AN1388APPENDIX D:BOOTLOADERCONFIGURATIONSThe bootloader code provides a few macros forconfiguring the settings while compiling. Table 5through Table 8 list these macros and their usage.Depending on user requirements, the values in thesemacros may need to be changed.TABLE 5: GENERAL MACROSMacroAPP_FLASH_BASE_ADDRESSAPP_FLASH_END_ADDRESSUSER_APP_RESET_ADDRESSMAJOR_VERSIONMINOR_VERSIONUsageBase address of the program Flash reserved for the user application. Theaddress value must point to the beginning of a 4K Flash page.End address of the program Flash reserved for the user application.
