2010-12-08 05:07 <wolfspraul> roh: great mail! :-)
2010-12-08 07:21 <kristianpaul> indeed
2010-12-08 07:21 <kristianpaul> nice mails to read this morning :)
2010-12-08 08:10 <wpwrak_> finally some action on the list ;-)
2010-12-08 08:11 <lekernel_> hahaha
2010-12-08 09:11 <qi-bot> [commit] kyak: qstardict: initial port http://qi-hw.com/p/openwrt-packages/fa4bfac
2010-12-08 09:54 <kristianpaul> wpwrak_: i need the counter if i'm planning to sync the shifted register agains the Xbusrt SoC i need at leasta  clk for the data
2010-12-08 09:55 <wolfspra1l> andres-calderon: hi Andres!
2010-12-08 09:55 <wolfspra1l> we got the 30 Aptina sensors in stock now
2010-12-08 09:55 <kristianpaul> andres-calderon: hola :)
2010-12-08 09:55 <andres-calderon> nice!
2010-12-08 09:56 <andres-calderon> kristianpaul: hola
2010-12-08 09:58 <andres-calderon> wolfspra1l:  Almost has been finished the  Xué's schematic review.
2010-12-08 09:59 <wolfspra1l> great
2010-12-08 10:00 <wolfspra1l> I am super busy on the Milkymist One RC2 run, testing
2010-12-08 10:00 <wolfspra1l> all looks good
2010-12-08 10:00 <wolfspra1l> we are discussing the goals for the Xue run, everything 100% KiCad process etc.
2010-12-08 10:00 <wolfspra1l> for the Milkymist One RC2 run, it looks like 36 or 37 boards out of 40 are 100% fully tested and pass
2010-12-08 10:00 <wolfspra1l> still working :-)
2010-12-08 10:01 <andres-calderon> Nice, Nelson is keen to buy one.
2010-12-08 10:01 <wolfspra1l> yes
2010-12-08 10:03 <andres-calderon> How much cost the MM1?
2010-12-08 10:03 <wolfspra1l> you mean for sale? 350 USD
2010-12-08 10:03 <wolfspra1l> that includes power adapter and jtag-serial board (which we don't have yet, working on it)
2010-12-08 10:04 <andres-calderon> yes, for sale
2010-12-08 10:04 <wolfspra1l> plus shipping
2010-12-08 10:07 <andres-calderon> When will there de MM1 in the news? Linuxfodevices, engadget, etc. ..
2010-12-08 10:07 <wolfspra1l> good question
2010-12-08 10:08 <wolfspra1l> in my opinion, we should first add a case and turn it into a proper product
2010-12-08 10:08 <wolfspra1l> even if it has no FCC/CE certification, but then it may have to be a kit people need to assemble themselves
2010-12-08 10:08 <wolfspra1l> better would be a 'real' product of course, including fcc/ce
2010-12-08 10:08 <andres-calderon> http://www.xilinx.com/products/devkits/EK-S6-SP605-G.htm
2010-12-08 10:08 <wolfspra1l> then I would say that's at least 3 months out
2010-12-08 10:09 <andres-calderon> 350 USD will be a good price.
2010-12-08 10:09 <kristianpaul> remenber M1 is a VJ Station
2010-12-08 10:09 <wolfspra1l> andres-calderon: once it has a case it will be 499 USD
2010-12-08 10:10 <wolfspra1l> and once it's there, we will drive it down again, 399 USD, etc.
2010-12-08 10:10 <wolfspra1l> but that's a lot of hard work
2010-12-08 10:10 <wolfspra1l> step by step
2010-12-08 10:10 <wolfspra1l> we are not even done testing the rc2 run yet
2010-12-08 10:10 <wolfspra1l> then we need to go full-power on the jtag-serial daughterboard
2010-12-08 10:10 <wolfspra1l> then the case
2010-12-08 10:11 <wolfspra1l> that's a nice development board, but I really don't compare with such boards at all
2010-12-08 10:11 <wolfspra1l> we are working on a product, including software, tools, case, certification, etc.
