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?
