User program conditions
AN2078
On STR7xx MCUs, the IAP driver should be programmed at the Flash base address
(sector0 base address) and the user application should be programmed from bank0 sector1
base address. If the application to be programmed to the STR7xx internal Flash uses
interrupts, it should provide software remapping of RAM to address 0x0 and also the
exception vectors should be copied to this same address as illustrated in Figure 4.
