| tumbleweed | apt had solved a dependency problem by using sid's openocd | 00:00 |
|---|---|---|
| tumbleweed | (which is newer) | 00:00 |
| CarlFK | lol | 00:00 |
| CarlFK | the problem is you are using my packaging :p | 00:01 |
| tumbleweed | now I get: | 00:03 |
| tumbleweed | Error: unable to open ftdi device: device not found | 00:03 |
| CarlFK | power cycle the atlys | 00:06 |
| CarlFK | a udev rule should auto load something | 00:06 |
| CarlFK | that makes lusb show: | 00:06 |
| CarlFK | Bus 002 Device 015: ID 16c0:06ad Van Ooijen Technische Informatica | 00:06 |
| CarlFK | Bus 005 Device 004: ID 04e2:1410 Exar Corp. | 00:06 |
| tumbleweed | where do you get that udev rule? | 00:07 |
| CarlFK | um.. one of my apt-gets from notes.txt | 00:07 |
| tumbleweed | I have the Exar Corp device, and a Digilent Development board JTAG device | 00:07 |
| CarlFK | ixo-usb-jtag | 00:08 |
| tumbleweed | yeah, I just figured that out :) | 00:08 |
| mithro | tumbleweed: don't use Carl's openocd package :-) | 00:10 |
| tumbleweed | much better :) | 00:10 |
| tumbleweed | mithro: what should I use? | 00:10 |
| mithro | tumbleweed: the firmware will download openocd from conda | 00:10 |
| tumbleweed | "the firmware" ? | 00:11 |
| mithro | The get-env scripts | 00:11 |
| tumbleweed | those sound like things I want to run, a lot less than carl's packages | 00:11 |
| mithro | Yes | 00:12 |
| tumbleweed | the packages may be messy, but at least I know what they're doing | 00:12 |
| tumbleweed | and it looks like the messyness will resolve (one way or another) | 00:12 |
| mithro | CarlFK's instructions are not useful if you want to actually help with development or do anything apart from basic testing | 00:13 |
| tumbleweed | that's fine. I don't want to be installing proprietary crap on my laptop | 00:13 |
| tumbleweed | getting it working at all is the most useful thing for me to do now | 00:13 |
| mithro | https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/scripts/README.md | 00:13 |
| tpb | Title: HDMI2USB-misoc-firmware/README.md at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 00:13 |
| mithro | Love some help making those work on Debian | 00:14 |
| mithro | I'll be back in about 30 minutes | 00:15 |
| tumbleweed | I think I'll scare Debian Video people off a lot more with "install a proprietary development environment" than: "here are some messy debs that'll make it work" | 00:15 |
| mithro | Just getting up and heading to work | 00:15 |
| tumbleweed | I'm pretty sure we can make the production setup of this on Debian nice and simple | 00:15 |
| tumbleweed | dev is probably a lot harder (due to the Xilinx ISE) | 00:16 |
| mithro | tumbleweed: the production setup should be just install HDMI2USB-mode-switch | 00:16 |
| mithro | tumbleweed: but that needs packaging | 00:17 |
| tumbleweed | well, the production setup should be "turn it on" :P (eventually) | 00:17 |
| mithro | Yes, true | 00:17 |
| tumbleweed | anyway, it works | 00:17 |
| mithro | Mode-switch will be needed if you want to upgrade the firmware | 00:17 |
| mithro | If you wanted to be really fancy, you could have the gateware binary and the lm32 headers packaged, then people could still work on the lm32 firmware (which is just C) without needing the proprietary toolchain | 00:30 |
| tumbleweed | that sounds useful | 00:31 |
| mithro | tumbleweed: do you know udev at all? | 00:34 |
| mithro | I'd like to setup /dev/hdmi/<serial number>/{video,tty} symlinks | 00:35 |
| tumbleweed | only very vaguely | 00:43 |
| tumbleweed | CarlFK: did you find any VGA->HDMI convertors that work, yet? | 00:43 |
| tumbleweed | I got a couple to try, but they don't provide the right modes by EDID | 00:44 |
| CarlFK | tumbleweed: other than the one I got a year ago, I havent tried | 00:44 |
| tumbleweed | this does 1080p, but not 720p http://amazon.com/gp/product/B00Y3IGB62 | 00:45 |
| CarlFK | my current plan for Node: if your laptop doesn't do hdmi, you get the twinpact. | 00:46 |
| CarlFK | the two rooms we are in only have vga to the projector | 00:47 |
| CarlFK | and I am not inclined to rewire them | 00:47 |
| tumbleweed | that means you need working HDMI->VGA | 00:48 |
| tumbleweed | do we have that? | 00:48 |
| CarlFK | I think so.. I need to make sure I have 2 | 00:53 |
| CarlFK | or just get 2 more. they are cheep.. $15 ish | 00:53 |

