High Performance Low Cost Embedded Systems
Address Space
The left drawing is the memory allocation diagram when the system is set to the Nor Flash boot
mode with nGCS0 being set.
The right drawing is the memory allocation diagram when the system is set to the Nand Flash
boot mode.
Note: SFR Area is reserved for special registers
nGCS0 will map its address space to different devices when the system boots in different modes
- When the system boots from the Nand Flash, its 4K Bytes BootSram will be mapped to
nGCS0’s address space;
- When the system boots from the Nor Flash (not the Nand Flash boot mode), the Nor Flash
which is connected to nGCS0 will be mapped to nGCS0’s address space.
SDRAM address space: 0x30000000 ~ 0x34000000
