Hi Christian,
thanks for all your work and the major update.

For this to get working, we had to rewrite major parts
of the ARM
firmware and the FPGA VHDL code. Today this work is completed and I
can report success: The OsmoSDR now delivers up to 4msps at 14bits.
Also the strange peaks around Niquist/zero frequency are gone.
great!
We will now integrate the changes into the OsmoSDR
mainboard and
reroute the now free SSC pins to the pin headers instead of the MCI
interface. Also we will add the opamps.
Are you going to do more or less full re-route of the board? If yes, it
might be worth designing the size such that it can fit into a
standard-size (shielded metal) case. This doesn't mean that everyone
would have to operate it in such a case, but at least it would be nice
if an off-the-shelf case could be used.
For the already produced OsmoSDR boards, we will have
more of the
prototype stack-on-top-boards.
do those boards only address the opamp / matching, or actually the
SD/MMC interface between FPGA and SAM3U?
Regards,
Harald