2010-12-08 10:11 <andres-calderon> wolfspra1l, I think some if it will do. At least compared to  development boards the price is good.
2010-12-08 10:12 <wolfspra1l> yes, and I will try to drive the price down
2010-12-08 10:12 <wolfspra1l> I always feel technology is and must be inherently democratic, power to the people
2010-12-08 10:12 <wolfspra1l> so I'll squeeze out every USD, without compromising the freedom aspect of course
2010-12-08 10:12 <wolfspra1l> even if nobody cares, remember that those avnet boards are subsidized under Xilinx marketing budget
2010-12-08 10:13 <wolfspra1l> when the spartan-7 comes out, they stop selling this one. these are boards to spread their technology in the marketplace. nothing wrong with that, but the direction (and life expectancy) of such a board is very different from our product.
2010-12-08 10:14 <wolfspra1l> but yeah, if we can even beat them on price, that's cool!
2010-12-08 10:14 <wolfspra1l> :-)
2010-12-08 10:14 <wolfspra1l> but not my #1 focus
2010-12-08 10:14 <andres-calderon> wolfspra1l: avnet, digilent, huhorizons board are subsidized  by xilinx, ISSI, Linear, etc..
2010-12-08 10:14 <wolfspra1l> are you asking me or telling me?
2010-12-08 10:14 <wolfspra1l> I don't care. Even if Xilinx gives you 100 USD cash for every devboard from them, so what?
2010-12-08 10:15 <wolfspra1l> then get a lot of them :-)
2010-12-08 10:15 <wolfspra1l> I work on a product.
2010-12-08 10:15 <andres-calderon> just telling... the avnet, digilent, huhorizons boards are full of propaganda of the manufacturers of the chips.
2010-12-08 10:15 <wolfspra1l> of course
2010-12-08 10:15 <wolfspra1l> it's a marketing tool
2010-12-08 10:16 <wolfspra1l> so anyway
2010-12-08 10:16 <wolfspra1l> I am working on a great product.
2010-12-08 10:16 <wolfspra1l> long way :-)
2010-12-08 10:38 <xiangfu> kyak: Hi. I want  start create a new openwrt image release tomorrow.
2010-12-08 10:39 <qi-bot> [commit] Xiangfu Liu: remove freedroid http://qi-hw.com/p/openwrt-packages/4ad9ef5
2010-12-08 10:39 <qi-bot> [commit] Xiangfu Liu: remove BROKEN,add --without-mp3 by default http://qi-hw.com/p/openwrt-packages/760fbb1
2010-12-08 10:39 <qi-bot> [commit] Xiangfu Liu: add moc qstardict to config.full_system http://qi-hw.com/p/openwrt-xburst/e9fe7d7
2010-12-08 10:39 <xiangfu> kyak: just base on the last commit of openwrt-xburst[e9fe7d7], openwrt-package[760fbb1].
2010-12-08 10:40 <xiangfu> I will test the image first tomorrow. :)
2010-12-08 10:41 <xiangfu> kyak: need sleep, see you.
2010-12-08 10:41 <wolfspra1l> he must have been sleepy :-)
2010-12-08 10:43 <kristianpaul> oh moc
2010-12-08 10:43 <kristianpaul> lets compile :)
2010-12-08 11:36 <kristianpaul> good now vim automatically help me on indentation :)
2010-12-08 12:43 <viric> hello back
2010-12-08 12:43 <viric> time to learn the halt sequence on openwrt..
2010-12-08 12:43 <viric> (basically, sysvinit)
2010-12-08 12:44 <kristianpaul> good :)
2010-12-08 12:45 <viric> I don't have that solved...
2010-12-08 12:45 <viric> 'halt -fp' powers down, but 'halt' does not power down.
2010-12-08 12:46 <wpwrak_> kristianpaul: (sync) hmm, what form of sync did you have in mind ?
