使用ipCore从RAM读取并写入寄存器的问题

嗨，
我正在使用EDK 8.2和一个简短的3开发板。
我在上面运行了MicroBlaze 5。
我的ipCore连接到OPB，具有8K RAM（4x RAMB16_S9_S9）并分配了两个寄存器。
第二个BRAM端口连接到OPB BRAM控制器。
也分配了地址空间和大小。
我正在用Xio_In和Xio_out编写和阅读。
我想通过OPB将MBlaze中的c代码写入我的ipCore中实现的RAM（已尝试直接实现BRAM，并且还将端口添加到我的ipCore以将其连接到来自EDK的bram_block）
将来自RAM的数据放入ipCore的寄存器中，然后从MBlaze中读回来证明写入的成功。
模拟结果很好。
（模拟ipCore，BRAM和OPB BRAM控制器在一起）
但是将代码放在斯巴达设备上我不会从给定地址读取数据。
不知何故，地址被转移，但我没有看到这种转变的重要方案而不是错误的原因。
如果你能帮助我会很棒。

Hi,

I'm using EDK 8.2 and a spartan 3 developer board.
I got a MicroBlaze 5 running on it.
My ipCore is connected to the OPB, has 8K RAM (4x RAMB16_S9_S9) and has two registers assigned.
Second BRAM Port is connected to an OPB BRAM Controller.
Adressspace and sizes are assigned, too.

I'm writing and reading with Xio_In and Xio_out.

I want to write data from the c-code in the MBlaze via OPB to the RAM implemented within my ipCore (already tried direct implementing BRAMs and  also adding ports to my ipCore to connect it to a bram_block from the EDK)
put the data from the RAM into the registers from the ipCore and read it back from the MBlaze to proof succes of writing.

Simulationresults are fine. (simulated ipCore, BRAMs and OPB BRAM Controller together)

But putting the code on the spartan device I don't read the datas from the given address.
Somehow the adress is shifted but I don't see a significant scheme in the kind of shift not the reason for the error.

Would be great if you could help me.
