Hi Josh, we don't manage wih the E100 FPGA5 bitstream. It is placed in the images directory and we use a new branch but we don't really think the FPGA5 is used. And we still have the same problem with parallel UHD devices (sink/source). Which branch shall we use? Can you pinpoint exactly? Shall we use the Josh branch from http://gnuradio.org/cgit ? Do you have images available? We still don't have a cross-compile env. yet. Hence compilation takes very long time... Another topic we recognized on E100 is that we suspect incomplete datastreams when the Gumstix is overloaded performancewise. I will come back with details on our transmitter setup which might cause overloads. But - is it possible to overload the 720MHz Gumstix easily? What happens in this case - samples are discarded?
