I have a booloader application that loads in new firmware in a different part of the flash. After updated I reset the processor and the newly uploaded application doesnt start. I think I must not be updating the vector table correctly because if I simply use the same vector table as the bootloader it works (the small uploaded test application doesnt use interupts). Here is my code in the bootloader.
#define APPLICATION_ADDRESS (uint32_t)0x08002030
typedef void (*pFunction)(void);
// Get the application stack pointer (First entry in the application vector table)
JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4);
// Get the application entry point (Second entry in the application vector table)
JumpToApplication = (pFunction) JumpAddress;
// Reconfigure vector table offset register to match the application location
SCB->VTOR = APPLICATION_ADDRESS;
// Set the application stack pointer
__set_MSP(*(__IO uint32_t*) APPLICATION_ADDRESS);
// Start the application
If I comment out the "SCB->VTOR = APPLICATION_ADDRESS;" line, it works as expected by using the bootloader vector table.
Can anyone please let me know what I am doing wrong?
