Cómo reubicar los vectores de interrupción MSP430FR5969

0

No puedo encontrar la manera correcta de reubicar Vectores de Interrputs con CCS6.2 para MSP430FR5969.

La aplicación led parpadeante utiliza TIMER_A0:

#include "msp430.h"

#define DOUBLE_BLINK


//#pragma LOCATION(main, 0xF000)
void main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT

  PM5CTL0 &= ~LOCKLPM5;

  // Setup GPIO
  P1OUT &= ~0x01;                           // Set P1.0 to output low
  P1DIR |= 0x01;                            // P1.0 output

  // Setup Timer_A3
  TA0CCTL0 = CCIE;                          // TA0CCR0 interrupt enabled
  TA0CCR0 = 32768;                          // ~1s
  TA0CTL = TASSEL_1 + MC_2;                 // ACLK, contmode

  P1OUT |= 0x01;                            // P1.0 = On
  __delay_cycles(500000);                   // Wait 500ms
  P1OUT &= ~0x01;                           // P1.0 = Off


  __bis_SR_register(LPM0_bits + GIE);       // Enter LPM0 w/ interrupt
}


// Timer A0 interrupt service routine
#pragma vector = TIMER0_A0_VECTOR
__interrupt void Timer0_A(void)
{
    P1OUT |= 0x01;                            // P1.0 = On
    __delay_cycles(100000);                   // Wait 100ms

#ifdef DOUBLE_BLINK
    P1OUT &= ~0x01;                           // P1.0 = Off
    __delay_cycles(100000);                   // Wait 100ms
    P1OUT |= 0x01;                            // P1.0 = On
    __delay_cycles(100000);                   // Wait 100ms
#endif

    P1OUT &= ~0x01;                           // P1.0 = Off
    TA0CCR0 += 32768;                         // Add Offset to TA0CCR0 (~1s)
}

Este código funciona bien con ubicaciones de vectores de interrupción estándar: aquí está el enlazador:

-l msp430fr5969.cmd

Pero cómo hacerlo si quiero mover todos los vectores de Interputado después del FRAM (0x4400 + 0xBB00 = 0xFF00) (Mueva IV 0x80 antes de la dirección estándar).

El objetivo es ajustar esta aplicación con Custom Bootloader.

Thx,

La tabla de vectores de interrupción se encuentra en una dirección fija en FRAM (0xFF80) o en una dirección fija en SRAM (0x2380). No es posible moverlo "después del FRAM".

Para mover la tabla a la memoria RAM,

  1. ajusta la secuencia de comandos del vinculador para mover la pila fuera del camino;
  2. copie sus vectores de interrupción al final de la SRAM;
  3. establece el bit SYSRIVECT.

Aunque no puede mover libremente los vectores, puede "saltar" desde las subrutinas de vectores de su cargador de arranque a las direcciones conocidas, que puede seleccionar como desee. Al conocer estas direcciones, puede implementar una tabla de vectores de interrupción de tipo secundario (digamos en la sección de código separada, que puede administrar desde su script de vinculador). Esto le proporcionará la flexibilidad que está buscando para que su aplicación se inicie desde su cargador de arranque personalizado.
