  • [01:08:19] <mru> depends on who pays for the beer

  • [01:08:58] <SilicaGel2> wait, wait, now I think you're screwing with me. If somebody else buys the beer, I have no argument that the beer TASTES better .... but it doesn't get you drunk faster!!!
  • [01:10:03] <mru> well, the goal is to get koen drunk without paying too much, right?
  • [01:10:08] <aholler> netherlands, use a cake ;)
  • [01:10:18] <mru> so you get jkridner to buy the beer (or shots)
  • [01:11:35] <SilicaGel2> right, that's the goal. At least based on the premise that he won't let you put something into his pants unless you get him drunk first.
  • [01:11:36] <SilicaGel2> Will he?
  • [01:12:16] <mru> that might depend on your gender
  • [01:12:28] <SilicaGel2> ok, so I need a female agent.
  • [01:12:34] <SilicaGel2> This is getting very complicated.
  • [01:12:45] <aholler> adding some hw to the green cake might have good results too ;)
  • [01:12:48] <mru> then again, he has a gf so even that will require him being drunk
  • [01:13:02] <SilicaGel2> unless I get her drunk instead
  • [01:13:09] <SilicaGel2> that might be cheaper
  • [01:13:33] <mru> I don't know, haven't met her
  • [01:14:08] <nextime> hello all, is anyone using succesfully ffmpeg to decode (low resolution/bitrate/frame rate ) video on beagleboard?
  • [01:14:47] <aholler> a nice layout to keep a makerbot busy might help too.
  • [01:14:57] <mranostay> mru: are we talking about taking advantage of koen ? :)

  • [01:17:50] <SilicaGel2> no
  • [01:18:12] <SilicaGel2> I think the "get him drunk" plan is dfinitely "taking advantage," not "bribing"
  • [01:18:29] <SilicaGel2> Bribing is however another route. That may be cheaper than getting him drunk.
  • [01:19:14] <SilicaGel2> .oO( unless "green cake" means bribery? I didn't understand that bit )

  • [03:32:46] <prpplague> Russ: feel free to post elinux.org with hacks and info
  • [03:33:58] <prpplague> Russ: it was kind of a gee-whiz thing i did just educational purposes
  • [03:34:05] <prpplague> Russ: we have some schools using it
  • [03:34:23] <mdp> prpplague: Tartarus is already nagging me about whether it's working yet :) I can see I have some work to do for the am35x and 37x evms yet.
  • [03:34:34] <prpplague> mdp: hehe
  • [03:34:48] <mdp> prpplague: ok..forward me anything interesting on it
  • [03:34:49] <Russ> prpplague, Here's that TI programmer I was talking about http://www.ti.com/tool/usb-to-gpio
  • [03:34:49] <mdp> bbt
  • [03:35:17] <Russ> It implements PMBUS with GPIOs. The main problem would be if there was a flyswatter board, it wouldn't work with the TI provided software
  • [03:35:29] * prpplague looks
  • [03:36:27] <Russ> the interface is basic, they have some fets that can turn on and off pullups for some of the GPIOs, one with varying strength
  • [03:36:44] <Russ> er, two with varying strength
  • [03:36:56] <prpplague> Russ: you opened it up to see whats inside?
  • [03:37:10] <Russ> no, there is a schematic in the datasheet
  • [03:37:40] <prpplague> ahh
  • [03:37:43] <prpplague> dandy
  • [03:37:52] <prpplague> Russ: i'll look it over
  • [03:38:34] <prpplague> oh it is using the TUSB3210
  • [03:38:46] <Russ> To replicate the actual product, you'd need 13 GPIOs, unless you fix the pullup functionality with jumpers, then only 8
  • [03:39:26] <prpplague> Russ: i'll have to look over this to see what we can do
  • [03:39:53] <Russ> I wouldn't have time to write my own software, so that would be an issue
  • [03:40:02] <prpplague> (this is one of those items i'll have to dream about during my commute)
  • [03:40:28] <Russ> does the flyswatter have configurable pullup/pulldown functionality onboard?
  • [03:40:30] <prpplague> Russ: which features are you targeting? gpio or one of the other bus protocols?
  • [03:40:44] <Russ> I'd have to check the ucd9220 datasheet
  • [03:41:07] <prpplague> Russ: not directly, but we are already looking at a rev of the f2 to add some additional features
  • [03:41:48] <prpplague> freakin ds2 gave everyone at ELC the flu, bad ds2 , bad ds2
  • [03:41:58] <Russ> hmm..straight jtag is another option on the ucd9220, but then I don't think you get a read out of stats while it is running
  • [03:42:42] <prpplague> Russ: let me bookmark that too and start reading on it
  • [03:43:16] * userx- (~0x-@unaffiliated/userx-) Quit (Ping timeout: 252 seconds)
  • [03:43:19] <Russ> prpplague, if you want to try to get funding for it, I think it'd be awesome to make a set of LD_PRELOADable modules that would allow the flyswatter to emulate other devices
  • [03:43:37] <Russ> most of the other devices probably use libusb on linux
  • [03:44:05] <prpplague> Russ: yea, we are considering a more robust usb "gadget" with a FPGA core to do some interesting stuff
  • [03:44:16] <jay6981> biological warfare?
  • [03:44:18] <Russ> ah, emulation on the actual hardware side
  • [03:44:46] <Russ> it'd be more hinky, but you'd probably spend a lot less time doing it on the LD_PRELOAD side
  • [03:46:01] <prpplague> Russ: yea, there are some things we want to do, basically something akin to the bus pirate but on steroids..... ARGH!

