2011-03-02 00:05 <Fusin> ok, time for sleep
2011-03-02 00:05 <Fusin> cu
2011-03-02 00:06 <Fusin> n8
2011-03-02 00:07 <tuxbrain> ladies(if any)..., gentleman(also if any).... I have a working (or at least ejecutable) avr-toolchain + avrdude patched installed on my NN.....YIPIKAYHEY!!!!!!
2011-03-02 00:07 <tuxbrain> the problem is that I'm getting out of space on NN only 57Mb left
2011-03-02 00:08 <tuxbrain> so I can't install anything with opkg
2011-03-02 00:09 <tuxbrain> now that that speed has been improved we can't change the partition size to something a litlle bit bigger?
2011-03-02 00:09 <wpwrak> ;-))
2011-03-02 00:10 <wpwrak> you could offer a web-based compilation service, let the ben connect to it via cdc_ether
2011-03-02 00:11 <xiangfu> tuxbrain: congratulations,
2011-03-02 00:11 <xiangfu> tuxbrain: I would like make help make arv-toolchian + avrdude as openwrt packages.
2011-03-02 00:11 <xiangfu> :)
2011-03-02 00:12 <tuxbrain> xiangfu: I would love to have it, really, but I can guess it will not be trivial
2011-03-02 00:14 <tuxbrain> I have an installation error on gcc I have to solve manually copying reanaming the executable gcc-cross to avr-gcc manually, and avr-lib needs native ->avr copilation toolchain .... gooddamn  I'm barelly not knowing what I'm saying
2011-03-02 00:15 <tuxbrain> avr-lib->avr-libc
2011-03-02 00:15 <tuxbrain> patched avrdude yes is trivial :)
2011-03-02 00:18 <tuxbrain> moving the 90Mb of the toolchain to uSD to do some test
2011-03-02 00:18 <tuxbrain> I will have to mount the extra Nand space to install all this...
2011-03-02 00:19 <tuxbrain> why NN live is never easy...
2011-03-02 00:19 <tuxbrain> ?
2011-03-02 00:19 <wpwrak> it is if you cross-compile ;-)
2011-03-02 00:20 <tuxbrain> I want to cross-compile :) but in NN :P
2011-03-02 00:23 <tuxbrain> there is anything I can empty on a vanila lastest distro  to gain some space? I was unable to install gcc-mips and libgcc?, only 115K left
2011-03-02 00:28 <tuxbrain> well dudes time to some sleep , let's see if tomorrow I fin a way to fit all that(gcc-mips, libgcc, avr-toolchain, avr-dude, arduino libs and arduino template Makefile) on NAND somehow to free the precious GPIO pins to do the test
2011-03-02 00:33 <wpwrak> tuxyeah, it would kinda suck if you needed a memory card for this ;-)))
2011-03-02 00:33 <wpwrak> bah, tuxbrain: ...
2011-03-02 00:37 <tuxbrain> we have 2Gb on nand there has to be a way to fit I guess :)
2011-03-02 00:38 <tuxbrain> tuxyeah XD
2011-03-02 00:38 <Jay7> nice nickname :)
2011-03-02 00:39 <Jay7> is building native-sdk-image for nanonote
2011-03-02 00:40 <Jay7> -> sleep
2011-03-02 00:40 <tuxbrain> well I will use it when I finaly make my arduino blink at NN will :P

2011-03-02 01:25 <kristianpaul> tuxbrain_away: felicitaciones !
2011-03-02 01:44 <kristianpaul> (UIO) he, finally !
2011-03-02 01:45 <kristianpaul> ah.. 2007
2011-03-02 01:48 <kristianpaul> uses xserver-xfbdev in his laptop
2011-03-02 01:52 <kristianpaul> go back to do so C readings
2011-03-02 02:03 <RylandAlmanza> Hi, I'm a programmer thinking of buying a nanonote. Would this be suitable for my purposes? I would generally be using it for programming, but I would also like to know what kind of limitations there are on wifi.
2011-03-02 02:04 <wolfspraul> sounds like it is very suitable, yes
2011-03-02 02:04 <wolfspraul> what kind of programming interests you?
2011-03-02 02:05 <RylandAlmanza> a very broad range, but how about webdesign? Even if I didn't have wifi, it would still be good for developing and testing websites, correct?
2011-03-02 02:06 <wolfspraul> no
2011-03-02 02:06 <wolfspraul> do you like large screens?
2011-03-02 02:07 <wolfspraul> the NanoNote is a very mobile small thingie. no touch-screen, only keyboard.