| CarlFK | mithro: pong | 01:58 |
| mithro | CarlFK: on that fresh setup, can you do a "conda update openocd" and then try "make load-gateware" step again? | 01:59 |
| CarlFK | mithro: sure. | 01:59 |
| CarlFK | works | 02:10 |
| CarlFK | and I confirmed that it didn't work before the "conda update openocd" | 02:11 |
| CarlFK | mithro: ^^^ | 02:12 |
| mithro | okay, great - can you try from scratch again? | 02:12 |
| mithro | CarlFK: A while back I asked if you wanted to manage the stable/testing links in the prebuilt repo | 02:12 |

| mithro | CarlFK: can you resend that to the timvideos repo? | 02:32 |
| CarlFK | because thats what I tested | 02:32 |
| CarlFK | I have no idea how to send that somewhere else | 02:33 |

| mithro | _florent_: you about? I now have a pretty good understanding of how the USB needs to work (IE What needs to happen on the FX2 and signals the gateware needs to send) but I'm unsure on the correct way to implement it | 10:33 |
| mithro | _florent_: basic theory is that the LM32 needs to generate a header, set a couple of bits and then DMA out the header+encoder data following it (and stalling on a FIFO full bit) | 10:43 |

| _florent_ | hi mithro, sorry I don't understand what you are doing exactly: why do we need to change the way the USB works? | 11:42 |
| mithro | _florent_: because I'd like to decouple the USB and the JPEG parts and move the USB stuff into migen/misoc | 11:44 |
| _florent_ | ah OK, | 11:44 |

| _florent_ | so moving code from the FX2 to the gateware? | 11:45 |
| mithro | _florent_: Well, the gateware / lm32 firmware needs to eventually send configuration information over to the FX2 (IE the resolutions) | 11:47 |
| _florent_ | ok | 11:48 |
| mithro | so, I've been rewriting almost all of the FX2 firmware to be more understandable | 11:49 |
| mithro | https://docs.google.com/document/d/15oMrgGfgziHL9kqiRNEF34UaUKkOw0XkG7-D83iEM1s/edit# | 11:49 |
| tpb | Title: Google Docs - create and edit documents online, for free. (at docs.google.com) | 11:49 |
| _florent_ | so we should change the usb streamer and add a ram to it that will contain the header and for each JPEG frame, send the header first followed by the frame | 11:49 |
| mithro | _florent_: yes, the FX2 will act pretty much like a FIFO | 11:50 |
| mithro | _florent_: you just keep sending bytes until the "FIFO full flag" is raised | 11:50 |
| mithro | _florent_: then you pause until it is deasserted | 11:50 |
| _florent_ | ok, that seems easier indeed | 11:51 |
| mithro | _florent_: when you finish sending a full frame, you then toggle the "packet end" signal | 11:51 |
| _florent_ | yes that seems fine | 11:52 |

| *** travis-ci has left #timvideos | 11:52 | |
| mithro | _florent_: I was really hoping to figure out a way to put the other end points under the LM32 control as the FX2 is super sucky - but it isn't really possible | 11:53 |
| mithro | _florent_: Getting the CDC port working again is pretty simple too. | 11:53 |
| mithro | _florent_: there are two endpoints, one you write data to | 11:54 |
| mithro | _florent_: the other you read data from | 11:54 |
| mithro | _florent_: the FIFOADDR[1.0] pins control which endpoint the fifo interface is connected too | 11:54 |
| _florent_ | ok, for now you are emulating an UART with the FX2? | 11:55 |
| mithro | _florent_: yeah - but that only works on the opsis | 11:56 |
| mithro | _florent_: Sadly, the hardware UARTs arn't exposed on the FX2 onboard the Atlys | 11:57 |
| mithro | _florent_: so, the process for sending a UART byte, is to interrupt the pending video data being sent, setting the FIFO address pins, writing the UART bytes, toggling pktend, restoring the FIFO address pins and allowing the video the continue where it left off | 11:59 |
| _florent_ | ok | 12:00 |
| mithro | _florent_: but for now we can ignore that | 12:01 |

| mithro | _florent_: I might just do software bit-banging at 9600 board or something on the spare pins | 12:03 |
| mithro | s/board/baud/ | 12:11 |
| mithro | _florent_: What I also wanted to mention is that I've been working on some FX2 firmware which makes it emulate a FTDI 232H chip as a better replacement for ixo-usb-jtag - I figured that might mean it would work pretty well with your liteUSB stuff | 12:12 |
| _florent_ | ah ok, then we will be able to share code between liteUSB and the HDMI2USB gateware | 12:15 |
| mithro | _florent_: yeah - this is more to make the Opsis more compatible with xc3sprogs and a bunch of proprietary JTAG tools under Windows / Mac | 12:17 |