  • [13:21:18] <jwinnebeck> But I realized, this isn't the repository from setup-scripts
  • [13:21:35] <jwinnebeck> it uses one "meta-texasinstruments" mapped as meta-ti locally
  • [13:21:46] <koen> right
  • [13:21:56] <koen> that github one is a staging area
  • [13:21:57] <jwinnebeck> koen: what is the relationship of your repo to the one that comes from the "official" (??) place
  • [13:22:16] <koen> I send patches to the meta-ti mailinglist, denix will pull them in
  • [13:22:17] <jwinnebeck> oh so those patches are pushed to the one that I see (eventually)?
  • [13:22:19] <jwinnebeck> ok
  • [13:22:28] <koen> except that denix has the ELC plague, so he's home sick
  • [13:22:33] <jwinnebeck> ELC?
  • [13:23:08] <koen> https://events.linuxfoundation.org/events/embedded-linux-conference
  • [13:23:14] <jwinnebeck> ah
  • [13:23:29] <jwinnebeck> ok, i was surprised the other day when I updated and didn't get that commit
  • [13:24:34] <SilicaGel> ok
  • [13:24:38] <jwinnebeck> We have to make a patch today
  • [13:24:41] <jwinnebeck> SilicaGel and I
  • [13:24:41] <Crofton|work> what are the plague symptoms?
  • [13:24:51] <SilicaGel> koen we have a patch we need added to clock33xx_data.c
  • [13:24:57] <jwinnebeck> and the patch will want to go into meta-ti
  • [13:25:02] <SilicaGel> the actual code of the patch came from a dude at texas instruments named amit or TK or something
  • [13:25:03] <jwinnebeck> well "meta-texasinstruments"
  • [13:25:06] <ynezz> lol
  • [13:25:21] <ynezz> (sorry)
  • [13:25:26] <SilicaGel> ynezz: well there were two guys, one named amit and the other named TK, I just can't remember which one it was
  • [13:25:28] <av500> ynezz: no problem
  • [13:25:43] <av500> so, 2 guys at TI and 2 guys here, all holding one patch
  • [13:25:57] <SilicaGel> yeah, and it's the same patch
  • [13:25:59] <SilicaGel> isn't that awful?
  • [13:26:20] <jwinnebeck> Well, sort of, if we do it, it looks like from what's there the actual patch would be to add a patch 22 into meta-ti
  • [13:26:20] <koen> Crofton|work: flu like
  • [13:26:38] <jwinnebeck> because the kernel isn't in the OE repos
  • [13:26:39] <SilicaGel> Actually the T.I. guys sent me 7 patches total, but when I looked, I found that in the latest angstrom only 1 of them is actually necessary now
  • [13:26:39] <Crofton|work> nose congestion is what I have
  • [13:27:54] <ynezz> hm, 5 people, 18 patches, but no cluestick? :p
  • [13:28:02] <jwinnebeck> Well based on what koen said the proper way is to send the patch to the meta-ti mailinglist and hope denix picks it up

  • [13:28:21] <koen> you can funnel kernel patches thru me if that's easier
  • [13:28:37] <SilicaGel> okay well
  • [13:28:40] <jwinnebeck> It could be yeah, but then we would want to clone your repo?
  • [13:28:41] <SilicaGel> i guess amybe we should try it first HAHA
  • [13:28:50] <jwinnebeck> Right now I have meta-texasinstruments cloned
  • [13:29:25] <jwinnebeck> or if I make a commit to that repo and send you that patch it's close enough? I'm still new to git, but learning enough that I'm starting to understand it
  • [13:29:42] <jwinnebeck> I spent a few hours yesterday reading the whole user guide and tutorial
  • [13:30:10] <jwinnebeck> But yeah SilicaGel and I should just get the patch working then we'll go from there
  • [13:30:18] <jwinnebeck> we just need to add 1 file
  • [13:30:29] <SilicaGel> it's a short patch. My problem is that the patch is for a file that doesn't exist any more, clock33xx.c
  • [13:30:45] <jwinnebeck> SilicaGel don't worry about taht. Just let me know when you're ready to work on it
  • [13:30:47] <SilicaGel> so I think we need to make 2, 2-line additions to clock33xx_data.c and add two functions
  • [13:31:07] <SilicaGel> that's true, we can let this mysterious denix person figure that out
  • [13:31:12] * bradfa (~bradfa@173.225.52.244) has joined #beagle

  • [13:31:39] <ynezz> ah, 6 people and still counting...
  • [13:31:59] <ynezz> you should google for "submitting patches/work" or "git patch workflow" for additional information
  • [13:32:19] <ynezz> probably there's something already for OE/yocto
  • [13:33:09] <jwinnebeck> Yeah I already read up on that
  • [13:33:20] <ynezz> at least I remember reading it somewhere, including the pull requests (which I think it's preferred way)
  • [13:33:21] <jwinnebeck> Just not specific to OE
  • [13:33:35] <jwinnebeck> Yeah to do a pull request you need a public repo tho
  • [13:33:43] <jwinnebeck> This will probably be our own patch... so
  • [13:33:45] <ynezz> github is cheap
  • [13:33:46] <jwinnebeck> maybe not worth it