2011-03-02 02:07 <RylandAlmanza> I don't mind small screens, but I didn't think about what that would do to the websites
2011-03-02 02:07 <wolfspraul> it's cpu power is limited, 336 mhz mips, 32 mb memory
2011-03-02 02:07 <RylandAlmanza> would it be somewhat like viewing a website on a cell phone?
2011-03-02 02:07 <wolfspraul> so depends on what you think about when you say 'websites'
2011-03-02 02:07 <wolfspraul> no
2011-03-02 02:07 <wolfspraul> the cell phones have crazily optimized browsers
2011-03-02 02:08 <RylandAlmanza> ah, I see
2011-03-02 02:08 <wolfspraul> there is no way the NanoNote can match that
2011-03-02 02:08 <wolfspraul> the browser you can find useful on NanoNote is more something like lynx, elinks, w3m, netsurf
2011-03-02 02:08 <wolfspraul> if that kind of challenge interests you, go for it
2011-03-02 02:08 <wolfspraul> if you compare with a browser on a recent iphone/android, don't go there it will disappoint you
2011-03-02 02:09 <RylandAlmanza> Anyway, webdesign was just an Idea. I would be content with even just console based applications
2011-03-02 02:09 <wolfspraul> he
2011-03-02 02:09 <wolfspraul> that sounds more NanoNote-likish
2011-03-02 02:09 <RylandAlmanza> lol
2011-03-02 02:09 <wolfspraul> http://en.qi-hardware.com/wiki/Applications
2011-03-02 02:09 <wolfspraul> have you seen this?
2011-03-02 02:10 <wolfspraul> browsing through this list may give you a rough idea where things are today, at least in OpenWrt
2011-03-02 02:10 <wolfspraul> there is also Jlime
2011-03-02 02:10 <RylandAlmanza> Ok, thanks, I'll have a look at it right now :)
2011-03-02 02:10 <wolfspraul> on the programming side, things that are 'not bad' today are guile, python, perl, php, bash, gforth - in GUI toolkits sdl, qt, gtk
2011-03-02 02:12 <RylandAlmanza> Sounds like a blast to me! Right now I'm stuck with trying to program on a Nintendo DS with linux installed on a hombrew cart... Doesn't work very well...
2011-03-02 02:14 <RylandAlmanza> But, by "not bad," could you be more specific? What kinds of things wouldn't work? I'm pretty sure I've got my mind set on buying one of these no matter what, but I'd like to know anyway.
2011-03-02 02:15 <wolfspraul> hmm. I'm just one guy, I cannot qualify so many different toolkits and languages.
2011-03-02 02:15 <wolfspraul> when I say 'not bad' that means I think it works, but there may be bugs
2011-03-02 02:15 <wolfspraul> when can you say 'pythin is great on the NanoNote'?
2011-03-02 02:15 <wolfspraul> I think I can only say that if I know several very active Python app development are going on.
2011-03-02 02:16 <wolfspraul> and there is someone here in irc who says "Python on the NanoNote is great"
2011-03-02 02:17 <wolfspraul> like for example we have emacs on the NanoNote
2011-03-02 02:17 <wolfspraul> but emacs is big, and whether it's 'good' or 'not good' depends on many details
2011-03-02 02:17 <wolfspraul> for emacs, David Kuehling who is sometimes on this list (nick: dvdk) can give you a definitive and honest answer where emacs stands today
2011-03-02 02:17 <wolfspraul> for guile, maybe zedstar
2011-03-02 02:18 <wolfspraul> we have working sdl, qt and gtk apps on the NanoNote, so those toolkits definitely work
2011-03-02 02:19 <RylandAlmanza> Ok, thanks for all the help, I'm going to keep looking over that wiki page, and I'll let you know if I have anymore questions. :)
2011-03-02 02:20 <wolfspraul> sure, thanks for your questions, and stop by anytime...
2011-03-02 02:20 <wolfspraul> are you in the US?
2011-03-02 02:20 <wolfspraul> at this time it's quiet here because of timezone
2011-03-02 02:20 <RylandAlmanza> Yes, I am.
2011-03-02 02:20 <wolfspraul> the Europeans are mostly asleep
2011-03-02 02:20 <RylandAlmanza> Ah.
2011-03-02 02:20 <wolfspraul> we have some 'Americans', though mostly in the south :-) (Colombia, Argentina)
2011-03-02 02:21 <wolfspraul> and I'm here, and some other Asian early rises...
