Part Number: TMDXRM57LHDK
Other Parts Discussed in Thread: RM57L843

Tool/software: Code Composer Studio


I am working on SDRAM on TMDXRM57LHDK kit. I want to write the different location of SDRAM and then read back this locations. Code is attached blew.

My program is reading and writing this locations but problem is, SDRAM on this kit is 64Mbit and in memory map of RM57L843 address allotted to SDRAM is from 0x80000000 to 0x87FFFFFF (128MB). So according to my understanding do to smaller SDRAM, program should write and read only 0x80000000 to 0x80800000 address range. All other locations (0x80800001 to 0x87FFFFFF) should not be write and read. But program still write and read this locations (0x80800001 to 0x87FFFFFF) . I have checked the values in memory browser. So if this program is writing the locations (0x80800001 to 0x87FFFFFF) then what are the physical location of this write and read?
