| adamwang | wolfspraul, everytime I need to generate shopping list I must 'make clean'? | 05:59 |
| adamwang | hmm...it must. I got my answer. | 06:22 |
| kristianpaul | [6~[6~[6~[6~[6~[6~/n | 13:21 |
| kyak | agreed | 13:27 |
| 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 :-) | 13:30 |
| 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/ | 13:53 |
| wpwrak | but from april .. | 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? | 13:53 |
| wpwrak | probably ;) but i never tried to find where this lives. you may have to poke around /etc for a bit | 13:54 |
| qnrq | that's what I thought, I set up a temporary mirror and edited /etc/hosts for now :) | 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. | 13:55 |
| qnrq | I'm just trying to play around with the sound for now anyway | 13:55 |

| qi-bot | [commit] Werner Almesberger: atusb: updated and improved CAM script http://qi-hw.com/p/ben-wpan/ba310a8 | 14:38 |
| kristianpaul | wpwrak: qi-bot may be is fault of apache indexer | 16:00 |
| kristianpaul | page indexer soemthing, as i know all stuff from download.qi-.. is not listed as it is on the directory | 16:01 |
| wpwrak | kristianpaul: hmm ? which problem are you referring to ? "not listed as it is on the directory" = how does it differ ? | 16:09 |
| kristianpaul | "not listed as it is on the directory" | 16:10 |
| kristianpaul | or well i think that may be a cause | 16:11 |
| wpwrak | cause for what ? | 16:11 |
| wpwrak | you speak in riddles ;-) | 16:11 |
| kristianpaul | hmm let me check i'm following tha backlog right | 16:12 |
| wolfspraul | qnrq_: maybe xiangfu can help you | 20:08 |
| wolfspraul | xiangfu: if you read the irclogs, you see that qnrq had some problem with the OpenWrt packages URL | 20:09 |
| Action: FrankBlues waves | 20:10 | |
| xiangfu | qnrq_: /etc/opkg.conf :) | 20:11 |
| wolfspraul | waves back but doesn't know how to do so in a proper IRC way... :-) | 20:11 |
| FrankBlues | "/me does action" | 20:12 |
| FrankBlues | Thanks wolfspraul! | 20:12 |
| Action: wolfspraul thanks FrankBlues | 20:13 | |
| wolfspraul | yeah, it works! | 20:13 |
| wolfspraul | now it only needs to sink into my brain... | 20:14 |
| Action: wolfspraul is happy, just got up getting my coffee! | 20:14 | |
| wpwrak | ;-) | 20:14 |
| qi-bot | [commit] Xiangfu Liu: bash-files: update the package url http://qi-hw.com/p/openwrt-xburst/6f74fce | 20:19 |
| 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! | 20:20 |
| 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. | 20:21 |
| kristianpaul | yup :( | 20:21 |
| wolfspraul | truth hurts... | 20:21 |
| kristianpaul | At least there is openbsd users around? :) | 20:21 |
| wolfspraul | what is the general replacement these days? or is there none because partitions are 'bad' anyway? | 20:21 |
| wolfspraul | I guess I still go with msdos | 20:22 |
| kristianpaul | dont know really | 20:22 |
| wolfspraul | mac has long switched to gpt | 20:22 |
| wpwrak | good old dos partition table seems to work fine :-) never had any troubles | 20:22 |
| kristianpaul | Btw is that fedora, what are you setting up? | 20:23 |
| Action: kristianpaul already got FEL and really curios of tring more in depth | 20:23 | |
| 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. | 20:24 |
| wolfspraul | kristianpaul: yes, and in such opportunities I always try to improve several things at once, to not waste too much time. | 20:24 |
| wolfspraul | so I will also improve the backups substantially, use LVM snapshots, prepare for an actual rescue/recovery scenario on another server, etc. | 20:25 |
| kristianpaul | good :) | 20:25 |
| wolfspraul | so far I'm just running rsync, but without actually ever walking through a rescue scenario | 20:25 |
| wolfspraul | so that's a mess | 20:25 |
| kristianpaul | snaphots are very usefull | 20:25 |
