I make two different program, application and
bootloader for ATMEGA8
I compile both separately. My bootloader program
size is 512 byte, so I located in smallest bootloader section (Address
1E00h).
I want my program some time switch from bootloader
section to application section and vice versa.
The bootloader program have a function to reprogram
the flash (app section only, coz I I block spm command for boot
section).
Could You help me ?

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.
