I am using STM32F427 microcontroller,I have couple of binaries(lets consider bootloader and Application) converted to hex and combined in intel format. I am flashing intel format hex image to flash. I wanted to jump from bootloader to Application. My start address of bootloader and Application are 0x08000000 and 0x081C0000 respectively. Now I wanted to know procedure to jump. I tried modifying the start_xxx.s
LDR R0, =SystemInit BLX R0 LDR R0, =__main BX R0 ENDP
replaced main with 0x081C0000, but failed. Secondly tried updating the VECT_TAB_OFFSET in system.c to 0x001C0000
SCB->VTOR = FLASH_BASE | VECT_TAB_OFFSET; but this too failed.
Like to know anyother methods to jump it in flash itself and any examples to copy flash to RAM
