the flag for stop-using-stupid-register names Jun 25 19:53:58 for stuff like ip? Jun 25 19:54:09 yeah Jun 25 19:58:34 ok so putting arch on the BBB was a breeze.. but I was thinking that the user leds would be ark under the arch, yet they still blink away. Jun 25 19:58:52 where is the user led activity blinking done? Jun 25 19:59:25 n|west: but, what's the problem, does it not work? Jun 25 20:00:13 kfoltman: right, it runs but gives a different output from straight C given same output. (it returns all 0's) Jun 25 20:05:43 kfoltman: the loads come from r1 and r2, but I don't see where addresses aPtr and bPtr are loaded in to r1 and r2 (but maybe I'm just missing it...) Jun 25 20:05:55 which is what was making me think maybe I just didn't have the gcc syntax quite right Jun 25 20:06:00 bed time Jun 25 20:06:18 n|west: that's part of the ABI I think Jun 25 20:06:27 n|west: the first 3 arguments are passed as r0, r1 and r2 Jun 25 20:06:35 ahh Jun 25 20:06:46 that makes a lot more sense Jun 25 20:07:16 however, I'm not sure if gcc realizes that r5, r6 and r7 are being changed by the code Jun 25 20:08:38 asm ? Jun 25 20:08:40 err r4, r5, r6 Jun 25 20:08:49 ok, but it never uses r4/r5/r6 later so it's ok I suppose Jun 25 20:08:51 yea, r7 is definitely working Jun 25 20:09:02 hello everyone Jun 25 20:09:06 at least not before setting them to different values Jun 25 20:09:15 hallo for all yo ugermans Jun 25 20:09:18 m_billybob: yes, we're trying to figure out why some NEON code isn't working Jun 25 20:09:23 the intrinsics version I have moves r0-2 -> r4-6, interestingly Jun 25 20:09:42 ah Jun 25 20:09:46 n|west: it's so that the original values aren't clobbered by the loop Jun 25 20:09:53 because they're used later on Jun 25 20:10:14 add r0, r0, r5 where r5 = sl << 2 ? Jun 25 20:10:30 or r10 << 2 for mru's sake Jun 25 20:10:42 :) Jun 25 20:11:29 n|west: can you try using gdb to verify that the output array is indeed wrong and it's not something else? Jun 25 20:11:48 I can try :-o Jun 25 20:12:09 I mean, the alternative explanation would be that the calculation code is correct, but the inspection code is led astray by some side effects of the calculation code Jun 25 20:12:49 also, can you try making the function non-inline, just for clarity? Jun 25 20:13:05 otherwise it gets mixed up with the calling function and the result is bit hard to read Jun 25 20:25:08 mru, are you near osterlund? Jun 25 20:28:57 another newb question: is there a good guide for using gdb/server for cross debugging? I can run and do bt's, but I can't ever seem to load source files to set break points Jun 25 20:29:31 we need to mess with the yocto adt one day :( Jun 25 20:29:52 I am sad because eclipse is invovled :) Jun 25 20:29:56 args are in r0-r3 Jun 25 20:29:58 noooo! Jun 25 20:30:15 Crofton|work: wash your mouth out! Jun 25 20:30:25 heh Jun 25 20:30:28 r0-r3, r12, r14 are call-clobbered Jun 25 20:30:49 I talked to some guys that said eclipse is great once you get it setup and have other people use it :) Jun 25 20:31:06 bbiab Jun 25 20:31:14 I ahve to pick up our weekly vegatables Jun 25 20:31:21 vegetables Jun 25 20:31:36 heh Jun 25 20:31:47 i thought that was some new fangled vegan thing Jun 25 20:32:22 I suspect Crofton|work may actually be a hippie. Too much cycling and vegetables Jun 25 20:33:03 there's no hippies in Virginia ;) Jun 25 20:33:31 mru: how do I add r12 and r14 to the clobbered register list if they are chosen by gcc? Jun 25 20:33:31 n|west: dunno about tuts.. but make sure you compile symbols into the binary Jun 25 20:34:14 at least while debugging actively Jun 25 20:35:06 Crofton|work: I was in the eclipse is fine camp until it blew upon me yesterday :/ Jun 25 20:35:46 blew up on Jun 25 20:35:51 thurgood: is there more involved than -DCMAKE_BUILD_TYPE=Debug ? Jun 25 20:36:00 n|west: mucking with inline? Jun 25 20:36:07 mru: yea Jun 25 20:36:15 don't Jun 25 20:36:49 not sure if it's the project or eclipse itself that's at fault now, spent most of the day rebuilding the project from sources with the same