Надо ли что-нить дополнительно настраивать в компиляторе? (uVision4) Для переменных эта память не используется - там будет лежать один здоровый массив в заранее известных адресах...

Весь мозг сломал пока в даташит пялился. Оказалось все куда проще: непропай в шине адреса. На козу прозванивал, а на контакт не додумался. День на такую глупость потратил... Верно сказано что электроника - наука о контактах...

 

Остался вопрос о настройках компилятора - надо ли чего туда прописывать? Допустим мне надо переменные в эту память положить... Где ее размер и адрес вписать я уже нашел. Только вот как компилеру показать что я хочу переменную туда положить, а не во внутреннюю память?

Может быть, так:

uint16_t Var __attribute__((at(0x60000000)));
