Excessive sector erase times (evkmimxrt1064_flexspi_nor_polling_transfer)

Hello,

 

Running the example program indicated in the title, it needs about 17 seconds to erase a single flash sector! The flash data sheet indicated that it needs about 300ms (internally) to erase a single sector. I'm using a MIMXRT1064-EVK evaluation board.

Can anybody please try this too, and tell me what the results are? What could be the root cause?

 

Thanks in advance.
