Fail to run an AES encryption and decryption program on the MicroBlzae

[d4223738]

Hi,

I am new to the MicroBlaze and SDK. I just managed to get a simple "Hello World" application running on the MicroBlaze on the Nexys 4 DDR FPGA board.

Currently, I am trying to run a larger program - AES encryption and decryption. However, without any errors, the result is always incorrect.

Since the unencrypted data and key are in the program source code, so I debug the code in real time and found out there are mismatches between the value in the source code and the real value in the memory.

Can anyone give me some directions to look into this problem?

Best wishes,

Lei

The problem was that I used the "print" function is the SDK. It was solved by using the "xil_printf" function.