result Jun 25 20:37:22 mru: is it not a good middle ground between intrinsics and straight .S? Jun 25 20:37:25 if you don't know why inline is almost always a bad idea, you won't be able to make it work Jun 25 20:37:31 no Jun 25 20:40:44 I can't find the ambient operating temperature range for the BBB in the SRM or elsewhere..? Jun 25 20:40:57 that seems like a catch 22 Jun 25 20:44:17 volatile. Jun 25 20:44:27 * KotH grabs popcorn Jun 25 20:49:39 yea so I'm blind, stab me with an icepick and tell me the min/max operating temp for the BBB :) Jun 25 20:52:02 <_av500_> between freezing and searing Jun 25 20:58:32 av500, thanks! Jun 25 20:58:58 ok let's put it this way, will a constant +35° ambient be a problem? Jun 25 21:00:09 and no I'm not putting it up my ass.... Jun 25 21:00:33 once I picked up the vegetables on my bike Jun 25 21:01:42 ok yes I was blind dammit.. gerald says 0-50°C in the google group.. Jun 25 21:02:58 <_av500_> 35 is fine Jun 25 21:03:43 0C is the min? Jun 25 21:03:59 damn, there fo my plans for the wall Jun 25 21:04:03 anyone got an eagle lbr for the CAT24C256 used on beagle capes? Jun 25 21:04:26 yea the cpu is good to -40 but apparently some other components only rated to 0°C Jun 25 21:05:19 I intend to leave mine out for -30°C temperatures.. but it's going to be in a small box so I assume it will be able to heat itself ;) Jun 25 21:05:32 prpplague: https://github.com/CDA0/eagle Jun 25 21:05:40 vaizki_: I guess I have to wait for the BeaverBoard Jun 25 21:05:59 or even better, the WolverineBoard Jun 25 21:06:01 BearBoard Polar Edition Jun 25 21:06:11 In general - you should read the datasheet really carefully. Jun 25 21:06:28 heh Jun 25 21:06:29 wmat: thanks Jun 25 21:06:31 It can be that large temperature swings will require a clock recalibration, or the system will crash. Jun 25 21:06:58 crash how? Jun 25 21:06:59 vaizki_: high altitude? Jun 25 21:07:03 speed, no Jun 25 21:07:07 just Finland Jun 25 21:07:15 canada Jun 25 21:07:17 vaizki_: The clock stops oscillating, and it dies. Jun 25 21:07:33 I'm fine with it rebooting Jun 25 21:07:40 Doesn't reboot Jun 25 21:07:45 At least on some platforms Jun 25 21:07:49 until it thaws Jun 25 21:07:53 watchdog doesn't reboot it? Jun 25 21:07:53 IIRC some gumstix did this. Jun 25 21:07:56 No. Jun 25 21:07:56 reboot on thaw! Jun 25 21:08:09 <_av500_> below 0 the clock freezes Jun 25 21:08:23 <_av500_> loading web pages gets awfully slow Jun 25 21:08:26 Technically - the VCO stops working. Jun 25 21:08:32 <_av500_> at -10 the cursor stops blinking Jun 25 21:08:42 Or more accurately - drifts out of operating range. Jun 25 21:09:13 * SpeedEvil was having problems financially a bit ago. Jun 25 21:09:28 many gadgets do not charge at below 7C. Jun 25 21:09:34 * wmat may in a bit Jun 25 21:09:59 hmmh Jun 25 21:10:08 I may have to put in an an external supervisor then Jun 25 21:11:32 SpeedEvil: 7C! Jun 25 21:12:11 Electric blanket ++ Jun 25 21:12:21 but then again, who charges their devices in the cold? Jun 25 21:12:25 I'm saving up so I can properly insulate the house. Jun 25 21:12:26 I have some intersil supervisors but I don't think they go to -40 either Jun 25 21:12:39 SpeedEvil: I just insulated my garage Jun 25 21:13:06 <_av500_> wmat: gotta keep the car warm Jun 25 21:13:08 but I spend a lot of time there Jun 25 21:13:23 _av500_: nah, no cars in the garage Jun 25 21:13:26 * _av500_ just insulted the garage Jun 25 21:14:12 warm garages actually rust cars faster in northern climes where salt is used on the roads Jun 25 21:14:25 I just need a place to solder and weld Jun 25 21:14:46 <_av500_> and that does not heat it up already? Jun 25 21:15:07 yea I only have a carport here Jun 25 21:15:43 warm garage is a nice idea for cars but only if you keep a hobby car the entire winter Jun 25 21:16:43 _av500_: it does, but when friends are over they keep asking why I have to weld all the time Jun 25 21:17:25 <_av500_> they ask only once, I presume Jun 25 21:18:01 For most welding, you need copious ventilation. Jun 25 21:18:07 So it doesn't really