 This is the most basic option for external SPI RAM integration. Most likely, you will need another, more advanced option.
 
-During the ESP-IDF startup, external RAM is mapped into the data address space, starting at address {IDF_TARGET_PSRAM_ADDR_START} (byte-accessible). The length of this region is the same as the SPI RAM size (up to the limit of {IDF_TARGET_PSRAM_SIZE}).

 Applications can manually place data in external memory by creating pointers to this region. So if an application uses external memory, it is responsible for all management of the external SPI RAM: coordinating buffer usage, preventing corruption, etc.
