Hi, I have success fully build and run a project in the pc386 BSp and UNIX BSP. Later when I build the same project for the psim BSP.The program ran in the psim but did not return SUCCESS.(that is the ..it did not produce the same same out put as in pc386 BSP and UNIX BSP) What could be possibly wrong? The only system call that is used by my code is malloc. Thanks, Kiran
