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++ Problem
when I initilaze at least one of the arrays or three of them , the error will be disappeared.
float Data_Set_X[15000]={0};
float Data_Set_Y[15000];
float Data_Set_Z[15000];
in linker script file it is written that:
/* Specify the memory areas */
MEMORY
{
RAM_EXEC (rx) : ORIGIN = 0x24000000, LENGTH = 256K
RAM (xrw) : ORIGIN = 0x24040000, LENGTH = 256K
}
/* The startup code goes first into RAM_EXEC */
/* The program code and other data goes into RAM_EXEC */
/* Constant data goes into RAM_EXEC */
/* Initialized data sections goes into RAM, load LMA copy after code */
and there is a separated part of the RAM for /* Uninitialized data section */ according to the linker script.
the RAM size is 1MB and around 800KB is accessible for the user. MCU has dual core and I use the M7 Core. this core can access to a 512KB RAM area as it is mentioned in the Linker Script file. the whole size of these three arrays are 180KB
I have attached the linker script file to this message.
Thank you!
