Hello,
I have written my own sdram-controller which addresses a sdram with the memory-range from 0x04000000 - 0x04ffffff. I have an original sdram-controller generated by the NIOS II software which addresses a sdram with the memory-range from 0x02000000 - 0x02ffffff. Both controllers are connected to the NIOS II processor programmed in the FPGA. When I run my program in the memory-range from 0x02000000 - 0x02ffffff everything works file. Simple testing then the sdram with the memory range from 0x04000000 - 0x04ffffff gives no errors. When I try to run my program in the memory-range from 0x04000000 - 0x04ffffff I got a verifying error when loading it into the sdram. Is there a way to check what has been loaded into the sdram from memory-locations 0x04000000 - 0x04ffffff. I tried to use nios2-download but there are no options to read data from sdram-locations. I think it can only download data to sdram. Does somebody have some idea how I could check the contents of the sdram. Regards, WMOLink Copied
