If we initialize an array would it be stored in a different partition of RAM in comparison with the condition under which we do not initialize the array ? initialized array: float Data_Set_X[15000]={0}; uninitialized: float Data_Set_X[15000];

the problem is that When I define the arrays like this :float Data_Set_X[15000]; float Data_Set_Y[15000]; float Data_Set_Z[15000];I get the RAM overflow error which is: `.bss' will not fit in region `RAM' Timer-Blink-Test_CM7 C/C++ Problemwhen I init...
