Memory Map
While most NetBurner devices have parallel Flash memory, the Nano54415 has SPI Flash, which means is not part of the processor’s memory map. The two tables below show the processor memory map, followed by the SPI Flash memory map.
Memory Region | Adress Range | Description |
Undefined | 0x00000000 to 0x01FFFFFF | Undefined area to catch null pointers |
SDRAM | 0x40000000 to 0x43FFFFFF | 64MB of SDRAM |
VBR | 0x40000000 to 0x400003FF | 1K Processor Vector Base Register |
RAMBAR | 0x80000000 to 0x8000FFFF | 64K Processor internal SRAM |
IPSBAR | 0xE0000000 to 0xFFFFFFFF | Processor internal device registers. Accessible using the sim structure defined in sim5441x.h . |
Memory Region | Adress Range | Description |
SPI Flash | 0x00000000 to 0x007FFFFF | 8MB SPI Flash memory |
System Config Rec | 0x00000000 to 0x00001FFF | 8K System Configuration Storage |
User Params | 0x00002000 to 0x00003FFF | 8K User Parameter Storage |
