      Hi @JingyangTeh_Altera

      Also, I tried to run the project (with the vector) in steps to see where is the problem, I got the following error in the command view and Disassembly view, apparently, the system couldn't access the two addresses 0x80000068 and 0x8000006C. For your information and support please.

      ------------------- Error in the Disassembly view --------------------------
