1.27 SFDP Flash Driver - Flash Read Write in Quad IO Mode
This example application shows how to use the SFDP Flash driver to perform block operations on JEDEC-compliant NOR Flash memory in Quad IO mode.
Description
This application uses the SFDP driver to Erase/Write/Read on JEDEC-compliant NOR Flash memory using the QSPI or SQI peripheral library in Quad IO mode.
The application consists of APP_SFDP_Tasks() which is called through SYS_Tasks() routine.