| wolfspraul | rsync from underneath running mysql databases and such... | 20:25 |
| wolfspraul | don't even think about it | 20:25 |
| wolfspraul | :-) | 20:25 |
| kristianpaul | sure dont (*sigh*) | 20:26 |
| kristianpaul | i wonder if that worked (considering the running thing) | 20:26 |
| kristianpaul | i guess it did :) | 20:26 |
| wpwrak | wolfspraul: oh, i know very well what ugly things it does ;-)) remember lilo ? in "linear mode", it translates things to that CHS format | 20:27 |
| wpwrak | wolfspraul: but recently, i never ran into any troubles with that stuff | 20:27 |
| wolfspraul | yes true, seems it is successfully 'masked' | 20:28 |
| wpwrak | wolfspraul: (of course, having handed off lilo maintenance many years ago may help :) so, end-user's perspective here | 20:28 |
| wolfspraul | but still there, and the name is a reminder... | 20:28 |
| kristianpaul | ah wikireader content is package in some binary way | 20:31 |
| qnrq_ | wolfspraul, xiangfu: thanks a lot for the the help with /etc/opkg.conf :-) | 21:04 |
| 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. | 21:06 |
| qnrq_ | xiangfu: awesome! I just got my chance to start playing around with my nanonote today :) | 21:07 |
| wolfspraul | qnrq_: thanks for buying one! | 21:08 |
| qnrq_ | wolfspraul: not sure if I'm the one to thank here, so far it's a beautiful device to hack :> | 21:09 |
| wolfspraul | ok keep us posted... | 21:11 |
| qnrq_ | for sure :) | 21:13 |
| kristianpaul | wpwrak: (DMA) is just for mmc as far as read on qi wiki | 21:21 |
| kristianpaul | well at least in nanonote | 21:29 |
| 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. | 21:36 |
| kristianpaul | argg (empty) | 21:38 |
| kristianpaul | wpwrak: ddi you look at page 107 from jz4740_pm ? | 21:46 |
| kristianpaul | s/ddi/did | 21:46 |
| kristianpaul | :-) | 21:53 |
| wpwrak | well yes, that page and the ones following it ;-) | 21:54 |
| kristianpaul | i dont undestand :/ | 21:54 |
| kristianpaul | that pages, well i still readin what DMA is ;-) | 21:55 |
| wpwrak | the description is a bit cryptic. they also jump between register-based and descriptor-based operation | 21:55 |
| kristianpaul | hmm, Is like a bulk transfer in USB? | 21:56 |
| wpwrak | hmm, kinda. basically, instead of setting up one transfer, you define a list of transfers | 21:56 |
| kristianpaul | ah | 21:56 |
| kristianpaul | i need that ;) | 21:57 |
| kristianpaul | can i set up 2048? (theorically) | 21:57 |
| wpwrak | not sure if it helps you much. you still need a trigger. and there are no simple external DMA triggers. | 21:57 |
| wpwrak | 2048 what ? | 21:57 |
| kristianpaul | transfers of 8 bits each | 21:58 |
| wpwrak | probably, yes | 21:59 |
| wpwrak | but again, how do you trigger it ? it's messy | 21:59 |
| kristianpaul | :/ | 21:59 |
| adamwang | wolfspraul, i think next time we need re-layout for Jtag/serial cable | 22:01 |
| wolfspraul | what did you find? | 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 | 22:01 |
| 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 | 22:02 |
| adamwang | click the datasheet link, | 22:02 |
| wpwrak | it is :) just don't mix product lines ;-) | 22:02 |
| adamwang | let me finish first | 22:03 |
| wpwrak | hey, how hard can it be if even the arduino crowd does it ? ;-)) | 22:03 |
| wolfspraul | wow that is crazy expensive | 22:03 |
| wolfspraul | 3.18 USD | 22:03 |
| wolfspraul | should be more like 10 cents :-) | 22:03 |
| adamwang | no matter you selected a 3M part or I found Molex, the receptacle parts always has 'positioner' to hook up pcb, | 22:04 |
| adamwang | current pcb gerber there's no two 'through holes' can be inserted! | 22:05 |
| wpwrak | adamwang: would going through-hole be an option ? | 22:05 |
| wolfspraul | too late, gerber already out | 22:05 |
| wolfspraul | but in the future, sure | 22:05 |
| wolfspraul | adamwang: at least for 100 the price is 1.87 USD. still crazy expensive | 22:05 |
