How to debug the ENSM can't enter RX state

Dear sirs,

My AD9361 configurations are as below:

1. TDD mode

2. Alert = 1

3. txnrx and Enable(level) by pin control.

I try to do TX/RX stress test and monitor the ENSM state[3:0] by LA, the state seems ok(Tx:5->6->7,Rx:5->8->9).

After over night testing, the TX state is still OK, but RX can't enter RX state(8)

Is there any debug port to check why the ENSM can't enter RX state? 

Thanks,

YF
