Try to run all code from RAM memory

chiko diko

Hi.

I have a problem, I want to run all my code from RAM memory.
I try to do it with a scatter file.
But after alot of experiments, I think it's cannot be done, because the interrupts vector has to be in the flash. And it's mean that in any interrupt I will 'go' to flash in an interrupt.

So there is another way to run all my code from the RAM?
If not how the scatter file should be looked like?

Thnks.