| wpwrak | yeah, i meant in the future | 22:06 |
| wpwrak | wolfspraul: even this connector needs new holes for the positioning pins | 22:06 |
| wpwrak | ah wait, no | 22:07 |
| wolfspraul | adamwang: maybe you can ask Yanjun Luo where he sourced the connectors and we buy from there? | 22:07 |
| wolfspraul | that's another option... | 22:07 |
| wolfspraul | but if this Molex one works just buy that, is faster probably | 22:07 |
| wpwrak | naw, yes, it need holes | 22:07 |
| wpwrak | got confused because the data sheet first shows one without | 22:08 |
| adamwang | they are matched each other, so i want directly buy this. | 22:08 |
| adamwang | if you go to see the bom to find p/n: 87832-1420 , then you can find 79109-1006 matched in Digi-Key. | 22:09 |
| adamwang | well...so this means when the parts arrives, I need to manually cut those two positioners. man! | 22:10 |
| adamwang | and probably loose accurate placement! | 22:10 |
| adamwang | well, i think i still can control this. | 22:11 |
| adamwang | umm..i'll ask him..but if no datasheet from him available...then i order Molex this one. | 22:12 |
| wolfspraul | the digikey p/n of the new one is WM18702-ND | 22:13 |
| wolfspraul | should I update the bom? | 22:13 |
| adamwang | not now | 22:13 |
| adamwang | wait.. | 22:13 |
| wpwrak | adamwang: are you sure about the positioners ? | 22:14 |
| wpwrak | adamwang: the ~-1006 doesn't seem to have them | 22:14 |
| wolfspraul | adamwang: the old one was http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=3M5414CT-ND | 22:14 |
| wolfspraul | what was wrong with that? | 22:14 |
| adamwang | sure! why not? the datasheet needs positioners, even without this, trying to imagine how this SMD part will be mouted accurately on board. | 22:15 |
| adamwang | go to page 4 | 22:15 |
| adamwang | you will see | 22:15 |
| 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 | 22:17 |
| adamwang | 1.45mm height | 22:17 |
| adamwang | see page 4, there's recommended PCB layout | 22:18 |
| wpwrak | adamwang: yes, that's for the parts listed on page 5 :) | 22:18 |
| adamwang | there's two circles in there(means through holes needed) | 22:19 |
| wpwrak | adamwang: do you want the 79109-1006 ? or another one ? | 22:19 |
| wpwrak | look at page 2. it explicitly says "WITHOUT PEG OPTION" | 22:19 |
| wolfspraul | the 3M one has no 'locator posts' | 22:21 |
| wolfspraul | it's an option but with p/n -2000- it doesn't have them | 22:21 |
| adamwang | wait..let me see page 2 | 22:21 |
| wolfspraul | (and for 7 positions it's not available, only 8 or more if I understand correctly) | 22:22 |
| adamwang | wpwrak, you are right! the p/n: 79109-1006 without peg positioner | 22:23 |
| adamwang | but this is still very bad... | 22:24 |
| wolfspraul | adamwang: what is wrong with 3M 153214-2000-RB-WB ? | 22:24 |
| adamwang | means smt machine needs to pick & place in 'correct' location. | 22:24 |
| wpwrak | adamwang: yup | 22:25 |
| 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 :) | 22:26 |
| adamwang | the terminal won't be contact well to 87831-1420 pin header even they are the same 2.00mm pitch | 22:26 |
| adamwang | wpwrak, hahaha.. | 22:26 |
| adamwang | i don't like this way.. | 22:27 |
| adamwang | anyway...just fyi and records this to be fixed next time. | 22:27 |
| adamwang | but bad thing is now the thickness is 1.6mm, also there's routed trace on both side.. | 22:28 |
| wpwrak | with positioning pegs/pins/posts/nipples it's nicer, agreed | 22:28 |
| adamwang | surely , that's the rules for matching mechanical parts! | 22:29 |
| wpwrak | why is 1.6 mm (PCB thickness ?) a problem ? | 22:29 |
| wolfspraul | still don't know what's wrong with the 3M part | 22:30 |
| adamwang | wait | 22:30 |
| 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 ... | 22:31 |
