Posted on May 17, 2011 at 13:17Hi all,
I use STM32F103ZCT6 144pin to add nor flash,
My main program put in nor flash memory ,and procedure that often uses put in STM32F103ZCT6 flash memory(ex, LCD function delay function).
when main program call delay function,
if I use debug ''Step Into'' is ok,
but I use debug ''Go'', Error appears, into ''HardFaultException()''.
STM32F103ZCT6 flash memory code:
use stm32f10x_flash.icf
add
''define symbol __ICFEDIT_region_Dly1m_start__ = 0x08010000;''
''define symbol __ICFEDIT_region_Dly1m_end__ = 0x08010040;''
''place at address mem:__ICFEDIT_region_Dly1m_start__ { readonly section Dly1m };''
my delay.h
#pragma location=''Dly1m''
void _Dly1m(void);
//========================================================
Nor flash memory code:
use stm32f10x_nor.icf
my main.c
typedef void (*FuncPtr)(void);
FuncPtr _Dly1m;
viod main(void)
{
_Dly1m = (FuncPtr)0x08010000;
:
:
_Dly1m(); // ''Step Into'' is ok,but ''Go'' is Error.

}
