mithrocr1901_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 input00:44
mithro_florent_ / cr1901_modern: What do you use for gcc/binutils/openocd under Windows?00:44
cr1901_modernmithro: 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_modernFor 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_modernThe 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_output00:49
cr1901_modernSo I have to run it through a utility called "cygdrive" to convert the POSIX path to something Windows won't choke on00:50
cr1901_modernpyserial.miniterm is missing the console export on Windows, and _florent_ doesn't remember how he solved this problem lol00:52
shenkiuse linux?00:53
cr1901_modernshenki: No. I'm not having this discussion.00:54

mithroCarlFK: you need to put the Opsis into JTAG mode first01:07
CarlFKmithro: how?01:07
CarlFKolasd: you figured this out, right?01:07
mithroCarlFK: 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 fxload01:08
mithroAs I think I mentioned multiple times01:10
CarlFKmithro: so this?  (HDMI2USB) [email protected]:~/HDMI2USB-mode-switch$ ./update-fx2-firmware.sh01:12
mithroCarlFK: no01:13
mithroThat updates the fx2 firmware in the repository01:13
mithroCarlFK: are you on my opsis-prod branch?01:13
tpbTitle: GitHub - mithro/HDMI2USB-mode-switch at opsis-prod (at github.com)01:13
CarlFK(HDMI2USB) [email protected]:~/HDMI2USB-mode-switch$ git checkout opsis-prod01:14
CarlFKI see a few likely shell scripts...01:14
CarlFKopsis-flash.sh  opsis-update.sh01:15
mithroCarlFK: opsis-update.sh is probably what you want01:15
CarlFKPermissionError: [Errno 13] Permission denied: '/sys/bus/usb/devices/2-1.1:1.0/driver/unbind'01:16
mithroCarlFK: that means you haven't setup the environment01:16
mithroCarlFK: see the opsis-setup.sh01:17
mithroCarlFK: I've pointed you at this stuff before01:19
CarlFK(HDMI2USB) [email protected]:~/HDMI2USB-mode-switch$ ./opsis-update.sh01:21
CarlFKnow I have a bunch of Numato Opsis in 'jtag' mode at /dev/bus/usb/002/01101:22
tpbTitle: Ubuntu Pastebin (at paste.ubuntu.com)01:22
CarlFKis that expected?01:22
CarlFKor should I care ?01:22
cr1901_modernLooks like it's running detection repeatedly?01:23
cr1901_modernI'm guessing Opsis uses FT2232 like most boards, so seeing two of them is expected.01:24
mithrocr1901_modern: the Opsis does *not* use a FT223201:39
mithroCarlFK: that looks as expected01:39
mithrowell expect your weird wrapping01:39
cr1901_modernAhhh, I stand corrected01:40
CarlFKmithro: now I do make flash?01:56
mithroCarlFK: yes01:56
mithroyou can check lsusb to see if you have the opsis in jtag mode01:56
CarlFKBus 002 Device 011: ID 16c0:06ad Van Ooijen Technische Informatica01:56

mithroCarlFK: power cycle and try again02:00
CarlFKmithro: pulled both power and usb for 5 seconds, lsusb still shows02:02
CarlFKBus 002 Device 019: ID 16c0:06ad Van Ooijen Technische Informatica02:03
mithroCarlFK: do you have multiple boards connected to the machine at once?02:03
mithroCarlFK: It can take about ~15 seconds for the power to cycle02:04
CarlFKk - unpugged02:04
CarlFKplugged in 60+ seconds later, still Bus 002 Device 023: ID 16c0:06ad Van Ooijen Technische Informatica02:06
CarlFKhitting the reset button may have done it:02:09
CarlFKBus 002 Device 024: ID 2a19:544202:09
mithroCarlFK: hrm02:09
mithroCarlFK: The FX2 should power off when you disconnect the power02:09
mithroCarlFK: what were the LEDs doing?02:10
CarlFKmithro: um... I didn't take the lid off the box till I hit the reset02:14
CarlFKmithro: ./opsis-update.sh  .... make flash ....02:21
CarlFKWarn : Bypassing JTAG setup events due to errors02:21
CarlFKError: Unknown flash device (ID 0x00818181)02:21
mithroCarlFK: What is your jumper config? Have you been playing with them?02:21
mithroCarlFK: the 818181 stuff generally means that getting isn't jtag mode didn't go correctly02:22
mithrobut it doesn't normally appear in the location you are getting it02:22
CarlFKmithro: I seem to remember playing with jumpers the last time we were tying to do this02:23
mithroCarlFK: and you didn't put them back in the locations they started?02:23
CarlFKdon't know.02:23
CarlFKmithro: there should be some docs on how they should be delivered, right ?02:24
mithroCarlFK: If someone had time to write them02:29
CarlFKanyone in here have an Opsis board ?02:46

CarlFKmithro: so what next?03:10
mithroCarlFK: Figure out why you have borked stuff :P03:26
CarlFKmithro: I think you need to get your hand on an Opsis so we can see what working looks like03:57
mithroCarlFK: olasd was able to get it working on the Opsis he was testing with03:58
CarlFKok, get his board ;)03:58
CarlFKmithro: any other ideas?  if not, I'll pack up and go home04:05

CarlFKsomeone is at least talking about laying out the traces for tofe05:30
rohitksinghCarlFK: haven't worked on that in last 4 days. down with fever :/05:31
CarlFKyuck.   hope you are feeling better soon05:31
rohitksinghCarlFK: yeah. and how are you?05:32
CarlFKok - stayed up too late last night, and it is 30 past midnight, so about to fall asleep05:34
CarlFKbut I am trying to figure out how to install xenial using my preseed install, which somehow can't figure out what device to install to05:35
rohitksinghCarlFK: oh, I forgot it must be late night there! you should probably sleep now05:35
CarlFKlol - yep05:35

Neuron1kHi 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
Neuron1kAlso 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.html10:35

shenkiNeuron1k: hello10:50
_florent_Hi Neuron1k, litejpeg repo was prepared for GSoC11:05
_florent_that's just a skeleton for you with some things that are initiated11:05
_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 existing11:07

Neuron1kOk, thank you for the fast answer. I must say that this skeleton gives good insight and is really comprehensive :)11:29
