| 13:28.35 | [g2] | ep1220, hello |
| 13:28.54 | [g2] | any luck with Q8 pin 1 ? |
| 13:29.15 | dyoung-zzzz | The magic pin |
| 13:29.21 | [g2] | nod. |
| 13:29.44 | [g2] | dyoung-zzzz, did you see that kitno455 had updated the wiki ? |
| 13:29.50 | dyoung-zzzz | yes. |
| 13:30.29 | dyoung-zzzz | based on that ka6sox and I reworked the candidate circuit for the the FT2232 based board. |
| 13:30.57 | [g2] | so what's the plan there ? |
| 13:31.15 | dyoung-zzzz | the circuit is clear in my brain. |
| 13:31.30 | dyoung-zzzz | but dunno how much is laid out in PCB, etc |
| 13:32.12 | [g2] | wasn't ka6sox planning on posting something ? Is this the same or different ? |
| 13:32.42 | [g2] | I've got pcb and geda on the DVD btw |
| 13:32.53 | dyoung-zzzz | cool. |
| 13:33.15 | dyoung-zzzz | he was gonna post something. but I dunno the status of that right now. |
| 13:33.34 | [g2] | well he's been busy and said it would be a little while |
| 13:33.48 | [g2] | I'm just wondering if his thing is similar or different to your thing |
| 13:34.02 | dyoung-zzzz | hehe hes been busy with my revenue project. |
| 13:34.11 | dyoung-zzzz | his thing is the same thing as my thing. |
| 13:34.42 | [g2] | your "revenue" project or a "real" project |
| 13:34.55 | dyoung-zzzz | now that I've worked with the 95xx abit, i have a much clearer idea of what to do. |
| 13:35.09 | dyoung-zzzz | "real" project for me, "revenue" project for him. |
| 13:35.15 | [g2] | nod. |
| 13:35.22 | [g2] | that's what I thought |
| 13:35.48 | [g2] | and I certainly don't want to distract him at all from that |
| 13:35.59 | dyoung-zzzz | Its done now. |
| 13:36.17 | [g2] | excellent |
| 13:36.28 | dyoung-zzzz | so on to funner stuff. :-) |
| 13:37.16 | ep1220 | g2: Hi. |
| 13:37.25 | ep1220 | not yet tried Q8/1 |
| 13:37.41 | ep1220 | want to find out if and how it is driven, before i hort it :-) |
| 13:37.51 | ep1220 | s/hort/short/ |
| 13:37.53 | [g2] | ep1220, Ok wonderful |
| 13:38.15 | [g2] | I should be getting 1st article re-worked boards back very soon |
| 13:38.26 | ep1220 | currently adding 3.3V to my 2232 module |
| 13:38.37 | [g2] | for serial ? |
| 13:38.46 | [g2] | or JTAG |
| 13:38.57 | [g2] | JTAG i'm guessing :) |
| 13:39.01 | ep1220 | can be used for both |
| 13:39.21 | ep1220 | the module takes 5V from USB |
| 13:39.23 | [g2] | OH.... yeah baby ! |
| 13:39.39 | ep1220 | the VCCio for ports A and B is on a pin. |
| 13:39.52 | ep1220 | i add a 3.3V regulator and connect to both |
| 13:41.05 | [g2] | so you'll handle both USB and JTAG via the usb connection back to the host |
| 13:41.37 | ep1220 | WOuld be possible. But I ignore serial at first step |
| 13:41.45 | [g2] | nod. |
| 13:42.10 | [g2] | what does the regulator cost ? |
| 13:42.10 | ep1220 | in theory the offical driver should suffice. |
| 13:42.50 | [g2] | and any idea of how much power it sucks ? |
| 13:43.02 | ep1220 | i#d say 40cents in small quantities. |
| 13:43.05 | dyoung-zzzz | we'll need that anyways to power the CPLD. |
| 13:43.38 | [g2] | I don't think ep1220's solution requires a CPLD |
| 13:43.56 | dyoung-zzzz | neither does ours, it allows for a wide range of voltages. |
| 13:44.18 | dyoung-zzzz | if I were talking to only a 3.3V device we could do it with the 2232 only. |
| 13:44.54 | [g2] | Ok here are my thoughs |
