What does the kernel message "ad9361 spi32766.0:ad9361_dig_tune: failed!" mean?

Hi All,

 

On my "ZedBoard+AD9361 RF Hardware evaluation Board" platform, Kernel print start message "ad9361 spi32766.0:ad9361_dig_tune: failed!" twice. Does it mean that initialization of AD9361 can't be finished ? What could be the cause of this problem? If I run the program of "osc"(iio-osciloscope) in this case, what will happen?? crash ?

 

Thanks a lot!

 

Best Regards,

Lee
