I executed the command you provided at the console with no matches. I noted that the highest memory address tested was ffffff which makes sense considering the system has 16 MB RAM. Here is my physical memory map: 0x0 - 0xfffff : SDRAM 0x8000000 - 0x83FFFFF : Flash 0x9000000 - 0x90FFFFF : FPGA 0xEF600000 - 0xEFFFFFF : PPC405GP memory mapped registers 0xFFE00000 - 0xFFFFFFFF : BootPROM Does this help? Thanks again, HK
