STK1002/Memory mapping
From AVRFreaks Wiki
The physical address space of the memory on STK1000 depend on the chip select connected to the memory devices. The following section describe how this is done for STK1002.
Memory mapping
The external memory on STK1000 is selected by the following chip select signals and thus leading to the following mapping to physical addresses.
Chip select | Memory device | Physical address |
---|---|---|
EBI - NCS0 | 8MB External Flash | 0x0000_0000 - 0x03FF_FFFF |
EBI - NCS1 | 8MB SDRAM | 0x1000_0000 - 0x1FFF_FFFF |
Notes to the developer
Please note that memory is wrapped such that the 8MB memory selected by NCS0 will be repeated 8 times in the 64 MB memory area to which it is mapped.
