When hook routines are enabled, after one hook function call, the execution went to invalid address locations. When the it is disabled, the program works fine. When I changed to SVC mode, then also it was working fine. When analyzing, the stack used was the previous task's stack pointer.
So, when checking a function call, not only check whether the registers are properly saved and returned. But, also check the stack used is not corrupting others. Even when checking a function, check once with changing the stack pointer.
