mithroBTW What timezone is RattusRattus in?00:17
CarlFKmithro: RattusRattus UK I think00:17
CarlFKmithro: v0.0.2-41-g00d86be ... loaded, dmesg [189841.780896] vizzini 1-2:1.0: ttyVIZ0: XR21v14x usb uart device00:21
CarlFKflterm connects, but enter = nothing00:21
*** sb0 has joined #timvideos00:24
CarlFKwent back to v0.0.2-61-ga02ee1a, it connects.  good. worried bord was bricked00:32
CarlFKhmm, may have spoke too soon.  BIOS> romboot ...  screen of ver info, but no prompt00:33
CarlFKv0.0.0-639-g956a8b3-dirty works.  good.00:49
mithroCarlFK: Figuring out when things went "bad" is good01:18
CarlFKmithro: well, I am getting inconsistent results01:19
mithroCarlFK: inconsistent in what way?01:19
CarlFKmithro: loaded v0.0.2-41-g00d86be , seemed to have loaded ok, but no stream and flterm connects but nothing comes back when I hit enter01:23
mithroCarlFK: Try hitting the red reset button?01:23
CarlFKloaded another version, it worked, loaded v0.0.2-41-g00d86be again, now it works01:24
mithrobe back maybe - helping ryan pack the car01:27
CarlFKunderstood01:27
mithroCarlFK: that is very weird01:41
mithroCarlFK: how are you loading things?01:41
CarlFKmithro: http://paste.ubuntu.com/22981095/  or... hdmi2usb-mode-switch --mode=jtag ... openocd ... fxload ... flterm01:43
tpbTitle: Ubuntu Pastebin (at paste.ubuntu.com)01:43
CarlFKmithro: I normally don't see the lines 12-35 of Info : TAP auto0.tap does not have IDCODE01:44
mithroCarlFK: if you see the IDCODE problem - you need to reset the board and switch to jtag mode again01:49
CarlFKmithro: k01:49
mithroCarlFK: "Warn : Bypassing JTAG setup events due to errors" <-- Nothing was flashed01:50
mithroCarlFK: heading out on the road, may or may not be around01:51
CarlFKk01:51
mithroCarlFK: it would probably be good to start using "hdmi2usb-mode-switch --load-gateware=<blah>" and "hdmi2usb-mode-switch --load-fx2=<blah>"02:04
mithroCarlFK: It will eventually check / work around issues like that02:07
CarlFKmithro: why does it add a /firmware/ dir?02:49
CarlFK[email protected]:~/HDMI2USB-firmware-prebuilt/archive/master/v0.0.2-36-g585a9e2/atlys/hdmi2usb# hdmi2usb-mode-switch --load-fx2=hdmi2usb.hex02:49
CarlFKAssertionError: /home/juser/.virtualenvs/veyepar/lib/python3.5/site-packages/hdmi2usb.modeswitch-0.0.0+86.g00dba4f-py3.5.egg/hdmi2usb/firmware/hdmi2usb.hex02:49
CarlFKhdmi2usb-mode-switch --load-fx2=$PWD/hdmi2usb.hex02:50
CarlFKthat works.02:50
mithroCarlFK: give it an absolute path if you don't want to load an inbuilt firmware02:51
CarlFKmithro: what is "inbuilt" ?02:52
mithroCarlFK: jtag/serial02:52
mithroeeprom shortly02:53
CarlFKmithro: how/why did you make a --option that doesn't show up in --help?02:55
mithroCarlFK: which ones?02:56
CarlFK--load-fx202:56
CarlFKthere is --load-fx2-firmware .. does it accept ... um.. only as much as needed?02:57
mithroCarlFK: Hrm, you might be right02:57
mithrobblr02:57
mithroarriving at venue02:58
CarlFKgood luck!02:58

mithrohey ssk1328 - How goes things today?06:32
ssk1328mithro: Just replying to your mail06:32
ssk1328mithro: Just sending reply!06:32
mithrossk1328: Thanks!06:32
ssk1328mithro: Sent!06:33
ssk1328mithro: What time are you around today?06:36
mithrossk1328: Probably in the evening06:36
ssk1328mithro: Okay06:37
mithrossk1328: I'm a bit in and out now, so please do just talk into the channel about the issues you are having and I'll try and respond as much as possible06:37
ssk1328mithro: Okay06:37
ssk1328mithro: I have trouble creating iterable variable names for CSR registers06:38
mithrossk1328: Hrm?06:38
ssk1328mithro: Migen simple says CSR variable name can't be supplied from code06:39
mithrossk1328: you can provide a name using "name=xx" argument I believe06:39
ssk1328mithro: Is this equivalent to self.name = CSRStorage(16, reset=0)06:40
mithrossk1328: self.xxxx = CSRStorage   ====  CSRStorage(xxxxx, name="xxxx")   I believe06:41
ssk1328mithro: Okay06:42
mithrossk1328: I still think you need to assign the CSRStorage somewhere06:43
mithrodoes setattr(self, "xxxx", CSRStorage(blah)) work?06:43
ssk1328mithro: No setattr doesn't work06:44
ssk1328mithro: Neither does a list or something06:44
mithrossk1328: Oh, to make your stuff mergable - we should add documentation in the form of https://github.com/m-labs/migen/blob/master/migen/genlib/sort.py#L506:44
tpbTitle: migen/sort.py at master · m-labs/migen · GitHub (at github.com)06:44
mithroMore info about the documentation at http://hplgit.github.io/teamods/sphinx_api/html/sphinx_api.html06:44
tpbTitle: Simple Formatting Rules (at hplgit.github.io)06:44
ssk1328mithro: Bookmarked both the links!06:45
mithrocr1901: did an excellent job with this file -> https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/gateware/freq_count.py06:45
tpbTitle: HDMI2USB-misoc-firmware/freq_count.py at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com)06:45
mithrossk1328: You should also "rebase" your changes onto of the latest git master06:46
mithrossk1328: I can walk you through the commands to do that type of thing06:46
ssk1328mithro: yeah, the HDMI_Out rework branched I forked very recently06:46
mithrossk1328: Yeah - but lots of changes this week :P06:46
ssk1328mithro: Oh06:47
ssk1328Ok06:47
ssk1328mithro: Okay I am 46 commits behind06:47
mithrossk1328: Compiling the firmware has probably become a bit slower now -- so you might want to wait until you get things working06:48
mithrossk1328: I've made a bunch of the timing constraints a bit tighter06:49
ssk1328mithro: Okay06:49
ssk1328mithro: I should wait then06:49
mithrobrb06:50
ssk1328mithro: What time your local time are we having the meeting?06:50
