2010-12-16 05:59 <adamwang> wolfspraul, everytime I need to generate shopping list I must 'make clean'?
2010-12-16 06:22 <adamwang> hmm...it must. I got my answer.

2010-12-16 13:27 <kyak> agreed
2010-12-16 13:30 <qnrq> hi, I just received my nanonote today and I just hooked it up to the net. when I run opkg update it tries to connect to a file that returns 404, more specifically http://downloads.qi-hardware.com/software/packages/openwrt/xburst/latest/Packages.gz is it just temporarily down or is there a new location that was exluded from my release? did ofc google :-)
2010-12-16 13:53 <wpwrak> qnrq: i think the whole package database is very out of sync. it's at ttp://downloads.qi-hardware.com/software/packages/NanoNote/Ben/latest/
2010-12-16 13:53 <wpwrak> but from april ..
2010-12-16 13:53 <qnrq> wpwrak: yeah, heh.. is there any way to change the download dest the same way as one would edit /etc/apt/sources.lst?
2010-12-16 13:54 <wpwrak> probably ;) but i never tried to find where this lives. you may have to poke around /etc for a bit
2010-12-16 13:55 <qnrq> that's what I thought, I set up a temporary mirror and edited /etc/hosts for now :)
2010-12-16 13:55 <wpwrak> and i'm not sure if the packages will actually be useful. i think there were one or two libc changes in between.
2010-12-16 13:55 <qnrq> I'm just trying to play around with the sound for now anyway

2010-12-16 16:00 <kristianpaul> wpwrak: qi-bot may be is fault of apache indexer
2010-12-16 16:01 <kristianpaul> page indexer soemthing, as i know all stuff from download.qi-.. is not listed as it is on the directory
2010-12-16 16:09 <wpwrak> kristianpaul: hmm ? which problem are you referring to ? "not listed as it is on the directory" = how does it differ ?
2010-12-16 16:10 <kristianpaul> "not listed as it is on the directory"
2010-12-16 16:11 <kristianpaul> or well i think that may be a cause
2010-12-16 16:11 <wpwrak> cause for what ?
2010-12-16 16:11 <wpwrak> you speak in riddles ;-)
2010-12-16 16:12 <kristianpaul> hmm let me check i'm following tha backlog right
2010-12-16 20:08 <wolfspraul> qnrq_: maybe xiangfu can help you
2010-12-16 20:09 <wolfspraul> xiangfu: if you read the irclogs, you see that qnrq had some problem with the OpenWrt packages URL
2010-12-16 20:10 <FrankBlues> waves
2010-12-16 20:11 <xiangfu> qnrq_: /etc/opkg.conf :)
2010-12-16 20:11 <wolfspraul> waves back but doesn't know how to do so in a proper IRC way... :-)
2010-12-16 20:12 <FrankBlues> "/me does action"
2010-12-16 20:12 <FrankBlues> Thanks wolfspraul!
2010-12-16 20:13 <wolfspraul> thanks FrankBlues
2010-12-16 20:13 <wolfspraul> yeah, it works!
2010-12-16 20:14 <wolfspraul> now it only needs to sink into my brain...
2010-12-16 20:14 <wolfspraul> is happy, just got up getting my coffee!
2010-12-16 20:14 <wpwrak> ;-)
2010-12-16 20:19 <qi-bot> [commit] Xiangfu Liu: bash-files: update the package url http://qi-hw.com/p/openwrt-xburst/6f74fce
2010-12-16 20:20 <wolfspraul> the first task my coffee has to help me over: setting up a new server, using the shiny GNU parted instead of old fashioned fdisk. but then... mklabel MSDOS!
2010-12-16 20:21 <wolfspraul> yes, it's true. it reminds me. the partition sector format most of us are using is still horrible old MSDOS style, with endless broken special cases. argh.
2010-12-16 20:21 <kristianpaul> yup :(
2010-12-16 20:21 <wolfspraul> truth hurts...
2010-12-16 20:21 <kristianpaul> At least there is openbsd users around? :)
2010-12-16 20:21 <wolfspraul> what is the general replacement these days? or is there none because partitions are 'bad' anyway?
