cr1901_modernmithro: What would cause the following behavior (device number 12 and 13).00:00
cr1901_modernThe Opsis came back as a JTAG device in between showing up as unconfigured00:00
mithrocr1901_modern: that is normal00:02
mithrocr1901_modern: the FX2 boots faster than the FPGA, so it comes up in unconfirmed mode. The gateware boots and it now it is ready, it resets the FX2 which then loads the real firmware from the FPGA.00:03
mithrocr1901_modern: this also means that if the gateware doesn't boot, the FX2 will just appear in unconfigured mode00:04
mithroMakes sense?00:04
cr1901_modernmithro: Okay, that makes sense then.00:04
cr1901_modernI must've actually done the power cycle between 13 and 14 then (I don't remember lol)00:04
cr1901_modernmithro: I had to do a power cycle to get rid of the proxy bitstream when flashing the EEPROM00:05
mithroFlashing the EEPROM?00:06
cr1901_modernmithro: Err sorry00:06
cr1901_modernI meant flashing the SPI Flash00:06
* cr1901_modern has _NOT_ touched the eeprom tonight00:06
mithroOkay. Bblr00:12
tpbTitle: GitHub - jimmo/numato-mimasv2-pic-firmware at xmodem (at
cr1901_modernmithro: Okay, _most_ of my confusion has been alleviated00:30
cr1901_modernmithro: My Opsis came w/ firmware from Jan 2016. The FX2 appears to have defaulted to serial mode back then00:31
cr1901_modernmithro: (Well "serial and webcam" simultaneously)00:31
cr1901_modernmithro: Does this cound accurate?00:32
cr1901_modernmithro: Is it possible to use --flash-image option of hdmi2usb-mode-switch without sudo?01:04
cr1901_modernEver since I flashed the new firmware successfully (and confirmed the new firmware is running) I can't access the FPGA from JTAG pins...01:05
mithrocr1901_modern: install the udev rules02:08
mithrocr1901_modern: that should make it possible to use mode-switch without root02:09
cr1901_modernmithro: I did that, with no effect on --flash-image option02:10
cr1901_modernin any case, I am recompiling openocd right now (b/c they convenient don't enable libftdi usb blaster by default)02:10
mithroHrm, did you did you connect / disconnect after Opsis after installing the udev rules?02:10
cr1901_modernmithro: No02:11
cr1901_modernShould I have?02:11
mithrocr1901_modern: how we build openocd at the moment -
tpbTitle: conda-hdmi2usb-packages/ at master · timvideos/conda-hdmi2usb-packages · GitHub (at
mithrocr1901_modern: a long while back I started trying to get all our tools to build under windows -
tpbTitle: GitHub - timvideos/conda-hdmi2usb-packages at windows (at
tpbTitle: conda-hdmi2usb-packages/.appveyor.yml at windows · timvideos/conda-hdmi2usb-packages · GitHub (at
mithroI don't remember where I got too...02:14
tpbTitle: AppVeyor (at
cr1901_modernmithro: That's good! Unfortunately, long story short, as-is mode-switch isn't going to really work as intended on Windows due to libusb limitations on Windows.02:22
cr1901_modernmithro: I got sudo problem fixed, and openocd actually talked to the board, but mode-switch hung w/ no output after a while02:26
cr1901_modernwould be nice to have an indicator (such as redirecting openocd's stdout to the console) so I could know whether it crashed or not02:27
cr1901_modern Ummm, mithro, what do you mean by "confused"?02:32
tpbTitle: Check for common issues when flashing · Issue #33 · timvideos/HDMI2USB-mode-switch · GitHub (at
cr1901_modernnevermind it works... just takes... a while to load firmware02:38
mithrocr1901_modern: give it --verbose03:08
cr1901_modernmithro: Okay, openocd is in fact working properly. The blaster JTAG port is just slower than my other standalone JTAG programmer03:17
cr1901_modern(can do the write in about 45s vs 140s for blaster)03:18
cr1901_modernBut that's a nitpick at this point. Point-blank, opsis is working. I'll worry about my other concerns tomorrow b/c I feel sleep rearing its head...03:18

mithrorohitksingh: afternoon :-P14:09
rohitksinghmithro: good evening! :)14:17
mithrorohitksingh: Hows your USB project going?14:36
mithroFinally! -
rohitksinghmithro: That holy level of awesomeness! :) :o15:52
rohitksinghmithro: Great achievement!15:52
mithrorohitksingh: Needs a whole bunch of cleanup15:53
rohitksinghmithro: still, its excellent achievement! :0  \o/15:55
rohitksinghmithro: btw all my side projects are on hold for now, atleast until mid-october :( Fully occupied into personal errands16:05
cr1901_modernmithro: Nice work. Someone wants me to add SUMP2 support (when I have time)17:51