help. Jun 25 21:18:18 no, but that's only because they're not allowed to drink beer in their garages apparently Jun 25 21:18:27 <_av500_> I solder fumes but I dont inhale Jun 25 21:18:48 Stick welding is especially nasty Jun 25 21:19:05 speed, umm you can have a fume extractor which filters..? Jun 25 21:19:23 vaizki_: True. Jun 25 21:19:32 <_av500_> or a wet rag in your face Jun 25 21:38:12 wmat: can't drink beer in a garage? what is this soviet russia? Jun 25 21:38:46 It's a really bad idea in general. Jun 25 21:39:10 Gasoline engines spew out all sorts of crap that you do not want on your hands when dealing with food Jun 25 21:39:17 Maybe not lead anymore. Jun 25 21:41:33 food != beer Jun 25 21:42:05 You're trying to say that beer isn't food? Jun 25 21:50:34 <_av500_> what, I can't have beers while I weld the fule tank? what has become of thois place? Jun 25 21:50:39 <_av500_> fuel* Jun 25 21:51:00 <_av500_> also, I dont take the beer into my hands Jun 25 21:58:06 ok this is interesting.. my HVAC raspi has died Jun 25 21:58:16 i drink beer while welding. fuck ti Jun 25 22:01:41 <_av500_> vaizki_: too hot or too cold? Jun 25 22:02:01 oh it's not controlling anything. just monitoring. Jun 25 22:02:05 it's a raspi ffs Jun 25 22:02:14 I don't want to die in a fire Jun 25 22:03:10 that extra BBB I ordered is finding use faster than I expected... Jun 25 22:06:36 in the schem.... of bbb it say i2c-1 and i2c-2 Jun 25 22:06:48 while when i do i2cdetect -l i get i2c-0 i2c-1 Jun 25 22:07:00 and i2c-0 doesnt work only i2c-1 works Jun 25 22:07:02 yea linux numbers them from 0 Jun 25 22:07:03 any idea? Jun 25 22:08:43 linux is not written in fortran Jun 25 22:08:46 the i2c-0 goes to the board info eeprom and the PMIC Jun 25 22:09:06 define "doesn't work" Jun 25 22:09:30 so technically beagleboard black just have i2c-1 Jun 25 22:09:39 i mean just one i2c working Jun 25 22:10:13 vaizki_: is that right? Jun 25 22:13:08 no no you can get both of them from P9 pins 17-20 Jun 25 22:13:20 at least based on the SRM Jun 25 22:15:44 mranostay: just fyi i have an updated schematic for the release version of the Bacon Cape up - http://www.elinux.org/Bacon_Cape#Design_Files Jun 25 22:15:56 mranostay: feel free to review and send feedback Jun 25 22:17:38 anyone playing webM videos in chromium browser on beaglebone black? Jun 25 22:17:42 im getting really choppy video Jun 25 22:20:52 mranostay: it's all about suburban marital bliss ;) Jun 25 22:21:08 Can someone validate that I should remove the MLO from the internal eMMC Angstrom (which I upped to 6/20 rel) before trying to boot Sitara on an SD card, which I made from the TI create-sdcard.sh? Jun 25 22:21:21 <_av500_> prpplague: burning 4 GPIOs on that 7-seg Jun 25 22:21:26 <_av500_> what a waste Jun 25 22:22:40 Oh, on a BBB, that is Jun 25 22:22:49 why would you remove it? Jun 25 22:22:49 _av500_: recommendations? Jun 25 22:23:54 vaizki_: because it will boot to Angstrom otherwise. And, I can't get to the damn uboot prompt, because my USB serial drops when the the BBB power cycles. PITA Jun 25 22:24:46 <_av500_> prpplague: joking Jun 25 22:25:01 I'm guessing my mileage has definitely varied Jun 25 22:25:21 _av500_: ahh ok Jun 25 22:27:30 http://26-26-54.hardwarebug.org/91 Jun 25 22:29:22 wmat: isn't all of canada the burbs? :P Jun 25 22:31:04 mranostay: just withing 100KM of the border Jun 25 22:31:16 mranostay: real canada is north of that Jun 25 22:32:08 so the parts we wouldn't roll over with tanks in a half hour :P Jun 25 22:32:12 <_av500_> the permafrost region? Jun 25 22:32:25 mranostay: yes Jun 25 22:32:37 that is a good plot for a novel... US invades Canada Jun 25 22:32:44 <_av500_> boring Jun 25 22:33:02 ok germany Jun 25 22:33:09 mranostay: i think that's a john candy movie Jun 25 22:33:13 <_av500_> it has already happened Jun 25 22:33:39 <_av500_> govmt here does not take a dump before asking the US Jun 25 22:33:46 * wmat will head north when the revoltion comes Jun 25 22:34:34 _av500_: cool :) Jun 25 22:35:20 * mranostay wonders what canadian revolution