Code not working after relocate my vector table.

[Param sivan]

Hi,

STM32f429ii. FreeRtos.

I have relocated my vector table from default address into 0x8008000 since my bootloader firmware is placed on in the default start address (0x8000000). I am using IAR workbench, i have modified the vector table address as 0x8008000 and ROM start address as 0x08008000 in the linker setting. I can view the the vector table address is relocated on the 0x08008000 address on the disassembly window. But once I start the debugger, it will stuck on out of the code memory. What will be the issue? Thank you.

It's not enough to just relocate the vectors. You have to point VTOR to it.

Or, the IAR debugger cannot guess where you vectors are and needs some startup command.

Thank you so much.

Yes, once I defined the VTOR it is working fine.

#ifdef __ICCARM__

 #define __Vectors  __vector_table

#else

 extern unsigned char __Vectors;

#endif