2011-03-02 02:21 <RylandAlmanza> What time is it where you are?
2011-03-02 02:21 <wolfspraul> 10:20 am
2011-03-02 02:21 <wolfspraul> beijing
2011-03-02 02:22 <RylandAlmanza> Oh, cool. Where did you learn english so well?
2011-03-02 02:24 <wolfspraul> in the US
2011-03-02 02:24 <wolfspraul> worked in Connecticut for over 10 years
2011-03-02 02:24 <wolfspraul> if you order a NanoNote (just explaining some background info), it will come from Hong Kong with Fedex
2011-03-02 02:25 <wolfspraul> it costs about 25 USD shipping, and takes 3-4 days to arrive
2011-03-02 02:25 <RylandAlmanza> Ok, I'm willing to pay 25 USD shipping, and I actually would've expected it to take longer than that. Thanks for the info :)
2011-03-02 02:26 <wolfspraul> we would be very happy to welcome you to the club, sounds like you are doing closely related things already with Nintendo Linux hacking etc.
2011-03-02 02:27 <RylandAlmanza> Yeah, just very hard with a Nintendo DS, because it wasn't meant for that kind of stuff. A nanonote would definately be much more suitable.

2011-03-02 03:16 <rjeffries_> wolfspraul when you listed a few programming languages that are "not bad" on Ben NN for that guy, you missed Lua. ;)
2011-03-02 03:17 <rjeffries_> compared to programming on his Nintendo DS vs Ben NN, he will think he died and went to heaven
2011-03-02 03:26 <wolfspraul> Lua, true
2011-03-02 03:26 <wolfspraul> sorry about that
2011-03-02 03:27 <wolfspraul> I just was listing off the top of my mind
2011-03-02 03:27 <wolfspraul> we have so many :-)
2011-03-02 03:27 <wolfspraul> I want to consolidate a little, make a list of 'officially' supported programming languages
2011-03-02 03:27 <wolfspraul> but it's so hard to qualify how good language support actually is
2011-03-02 03:28 <wolfspraul> because every language ties into libraries, extensions, modules. some things may be hopelessly non-performant, so it's better to not even claim they exist. and so on.
2011-03-02 03:28 <wolfspraul> we get to it over time
2011-03-02 03:29 <rjeffries_> yup
2011-03-02 03:29 <wolfspraul> best is if every language is 'alive' in the sense that there are actively maintained programs/apps/games using it, with people behind.
2011-03-02 03:29 <rjeffries_> here is a cool little USB power supply http://jeelabs.org/2011/03/02/new-usb-power-option/
2011-03-02 03:29 <wolfspraul> gotta go, bbiab
2011-03-02 03:29 <rjeffries_> a few people here have used Lua if I recall correctly
2011-03-02 03:29 <rjeffries_> ciao
2011-03-02 03:42 <roh> wpwrak: http://jeelabs.com/products/uart-plug
2011-03-02 03:42 <roh> uart for i2c... and the chip can do spi too. and its cheap. can be used with a ubb ;)
2011-03-02 03:49 <qi-bot> [commit] Xiangfu Liu: reflash_ben.sh, new option b k r, reboot device after reflash http://qi-hw.com/p/openwrt-xburst/a8f5b61
2011-03-02 05:21 <wpwrak> (and some of the "americans" only come back after dinner ;-)
2011-03-02 05:24 <wpwrak> roh: (uart) nice :) but i'm actually more after the avr than the uart functionality per se. the uart doesn't do much for me, but having an avr is good.
2011-03-02 05:25 <zrafa> yeah, we eat from this part
2011-03-02 05:25 <wpwrak> needs to make progress with the spectrum analyzer so that i have an excuse for cutting the wifi ;-)
2011-03-02 06:26 <aw> wpwrak, have you ever used PPTC resettable polyfuse?
2011-03-02 06:28 <wpwrak> no, i haven't used polyfuses yet
2011-03-02 06:32 <kyak> wow.. i really do know how to waste my time. Building and running malta target in qemu is so easily done with openwrt, just a matter of few "clicks"
2011-03-02 06:32 <kyak> why the hell i did that by hand..
2011-03-02 06:33 <wpwrak> kyak: for wasting your time, try building your kernels on the ben. that should do nicely :)
2011-03-02 06:34 <aw> wpwrak, thanks.
