2011-11-30 03:34 <wpwrak> how long does the RTC actually maintain time ?
2011-11-30 03:34 panda|x201 joined #qi-hardware
2011-11-30 03:48 <kristianpaul> nothing
2011-11-30 03:48 <kristianpaul> well, seconds i guess
2011-11-30 03:51 <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.
2011-11-30 03:52 <kristianpaul> bit? like the first palm m100 ;)
2011-11-30 03:55 <wpwrak> hmm, the diode has a reverse current of about 2 uA
2011-11-30 04:01 <wpwrak> hmm, simulation says that this should be sufficient for about 4 seconds
2011-11-30 04:02 <wpwrak> kristianpaul: your estimate wasn't so bad :)

2011-11-30 04:10 kristianpaul joined #qi-hardware
2011-11-30 04:21 <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.
2011-11-30 04:22 <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.

2011-11-30 11:27 <kristianpaul> hehe :-), just getting ready to go work :)

2011-11-30 11:37 <kristianpaul> btw is taking so long the package with stickers/brochure to arrive
2011-11-30 11:38 <kristianpaul> but i guess no rush, a package from Artyom took near 3 months to get here..
2011-11-30 11:38 <wolfspraul> who knows
2011-11-30 11:38 <kristianpaul> indeed
2011-11-30 11:39 <kristianpaul> must go, read you later
2011-11-30 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
2011-11-30 11:39 <kristianpaul> :-|
2011-11-30 11:39 <wolfspraul> Mirko dropped a letter (unregistered, untrackable) into the mail but it never arrived
2011-11-30 11:39 <wolfspraul> that was the only case ever
2011-11-30 11:39 <wolfspraul> so let's see
2011-11-30 11:39 <wolfspraul> maybe it arrives, maybe not
2011-11-30 11:39 <wolfspraul> if not, then we need to send another one...
2011-11-30 11:40 <kristianpaul> lets wait
2011-11-30 11:40 <kristianpaul> will be the first package i fail to receiver, hope not

2011-11-30 14:37 <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?
2011-11-30 14:39 <blogic> "lsmod | grep at" ?
2011-11-30 14:40 <antoniodariush> blogic, nothing
2011-11-30 14:40 <blogic> then i would assume that the image lacks atben support
2011-11-30 14:44 <antoniodariush> even though I have these http://pastebin.com/5TnB5Fkk
2011-11-30 14:44 <antoniodariush> ?
2011-11-30 14:44 <blogic> hmmmm
2011-11-30 14:44 <blogic> not sure
2011-11-30 14:46 <wpwrak> maybe the module isn't loaded ?
2011-11-30 14:47 <antoniodariush> what u mean by loaded
2011-11-30 14:49 <wpwrak> and you also need CONFIG_IEEE802154_DRIVERS, CONFIG_SPI_BITBANG, CONFIG_SPI_GPIO
2011-11-30 14:49 <blogic> antoniodariush: find /lib/modules/ | grep at
2011-11-30 14:50 <blogic> are they even installed int he rfs ?
2011-11-30 14:50 <wpwrak> heh :)
2011-11-30 14:50 <wpwrak> and if they exist, lsmod will show is they're being used