2010-12-16 20:22 <wolfspraul> I guess I still go with msdos
2010-12-16 20:22 <kristianpaul> dont know really
2010-12-16 20:22 <wolfspraul> mac has long switched to gpt
2010-12-16 20:22 <wpwrak> good old dos partition table seems to work fine :-) never had any troubles
2010-12-16 20:23 <kristianpaul> Btw is that fedora, what are you setting up?
2010-12-16 20:23 <kristianpaul> already got FEL and really curios of tring more in depth
2010-12-16 20:24 <wolfspraul> wpwrak: good that you don't (seem to) know how it counts cylinders, heads, etc. and how much magic is needed to translate it to modern disks without rounding problems etc.
2010-12-16 20:24 <wolfspraul> kristianpaul: yes, and in such opportunities I always try to improve several things at once, to not waste too much time.
2010-12-16 20:25 <wolfspraul> so I will also improve the backups substantially, use LVM snapshots, prepare for an actual rescue/recovery scenario on another server, etc.
2010-12-16 20:25 <kristianpaul> good :)
2010-12-16 20:25 <wolfspraul> so far I'm just running rsync, but without actually ever walking through a rescue scenario
2010-12-16 20:25 <wolfspraul> so that's a mess
2010-12-16 20:25 <kristianpaul> snaphots are very usefull
2010-12-16 20:25 <wolfspraul> rsync from underneath running mysql databases and such...
2010-12-16 20:25 <wolfspraul> don't even think about it
2010-12-16 20:25 <wolfspraul> :-)
2010-12-16 20:26 <kristianpaul> sure dont (*sigh*)
2010-12-16 20:26 <kristianpaul> i wonder if that worked (considering the running thing)
2010-12-16 20:26 <kristianpaul> i guess it did :)
2010-12-16 20:27 <wpwrak> wolfspraul: oh, i know very well what ugly things it does ;-)) remember lilo ? in "linear mode", it translates things to that CHS format
2010-12-16 20:27 <wpwrak> wolfspraul: but recently, i never ran into any troubles with that stuff
2010-12-16 20:28 <wolfspraul> yes true, seems it is successfully 'masked'
2010-12-16 20:28 <wpwrak> wolfspraul: (of course, having handed off lilo maintenance many years ago may help :) so, end-user's perspective here
2010-12-16 20:28 <wolfspraul> but still there, and the name is a reminder...
2010-12-16 20:31 <kristianpaul> ah wikireader content is package in some binary way
2010-12-16 21:04 <qnrq_> wolfspraul, xiangfu: thanks a lot for the the help with /etc/opkg.conf :-)
2010-12-16 21:06 <xiangfu> qnrq_: we try to build the new packages whis weekend. hope we don't get much errors :) , if all goes fine. we will have a update packages.
2010-12-16 21:07 <qnrq_> xiangfu: awesome! I just got my chance to start playing around with my nanonote today :)
2010-12-16 21:08 <wolfspraul> qnrq_: thanks for buying one!
2010-12-16 21:09 <qnrq_> wolfspraul: not sure if I'm the one to thank here, so far it's a beautiful device to hack :>
2010-12-16 21:11 <wolfspraul> ok keep us posted...
2010-12-16 21:13 <qnrq_> for sure :)
2010-12-16 21:21 <kristianpaul> wpwrak: (DMA) is just for mmc as far as read on qi wiki
2010-12-16 21:29 <kristianpaul> well at least in nanonote
2010-12-16 21:36 <wpwrak> kristianpaul: yeah, it seems that there's no external DMA. there's only an empty chapter in the 4720 data sheet about it, that's all.
2010-12-16 21:38 <kristianpaul> argg (empty)
2010-12-16 21:46 <kristianpaul> wpwrak: ddi you look at page 107 from  jz4740_pm ?
2010-12-16 21:46 <kristianpaul> s/ddi/did
2010-12-16 21:53 <kristianpaul> :-)
2010-12-16 21:54 <wpwrak> well yes, that page and the ones following it ;-)
2010-12-16 21:54 <kristianpaul> i dont undestand :/
2010-12-16 21:55 <kristianpaul> that pages, well i still readin what DMA is ;-)
2010-12-16 21:55 <wpwrak> the description is a bit cryptic. they also jump between register-based and descriptor-based operation
2010-12-16 21:56 <kristianpaul> hmm, Is like a bulk transfer in USB?
