Overview
|
|
========
|
|
The flexspi_nor_polling_transfer example shows how to use flexspi driver with polling:
|
|
|
|
In this example, flexspi will send data and operate the external Nor flash connected with FLEXSPI. Some simple flash command will
|
|
be executed, such as Write Enable, Erase sector, Program page.
|
|
Example will first erase the sector and program a page into the flash, at last check if the data in flash is correct.
