| Bertl | mithro: opsis board arrived \o/ | 03:11 |
| Bertl | it is huge and black and mostly empty :) | 03:11 |
| mithro | Bertl: It's designed to be mounted in an Mini-ITX case | 03:12 |
| Bertl | why not Nano-ITX :) | 03:14 |
| mithro | Bertl: those cases are much more expensive and hard to source | 03:14 |
| Bertl | or Pico-ITX :) | 03:14 |
| Bertl | anyway, nice board | 03:15 |
| mithro | Bertl: we also don't have the space constraints of trying to fit in a handheld camera :) | 03:39 |
| xfxf | mithro: sort of, @ work | 03:40 |
| mithro | Bertl: Have you thought any more about how you might interface your current setup with the Opsis? | 03:56 |
| Bertl | yes, we will du a TOFE plugin board which directly connects to a dual plugin module on the Beta, most likely over 3x mini displayport cables | 04:08 |
| Bertl | *do | 04:08 |
| Bertl | (to link up over 12 lvds pairs) | 04:09 |
| mithro | Bertl: I was going to suggest you use http://www.amazon.com/Tenext-Express-Adapter-Flexible-Extension/dp/B00EY7BW0C/ref=sr_1_1?ie=UTF8&qid=1444710945&sr=8-1&keywords=pci+express+8x | 04:38 |
| mithro | Bertl: then you just need an adapter which has PCB fingers on both sides | 04:38 |
| mithro | one side with standard PCI-Express 8x and the other with your interface | 04:38 |
| Bertl | yeah, but due to the huge size of the opsis, this is impractical :) | 04:40 |
| Bertl | hence the mini DP cables come in | 04:40 |
| Bertl | was thinking about a FFC/FPC solution first, but I'm not sure about the signal quality there | 04:41 |
| mithro | Bertl: those cables must be PCI-Express compatible which is significantly faster then our signal speed | 04:42 |
| mithro | Bertl: the problem I think would be more if they are flexible enough | 04:43 |
| Bertl | the FPCs or the mini DP cables? | 04:44 |
| mithro | The riser cable thingy I listed above | 05:16 |
| mithro | xfxf: ping me when you have 30 minutes | 05:17 |
| Bertl | yeah, I'm not too confident, that those flat cables are good for signal integrity :) | 05:43 |
| mithro | Bertl: People use them in servers :P | 05:43 |
| Bertl | people do strange things ... | 05:43 |
| Bertl | mithro: btw, one real criticism on the opsis design: you could have connected a bunch of unused I/Os to a block of LEDs for status/debugging | 05:47 |
| mithro | Bertl: We ran out of IO pins, the unused IO pins are hard to breakout and on 1V5 VCCIO bank. | 05:49 |
| Bertl | level converters are cheap, especially if you can leave them out later, but okay, the breakout part is an argument | 05:51 |
| mithro | Bertl: I had asked them to break out all the remaining IO on the 1V5 bank to a header and there was lots of push back about the difficulty of doing so. | 05:52 |
| Bertl | but I see Y3 goes to the switch and probably isn't harder to break out than V3 or T3 | 05:52 |
| Bertl | D1 is probably trivial | 05:53 |
| Bertl | at least P15/CONN_5 gives some hope :) | 05:55 |
| mithro | Bertl: The slow speed IO expansion board gives you a lot more debugging options | 05:56 |
| Bertl | which plugs into the PCIe, so is no option for debugging :) | 05:56 |
| mithro | Bertl: actually, maybe we should do a HDMI to LED debugging tool? | 05:57 |
| Bertl | yes, that would probably be a good idea | 05:58 |
| Bertl | a saleae connector cable with an HDMI plug | 05:58 |
| mithro | Bertl: also, using the FX2 as a serial port and printing out to the UART turns out to be a pretty good debugging once you have that working | 05:58 |
| Bertl | uart is nice, but doesn't help much with timing and similar | 06:00 |
| Bertl | I see an LED labeled DONE (D1) on the board but I can't find it on the schematic (for some reason it is not searchable) | 06:02 |
| Bertl | (the pdf version) | 06:02 |
| mithro | It's connected to the DONE pin on the FPGA (which means the FPGA is done programming). | 06:03 |
| Bertl | ah, good, so I can use that for now :) | 06:03 |
| mithro | Bertl: I didn't think that the DONE pin can be configured as a user IO? | 06:03 |
| mithro | Bertl: it's on the FPGA_Power sheet | 06:04 |
| Bertl | yeah, seems like the spartan6 can't take control of the done pin | 06:12 |
| mithro | Bertl: do you have a LED which works on 1V5? | 06:13 |
| mithro | Bertl: if so, you can put it on the DEBUG header | 06:13 |
| Bertl | yeah, I figured, but I don't have one at home | 06:14 |
| mithro | Bertl: I've just been attaching my oscilloscope to those pins if I need to get some timing information | 06:14 |
| Bertl | yes, that and logic analyzer should work | 06:14 |
| mithro | Bertl: Assuming your logic analyzer goes down to 1V5 | 06:14 |
| Bertl | yes, luckily it does | 06:15 |
| mithro | tumbleweed: ping? | 06:26 |
| mithro | tumbleweed: I'm wondering if there is a support way to "send a message to the user" when installing a new deb package | 06:27 |
| tumbleweed | mithro: you can put entries in NEWS.debian. People who care about such things use apt-listchanges which will display the message | 06:29 |
| tumbleweed | mithro: or for very serious things, a debconf prompt | 06:29 |
| mithro | tumbleweed: Oh, I guess - is there a way to trigger udev to do a virtual unplug/plug for a device? | 06:31 |
| tumbleweed | don't know | 06:34 |
| xfxf | isn't there something you can echo into /proc to reset a USB device? | 06:34 |
| xfxf | i vaguely remember doing that many years ago | 06:34 |
| mithro | tumbleweed: What is the best way to run some udev commands after a package is installed? | 06:41 |
| tumbleweed | in the postinst script | 06:42 |
| mithro | tumbleweed: https://github.com/mithro/ixo-usb-jtag/issues/1 | 06:46 |

| tumbleweed | seems plausible | 06:50 |
| *** se6astian|away is now known as se6astian | 07:03 | |
| mithro | Bertl: so it sounded like you were already playing with the board? | 07:20 |
| CarlFK | mithro: when building ... why ./configure --prefix=/opt/openocd | 07:23 |
| mithro | CarlFK: so you can uninstall by doing a "rm -rf /opt/openocd" | 07:23 |
| CarlFK | eww | 07:23 |
| Bertl | without powering it up, yes, sounds strange but I don't have a 12V supply at hand, I have to find a plug so that I can use the bench power supply | 07:24 |
| mithro | Bertl: I need to check, but I believe any power supply in the range 9V to 18V should work | 07:29 |
| mithro | The 12V isn't used directly. | 07:29 |
| Bertl | I have 24V with a 2.5mm plug, but I guess that will be too much | 07:31 |
| Bertl | and I presume 5V (have a bunch of those for the Betas) is too low? | 07:31 |

| xfxf | ah, rad, good to hear you got it working | 09:34 |
| *** Travis__ has left #timvideos | 09:39 | |
| CarlFK | xfxf - from what I can tell, you need to be in just the right dir when running openocd because board/digilent_atlys.cfg has paths to other files | 09:44 |
| CarlFK | source [find interface/usb-jtag.cfg] | 09:45 |
| CarlFK | that might be becuase I didn't "make install" but even when I did I had to cd /opt/openocd/something | 09:46 |