  • [13:39:53] <mdp> oh good
  • [13:40:01] <SilicaGel> But it leaves the PRUSS in reset meaning you get a bus error if you try to access it in ANY way
  • [13:40:16] <SilicaGel> I've been doing all my testing by using devmem2 to activate it
  • [13:40:16] <mdp> when you were doing stuff in userspace, I had wondered if our am335x kernel fork didn't have the PRU hwmod/clock data
  • [13:40:35] <mdp> I kinda assumed that to be the case since we've neglected PRU support in general :)
  • [13:40:42] <SilicaGel> who is "our" ... ? It's there. It's seriously broken in the linuxsdk
  • [13:40:49] <SilicaGel> it's mostly correct in angstrom
  • [13:41:12] <mdp> I think the issue there is that the sdk was released a long time ago, except the recent minor update
  • [13:41:20] <SilicaGel> yeah
  • [13:41:41] <mdp> and koen has been updating the angstrom kernel off of patches in the PSP staging tree for additional functionality
  • [13:41:43] <SilicaGel> the pruss userspace side of the driver (the library really) is also broken, but I have an update that I'm trying to test now (except my app won't link and I have no idea why)
  • [13:42:02] <SilicaGel> pruss is really really close to working out of the box on am335x though

  • [15:02:03] <ynezz> I would read that commit message (for libpcre)

  • [15:03:43] <koen> jwinnebeck: and yeah, mad rush type of deal
  • [15:04:25] <jwinnebeck> and since it appears to be standard practice to including specific revisions of code in the bb, if someone decides to "upgrade" foobar 1.0 to 2.0, the bb would change because the commit/tag/branch/whatever would change...

  • [15:07:35] <av500> you do
  • [15:07:36] <koen> for the oe stuff, it's only builddescriptions and patches
  • [15:07:38] <jwinnebeck> the manual and everything else seems to suggest that once you git clone, you don't need to touch the source anymore
  • [15:07:47] <koen> for other things, git clone will get you everything
  • [15:08:01] <jwinnebeck> Yeah I notice the oe is just bbs and patches and stuff I get that
  • [15:08:12] <jwinnebeck> but my git clones of the meta-* is really the complete repository?
  • [15:08:26] <jwinnebeck> that seems odd, something like the kernel is massive, and git was basically made for the Linux kernel
  • [15:08:43] <jwinnebeck> it seems odd to be downloading the entire kernel history tree to get the code
  • [15:08:49] <av500> yes, the clone holds it all
  • [15:09:21] <koen> jwinnebeck: the clones of meta-* are the complete repo, but they don't have the sources for the things they build, like the kernel
  • [15:09:33] <jwinnebeck> koen: yeah I got that, because of the do_fetches
  • [15:09:35] <jwinnebeck> it's just the pointers
  • [15:09:45] <ynezz> cooking recipes
  • [15:09:50] <jwinnebeck> but when it fetches the Linux kernel from git, it's cloning the whole kernel repo?
  • [15:09:58] <koen> yes
  • [15:10:13] <jwinnebeck> so wouldn't that be GBs in size?
  • [15:10:25] <koen> less than 1GB
  • [15:10:26] <jwinnebeck> I have a SVN repo, sometimes people love to check in 100MB files
  • [15:10:30] <koen> git compresses quite well
  • [15:10:38] <koen> svn is stupid :)
  • [15:10:44] <jwinnebeck> ha
  • [15:10:45] <ynezz> or the admin :)
  • [15:10:55] <koen> it keeps a full copy of revision N and N-1
  • [15:11:14] <koen> so svn diff is fast for 1 rev down, but will hit the server for older revs
  • [15:11:23] <jwinnebeck> Well people aren't supposed to do it, but if someone checks in some massive file, maybe they decide to delete it because they don't need a 2GB systemd-image tarball in SVN, it's "forever" there
  • [15:11:32] <ynezz> there are hooks, so you could prevent it at all
  • [15:11:46] <jwinnebeck> in git would that mean anytime someone cloned, you'd be downloading this 2GB tarball for the rest of time?
  • [15:11:46] <mru> a random kernel tree here has a .git of ~500MB
  • [15:12:32] <jwinnebeck> We use svn here on a server I've set up, and we have one big repo with a crap ton of projects. Normally one only checks out a small subset of that, and within a team might only need a small subset. I guess in the git world each "project" would be a separate repository.
  • [15:12:49] <jwinnebeck> But SVN is nice in that it tracks file histories if they move/copy between projects
  • [15:12:52] <mru> svn repos typically have insane setups
  • [15:13:06] <jwinnebeck> But in git you can keep history but it's only on the commits, right?
  • [15:13:28] <jwinnebeck> if I wanted to copy a file foo.c from some other git repo into mine, the link of history, it would be broken, no?
  • [15:13:29] <koen> right
  • [15:13:32] <koen> MacBookAir-2:linux koen$ du -hs .git
  • [15:13:32] <koen> 1,7G .git
  • [15:13:34] <av500> right
  • [15:13:55] <jwinnebeck> So that sucks, if I wanted to fork a part of a project, the history of the code is gone
  • [15:14:03] <mru> koen: you've probably been mucking about in that repo
  • [15:14:17] <mru> if you flushed all reflogs and ran a gc it would shrink
  • [15:14:31] <jwinnebeck> I would need to fork an entire project and then delete the majority of files?
  • [15:14:32] <koen> likely
  • [15:14:42] <mru> there is filter-branch
  • [15:14:50] <koen> it has a ton of remotes as well
  • [15:14:51] <av500> jwinnebeck: it all depends on what you call one "project"
  • [15:15:22] <av500> i guess you have one massive svn and ppl checkout subfolders
  • [15:16:00] <jwinnebeck> That's how our svn works now
  • [15:16:13] <av500> we had that for our android stuff
  • [15:16:21] <av500> svn up was a pain for the remote people
  • [15:16:31] <av500> took svn like 15min to make up its mind what to update
  • [15:16:31] <jwinnebeck> Well we are a local team within one building
  • [15:16:45] <jwinnebeck> if I was doing a public, distributed project, I would not use svn
  • [15:16:46] <av500> because it was md5summing all of it
  • [15:16:49] <jwinnebeck> I would use git :)
  • [15:16:54] <av500> and all the network latency
  • [15:16:57] <jwinnebeck> even though I don't know git yet
  • [15:17:01] <ynezz> I wouldn't touch svn again
  • [15:17:18] <av500> ynezz: my grumpy coworker would
  • [15:17:18] <ynezz> I would rather use suicide booth
  • [15:17:31] <mru> I only touch svn through git-svn
  • [15:17:37] <jwinnebeck> Well for example, let's say I love Apache Ant. Apache Ant has in it an awesome set of classes for creating and managing ar and tar files. Let's say someone would want to put that in their project, or make a separate library that just does tar files. And if Ant was git... Is there a way to "fork" that? It seems that the best solution is just copy/paste files and break the history
  • [15:17:40] <av500> I told him to write a git wrapper that would behave like svn commit
  • [15:17:59] <jwinnebeck> In SVN you would have to do this as well, of course, but git seems to want to solve the problem of braching other people's repos
  • [15:18:30] <jwinnebeck> However, in a single org, with a single SVN repo, then you don't have to break that history
  • [15:18:36] <mru> git assumes you are capable of putting separating things in separate repos
  • [15:18:47] <ynezz> you can export that history along with the file
  • [15:18:51] <mru> if your mind is all a-jumble, you probably shouldn't be using git
  • [15:18:57] <ynezz> read about git harder :)
  • [15:18:59] <jwinnebeck> Yeah but think of something like the kernel, the kernel is really one project and thousands of tiny projects in it
  • [15:19:00] <mru> nor should you be writing software in the first place

