Surely the syntax is

#ifdef VECT_TAB_RAM

/* Set the Vector Table base location at 0x20000100 */

NVIC_SetVectorTable(NVIC_VectTab_RAM, 0x100);

#else /* VECT_TAB_FLASH */

/* Set the Vector Table base location at 0x08008900 */

NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x8900);

#endif

More likely the table is not built correctly. Have you checked the errata?

Hi Clive1,

thanks for your reply. You´re right, but because the offset will be ''OR´ed'' with 0x08000000 respectively 0x20000000 inside the NVIC_SetVectorTable function, it is not wrong to write the offset with the complete address.

The errata sheet say´s nothing to this problem.

Greetings
