For STM32446E-EVAL demonstration, the memory heap is located in the external SDRAM
memory.
Note:
For STM32F479I-EVAL, STM32F469I-DISCO and STM32F412G-DISCO demonstrations
the memory manager is not applicable.
shows the different APIs offered by the memory manager module.
For STM32446E-EVAL demonstration, the different icons of the applications are stored in
the external memory QSPI, configured in memory-mapped mode to the STM32 address
space, and seen by the system as if it were an internal memory.
This mode provides a direct interface to access data from external SPI memory and thus
simplify Software requirements.