  • [15:19:35] <av500> it could
  • [15:19:42] <jwinnebeck> But no one made separate git repos for every kernel driver

  • [15:20:32] <av500> xactly
  • [15:20:41] <jwinnebeck> For now
  • [15:20:44] <jwinnebeck> but eventually it won't scale
  • [15:20:45] <av500> jwinnebeck: every driver in the world has to be in one massive git
  • [15:20:46] <ynezz> forever
  • [15:20:50] <jwinnebeck> what happens 10 years for now
  • [15:20:53] <av500> because there is no API

  • [15:21:04] <av500> if there was a binary API, driver could be anywhere

  • [15:21:57] <jwinnebeck> although it solves the problems for the "leaf" users that just want to compile the HEAD
  • [15:22:45] <av500> git clone on the kernel is fast
  • [15:22:52] <av500> so why bother with shallow
  • [15:22:58] <jwinnebeck> But it's still bad for refactoring, what if someone decides that all of the ARM arch and all of the ARM hardware drivers should be in a separate repo. Now all history is lost, which is a catastrophie for the open source license and copyright tracking

  • [15:25:45] <qing> about the relocation~~
  • [15:25:56] <jwinnebeck> OK so git filter-branch is like the way you can do filtering with svn, basically you create a new repository by rebuilding each commit, potentially modifying the commit along the way to just the files you need
  • [15:26:37] <jwinnebeck> I wonder if it fails as spectacularly as SVN when the subdir is called "foo" now but it was called "bar" earlier
  • [15:27:02] <qing> does u-boot using the "position independent code" to implement the relocation feature?

  • [17:46:51] <SilicaGel> adding a clkops that adds two method calls:

  • [17:46:59] <SilicaGel> .disable = am33xx_icss_clk_disable,
  • [17:47:12] <SilicaGel> so that when the clock gets activated, those methods get called
  • [17:47:22] <SilicaGel> then, obivously, adding those methods. The enable loks like this:
  • [17:47:35] <SilicaGel> omap2_prm_clear_mod_reg_bits(AM33XX_ICSS_LRST_MASK, AM33XX_PRM_PER_MOD, AM33XX_RM_PER_RSTCTRL_OFFSET);
  • [17:47:42] <koen> I'm so happy people are actually trying to use the PRUss
  • [17:47:50] <koen> and tell me when I screw up the kernel again :)
  • [17:47:53] <SilicaGel> which is the same as writing it into the reset module
  • [17:47:57] <SilicaGel> dude no man
  • [17:47:59] <SilicaGel> it's very very very very close
  • [17:48:06] <jay6981> ok. i was a bit confused because there's a seperate reset bit for the PRUSS
  • [17:48:16] <jay6981> but to hold that in reset, you'd have to continually write 1 to it
  • [17:48:17] <SilicaGel> the pruss kinda has 3 resets
  • [17:48:18] <SilicaGel> well
  • [17:48:28] <SilicaGel> the PRUSS has one master reset, and each PRU has its own reset.
  • [17:48:39] <jay6981> makes sense
  • [17:48:46] <jay6981> matroskha dolls :)
  • [17:49:02] <SilicaGel> The problem with the software as is, simply put, is that when the PRUSS is in reset in the PRM_PER_MOD (i.e. the mast reset module up at 0x44000000 or something) ...
  • [17:49:07] <SilicaGel> the PROBLEM is that when it's in reset, it can't talk on L3 or L4
  • [17:49:20] <SilicaGel> so you just get bus errors and can't go further until you release it from reset
  • [17:49:22] <jay6981> yeah, because it's interface clocks aren't driven
  • [17:49:23] <SilicaGel> that's waht our patch does
  • [17:49:26] <jay6981> so it's not on the bus
  • [17:49:31] <SilicaGel> right
  • [17:49:50] <SilicaGel> I wrote a tiny PRU program, it writes 0xDEADBEEF into PRU data memory, and then it counts
  • [17:49:54] <SilicaGel> count count count up up up
  • [17:49:59] <SilicaGel> ...... and IT WORKS
  • [17:50:12] <jay6981> great

