I have been running the NO-OS S/W with the FMCOMMS1.
Here is what I get on the console display
Initializing XCOMM I2C ...
XCOM Init I2C OK!
Getting XCOM Revision ....
Getting XCOM revision Failed
Initializing XCOM Components
XCOM Init OK!
And everything else seems to be OK.
The board works because I can change the frequency of the tone and see it on the spectrum analyzer.
