ASA,
The problem occured due to the use of wrong source files to generate the FPGA
image. I discovered the problem by using the pre built images
at http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD_build. The 'S'
problem occured when I used the prebuilt image at 003.004.000. So, I used the
version 003.004.001 and everything is just great.

S. Yassin

With tx_waveforms on B100, it starts to print 'U' at 6Msps.
But CPU consumption is only in 20% to 25% range.
Its fine at 5Msps and lower.
