| *** tija has joined #timvideos | 06:15 | |
| tija | I wrote a blog on remote access of fpga. It seems IIT,Delhi have already created something similar. Unfortunately it is not opensourced. http://iitd.vlab.co.in/?sub=66&brch=184 | 06:16 |
| tpb | Title: FPGA & Digital Design Lab : Computer Science & Engineering : IIT DELHI Virtual Lab (at iitd.vlab.co.in) | 06:16 |
| shenki | tija: cool | 06:17 |
| shenki | tija: if you were to create a system for using a FPGA remotely, what would it look like? | 06:18 |
| shenki | i guess you'd want a way of reserving/locking access to the board | 06:19 |
| shenki | a way to power cycle | 06:19 |
| shenki | access to GPIOs | 06:19 |
| shenki | framegrabbing of the HDMI output | 06:19 |
| shenki | USB progrogramming, USB for UART debug | 06:19 |
| shenki | LED/status indicator output | 06:20 |
| shenki | i wonder if you could build something by connecting a board to a raspi | 06:22 |
| tija | shenki: Power cycle and locking the board access would be the complex part. Other than that almost everything is done. Take the bit stream and scp over to the remote computer. Fire a script to dump the bit stream, the use control ports to change the HDMI channels, record the HDMI out and debug data and send it back. | 06:23 |
| mithro | tija: you'd want a camera pointed at the board as well I think | 06:23 |
| shenki | mithro: what would it be looking for? | 06:23 |
| shenki | smoke? :D | 06:23 |
| mithro | LEDs | 06:23 |
| tija | not necessary the all the LEDS status can be seen using the control ports. | 06:24 |
| shenki | mithro: yeah, i'd wire up the LEDs (or just a bank of GPIO) to the Raspi, and have them viewable on a web UI | 06:26 |
| mithro | shenki: that is one option - but it means you can use "stock" dev boards | 06:26 |
| shenki | same with the GPIO: make them "pressable" using a web ui from the raspi | 06:26 |
| shenki | true | 06:26 |
| mithro | shenki: if you wanted to make a "remote accessible dev board" from scratch its much easier | 06:26 |
| shenki | you could use a stock board; they have headers that can be wired as GPIO | 06:27 |
| mithro | tija: If you come up with a design that works, I'm happy to build / deploy / fund it | 06:27 |
| shenki | tija: we have a django based tool we use internally called hostlocker | 06:27 |
| shenki | tija: it lists the machines, and lets you 'lock' them | 06:28 |
| tija | Yeah sure. If we can make this and then opensource it will be a high impact project. A country like India needs this kind of frame work. | 06:28 |
| shenki | i will ask the guy who maintains it if he wants to open source it | 06:28 |
| mithro | be back in 30 minutes | 06:28 |
| shenki | tija: not just india. i remember doing projects with a uni in Californa who had a remoted access FPGA that was shared by the class | 06:28 |
| tija | shenki: powering on the fpga will be tricky. | 06:29 |
| shenki | tija: depends on your budget :) you could buy a controllable power switch and use a GPIO from the raspi | 06:30 |
| shenki | http://postscapes.com/smart-outlets | 06:31 |

| shenki | im sure deal extreme has cheaper ones | 06:31 |
| tija | oh interesting! Didn't knew something like this existed. | 06:32 |
| mithro | The hard part is the arbitrating access | 06:35 |
| mithro | Specially when this thing ends up with like 20 USB devices | 06:36 |
| mithro | I've always had an idea for a smart USB hub to manage this | 06:39 |
| *** Niharika has quit IRC | 06:42 | |
| shenki | mithro: "this thing ends up with like 20 USB devices" which thing? | 06:45 |
| shenki | mithro: ive been playing with cloudflare on jms.id.au | 06:49 |
| shenki | mithro: unfortunatly it doesn't work at the moment, as it fails to establish a ssl connection between cloudflare and hopper | 06:50 |
| shenki | mithro: i wonder if it detected the serial number issue and got confused? | 06:50 |
| mithro | shenki: When you end up having the host managing like 10 FPGA dev boards which each have a USB camera, usb programming, usb debug, etc | 06:53 |
| shenki | mithro: yeah, that would get hectic | 06:56 |
| shenki | mithro: i think you'd have a 1-1 relationship between a FPGA board and a raspi | 06:56 |
| shenki | mithro: and then arbitrate the access to a 'dev unit' - a raspi+fpga dev board - through some central host | 06:56 |
| mithro | shenki: then you get to manage 10+ raspi machines :P | 07:00 |
| mithro | shenki: I'm wondering a VM type solution where you plumb the USB device into the VM | 07:00 |
| mithro | much easier to do "throw away" stuff with VMs | 07:02 |