  • [17:51:06] <SilicaGel> Yeah
  • [17:51:11] <SilicaGel> there's a CYCLES register in each PRU ...
  • [17:51:16] <jay6981> sweet!
  • [17:51:21] <SilicaGel> what you do is when you reset it, you write 0x0A to the control register instead of 0x02
  • [17:51:33] <SilicaGel> OR your pru program tiself can just turn on the counter
  • [17:51:37] <koen> SilicaGel: if you get it working, please base your patches on top of that, that would make it easier to get into the factory kernel
  • [17:51:42] <SilicaGel> the coutner only counts up to 4 billion then it latches at 0xFFFFFFFF
  • [17:51:52] <SilicaGel> koen: crap. haha. Ywe need to tell jwinnebeck that
  • [17:51:56] <jay6981> SilicaGel: see??? now you have TI support :)
  • [17:52:01] <SilicaGel> I just stood behind him and told him what to change
  • [17:52:25] <SilicaGel> koen: it's working except it doesn't put it back into reset when you rmmod uio_pruss. I don't understand clock trees enough yet.
  • [17:52:42] <SilicaGel> Can somebody write me a program that analyzes the clock and power domaint rees and outputs them in graphviz?
  • [17:52:49] <SilicaGel> ... too ... many .... files
  • [17:52:51] <SilicaGel> :)
  • [17:53:18] <SilicaGel> prussdrv (the userspace library) also has problems that I am fixing.
  • [17:53:32] <SilicaGel> I might just fork their pruss userspace driver and put it up on my google code
  • [17:53:48] <jay6981> SilicaGel: maybe you should look at the clock tree tool for omap35xx
  • [17:53:59] <jay6981> different SoC, but it might help illustrate whats going on
  • [17:54:01] <SilicaGel> there's ... a clock tree tool? huh.
  • [17:54:18] <jay6981> it's on the omap35xx ti page
  • [17:54:21] <jay6981> where you get the TRM
  • [17:54:54] <jay6981> won't help with the kernel api though
  • [17:54:55] <SilicaGel> i'm tryign to decide whether or not I want to really understand this clock tree stuff or not. I'm really curious about it. But maybe I really don't NEED to fully understand it, I certainly ahve enough things to do as it is
  • [17:55:06] <SilicaGel> i'll think about that.
  • [17:55:07] <jay6981> you've almost got it i think
  • [17:55:21] <SilicaGel> right now I'm tryign to figure out why their examples are all referring to registers like ECR2 which don't exist haha
  • [17:55:29] <jay6981> sometimes seeing a diagram can really pull concepts together
  • [17:55:36] <SilicaGel> yeah definitely
  • [17:55:44] <SilicaGel> does this tool generate source code, kind of like the pinmux tool does?
  • [17:56:12] <jay6981> no
  • [17:56:21] <jay6981> sort of a simulation
  • [17:56:34] <av500> jay6981: here: http://www.myrddin.de/files/diagram.jpg
  • [17:56:37] <jay6981> you set the registers and you can see what clocks result
  • [17:57:42] <jay6981> is that for some MMO game?

  • [18:00:03] <Guest78721> can someone tell me if the beaglebone angstrom demo distribution has iptables support?
  • [18:00:45] <Guest78721> when i execute "iptables -L" i get: iptables v1.4.12.2: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.
  • [18:01:39] <SilicaGel> i'd be absolutely shocked if those modules didn't exist and were compiled
  • [18:01:44] <av500> jay6981: i haz no idea
  • [18:02:32] <Guest78721> having iptables support in any linux distribution that supports networking seems fundamental to me

What I did is make a .patch file and put it into the linux-ti33x-psp-3.2/ directory
  • [18:11:14] <jwinnebeck> then I modified linux-ti33x-psp_3.2.bb to add a line to that patch
  • [18:11:36] <jwinnebeck> I did this in my git clone of meta-texasinstruments that I got from the angstrom layers.txt
  • [18:11:51] <jwinnebeck> I haven't committed yet, but that would normally be my next step
  • [18:12:03] <koen> jwinnebeck: pretty much the same
  • [18:12:05] <jwinnebeck> I figured after I commit I would push that somewhere, somehow

