Jan 22 06:21:06 <[g2]> ~ugt
Jan 22 06:21:12 <purl> rumour has it, ugt is Universial Greeting Time. Created in #mipslinux, it is a rule that states that whenever somebody enters an IRC channel it is always morning, and it is always late when the person leaves. The local time of any other people in the channel, including the greeter, is irrelevant.
Jan 22 06:21:57 <lennert> erik mouw always says 'gug', 'generalised utc greeting'
Jan 22 06:23:56 <[g2]> ahh
Jan 22 06:24:06 <[g2]> I see that in #netfilter all the time
Jan 22 06:24:22 <lennert> right
Jan 22 06:24:24 <AchiestDragon> hi  , seems to work also :)
Jan 22 06:24:29 <[g2]> heh
Jan 22 06:24:37 <[g2]> now I'll know what it means
Jan 22 06:46:29 <lennert> ka6sox: is there any way to specify in the .ucf file that a pin should be inverted?
Jan 22 06:58:58 <lennert> ka6sox: or a pullup/pulldown?  in what doc file can i find this stuff?
Jan 22 07:03:11 <vmaster> it's about 2 hours too early for ka6sox
Jan 22 08:47:07 <ka6sox> lennert, yes
Jan 22 08:47:19 <ka6sox> and Vmaster is right.
Jan 22 08:48:22 <ka6sox> oh....Morning
Jan 22 08:48:48 <lennert> ka6sox: ok, so how do i do that? :)
Jan 22 08:49:45 <lennert> ka6sox: as to the fm modulator, i'm cleaning it up and checking it in now
Jan 22 08:50:22 <ka6sox> lennert, thansk
Jan 22 08:50:59 <ka6sox> I'm diggin up the one where I had to define it as inverted and defined with pullups.
Jan 22 08:51:32 <lennert> i want pin X to be pulled up iff it's not referenced anywhere in the top entity
Jan 22 08:52:30 <ka6sox> ucf isn't that smart.
Jan 22 08:52:49 <lennert> silly ucf
Jan 22 08:52:57 <ka6sox> :)
Jan 22 08:53:01 <lennert> the 'default' pullup/pulldown params are set in the .ut file
Jan 22 08:53:16 <lennert> but that's not good enough for me, i want to choose pullup/pulldown on a per-pin basis
Jan 22 08:53:19 <lennert> :)
Jan 22 08:53:28 <ka6sox> the UCF does do that.
Jan 22 08:53:39 * lennert loves his fluke 179, btw
Jan 22 08:53:52 <ka6sox> but the UCF is independent of any Entity declarations.
Jan 22 08:54:02 <ka6sox> Universal Constraint File
Jan 22 08:54:05 <lennert> well, ucf sets location/io standard/drive strength/slew rate
Jan 22 08:54:11 <lennert> which is what i use it for
Jan 22 08:54:22 <lennert> but i want to be able to name pins that i don't use
Jan 22 08:54:33 <lennert> (so that if i do start using them in the top entity, they'll use the right pins)
Jan 22 08:54:41 <lennert> and i want to set default direction/pullup/pulldown
Jan 22 08:54:48 <lennert> (so that if i don't use a pin, it'll be set to the right level)
Jan 22 08:55:01 <ka6sox> I've always had to comment and uncomment pins depending on what was going on in the vhd files.
Jan 22 08:55:48 <lennert> i hate that
Jan 22 08:57:25 <ka6sox> its not fun but its the way :(
Jan 22 08:57:43 <ka6sox> lemme sound revelie here....
Jan 22 08:57:56 <lennert> iow xilinx sucks
Jan 22 08:58:07 <ka6sox> I need to wakeup the troops.
Jan 22 08:58:21 <lennert> well, you _can_ add unused pins to the ucf, you just have to tell some tool (map?) to ignore unused constraints
Jan 22 09:00:42 <ka6sox> the docs have been clear as mud on that point
Jan 22 09:00:52 <lennert> most xilinx docs are clear as mud
Jan 22 09:01:01 <lennert> i spent days getting the stupid systemace to work
Jan 22 09:01:15 <lennert> and it turned out that it was much much simpler than the docs wanted you to believe
Jan 22 09:03:38 <velinp> ~seen ka6sox
Jan 22 09:03:41 <ka6sox> like I said...clear as mud
Jan 22 09:03:42 <purl> ka6sox is currently on #openjtag. Has said a total of 30 messages. Is idling for 2m 59s, last said: 'the docs have been clear as mud on that point'.
