[NUC472] EBI SRAM Heap

• Application: Heap Space on EBI SRAM
• BSP Version: NUC472/NUC442 Series BSP CMSIS v3.03.000
• Hardware: Nuvoton NUC472 Demo Board V1.0
  

NuMicro® NUC472/NUC442 series is equipped with an external bus interface (EBI) for connecting external devices. NUC472/NUC442 EBI facilitates connecting the device of which control interface is composed of address, data, chip select, and read/write strobe, for example NOR flash, NAND flash, and SRAM. In example EBI_SRAM_HEAP, NUC472/NUC442 employs EBI to connect a SRAM device and make this SRAM as extended memory. The Keil project configures the heap space of EBI_SRAM_HEAP to locate on address of EBI SRAM. This example uses malloc() to allocate memory from heap, that is, EBI SRAM.
