| wpwrak | kristianpaul: you mean this guy ? http://www.epiq-solutions.com/product_detail.php?line=Bitshark&product=Bitshark%20USRP | 04:28 |
|---|---|---|
| wpwrak | kristianpaul: no need to get half the USRP again, when i already have one ;-) | 04:29 |
| wpwrak | kristianpaul: alas, only RX, not TX, | 04:29 |
| wpwrak | i like the frequency range, though | 04:30 |
| wpwrak | kristianpaul: (mm) why, anything interesting happening there today ? | 04:31 |
| wpwrak | kristianpaul: (HDPE) reusable as in ... all it takes is a trip to the supermarket and you'll have supply for free ? (grocery bags) | 04:32 |
| wpwrak | kristianpaul: i think plastified wax may be an interesting option to look into. that may work with low pressure while still having many benefits of plastics - ideal for prototyping. | 04:33 |
| wpwrak | kristianpaul: i already did a try (in a old wooden counterweight mold) with pure stearine. that stuff is as liquid as water and stays liquid for a very long time (minutes). unfortunately, it adheres better to the wood than to itself, so the parts breaks up already when opening the mold. still, with a bit of plastic added, this could get interesting. | 04:39 |
| wpwrak | kristianpaul: (there are many wax+plastic procedures and recipes under the name of "machineable wax") | 04:41 |

| kristianpaul | wpwrak: (milymist) not not today but somedays happen :) | 07:42 |
| kristianpaul | wpwrak: (epiq) i pointed tou you because frequency range | 07:43 |
| wpwrak | kristianpaul: (mm) ah, i think the news propagate also here when something fun happens. most of the daily fpga stuff would be a bit obscure for me anyway :) | 07:44 |
| wpwrak | kristianpaul: (epiq) yeah, the frequency range is nice. ettus should steal some ideas and make an xwbx ;-) (extra-wide) | 07:45 |
| kristianpaul | wpwrak: (mm) for mee too, but i still learning , i heard you we're interested in a Ben based on milkymsit SoC | 07:45 |
| wpwrak | (mm-based ben) i think it would be a good platform for disseminating the mm. make it something people can relate to. not just yet another black box with cables coming out. | 07:49 |
| wpwrak | so i'm thinking of it more in terms of PR and attracting developers than in terms of something immediately useful | 07:50 |
| wpwrak | i think that MM holds quite some promise for the future, thought. the project just mustn't run out of steam :) | 07:51 |
| kristianpaul | sure MM One VJ Stuff is lekernel focus and MM SoC is for any want use it | 07:58 |
| kristianpaul | plus lm32 is beeing used for other things right now | 07:59 |
| kristianpaul | > | 08:01 |
| kristianpaul | > What is your LM32 SoC doing by the way? | 08:01 |
| kristianpaul | Mobile telephony layer 1 processing mostly. | 08:01 |
| kristianpaul | oh | 08:01 |
| kristianpaul | from mm list if you are not there | 08:01 |
| wpwrak | L1 already sounds better :) | 08:06 |

| rafa | wpwrak is the only one working at qi??! :) | 13:36 |
| kristianpaul | rafa: no | 13:41 |
| kristianpaul | :) | 13:41 |
| kristianpaul | just one are lazy than others :P | 13:41 |
| kristianpaul | but IRC is so quite this days... | 13:43 |
| kristianpaul | wonder way | 13:43 |
| rafa | or maybe several guys do not use git and qi-bot is not so smart enough to realize their work ;) | 13:43 |
| kristianpaul | s/way/why | 13:43 |
| wpwrak | retiring for lunch ans siesta soon. the hay fever is bad today :-( wish those plants would get their mating rituals over with ... | 13:44 |
| kristianpaul | rafa: i dont use git yet | 13:44 |
| kristianpaul | but i'll do soon | 13:44 |
| kristianpaul | i started with github :) | 13:44 |
| rafa | wpwrak: have a good rest | 13:44 |
| kristianpaul | next qi git next my own git at home :) | 13:44 |
| kristianpaul | rafa: do you ise git or CVS o anithing?? btw | 13:45 |
| rafa | kristianpaul: svn.. at home | 13:45 |
| kristianpaul | i see | 13:45 |
| rafa | kristianpaul: maybe git if I do something with kernel linux | 13:45 |
| kristianpaul | git is cool i realized that now i want it at home :) | 13:46 |