Jan 22 09:04:03 <ka6sox> coffee...beb
Jan 22 09:04:26 <AchiestDragon> hmm coffee ,,, brb
Jan 22 09:06:37 <ka6sox> back...with Joe
Jan 22 09:06:49 <ka6sox> morning velinp
Jan 22 09:07:04 <velinp> hi; Joe your boy?
Jan 22 09:07:16 <ka6sox> Joe is slang for Coffee
Jan 22 09:07:45 <velinp> sorry; didn't know that; good to see wendy and bob in good health now
Jan 22 09:07:54 <ka6sox> I'm glad too.
Jan 22 09:08:21 <ka6sox> is Velnas beating the hard drive to death yet?
Jan 22 09:08:41 <velinp> that was yesterday; it's now uploading as mad; 
Jan 22 09:09:37 <ka6sox> I should check the status on buildd.net and see if it shows Bob building
Jan 22 09:09:56 <velinp> previous session, too  (because i had to reset it and misled you into a reboot of bob; sorry); bob: libcrypto++_5.2.1c2a-2
Jan 22 09:10:32 <ka6sox> bob acutally was idle for 2 weeks
Jan 22 09:10:48 <ka6sox> everyone thought that he was doing something but he was not
Jan 22 09:10:55 <ka6sox> the reboot "fixed" it
Jan 22 09:11:30 <velinp> that's good; want to forward wouter mail?
Jan 22 09:11:41 <velinp> s/wouter/wouter's/
Jan 22 09:11:41 <purl> velinp meant: that's good; want to forward wouter's mail?
Jan 22 09:11:49 <ka6sox> do you have one?
Jan 22 09:11:53 <ka6sox> ya please do
Jan 22 09:12:52 <ka6sox> when wendy is done we will have the correct libboost for monotone in the db
Jan 22 09:13:16 <ka6sox> lennert: somebody needs to write a Xilinx Doc interpreter.
Jan 22 09:13:31 <lennert> ka6sox: rewriting the xilinx docs would be easier ;)
Jan 22 09:13:41 <ka6sox> true
Jan 22 09:14:15 <ka6sox> when I was first starting I would use the little light bulb examples.
Jan 22 09:14:31 <ka6sox> got my systemACE but havent' installed it.
Jan 22 09:15:24 <lennert> it came with my xupv2p board ;)
Jan 22 09:15:35 <lennert> some idiot soldered it on before they sent it to me
Jan 22 09:17:14 <lennert> http://svn.wantstofly.org/vhdl/template_xupv2p/ has the necessary bits and pieces to go from .vhd to .ace all from the linux command line
Jan 22 09:17:20 <lennert> you do need an ISE license installed, though
Jan 22 09:17:29 <lennert> (for the xc2vp30)
Jan 22 09:17:41 <lennert> works quite nicely here with the compactflash
Jan 22 09:17:47 <ka6sox> I haven't had time to install the SDK yet
Jan 22 09:20:31 <ka6sox> RL keeps getting in the way
Jan 22 09:20:35 <lennert> the fluke has AC frequency measurement, and the fm modulator does indeed produce the desired frequencies
Jan 22 09:20:41 <lennert> ka6sox: tell RL to wait a few days ;)
Jan 22 09:20:54 <ka6sox> okay...I'll do that!
Jan 22 09:21:10 <lennert> ;-)
Jan 22 09:21:13 <ka6sox> maybe when I'm in Hawaii
Jan 22 09:22:35 <lennert> ka6sox: how do i sign-extend something in vhdl?
Jan 22 09:23:15 <ka6sox> never done it.
Jan 22 09:23:29 <lennert> i'll just replicate the MSB
Jan 22 09:23:29 <ka6sox> unless I use a sign bit (separate register)
Jan 22 09:23:45 <lennert> blah(7) & blah(7) & blah(7) & blah(7) & blah(7 downto 0)
Jan 22 09:24:10 <ka6sox> yep.
Jan 22 09:24:49 <ka6sox> I told him that the discussion about build machines for armeb was best done in #debonaras.
Jan 22 09:24:55 <lennert> yeah
Jan 22 09:24:58 <lennert> it's better there
Jan 22 09:26:44 <ka6sox> are you still using the webpack at all?
Jan 22 09:28:37 <lennert> nope
Jan 22 09:28:43 <lennert> just ise now
Jan 22 09:28:50 <lennert> i borrowed my s3 board to a friend
Jan 22 09:28:57 <lennert> as the xupv2p works fine now
Jan 22 09:29:04 <ka6sox> ya.
