We are using i.MX 8M Plus LPDDR4 EVK. I believe it is MIMX8ML8DVNLZAA. We download SDK version 2.12 and then at a latter date download SDK version 2.14. Method ECSPI_InterruptGetStatus() is the same in both versions.

Hello @frank9 ,

Thank you.

Is there a way to replicate your issue?

I really do not have any more information to share beyond what I posted. In my application, I decided to check driver busy status by calling ECSPI_InterruptGetStatus() before starting a SPI transfer, and that was when I encountered this issue. With the posted modification to ECSPI_InterruptGetStatus() my application appears to be functioning correctly. I just wanted to share a modification that I needed to implement.
