Re: [avr-gcc-list] switch from application to bootloader section

[Yannick PODGORSKI]

Don't you make the opposite ?

 

to switch app section to boot section is:

 

//....

cli();

GICR = (1<<IVCE);

GICR = (1<<IVSEL);

void (*function)(void) = 0x1E000

function();

 

Anyone know how to switch interupt vector from bootloader section to application section ?

I Try :

 

//...

cli();

GICR = (1<<IVCE);

GICR = (0<<IVCE);                                // try this

void (*function)(void) = 0x0000

function();

//...

 

Can you give more details :

- what happen ?

 

Do you disable watch dog ?

but didn't work.