| 13:45.32 | [g2] | I'll have re-worked boards soon that have the serial header, JTAG header (less AC13) and 64 MB |
| 13:46.07 | [g2] | So what I'm missing is the serial and JTAG connector parts |
| 13:46.35 | [g2] | I'd love to build a single solution that does both as ep1220 is describing |
| 13:46.49 | dyoung-zzzz | yeah, thats the plan. |
| 13:46.59 | dyoung-zzzz | based on what we had discussed previously. |
| 13:47.01 | [g2] | ideally, the next batch has AC13 brought out and that connects up also |
| 13:47.26 | dyoung-zzzz | OR, PortB can be used for a control channel. |
| 13:47.53 | ep1220 | One caveat: the NSLU does not have Hw-handshake on serial |
| 13:47.53 | dyoung-zzzz | because we have a CPLD in there, it can easily be reconfigured. |
| 13:48.10 | [g2] | finally, I'm more interested in an initial solution just for the NSLU2 than a generic solution |
| 13:48.23 | [g2] | for the short-term |
| 13:48.56 | 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. |
| 13:49.18 | dyoung-zzzz | and that is what the additional CPLD affords us. |
| 13:49.32 | [g2] | right it's a volume thing |
| 13:50.12 | [g2] | and time-to-market ting |
| 13:50.14 | [g2] | and time-to-market thing |
| 13:50.51 | dyoung-zzzz | If I'm making a NSLU2 specific thing, its just a 2232 daughterboard with a bunch of wires hanging out of it. |
| 13:51.27 | [g2] | actually two headers |
| 13:51.43 | dyoung-zzzz | the nslu2 doesnt have a jtag header. :-) |
| 13:52.14 | [g2] | the re-work shop will probably have the wire coming out of the box and they could have a header attached |
| 13:52.55 | [g2] | which mates up to a simple board or different boards (i.e. The compsys connection, and a digilent) or our board |
| 13:53.47 | [g2] | dyoung-zzzz, My nslu2's will have a jtag header :) |
| 13:54.21 | dyoung-zzzz | well, mine does too, but thats not exactly gonna be nslu2 specific.... |
| 13:54.50 | [g2] | the cost is next to nothing for me to add it |
| 13:55.06 | [g2] | and for RMA etc.. it makes total sense |
| 13:55.16 | dyoung-zzzz | yeah, it costed me 30min. |
| 13:55.29 | dyoung-zzzz | and a tube of epoxy. |
| 13:55.54 | [g2] | right but there are K's of sw guys out there like me and much worse at soldering |
| 13:56.13 | [g2] | I got 5 of the pins connected |
| 13:56.42 | dyoung-zzzz | I guess I dont see what the issue is. |
| 13:57.02 | dyoung-zzzz | making a nslu2 specific board and making the generic one takes the same amount of time. |
| 13:57.25 | [g2] | umm.. these are modified nslu2's |
| 13:57.42 | [g2] | Ah.. ok. sorry |
| 13:57.53 | [g2] | you are right about the board you are making |
| 13:58.24 | [g2] | I'm just it may not be the initial board I'm looking for the nslu2 dev kit launch |
| 13:58.30 | [g2] | just saying |
| 13:58.38 | dyoung-zzzz | of course if youre gonna hack stuff onto the USB-NIOS thing... thats differnt. |
| 13:59.16 | dyoung-zzzz | and any of these solutions will absoultely require ep1220's expertise! |
| 13:59.58 | [g2] | that would be ideal, but not required on 2 counts |
| 14:00.18 | [g2] | 1) the compsys / digilent options will work just fine |
| 14:00.33 | dyoung-zzzz | no reset input on digilent cable. |
| 14:01.04 | [g2] | well making a digilent cable isn't too hard |
| 14:02.26 | [g2] | I'd rather go straight to the usb solution that does serial and JTAG |
