May 27 06:28:36 <[g2]> ep1220, hello
May 27 06:28:55 <[g2]> any luck with Q8 pin 1 ?
May 27 06:29:16 <dyoung-zzzz> The magic pin
May 27 06:29:22 <[g2]> nod.
May 27 06:29:46 <[g2]> dyoung-zzzz, did you see that kitno455 had updated the wiki ?
May 27 06:29:51 <dyoung-zzzz> yes.
May 27 06:30:30 <dyoung-zzzz> based on that ka6sox and I reworked the candidate circuit for the the FT2232 based board.
May 27 06:30:59 <[g2]> so what's the plan there ?
May 27 06:31:16 <dyoung-zzzz> the circuit is clear in my brain.
May 27 06:31:32 <dyoung-zzzz> but dunno how much is laid out in PCB, etc
May 27 06:32:13 <[g2]> wasn't ka6sox planning on posting something ?  Is this the same or different ?
May 27 06:32:43 <[g2]> I've got pcb and geda on the DVD btw
May 27 06:32:55 <dyoung-zzzz> cool.
May 27 06:33:16 <dyoung-zzzz> he was gonna post something. but I dunno the status of that right now.
May 27 06:33:36 <[g2]> well he's been busy and said it would be a little while
May 27 06:33:50 <[g2]> I'm just wondering if his thing is similar or different to your thing
May 27 06:34:03 <dyoung-zzzz> hehe hes been busy with my revenue project.  
May 27 06:34:13 <dyoung-zzzz> his thing is the same thing as my thing.
May 27 06:34:44 <[g2]> your "revenue" project or a "real" project 
May 27 06:34:55 <dyoung-zzzz> now that I've worked with the 95xx abit, i have a much clearer idea of what to do.
May 27 06:35:09 <dyoung-zzzz> "real" project for me, "revenue" project for him.
May 27 06:35:16 <[g2]> nod.
May 27 06:35:22 <[g2]> that's what I thought
May 27 06:35:48 <[g2]> and I certainly don't want to distract him at all from that
May 27 06:35:59 <dyoung-zzzz> Its done now.
May 27 06:36:17 <[g2]> excellent
May 27 06:36:28 <dyoung-zzzz> so on to funner stuff. :-)
May 27 06:37:16 <ep1220> g2: Hi.
May 27 06:37:25 <ep1220> not yet tried Q8/1
May 27 06:37:42 <ep1220> want to find out if and how it is driven, before i hort it :-)
May 27 06:37:51 <ep1220> s/hort/short/
May 27 06:37:53 <[g2]> ep1220, Ok wonderful
May 27 06:38:15 <[g2]> I should be getting 1st article re-worked boards back very soon
May 27 06:38:26 <ep1220> currently adding 3.3V to my 2232 module
May 27 06:38:38 <[g2]> for serial ?
May 27 06:38:46 <[g2]> or JTAG
May 27 06:38:58 <[g2]> JTAG i'm guessing :)
May 27 06:39:01 <ep1220> can be used for both
May 27 06:39:21 <ep1220> the module takes 5V from USB
May 27 06:39:24 <[g2]> OH.... yeah baby !
May 27 06:39:39 <ep1220> the VCCio for ports A and B is on a pin.
May 27 06:39:53 <ep1220> i add a 3.3V regulator and connect to both
May 27 06:41:06 <[g2]> so you'll handle both USB and JTAG via the usb connection back to the host
May 27 06:41:38 <ep1220> WOuld be possible. But I ignore serial at first step
May 27 06:41:45 <[g2]> nod.
May 27 06:42:10 <[g2]> what does the regulator cost ?
May 27 06:42:10 <ep1220> in theory the offical driver should suffice.
May 27 06:42:51 <[g2]> and any idea of how much power it sucks ?
May 27 06:43:02 <ep1220> i#d say 40cents in small quantities. 
May 27 06:43:06 <dyoung-zzzz> we'll need that anyways to power the CPLD.
May 27 06:43:39 <[g2]> I don't think ep1220's solution requires a CPLD
May 27 06:43:57 <dyoung-zzzz> neither does ours, it allows for a wide range of voltages.
May 27 06:44:19 <dyoung-zzzz> if I were talking to only a 3.3V device we could do it with the 2232 only.
