Daixiwen,

I followed Nios II Architect design Tutorial document. On Page 3-11: Reassign Component Base address to Eliminate Memory Conflicts after "Auto Assign Base Address".

If I clicked Auto-Assign Base Address, it has the following error messages:

Error: ddr_sdram.s1: Appears at more than one address (0x00000000, 0x08000000)

Error: lcd_sgdma.csr: Appears at more than one address (0x02000000, 0x0a000000)

When I changed Base address as the document instructed, One page 3-11 (2.), then I got the previous error messages.

I am a newbie on FPGA. I need a whole picture of memory management on FPGA. But if someone can hint me what might be wrong, it will help me a quick start.

Thank you,

david