| kristianpaul | and a simple web interface that do not require apache and/or php | 13:46 |
| kristianpaul | :) | 13:46 |
| rafa | kristianpaul: ..well.. svn is nice as well.. and I do not use a lot of features or complex situations to learn a lot more git :) | 13:46 |
| rafa | web interface? .. for what? | 13:46 |
| kristianpaul | to see my comming history | 13:50 |
| kristianpaul | changes | 13:50 |
| kristianpaul | easilly ! | 13:50 |
| rafa | git log ? git diff ? | 13:51 |
| kristianpaul | ahh | 13:51 |
| kristianpaul | hehe | 13:51 |
| kristianpaul | you know git more that me for sure :) | 13:51 |
| Ayla | hi there | 15:02 |
| Ayla | larsc: hi there too | 15:02 |
| Ayla | I have a question, regarding the RTC driver | 15:02 |
| Ayla | the RTC device is not initialized with the "wakeup" flag, | 15:03 |
| Ayla | is that an omit, or maybe it's not working yet? | 15:03 |
| larsc | Ayla: it's just not implemented. but should be easy to do | 15:16 |
| larsc | Ayla: do you want to try to add support for it? | 15:18 |
| Ayla | larsc: okay, but AFAIK, the functions are already there, that's why i'm asking | 15:18 |
| Ayla | I could try, but I'm a kernel newbie | 15:18 |
| larsc | it's really easy | 15:18 |
| larsc | take a look how the other rtc drivers do it | 15:19 |
| larsc | it's basically adding suspend and resume callbacks and then call irq_wake_enable, irq_wake_disable there | 15:19 |
| Ayla | yes, in theory it's simple | 15:22 |
| Ayla | but I'm browsing the code since 6pm | 15:22 |
| Ayla | :) | 15:22 |
| Ayla | I did add a call to device_init_wakeup() on jz4740_rtc_probe() right before the "return 0" | 15:25 |
| Ayla | it should mark the wakeup as available, and so create the "wakealarm" file on /sys/class/rtc | 15:26 |
| larsc | yes | 15:30 |
| larsc | and then in the suspend callback you need to check whether it is set to tru | 15:31 |
| larsc | e | 15:31 |
| larsc | and if it is call enable_irq_wake on the rtc irq | 15:31 |
| Ayla | oups | 15:39 |
| Ayla | got disconnected... | 15:39 |
| Ayla | hmm, if I compare the two rtc_class_ops between davinci and jz4740, jz4740 misses irq_set_freq and irq_set_state callbacks | 15:44 |
| Ayla | meh, the wakealarm file is not created even when calling "device_init_wakeup" !( | 15:50 |
| Ayla | :( | 15:50 |
| larsc | where did you add the device_init_wakeup? | 16:06 |
| Ayla | rtc-jz4740.c, line 286 | 16:07 |
| larsc | you need to call it before calling rtc_device_register | 16:08 |
| Ayla | no, I doubt it | 16:08 |
| Ayla | look at rtc-sh.c or rtc-davinci.c | 16:09 |
| larsc | well. if you look at rtc_device_register you'll see that it only creates the device if device_init_wakeup has already been called | 16:09 |
| Ayla | then, I don't understand why it's done after on the other files :s | 16:10 |
| Ayla | whohouu! the wakealarm file is here | 16:16 |
| Ayla | larsc: about the check in the suspend callback, isn't it already done in an upper level? | 16:20 |
| Ayla | in the global part of the RTC driver | 16:20 |
| larsc | Ayla: i don't think so | 16:26 |
| tuxbrain2 | Ayla: for even a more newbee in this matters than you... that means that NN should be able to be used as alarm clock?? that would be awesome and also a good motivation to push the suspend/resume instead of full shutdown | 16:26 |
| tuxbrain2 | with the power volume NN has can wake up even diazepamed marmot :) | 16:28 |
| Ayla | tuxbrain2: no | 16:28 |
| Ayla | :) | 16:29 |
| tuxbrain2 | ouch | 16:29 |
| Ayla | well, it could be set as an alarm clock | 16:29 |
| Ayla | but that's not my goal | 16:29 |
| tuxbrain2 | what is your objective then? | 16:30 |
| Ayla | suspend to RAM | 16:30 |
| tuxbrain2 | :) I like it too :) | 16:30 |
| tuxbrain2 | and indeed is the first steep to be able to transform the NN in such alarm clock :), I'm couriouse to know how much standby time can hold NN suspended :) | 16:32 |
| tuxbrain2 | count with tester here :) | 16:33 |
| Ayla | well, calculate it | 16:33 |
| Ayla | the RTC chip should be less than 50mW IMHO | 16:34 |
| wpwrak | RAM refresh will also have a cost | 16:34 |
