flash details

vinkar · ‎02-25-2014

Hello ,

I am writing a small chunk of code on my KL05 (32KB flash).

After building, I have gioven generate .hex option. I am getting a hex file

abt 19KB. My aim is to use this to drive a sensorless BLDC. The LPC2121

uses abt 6KB of its 32KB flash. WHy is Kinetis using 19KB.

How can I look at the flash usage (does code warrior have one, a la MPLAB).

Is the hex file programmed into the controller. Or is it something else.

My code is below

#include "derivative.h" /* include peripheral declarations */

#define uartEnable UART0_C2 |= UART0_C2_TE_MASK| UART0_C2_RE_MASK; // UART is enabled //

#define uartDisable UART0_C2 &= ~ (UART0_C2_TE_MASK| UART0_C2_RE_MASK); // UART is disabled //

#define luvOceansModeStartup

#define normalModeStartup;

#define startupBrakeTime 150

hi karuvat,

Please make sure optimization level chosen by you is optimize size(-Os).

Please check your project compile generated map file about memory usage.

I suggest to use CodeWarrior GCC compiler, which has higher compile performance for Kinetis product.

Wish it helps.

Best regards,
