[00:08:55] zz_prtksxna is now known as prtksxna
[00:09:22] <cradek> I don't approve of skunkworks_ not being here and testing right away
[00:10:42] <jepler> So when I command gpio 24 to be a true output, I get 83 c2 00 10 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00
[00:10:52] <jepler> (dunno if I wrote the right number of 00s)
[00:11:34] <jepler> since I know at address 0x1000 is where GPIOs start, according to 7i80hdman.pdf

[00:30:14] <skunkworks_> seb_kuzminsky: what ever rtai that is on the wheezy livecd.
[00:30:28] <skunkworks_> when I get a chance I will test the your new kernel
[00:30:34] <skunkworks_> old kernel - or whatever ;)
[00:31:02] <skunkworks_> it is a GA-j1800-mumblemumble
[00:31:07] <cradek> skunkworks_: had you previously run 3.4.55 on it successfully?
[00:35:22] -!- lyzidiamond has quit [Remote host closed the connection]
[00:38:26] -!- lyzidiamond has quit [Read error: Connection reset by peer]
[00:39:14] <PCW> actually should be
[00:39:16] <PCW> 83 c2 00 10 00 00 00 00 01 00 00 00 00 00 00 00
[00:39:54] <jepler> I probably transcribed it wrong, it's not cut and pasted

[00:44:14] <jepler> I'm trying to read the "alt source reg"
[00:44:24] <jepler> 83 42 00 12
[00:44:28] <jepler> it reads back all ffs
[00:44:31] <PCW> not readable
[00:44:34] <jepler> oh
[00:44:37] <jepler> OK
[00:44:40] <PCW> the ddr register is though
[00:45:28] <PCW> @ 0x110X
[00:45:29] -!- micges-dev1 [micges-dev1!~x@esx124.neoplus.adsl.tpnet.pl] has joined #linuxcnc-devel
[00:46:06] <PCW> and theres always the cookie at 0x0100
[00:46:43] <jepler> I can read that
[00:48:44] -!- micges-dev has quit [Ping timeout: 240 seconds]
[00:52:02] <PCW> so 83 42 0011
[00:52:04] <PCW> will read all three DDR registers (which should be 24 bits of right aligned 0s and startup or wd bite)
[00:52:34] -!- lyzidiam_ has quit [Remote host closed the connection]
[00:52:49] <PCW> (well 3 32 bit words each with 24 bits of 0's)

[00:54:02] <CaptHindsight> where is the new 3.4.87 rtai kernel posted?
[00:55:24] <cradek> the new one is a rebuilt 3.4.55
[00:56:09] <cradek> the older 87 with known problems is at www.linuxcnc.org wheezy base

[01:00:29] <jepler> somehow the I/O pins are numbered wrong
[01:00:41] prtksxna is now known as zz_prtksxna
[01:01:00] <jepler> 024.is_output / invert_output and 000.out all affect the same LED
[01:01:12] <jepler> 024.out doesn't seem to affect anything

[01:11:27] <jepler> looks like linuxcnc is transmitting the wrong packet
[01:13:27] <jepler> (that's with gpio 001 and 025.out set to true according to hal)
[01:13:35] <seb_kuzminsky> CaptHindsight: get version 3.4.55-0linuxcnc from here:

[01:13:56] <seb_kuzminsky> (typing this via wifi from the machine that crashed with 3.4.87 and 3.4.96)
[01:14:07] <seb_kuzminsky> so: so far so good, let's see what skunkworks says
[01:14:24] <CaptHindsight> I was just looking at that repo, thanks
[01:15:15] <cradek> oh it fixes yours too - yay

[01:42:44] <skunkworks_> jepler: nice!
[01:54:34] <dgarr> i think the reason apt-get install --reinstall mishaps were caused because i had multiple lines that could find rtai-modules-3.4-9-rtai-686-pae
[01:58:05] <dgarr> apt-cache policy rtai-modules-3.4-9-rtai-686-pae shows two places for 3.9.260.g6394e67:

[02:00:35] <dgarr> i got linux-headers from debs and built linuxcnc 2.6 without errors but it will not run, at insmod rtai_hal machine becomes unresponsive