2011-03-02 06:34 <kyak> i tried, it doesn't waste my time, it is wasting Ben's time :)
2011-03-02 06:36 <kyak> ok, what i actually wanted to see is if kexec will work on mipsel malta
2011-03-02 06:42 <wpwrak> kyak: what's the actual problem ? that it is supposed to work but for some reason doesn't ? or do we have a more specific situation ?
2011-03-02 06:43 <kyak> well, it _should_ work, and some people even reported that it works on mips with their routers. And there are even some patches, but after all it just doesn't owkr
2011-03-02 06:44 <kyak> the last thing i see before everything hangs is "Switching no new kernel bla-bla-... Bye.."
2011-03-02 06:44 <wpwrak> hmm, nasty then
2011-03-02 06:44 <kyak> yes, very annoying,too
2011-03-02 06:44 <wpwrak> to kexec(1) seems to be happy
2011-03-02 06:45 <kyak> and the worst thing is that i feel that this is beyond my knowledge
2011-03-02 06:46 <kyak> i wil try with qemu as a last resort, then i'll give up :)
2011-03-02 06:46 <wpwrak> there are worse situations :) like realizing that this ought to be within your knowledge but that you really shouldn't sink that day or two into it just now :)
2011-03-02 06:48 <kyak> yeah, this is bad
2011-03-02 06:48 <wpwrak> kyak: if you have a serial console, that may help. could be that the new kernel starts but dies later on.
2011-03-02 06:49 <kyak> wpwrak: no serial console -\ This is i thought qemu might help
2011-03-02 06:50 <wpwrak> kyak: you could also put a loop somewhere early. e.g., outputting something on UBB :)
2011-03-02 06:50 <wpwrak> (something) like a square wave
2011-03-02 06:50 <wpwrak> that way, you'd see if you reach that point
2011-03-02 06:50 <kyak> i.e. this needs to be done in kernel code?
2011-03-02 06:51 <wpwrak> debugging the early boot code is no fun, because you don't have printk
2011-03-02 06:51 <kyak> outputting something to UBB
2011-03-02 06:51 <kyak> oh, there are printk's
2011-03-02 06:51 <kyak> at least during the "Bye.." message :)
2011-03-02 06:51 <wpwrak> yes, this looks like something that needs to be done in the kernel
2011-03-02 06:52 <wpwrak> the question is how far you get after the "bye"
2011-03-02 06:52 <kyak> yes, this is a good question
2011-03-02 06:52 <wpwrak> that may be very short. e.g., you may crash within 1-2 instructions if you have the wrong address
2011-03-02 06:53 <wpwrak> if you make it to the new kernel, it may still die very early -> low-level uart output or toggling a ubb line
2011-03-02 06:53 <kyak> you are right..
2011-03-02 06:53 <wpwrak> if you make it a little further, you want console output
2011-03-02 06:53 <wpwrak> could also be that everything is fine but it just can't bring up the lcm
2011-03-02 06:53 <kyak> sounds like debugging the kernel is a nigthmare :)
2011-03-02 06:54 <wpwrak> debugging the early kernel is hard. once you make it a bit further, it gets easier
2011-03-02 06:55 <wpwrak> over here, you can see my credentials on the topic :) http://bootimg.sourceforge.net/
2011-03-02 06:56 <kyak> wow! i remember you mentioned you planted a tree in the kernel :)
2011-03-02 06:57 <wpwrak> ah no, it's not that one ;-) my seeds are things like the fat file system and initrd
2011-03-02 06:57 <kyak> but that you were a predecessor of kexec!!
2011-03-02 06:57 <kyak> very cool :)
2011-03-02 06:58 <kyak> seems that i could use your hand
2011-03-02 06:58 <wpwrak> conceptually, yes. kexec was an independent implementation. peter anvin and i helped to smoothen it (kexec) a little, though. and i bribed linus with a beer to consider it for inclusion into mainline ;-)
2011-03-02 06:59 <kyak> ah, so this is how it works! corruption everywhere ;)
2011-03-02 07:00 <wpwrak> indeed ;-)
2011-03-02 07:03 <kyak> wpwrak: i remember you said once that you are unemployed at the moment. Is it still the case? (i don't have anything to offer to you, but it seems that you are the man of many talents)
2011-03-02 07:04 <wpwrak> yeah, qi-hw is still my full-time hobby. i plan to keep it this way for at least one more month, then i'll have to start looking for some real income
2011-03-02 07:06 <kyak> your employer will be lucky to have you :)
2011-03-02 07:06 <wpwrak> thanks ;-)
2011-03-02 07:09 <kyak> root@OpenWrt:/# kexec -l /lib/vmlinux.elf
2011-03-02 07:09 <kyak> Invalid memory segment 0x100000 - 0xeaffff
2011-03-02 07:11 <kyak> coudl be a problem because this vmlinux.elf has ramfs built-in..
