SC600 Devboard. How can we switch microphones

SC600 devboard has two microphones MEMS and ECM type. The ECM microphone is default. How we can use the MEMS microphone?

Dear customer:
sorry, I am not clear what you want to do.
you want to use MEMS mic on you board or you want to use MEMS mic which on our EVB.
As I know, On our EVB MEMS mic connect to mic1, ECM mic connect to mic2.
if you just want to test this two mic, you can use tinyalsa.
if you want to check if you can use two MEMS mic on your product, it answer is yes.
