WebThe " Boot from User Flash " mode means that the application code that will be run after reset is located in user flash memory. The user flash memory in that mode is aliased to start at address 0x00000000 in boot memory space. Upon reset, the top-of-stack value is fetched from address 0x00000000, and code then begins execution at address ...