  • [18:15:39] <woglinde> jwinnebeck thats a common workflow
  • [18:15:39] <jwinnebeck> If I do that then when I do my angstrom builds it won't have my mods in it
  • [18:15:45] <woglinde> man git-sendmail
  • [18:15:50] <jwinnebeck> yeah I see that
  • [18:15:59] <jwinnebeck> I'm just trying to figure out what git to start from
  • [18:16:08] <woglinde> o.O
  • [18:16:21] <jwinnebeck> once I get the commit I saw the tool to get it sent out
  • [18:16:32] <woglinde> only backdraw is that git-sendmail cannot make a coverletter on the fly
  • [18:16:43] <woglinde> till later
  • [18:16:45] <Guest78721> if anyone has a moment could they check and see if they have iptable_filter.ko on their beagle(bone) angrstom distribution?
  • [18:16:49] <jwinnebeck> Well there is another command to make something I would put into a mail
  • [18:16:52] * Daniel___ (~Daniel@nat/ti/x-solpgkrdluuentwh) has joined #beagle
  • [18:17:07] <woglinde> you can use first git format-patch
  • [18:17:18] <woglinde> which can do a coverletter
  • [18:17:28] <woglinde> and than use git sendmail to send all the stuff
  • [18:17:29] <jwinnebeck> I don't have that ko Guest78721, but I would think it's compiled in because there aren't many modules
  • [18:17:32] <woglinde> now really till later
  • [18:17:46] <jwinnebeck> ok woglinde, I have to get a commit first :)
  • [18:17:52] <jwinnebeck> The sending of the commit I'm not worried about
  • [18:18:11] <jwinnebeck> koen says I'm supposed to base off this: https://github.com/koenkooi/linux/tree/linux-ti33x-psp-3.1-r2l+gitr1d84d8853fa30cf3db2571a5aec572accca4e29d
  • [18:18:39] <jwinnebeck> So what does that mean? git clone that and then reapply my changes manually to that, commit and then send the patch (sendmail, etc)
  • [18:18:51] <Guest78721> compiled into the kernel? but ip_tables.ko is not? and even after loading ip_tables.ko, "iptables -L" still complains about not being able to initialize the filter table
  • [18:18:54] <hsyed> I am trying to use gpio 150 for a custom push button but when I do [#echo 150 > export] nothing happens (no errors no gpio150 directory), pin mux in (x-loader) has GPIO 150 set up as GPIO, Any suggestion, Please

  • [19:25:45] <SilicaGel> ok
  • [19:25:47] <jwinnebeck> and barely that
  • [19:25:52] <SilicaGel> let's get a better compile then!
  • [19:26:03] <jwinnebeck> I should have one! whatever one I used to build the kernel I've already tested
  • [19:26:16] <jwinnebeck> I already tested meta-ti, I just hope this kernel works
  • [19:26:23] <jwinnebeck> testing 2 kernels now

  • [20:31:49] <woglinde> write one

  • [20:32:23] <jay6981> write one in pru assembly :P
  • [20:32:28] <aholler> explore it via jtag ;)
  • [20:32:43] <SilicaGel> no, i'm tryin to copy the first 4 words of DMEM0 into registers r8, r9, r10, r11:
  • [20:33:04] <SilicaGel> XOR r0, r0, r0 // set r0 <= 0x00000000
  • [20:33:04] <SilicaGel> LBBO r8, r0, 0, 16
  • [20:33:19] <SilicaGel> but they're ending up in r9 - r11

  • [20:33:57] <jwinnebeck> sounds like an indexing problem to me
  • [20:34:03] <jwinnebeck> starting from 1 isntead of 0
  • [20:34:06] <SilicaGel> LBBO is: LBBO REG1, rn2, offset, length
  • [20:34:32] <SilicaGel> yeah. except the offset is 0. and there's no indexing on the destination.
  • [20:34:37] <SilicaGel> look at their example:
  • [20:34:55] <SilicaGel> lbbo r2, r1, 5, 8 // Copy 8 bytes into r2/r3 from the memory address r1+5
  • [20:35:30] <SilicaGel> LBBO copies a block of ram into a register (in thier example r2) and then the following registers if the count is > 4
  • [20:35:51] <SilicaGel> so their r2, r1, 5, 8 means copy into r2 + r3
  • [20:36:01] <SilicaGel> my r8, r0, 0, 16 should copy into r8, r9, r10, r11

  • [20:45:53] <SilicaGel> then I used the shell's printf to be able to spit those back out in hex.

  • [22:00:28] <mranostay> heh
  • [22:00:40] <mranostay> *ahem* mdp :)
  • [22:00:49] <mranostay> mattzz: which tree are you using?
  • [22:01:04] <mattzz> rcn, 3.3-rc1
  • [22:01:31] <mattzz> (3.2.0-psp2)
  • [22:01:32] <mranostay> yeah that is version but which tree did you clone?
  • [22:02:25] <mattzz> I am using rcn's build_kernel.sh. It does all the magic. Let me check.
  • [22:04:22] <mattzz> I think it's basically 3.3-rc1 plus a ton of patches from arago
  • [22:08:36] <mattzz> new kernel boots fine, I can mod probe st7735fb and all the depending modules (sysfillrect etc.) are being loaded as well.
  • [22:10:04] <mattzz> I guess doing 'mknod /dev/fb0 c 29 0' should not be necessary, right?

