Is it possible to relocate the interrupt vector table? (niwnfyc)
I'm using the dsPIC33FJ256GP710 with the C30 compiler.
Is it possible to move the IVT to a different memory address? What I would like to do is setup a bootloader that uses memory locations 0x00000 to 0x04FFF, and then the main program uses ONLY addr..

Do we really need the volatile qualifier? (DavidePizzolato)
In the forum, a common answer to solve problems with interrupts is something like “declare the variable as volatile”. I have fully functional softwares with many shared variables and many interrupts, without any volatile variable. I wonder if sooner or la..
