in MCF52277RM.pdf section 1.4 Memory Map Overview says IPS is at F000_0000h
yet the .lcf from an example project that came with the 52277EVB has the following:
# MCF52277 Derivative Memory map definitions from linker command files:
# __IPSBAR, __RAMBAR, __RAMBAR_SIZE, __FLASHBAR, __FLASHBAR_SIZE linker
# symbols must be defined in the linker command file.
# Memory Mapped Registers (IPSBAR= 0x40000000)
___IPSBAR = 0x40000000;
4000_0000 is the same address as the external DDR. I'm not experiencing any problems so I think i've just misunderstood something .
Can anyone explain to me why IPSBAR and the external DDR seem to be mapped to the same address space?
