Is there a more elegant solution than adding a dummy function?
Can I search the next RET instruction or something like this?
----------------------------
I think something like (be sure to check the syntax, I'm typing this
from
memory!):
unsigned char *rampointer;
void prog_function()
{
...function...
}
void next_to_prog_function()
{
//dummy function
}
memcpy(rampointer, progfunction, next_to_prog_function-prog_function);
(void*())(rampointer)(); //execute function from ram
Rampointer is the pointer to the memory area (make sure you initialize
this). prog_function is the function you want to copy to ram.
next_to_prog_function is a dummy function which identifies the end of
prog_function. Don't forget function names are pointers to their
function
in C.
You should also consider what to do when programming is finished.
Probably
a call to the reset vector. It is a good idea to make a function which
blinks an LED and runs this from RAM first.
