Hi All, We have a DM640-based custom board with CPU operating at 400MHz. This board was working fine. Now we have replaced the DM640 with DM642-720 chip. The input PLL clock is same, i.e. input PLL clock is 33MHz and DM642 CPU is also running at 400MHz. Is this fine? We are trying to access SDRAM using the same GEL file as used for DM640 board. Since we have not changed any cloc...