[02:11:12] <cradek> I don't think I see anything you did wrong... what a weird hang.
[02:14:31] <dgarr> i just repeated insmod ../rtai_hal.ko, it didn't hang right way, top wouldn't start; rmmod rtai_hal, top works -- it is weird
[02:14:54] <cradek> no oopses in dmesg?
[02:19:04] -!- sumpfralle1 has quit [Quit: Leaving.]
[02:20:21] <dgarr> nil no clues in dmesg
[02:20:33] <seb_kuzminsky> dgarr: did you make clean? it might not notice the new kernel headers right?
[02:20:46] <dgarr> yes clean
[02:24:11] <seb_kuzminsky> well shit
[02:25:19] <cradek> (new live image boots and runs in qemu, rtai latency test works)
[02:25:34] <seb_kuzminsky> with 3.4.55-0linuxcnc?
[02:26:11] <cradek> I think it's called 3.4.55-1linuxcnc
[02:26:54] <seb_kuzminsky> that one's no good, i goofed the kernel config

[02:27:18] <cradek> that's what apt gave me when I pointed to your highlab repo
[02:27:19] <seb_kuzminsky> let me build a -2linuxcnc nice and fresh, hold on a few hours
[02:27:26] <seb_kuzminsky> yes...
[02:27:29] * seb_kuzminsky hides in shame
[02:27:34] <cradek> haha
[02:27:37] <cradek> this is getting silly
[02:27:42] <dgarr> latest test: hang didn't occur with: realtime start returned (no hang), but now realtime stop seems to hang trying to rmmod rtai_sched
[02:27:58] <seb_kuzminsky> that's crazy
[02:28:03] <seb_kuzminsky> how does memtest86 run on that machine?
[02:28:38] <cradek> does memtest86 use pae? that's another very big difference between these and the lucid kernel
[02:29:30] <dgarr> i don't know , will try and report back, I ran this machine yesterday (cutting) for more than 8 hours using vmlinuz-2.6.32-122-rtai
[02:29:31] <seb_kuzminsky> i have a non-pae kernel too, but i haven't been testing it
[02:29:46] <seb_kuzminsky> ok, that's a pretty good indication that the hardware is sound...

[07:23:45] <seb_kuzminsky> ok, a clean set of linux/rtai debs is up in the usual place:
[07:24:16] <seb_kuzminsky> deb
http://highlab.com/~seb/linuxcnc/rtai-debs (wheezy|precise) main
[07:24:25] prtksxna is now known as zz_prtksxna
[07:24:27] <seb_kuzminsky> the linux-image version is 3.4.55-2linuxcnc
[07:25:02] <h_maximilian> Good morning Seb
[07:25:25] <h_maximilian> are you in a European tz or are you up late ?
[07:25:31] zz_prtksxna is now known as prtksxna
[07:25:39] <seb_kuzminsky> the rtai-modules version is unfortunately still 3.9.260.gsomething
[07:25:50] <h_maximilian> I did not continue last night with my gantry setup, will do so now.
[07:26:09] <seb_kuzminsky> i've run these debs on a wheezy vm (success) and on a precise baremetal machine (success, was flaky with 3.4.87 and .96)
[07:26:44] <seb_kuzminsky> these are my release candidates, please take them for a whirl and let me know if there's anything amiss
[07:27:00] <h_maximilian> Question: I noticed that the rtai kernel is compiled without magic sysrq support. Is that by design, or does nobody else need it ? Or does it hurt the rt.
[07:27:17] <seb_kuzminsky> hi h_maximilian! i'm in MDT (UTC-6)
[07:27:52] <h_maximilian> I am in CET
[07:28:06] <h_maximilian> so you are either up earlier or up very late ;)
[07:28:31] <seb_kuzminsky> h_maximilian: you must be using an older rtai kernel, the one i just build has sysrq:
[07:28:35] <seb_kuzminsky> CONFIG_MAGIC_SYSRQ=y
[07:30:27] <h_maximilian> ah, great, thanks. I found that magic sysrq quite helpfull whenever something went wrong.
[07:30:38] <seb_kuzminsky> yeah it's handy
[07:30:49] <seb_kuzminsky> good luck with your gantry, i'm about to go to bed :-)

[10:44:57] <h_maximilian> Hi
[10:46:06] <h_maximilian> whenever I have G61 or G61.1 in my ngc file the gantry just makes a big jump on the two x axes and hits a following error. No problem if I use G64.
[10:46:22] <h_maximilian> like g64p0
[10:46:39] <h_maximilian> does anybody have an idea what could cause this ?

