Relocating vector table cortex M3 question.
Hi,
im using CC2538(cortex m3)
if i want to port on CC2538, i have to relocate vector table.
so i had searched datasheet, i founded my code have to be located at 0x0020_0000~
but, vector table address is set at reset 0x0000_0000. this is rom area.
so i have to relocate vector table address.
i had tried access vector table offset register(VTABLE) <- other vendor’s register name was VTOR.
i just had access this register and just allocate appropriate value.

Are you sure you have to relocate the table? Lots of Cortex-M will mirror the vector table region in memory to address 0 even when there is no physical memory at 0.

yes ! i had checked datasheet and i had tested it.
if i didn’t relocate vector table’s addres, it didn’t work.
but attached below code