| shenki | mithro: you need hardware I/O for talking to the fpga | 07:08 |
| shenki | mithro: manage the 10+ raspi by netbooting them | 07:08 |
| shenki | dhcp to assign IPs | 07:08 |
| shenki | assosciate raspi MAC with FPGAs | 07:08 |
| * shenki wants to implement this now | 07:09 | |
| tija | mithro: haha! It is true that we have a lot of applicants. I know a guy who got accepted from 3 different orgs. And a guy who put 4 proposals but couldn't get selected | 07:09 |
| shenki | tija: how many students are studying engineering at your uni? | 07:10 |
| tija | There are 200 in my batch | 07:10 |
| shenki | tija: you should re-publish their blogpost with the numbers normalised agaisnt things like the country size, and or the number of engineering graduates from the uni that yaer | 07:10 |
| shenki | Computer Science and other technical fields | 07:11 |
| shenki | that's very ...broad | 07:11 |
| shenki | i wonder what the other fields were? | 07:11 |
| mithro | shenki: engineering and mathmatics would be my guess? | 07:12 |
| shenki | were they all elec eng, or did they manange to recurit some non-coding people like chem or mechengies | 07:12 |
| shenki | mithro: yeah | 07:12 |
| tija | shenki: China has in total 49 selections. | 07:12 |
| shenki | mithro: you'd think an engineering company would come out with some better statistical analysis | 07:12 |
| shenki | tija: yeah, i wonder why that is? | 07:12 |
| tija | mithro: My college has just two branches CSE and ECE that's it | 07:13 |

| rohitksingh | mithro: great! To visit abroad, first I'll have to apply for a passport, which I don;t have yet! :) | 08:55 |
| mithro | rohitksingh: is cost the only reason you might not be able to attend? Or does it conflict with school work and such? | 08:57 |
| *** slomo has quit IRC | 09:02 | |
| rohitksingh | mithro: It will most probably not conflict with college, as during that time classes would be few. My major concern is GATE examination which is common entrance exam for admission for Masters degree into top-most colleges of India (IITs and IISc). It falls b/w 31st January to 14th February. I think my preparations might suffer. ( http://awesomescreenshot.com/06d3m2h28b ) | 09:08 |
| rohitksingh | mithro: One more thing I wanted to ask. I was planning to implement a framebuffer for VGA and did some rudimentary coding + simulation on that. I was thinking of using your tripler-buffer arbiter code which you wrote sometime back. Whats your opinion? | 09:08 |

| mithro | My guess is it's the chip under the white sticker on the front | 13:50 |
| mithro | rohitksingh: do you want to take a look at tija's link and see if you can guess the chip under the white sticker? | 13:51 |
| rohitksingh | :D I was checking that link itself! | 13:52 |
| mithro | ahh | 13:53 |
| mithro | After we have started this kickstarter project it was brought to our attention, that the Broadcom BCM2835 processor is only designed to take the video input from an image sensor as used on the camera board. The integrated video processor in the BCM2835 performs video processing functions specifically for these type of sensors, to create a clean video. The | 13:53 |
| mithro | HDMI input chip already creates a clean video. As the video processing for the camera cannot be disabled at this time, a clean video cannot be interfaced to the serial camera interface (the MIPI/CSI connector). This is a show stopper. | 13:53 |

