Hello,
I would please like to ask about hyperFlash example (evkmimxrt1050_flexspi_hyper_flash_polling_transfer):
In the example, I see the following parts:
1. hyperFlash initialization
2. hyperFlash write of page
3. hyperFlash read of page
4. compare the read and write contents.
I had assumed that flexSPI interface only needs to be initialized (There is LUT for read and write command) , and then can be accessed by direct read/write from the absolute address (where the device is mapped to).
Yet, I see that the write functionality is done through wrappers:
flexspi_nor_flash_page_program -> FLEXSPI_TransferBlocking -> FLEXSPI_WriteBlocking
The read is done by direct access to address, is expected.
Can someone explain why the write must use this wrappers ?
Thank you,
ranran
