STK1002/Memory mapping

From AVRFreaks Wiki

Jump to: navigation, search

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 selectMemory devicePhysical address
EBI - NCS08MB External Flash0x0000_0000 - 0x03FF_FFFF
EBI - NCS18MB SDRAM0x1000_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.
