Summary: Can't test AWG through sport-spi add on card in 2011r1 and trunk

Details:

 

Because spi_adc related structures were removed from stamp.c of bf537, so we can't test NDSO and AWG through sport-spi add on card in 2011r1 branch and trunk.

 

Follow-ups

NDSO and AWG tests were already been converted to use bfin_sport.c driver other

than the obsolete bfin_spi_adc.c driver. Please select correct driver and run

again.

NDSO can work now.

AWG still fails to catch generated waveform.

 

--- Sonic Zhang                                              2011-12-12 05:20:43

The Vref pin of ad5443 over sport is 0 volt. Should connect the SPORT PIN1 to

SPI PIN1 on the SPORT-SPI conversion board.

Fixed in hardware.

OK now and close it.
