1.22 Memory Driver Synchronous - NVM SST26 Read Write

This example application shows how to use the Memory driver in synchronous mode to perform block operations on the NVM and the SST26 media’s.

Description

  • Uses multi instances of the Memory driver to communicate with the NVM and the SST26 Flash memories in synchronous mode of operation in RTOS Environment.
  • Performs block Erase/Write/Read operations on both the media’s
  • Consists of three tasks which are called in the RTOS thread context:
    1. APP_SST26_Tasks():
      • Performs operations on the SST26 QSPI/SQI Flash Memory
    2. APP_NVM_Tasks():
      • Performs operations on the NVM
    3. APP_MONITOR_Tasks():
      • Monitors the state of above two Tasks
