I want to know how to get the result of the OSPI Controller polling the status register?
As the TRM mentions, this can be achieved by sending the RDSR opcode to the FLASH device and waiting until the device itself has indicated the write cycle has completed (until the Write in Progress bit has cleared to zero and the write enable latch bit has also cleared to zero or device is ready bit has set to one).
The address of the Write in Progress (WIP) register is a part of the flash data sheet.