2010-12-08 12:50 <kristianpaul> wpwrak_: simple as posible, i was thinking a clk and data  (4bit), mcu can read when clk go high
2010-12-08 12:50 <kristianpaul> there is also a reset signal from mcu in order to do initialization
2010-12-08 12:52 <wpwrak_> kristianpaul: if you shift into a parallel bits, your SIGE SYNC becomes the CPU data clock
2010-12-08 12:52 <wpwrak_> kristianpaul: now, do you plan to use DMA ? or poll by software ?
2010-12-08 12:52 <kristianpaul> yup :)
2010-12-08 12:52 <kristianpaul> dma dont know how
2010-12-08 12:53 <kristianpaul> pull by sofware for now
2010-12-08 12:53 <kristianpaul> gpio > ram > dump to disk
2010-12-08 12:53 <wpwrak_> then you could have a "data phase" signal. toggle it whenever you update the output, i.e., on each SYNC.
2010-12-08 12:54 <wpwrak_> for DMA, you would need a proper DMA request signal. you'd also want to go 8 bit, to avoid wasting half your memory/bandwidth, because DMA only has 8/16/32 bit size.
2010-12-08 12:55 <kristianpaul> 8 bits easy, just other 4 wires grounded
2010-12-08 12:56 <kristianpaul> or you meant provide full 8 bit data per sample?
2010-12-08 12:57 <wpwrak_> the latter :)
2010-12-08 12:58 <wpwrak_> still easy: you either make the shifter 8 bits wide and divide incoming SYNC by two, or add a multiplexer
2010-12-08 12:58 <kristianpaul> ah yes
2010-12-08 12:59 <kristianpaul> actually i need 16bits but QIQIQIQI not QQIIQQIIQQIIQQII
2010-12-08 12:59 <kristianpaul> well that was the data format the guy from sdr-gps ask me for
2010-12-08 12:59 <wpwrak_> do you have enough I/Os for a 16 bit wide interface ?
2010-12-08 12:59 <kristianpaul> sure
2010-12-08 13:00 <kristianpaul> well in SIE
2010-12-08 13:00 <kristianpaul> but not in Ben if i think in long term
2010-12-08 13:00 <wpwrak_> for the  ben, you need something radically different anwyway
2010-12-08 13:03 <kristianpaul> reading SD espefication i founded GPS like a posible device for SDIO
2010-12-08 13:04 <kristianpaul> but clasical GPS with ASIC not for doing SDR of course
2010-12-08 13:04 <wpwrak_> but how would the 16 bits be organized ? if the input is  sI0 mI0 sQ0 mQ0 sI1 mI1 sQ1 mQ1 sI2 mI2 sQ2 mQ2 sI3 mI3 sQ3 mQ3  what would be the 16 bit output ?
2010-12-08 13:05 <wpwrak_> (sdio) you could just do a bunk data transfer for SDR
2010-12-08 13:06 <wpwrak_> but that's something to worry about in the distant future :)
2010-12-08 13:06 <kristianpaul> sure sure
2010-12-08 13:06 <wpwrak_> by then you'll also be more confident at making interfaces with the FPGA :)
2010-12-08 13:06 <kristianpaul> (16 bit output) sIx and mQx in theory are not needed
2010-12-08 13:06 <kristianpaul> hehe confidence yes i must improve
2010-12-08 13:07 <wpwrak_> (throw away half the data) really ?
2010-12-08 13:07 <kristianpaul> well..
2010-12-08 13:07 <kristianpaul> i saw a sofware that does it
2010-12-08 13:07 <kristianpaul> for other dongle
2010-12-08 13:08 <kristianpaul> but from 2 bit data , just 2 posible values from 4 are posible
2010-12-08 13:08 <wpwrak_> hmm. not 3 ?
2010-12-08 13:08 <kristianpaul> well if 0 is ignore ;)
2010-12-08 13:08 <wpwrak_> -1, 0, +1
2010-12-08 13:08 <kristianpaul> i need to ask more about 0
2010-12-08 13:09 <kristianpaul> not sure yet
2010-12-08 13:09 <wpwrak_> so you would send a -1 or +1 instead of a 0, and have a "i sent an offset" bit you'd use to modify future bits ?