May 27 06:44:55 <[g2]> Ok here are my thoughs
May 27 06:45:33 <[g2]> I'll have re-worked boards soon that have the serial header, JTAG header (less AC13) and 64 MB
May 27 06:46:09 <[g2]> So what I'm missing is the serial and JTAG connector parts
May 27 06:46:36 <[g2]> I'd love to build a single solution that does both as ep1220 is describing
May 27 06:46:50 <dyoung-zzzz> yeah, thats the plan.
May 27 06:47:00 <dyoung-zzzz> based on what we had discussed previously.
May 27 06:47:02 <[g2]> ideally, the next batch has AC13 brought out and that connects up also
May 27 06:47:27 <dyoung-zzzz> OR, PortB can be used for a control channel.
May 27 06:47:54 <ep1220> One caveat: the NSLU does not have Hw-handshake on serial
May 27 06:47:54 <dyoung-zzzz> because we have a CPLD in there, it can easily be reconfigured.
May 27 06:48:12 <[g2]> finally, I'm more interested in an initial solution just for the NSLU2 than a generic solution
May 27 06:48:24 <[g2]> for the short-term
May 27 06:48:57 <dyoung-zzzz> I'm not, because if I have a dongle that can be reconfigured based on what my current needs are, I'd rather have that.
May 27 06:49:19 <dyoung-zzzz> and that is what the additional CPLD affords us.
May 27 06:49:34 <[g2]> right it's a volume thing
May 27 06:50:13 <[g2]> and time-to-market ting
May 27 06:50:16 <[g2]> and time-to-market thing
May 27 06:50:52 <dyoung-zzzz> If I'm making a NSLU2 specific thing, its just a 2232 daughterboard with a bunch of wires hanging out of it.
May 27 06:51:28 <[g2]> actually two headers
May 27 06:51:45 <dyoung-zzzz> the nslu2 doesnt have a jtag header. :-)
May 27 06:52:14 <[g2]> the re-work shop will probably have the wire coming out of the box and they could have a header attached
May 27 06:52:56 <[g2]> which mates up to a simple board or different boards (i.e. The compsys connection, and a digilent) or our board
May 27 06:53:48 <[g2]> dyoung-zzzz, My nslu2's will have a jtag header :)
May 27 06:54:21 <dyoung-zzzz> well, mine does too, but thats not exactly gonna be nslu2 specific....
May 27 06:54:51 <[g2]> the cost is next to nothing for me to add it
May 27 06:55:07 <[g2]> and for RMA etc.. it makes total sense
May 27 06:55:17 <dyoung-zzzz> yeah, it costed me 30min.
May 27 06:55:30 <dyoung-zzzz> and a tube of epoxy.
May 27 06:55:55 <[g2]> right but there are K's of sw guys out there like me and much worse at soldering
May 27 06:56:14 <[g2]> I got 5 of the pins connected
May 27 06:56:43 <dyoung-zzzz> I guess I dont see what the issue is.
May 27 06:57:03 <dyoung-zzzz> making a nslu2 specific board and making the generic one takes the same amount of time.
May 27 06:57:26 <[g2]> umm.. these are modified nslu2's
May 27 06:57:43 <[g2]> Ah.. ok. sorry
May 27 06:57:54 <[g2]> you are right about the board you are making
May 27 06:58:25 <[g2]> I'm just it may not be the initial board I'm looking for the nslu2 dev kit launch
May 27 06:58:31 <[g2]> just saying
May 27 06:58:39 <dyoung-zzzz> of course if youre gonna hack stuff onto the USB-NIOS thing... thats differnt.
May 27 06:59:17 <dyoung-zzzz> and any of these solutions will absoultely require ep1220's expertise!
May 27 06:59:59 <[g2]> that would be ideal, but not required on 2 counts
May 27 07:00:19 <[g2]> 1) the compsys / digilent options will work just fine
May 27 07:00:34 <dyoung-zzzz> no reset input on digilent cable.
May 27 07:01:05 <[g2]> well making a digilent cable isn't too hard
May 27 07:02:27 <[g2]> I'd rather go straight to the usb solution that does serial and JTAG
May 27 07:02:55 <[g2]> s/does/does both/
May 27 07:03:01 <dyoung-zzzz> ... which is what the openjtag ft2232 board intends to do......
