Hi all,
OBS1: i'm not a specialist in C.
running the ADC example we have this code in configuration function. I dont know if this lib package is distributed by keil or ST. I received it from ST people with some keil examples.
#else /* VECT_TAB_FLASH */ /* Set the Vector Table base location at 0x08000000*/ NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0); #endif
the NVIC_SetVectorTable function is:
void NVIC_SetVectorTable(u32 NVIC_VectTab, u32 Offset) { /* Check the parameters */ assert(IS_NVIC_VECTTAB(NVIC_VectTab)); assert(IS_NVIC_OFFSET(Offset)); SCB->ExceptionTableOffset = NVIC_VectTab | (Offset & (u32)0x1FFFFF80); }
so, compiling this code with keil it is a 4798 bytes long. But if i hide the function call and write all the code inside the function...
#else /* VECT_TAB_FLASH */ /* Set the Vector Table base location at 0x08000000 */ //NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0); assert(IS_NVIC_VECTTAB(NVIC_VectTab_FLASH)); assert(IS_NVIC_OFFSET(0x0)); SCB->ExceptionTableOffset = NVIC_VectTab_FLASH | (0x0 & (u32)0x1FFFFF80); #endif
... the code is 3682 bytes long. I think that 1k for this function is so much. Can anyone explain what is happening? (forget about the assert function because i disabled #DEBUG)
thanks!
Also, you want to compare the .map files to see where the extra code is coming from, not the .lst.