| tuxbrain2 | nothing like real world "in situ" testing :) | 16:35 |
| Ayla | larsc, what do you call the "suspend callback" ? | 16:35 |
| Ayla | wpwrak: overall, the power cost would be very low | 16:35 |
| tuxbrain2 | wpwrak: any stimation on power consumption of this refresh? | 16:36 |
| kristianpaul | Ayla: suspend to ram is a linux feature? | 16:37 |
| kristianpaul | or how are you achive that? | 16:38 |
| kristianpaul | i will kike tu see an hibertante feature | 16:38 |
| Ayla | kristianpaul, yes, it's handled by the kernel | 16:38 |
| wpwrak | tuxbrain2: hmm, self refresh current of the RAM chip is 6 mA | 16:40 |
| Ayla | the battery is 3,3V? | 16:41 |
| wpwrak | Ayla: the RAM is on the 3.3 V regulator | 16:42 |
| tuxbrain2 | Ayla: 3,7V | 16:42 |
| tuxbrain2 | what's the equivalence of 50mW to mA? | 16:43 |
| Ayla | A*V = W | 16:43 |
| Ayla | so 6mA * 3,3V = 20mW | 16:44 |
| tuxbrain2 | so 50mW=15,15mA | 16:44 |
| Ayla | does anybody know how much power the nanonote/dingoo eat on standard use? | 16:44 |
| Ayla | the RAM eats 6mA with its standard clock, I guess | 16:46 |
| Ayla | on suspend, it may be clocked way slower | 16:46 |
| tuxbrain2 | if only Ram+RTC powered on NN should stay suspended for 40h aprox... not bad | 16:47 |
| wpwrak | Ayla: that's the self refresh current without clock. http://downloads.qi-hardware.com/hardware/sakc/datasheet/U3~P3V56S40ETP-G6~32MB.pdf | 16:47 |
| wpwrak | Ayla: page 6, last item in the table | 16:47 |
| Ayla | thanks | 16:47 |
| Ayla | how much power does the NN suck in normal use? | 16:48 |
| bartbes | it doesn't suck ;) | 16:48 |
| wpwrak | Ayla: btw, here's the real treasure chest: http://en.qi-hardware.com/wiki/Inventory | 16:48 |
| tuxbrain2 | barbes:it lick slowly a delicately each mA | 16:49 |
| Ayla | wpwrak: oh, thank you ;) | 16:51 |
| bartbes | you're missing a t there, tuxbrain2 | 16:51 |
| Ayla | I'd be very useful if I had a nanonote ;) | 16:51 |
| wpwrak | Ayla: http://lists.en.qi-hardware.com/pipermail/discussion/2010-May/004414.html | 16:51 |
| rafa | wpwrak: list.. we should use the cpu for all, as it costs 0 :) | 16:51 |
| wpwrak | rafa: and have lots of leds :) | 16:52 |
| bartbes | and don't ever buy fpgas again | 16:54 |
| bartbes | those are by far the most expensive things on the list | 16:54 |
| tuxbrain2 | Ayla: from a mail on early ages (06/11/2009) from Bas : | 16:55 |
| tuxbrain2 | Hi, | 16:55 |
| tuxbrain2 | I have measured the power consumption of the device, by removing the | 16:55 |
| tuxbrain2 | battery and tapping the usb cable, insering a current and voltage meter | 16:56 |
| tuxbrain2 | in it. I found the following: | 16:56 |
| tuxbrain2 | - When the device is on, with the display enabled, it uses 123 mA. | 16:56 |
| tuxbrain2 | - When the device is on, with the display disabled, it uses 37 mA. | 16:56 |
| tuxbrain2 | - When the device is off, it uses 4.5 mA. | 16:56 |
| tuxbrain2 | The device used 4.7 V during the measurement. The battery that came | 16:56 |
| tuxbrain2 | with it says 4.2 V, 850 mAh. | 16:56 |
| tuxbrain2 | This leads to the following times: | 16:56 |
| tuxbrain2 | - on with display: 6.2 hours. | 16:56 |
| tuxbrain2 | - on without display: 20.5 hours. | 16:56 |
| tuxbrain2 | - off: 7.0 days. | 16:56 |
| Ayla | 37mA? That's really low | 16:56 |
| Ayla | larsc: okay, I wrote the suspend/resume routines :) | 16:57 |
| Ayla | it's time for a test | 16:57 |
| wpwrak | with USB connected, you burn 330 mA at 3.3 V = 1 mW on R34. (usb detection) | 16:58 |
| Action: wpwrak remembers the suspend/resume wars at openmoko :) | 16:58 | |
| Ayla | you mean 1W ? | 16:59 |
| wpwrak | err, sorry. 330 uA ;-) | 16:59 |
| Ayla | ah :) | 16:59 |
| wpwrak | you would notice 1 W when it melts through the plastic ;-) | 17:00 |
| kristianpaul | resume ! | 17:00 |
| Last message repeated 1 time(s). | 17:00 | |
| kristianpaul | suspend is not usefull ;) | 17:00 |
| Ayla | suspend is working good | 17:00 |
| Ayla | at least on dingoo | 17:00 |
| tuxbrain2 | kristianpaul: hahahahaah | 17:00 |
| kristianpaul | tuxbrain2: :) | 17:00 |
