IBAH (25.05.2023 10:17, просмотров: 248) ответил my504 на Вопрос про Си. (Кейл5 С99) Как правильно выделить место во флеше в размере одной страницы (0x400) для эмуляции EEPROM и задать одно первое значение, оставив остальной массив непрошитым (0xFFFFFFFF).
Ну например так 

#pragma pack(push,0x400)

const unsigned long m[0x400/4]={

0x00000001,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,

};

#pragma pack(pop)


Но я бы так не делал, при загрузке память будет обновляться