2011-03-02 07:11 <wpwrak> hmm. maybe. if it;'s truly too big, yes
2011-03-02 07:12 <kyak> yeah, 43Mb
2011-03-02 07:12 <kyak> will try with a bare kernel..
2011-03-02 07:13 <wpwrak> yeah, 43 MB sounds unhealthy for a 32 MB machine ;)
2011-03-02 07:14 <kyak> nah, i boot with -m 256
2011-03-02 07:16 <kyak> (start qemu, i mean)
2011-03-02 07:18 <wpwrak> hmm, qemu may change the picture
2011-03-02 07:19 <kyak> # kexec -l /lib/vmlinux.bin
2011-03-02 07:19 <kyak> Cannot determine the file type of /lib/vmlinux.bin
2011-03-02 07:19 <kyak> hmm ok, so kexec insists on having elf image..
2011-03-02 07:19 <wpwrak> how about adding a serial console ?
2011-03-02 07:19 <kyak> to Ben?
2011-03-02 07:20 <wpwrak> kexec also has an option -t to force the file type. a binary without headers or such may need this.
2011-03-02 07:20 <kyak> ok, will try that
2011-03-02 07:20 <wpwrak> (serial console) yes, to the ben
2011-03-02 07:20 <wpwrak> for kernel hacking, a serial console is quite handy
2011-03-02 07:21 <wpwrak> it lets you do things like putting a   cli(); while (1);  right after some point of interest, and you'll still see everything that happened shortly before
2011-03-02 07:22 <kyak> yeah, i might want to consider that.. But first i need to buy this ttl<->COM port cable
2011-03-02 07:22 <wpwrak> or another ben :)
2011-03-02 07:22 <kyak> oh!
2011-03-02 07:22 <kyak> what a great idea :)
2011-03-02 07:23 <wpwrak> is working hard on increasing wolfgang's sales :)
2011-03-02 07:23 <kyak> i was considering the second ben anyway. Was waiting for some confirmation about wifi card from wolfspraul :)
2011-03-02 07:24 <wpwrak> seems that all he has left are somewhat questionable wifi cards. i think pulster may have some, though.
2011-03-02 07:25 <wpwrak> hmm, time for a siesta before i fall off the chair :)
2011-03-02 07:25 <kyak> now that you've given me the use case for the second Ben, this sale could work without the wifi card :)
2011-03-02 07:26 <wpwrak> ;-)
2011-03-02 07:27 <kyak> what i'm hearing? Mighty Werner is going to sleep? :)
2011-03-02 07:31 <kyak> have a good rest then ;)
2011-03-02 08:12 <Jay7> morning
2011-03-02 08:12 <Jay7> kyak: buy me one ttl<->com too ;)
2011-03-02 08:13 <Jay7> at least say me how to find it :)
2011-03-02 08:17 <kyak> Jay7: do you mean, buy you another Ben? :)
2011-03-02 08:19 <Jay7> kyak: no, I mean only that special cable :)
2011-03-02 08:22 <kyak> insane... they ask ~1200 roubles (42 USD) for such cable
2011-03-02 08:22 <kyak> http://ru.rsdelivers.com/product/ftdi-chip/ttl-232r-3v3-we/usb-serial-ttl-cable-ft232rq-ttl-232r/0429303.aspx
2011-03-02 08:22 <kyak> no way
2011-03-02 08:24 <kyak> makes me angry
2011-03-02 08:24 <kyak> this costs nothing
2011-03-02 08:24 <kyak> it's 50 cent
2011-03-02 08:24 <kyak> in China
2011-03-02 08:25 <tuxbrain> jay kyak, I bought mine from here http://apple.clickandbuild.com/cnb/shop/ftdichip?productID=53&op=catalogue-product_info-null&prodCategoryID=105
2011-03-02 08:25 <kyak> i would hang such "entrepreneurs"
2011-03-02 08:25 <kyak> tuxbrain: wouldn't be much cheaper considering delivery -\
2011-03-02 08:25 <Jay7> kyak: I'm reading logs
2011-03-02 08:25 <xiangfu> kyak: Jay7 you can buy the usb-jtag/serial board which is used in MilkyMist one :)
2011-03-02 08:26 <Jay7> kyak: iirc, qemu-system-* can't do kexec
2011-03-02 08:26 <kyak> Jay7: so far, it seems so,, kexec can't load the elf image
2011-03-02 08:26 <tuxbrain> xiangfu: this will also work as usb-3v3tty interface?
