Вот командный файл линкера:

# peripheral registers

}
------------------------------------------------------------------
определяю массив так:
-----------------------------------------------
#pragma use_rodata on
const unsigned int data[1000] = {1,2,3,...};
#pragma use_rodata off
-----------------------------------------------
Во внешнюю ОЗУ пишет хорошо. Когда линкеру говорю, что надо писать в p_Code или x_internal_ROM, туда не записывает, то что надо.
Вродь понятно объяснил :-)
Где косяк может быть?
