| mithro | If you could get an Opsis for $200 USD each -- how would that change your thoughts on the Opsis? | 00:53 |
|---|---|---|
| cr1901_modern | mithro: I can't give an unbiased opinion, but if that were the case my thought process would be along the lines of: "this totally kicks the ass of the Pipistrello" | 01:07 |
| cr1901_modern | (well it still does :P, but that would seal the deal) | 01:07 |
| mithro | The pipistrello is nice and small :-P | 01:31 |
| cr1901_modern | Yes, but... it has a few issues that prevent me from recommending it despite the massive LX45 size. Mainly, no built-in Ethernet, and the FT2232H connections are insufficient to use one of the FT2232H's channels in queue mode. | 01:39 |
| cr1901_modern | (Opsis gets around this by... well, using the FX2) | 01:39 |

| whatnick | I am happy with a $200 opsis | 06:23 |
| whatnick | now I have an ice40 and the mimis | 06:23 |
| whatnick | xilinix chain on windows meh | 06:24 |
| whatnick | icestorm almost there | 06:24 |

| paddatrapper | mithro: built sigrock with your additions. Ran into a problem with the ethernet - I have no gigabit nics, so need a cross-over cable. Ordered the USB one | 13:56 |
| froztbyte | paddatrapper: yo | 15:43 |
| paddatrapper | froztbyte: hey | 15:43 |
| froztbyte | paddatrapper: I tried to phone you earlier but apparently my network didn't allow it | 15:43 |
| froztbyte | we're on for 2pm tomorrow | 15:43 |
| froztbyte | will that work for you? | 15:43 |
| paddatrapper | froztbyte: odd. Cool that works for me | 15:43 |
| froztbyte | (I only heard that time from PvO ~4pm) | 15:43 |
| froztbyte | kk | 15:43 |
| froztbyte | cool | 15:43 |
| froztbyte | mithro: I'd take some opsis boards at $200 | 15:45 |
| froztbyte | I don't really know why the $200 is relevant | 15:45 |
| froztbyte | but I'd buy such hardware | 15:45 |
| froztbyte | oh right it's a bunch cheaper. yeah, I'd go for that. would like 1080p capture though | 15:57 |
| froztbyte | not sure I yet know anyone who does 4k capture | 15:57 |
| froztbyte | whatnick: what are you doing with the ice40? I keep wanting to buy one and then fighting with myself over not having an electronics lab | 15:58 |

| paddatrapper | mithro: later in the week I'll make a crossover cable to use until the USB adaptor arrives | 17:10 |
| CarlFK | paddatrapper: you don't need crossover cable if one of the ports is gig-e | 17:11 |
| froztbyte | 13:55:51 < paddatrapper> mithro: built sigrock with your additions. Ran into a problem with the ethernet - I have no gigabit nics, so need a cross-over cable. Ordered the USB one | 17:20 |
| CarlFK | hey froztbyte | 17:23 |
| CarlFK | paddatrapper: what are you hooking up to what? the Opsis is gig-e - also many 100's do auto crossover negotiation (I think that's what it is called) | 17:24 |
| froztbyte | hallous | 17:28 |
| paddatrapper | CarlFK: then maybe the issue was somewhere else. I just couldn't connect to the opsis over ethernet last night. Assumed it was that and ran out of time to debug properly | 17:33 |
| paddatrapper | CarlFK: connecting opsis to laptop which is 10/100 NIC | 17:33 |
| CarlFK[m] | paddatrapper a linux kernel hacker (bwh Ben Hutchings) who also worked for a nic company said auto crossover negotiation is part of the gig-e spec. | 17:36 |
| CarlFK[m] | I would hope that the Opsis followed that bit of the spec. I would guess it is implemented in the chips and so it doesnt have a choice. | 17:37 |
| paddatrapper | CarlFK[m]: ok. I'll be able to test some more later in the week when I don't have assignments breathing down my neck | 17:38 |
| froztbyte | CarlFK[m]: MDI-X (the name of the auto-negotiation) | 17:38 |
| froztbyte | paddatrapper: `ethtool ethn` to see interface capabilities | 17:39 |
| paddatrapper | froztbyte: thanks. Shall check in a bit | 17:40 |
| CarlFK | carl@twist:~$ ethtool p3p1 | 17:44 |
| CarlFK | Supports auto-negotiation: Yes | 17:44 |
| CarlFK | neat - now to port that to the Opsis :p | 17:44 |
| paddatrapper | CarlFK[m]: it does support auto-negotiation, so must be something else | 17:44 |
| paddatrapper | Probably something stupid I missed. It was pretty late last night when I tried it | 17:45 |

| cr1901_modern | _florent_: Ping if you're still awake? | 20:30 |
| cr1901_modern | What JTAG adapter do you use to program Opsis from Windows? And what openocd commands do you use? | 20:31 |

| cr1901_modern | mithro: Current status: Bitbang write/read works on the opsis, but the xmodem xfer crashes before I even get into the xmodem routine. | 22:47 |
| * cr1901_modern sighs heavily... all this work, just to get a nearly-impossible-to-debug-crash-in-a-varargs-routine | 23:02 | |
| cr1901_modern | I wonder if I'm going to be desperate enough to do an iverilog simulation (that's gonna take hours, and I don't even know how to feed it input to a fake UART...) | 23:22 |
| cr1901_modern | It's the same goddamn bug w/ the memory bus that I couldn't diagnose back in January, isn't it T_T? | 23:26 |