2011-03-02 08:26 <tuxbrain> for NN?
2011-03-02 08:26 <xiangfu> sure
2011-03-02 08:27 <kyak> xiangfu: what would be the price? :)
2011-03-02 08:27 <Jay7> at least all my attempts with qemu-system-arm was failed
2011-03-02 08:28 <tuxbrain> xianfu any howto about this?, this can make the jtag board also selled as NN complement!
2011-03-02 08:28 <Jay7> wrt cable
2011-03-02 08:29 <xiangfu> tuxbrain: I am using usb-->serial/12-->TTL. which is very big. usb<->jtag is much better :)
2011-03-02 08:29 <Jay7> is there any scheme available to do it by hands?
2011-03-02 08:29 <Jay7> or at least 3.3v <-> 5v convertor
2011-03-02 08:29 <xiangfu> tuxbrain: I will take a picture . wait one moment.
2011-03-02 08:30 <kyak> xiangfu: hm, cool. So you Ben has jtag interface?
2011-03-02 08:31 <xiangfu> tuxbrain, kyak , I guess the jtag also works fine in Ben NanoNote.
2011-03-02 08:31 <xiangfu> kyak: since the another serial can switch to JTAG pins
2011-03-02 08:31 <kyak> Jay7: http://www.ftdichip.com/FTProducts.htm something of thes i think is used..
2011-03-02 08:32 <kyak> xiangfu: "another serial"?
2011-03-02 08:33 <tuxbrain> wow, NN will pass to have no connectivity to SPI/jtag/serial/w6lowpan , not bad
2011-03-02 08:33 <xiangfu> kyak: http://en.qi-hardware.com/wiki/Serial_console#Hardware_mod_to_have_a_pluggable_serial_port
2011-03-02 08:33 <xiangfu> kyak: see the first picture comment.
2011-03-02 08:34 <xiangfu> it's not /dev/ttyS1. it is /dev/ttyS0 have four pin out. two under battery. the other two is share with JTAG pins.
2011-03-02 08:35 <xiangfu> kyak: the TP4 and TP5 can switch by software  JTAG <--> ttyS0
2011-03-02 08:35 <xiangfu> kyak: for now. it's ttyS0. I think kristianpaul is using this port connect the GPS.
2011-03-02 08:36 <kyak> ok, so it requires some modifications
2011-03-02 08:36 <kyak> (using jtag)
2011-03-02 08:36 <kyak> using usb-ttl cable we can simply connect to TX/RX/GND pins under the battery
2011-03-02 08:37 <kyak> therefore, the jtag board for MM can't be used without disassembling Ben?
2011-03-02 08:38 <xiangfu> kyak: correct.
2011-03-02 08:38 <tuxbrain> kyak I supose if you want the jtag funcionallity yes but if you can live only with serial I suppose you can those under the battery , isn't it xiangfu?
2011-03-02 08:39 <tuxbrain> kyak also if you can live without the ben keyboard meanwhile you have serial plugged
2011-03-02 08:41 <kyak> hm
2011-03-02 08:41 <kyak> do you mean that serial port and keyboard share some pins?
2011-03-02 08:42 <kyak> it means that the second Ben can't be used (via keyboard at least) as a ttl cable :)
2011-03-02 08:43 <kyak> Jay7: random people report that kexec is working with qemu-system-arm: http://comments.gmane.org/gmane.linux.kernel.kexec/3627
2011-03-02 08:43 <xiangfu> tuxbrain: correct.
2011-03-02 08:44 <Jay7> kyak: I've used it with -M akita mostly
2011-03-02 08:44 <Jay7> so may be just this machine emulation can't do kexec
2011-03-02 08:44 <kyak> maybe..
2011-03-02 08:45 <xiangfu> kyak: when enable the serial console understand battery. the keyboard have problem when press Ctrl/Alt/Red + KEYS
2011-03-02 08:46 <kyak> xiangfu: ok..
2011-03-02 08:46 <xiangfu> kyak: the problem is only the first time press.
2011-03-02 08:46 <xiangfu> kyak: like. 1. Shift + q = q, 2. Shift + q = Q.
2011-03-02 08:47 <kyak> this is strange
2011-03-02 08:47 <xiangfu> kyak: the serial RX pin share with KEYIN_8.
