MC9S12G128 bootloader remapping the interrupt vector table

920065012 — Tue, 28 Nov 2017 12:21:54 GMT

I design the bootloader for 9S12G128 ，I need to remapping the interrupt vector table from 0xFF80-0xFFFF, I make some code like that（under words），the code can not work, when I reset ，the code can not enter into the main (); Is there where I need to set up?

#define __CPU_VECTOR_BASE_ADDR__ 0x7F80
/* ISR prototype */
typedef void (*near tIsrFunc)(void) ;
/*lint -save -e950 Disable MISRA rule (1.1) checking. */

#pragma CODE_SEG __NEAR_SEG NON_BANKED

interrupt void UnimplementedISR(void) //定义在NON_BANKED区
{}
void interrupt T0_inter(void)
{}
void interrupt T2_inter(void)
{}
void interrupt CAN_receive(void)
{}

#pragma CODE_SEG DEFAULT

static const tIsrFunc _InterruptVectorTable[] @__CPU_VECTOR_BASE_ADDR__ = {
/* Interrupt vector table */
/*put your ISR functions list here according to the interrupt vector order*/
&UnimplementedISR, /* vector 63 */
&UnimplementedISR, /* vector 62 */

&UnimplementedISR, /* vector 06 */
&UnimplementedISR, /* vector 05 */
&UnimplementedISR, /* vector 04 */
&UnimplementedISR, /* vector 03 */
&UnimplementedISR, /* vector 02 */
&UnimplementedISR, /* vector 01 */
&UnimplementedISR, /* Reset vector */

};

void main(void)
{ IVBR = 0x7F;
//set the vector base

}

Is there where I need to set up?

Hi,

It seems to be correct.

The attached example works on my side.

So please try it.

Regards,

Daniel

Hi,thank you for your help.There are still have some problems.

I open your example,I notice that you use" P&E USB BDM muitilink", I use "TBDML " download the program to MC9S12G128,But it can not works.What's wrong with it?Did you change the file,such as"project.prm" and"start12.c".

if MC9S12G128 connected with CW software,when I use the resert button in CW software,it can do well.

but,if I use buton in hardware reset ,it can't work,like that:
