| Joelw | So what's the deal with HDMI input, anyway? | 04:49 |
| Joelw | Someone's asked me for help with getting the Atlys XAPP495 dvi_demo video switcher working, and I'm very hazy on how to do it | 04:50 |
| Joelw | Does hdmi2usb implement any sort of EDID ROM for the inputs? Or do you pass it through? | 04:50 |
| *** paradisaeidae has joined #timvideos | 04:50 | |
| Joelw | I presume that the jumper settings in https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/platforms/atlys.py would apply to dvi_demo too | 04:51 |
| tpb | Title: HDMI2USB-misoc-firmware/atlys.py at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 04:51 |
| Joelw | Unfortunately I've lent my Atlys to someone so I'm no longer able to actually test it | 04:51 |
| Joelw | It'd be nice if I could update my Atlys page with the definitive "Here's how to get XAPP495 working"guide | 04:51 |
| CarlFK | Joelw: EDID is kinda burned into it | 05:08 |
| CarlFK | kinda because you can change it to on of about 12 | 05:08 |
| *** paradisaeidae has quit IRC | 05:11 | |
| Joelw | CarlFK: Ah, you present a choice of EDID 'ROM' to each of the inputs? | 05:29 |
| CarlFK | Joelw: um... no. you config the whole thing (2 inputs, 2 outputs and the mjpeg encoder) to a single setting | 05:30 |
| CarlFK | that's what the inputs send in the edid as the 1 supported res | 05:30 |
| CarlFK | and is is what the outputs send regardless of what they get via edid of the device they are sending to | 05:31 |
| Joelw | Sounds good! I reckon that's what dvi_demo needs to fix it - just present an EDID to the inputs with only 1280x720 or something | 05:32 |
| CarlFK | http://paste.ubuntu.com/16402485/ that's what is supported | 05:33 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 05:33 |
| CarlFK | currently. more can be added if someone adds it to the firmware | 05:33 |
| CarlFK | HDMI2USB>video_mode 9 | 05:34 |
| CarlFK | Setting video mode to 1280x720 @60Hz | 05:34 |
| Joelw | Thanks! I might see if I can add that to dvi_demo somehow. Bit tricky to test without a board, but might be fun :) | 05:35 |
| Joelw | Does the Vivado download include ISE? | 05:37 |
| *** paradisaeidae_ has joined #timvideos | 05:37 | |
| Joelw | I've got a Nexys Video in the post, so I don't want to download two things if I don't have to! :) | 05:37 |
| CarlFK | Vivado download ? | 05:39 |
| CarlFK | I have looked at the source code, and thanks to tim's scrips that do everything I have built ... but that's about the extent of what I know about the tool chain | 05:40 |
| Joelw | Vivado's Xilinx tool for 7-series devices. It looks like they used to be bundled together, but haven't been since 2013. | 05:40 |
| Joelw | Cool, no worries :) | 05:40 |

| Joelw | mithro: Yes! I don't understand how that guy finds the time to do interesting things all the time. | 08:06 |
| Joelw | Yep, I found all of your Python stuff - looks very interesting, but a bit foreign to me (but even Verilog does now that I haven't touched it for three years) | 08:07 |

| tumbleweed | mithro: there? | 08:37 |

| tumbleweed | it seems that way on the working ones too | 10:20 |
| tumbleweed | mithro: and the fbga seems to be behaving just fine | 10:28 |
| mithro | tumbleweed: that is very weird | 10:58 |

| tumbleweed | no, but I can | 11:01 |
| tumbleweed | one sec, lunch | 11:04 |
| tumbleweed | right | 11:16 |
| tumbleweed | jumpered with out P18, and with K3 on 1-2 | 11:18 |
| tumbleweed | I measure 3.07v at R72 | 11:19 |
| tumbleweed | that's with a normal firmware | 11:19 |
| tumbleweed | mithro: ^^ | 11:20 |
| olasd | that's in tolerance for the FX2; a bit on the low side but should be fine | 11:22 |

| Joelw | mithro: What's in this EDID blob? https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/gateware/hdmi_in/edid.py Is it something that advertises Spartan-6 friendly resolutions? | 12:34 |
