I'm not getting one with the current (unfinished) WRU4 baseboard. Which has no SPI. > Just as a thought (not ready): Could we supply CS initialisation > data via defines in the > baseboard config header and append it to the tables if needed? Not sure if I understand this correctly. Could you give an example? Again, my current baseboard has no SPI at all. Thanks, Stefan
