| wpwrak | how long does the RTC actually maintain time ? | 03:34 |
|---|---|---|
| kristianpaul | nothing | 03:48 |
| kristianpaul | well, seconds i guess | 03:48 |
| wpwrak | there's a circuit that's supposed to power it for a bit: D1 and C20 (47 uF). but i'm not sure this does much good. | 03:51 |
| kristianpaul | bit? like the first palm m100 ;) | 03:52 |
| wpwrak | hmm, the diode has a reverse current of about 2 uA | 03:55 |
| wpwrak | hmm, simulation says that this should be sufficient for about 4 seconds | 04:01 |
| wpwrak | kristianpaul: your estimate wasn't so bad :) | 04:02 |
| wpwrak | actually, it's worse. since the diode drops some 200-300 mV. that's just about the voltage range the cap could buffer over. so it's ~1 second, worst-case. | 04:21 |
| wpwrak | maybe in real life this translates to up to 10 s. perhaps that's what causes the ben to lock up if you do a very quick power cycle. | 04:22 |
| rjeffries | has this been discussed? has the right license it woudl appear. nice design http://teholabs.com/docs/procyon:overview | 04:41 |

| wolfspraul | kristianpaul: you are too fast! [spam] :-) | 11:25 |
| wolfspraul | thanks for helping | 11:25 |
| kristianpaul | hehe :-), just getting ready to go work :) | 11:27 |
| kristianpaul | btw is taking so long the package with stickers/brochure to arrive | 11:37 |
| kristianpaul | but i guess no rush, a package from Artyom took near 3 months to get here.. | 11:38 |
| wolfspraul | who knows | 11:38 |
| kristianpaul | indeed | 11:38 |
| kristianpaul | must go, read you later | 11:39 |
| wolfspraul | in the last 2.5 years that I've sent hundreds of packages I think I can remember loosing one, and that was to Colombia | 11:39 |
| kristianpaul | :-| | 11:39 |
| wolfspraul | Mirko dropped a letter (unregistered, untrackable) into the mail but it never arrived | 11:39 |
| wolfspraul | that was the only case ever | 11:39 |
| wolfspraul | so let's see | 11:39 |
| wolfspraul | maybe it arrives, maybe not | 11:39 |
| wolfspraul | if not, then we need to send another one... | 11:39 |
| kristianpaul | lets wait | 11:40 |
| kristianpaul | will be the first package i fail to receiver, hope not | 11:40 |
| antoniodariush | wpwrak, hi, if "dmesg | grep at86rf230" does not return anything in the nanonote, does this mean that the kernel is not configured for the atben? | 14:37 |
| blogic | "lsmod | grep at" ? | 14:39 |
| antoniodariush | blogic, nothing | 14:40 |
| blogic | then i would assume that the image lacks atben support | 14:40 |
| antoniodariush | even though I have these http://pastebin.com/5TnB5Fkk | 14:44 |
| antoniodariush | ? | 14:44 |
| blogic | hmmmm | 14:44 |
| blogic | not sure | 14:44 |
| wpwrak | maybe the module isn't loaded ? | 14:46 |
| antoniodariush | what u mean by loaded | 14:47 |
| wpwrak | and you also need CONFIG_IEEE802154_DRIVERS, CONFIG_SPI_BITBANG, CONFIG_SPI_GPIO | 14:49 |
| blogic | antoniodariush: find /lib/modules/ | grep at | 14:49 |
| blogic | are they even installed int he rfs ? | 14:50 |
| wpwrak | heh :) | 14:50 |
| wpwrak | and if they exist, lsmod will show is they're being used | 14:50 |
| jivs | I get this /lib/modules/3.0.0/at86rf230.ko | 14:59 |
| jivs | /lib/modules/3.0.0/spi_atben.ko | 14:59 |
| jivs | for the find command above | 14:59 |
| jivs | but nothing for lsmod |grep at | 15:00 |
| blogic | there will be some missing package then | 15:00 |
| blogic | causing those packets to not be installed | 15:01 |
| blogic | causing those packets to not be inserted | 15:01 |
| jivs | okay i will try to reflash by adding more packages as wpwrak suggested.. | 15:02 |
| blogic | xiangfu: is this the latest http://patchwork.openwrt.org/patch/1439/ ? | 15:02 |
| blogic | ah he is not online | 15:02 |
| blogic | does xiangfu have access to target/linux/xburst in the owrt repo ? | 15:03 |
| blogic | it seems weird that i need to merge this for him | 15:03 |
| jivs | wpwrak, is IEEE802154_DRIVERS same as PACKAGE_kmod-ieee802154 . I don't see any package with ieee on its name in my toolchain | 15:06 |
