| mithro | cr1901_modern: The key thing I'm after is working out how to use Hamster's "high frequency counter" with the clock lines of the HDMI input | 00:44 |
|---|---|---|
| mithro | _florent_ / cr1901_modern: What do you use for gcc/binutils/openocd under Windows? | 00:44 |
| cr1901_modern | mithro: All of those utils work fine under Windows. It's that Windows isn't POSIXy that's the source of most of my problems. | 00:47 |
| cr1901_modern | For example, the flash target doesn't work unless I make a change to the openOCD builder in Migen to escape backslashes, since POSIX forbids this, but Windows is okay with backslashes in paths (and expects it!) | 00:48 |
| cr1901_modern | The git_info peripheral in HDMI2USB has a similar problem, where git rev-parse will return a POSIXy path that Windows python cannot handle in the "cwd" argument for subprocess.check_output | 00:49 |
| cr1901_modern | So I have to run it through a utility called "cygdrive" to convert the POSIX path to something Windows won't choke on | 00:50 |
| cr1901_modern | cygpath* | 00:50 |
| cr1901_modern | pyserial.miniterm is missing the console export on Windows, and _florent_ doesn't remember how he solved this problem lol | 00:52 |
| shenki | use linux? | 00:53 |
| cr1901_modern | shenki: No. I'm not having this discussion. | 00:54 |

| mithro | CarlFK: you need to put the Opsis into JTAG mode first | 01:07 |
| CarlFK | mithro: how? | 01:07 |
| CarlFK | olasd: you figured this out, right? | 01:07 |
| mithro | CarlFK: Well the "debug fx2_reboot usb_jtag" thingy doesn't work on your current firmware, so you have to use mode-switch or manually use fxload | 01:08 |
| mithro | As I think I mentioned multiple times | 01:10 |
| CarlFK | mithro: so this? (HDMI2USB) juser@dc10b:~/HDMI2USB-mode-switch$ ./update-fx2-firmware.sh | 01:12 |
| mithro | CarlFK: no | 01:13 |
| mithro | That updates the fx2 firmware in the repository | 01:13 |
| mithro | CarlFK: are you on my opsis-prod branch? | 01:13 |

| CarlFK | (HDMI2USB) juser@dc10b:~/HDMI2USB-mode-switch$ git checkout opsis-prod | 01:14 |
| CarlFK | I see a few likely shell scripts... | 01:14 |
| CarlFK | opsis-flash.sh opsis-update.sh | 01:15 |
| mithro | CarlFK: opsis-update.sh is probably what you want | 01:15 |
| CarlFK | PermissionError: [Errno 13] Permission denied: '/sys/bus/usb/devices/2-1.1:1.0/driver/unbind' | 01:16 |
| CarlFK | sudo? | 01:16 |
| mithro | CarlFK: that means you haven't setup the environment | 01:16 |
| mithro | CarlFK: see the opsis-setup.sh | 01:17 |
| mithro | CarlFK: I've pointed you at this stuff before | 01:19 |
| CarlFK | (HDMI2USB) juser@dc10b:~/HDMI2USB-mode-switch$ ./opsis-update.sh | 01:21 |
| CarlFK | now I have a bunch of Numato Opsis in 'jtag' mode at /dev/bus/usb/002/011 | 01:22 |
| CarlFK | http://paste.ubuntu.com/16197524/ | 01:22 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 01:22 |
| CarlFK | is that expected? | 01:22 |
| CarlFK | or should I care ? | 01:22 |
| cr1901_modern | Looks like it's running detection repeatedly? | 01:23 |
| cr1901_modern | I'm guessing Opsis uses FT2232 like most boards, so seeing two of them is expected. | 01:24 |
| mithro | cr1901_modern: the Opsis does *not* use a FT2232 | 01:39 |
| mithro | CarlFK: that looks as expected | 01:39 |
| mithro | well expect your weird wrapping | 01:39 |
| cr1901_modern | Ahhh, I stand corrected | 01:40 |
| CarlFK | mithro: now I do make flash? | 01:56 |
| mithro | CarlFK: yes | 01:56 |
| mithro | you can check lsusb to see if you have the opsis in jtag mode | 01:56 |

| CarlFK | Bus 002 Device 019: ID 16c0:06ad Van Ooijen Technische Informatica | 02:03 |
| mithro | CarlFK: do you have multiple boards connected to the machine at once? | 02:03 |

| mithro | CarlFK: what were the LEDs doing? | 02:10 |
| CarlFK | mithro: um... I didn't take the lid off the box till I hit the reset | 02:14 |

| mithro | CarlFK: What is your jumper config? Have you been playing with them? | 02:21 |
| mithro | CarlFK: the 818181 stuff generally means that getting isn't jtag mode didn't go correctly | 02:22 |
| mithro | but it doesn't normally appear in the location you are getting it | 02:22 |
| CarlFK | mithro: I seem to remember playing with jumpers the last time we were tying to do this | 02:23 |
| mithro | CarlFK: and you didn't put them back in the locations they started? | 02:23 |
| CarlFK | don't know. | 02:23 |
| CarlFK | mithro: there should be some docs on how they should be delivered, right ? | 02:24 |
| mithro | CarlFK: If someone had time to write them | 02:29 |
| CarlFK | anyone in here have an Opsis board ? | 02:46 |

| Neuron1k | Hi guys! I have question to mithro and _florent_ about litejpeg repo. There is already some code that covers my GSoC proposal schedule. I have impression that _florent_ is making continuous effort to make entire encoder works. So what will be left for me? ;) | 10:32 |
| Neuron1k | Also I have qustion about some python library that is similar to maltab fixed point toolbox, do you know any? I have found http://www.dilloneng.com/demodel.html | 10:35 |

| shenki | Neuron1k: hello | 10:50 |
| _florent_ | Hi Neuron1k, litejpeg repo was prepared for GSoC | 11:05 |
| _florent_ | that's just a skeleton for you with some things that are initiated | 11:05 |
| _florent_ | I just prepared some things so tht you see how we want things to be tested/integrated, but I'm not working on it and that now your turn :) | 11:07 |
| _florent_ | The things that are initiated are the one that were easy to do or already existing | 11:07 |
| *** micolous_ has quit IRC | 11:21 | |

| Neuron1k | Ok, thank you for the fast answer. I must say that this skeleton gives good insight and is really comprehensive :) | 11:29 |
