Разбираюсь с an2594. при добавлении файлов из данного апнота в проект и попытки откомпилировать, возникают две ошибки:

Ошибку я понимаю так что при сборке в секцию:
Цитата
.ARM.attributes :
{
*(.ARM.attributes)
} > FLASH
{
*(.ARM.attributes)
} > FLASH
пытается записаться несколько значений.
Предполагаю что ЛД файл нужно настроить так чтобы всё в нём размещалось в начале ФЛЕША, а те страницы которые предназначены для записи в конце флеша. Но вот какие секции у меня попадают в конец флеша я не пойму.
Уже в MEMORY создал EXTMEMB0 (rx) : ORIGIN = 0x0805F000, LENGTH = 4K но видимо это не всё.