| wpwrak | jivs: i don't know how those packages translate to kernel config options. but there is also a CONFIG_IEEE802154, so chances are that CONFIG_IEEE802154_DRIVERS and PACKAGE_kmod-ieee802154 are not the same | 15:34 |
| blogic | wpwrak: i asusme he uses this http://phrozen.org/wpan.mk | 15:35 |
| blogic | i gave that link to xiangfu and i assume he integrated it to the qi tree | 15:35 |
| jivs | okay | 15:36 |
| wpwrak | this looks like a typo: CONFIG_IEEE802154_DRIVER vs. CONFIG_IEEE802154_DRIVERS | 15:36 |
| blogic | indeed | 15:37 |
| wpwrak | also, no =y needed for CONFIG_MAC802154 ? | 15:37 |
| Action: blogic looks | 15:37 | |
| blogic | nope | 15:38 |
| blogic | that is correct | 15:38 |
| blogic | the CONFIG_IEEE802154_DRIVER=y vs CONFIG_IEEE802154_DRIVERS=y looks like the candidate for the borkage | 15:39 |
| blogic | (missing S at the end) | 15:39 |
| blogic | jivs: i am almost certain this is the case | 15:45 |
| blogic | the dependency chain of at86rf230 is broken without that symbol | 15:45 |
| blogic | jivs: did you build the image yourself ? | 15:45 |
| jivs | yes blogic | 15:45 |
| antoniodariush | so i guess we need to wait for xiangfu ? | 15:46 |
| jivs | how can we fix this on our image? if we can | 15:46 |
| blogic | you need to rebuild the image | 15:46 |
| blogic | vi package/kernel/module/wpan.mk | 15:46 |
| jivs | ok | 15:46 |
| blogic | go to the line that has CONFIG_IEEE802154_DRIVER=y \ and add a S before the =y | 15:46 |
| blogic | then do | 15:46 |
| blogic | rm -r tmp/ && make menuconfig (save and exit to update the config | 15:47 |
| jow_laptop | (make defconfig) | 15:47 |
| blogic | make package/kernel/clean && make V=99 | 15:47 |
| blogic | :D | 15:47 |
| blogic | jow_laptop: ok | 15:47 |
| blogic | rm -r tmp/ && make defconfig && make package/kernel/clean && make V=99 | 15:47 |
| blogic | that will build an image with the fix applied | 15:47 |
| blogic | before flashing it you can see if the file is now included | 15:48 |
| blogic | you can do so by calling | 15:48 |
| blogic | ls build_dir/target-mips_r2_uClibc-0.9.32/root-xburst/lib/modules/ | 15:49 |
| jivs | thank u blogic and jow_laptop , i am building new image now | 15:49 |
| blogic | the path might be slightly different to build_dir/target-mips_r2_uClibc-0.9.32/root-xburst/lib/modules/ | 15:49 |
| blogic | is the nanonote mips or mipsel ? | 15:49 |
| jow_laptop | mipsel | 15:50 |
| jivs | mipsel | 15:50 |
| blogic | ok | 15:51 |
| blogic | it will be build_dir/target-mipsel_r2_uClibc-0.9.32/root-xburst/lib/modules/... in that case | 15:52 |
| blogic | there will only be one folder of the format target-mipsel_r2_uClibc-0.9.32 so just use ls to check please | 15:52 |
| Action: blogic might continue to integrate 802.15.4 in owrt tonight | 15:52 | |
| jivs | okay | 15:53 |
| jivs | the folder now had these files af_802154.ko crc-ccitt.ko fakelb.ko mac802154.ko spidev.ko | 15:54 |
| jivs | at86rf230.ko fakehard.ko ieee802154.ko spi_atben.ko usbcore.ko | 15:54 |
| blogic | good | 15:54 |
| blogic | check 1 more thing | 15:54 |
| jivs | ok | 15:54 |
| blogic | ..../root-lantiq/etc/modules.d/ | 15:55 |
| blogic | oops | 15:55 |
| blogic | ..../root-xburst/etc/modules.d/ | 15:55 |
| jivs | ok | 15:55 |
| jivs | 20-crc-ccitt 20-usb-core 90-ieee802154 91-mac802154 92-fakehard 92-fakelb 93-spi-dev | 15:55 |
| blogic | you should corresponding files there that tell the system to insmod the drivers that will now be part of the image | 15:55 |
| blogic | ok at86rf230 is missing | 15:56 |
| blogic | let me look at wpan.mk 1 moment please | 15:56 |
| jivs | ok | 15:56 |
| blogic | hmmmm | 15:58 |
| blogic | ok i will need to look indetail | 15:58 |
| blogic | you can flash the image but will need to manually insmod the modules atm | 15:58 |
| blogic | i will ping you when i have a update wpan.mk | 15:58 |
| jivs | sure | 15:58 |
| blogic | i will build an image in a sec to play around | 15:58 |
| jivs | okay :-) | 15:59 |
