Hi All, Currently using KEIL 4 for my development. I am using STM32F427, my application is 210KB but the available SRAM is 192KB. I wanted to use 64KB CCM, how to use and define that CCM in KEIL. Kindly guide with examples how to use the CCM in KEIL.

Thanks for capturing my post, just tried a piece of code as follows and started looking into Memory window to check whether the values are stored
#include "stm32f4xx.h"
char buf[16] __attribute__ ((section(".ccm")));
void main(void) { int i;
for (i=0;i<16;i++) { buf[i] = i; }
}
But it doesn't show any values in the Memory Window, as you suggested I updated the scatter file. Could you guide on this.
OOPS I made a mistake corrected here, now able to see the values storing in that variable. Is that can I use CCM as RO or RW section?
