xfxfmithro: i see a ram chip, a spartan, what's the NXD (?) chip?08:35
mithroNXD do graphics interfaces08:35
xfxfoh right08:35
xfxfwould that device roughly work the same as the hdmi2usb?08:35
xfxfwell, minus the encoder functionality08:35
mithroxfxf: I'm guessing in a very similar way08:37

sab_123hi mithro09:23
sab_123So I am looking into the FX3 interface also current for USB 3.009:23
sab_123currently for doing USB 3.009:24
sab_123instead of implementing the complex stuff , why dont we use something like the FX3?09:24
mithroThe FX3 is not a part we are interested in using, it's very expensive, requires complicated firmware and doesn't actually enable full super speed transfers09:26
sab_123ah okay09:29
sab_123I agree with you on that I guess09:29
sab_123USB 2.0 on FX2 is supposed to be 480Mbps09:29
sab_123Even on my current project i find it hard to get 12MBps09:30
sab_123In fact I use only the Y in the YUV to display09:30
mithroWe can get round 35Megabytes/s09:39

CarlFKmithro: good morning23:24
mithroCarlFK: BTW the firmware is open source, you can go and look at the code23:24
mithroCarlFK: probably worth getting pdp7 to share that23:26
CarlFKmithro: not a bad idea23:27
CarlFKI did look at the code, that's how I figured out the reboot command23:27
CarlFKthe help and error message is pretty bad23:27
mithroPatches welcome, that is C code that I *know* you can edit23:29
jeamithro: nice post23:32
