    It's a memory. You have to write to it first before you can read anything. I guess I don't understand what you are trying to do or what the issue is.

    Thanks, I know this. And finally I found the problem, I used the Avalon MM Master template, but I gave it a reset_n for RESET signal, so it was always in reset state, that results in all ZERO.

    Hi, I still have the problem when using Avalon MM Master template. It is ok to read data from a on-chip memory that connected on Avalon bus when the reading address is less than 0x1000, when above 0x1000 all the data read from on-chip memory is ZERO. The content of the on-chip memory had been initialized to no-zero value.