2011-11-30 14:59 <jivs> /lib/modules/3.0.0/spi_atben.ko
2011-11-30 14:59 <jivs> for the find command above
2011-11-30 15:00 <jivs> but nothing for lsmod |grep at
2011-11-30 15:00 <blogic> there will be some missing package then
2011-11-30 15:01 <blogic> causing those packets to not be installed
2011-11-30 15:01 <blogic> causing those packets to not be inserted
2011-11-30 15:02 <jivs> okay i will try to reflash by adding more packages as wpwrak suggested..
2011-11-30 15:02 <blogic> xiangfu: is this the latest http://patchwork.openwrt.org/patch/1439/ ?
2011-11-30 15:02 <blogic> ah he is not online
2011-11-30 15:03 <blogic> does xiangfu have access to target/linux/xburst in the owrt repo ?
2011-11-30 15:03 <blogic> it seems weird that i need to merge this for him
2011-11-30 15:06 <jivs> wpwrak, is IEEE802154_DRIVERS same as PACKAGE_kmod-ieee802154 . I don't see any package with ieee on its name in my toolchain
2011-11-30 15:23 panda|x201 joined #qi-hardware
2011-11-30 15:34 <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
2011-11-30 15:35 <blogic> wpwrak: i asusme he uses this http://phrozen.org/wpan.mk
2011-11-30 15:35 <blogic> i gave that link to xiangfu and i assume he integrated it to the qi tree
2011-11-30 15:36 <jivs> okay
2011-11-30 15:36 <wpwrak> this looks like a typo: CONFIG_IEEE802154_DRIVER vs. CONFIG_IEEE802154_DRIVERS
2011-11-30 15:37 <blogic> indeed
2011-11-30 15:37 <wpwrak> also, no =y needed for CONFIG_MAC802154 ?
2011-11-30 15:37 * blogic looks
2011-11-30 15:37 arti joined #qi-hardware
2011-11-30 15:38 <blogic> nope
2011-11-30 15:38 <blogic> that is correct
2011-11-30 15:39 <blogic> the CONFIG_IEEE802154_DRIVER=y vs CONFIG_IEEE802154_DRIVERS=y  looks like the candidate for the borkage
2011-11-30 15:39 <blogic> (missing S at the end)
2011-11-30 15:45 <blogic> jivs: i am almost certain this is the case
2011-11-30 15:45 <blogic> the dependency chain of at86rf230 is broken without that symbol
2011-11-30 15:45 <blogic> jivs: did you build the image yourself ?
2011-11-30 15:45 <jivs> yes blogic
2011-11-30 15:45 <antoniodariush> so i guess we need to wait for xiangfu ?
2011-11-30 15:46 <jivs> how can we fix this on our image? if we can
2011-11-30 15:46 <blogic> you need to rebuild the image
2011-11-30 15:46 <blogic> vi package/kernel/module/wpan.mk
2011-11-30 15:46 <jivs> ok
2011-11-30 15:46 <blogic> go to the line that has CONFIG_IEEE802154_DRIVER=y \ and add a S before the =y
2011-11-30 15:46 <blogic> then do
2011-11-30 15:47 <blogic> rm -r tmp/ && make menuconfig      (save and exit to update the config
2011-11-30 15:47 <jow_laptop> (make defconfig)
2011-11-30 15:47 <blogic> make package/kernel/clean && make V=99
2011-11-30 15:47 <blogic> :D
2011-11-30 15:47 <blogic> jow_laptop: ok
2011-11-30 15:47 <blogic> rm -r tmp/ && make defconfig && make package/kernel/clean && make V=99
2011-11-30 15:47 <blogic> that will build an image with the fix applied
2011-11-30 15:48 <blogic> before flashing it you can see if the file is now included
2011-11-30 15:48 <blogic> you can do so by calling
2011-11-30 15:49 <blogic> ls  build_dir/target-mips_r2_uClibc-0.9.32/root-xburst/lib/modules/
2011-11-30 15:49 <jivs> thank u blogic and jow_laptop , i am building new image now
2011-11-30 15:49 <blogic> the path might be slightly different to build_dir/target-mips_r2_uClibc-0.9.32/root-xburst/lib/modules/
2011-11-30 15:49 <blogic> is the nanonote mips or mipsel ?
2011-11-30 15:50 <jow_laptop> mipsel
2011-11-30 15:50 <jivs> mipsel
2011-11-30 15:51 <blogic> ok
2011-11-30 15:52 <blogic> it will be  build_dir/target-mipsel_r2_uClibc-0.9.32/root-xburst/lib/modules/... in that case
2011-11-30 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
2011-11-30 15:52 * blogic might continue to integrate 802.15.4 in owrt tonight
2011-11-30 15:53 <jivs> okay
2011-11-30 15:54 <jivs> the folder now had these files af_802154.ko  crc-ccitt.ko  fakelb.ko      mac802154.ko  spidev.ko
2011-11-30 15:54 <jivs> at86rf230.ko  fakehard.ko   ieee802154.ko  spi_atben.ko  usbcore.ko
2011-11-30 15:54 <blogic> good

2011-11-30 15:55 <blogic> you should corresponding files there that tell the system to insmod the drivers that will now be part of the image
2011-11-30 15:56 <blogic> ok at86rf230 is missing
2011-11-30 15:56 <blogic> let me look at wpan.mk 1 moment please

2011-11-30 15:58 <jivs> sure