2010-12-16 21:56 <wpwrak> hmm, kinda. basically, instead of setting up one transfer, you define a list of transfers
2010-12-16 21:56 <kristianpaul> ah
2010-12-16 21:57 <kristianpaul> i need that ;)
2010-12-16 21:57 <kristianpaul> can i set up 2048? (theorically)
2010-12-16 21:57 <wpwrak> not sure if it helps you much. you still need a trigger. and there are no simple external DMA triggers.
2010-12-16 21:57 <wpwrak> 2048 what ?
2010-12-16 21:58 <kristianpaul> transfers of 8 bits each
2010-12-16 21:59 <wpwrak> probably, yes
2010-12-16 21:59 <wpwrak> but again, how do you trigger it ? it's messy
2010-12-16 21:59 <kristianpaul> :/
2010-12-16 22:01 <adamwang> wolfspraul, i think next time we need re-layout for Jtag/serial cable
2010-12-16 22:01 <wolfspraul> what did you find?
2010-12-16 22:01 <adamwang> for JTAG 14pins receptacle i found http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&WT.z_homepage_link=hp_go_button&KeyWords=79109-1006&x=0&y=0
2010-12-16 22:02 <wolfspraul> adamwang: ahh. have a story for you there. wpwrak thinks it's super easy to source a 14-pin jtag + 4-pin serial connector set that will have the same height
2010-12-16 22:02 <adamwang> click the datasheet link,
2010-12-16 22:02 <wpwrak> it is :) just don't mix product lines ;-)
2010-12-16 22:03 <adamwang> let me finish first
2010-12-16 22:03 <wpwrak> hey, how hard can it be if even the arduino crowd does it ? ;-))
2010-12-16 22:03 <wolfspraul> wow that is crazy expensive
2010-12-16 22:03 <wolfspraul> 3.18 USD
2010-12-16 22:03 <wolfspraul> should be more like 10 cents :-)
2010-12-16 22:04 <adamwang> no matter you selected a 3M part or I found Molex, the receptacle parts always has 'positioner' to hook up pcb,
2010-12-16 22:05 <adamwang> current pcb gerber there's no two 'through holes' can be inserted!
2010-12-16 22:05 <wpwrak> adamwang: would going through-hole be an option ?
2010-12-16 22:05 <wolfspraul> too late, gerber already out
2010-12-16 22:05 <wolfspraul> but in the future, sure
2010-12-16 22:05 <wolfspraul> adamwang: at least for 100 the price is 1.87 USD. still crazy expensive
2010-12-16 22:06 <wpwrak>  yeah, i meant in the future
2010-12-16 22:06 <wpwrak> wolfspraul: even this connector needs new holes for the positioning pins
2010-12-16 22:07 <wpwrak> ah wait, no
2010-12-16 22:07 <wolfspraul> adamwang: maybe you can ask Yanjun Luo where he sourced the connectors and we buy from there?
2010-12-16 22:07 <wolfspraul> that's another option...
2010-12-16 22:07 <wolfspraul> but if this Molex one works just buy that, is faster probably
2010-12-16 22:07 <wpwrak> naw, yes, it need holes
2010-12-16 22:08 <wpwrak> got confused because the data sheet first shows one without
2010-12-16 22:08 <adamwang> they are matched each other, so i want directly buy this.
2010-12-16 22:09 <adamwang> if you go to see the bom to find p/n: 87832-1420 , then you can find 79109-1006 matched in Digi-Key.
2010-12-16 22:10 <adamwang> well...so this means when the parts arrives, I need to manually cut those two positioners. man!
2010-12-16 22:10 <adamwang> and probably loose accurate placement!
2010-12-16 22:11 <adamwang> well, i think i still can control this.
2010-12-16 22:12 <adamwang> umm..i'll ask him..but if no datasheet from him available...then i order Molex this one.
2010-12-16 22:13 <wolfspraul> the digikey p/n of the new one is WM18702-ND
2010-12-16 22:13 <wolfspraul> should I update the bom?