| mithro | CarlFK: audio is a bit weird | 14:25 |
| CarlFK | ganky PA on left, camera mic on right | 14:26 |
| CarlFK | ganky PA is some low budget thing built into the podium | 14:26 |
| CarlFK | and no one is really talking into the mic, which isn't truned up much | 14:27 |
| mithro | CarlFK: you can use the left/right hack I used in flumotion in your gstreamer to youtube pipeline if you want to fix that | 14:29 |
| mithro | CarlFK: also very quiet | 14:29 |
| CarlFK | mithro: once again, I think it would have been less work for me to bring/use my own mics | 14:32 |
| CarlFK | I may just do that tomorrow. | 14:32 |
| CarlFK | for the 6 talks :p | 14:32 |
| aps | CarlFK: i think you should use volume element in pipeline | 14:33 |
| aps | It's very low | 14:33 |
| mithro | CarlFK: and its frozen? | 14:35 |
| CarlFK | let me bring up a 2nd stream to play with | 14:35 |
| CarlFK | oh hell my bash while true loop isn't right | 14:35 |

| *** rohitksingh has joined #timvideos | 14:36 | |
| aps | mithro: should we create a rmtp/YouTube Flumotion component using this pipeline Carl is using? | 14:37 |
| mithro | CarlFK: you just started streaming your old thing to the same location? | 14:37 |
| CarlFK | mithro: click "* live" | 14:38 |
| CarlFK | i hope. | 14:38 |
| mithro | hrm... | 14:38 |
| mithro | yeah that fixed it | 14:38 |
| CarlFK | yay, first confirmation :D | 14:38 |
| mithro | but I just had it going in the background and it flicked to that bit | 14:38 |
| rohitksingh | mithro: Can't figure out which IC it is. Definitely not a regular Analog Devices one. even QR code decoding failed. Google search doesn't reveal any QFP80 package HDMI receiver IC. Also, the guys have been careful to not name the IC anywhere | 14:39 |
| rohitksingh | seems either ASIC by some company or some less popular company | 14:40 |

| CarlFK | the gs pipeline exits now and thsn | 14:47 |
| CarlFK | like just now | 14:47 |
| rohitksingh | mithro: I can see live stream. Some lady is speaking. audio fine. video slightly out-of-focus (maybe because I'm viewing at 240p?) | 14:48 |
| rohitksingh | now video is good | 14:49 |
| mithro | CarlFK: is it segfaulting? | 14:49 |
| mithro | CarlFK: IE, why is it exiting? | 14:50 |
| CarlFK | would there be something in dmesg? | 14:51 |
| thaytan | CarlFK, if it's segfaulting there would | 14:52 |
| thaytan | otherwise there might be messages on the gstreamer bus | 14:52 |
| thaytan | you can run with GST_DEBUG=3 to see warnings and errors | 14:52 |
| thaytan | but possibly network connection dropouts and not reconnecting? | 14:53 |
| mithro | thaytan: my guess is that CarlFK is using sadly using gst0.10 | 14:54 |
| CarlFK | I am | 14:54 |
| thaytan | it's OK, there there, etc | 14:54 |
| CarlFK | http://paste.ubuntu.com/8515027/ why doesn't that loop? | 14:54 |

| thaytan | mithro, ahr | 15:06 |

| Kripton | Hi rohitksingh, the IC you found doesn't actually seem to be expensive: http://www.aliexpress.com/item/EP9351-QFP-64-IC-Free-shipping/1925882945.html | 20:43 |
| tpb | Title: EP9351 QFP 64 IC Free shipping-in Integrated Circuits from Electronic Components & Supplies on Aliexpress.com | Alibaba Group (at www.aliexpress.com) | 20:43 |
| Kripton | not cheap though but not as expensive as an FPGA board. However, of course not open-source and not extensible in the future | 20:43 |
| rohitksingh | Kripton: I searched for it too in Alibaba. But seems the link is for different IC(?) as the it should have QFP80 package as opposed to QFP64 | 20:45 |
| Kripton | rohitksingh, oh, I didn't actually verify that | 20:46 |
| rohitksingh | but the pictures in above link is of QFP80! intriguing! and the test says QFP64 | 20:47 |
| rohitksingh | *text | 20:48 |
| rohitksingh | Kripton: Anyway, if it really is EP9351, then it will be QFP80. BTW i found its reference code + rudimentary datasheet today. Let me search again | 20:49 |
| rohitksingh | Here: 61.222.141.234/EP905Firmware/EP905Firmware.htm and wenku.baidu.com/view/006f8a19fc4ffe473368ab0f.html | 20:49 |
