Sorry, I forgot to the most important definition
in the specification : 7. I need to update the application
section (RWW) + (NRWW) excluding the boot loader section (this probably means that the interrupt
vector table in the boot section must be replicated in the high end part of the
application (NRWW section). Due to the fact that I can not ch’ange
the vector jump table in the boot section I propably have to have an added
interrupt ventor jump teable In the application NRWW section at a
fixed start address, hose jumps change depending on the new addresses of the
ISRs in the application section. Please, see the diagram below : Da: Carlo Ossanna