[16:21:34] -!- dgarr has quit [Ping timeout: 264 seconds]
[16:22:07] <seb_kuzminsky> there is probably some usb device on-board that is not accepting its address and complaining in the dmesg

[16:26:06] <seb_kuzminsky> ah
[16:26:18] <seb_kuzminsky> are you using an external 8-port usb hub?
[16:26:40] <cradek> I think the thing that doesn't accept its address is the "hub" which is all the onboard ports
[16:26:59] <skunkworks> what is the wheezy version of rmmod?
[16:27:03] <seb_kuzminsky> [ 53.748730] hub 3-0:1.0: unable to enumerate USB device on port 1
[16:27:27] <seb_kuzminsky> i think the hub is talking but the thing plugged in to the hub is not talking
[16:27:38] * seb_kuzminsky <--- guessing
[16:27:49] <skunkworks> ok - sudo rmmod worked.. (but didn't make the usb work..)
[16:28:09] <seb_kuzminsky> skunkworks: wheezy's rmmod is from kmod 9
[16:28:40] <seb_kuzminsky> can you pastebin a dmesg of a usb insertion after the rmmod
[16:28:43] <seb_kuzminsky> ?

[16:29:27] <cradek> that's excellent
[16:29:36] <cradek> we all want that!
[16:29:51] <skunkworks> seb_kuzminsky, I will try again - but I don't think anything happens in dmesg with pugging/unplugging a usb device
[16:30:05] <seb_kuzminsky> skunkworks: hm, weird
[16:30:14] <seb_kuzminsky> awallin: sweet :-)
[16:30:49] <seb_kuzminsky> skunkworks: also, 'lsusb -t' shows a tree view of your usb busses, which would be helpful in figuring out where in the chain the problem is
[16:31:06] <awallin> I'm probably going to need some help interfacing with the linuxcnc interpreter at some point - I have an old hack by mpictor working I think, but it's quite ugly
[16:32:09] <seb_kuzminsky> awallin: feel free to ask here or on the emc-developers list any time
[16:33:20] <awallin> seb_kuzminsky: ok, I will :) It'll take a moment to get this new scheme going at the "hello world" level first..

[18:04:28] <cradek> gconftool-2 (a utility to write an entry in an overly-complicated config file tree in some unnecessary-bs xml format) fails because $DISPLAY is not set so it can't launch a dbus-daemon, whatever that is

[18:05:35] <cradek> [rtfm...] oh maybe --direct will work
[18:05:56] <cradek> skunkworks: yep
[18:06:31] <cradek> skunkworks: wow look at all the choices you have
[18:06:43] <skunkworks> I think I have fiddled with all of them...
[18:12:59] <seb_kuzminsky> except the one pcw_home fiddled with
[18:17:14] <skunkworks> what?
[18:17:26] <skunkworks> oh
[18:17:28] <skunkworks> :)
[18:17:37] <skunkworks> what is 2.6.32?
[18:18:42] <pcw_home> whatever the livecd RTAI kernel version is

[18:39:59] <jepler> pcw_home: repeating myself one last time, I found and fixed a 64-bit hm2-eth bug. now it works.
[18:40:42] <micges-dev> seb_kuzminsky: haha
[18:41:45] <pcw_home> Great (and glad its not some other weird machine specific oddness)
[18:43:41] <pcw_home> I ran uspace-hm2-eth over the weekend at 2KHz on the J1800-DH2 and had no issues
[18:44:31] <jepler> nice
[18:44:39] <jepler> I think skunkworks has had something running for days too
[18:45:58] <pcw_home> I only stopped it to try the 7I80-16 GPIO
[18:46:22] <jepler> I'd have saved an hour of debugging if I'd believed I hadn't transcribed that first network transaction wrong
[18:46:32] <skunkworks> I just took it down the morning - so a few days. (at 1khz)
[18:46:37] <cradek> aha, I got update-notifier to work
[18:46:38] <jepler> since the bug was simply causing 4 zero bytes to be spuriously inserted
[18:46:49] <pcw_home> so it was busted (too many bytes)
[18:47:04] <cradek> now I just need to turn off the "Notify me of a new Ubuntu [sic] version:" thing
[18:47:12] <jepler> right, so that's how gpio.000.out turned on the led for gpio 24
[18:49:03] -!- Lathe_newbie has quit [Ping timeout: 240 seconds]
[18:50:18] <pcw_home> the packet parser believes any kind of crap you throw at it until the first detected error
[18:50:19] <pcw_home> maybe the writes should increment a write success counter to verify that write succeeded
[18:51:47] <jepler> those last 4 bytes would be interpreted as the start of a new command, right?
[18:52:01] <jepler> I'd have to read the docs to see how 00 00 would be interpreted in the protocol
[18:52:27] <pcw_home> Yeah but 0 is not a valid command so it should have caused a parse error (and red light)

