CarlFKoy boy - this is new: DNA = 101111111111111111111111111111111111111111111111111111111 (0x17fffffffffffff00:00
tawmfutarisIRCcloud: this article makes me hopeful: http://billauer.co.il/blog/2015/12/usb-superspeed-parallel/00:01
tpbTitle: USB 3.0 is a replacement, and not an extension of USB 2.0 (at billauer.co.il)00:01
tawmbut then again, if both buses running in parallel is a temporary thing, relying on having both might be a bad design decision (apart from probably being way out of spec...)00:02

CarlFKtawm: do you know what the hdmi2usb is?02:28
CarlFKor.. I have 2 usb uvc videos devices.  they should be identical.  (they arent)  I have a pretty high level test (gstreamer command) that shows they are different02:30
CarlFKI'm wondering how I can sniff the usb traffic so I can diff02:31

tpbTitle: FireAnt | Crowd Supply (at www.crowdsupply.com)03:21
CarlFKI got excited by https://github.com/xips-tech/FireAnt but thats just instructions on how to download the software03:41
tpbTitle: GitHub - xips-tech/FireAnt: "Very low cost, tiny (USB thumb size) FPGA board. 1st board with Efinix Trion FPGA and comes with Efinity IDE Solder or unsoldered version - ready to go with a PC and no extra components. Breadboard friendly to allow quick application with sensors, peripherals or other interfaces For hobbyist, students learning digital design or manufacturers prototyping with new Efinix platform" (at github.com)03:41
CarlFKmithro: we have a problem: https://veyepar.nextdayvideo.com/static/temp/opsis-v0.0.4-489-geaab51f.png  (broken uvc video)03:57
futarisIRCcloudCarlFK: https://youtu.be/0mTw9iHcj3Q?t=16309 that's a recent talk on sniffing USB. You can use usbmon on a linux kernel without external hardware...04:33
CarlFKfutarisIRCcloud: maybe next time - I've found out enough04:39
CarlFKIll try to remember to search the logs if I need it again04:39

CarlFKmithro: what does this mean?19:12
CarlFKmithro: (LX P=arty C=or1k) [email protected]:~/tv/litex-buildenv$ export CPU=or1k PLATFORM=opsis TARGET=hdmi2usb19:12
CarlFKmithro: Makefile:28: *** "FULL_PLATFORM was set to 'arty' (arty), but PLATFORM was set to 'opsis'.".  Stop.19:12
CarlFKmithro:  or really, what should I do about it?19:12
mithrounset FULL_PLATFORM19:32
CarlFKmithro: k19:44
CarlFKmithro:  is this because I need the other xilinx tool?  OSError: no version directory for Xilinx tools found in /opt/Xilinx/19:44
CarlFKmithro: I got that from (LX P=opsis T=hdmi2usb C=or1k) [email protected]:~/tv/litex-buildenv$ make gateware19:44
CarlFKyeah, this:  for these FPGAs you will need to use Xilinx ISE instead.19:47
mithroYes19:51
CarlFKmithro: do I want ISC webpack or design suite?20:26
CarlFKmithro: I guess webpack given that's the licence I should have20:27
mithroYes, webpack20:27
CarlFKmithro: after make gateware, what file do I  flash?20:39
CarlFKgrumble - ERROR:Map:258 - A problem was encountered attempting to get the license for this    architecture.20:42
