About a year or so ago I bought a Sabre Lite board from Element14.
I am glad to report that after the success with the PI I have now
managed to run DATV-Express on the Sabre Lite too.
I am using the 12.04 distribution from Linaro for the i.MX6.
I had to re-compile the Kernel to get compatible driver modules.
While rebuilding the system I added PVR USB2 support and support
for various satellite receiver dongles. So it should be possible to use it
for receive as well as transmit.
I am able to transmit a solid 4 Msymbols/sec FEC=7/8 DVB-S signal.
With DVB-S2 I can transmit 1 MSymbol/sec FEC= 9/10 APSK16, S2
requires more processing. The source code is the same as the Intel
version, I expect it can be optimised.
With no fans and no noise and a power consumption of < 10 watts
I am even doing my bit to save the planet from global warming.
