May 02 10:04:20 <prpplague> [g2]: lo ho
May 02 10:04:32 <prpplague> [g2]: whats cookin?
May 02 10:06:36 <[g2]> hey prpplague !  Lots of stuff
May 02 10:06:56 <[g2]> I've been playing with the Linksys RV series boxen  the 042 and 082
May 02 10:07:20 <prpplague> lovely
May 02 10:07:31 <[g2]> Quite
May 02 10:07:57 * prpplague is trying to put the final touches on a kernel and ramdisk for our new core module
May 02 10:08:30 <[g2]> excellent!
May 02 10:08:50 <prpplague> i can't seem to get everything together
May 02 10:09:11 <prpplague> everytime a do a fresh build i find 2 or 3 more little things to fix
May 02 10:09:18 <prpplague> s/a/i
May 02 10:45:31 <[g2]> wb
May 02 11:14:46 <prpplague> beewoolie: hey hey
May 02 11:15:05 <beewoolie> yo yo
May 02 11:15:24 <beewoolie> building...building...buiding...
May 02 11:15:31 <prpplague> beewoolie: 2.6 patches for lh79520?
May 02 11:15:42 <beewoolie> Oh, yeah.  Let me look at that right now.
May 02 11:27:16 <beewoolie> prpplague: Look at the ftp server...
May 02 11:27:32 <beewoolie> ftp://ftp.buici.com/pub/arm/patch-linux-2.6.11/m14
May 02 11:27:42 <beewoolie> There is an IDE patch and a patch for the 7952x's.
May 02 11:27:59 <beewoolie> You'll be getting a little of the R2 patch, but it shouldn't matter.
May 02 11:28:41 <prpplague> looking
May 02 11:29:31 <prpplague> beewoolie: the ide patch, i assume thats for an ide hd interface?
May 02 11:29:46 <beewoolie> CF.
May 02 11:30:25 <prpplague> ahh
May 02 11:30:38 <prpplague> we aren't using cf so no biggy
May 02 11:31:10 <prpplague> thanks
May 02 11:31:33 * prpplague is having trouble being motivated today
May 02 11:31:36 <beewoolie> I'm hoping that AC gets into the IDE drivers seat.  The current maintainer isn't making things better.
May 02 11:32:20 <beewoolie> "Unmotivated?  Felling a bit tired?  Wishing you have the youthful exuberance you remember feeling just last month?"
May 02 11:32:45 <beewoolie> "Try Xanax" [xanax...xanax...xanax...xanax...]
May 02 11:32:48 <prpplague> beewoolie: hehe, no, its this island life
May 02 11:32:55 <beewoolie> "Try Xanax" [xanax...xanax...xanax...xanax...]
May 02 11:32:59 <prpplague> beewoolie: hehe
May 02 11:33:45 <prpplague> i'm gonna have to work late tonight
May 02 11:34:30 <beewoolie> "Try Xanax" [xanax...xanax...xanax...xanax...]
May 02 11:35:13 <prpplague> beewoolie: hehe, your really a big believer in xanax is see
May 02 11:35:58 <beewoolie> [In a sepulchural voice] xanax...xanax...XANax...XANAX...
May 02 11:36:49 <[g2]> beewoolie, can you peek at something for a moment ?
May 02 11:37:12 <beewoolie> Sure.  xanax...xanax...  What is it?
May 02 11:37:21 <[g2]> http://www.digilentinc.com/info/cerebot.cfm
May 02 11:37:30 <[g2]> FPGA controller ?
May 02 11:38:43 <[g2]> We'd have to load via the UART and get data out vis the UART
May 02 11:39:20 <beewoolie> for JTAG?
May 02 11:39:32 <[g2]> yeah it was a long-shot
May 02 11:39:49 <beewoolie> It's kinda big.  What does it cost?
May 02 11:39:55 <[g2]> $59
May 02 11:41:21 <beewoolie> So, we'd have to bit-bang the JTAG.  It seems like the limiting factor would be bandwidth into and out of the device.  Can be get 12Mib over the serial channels?  I'm skeptical.
May 02 11:41:39 <[g2]> ok.
May 02 11:41:53 <[g2]> I want go get rolling on OpenJTAG
May 02 11:42:25 <beewoolie> I do too.  I spoke with a hardware engineer a couple of weeks ago.  He does a lot of board layout for one of my ex clients.
May 02 11:42:43 <beewoolie> He'd be willing to review a board layout if I brought it to him.
May 02 11:42:58 <[g2]> for OpenJTAG or other stuff ?
May 02 11:43:00 <beewoolie> I thought I might take a whack at the 232 design we'd talked about.
May 02 11:43:11 <beewoolie> It shouldn't be too rough.
May 02 11:43:36 <beewoolie> Either that, or I'd just buy in of the dev kits available and see if I could get it to fly.
May 02 11:44:16 <[g2]> I've got the S3 and USB2 all ready to go
May 02 11:44:22 <[g2]> I just need some FPGA code
May 02 12:23:59 <[g2]> I've got 2 digilnet cables
May 02 19:35:03 * dyoung-web me toos
May 02 19:36:27 <dyoung-web> the 2232 should be whackable in short order.  i drew a q/d schmatic in PCB with the 2232 and 9536 and hit it with autoroute.  its pretty straight forward.