  • [22:18:14] <Sharpyuk> I've managed to find the 3 files I was looking for, but now it requires the path to the kernel source files
  • [22:18:54] <Sharpyuk> so I've got to the bottom of the instructions here: http://support.robotis.com/en/techsupport_eng.htm#software/dynamixel_sdk/usb2dynamixel/usb2dxl_linux.htm
  • [22:19:19] <Sharpyuk> and at the stage where I'm trying to do the 'make'
  • [22:19:32] <Sharpyuk> to compile the code..
  • [22:20:10] <xxiao> obls sniffer does not come with probe cable?
  • [22:20:28] <Sharpyuk> I'm using a windows pc, and transferring files with WinSCP
  • [22:21:31] <Sharpyuk> anyone got any clues on how to download the entire kernel using windows?
  • [22:22:07] <xxiao> ? you mean source tree? use git on windows or download the released tarball
  • [22:22:30] <ynezz> and then crosscompile it on windows :)
  • [22:22:34] <_av500_> are you going to compile the kernel on windwos?
  • [22:23:11] <Sharpyuk> no, I will transfer it to the beagebone.. then just compile the ftdi_sio driver
  • [22:23:22] <Sharpyuk> but it requires lots of other files to compile
  • [22:23:32] <jwinnebeck> if you really want to compile, you might want to look into an Ubuntu VM...
  • [22:23:37] <jwinnebeck> or other linux
  • [22:23:54] <jwinnebeck> but you need a lot of RAM and space, although if you can find a way to just do the kernel...
  • [22:24:24] <Sharpyuk> yeah I could do that, but I'm hoping it will be simple to compile this one driver without..
  • [22:24:28] <_av500_> didnt kone post some git url today?

  • [22:24:42] <jwinnebeck> Yeah he did, you can compile that kernel, I did run it on the beaglebone
  • [22:24:43] <_av500_> koen even
  • [22:24:58] <Sharpyuk> git://arago-project.org/git/projects/linux-am33x.git;protocol=http;branch=v3.2-staging
  • [22:24:58] <jwinnebeck> The only other ones I've gotten to work is the TI SDK and the one from bitbake
  • [22:25:05] <jwinnebeck> but the bitbake one does from everything
  • [22:25:12] <_av500_> https://github.com/koenkooi/linux/tree/linux-ti33x-psp-3.1-r2l+gitr1d84d8853fa30cf3db2571a5aec572accca4e29d
  • [22:25:31] <Sharpyuk> I have worked out how to download individual files, but that would take some time
  • [22:25:38] <jwinnebeck> Yeah my information to you is probably out of date Sharpyuk... I gave you literally the source, but the angstrom applies a lot of patches
  • [22:25:52] <jwinnebeck> I hate to say it but you might want to start from koen's instead
  • [22:26:09] <jwinnebeck> You still need a toolchain to compile it though, I don't know the proper way to do that
  • [22:26:10] <_av500_> koen's is PSP + patches
  • [22:26:27] <jwinnebeck> I got mine via bitbake, but the bitbake method also compiles everything else on your bone image
  • [22:26:39] <Sharpyuk> I can compile on the beaglebone, just need to transfer the files that are required
  • [22:26:43] <jwinnebeck> and again it all requires Linux
  • [22:26:50] <jwinnebeck> if there's a way to get it to work on cygwin I don't know
  • [22:26:58] <_av500_> what is dynamixel anyway?
  • [22:27:04] <Sharpyuk> mmm, it may be overkill
  • [22:27:06] <jwinnebeck> Well if you have a compiler there... if the bone has enough RAM to compile a kernel...
  • [22:27:16] <jwinnebeck> If you have a compiler there, then what is the problem?
  • [22:27:19] <Sharpyuk> they're servos used for robotics
  • [22:27:31] <jwinnebeck> copy the source code there are run make install_modules and make install

  • [22:27:49] <jwinnebeck> but still, if you used the arago kernel without patches I don't know how well it will work
  • [22:28:06] <Sharpyuk> I'm new to linux and more used to programming microcontrollers..
  • [22:28:38] <Sharpyuk> I've only used 3 files.. ftdi_sio.c - ftdi_sio.h - usb-serial.h
  • [22:28:49] <jwinnebeck> Well you have all of the other files right?
  • [22:28:56] <jwinnebeck> you should have the whole kernel tree with those modified files?
  • [22:28:59] <Sharpyuk> but there's lots of header files required
  • [22:29:07] <ynezz> oh really? :)
  • [22:29:09] <jwinnebeck> if you have a compiler on the bone like you said, then run it
  • [22:29:12] <mattzz> hm, http://www.angstrom-distribution.org down?
  • [22:29:13] <ynezz> it's not msp430...
  • [22:29:20] <Sharpyuk> I only downloaded the 3 files
  • [22:29:22] <jwinnebeck> Sharpyuk: the entire kernel is required those are just 3 files in the kernel
  • [22:29:27] <jwinnebeck> OK then you aren't even close...
  • [22:29:31] <jwinnebeck> you need the whole kernel

