Hello ,


I have problems using the External LO option in IIO-oscilloscope.(both in FDD mode and TDD mode).


My Hardware is : AD9361 on the AD-FMCOMMS3-EBZ mounted on ZC-706REV 1.2 board.


I tried in few scenarios:


In TDD mode:

When I'm trying to move from alert to tx mode the debug massage is " ad9361 spi32766.0: Invalid ENSM state transition in TDD mode".

When I'm trying to move from alert to rx mode the debug massage is "ad9361 spi32766.0: failed to find suitable LPF TIA value in gain table".

in both cases the ENSM go back to alert mode.


In FDD mode:

after I setup the external LO option the ENSM moved to alert and I didn't manage to return to FDD mode.

I tried few time and the same results I got.


Updating ADI tools didn't help to solve this situation.


The external LO option is working or I need to do something else in order to use the external LO?
