Post subject:	Writing exception handlers
I want to write a handler for 0x4, 0x10, 0xC exceptions on a AT91RM9200 and I code something like this: Code: ... void my_exception_handler() { // do something... } ... void init () { ... AT91F_AIC_SetExceptionVector((unsigned int )0x0C, &my_exception_handler); AT91F_AIC_SetExceptionVector((unsigned int )0x10, &my_exception_handler); AT91F_AIC_SetExceptionVector((unsigned int *)0x4, &my_exception_handler); ... } it compiles/link fine but if an exception is thrown I can see within the debugger that it jumps to 0x10 but from that point my own handler will be not executed. What did I wrong?