| Ayla | the only problem is that we can't resume ;) | 17:00 |
| kristianpaul | i know :( | 17:00 |
| kristianpaul | suspen is okay for non monolic kernels i always hadissues with linux | 17:01 |
| kristianpaul | thats why mobile phones can suspend | 17:01 |
| kristianpaul | hehe | 17:01 |
| Action: kristianpaul runs before got blamed | 17:01 | |
| kristianpaul | s/got/get | 17:01 |
| tuxbrain2 | wpwrak: old times when all were fixed with a capacitor :) | 17:02 |
| kristianpaul | tuxbrain2: man thats arelly oold times let me said :) | 17:02 |
| Action: kristianpaul miss standalone apps | 17:02 | |
| bartbes | so when would you use suspend/resume? | 17:02 |
| kristianpaul | whatever works well :) | 17:03 |
| kristianpaul | or help tuxbrain2 wakeup early :) | 17:03 |
| tuxbrain2 | yep :) | 17:03 |
| tuxbrain2 | or avoid arrive late to pick up his daughter at school due a too long siesta | 17:04 |
| kristianpaul | hehe | 17:04 |
| tuxbrain2 | only happens once but my wife doesn't forget ... never | 17:04 |
| rafa | that happens once but she will remember often | 17:07 |
| tuxbrain2 | rafa: yes :) that the senctence | 17:08 |
| tuxbrain2 | that's the sentence | 17:08 |
| Ayla | okay, I did set up an alarm in 3 minutes | 17:11 |
| Ayla | :D | 17:11 |
| Ayla | let's see what happens | 17:11 |
| Ayla | meh... :( | 17:16 |
| Ayla | it does not seem to work | 17:16 |
| tuxbrain2 | oooohhhh | 17:17 |
| wpwrak | tuxbrain2: (old times) yeah, thinking of it, almost every gta02 hardware problem was connected to a capacitor in one way or another ;-) | 17:19 |
| Ayla | larsc, mth: http://pastebin.com/RqP2RuND | 17:28 |
| Ayla | here are my changes | 17:28 |
| Ayla | unfortunately, it still refuses to wake up | 17:29 |
| larsc | have you tested whether the alarm fires if the device is not asleep? | 17:30 |
| Ayla | I'm doing it right now | 17:31 |
| Ayla | (compiling) | 17:31 |
| tuxbrain2 | ok guy time to sleep for me, Ayla I wish you the best of lucks in your resarch good k8 | 17:45 |
| Ayla | thanks | 17:46 |
| Ayla | larsc: I added a printk in the interrupt | 17:53 |
| Ayla | when the alarm timer went out, it did set the "alarm_pending" flag from "no" to "yes" in /proc/driver/rtc | 17:53 |
| Ayla | but my printk didn't appear on dmesg | 17:53 |
| Ayla | and as that handler should clear the "alarm_pending" flag, I suppose that the interrupt is masked somewhere... | 17:56 |
| Ayla | meh | 17:59 |
| Ayla | include/linux/interrupt.h: | 17:59 |
| Ayla | "IRQF_NO_SUSPEND - Do not disable this IRQ during suspend" | 17:59 |
| Ayla | I'll add that flag to the request_irq call | 18:01 |
| Ayla | crap | 18:12 |
| Ayla | it's only for 2.6.36 xD | 18:12 |
| rafa | larsc: are you working with rc 2.6.36 right?.. As you know we try to add latest version.. are you happy with your current kernel version? | 18:27 |
| wpwrak | rafa: btw, would you know anyone around here who may have a RF lab that i could use for free for testing my wireless board, particularly the antenna ? e.g., at a university or such ? | 19:44 |
| wpwrak | rafa: desirable lab features would be a spectrum analyzer that covers the 2-3 GHz band and a reasonably large anechoic chamber (>= 1.5m) | 19:45 |
| wpwrak | rafa: "would you know" = including via recursion :) | 19:47 |
| wpwrak | rafa: "around here" = ideally, in town. but then, i don't mind driving a bit. | 19:49 |
| wpwrak | rafa: (desirable lab features) spectrum analyzer with tracking generator or separate rf generator (also 2-3 GHz band) | 19:55 |
| wpwrak | rafa: of course, the wider the frequency range, the merrier ;-) | 19:55 |
| wpwrak | rafa: measurements would be: 1) antenna tuning, 2) calibration of my USRP2 and my antennas (that way, i can do more things with my own equipment), and 3) check for unwanted emissions | 19:59 |
| rafa | wpwrak: i know people from UBA, UNS and UNcoma.. if some of those universities has I will let you know.. let me ask | 20:08 |
| wpwrak | rafa: kewl, thanks ! they may in turn also know someone, etc. | 20:09 |
| rafa | wpwrak: yeah | 20:53 |
| kristianpaul | plop | 21:45 |