May 27 07:03:14 <dyoung-zzzz> as a configurable option....
May 27 07:03:39 <[g2]> right and I'm all for that with OpenJTAG
May 27 07:04:27 <ep1220> [g2]: How many boards do You need ?
May 27 07:04:42 <[g2]> I'd start with 10
May 27 07:04:47 <dyoung-zzzz> I'm gonna have to catch this up in logs, I'm really tired. and about to fall down.
May 27 07:05:00 <[g2]> sweet dreams my friend
May 27 07:05:01 <prpplague> so yall are going with a ft2232 chip?
May 27 07:05:25 <[g2]> prpplague, this is a work in progress and there are several things happening
May 27 07:05:44 <dyoung-zzzz> that seems to be the simplest solution at this point; but the caddilac project involves a FPGA.
May 27 07:06:27 <prpplague> [g2]: doing a fresh pcb layout before testing?
May 27 07:06:47 <[g2]> prpplague, no ?
May 27 07:07:21 <prpplague> [g2]: oh i saw where you said you had gotten geda and pcb, so i assumed you were doing a layout
May 27 07:07:29 <prpplague> my bad
May 27 07:07:50 <[g2]> no, I said that and the DVD will have those tools
May 27 07:08:20 <[g2]> prpplague, you may not have heard about the CD/DVD at all
May 27 07:09:29 <ep1220> [g2]: for this quantity a eval module + single sided PCB
May 27 07:09:31 <ep1220> for Voltage Reg. and headers 
May 27 07:09:31 <prpplague> oh ok, we just shoot me, i'm totally out of sync on whats going on hehe
May 27 07:09:38 <ep1220> might be cost-effective
May 27 07:09:50 <prpplague> [g2]: so you;ve already done a proto?
May 27 07:10:39 <dyoung-zzzz> Unfortunately, the proto only exists in my brain.
May 27 07:10:42 <[g2]> prpplague, I'm gonna use re-worked nslu2's to start, I've got a company doing rework now on first articles
May 27 07:10:44 <prpplague> hehe
May 27 07:11:10 <[g2]> actually, re-worked nslu2's, RV042s and RV082
May 27 07:11:12 <prpplague> ahh, and then use the ft2232 via usb?
May 27 07:11:20 <[g2]> and maybe the brand new RT042
May 27 07:11:28 <[g2]> nod.
May 27 07:11:37 <[g2]> the NSLU2 is just the first and flagship 
May 27 07:11:40 <dyoung-zzzz> I'm so sad.  my toy fund just took a major hit.
May 27 07:11:49 <dyoung-zzzz> I cant buy as many toys anymore.
May 27 07:11:54 <prpplague> hehe
May 27 07:12:03 <[g2]> dyoung-zzzz, why's that ?
May 27 07:12:08 <prpplague> so did mine, i just signed a lease on a beach house :(
May 27 07:12:20 <dyoung-zzzz> the toy fund got redirected into the car fund.
May 27 07:12:42 * [g2] is rebranding the toy fund as an "investment fund"
May 27 07:12:47 <[g2]> :)
May 27 07:12:52 <prpplague> my toy fund sometimes gets redirected into the nudie bar fund
May 27 07:13:03 <dyoung-zzzz> Hmm, in that case, the investment fund is gonna be taking a hit. :-)
May 27 07:13:30 <dyoung-zzzz> I suppose I could re-task the "childrens college fund" since I dont have children.
May 27 07:13:49 <[g2]> hey you'd be "investing" in the future :)
May 27 07:14:18 <dyoung-zzzz> true enough.
May 27 07:14:41 <dyoung-zzzz> which is part of the reasons as to why I'm kind of obsessed with CPLD stuffs.
May 27 07:15:10 <[g2]> and you could sell bumper stickers at that say "I spent my kids college fund on slugs!"
May 27 07:15:26 <dyoung-zzzz> hehe
May 27 07:15:42 <dyoung-zzzz> right next to, "Beaten paths are for beaten men"
May 27 07:15:57 <prpplague> hehe i like that one
May 27 07:16:18 * dyoung-zzzz fall down go sleep.