2010-12-16 22:13 <adamwang> not now
2010-12-16 22:13 <adamwang> wait..
2010-12-16 22:14 <wpwrak> adamwang: are you sure about the positioners ?
2010-12-16 22:14 <wpwrak> adamwang: the ~-1006 doesn't seem to have them
2010-12-16 22:14 <wolfspraul> adamwang: the old one was http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=3M5414CT-ND
2010-12-16 22:14 <wolfspraul> what was wrong with that?
2010-12-16 22:15 <adamwang> sure! why not? the datasheet needs positioners, even without this, trying to imagine how this SMD part will be mouted accurately on board.
2010-12-16 22:15 <adamwang> go to page 4
2010-12-16 22:15 <adamwang> you will see
2010-12-16 22:17 <wpwrak> adamwang: yes, page 4 had those pegs. but this is for the parts listed on page 5. the ~1006 is on pages 1/2
2010-12-16 22:17 <adamwang> 1.45mm height
2010-12-16 22:18 <adamwang> see page 4, there's recommended PCB layout
2010-12-16 22:18 <wpwrak> adamwang: yes, that's for the parts listed on page 5 :)
2010-12-16 22:19 <adamwang> there's two circles in there(means through holes needed)
2010-12-16 22:19 <wpwrak> adamwang: do you want the 79109-1006 ? or another one ?
2010-12-16 22:19 <wpwrak> look at page 2. it explicitly says "WITHOUT PEG OPTION"
2010-12-16 22:21 <wolfspraul> the 3M one has no 'locator posts'
2010-12-16 22:21 <wolfspraul> it's an option but with p/n -2000- it doesn't have them
2010-12-16 22:21 <adamwang> wait..let me see page 2
2010-12-16 22:22 <wolfspraul> (and for 7 positions it's not available, only 8 or more if I understand correctly)
2010-12-16 22:23 <adamwang> wpwrak, you are right! the p/n: 79109-1006 without peg positioner
2010-12-16 22:24 <adamwang> but this is still very bad...
2010-12-16 22:24 <wolfspraul> adamwang: what is wrong with 3M 153214-2000-RB-WB ?
2010-12-16 22:24 <adamwang> means smt machine needs to pick & place in 'correct' location.
2010-12-16 22:25 <wpwrak> adamwang: yup
2010-12-16 22:26 <wpwrak> adamwang: if the machine doesn't have a positioning error > 0.1 mm, you're probably fine. if the connector needs a little extra push, nobody will notice :)
2010-12-16 22:26 <adamwang> the terminal won't be contact well to 87831-1420 pin header even they are the same 2.00mm pitch
2010-12-16 22:26 <adamwang> wpwrak, hahaha..
2010-12-16 22:27 <adamwang> i don't like this way..
2010-12-16 22:27 <adamwang> anyway...just fyi and records this to be fixed next time.
2010-12-16 22:28 <adamwang> but bad thing is now the thickness is 1.6mm, also there's routed trace on both side..
2010-12-16 22:28 <wpwrak> with positioning pegs/pins/posts/nipples it's nicer, agreed
2010-12-16 22:29 <adamwang> surely , that's the rules for matching mechanical parts!
2010-12-16 22:29 <wpwrak> why is 1.6 mm (PCB thickness ?) a problem ?
2010-12-16 22:30 <wolfspraul> still don't know what's wrong with the 3M part
2010-12-16 22:30 <adamwang> wait
2010-12-16 22:31 <wpwrak> adamwang: i've been fighting all day long today with such positioning posts ;-) in my mill, the board moves a little (sideways) when the tool pushes against it. so holes that i mill (instead of drilling) end up a little too small. great fun ...
2010-12-16 22:33 <adamwang> hmm...well...always careful the peg/positioner/pins while design stage...then safe later
2010-12-16 22:34 <wpwrak> for my DIY board i usually just cut them off. too much work to drill those holes :)
2010-12-16 22:34 <wpwrak> boardS
2010-12-16 22:35 <adamwang> ha...well but you know if those go to smt/dip process during MP production, it saves time without your diy! :)
2010-12-16 22:36 <adamwang> of course now you must diy.
