Hi guys,

 

     We are developing customized AD-FMCOMMS3-EBZ board.

     We are encountering with problem in digital tuning the both Tx Channel and Rx channel during booting up of the linux in CMOS mode.

     We are getting the following messages during Linux kernel boot up.

 

     SAMPL CLK: 61440000 tuning: RX

       0:1:2:3:4:5:6:7:8:9:a:b:c:d:e:f:

     ad9361 spi32766.0: ad9361_dig_tune: Tuning RX FAILED!

 

     SAMPL CLK: 61440000 tuning: TX

     ad9361 spi32766.0: ad9361_dig_tune: Tuning TX FAILED!

     cf_axi_adc: probe of 79020000.cf-ad9361-lpc failed with error -5

 

     Basically, we are not able to see any data transfers to and from the customized board after the customized board is booted up.

 

     Can anybody guide us as to how we can resolve the issues in digital tuning both Tx and Rx channels?

     Can anybody summarize the steps to be followed to trouble-shoot the issues related to digital tuning of the channels?

 

     Thanks in advance.