2011-03-02 08:48 <kyak> oh, ok
2011-03-02 08:50 <xiangfu> tuxbrain: http://en.qi-hardware.com/wiki/File:IMG_0401.JPG
2011-03-02 08:50 <xiangfu> tuxbrain: sorry. forget to change file name. how to change name after upload file?
2011-03-02 10:53 <kristianpaul> xiangfu: (how to change) just move it
2011-03-02 10:56 <kristianpaul> xiangfu: kyak http://en.qi-hardware.com/wiki/File:IMG_0082.JPG
2011-03-02 10:56 <kristianpaul> Yes, but now i see xiangfu is using the rx/tx under the batery (i wonder why..)
2011-03-02 10:57 <kyak> kristianpaul: so you keep your Ben opened?
2011-03-02 10:57 <kristianpaul> (jtag and ben nanonote) a short intro about it will be nice :-) (I dunno how usefull)
2011-03-02 10:57 <kristianpaul> kyak: nope
2011-03-02 10:57 <kristianpaul> kyak: i soldered and make a connector in the back
2011-03-02 10:58 <kyak> kristianpaul: coudl you post more photos of this? :)
2011-03-02 10:58 <kristianpaul> wait a min
2011-03-02 10:58 <kyak> is really interesting how it looks like
2011-03-02 10:58 <kyak> how do you attach GPS module to Ben?
2011-03-02 10:59 <kristianpaul> usign that connecto
2011-03-02 10:59 <kristianpaul> wait a min
2011-03-02 11:00 <kyak> sure
2011-03-02 11:00 <dvdk> so yesterday i missed the uio flamewar ?
2011-03-02 11:00 <kyak> uio?
2011-03-02 11:00 <kyak> hi David :)
2011-03-02 11:01 <dvdk> morning.  yeah suggested to wpwrak he could use linux new UIO (userspace i/o) to help with his UBB kernel dirver project.
2011-03-02 11:01 <dvdk> i think the same approach will be helpful with the mplayer video driver for jz47xx accelerated output
2011-03-02 11:02 <dvdk> (mplayer/vidix is were i stumbled over uio)
2011-03-02 11:02 <kyak> well, i don't quite understand what is it, but i like the words "mplayer jz47xx accelerated output" together :)
2011-03-02 11:03 <dvdk> http://sourceforge.net/projects/mplayer-jz47xx/
2011-03-02 11:03 <dvdk> going to hack mplayer to dlopen and use jz47xx_vid.so
2011-03-02 11:03 <dvdk> so we can package and develope these two parts separately for now
2011-03-02 11:03 <dvdk> first code is going to be 100% userspace (mmap /dev/mem), later move parts to kernel
2011-03-02 11:04 <kyak> oh cool
2011-03-02 11:04 <kyak> so you are on it :)
2011-03-02 11:05 <dvdk> yeah, may take only a few more weeks.
2011-03-02 11:05 <dvdk> so don't wonder if i make some minor patches to the mplayer package
2011-03-02 11:06 <dvdk> that's going to be the hook needed to load the external jz47xx driver
2011-03-02 11:06 <kyak> do whatever you need to do, i'm only glad :)
2011-03-02 11:06 <kyak> so it's going to be -vo vidix-jz ?
2011-03-02 11:07 <dvdk> kyak: something like that, yes.
2011-03-02 11:07 <dvdk> more like fbdev:vidix ?
2011-03-02 11:07 <kyak> very exciting
2011-03-02 11:07 <dvdk> but first it needs to work
2011-03-02 11:07 <dvdk> for now i only have the basic vidix skeleton
2011-03-02 11:07 <dvdk> no functionality
2011-03-02 11:09 <dvdk> ok need to do some work
2011-03-02 11:10 <kristianpaul> kyak: http://kristianpaul.org/~paul/tmp/benserial/ fell ree to upload to qi wiki, i dint have time now
2011-03-02 11:10 <kristianpaul> gotta go (work)
2011-03-02 11:10 <kristianpaul> s/ree/free
2011-03-02 11:11 <kyak> kristianpaul: thanks, i'll have a look
2011-03-02 12:43 <wpwrak> kyak: (need sleep) yeah. ubuntu and usrp2_fft killed me yesterday.
2011-03-02 12:45 <wpwrak> kyak: (serial) there is one uart but it has two sets of pins. one set is shared with jtag while the other is only uart or gpio. alas, we have the keyboard on one of the uart/gpio lines. the uart/jtag ones are available.