  • [22:29:38] * pcacjr (pcacjr@nat/indt/x-ksarqhetffddepqx) has joined #beagle

  • [22:30:16] <jwinnebeck> well there is a way to just compile modules I guess, but I don't know how I'm not an expert in that
  • [22:30:19] <Sharpyuk> ah I see.. wow, that's a pretty major undertaking then..
  • [22:30:23] <jwinnebeck> you still need all of the headers and source though
  • [22:30:32] <jwinnebeck> Well it's not a hard one, just a bigger one
  • [22:30:41] <jwinnebeck> you git clone the whole thing, I would use the koen link
  • [22:30:45] <jwinnebeck> and you need a compiler
  • [22:30:49] <jwinnebeck> and make and such
  • [22:30:54] <Sharpyuk> yeah looking at the link it should be possible to just compile this one driver, but could be wrong
  • [22:30:56] <jwinnebeck> but you seem to imply that you have this on the bone already
  • [22:31:07] <jwinnebeck> Well if they told you how, then you can get the headers from the source anyway
  • [22:31:15] <Sharpyuk> yeah I have run 'make' but it comes up with an error
  • [22:31:18] <jwinnebeck> so getting the whole source tree doesn't help
  • [22:31:22] <jwinnebeck> I mean doesn't hurt
  • [22:31:54] <Sharpyuk> yeah I will try and download git and see if that will allow me to download the entire kernel so I can get the files I need
  • [22:32:20] <Sharpyuk> thanks for your help, no doubt I will be back if I get stuck.. much appreciated
  • [22:32:22] <jwinnebeck> ok unfortuantely I've got a go now, but good luck.

  • [23:00:56] <koen> 8 on my i7
  • [23:01:09] <koen> I ran into the gcc patch problem on my core2quad
  • [23:01:18] <_av500_> koen: on the atom, has the 3rd thread started yet? :)
  • [23:01:20] <koen> no other problems sprint to mind
  • [23:01:34] <ynezz> then git-native, elfutils-native etc.
  • [23:01:35] <koen> _av500_: heh
  • [23:01:49] <ynezz> I'm using 4 for a long time
  • [23:01:49] <koen> _av500_: it does take 48h to build 3 filesystems, about 6 hours onthe i7
  • [23:02:40] <ynezz> but just today it seems to be broken a lot due to the more bb threads

  • [23:06:21] <koen> maybe that made the problem wors

  • [23:06:36] <koen> as always: complain on the mailinglist, maybe someone is sitting on a patch
  • [23:07:05] <koen> ynezz: yes, the gcc recipes share a single srcdir now, so when 2 recipes run do_patch at the same time -> boom
  • [23:07:16] <ynezz> d'oh

  • [23:23:49] <mru> the kernel, the whole kernel, and nothing but the kernel?
  • [23:23:58] <_av500_> a kernel of truth
  • [23:24:09] <mru> somehow I anticipated that
  • [23:24:11] <Sharpyuk> good question, is that a link to the entire kernel?
  • [23:24:26] <_av500_> its the wrong link anyway
  • [23:24:29] <_av500_> use the github one
  • [23:24:39] <Sharpyuk> do you have a link to that one?
  • [23:25:01] <Sharpyuk> is it this one? https://github.com/koenkooi/linux/tree/linux-ti33x-psp-3.1-r2l+gitr1d84d8853fa30cf3db2571a5aec572accca4e29d

  • [23:27:42] <Sharpyuk> how can I download the whole thing, it shows me a list of the files.. but I don't want to download the all individually
  • [23:28:05] <aholler> git clone
  • [23:28:40] <Sharpyuk> I'm using windows

  • [23:28:59] <_av500_> yes, you said silly
  • [23:29:17] <Sharpyuk> i downloaded that too
  • [23:29:53] <Sharpyuk> but I try to open a git repository and type in the url above, it comes up with an error saying that it's not a valid repository
  • [23:30:06] <_av500_> Sharpyuk: do you see the icon that says "Zip"
  • [23:30:37] <Sharpyuk> yup
  • [23:30:40] <Sharpyuk> found it
  • [23:30:47] <_av500_> it does not mean zip code :)
  • [23:30:48] <aholler> git read-only is the correct icon
  • [23:30:50] <Sharpyuk> I presume I click on that one..
  • [23:30:58] <Sharpyuk> lol
  • [23:31:10] <_av500_> yes, it zips up the code

  • [23:35:35] <_av500_> the kernle does not care in which folder it is
  • [23:35:50] <_av500_> aholler: kernle is a small kernel, no?

  • [23:36:25] <aholler> av500: the psp one? must be since it is portable
  • [23:36:25] <_av500_> files have been edited

  • [23:36:57] <_av500_> gee, way past midnight, must turn back into a pumpkin.....
  • [23:37:28] <Sharpyuk> this is part of the driver I've updated for ftdi_sio which I'm trying to compile.. it requires the kernel files

  • [23:41:05] <Sharpyuk> and it gives error - make[1]: *** No rule to make target `modules'. Stop.
  • [23:41:44] <Sharpyuk> so I need to know which files I need to copy to the /usr/src/linux-3.1.0 folder
  • [23:42:24] <Sharpyuk> I've copied all the includes I thought would be required, but it looks like it needs more modules
  • [23:42:29] * siegen (~lechaguin@sign-4d094cda.pool.mediaWays.net) Quit (Quit: Leaving)
  • [23:42:44] <aholler> it needs a whole kernel there
  • [23:42:52] <thurbad> if it's just modules on it's own then the pwd step may have failed
  • [23:43:32] <Sharpyuk> ok so I copy the contents of the zip into that folder then

  • [23:55:38] <thurbad> lots of little files that never even get included in the build
  • [23:55:52] <Sharpyuk> yes, I suspect so
  • [23:56:35] <Sharpyuk> hope the whole kernel will fit on the memory card
  • [23:56:38] <Sharpyuk> lol
  • [23:56:53] <thurbad> how big is your card?
  • [23:57:19] <Sharpyuk> not sure, never checked.. its the standard one which comes with the beaglebone
  • [23:58:20] <Sharpyuk> is there a command I can run to check the disk space?
