| mithro | CarlFK: you want to watch the FX2 reset line while the fx2_reboot command occurs | 02:03 |
|---|---|---|
| mithro | CarlFK: it should go low then high | 02:03 |
| mithro | CarlFK: I have test patterns at https://github.com/timvideos/test-patterns | 02:07 |
| tpb | Title: GitHub - timvideos/test-patterns: Test patterns for debugging video problems. (at github.com) | 02:07 |
| CarlFK | mithro: k3 2 is high. how long should it stay low when reset? | 02:22 |
| mithro | CarlFK: for the entire period that it says "turning FX2 off, turning it on" | 02:22 |
| CarlFK | k | 02:22 |
| mithro | CarlFK: obviously it isn't doing that, because otherwise you wouldn't see the turning it on bit | 02:23 |
| CarlFK | mithro: scope hooked to 2, we don't see anything on the scope when I do this: | 02:37 |
| CarlFK | HDMI2USB>debug fx2_reboot usbjtag | 02:37 |
| CarlFK | fx2: Turning off. | 02:37 |
| CarlFK | fx2: Turning on. | 02:37 |
| mithro | CarlFK: Did you keep the jumper connected? | 02:38 |
| CarlFK | no | 02:38 |
| mithro | CarlFK: the two pins still need to be connected | 02:38 |
| CarlFK | mithro: I did see a short drop | 02:42 |
| mithro | CarlFK: picture? | 02:42 |
| mithro | How much did it drop? Did it drop to zero? | 02:42 |
| CarlFK | "no" "but this scope is really crappy so you have to...." fiddling... | 02:45 |
| CarlFK | "it gets to 2 v" | 02:47 |
| CarlFK | "the reset is close to 50 us" | 02:48 |
| CarlFK | (microseconds) | 02:48 |
| mithro | CarlFK: It needs to get to under 1v | 02:49 |
| mithro | So, I guess we aren't holding it low for long enough | 02:50 |
| CarlFK | pic coming... | 02:50 |
| CarlFK | "yes" | 02:50 |

| mithro | That scope actually has pretty good support for capturing under Linux | 02:52 |
| mithro | CarlFK: and you log a github issue about this with that picture attached? | 02:56 |
| mithro | CarlFK: although it would be better if you had 0V and 3.3V measured | 02:57 |
| CarlFK | mithro: better if I what? | 02:57 |
| mithro | CarlFK: the oscilliscope picture | 02:58 |
| CarlFK | mithro: this is what I get when I hit the reset button | 03:01 |

| tpb | Title: Google+ (at plus.google.com) | 03:01 |
| CarlFK | hmm, same url? | 03:01 |
| CarlFK | correct pic, so pft | 03:02 |
| CarlFK | where reset button is the white button on the board labeled sw1 | 03:03 |
| mithro | CarlFK: that looks right? | 03:04 |
| CarlFK | yes | 03:04 |
| CarlFK | hitting the case button that is hooked to those headers... does not look right.. | 03:05 |
| CarlFK | click, posting... | 03:06 |
| mithro | CarlFK: What do you mean? | 03:06 |

| tpb | Title: Google+ (at plus.google.com) | 03:06 |
| mithro | CarlFK: where have you connected the case button too? | 03:09 |
| mithro | CarlFK: and can you measure the resistance of the case button | 03:09 |
| CarlFK | case switch is on 5,7 of P14 | 03:12 |
| mithro | Are you with someone who can read schematics? | 03:15 |
| mithro | Show them the schematic | 03:15 |
| mithro | Also try shorting the pins with a screw driver rather then the switch | 03:17 |
| mithro | Also see what the voltage on them is when not shorted | 03:17 |
| CarlFK | case switch is .4 ohm | 03:19 |

| *** panther is now known as sab_123 | 03:20 | |
| mithro | That is good, what we expected | 03:25 |
| mithro | CarlFK: can you log the bug so I can link it in the fix? | 03:38 |
| CarlFK | mithro: 3v across the 5,7 of P14 (what I have the case switch hooked to) | 03:39 |
| CarlFK | mithro: what repo should I log the bug under? | 03:39 |
| mithro | CarlFK: The HDMI2USB-misoc-firmware repo | 03:42 |
| mithro | CarlFK: so.... | 03:55 |
| CarlFK | mithro: entering now.. do I need a description? | 03:56 |
| mithro | CarlFK: yes | 03:56 |
| CarlFK | mithro: fx2: Turning on. happens so fast the signal never drops low enough. | 03:57 |
| CarlFK | right ? | 03:57 |
| mithro | CarlFK: FX2 doesn't reboot during the fx2_reboot command, this appears to be because the reset line doesn't appear to drop low enough | 03:57 |
| mithro | or something like that | 03:57 |
| CarlFK | https://github.com/timvideos/HDMI2USB-misoc-firmware/issues/221 | 03:59 |
| mithro | CarlFK: did you attach the picture? | 03:59 |
| CarlFK | attached | 04:03 |
| mithro | CarlFK: thanks, fix incoming | 04:04 |
| CarlFK | 11pm. I need to get to the store, then home, then I can try to figure out how to flash | 04:06 |

