I guess that is the recipe for the vector table stored in RAM (SYSRIVECT bit of SYSCTL set). I already did this and it works ok, although I let the application to register its interrupt handlers itself, the SYSRIVECT is set by the bootloader. But still I need to know if it's doable to make the bootloader use just reset vector and the application to define all interrupts except reset. It's like to create the application that has no init, I'm ok with it because I know the bootloader has and expect the bootloader to be called every time the MCU powers up. Of course I can program only by bootloader (and then intentionally skip 0xFFFE address) but I wanted a handy and convenient solution that could be flashed with mspdebug.