would look like Jun 25 22:35:32 witty comments and some fisty cuffs? Jun 25 22:35:59 the latter would suffice Jun 25 22:36:38 * wmat runs to coach soccer Jun 25 23:14:00 Hi guys Jun 25 23:16:46 hi Jun 25 23:37:15 Anyone using USB->Serial on Ubuntu for BBB? Does your connection drop when board cycles? Jun 25 23:38:44 heh define drop Jun 25 23:40:51 mranostay: well, when the board comes up, udev creates a /dev/ttyACM0 - That's how I connect. That device file goes away when the board is off, or power cycles Jun 25 23:53:51 mrjazzcat: black not white right? Jun 26 00:05:12 mranostay: yes. Black. Jun 26 00:05:48 mranostay: I put the TI SDK on Ubuntu 12.04 and updated the BBB to the 6/20 Angstrom. That's all good. Jun 26 00:06:48 mranostay: I also hacked the TI SDK scripts to allow an install on 13.04, so I'm using that now. Both systems had no /dev/ttyUSB, but rather that ttyACM0 Jun 26 00:07:10 mrjazzcat: using a FTDI chip? Jun 26 00:07:33 mranostay: I doubt it. I just have the USB cable that came with the BBB Jun 26 00:07:52 I just ordered an FTDI cable, so I could see if that one will do better Jun 26 00:07:58 oh serial gadget is enabled? Jun 26 00:08:10 yeah that is going to go up and down in a power cycle Jun 26 00:08:24 mranostay: It must be on by default. Is there a better way? Jun 26 00:08:42 * mrjazzcat misses the old-school cu /dev/ttyS0 :) Jun 26 00:09:04 mranostay: how do you connect to serial console? Jun 26 00:09:11 get a FTDI cable for the little header Jun 26 00:09:27 mranostay: awesome. Thanks! I'll be happier in a few days then Jun 26 00:13:32 if you really miss /dev/ttyS0... Jun 26 00:13:44 build a 16550 cape and wire it up to the GPMC Jun 26 00:14:59 be sure to do it in DIP form to offend Russ Jun 26 00:45:06 emeb_mac: did you bring any FPGAs for the class? Jun 26 00:45:28 class? no one told me there was a class. Jun 26 00:45:51 this is starting to seem like one of those dreams I have about not being prepared for a test... Jun 26 00:47:36 emeb_mac: i'll give you a F+ Jun 26 00:47:48 you big meanie Jun 26 00:48:41 that is Tartarus Jun 26 00:59:14 * mranostay steals a Molson from wmat's fridge Jun 26 01:01:14 * russell-- just flashed the angstrom 6/20 image last night, it's acting weird, stalling on Waiting for root device /dev/mmcblk0p2... Jun 26 01:03:37 do you have an sd card in there as well? Jun 26 01:10:50 thurgood: no Jun 26 01:11:07 after 60 seconds, it finishes booting Jun 26 01:11:52 but, seems like a regression Jun 26 01:45:40 lol, opkg is so friggin borken. Jun 26 01:50:39 pru_evtout_2: how so? Jun 26 01:53:01 I have a Beaglebone A6 and I can't get it to boot. I tried a fresh Angstrom image all 4 User LEDs light up for a few seconds and then User LED 0 blinks. When I screen the terminal nothing shows up although my Desktop PC is detecting it. Is my Beaglebone busted? Jun 26 01:57:59 russell--: i'm living in outdated land, so maybe it's been fixed. :) Jun 26 02:00:12 hello Jun 26 02:00:24 but i get a feeling that automated testing in opkg land is...not. :-| Jun 26 02:01:05 Guest23532: wuzup? Jun 26 02:01:49 * pru_evtout_2 ignores the "No packages removed" error, knowing that the packages are very very gone. Jun 26 02:02:51 geez does the LF want to make CFP as painful as possible? Jun 26 02:04:45 so, i'm using my beaglebone to connect to a cape, where the cape is connected to a socket that needs different gpio depending on what's in the socket. Jun 26 02:05:10 and all the possible configurations aren't known. Jun 26 02:05:15 ...how do i make device tree stuff work for me? Jun 26 02:05:56 could i make an overlay, on the fly, and load it? Jun 26 02:06:38 err, sorry, not needs different gpio, needs different pin mux settings. Jun 26 02:06:57 like pull up/down/highz Jun 26 02:08:37 did that 3.8 omap_mux patch ever make it into mainline? Jun 26 02:09:56 * pru_evtout_2 assumes that he's the only one in the world with this use case Jun 26 02:11:04 http://thread.gmane.org/gmane.linux.kernel/1469197 is that patch i'm thinking of **** ENDING LOGGING AT Wed Jun 26 02:59:58 2013
