AD9361 TX LO calibration lock failed

Hi guys,

I have ported the latest linux driver about AD9361 to my kernel, and I found that TX LO is lock failed sometimes.

 

1. When LO is lock failed, I print the value of register 0x287, it's 0x42. But the driver didn't puts warning : "Calibration TIMEOUT  (....)"

2. When the LO lock failed (0x287=0x42) at once , I can't let LO lock again even though I change other frequency through "out_altvoltage1_TX_LO_frequency" . And the value of 0x287 is still 0x42.

 

Could you please tell me how to fix this problem?

 

Thanks a lot.
