 When it is run, this bootloader looks in the SPI flash memory if a new firmware is available. It there is one, it *swaps* the current firmware with the new one (the new one is copied in the main flash memory, and the current one is copied in the SPI flash memory) and run the new one. If the new one fails to run properly, the bootloader is able to revert to the old one and mark the new one as not working.

 # About MCUBoot
 MCUBoot is run at boot time. In normal operation, it just jumps to the reset handler of the application firmware to run it. Once the application firmware is running, MCUBoot does not run at all.