[18:53:07] <jepler> there may well have been an error light I didn't look at or understand
[18:54:01] <pcw_home> I can try by hand, if it doesn't raise a parser error it certainly should
[18:56:33] asheppard is now known as sheppard

[19:05:18] <pcw_home> but:
[19:05:19] <pcw_home> >83c20411ffffffffffffffffffffffff000001420001
[19:05:21] <pcw_home> No answer
[19:05:22] <pcw_home> and red fault light illuminates
[19:06:33] <jepler> so also too bad I didn't go looking at the LEDs
[19:08:17] <Tom_itx> damn. had been having network issues with 10.04. had tried the live cd, SSD and regular HDD with no luck
[19:08:30] <Tom_itx> loaded the live cd again today and it connected right away
[19:08:37] <cradek> turning off "Notify me of a new Ubuntu [sic] version" does not stick, but who knows if it does anything, anyway

[19:26:37] <seb_kuzminsky> skunkworks: if you update you'll get 3.4.55-3linuxcnc, i changed some usb config setting, maybe it helps your machine?
[19:29:58] <cradek> ooh look, updates are available
[19:31:01] <seb_kuzminsky> cradek: and it's not even a downgrade this time
[19:31:15] <cradek> yay
[19:31:24] <cradek> you're good as long as you don't run out of positive integers
[19:32:29] <cradek> "restart required" because of the kernel update, even though it was our kernel

[20:19:06] <skunkworks_> seb_kuzminsky: ok - won't be able to test until tomorrow
[20:24:10] <seb_kuzminsky> skunkworks_: no problem
[20:27:57] <seb_kuzminsky> cradek 3.4.55-3linuxcnc is the exact same linux & rtai code as -2linuxcnc, but with a couple of extra config options enabled
[20:28:06] <cradek> cool
[20:28:25] <cradek> oh my, zsync is awesome
[20:28:25] <seb_kuzminsky> i dont have any high hopes that it'll fix skunkworks_ 's problem, it's a shot in the dark :-(
[20:28:33] * seb_kuzminsky google zsync
[20:28:39] <cradek> it synced the new iso, downloading only 93 MB
[20:28:44] <cradek> how is that even possible
[20:29:27] <seb_kuzminsky> wow, that's cool
[20:29:38] <cradek> it knows all about gzip
[20:29:45] <cradek> it must know about a lot of things to pull that off
[20:30:01] <seb_kuzminsky> "client-side rsync" violates my understanding of rsync
[20:31:30] <cradek> I put the zsync file on wlo - try it if you have an old iso

[21:07:59] <seb_kuzminsky> zsync some from cradek
[21:09:33] <skunkworks_> hmm - does that work?

[21:16:28] <skunkworks_> which makes more sense to me..
[21:17:04] <seb_kuzminsky> skunkworks_: i see from your "working lsusb" that you have two hubs plugged in, and i see from the rtai kernel dmesg that it's complaining about an overcurrent condition
[21:17:19] <seb_kuzminsky> can you try just one device plugged directly into the computer, with no hubs or anything else to draw current?
[21:17:27] <seb_kuzminsky> (just trying to triangulate the problem)
[21:18:10] <cradek> seb_kuzminsky: I think that is not really an overcurrent error. jepler looked at the source and concluded the internets are wrong about that.
[21:19:00] <skunkworks_> seb_kuzminsky: I can test some more... (although - if I don't have anything usb plugged in - I still get the -110 errors)
[21:19:08] <seb_kuzminsky> this error is in error? [ 1.214627] ehci_hcd 0000:00:1d.0: USB 2.0 started, EHCI 1.00, overcurrent ignored
[21:19:51] <cradek> "overcurrent ignored" is the result of a module option we added to try to fix the error -110, which we mistakenly thought was an overcurrent detection
[21:19:54] <seb_kuzminsky> skunkworks_: oh, hm, maybe i'm barking up the wrong tree then
[21:20:23] <cradek> ... because I used the internets carelessly to determine that -110 meant overcurrent, which it doesn't really
[21:22:10] <skunkworks_> I love cooking with red palm oil.. it is like axle greese
