[liyang]

with freertos based on SDK13, fds init pass, but fds write fail, no trigger the FDS_EVT_WRITE, why? 

I don't fds write in the interrupt content.

If I understand correctly, you receive the event FDS_EVT_INIT?

The example in this answer shows how to implement and test FDS. Could you compare it with your implementation?
