ISR & interrupt Vectable

hello everyone,

   I want to load an ISR into the address of the interrupt vector table, but when I debug, I will enter a bus fault. I don't know how to solve it.

Hi @jayzhou,

I understand the vector table is in SRAM, and you want to install an ISR to the table.

If you use RTD, there is already an API for that, you can refer to the code.

Is the vector table in SRAM?

What is the value of the VTOR register?
