CarlFK[m]Flash the same firmware version, maybe there's something different going on, I'm just randomly guessing now00:38
shenkiCarlFK: okay. where do I grab the latest fx2 firmware?00:41
*** TheAssassin has joined #timvideos00:42
CarlFKshenki: the latest doesn't work.00:58
CarlFKoh, fx2 - that is all one blob00:59
CarlFKor it doesn't apply to Opsis00:59
shenkiI don't know - that's why I'm asking :)01:01
shenkiah, it loads the actual firmware over i2c. I guess that would make the i2c jumpers important01:03
shenkiCarlFK: do you know how the jumpers should be installed?01:04

shenkiCarlFK: hrm. why doesn't mplayer see data?01:45
CarlFKshenki: I've learned to ignore such questions :p01:45
shenkiCarlFK: ok. what do you use to preview the video?01:46

CarlFKgst (gstreamer) is what feeds voctomix, so as long as that works, we can record talks.01:46

tpbTitle: Any recs for a PCIe FPGA board for High Speed logging (Linux Kernel development) : FPGA (at
rohitksingh_workfutarisIRCcloud: thanks! I've shared it with Numato guys. The PCIe Gen2 issue has been already resolved afaik by simply upgrading to higher-speed grade of same FPGA. Plus they are going to try out Artix 200T on Aller in few days from now. The FPGA footprint is same, plus 200T will have better thermal disspation due to low thermal impedance between heat-sink and the silicon die.06:25
rohitksingh_workRAM capacity will be addressed in a future revision of Aller in ~2 months06:25
