gcc - C code to relocate the vector table - Stack Overflow

WebIn our case we wanted to keep the vector table pointing to the softdevice so we locally removed the line of code which sets up the VTOR in the bootloader. If this is the same problem you are having and you don't want to use the softdevice you should be able fix this problem by setting the VTOR to point to the ram copy in nrf_reloc_vector_table(). WebJun 22, 2024 · @Piranha (Customer) I have not tried the call to __DSB(), but I do not have the SCB->VTOR register on the STM32F0 (Cortex-M0 based). And, I am no longer setting the main stack pointer (MSP). From your example, this seems to be a wait for completion of setting the SCB->VTOR and MSP; but, it shouldn't apply in my situation anymore.
