Hi, Team,

We are trying to make "2Loop TCXO APLL" DCO mode configuration, but there is a run script error.

Hello Yone-san,

I have confirmed the error is associated with the selection of DPLL# Mode = 2 loop: TCXO, APLL. Other modes work fine.

I will continue to investigate find the root cause and the solution or bug-fix.