2010-12-16 22:36 <adamwang> and hates those holes to hell.
2010-12-16 22:36 <adamwang> wolfspraul, the 3M first needs peg/positioner
2010-12-16 22:37 <wolfspraul> what do you mean with needs?
2010-12-16 22:37 <adamwang> then when you select matched parts, also check inlet of Mate point .
2010-12-16 22:37 <wolfspraul> it does not have what they call 'locator posts'
2010-12-16 22:38 <wolfspraul> the 3M part number we have does not have positioner, I think
2010-12-16 22:38 <wpwrak> adamwang: in the last days, i improved my collection of programs for milling boards and such. now i can actually precision-drill things. so the pegs no longer scare me :) (well, just a little - still need to add a compensation for the board deflection)
2010-12-16 22:39 <adamwang> no , it has. see the recommended solder pad layout, there're two.
2010-12-16 22:39 <adamwang> wpwrak, wow..man! incredible you are!
2010-12-16 22:39 <adamwang> well...i have to work others...cu
2010-12-16 22:41 <wpwrak> ;-))
2010-12-16 22:41 <wpwrak> wolfspraul: what's the problem with the 3M part ? it sounds as if you're looking for an exact replacement ?
2010-12-16 22:42 <wolfspraul> no I don't care which one is best
2010-12-16 22:42 <wolfspraul> but the 3M part we have has no positioners
2010-12-16 22:43 <wolfspraul> adamwang: I don't see it. note 4 says it's optional, and in the ordering information if the p/n is -2000- it has no positioner.
2010-12-16 22:44 <wolfspraul> if it's -2020- then it has the positioner, but according to the datasheet that option is only available for 8 positions or more (see Note 4)
2010-12-16 22:44 <wpwrak> adamwang: look carefully - the connector exists with and without pegs. they just didn't show the footprint without them
2010-12-16 22:45 <wpwrak> adamwang: (see "Ordering Information"). the equivalent part with pegs would be 153214-2020-RB-WB
2010-12-16 22:45 <adamwang> ha...wait
2010-12-16 22:45 <wolfspraul> wpwrak: yes but positioner is only available for 8 or more positions, if I understand correctly
2010-12-16 22:46 <wolfspraul> but not sure about that it says "optional locator posts available for positions 8 and greater"
2010-12-16 22:46 <adamwang> hm..you both are right
2010-12-16 22:46 <wpwrak> .. which mdigi-key have as 153214-2020-RB
2010-12-16 22:46 <wpwrak> wolfspraul: 14 > 8 :-)
2010-12-16 22:47 <wolfspraul> ok makes sense so they count each pin
2010-12-16 22:47 <wpwrak> yup
2010-12-16 22:48 <wolfspraul> well then, we can have 14 with or without pegs, and the current p/n we had was without
2010-12-16 22:48 <wolfspraul> same as the Molex part only that the Molex one is more expensive
2010-12-16 22:48 <adamwang> wait..guys..i'm drawing ...i am not only to see this part only
2010-12-16 22:49 <adamwang> later you will see..i haven't decide to buy which one exactly
2010-12-16 22:49 <wolfspraul> ok sure
2010-12-16 22:49 <adamwang> just a second
2010-12-16 22:49 <wolfspraul> all fine
2010-12-16 23:12 <adamwang> wolfspraul, http://downloads.qi-hardware.com/people/adam/m1/jtagserial/finding_a_correct_height_for_P1.png
2010-12-16 23:14 <adamwang> my goal is try to find p1 with correct height and 14pins receptacle with good 'contact point'.
2010-12-16 23:14 <wolfspraul> ok looks good
2010-12-16 23:15 <adamwang> the '?' is the P1 on Jtag/serial board....so let us see carefully with datasheet!
2010-12-16 23:16 <adamwang> hope we won't make mistakes again. :)
2010-12-16 23:18 <adamwang> i'll find a suitable height for P1, be careful keep the J6 and receptacle with good 'contact point' enough!
2010-12-16 23:18 <adamwang> see you later
2010-12-16 23:37 <kristianpaul> nice see adamwang more often at irc :)