| mithro | CarlFK: btw, it's a 4 day weekend here in Australia (we get both Friday and Monday as public holidays) | 04:52 |
| mithro | CarlFK: so it is a good chance to get a bunch of HDMI2USB hacking done | 04:53 |
| CarlFK | mithro: the only time I have been able to flash my Opsis is by accidentally getting it into the mode by doing something on power up | 04:53 |
| mithro | CarlFK: oh, you can remove one of the jumpers near the FX2 to get it into "fallback mode" which is an easy way to replicate that | 04:53 |
| CarlFK | k - and I get a different usb id, right ? | 04:54 |
| mithro | CarlFK: or you could use the scripts I pointed out... | 04:54 |
| CarlFK | I tried your script (one) | 04:54 |
| mithro | CarlFK: this one -> https://github.com/mithro/HDMI2USB-mode-switch/blob/opsis-prod/opsis-flash.sh | 04:55 |
| tpb | Title: HDMI2USB-mode-switch/opsis-flash.sh at opsis-prod · mithro/HDMI2USB-mode-switch · GitHub (at github.com) | 04:55 |
| mithro | CarlFK: you made sure you were on the opsis-prod branch right? | 04:55 |
| CarlFK | it wasn't that one. it was a 600 line .py | 04:55 |
| mithro | CarlFK: no idea what you are talking about then? :P | 05:01 |
| mithro | CarlFK: you probably don't want the first two lines of that script (the eeprom programming bit) | 05:01 |
| mithro | CarlFK: deeprave and micolous also know how to flash an Opsis | 05:01 |
| mithro | but they haven't really been around much lately.... | 05:02 |
| mithro | :( | 05:02 |
| CarlFK | mithro: might have been 200 lines. hdmi2usb-mode-switch.py looks familiar. | 05:02 |

| sab_123 | mithro, I am using the triple spark | 05:09 |
| sab_123 | mithro, there seems to be something funny | 05:09 |
| mithro | triple spark? | 05:10 |
| sab_123 | let me create github repo | 05:10 |
| CarlFK | mithro: for my box of stuff in a case I need a system to stream usb->gigE. any suggestions on either pi sized things or a rack mount i7 ? | 05:14 |
| mithro | CarlFK: the C3VOC guys probably have some good suggestions | 05:15 |
| mithro | CarlFK: I'd recommend getting something which has USB3.0 and GigE | 05:15 |
| CarlFK | usb3, good idea. | 05:16 |
| mithro | I mean, it is hard not to get something which is USB 3.0 these days | 05:16 |
| mithro | Unless you go embedded hardware | 05:16 |
| CarlFK | mithro: I am leaning twards the higher end so that I have another box to do encoding, like for streaming | 05:16 |
| mithro | CarlFK: yeah, MaZderMind had some cool little things he called "minions" | 05:17 |
| CarlFK | they are not rack mount | 05:17 |
| CarlFK | they are like mac minis. | 05:17 |
| CarlFK | I'll do some shopping in the next week or so. | 05:20 |
| mithro | CarlFK: yeah, but I was wondering if they could come in rack-mount versions | 05:20 |
| mithro | CarlFK: They might be mini-itx boards inside the case? | 05:20 |
| mithro | CarlFK: dunno much about them | 05:20 |

| madara | hello,I was going through the idea list of Timvideos and under that I found HDMI2USB interesting.I have a small doubt in that,should we propose hardware idea or software idea for the development ? | 10:15 |
| mithro | ssk1328_: It is unclear at the moment, I think we might wait until after the mid-term evaluation | 10:17 |
| mithro | madara: There should be a large coding component of your project | 10:18 |
| mithro | madara: but it can include hardware development | 10:18 |
| madara | okay thanks :) | 10:19 |
| *** ssk1328 has joined #timvideos | 10:20 | |
| *** ssk1328_ has quit IRC | 10:22 | |
| ssk1328 | mithro: So before midterm I can develop on any FPGA of choice? I can get hold of Spartan3E or Virtex5, will that be Ok? Otherwise I can myself pay to get Spartan6 FPGA board. | 10:22 |
| mithro | ssk1328: Depends on the project, most of the stuff can be done without hardware | 10:23 |
| mithro | ssk1328: Where you the hardware mixing one? | 10:23 |
| ssk1328 | Yeah | 10:23 |
| ssk1328 | Ok so if the code is synthesizable and works in simulation than we can safely assume it will work with hardware as well. | 10:24 |
| *** ssk1328_ has joined #timvideos | 10:25 | |
| *** madara has left #timvideos | 10:28 | |
| mithro | ssk1328: you can't assume that, but it is a good start | 10:29 |
| ssk1328 | But the final demostration with HDMI in and out can be done only with Opsis board, as other board might not have so many HDMI interfaces. | 10:32 |
| mithro | ssk1328: correct | 10:32 |
| ssk1328 | Can I somehow purchase Opsis board right now? I mean is available for selling? | 10:34 |
| ssk1328 | *is it | 10:34 |
| mithro | ssk1328: yes, you can purchase from crowdsupply, but if you wait a couple of weeks it should be avaliable from the Numato website too | 10:39 |

| CarlFK | mithro: any hints on what jumper will let me flash it? | 14:35 |
| mithro | CarlFK: no jumper will let you flash, there is a jumper which will prevent the HDMI2USB fx2 firmware from being loaded | 14:35 |
| mithro | CarlFK: the one marked something like SDA | 14:36 |
| CarlFK | mithro: I see 4 sets of jumper headers - none like SDA | 14:39 |
| mithro | CarlFK: look at the schematic, its the one which connects the I2C line to the Cypress from the FPGA | 14:39 |
| mithro | CarlFK: but if you want to replicate the way I've flashed and Opsis, you should go down the mode-switch route | 14:40 |
| CarlFK | mithro: Numato-Opsis-v3-prod-3-g83e7bd5.pdf - ^f find i2c "Not Found" | 14:44 |
| mithro | CarlFK: I2C has two signals, SDA and SCK (or something similar to that) | 14:45 |
| CarlFK | your way i might run on a test box if I get desperate | 14:45 |
| CarlFK | 11 SDA, 1 SCK but it is on micro_sd so I am guessing that isn't it | 14:47 |

| CarlFK | conn_2 p18 | 15:08 |