2010-12-08 13:09 <kristianpaul> anway lets take first the sample and lookg for how many 0 there
2010-12-08 13:10 <kristianpaul> s/lookg/look
2010-12-08 13:10 <wpwrak_> my guess would be between 33 and 50% ;-) depends a bit on what the mysterious sign in the case of 0 really means
2010-12-08 13:11 <kristianpaul> ( 0 really means) i still dont understand
2010-12-08 13:11 <kristianpaul> or my brain just focused on -1 and +1 when reading book theory
2010-12-08 13:11 <kristianpaul> i shoudl read again for sure later
2010-12-08 13:13 <viric> I can't find what openwrt does special at shutdown
2010-12-08 13:14 <kristianpaul> special?
2010-12-08 13:14 <wpwrak_> well, you could take a reference signal and see what happens if you eliminate all the 0s.
2010-12-08 13:14 <kristianpaul> wpwrak_: actually i need do some FFT on signal and i should get something interesting graph
2010-12-08 13:14 <viric> kristianpaul: I see from inittab that it calls simply all the 'K*' rc scripts
2010-12-08 13:15 <viric> and one of those scripts has to run the power down, I think.
2010-12-08 13:15 <kristianpaul> sure is no that job of trigerhappy?
2010-12-08 13:16 <viric> I don't know what powers off the nanonote
2010-12-08 13:16 <kristianpaul> KEY_POWER       1       /sbin/poweroff
2010-12-08 13:16 <viric> oh
2010-12-08 13:16 <viric> what is that?
2010-12-08 13:16 <kristianpaul>                              already check this^ ?
2010-12-08 13:16 <viric> and what calls poweroff in the shutdown sequence?
2010-12-08 13:17 <viric> I know the poweroff command of sysvinit
2010-12-08 13:18 <kristianpaul> /sbin/ poweroff source code deserver a look
2010-12-08 13:18 <kristianpaul> you may get surpriced
2010-12-08 13:20 <kristianpaul> sysvinit you're riht
2010-12-08 13:20 <kristianpaul> right*
2010-12-08 13:21 <viric> I have /sbin/poweroff
2010-12-08 13:22 <viric> but I expect the system to do a proper shutdown and then power off, when I type 'halt'
2010-12-08 13:22 <viric> and in my system it does not happne :)
2010-12-08 13:22 <viric> it properly shuts down, but it does not power off.
2010-12-08 13:29 <wpwrak_> viric: just sync; sync; /sbin/halt -fp and be happy ? :)
2010-12-08 13:30 <kristianpaul> yay :)
2010-12-08 13:30 <wpwrak_> all the long ritualized suicide a "regular" halt performs is kinda dubious to me anyway
2010-12-08 13:32 <kristianpaul> wpwrak_: are you in favor of massive suiciede? no layers no advice
2010-12-08 13:39 <wpwrak_> it's a battery powered device. it can die "uncleanly" any moment. if you tell me your systems NEEDS an elaborate shutdown process, i can show you a system that's inherently flawed ;-)
2010-12-08 13:48 <viric> wpwrak_: I know that is your way :)
2010-12-08 13:48 <viric> wpwrak_: it's nice if openssh kills properly the active ssh conections...
2010-12-08 13:49 <viric> wpwrak_: if wtmp gets properly written...
