Posted on March 28, 2013 at 17:14I call system_init function only in bootloader code :
Reset_handle for bootloader is
void Reset_Handler(void)
{
/* FSMC Bank1 NOR/SRAM3 is used for the STM3210E-EVAL, if another Bank is
required, then adjust the Register Addresses */
// SystemInit_ExtMemCtl();
SystemInit ();
/* restore original stack pointer */
asm('' LDR r0, =_estack'');
asm('' MSR msp, r0'');
/* Initialize data and bss */
__Init_Data();
NVIC_SetVectorTable(0x08000000, 0x0);
/* Call the application's entry point.*/
main();
}
for appli is
void Reset_Handler(void)
{
/* FSMC Bank1 NOR/SRAM3 is used for the STM3210E-EVAL, if another Bank is
required, then adjust the Register Addresses */
//SystemInit_ExtMemCtl();
// SystemInit ();
/* restore original stack pointer */
// asm('' LDR r0, =_estack'');
// asm('' MSR msp, r0'');
/* Initialize data and bss */
// __Init_Data();
NVIC_SetVectorTable(0x08000000, 0x1000);
/* Call the application's entry point.*/
main();
}
when i execute only the application it run correcttly (flashing led)
when i execute bootloader with application without interruption (flashing led) work correctly
but when i execute bootloader with application that use timer interruption don't work
it is clear my problem?
thanks