2011-03-02 12:46 <wpwrak> kyak: (serial) here's the competition :) http://www.almesberger.net/misc/ben/idbg-v2-install.jpg
2011-03-02 12:48 <wpwrak> kyak: but an ftdi may indeed be easier to handle in this case, even though the company is unpleasant
2011-03-02 12:55 <kyak> wpwrak: okay :) thanks for information
2011-03-02 15:01 <kristianpaul> wpwrak: what i need activate for kernel debug/console by serial port. my laptop have an onboard serial port,so i was thiking in wiring it with the nanonote so i can get fun with linux someday
2011-03-02 15:07 <wpwrak> the console is already activated. just connect the 3.3V-compatible uart and you're good.
2011-03-02 15:08 <wpwrak> kristianpaul: btw, the idea of reusing the jtag board sounds quite good. this may be an easier first step than messing with the laptop.
2011-03-02 15:13 <kristianpaul> ok, so i need solder jtag pads :-)
2011-03-02 15:15 <wpwrak> in the ben, yes
2011-03-02 15:15 <kristianpaul> sure ;)
2011-03-02 15:17 <wpwrak> nice .. i now have a pretty fast spectrum analyzer for the usrp2 that does exactly what _I_ want ;-) that's a relief after the day of pain
2011-03-02 15:17 <kristianpaul> ubuntu pain? ;)
2011-03-02 15:17 <kristianpaul> i was told gnuradio works prety well in fedora
2011-03-02 15:17 <kristianpaul> oh, i dint noticed the _I_
2011-03-02 15:18 <wpwrak> well, it all began with me trying to upgrade ubuntu in order to resolve that jikes dependency. i looked at their download site and found "natty". not realizing that this was only alpha, i installed it. things went downhill from there ...
2011-03-02 15:19 <wpwrak> (fedora) and i'm not going to switch distributions like that ;-))
2011-03-02 15:20 <kristianpaul> no no, just saying :-)
2011-03-02 15:22 <wpwrak> yesterday, i tried to 1) reinstall some packages to see if it was just some dependency mishap, 2) examine where usrp2_fft.py segfaulted, 3) disable DRI in my X (it segfaulted in DRI), 4) look for alternative spectrum analyzer implementations and try to make them run, and finally, after all the rest failed, 5) started writing my own.
2011-03-02 15:27 <kristianpaul> what is your  current spectrum analyzer implementation?
2011-03-02 15:27 <kristianpaul> oh, writing :D
2011-03-02 15:28 <wpwrak> nice .. does about 60 fps :)
2011-03-02 15:29 <wpwrak> 80% cpu, single-threaded. i should at least dual-thread it.
2011-03-02 21:41 <tuxbrain> xiangfu: you have become an Asian Qi Hardware distributor/reseller? if so great :) http://item.taobao.com/item.htm?id=3661632158
2011-03-02 22:17 <tuxbrain> wpwrak: just suggestion but have you saw this http://www.varesano.net/projects/hardware/Femtoduino, is CCBySA, is in KiCad, is small , is cheap.... maybe it can be a replacement on UART? more power more versatility and it can also act as our proposals of SPI/UART translator, but more things in addition
2011-03-02 22:40 <wpwrak> tuxbrain: yeah, looks nice. you can play with this one, too :) UART is more proof of concept than anything else. and it's still much smaller ;-))
2011-03-02 22:41 <wpwrak> tuxbrain: from the software side, they should be almost the same. so you can apply things i do for uart (avrdude and such) to the femtoduino as well
2011-03-02 22:43 <tuxbrain> wpwrak: the problem is that is not aviable yet :), so to play with it I have to produce it.... let's play first with his big brother UNO
2011-03-02 22:44 <tuxbrain> that's the cool thing on the atmega family, once you have the soft for one, you barelly have the soft for all
2011-03-02 22:47 <tuxbrain> I will have a busy week , so my time to play with ardunote will be barelly nothing, I hope next week I can arrange a hacking session to finish the base system.
2011-03-02 22:50 <wpwrak> tuxbrain: will you go to the pcb fab tomorrow ?
2011-03-02 22:50 <tuxbrain> no they will sendme the pcbs to home
2011-03-02 22:51 <tuxbrain> They ignore my visiti proposal :(
2011-03-02 22:51 <tuxbrain> visit
2011-03-02 22:51 <tuxbrain> I suppose they will arrive by the end of the week
2011-03-02 22:55 <tuxbrain> well time to rest