| adamwang | hmm...well...always careful the peg/positioner/pins while design stage...then safe later | 22:33 |
| wpwrak | for my DIY board i usually just cut them off. too much work to drill those holes :) | 22:34 |
| wpwrak | boardS | 22:34 |
| adamwang | ha...well but you know if those go to smt/dip process during MP production, it saves time without your diy! :) | 22:35 |
| adamwang | of course now you must diy. | 22:36 |
| adamwang | and hates those holes to hell. | 22:36 |
| adamwang | wolfspraul, the 3M first needs peg/positioner | 22:36 |
| wolfspraul | what do you mean with needs? | 22:37 |
| adamwang | then when you select matched parts, also check inlet of Mate point . | 22:37 |
| wolfspraul | it does not have what they call 'locator posts' | 22:37 |
| wolfspraul | the 3M part number we have does not have positioner, I think | 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) | 22:38 |
| adamwang | no , it has. see the recommended solder pad layout, there're two. | 22:39 |
| adamwang | wpwrak, wow..man! incredible you are! | 22:39 |
| adamwang | well...i have to work others...cu | 22:39 |
| wpwrak | ;-)) | 22:41 |
| wpwrak | wolfspraul: what's the problem with the 3M part ? it sounds as if you're looking for an exact replacement ? | 22:41 |
| wolfspraul | no I don't care which one is best | 22:42 |
| wolfspraul | but the 3M part we have has no positioners | 22:42 |
| 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. | 22:43 |
| 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) | 22:44 |
| wpwrak | adamwang: look carefully - the connector exists with and without pegs. they just didn't show the footprint without them | 22:44 |
| wpwrak | adamwang: (see "Ordering Information"). the equivalent part with pegs would be 153214-2020-RB-WB | 22:45 |
| adamwang | ha...wait | 22:45 |
| wolfspraul | wpwrak: yes but positioner is only available for 8 or more positions, if I understand correctly | 22:45 |
| wolfspraul | but not sure about that it says "optional locator posts available for positions 8 and greater" | 22:46 |
| adamwang | hm..you both are right | 22:46 |
| wpwrak | .. which mdigi-key have as 153214-2020-RB | 22:46 |
| wpwrak | wolfspraul: 14 > 8 :-) | 22:46 |
| wolfspraul | ok makes sense so they count each pin | 22:47 |
| wpwrak | yup | 22:47 |
| wolfspraul | well then, we can have 14 with or without pegs, and the current p/n we had was without | 22:48 |
| wolfspraul | same as the Molex part only that the Molex one is more expensive | 22:48 |
| adamwang | wait..guys..i'm drawing ...i am not only to see this part only | 22:48 |
| adamwang | later you will see..i haven't decide to buy which one exactly | 22:49 |
| wolfspraul | ok sure | 22:49 |
| adamwang | just a second | 22:49 |
| wolfspraul | all fine | 22:49 |
| adamwang | wolfspraul, http://downloads.qi-hardware.com/people/adam/m1/jtagserial/finding_a_correct_height_for_P1.png | 23:12 |
| adamwang | my goal is try to find p1 with correct height and 14pins receptacle with good 'contact point'. | 23:14 |
| wolfspraul | ok looks good | 23:14 |
| adamwang | the '?' is the P1 on Jtag/serial board....so let us see carefully with datasheet! | 23:15 |
| adamwang | hope we won't make mistakes again. :) | 23:16 |
| adamwang | i'll find a suitable height for P1, be careful keep the J6 and receptacle with good 'contact point' enough! | 23:18 |
| adamwang | see you later | 23:18 |
| kristianpaul | nice see adamwang more often at irc :) | 23:37 |
| kristianpaul | see and read :) | 23:37 |
| wpwrak | yup :) | 23:39 |
| kristianpaul | he finally got the SYNC/4 | 23:41 |
| kristianpaul | now lets if if sinthetize ;-) | 23:41 |
| kristianpaul | i need read this doc from xilinx about xst, i wonder what lekernel_ had to deal when making MM SoC ;) | 23:42 |
| kristianpaul | good ir pass :) | 23:45 |
| kristianpaul | DDR3 in Xue is to much challeging? | 23:50 |
| kristianpaul | is not to* | 23:50 |
