WebFor example, on a STR710 MCU (ARM7TDMI) the vector table is fixed at address 0. Either the on-chip flash or the on-chip RAM can be mapped (and re-mapped at run time) at address 0. I believe the same feature is present in the STM32 family, for example. Having the vector table in RAM gives the necessary flexibility to implement a bootloader. WebI made changes to the vector table location using this function as such: NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x8004000) i.e changed SCB->VTOR = 0x8004000 to this location.
