I have a DM6437 evaluation board plugged into Window's PC. Modified the PCI sample code to test DDR2 memory. It's extremely slow. Test a page of 8MB DDR2 memory with write and read on every address( 4 bytes aligned ), cost about 3 second. That's put the bandwidth less that 3MB/s (bi-direction), or 6MB/s single direction. It's far below the PCI bus bandwidth, which is 33Mhzx4bytes = 132 MB.
I'm using the CCS3.3 to initialize the board with default gel file, which set the core to 594Mhz and DDR to 162Mhz. Any clue?
Thanks a lot in advance