2010-12-08 13:49 <viric> wpwrak_: if the filesystems get 'umounted' (sync; sync; is not the same as umounting :)
2010-12-08 13:51 <wpwrak_> viric: think of "sync" as a non-blocking "umount" that always succeeds ;-)
2010-12-08 13:51 <wpwrak_> i.e., precisely what you want when in a hurry to shut down :)
2010-12-08 13:54 <viric> it may work in the context where you know that there are no processes writing to the filesystem at that time :)
2010-12-08 14:02 <wpwrak_> if you have on-going write activity, things don't look too good anyway ;-) and hey, isn't that what they sold us journaling for ? ;-)
2010-12-08 14:09 <qi-bot> [commit] kyak: qstardict: adjust main window to look nicer http://qi-hw.com/p/openwrt-packages/c97f249
2010-12-08 14:17 <kristianpaul> ah i finally found a use for the counter,
2010-12-08 14:17 <kristianpaul> debugging led :)
2010-12-08 14:17 <kristianpaul> he
2010-12-08 14:17 <wpwrak_> ;-)
2010-12-08 14:23 <steve|m> wpwrak_: oh, you're hanging out here.. the world is so small.. I discovered m8cutils today
2010-12-08 14:23 <steve|m> for hacking this device: http://wiki.steve-m.de/doku.php/epa_basis_reader
2010-12-08 14:24 <wpwrak_> steve|m: wow, digging up old stuff :)
2010-12-08 14:28 <steve|m> heh, indeed.. I tried my luck with the wadsp today, but didn't suceed.. "Txresinit deadline missed"
2010-12-08 14:31 <steve|m> tomorrow I'll receive the MiniProg1, then I have something to compare.. but your m8cutils might gain interest again, since 400.000 of those devices were given away for free with magazine "ComputerBild"
2010-12-08 14:32 <wpwrak_> wow. the disppearance of those old interfaces may prove to be a bit of a problem, though
2010-12-08 14:34 <wpwrak_> steve|m: did you connect it directly to a serial port on the PC or via a USB-to-serial dongle ? the latter would explain the problem
2010-12-08 14:35 <steve|m> I used the OpenMoko debug board (ft2232), and omitted the 1.5k resistors, since it has already 3.3V levels.. (which might be a problem as well)
2010-12-08 14:37 <wpwrak_> hmm, so you used it as a USB-to-serial dongle ? or did you run m8cprog on the Neo ?
2010-12-08 14:38 <wpwrak_> for resistors, i think you still need the pull-down (R1)
2010-12-08 14:39 <wpwrak_> voltage may be okay
2010-12-08 14:39 <steve|m> wpwrak_: yeah, I used it as a usb serial dongle..
2010-12-08 14:40 <wpwrak_> ah, that wouldn't work. it's too slow.
2010-12-08 14:40 <wpwrak_> the PSoCs have some fairly tight timing
2010-12-08 14:40 <steve|m> ah, okay.. that's why you're even using RT stuff (I wondered already..)
2010-12-08 14:41 <wpwrak_> what you could do is make m8cprog run on the Neo and control GPIOs directly
2010-12-08 14:41 <wpwrak_> similar to http://projects.qi-hardware.com/index.php/p/f32xbase/source/tree/master/f32x
2010-12-08 14:42 <wpwrak_> (that one works on Neo+debug board and Ben)
2010-12-08 14:42 <steve|m> wpwrak_: mh, I have no neo.. but yeah.. I did something like that a few weeks ago with the seagate dockstar (used the GPIOs as logic analyzer), so I have some code lying around
2010-12-08 14:42 <wpwrak_> steve|m: here's the setup with the Neo: http://www.almesberger.net/misc/idbg/
2010-12-08 14:43 <wpwrak_> perfect. then you're all set :)
2010-12-08 14:44 <steve|m> sampling speed was something like 40MHz, so this should be enough :)
2010-12-08 14:45 <wpwrak_> yeah. you'll run circles around the little chip :)
2010-12-08 14:50 <steve|m> but maybe they have the flash-protection enabled.. but they say on their homepage it is upgradable via usb, so it can only be the "external" programmer lock
2010-12-08 14:51 <wpwrak_> if you do a full erase, you also erase the protection
2010-12-08 14:51 <wpwrak_> some of these chips even let you read their content if "protection" is enabled ;-)
2010-12-08 14:51 <qi-bot> [commit] Jiri Brozovsky: Small command line time tracker - openwrt port, patched for better help message. http://qi-hw.com/p/openwrt-packages/d02893d
2010-12-08 14:51 <steve|m> oh, that's good to know.. so just like the AVR with chip erase
2010-12-08 14:52 <steve|m> wpwrak_: good to know!
