Hi all,
I need to redefine the start-up procedure of my application and put it
at a specific address in my flash memory. However, I have problem
redefining it using the NAKED(_reset_vector__) function described in the
MSPGCC documentation. If I try to just duplicate the default function by
adding the following function, my device (msp430f1612) seems to crash.
Can someone help me, please?
Thanks,
Fred
NAKED(_reset_vector__){
extern int _etext;
extern int __data_start;
extern int _edata;
extern int __bss_start;
extern int __bss_end;
Byte1_t *b1Src;
Byte1_t *b1Dst;
// Stop watchdog timer
WDTCTL = WDTPW + WDTHOLD;
// Initialize the .data segment
b1Src = (Byte1_t*)_etext;
b1Dst = (Byte1_t*)__data_start;
while(b1Dst != (Byte1_t*)_edata){
*b1Dst = *b1Src++;
*b1Dst++;
}
// Clear the .bss segment
b1Dst = (Byte1_t*)__bss_start;
while(b1Dst != (Byte1_t*)__bss_end){
*b1Dst = 0;
*b1Dst++;
}
// Jump to main
__asm__ __volatile__("br #main"::);
}