Jan 22 09:30:17 <vmaster> heh, gotta love xilinx - ise 8.1i is about a month now, and the first service pack has ~100mb
Jan 22 09:31:03 <ka6sox> I saw that :P
Jan 22 09:32:06 <lennert> latest i have is 7.1i
Jan 22 09:32:46 <ka6sox> mine is still in the box.
Jan 22 09:33:08 <ka6sox> time to roust the munchkin.
Jan 22 09:42:00 <ka6sox> munchkin rousted
Jan 22 09:55:44 <vmaster> as far as i know 8.1i has a native gui for linux
Jan 22 09:56:03 <vmaster> they finally got rid of that wind/u nonsense
Jan 22 09:57:20 <lennert> the wind/u name is so corny
Jan 22 09:57:41 <lennert> i won't voluntarily go back to using the gui any time soon
Jan 22 09:57:48 <lennert> even if they rewrite it a million times
Jan 22 10:02:22 <vmaster> heh, well, i prefer an ide for development work - helps me find where i put my stuff
Jan 22 10:02:48 <ka6sox> me too
Jan 22 10:02:58 <ka6sox> especially large projects
Jan 22 10:03:17 <ka6sox> back in a few hours (family going for an outing)
Jan 22 10:03:54 <vmaster> have fun
Jan 22 10:06:59 <lennert> i just can't work with IDEs
Jan 22 10:07:08 <lennert> vi + make are my tools of choice
Jan 22 10:07:19 <lennert> and grep if i get seriously lost
Jan 22 10:07:43 <ka6sox> "real programmers don't use ide's????"
Jan 22 10:08:10 <lennert> dunno, i'm only a fake programmer :)
Jan 22 10:09:56 <ka6sox> makes 2 of us
Jan 22 10:24:00 <AchiestDragon> grrr vi ,, dont like ide's ether but kate is a cool editor for coding with 
Jan 22 10:29:24 <lennert> wish i had a scope
Jan 22 10:29:27 <lennert> ka6sox: you got a scope?
Jan 22 10:31:22 <lennert> damn, he's gone
Jan 22 10:31:31 <lennert> anyone else here with a scope that has the xupv2p board?
Jan 22 11:02:53 * [g2] has neither
Jan 22 11:51:20 <lennert> ka6sox: i have the fm modulator mostly checked in, see http://svn.wantstofly.org/vhdl/dsp/
Jan 22 11:51:58 <lennert> ka6sox: for some reason it's very hissy, not sure yet why
Jan 22 11:52:13 <lennert> ka6sox: it used to work okay, i think i botched something in the cleanup
Jan 22 11:53:05 <lennert> uhm
Jan 22 11:53:14 <lennert> maybe because i have MSB/LSB bits in the wrong order :P
Jan 22 11:55:36 <lennert> at least for the 'red' pins
Jan 22 12:08:58 <lennert> sounds much better now
Jan 22 12:22:10 <AchiestDragon> ka6sox: ping 
Jan 22 12:41:22 <AchiestDragon> ka6sox: http://www.whipy.demon.co.uk/22012006.zip  ,  latest schematics and pcb artwork ,,just its config , voltage regs and smothing caps to do now 
Jan 22 14:22:49 <ka6sox> AchiestDragon, thanks
Jan 22 14:33:15 <lennert> ka6sox: you're back!
Jan 22 14:33:56 <ka6sox> yes..bbqing now
Jan 22 14:34:09 <lennert> ka6sox: did you see my fm link?
Jan 22 14:34:23 <ka6sox> yes did you correct the problem?
Jan 22 14:34:27 <ka6sox> so should I pull now?
Jan 22 14:36:58 <lennert> the distortion problem is partially solved :-/
Jan 22 14:37:04 <lennert> there's still some noise
Jan 22 14:37:10 <lennert> but it might just be my 'antenna'
Jan 22 14:37:17 <lennert> so yeah, you can pull now
Jan 22 14:37:28 <lennert> (or just browse via http)
Jan 22 14:52:26 <lennert> maybe you can see what is the problem
Jan 22 15:08:32 <ka6sox> lennert, thanks...browsing
Jan 22 15:08:50 <lennert> ka6sox: have fun ;-)
Jan 22 15:09:02 <lennert> ka6sox: thanks for having a look
Jan 22 15:09:23 <ka6sox> what machine did you build this for?