May 02 19:41:39 <ka6sox-office> heh
May 02 19:41:57 <dyoung-web> not pcb, I used the other one.  what was it called again...
May 02 19:42:04 <ka6sox-office> eagle
May 02 19:42:08 <dyoung-web> yeah that one.
May 02 19:43:00 <ka6sox-office> shipping tommorrow morning to me.
May 02 19:44:37 <ka6sox-office> how goes the proggie?
May 02 19:45:31 <dyoung-web> its not.
May 02 19:45:40 <ka6sox-office> ow.
May 02 19:45:56 <dyoung-web> I need to mod that board first.
May 02 19:46:22 <ka6sox-office> the other one too unstable?
May 02 19:46:47 <dyoung-web> no, theres too much crap on it.  I cant get to aux-serial.
May 02 19:48:31 <ka6sox-office> okay
May 02 20:00:56 <beewoolie> Go dyoung.
May 02 20:01:24 <beewoolie> Can you tell me what the 9536 is?
May 02 20:01:27 <dyoung-web> I didnt say it was GOOD.  I basically slapped it down to see how bad it was gonna be.
May 02 20:02:03 <beewoolie> Really, how many parts do we need?  A crystal, one or two chips (I don't know the 9536 number), and some caps and resistors.
May 02 20:02:25 <dyoung-web> The xilinx 9536 is a cpld.  that lets us have a wide range of voltage compatibility.
May 02 20:02:46 <beewoolie> I should be done in a week or so with this milestone.  At that point, I'm going to take a closer look at all of this JTAG stuff.
May 02 20:03:00 <beewoolie> dyoung-web: Excellent.  I didn't remember the part number.
May 02 20:03:31 <beewoolie> What makes you think there is anything else to worry about?  I suppose we need to rationalize the interface headers, but the rest should be handle-able in the FPGA/sw dev phase.
May 02 20:03:39 <dyoung-web> theres really not a whole lot to it.
May 02 20:03:48 <dyoung-web> Nothing else to really worry about.
May 02 20:04:13 <dyoung-web> Was I worried?  I dont remmeber.
May 02 20:04:25 <beewoolie> dyoung-web: Sorry about this.  I need to jet.  If we get a schematic, I can run it by a EE I know who said he'd vet it for me/us.
May 02 20:04:33 <beewoolie> He makes a lot of boards.
May 02 20:04:52 <beewoolie> And I'm serious...
May 02 20:04:54 <beewoolie> ttfn
May 02 20:04:57 <dyoung-web> Cool
May 02 20:29:31 <ka6sox-office> what is beewoolie trying to get done and what is the CPLD for?
May 02 20:29:41 <dyoung-web> the JTAG Dongle
May 02 20:30:19 <dyoung-web> the CPLD is for voltage compatibility.
May 02 20:30:22 <ka6sox-office> oh...somebody has been keeping me kinda busy so I haven't gotten to that...but I do Have a Schemmatic.
May 02 20:30:24 <dyoung-web> and glue logic.
May 02 20:33:43 <dyoung-web> is "splitting" a signal in vhdl as easy as it looks?
May 02 20:34:01 <dyoung-web> foo <= bar; baz <= bar; 
May 02 20:34:02 <dyoung-web> ?
May 02 20:34:05 <ka6sox-office> yes
May 02 20:34:08 <ka6sox-office> correcto
May 02 20:34:48 <dyoung-web> I dont have a HC125 handy; but I do have some SOIC 244's.
May 02 20:34:52 <dyoung-web> HC244's
May 02 20:35:22 <ka6sox-office> okay...I ordered a bunch of HCT125's
May 02 20:35:38 <dyoung-web> I was gonna mod it today though.
May 02 20:35:42 <dyoung-web> so I can work on it tommrow.
May 02 20:36:05 <ka6sox-office> use the '244...it'll work.
May 02 20:36:21 <dyoung-web> is there a major danger in not terminating the extra outputs?
May 02 20:36:32 <ka6sox-office> I used 47k pullups to reduce the drain...
May 02 20:36:50 <ka6sox-office> in HC parts it is always good to ground unused parts.
May 02 20:37:04 <dyoung-web> is 47k too much?
May 02 20:37:17 <ka6sox-office> no
May 02 20:37:17 <dyoung-web> the Xilinx AN says 500-1000 ohm.
May 02 20:37:47 <ka6sox-office> 1k ohm means you draw 5ma when its pulled down.
May 02 20:38:25 <dyoung-web> okay I'll try with 47k on the modded board.
May 02 20:38:30 <ka6sox-office> :)
May 02 20:38:40 <dyoung-web> but I'm not going to gound the extra stuff.
May 02 20:38:46 <dyoung-web> that will take too long on this part.
May 02 20:38:49 <ka6sox-office> yeah.
May 02 20:39:29 <ka6sox-office> I need to go home...how long will yo be there?
May 02 20:39:37 <dyoung-web> not long.
May 02 20:39:40 <ka6sox-office> (its 30 minutes for me to get home)
May 02 20:39:47 <dyoung-web> I'm just about done.
May 02 20:39:47 <ka6sox-office> okay is there something I can help wiht now?
May 02 20:40:15 <dyoung-web> not unless you can tell me where i can salvage a HC125 from.
May 02 20:42:07 <ka6sox-office> um...dunno...haven't seen one swimming by the Islands recently.
