Re: How to execute code from RAM (STM32F3 CCM RAM)

I already browsed through many doscussions in order to find what I ma looking for. I think your idea is sensible and will work but I don't have any file named vectors.c
and the only place where I find my vector is in a startup_stm32f3303xc.s. How do you think, is it a good idea to invoke the memcpy ...

Re: How to execute code from RAM (STM32F3 CCM RAM)

I have such files in my project, I have also asked on stm32 forum but the only thing I got was that I have to write or change my linker script file.
So the result is the same. There are no ready, supported functions which do map code and ISR vector to RAM

Re: How to execute code from RAM (STM32F3 CCM RAM)

Hello,
this will be the first time for me to try this so I have many doubts. First question is about correct placing those linker files. Where should
I put them so that during a debbug proccess everything would be fine. Second question is about moving ISR vector to RAM.
I guess it is not as simple ...