2010-12-08 15:16 <kristianpaul> wpwrak_: (assign) yes i was wrong about real world asigment wich is done following some definitions in a ucf file in wichs in/out module name correspond
2010-12-08 15:16 <kristianpaul> actually i dont know why i said that :/
2010-12-08 15:17 <wpwrak_> confusion is a phenomenon that is know to occasionally affect people ;-)
2010-12-08 17:02 <bartbes> would running enlightenment on the ben be possible?
2010-12-08 17:34 <viric> I tried 'echo mem > /sys/power/state'
2010-12-08 17:35 <viric> while the screen had no light (due to the inactivity timeout)
2010-12-08 17:35 <viric> and when back (pressing keys) the screen does not light at all
2010-12-08 17:38 <bartbes> hmm, can you manually activate the backlight?
2010-12-08 17:38 <viric> How could I do it?
2010-12-08 17:38 <bartbes> since I forgot how to turn it off, I don't remember how to turn it on either
2010-12-08 17:39 <bartbes> but give me a sec while I power on my ben
2010-12-08 17:39 <viric> :)
2010-12-08 17:39 <viric> thank you
2010-12-08 17:41 <bartbes> i see /sys/class/lcd/gpm940b0-lcd
2010-12-08 17:41 <viric> and?
2010-12-08 17:42 <bartbes> echo 0 > /sys/class/lcd/gpm940b-lcd/lcd_power
2010-12-08 17:43 <bartbes> viric: did it help?
2010-12-08 17:43 <viric> it is for turning on?
2010-12-08 17:43 <bartbes> yes
2010-12-08 17:43 <viric> I have a different lcd :)
2010-12-08 17:43 <bartbes> 1 is off, 0 is on
2010-12-08 17:44 <viric> /sys/class/lcd/ili8960-lcd
2010-12-08 17:44 <bartbes> doesn't it have an lcd_power file?
2010-12-08 17:44 <viric> I wait until it turns off... then I'll suspend.
2010-12-08 17:44 <viric> it has it has.
2010-12-08 17:44 <bartbes> then try writing 0 to it
2010-12-08 17:44 <bartbes> if it doesn't work, try 1
2010-12-08 17:44 <viric> yes
2010-12-08 17:44 <bartbes> it worked for me
2010-12-08 17:44 <bartbes> in fact, there even was a power/wakeup
2010-12-08 17:44 <viric> after sleep?
2010-12-08 17:45 <bartbes> no, in the lcd folder, a file called power/wakeup
2010-12-08 17:45 <viric> there is
2010-12-08 17:45 <viric> what does that mean?
2010-12-08 17:45 <bartbes> if you write.. say.. 1 to it, it should wake it up ;)
2010-12-08 17:45 <bartbes> but hey, I don't know
2010-12-08 17:45 <bartbes> I'm no hw expert by a long shot
2010-12-08 17:46 <viric> ahh..
2010-12-08 17:46 <bartbes> I just like poking around
2010-12-08 17:46 <viric> how much it takes for the lcd to go black on inactivity?
2010-12-08 17:46 <bartbes> you mean how long?
2010-12-08 17:47 <bartbes> I remember something about 15 secs, but I'm probably wrong
2010-12-08 17:47 <bartbes> :P
2010-12-08 17:47 <bartbes> (maybe that was gmu?)
2010-12-08 17:48 <viric> eh?
2010-12-08 17:48 <viric> almost 10 minutes passed here
2010-12-08 17:48 <viric> Oh! Just now.
2010-12-08 17:48 <viric> # echo 1 > wakeup
2010-12-08 17:48 <viric> -bash: echo: write error: Invalid argument
2010-12-08 17:49 <viric> echo 0 or 1 to lcd_power does not help.
2010-12-08 17:49 <viric> 'cat lcd_power' says 4, btw
2010-12-08 17:49 <viric> (after 'echo 1 > lcd_power')
2010-12-08 17:50 <viric> then.. bad thing
2010-12-08 17:50 <viric> does it work for you? making it sleep through ssh when the lcd switched off.