| 14:02.54 | [g2] | s/does/does both/ |
| 14:03.00 | dyoung-zzzz | ... which is what the openjtag ft2232 board intends to do...... |
| 14:03.13 | dyoung-zzzz | as a configurable option.... |
| 14:03.37 | [g2] | right and I'm all for that with OpenJTAG |
| 14:04.26 | ep1220 | [g2]: How many boards do You need ? |
| 14:04.40 | [g2] | I'd start with 10 |
| 14:04.45 | dyoung-zzzz | I'm gonna have to catch this up in logs, I'm really tired. and about to fall down. |
| 14:04.58 | [g2] | sweet dreams my friend |
| 14:05.00 | prpplague | so yall are going with a ft2232 chip? |
| 14:05.23 | [g2] | prpplague, this is a work in progress and there are several things happening |
| 14:05.42 | dyoung-zzzz | that seems to be the simplest solution at this point; but the caddilac project involves a FPGA. |
| 14:06.25 | prpplague | [g2]: doing a fresh pcb layout before testing? |
| 14:06.45 | [g2] | prpplague, no ? |
| 14:07.20 | prpplague | [g2]: oh i saw where you said you had gotten geda and pcb, so i assumed you were doing a layout |
| 14:07.27 | prpplague | my bad |
| 14:07.48 | [g2] | no, I said that and the DVD will have those tools |
| 14:08.18 | [g2] | prpplague, you may not have heard about the CD/DVD at all |
| 14:09.27 | ep1220 | [g2]: for this quantity a eval module + single sided PCB |
| 14:09.29 | ep1220 | for Voltage Reg. and headers |
| 14:09.29 | prpplague | oh ok, we just shoot me, i'm totally out of sync on whats going on hehe |
| 14:09.36 | ep1220 | might be cost-effective |
| 14:09.48 | prpplague | [g2]: so you;ve already done a proto? |
| 14:10.36 | dyoung-zzzz | Unfortunately, the proto only exists in my brain. |
| 14:10.40 | [g2] | prpplague, I'm gonna use re-worked nslu2's to start, I've got a company doing rework now on first articles |
| 14:10.42 | prpplague | hehe |
| 14:11.08 | [g2] | actually, re-worked nslu2's, RV042s and RV082 |
| 14:11.09 | prpplague | ahh, and then use the ft2232 via usb? |
| 14:11.18 | [g2] | and maybe the brand new RT042 |
| 14:11.26 | [g2] | nod. |
| 14:11.35 | [g2] | the NSLU2 is just the first and flagship |
| 14:11.38 | dyoung-zzzz | I'm so sad. my toy fund just took a major hit. |
| 14:11.46 | dyoung-zzzz | I cant buy as many toys anymore. |
| 14:11.51 | prpplague | hehe |
| 14:12.01 | [g2] | dyoung-zzzz, why's that ? |
| 14:12.06 | prpplague | so did mine, i just signed a lease on a beach house :( |
| 14:12.18 | dyoung-zzzz | the toy fund got redirected into the car fund. |
| 14:12.45 | [g2] | :) |
| 14:12.52 | prpplague | my toy fund sometimes gets redirected into the nudie bar fund |
| 14:13.03 | dyoung-zzzz | Hmm, in that case, the investment fund is gonna be taking a hit. :-) |
| 14:13.30 | dyoung-zzzz | I suppose I could re-task the "childrens college fund" since I dont have children. |
| 14:13.49 | [g2] | hey you'd be "investing" in the future :) |
| 14:14.18 | dyoung-zzzz | true enough. |
| 14:14.40 | dyoung-zzzz | which is part of the reasons as to why I'm kind of obsessed with CPLD stuffs. |
| 14:15.09 | [g2] | and you could sell bumper stickers at that say "I spent my kids college fund on slugs!" |
| 14:15.26 | dyoung-zzzz | hehe |
| 14:15.41 | dyoung-zzzz | right next to, "Beaten paths are for beaten men" |
| 14:15.57 | prpplague | hehe i like that one |
