CarlFKI am seing something weird:
CarlFKthat is from [email protected]:~/atlys$ while true; do date; xrandr | grep HDMI1; sleep 1; done06:50

cancimithro: I was using the prebuilt bitstream linked directly from the firmware load instructions, same for the fx hex file.21:32
*** hyades has joined #timvideos21:33
cancimithro: Using the buttons to switch the hdmi output between test pattern (repeating boxes of red/green gradient) and one connected input works fine.21:34
*** rohitksingh has quit IRC21:34
cancimithro: From reading the documentation I found, I am not sure what exactly the EDID Hack is supposed to be doing. I pressed the center button with a 1080p monitor connected to the active output (output 0)21:35
canciMy expectation was that a device connected to one of the inputs of the atlys would now see 1080p as supported mode via EDID, however it stayed at 1024x76821:36
canciSince that's the native resolution of our projector anyway, I did not spend to much effort on finding out how it's supposed to work, yet.21:37
canciTo me it seems the prebuilt bitstream is working fine concerning so far, I have already built my own bitstream from the git, however I haven't checked yet, whether that bitstream works21:38
canciOn the USB front I didn't have much success, with the provided hex image, I only get enumeration errors when plugging the usb connection to the atlys board back into my PC21:39

mithrocanci: the board only supports 720p/1024x76822:40
mithrocanci: the edid hack makes it so that the output resolution is just the single value so the computer doesn't have a choice and choose the wrong one (common at conferences)22:42
*** droy has quit IRC22:47
CarlFKmithro: my laptop hdmi to atlys board is still bouncing  I have about 18 hours of log file now22:54
mithroCarlFK: this is before you have loaded the .hex file?22:55
mithroCarlFK: how are you getting this log file?22:56
CarlFKthat is from [email protected]:~/atlys$ while true; do date; xrandr | grep HDMI1; sleep 1; done22:56
CarlFKdjtgcfg prog --verbose -d Atlys -i 0 -f hdmi2usb.bit - have not loaded the .hex22:59
mithrodoing xrandr forces a refresh of the edid structure which will probably cause your screen to flash23:05
CarlFKyeah - it flickers a little23:06
CarlFKit is running on a test machine (pretty much everything I do do isn't on my main box)23:06
