| 01:44.09 | lennert | sop |
| 01:44.11 | lennert | so, even |
| 01:44.17 | lennert | i'm trying to get the dcm to work |
| 01:44.22 | lennert | and i'm having a problem with the feedback path |
| 01:44.44 | lennert | i'm squeezing the CLKFX output through a bufg back into the CLKFB input of the dcm, and i get: |
| 01:44.50 | lennert | ERROR:PhysDesignRules:740 - Invalid DCM configuration. The DCM comp |
| 01:44.50 | lennert | <PROTECTED> |
| 01:44.50 | lennert | <PROTECTED> |
| 01:45.02 | lennert | but i do _not_ have clkfx looped back to clkfb directly. |
| 01:45.15 | lennert | oh |
| 01:45.27 | lennert | d'oh |
| 01:45.27 | lennert | sorry |
| 01:47.25 | lennert | clkfx is multiplied so that won't work |
| 01:47.39 | lennert | i have to use clk0, but since i don't use the 1:1 clock, it doesn't matter |
| 01:53.15 | lennert | any idea why it gives me this all the time: |

| 02:42.31 | lennert | whee, pong in supervga |
| 02:42.55 | lennert | now all we need is some sound when the ball hits something |
| 02:43.09 | lennert | but i guess i can implement that by sending a Ctrl-G over the serial port to a minicom on the pc side :P |

| 07:20.51 | ka6sox | ya.... |
| 07:21.05 | ka6sox | very tired... |
| 07:21.15 | ep1220 | server troubles of last week sorted out ? |
| 07:21.38 | ka6sox | I think so... |
| 07:21.46 | ep1220 | i was just about heating up the soldering iron |
| 07:22.12 | ka6sox | excellent. |
| 07:24.16 | ka6sox | send pictures? |
| 07:24.35 | ka6sox | of blank board and also assembled ones? |
| 07:24.46 | ep1220 | not yet. will do this afertnoon |
| 07:24.53 | ep1220 | assembly just starts .. |
| 07:25.04 | ka6sox | okay I let you do that...cya later! |

| 12:48.37 | lennert | i had something really weird the other day |
| 12:48.44 | lennert | i was running a program to flash some LEDs |
| 12:48.55 | lennert | then, without resetting the spartan3, i loaded pong.bit via JTAG |
| 12:49.05 | lennert | pong started playing on the screen, but the LEDs kept on flashing |
| 12:49.23 | lennert | so.. configure the device twice without resetting and it'll run two bitstreams simultaneously? :) |
| 12:50.36 | lennert | (what my loader should be doing, but doesn't at present, is to check the DONE pin and optionally run JSHUTDOWN or something) |
| 12:56.45 | vmaster_ | heh, you should load 128 ublaze cores then, without resetting ;) |
| 12:57.51 | lennert | i guess that they were using unrelated logic so it didn't blow up |
| 12:57.59 | lennert | still weird that it allows you to do this |
| 12:58.07 | lennert | :) |

| 14:46.00 | ep1220 | hi ka6sox-zzzz |
| 14:46.04 | ep1220 | I have some pics of the JTAG IF in http://de.share.geocities.com/at2cn/JtagIF_img.pdf |
| 14:48.42 | prpplague | ep1220: oh wow, nice looking |
| 14:48.51 | ep1220 | prpplague: Thx |
| 14:49.43 | prpplague | ep1220: where can i get one :) |
| 14:50.39 | ep1220 | I do have some more of the PCBs |
| 14:51.04 | ep1220 | You could solder the parts yourself ? |
| 14:51.13 | ka6sox-zzzz | Diese Website ist momentan nicht verfügbar |
| 14:52.25 | ep1220 | Did not know they limit acess at this site |
| 14:52.45 | ka6sox-zzzz | no problem.... |
| 14:52.48 | ep1220 | the errormsg says try again in an hour :-( |
| 14:53.50 | ka6sox-zzzz | oh well...no problem |
| 15:00.03 | ka6sox-zzzz | those are very good pix! |
| 15:00.22 | ep1220 | ka6sox-zzzz: Thx |
| 15:01.32 | prpplague | ep1220: yea i could solder it myself, but i'd probably send it to our assembly department |
| 15:01.51 | prpplague | ep1220: have you got schematics available? |
| 15:03.09 | prpplague | ep1220: doh, did you remove the pdf? |

| 15:03.55 | ep1220 | Too many accesses. |
| 15:03.58 | prpplague | ahh |
| 15:04.13 | prpplague | bummer i was gonna forward a copy to my boss |
| 15:04.33 | ep1220 | it also says: Try again in an hour. |
| 15:04.39 | prpplague | oh ok |
| 15:05.08 | ep1220 | Must update schematics and BOM. |
| 15:05.16 | ep1220 | Will be available tomorrow |
| 15:05.21 | prpplague | ep1220: ok thanks |
| 15:05.35 | prpplague | ep1220: i suspect my boss will want to make a couple |
| 15:06.01 | prpplague | ep1220: uh sorry i didn't even think to ask, this is an open design right? |
| 15:07.39 | ep1220 | prpplague: There is only marginal SW available so far. |
| 15:07.57 | prpplague | ep1220: hehe, well thats what i do |
| 15:08.22 | ep1220 | And I also should verify HW functionality first ;-) |
| 15:08.36 | prpplague | ep1220: i've been tinkering with ex-usb based stuff for jtag but this looks interesing too |
| 15:08.51 | ep1220 | what is ex-usb ? |
| 15:09.01 | prpplague | sorry ez-usb |
| 15:09.11 | prpplague | http://www.elinux.org/wiki/EzUsb |
| 15:09.16 | ep1220 | I know this one |
| 15:09.36 | ep1220 | Also evaluated it for JTAG. |
| 15:10.00 | prpplague | i was using it for other projects so it was handy to test jtag with |
| 15:16.08 | ep1220 | prpplague: What JTAG CLK rate did you achieve ? |
| 15:18.32 | prpplague | ep1220: haven't really spent any significant time testing, been working on another project, but it was about 2x faster than my wiggler |
| 15:19.14 | bullet | ep1220: what clk rate do you achieve with your tagger? |
| 15:19.33 | lennert | i get about 300khz with my parallel digilent cable |
| 15:19.39 | lennert | ~330khz |
| 15:20.49 | prpplague | bullet: like i said, i really didn't spend any time doing testing, i got pulled off another project, won't be able to get back on it for a couple of weeks |
| 15:21.19 | bullet | prpplague: i actually asked ep1220 about his ftdi based jtagger |
| 15:21.38 | prpplague | bullet: ahh, sorry mis read |
| 15:21.59 | ep1220 | bullet: the chip can do 6MHz (but the clock is not continous) |
| 15:22.08 | ep1220 | and then there is the USB latency |
| 15:22.20 | ep1220 | so it will depend a lot on the SW |
| 15:22.36 | ep1220 | and what You want to do. |
| 15:22.55 | ep1220 | It certainly will not be on par with an Abatron or Windriver USB probe |
| 15:23.27 | bullet | so is the price :) |
| 15:27.25 | ep1220 | bullet: right :-) |
| 16:48.28 | [g2] | ep1220-log do you have working boards ? |