Jan 22 15:09:30 <lennert> xupv2p
Jan 22 15:09:44 <lennert> the digilent xc2vp30 board
Jan 22 15:09:51 <ka6sox> k
Jan 22 15:09:58 <lennert> so you should be able to run it
Jan 22 15:10:15 <lennert> just hook up a dipole antenna to {red, red ground} on the vga connector
Jan 22 15:14:24 <ka6sox> okay I can do that
Jan 22 15:19:37 <sinclair73de> hi, after upgrading my Linksys NSLU2-ram to 128MB it seems to be dead. i can switch in on, but only the power led is on. nothing on the serial port. any idea before resolder the original rams? a jtag adapter is available.
Jan 22 15:21:16 <lennert> sinclair73de: i think you'll need a new version of redboot... :-/
Jan 22 15:21:55 <NAiL> won't redboot boot with too much ram? I though it'd just not see the extra ram?
Jan 22 15:22:25 <NAiL> (considering I'm gonna fatslug a slug tomorrow, it would be nice to know ;)
Jan 22 15:22:58 <lennert> i'm not very sure how the memory controller on the xsc2 works
Jan 22 15:23:11 <lennert> i _think_ you have to configure a rows/sec refresh rate
Jan 22 15:23:16 <lennert> (but not sure..)
Jan 22 15:24:43 <AwayNAiL> off to debianize another slug
Jan 22 15:33:59 <sinclair73de> NAil: i think this too...
Jan 22 18:09:06 <[g2]> lennert I think it depends on which chips are used in the fattening
Jan 22 18:09:58 <[g2]> I think if you switch from 8M8 to 16M8 the old RedBoot works, but you just don't see the extra memory
Jan 22 18:10:57 <[g2]> switch to 128MB probably needs to have the memory controller configured differently
Jan 22 18:11:09 <[g2]> ok... that was probably 8M16 to 8M16
Jan 22 18:11:14 <[g2]> doh!
Jan 22 18:11:19 <[g2]> 8M16 to 16M16
Jan 22 18:12:33 * [g2] pick up magnifier
Jan 22 18:13:46 <[g2]> roger
Jan 22 18:13:57 <[g2]> 16M16 is the 64MB config
Jan 22 18:14:08 <[g2]> 8M16 is the 32MB config
Jan 22 18:15:10 <[g2]> so depending on whether he doubled stacked 16M16s or went to 32M16s wouild determine his memory config
Jan 22 18:15:24 <[g2]> hopefully it's 4 8M16s :)
Jan 22 18:15:28 <[g2]> per side
Jan 22 18:21:52 <AchiestDragon> ka6sox: ping
Jan 22 18:23:00 <AchiestDragon> seen a potential problem with ep1220 's  interface  
Jan 22 18:24:24 <AchiestDragon> its got a nice onboard local regulator for powering the jtag vcc line , but  if trying to test or program most fpga or cpld devices there is a problem 
Jan 22 18:26:13 <AchiestDragon> the jtag vcc is the i/o vcc of the device beeing programed , so there is no support for actualy powering the device core logic , so guess that would be a problem , although  
Jan 22 18:27:09 <AchiestDragon> i am not shure if the core needs to be powered in order to run a boundry scan using the jtag ? 
Jan 22 18:29:01 <AchiestDragon> it should only affect its opperation where the board/device under test is getting its power via the jtag and is otherwise unpowered
Jan 22 18:35:37 <AchiestDragon> there could be another potential problem in driving the vcc via jtag , that is load , if the  circut beeing tested has a lot of logic also using the same onboard vcc source then the regulator we are using will overload 
Jan 22 18:36:05 <AchiestDragon> and ether burn out or brown out 
Jan 22 18:36:52 <AchiestDragon> and we only got about 500ma to 1A capacaty on the jtag cable 
Jan 22 18:39:03 <AchiestDragon> so hucking up the jtag to test a device on a unpowered p4 motherboard for example is out  
Jan 22 19:00:41 <tom___> howdy
Jan 22 19:12:10 <[g2]> ping tom___ ping
Jan 22 19:12:39 <[g2]> that's crazy
Jan 22 19:25:29 <AchiestDragon> disregard last comment , it dosent drive the jtag vcc 
Jan 22 19:31:59 <AchiestDragon> need a break from it , getting eyestrain 
Jan 22 20:16:43 <ka6sox> AchiestDragon, take a break....you deserve it.
Jan 22 21:23:04 <ka6sox> Tiersten: I'm going to make the switch to mediawiki for openjtag.
