Hi Biser(All):
Now I debug the x-load in SRAM , because it works well. After my ddr configure is completed , I write some code ddr(MY SDRAM) to read /write my ddr at address 0x8000000.For example ,write 0x8000000=0xA5A5A5A5.And then I read the same address after writing . It's 0x80000000=0xA5A5ABD5. The same ddr address ,but the data is not the same data I have writed.I am confused.I think my ddr configuratiion is not corrected configured.Is there some correct configuration AVGs to my SDRAM?
