The NONMAIN is a dedicated region of flash memory which stores the configuration data used by the BCR(boot configuration routine) and BSL to boot the device. The password used in this example project can also be used for BSL, if you want to change the password, you need to modify NONMAIN flash configuration.
The GUI tool supports not only BSL password modification, but also all the NONMAIN flash configuration options.
